For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following is for reference. Figures 1-6 An intake assembly 100 of an engine according to an embodiment of the present invention is described.

[0042] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, an intake assembly 100 for an engine includes: a control valve assembly 4 and at least two intake pipes, wherein the opening heights of the intake ports of the at least two intake pipes are different, the control valve assembly 4 cooperates with the at least two intake pipes respectively to control the opening or closing of each intake pipe, and the outlet ports of the at least two intake pipes are adapted to be connected to an engine.

[0043] In this embodiment of the application, the engine intake assembly 100 is provided with multiple intake pipes, and the opening heights of the intake ports of at least two intake pipes are different, so the vehicle 1000 can selectively use intake pipes with intake ports of different heights to intake air.

[0044] It should be understood that the wading depth of vehicle 1000 can be determined by the first water level sensor on vehicle 1000.

[0045] When vehicle 1000 is not in water, it can control any one or more intake pipes to take in air via control valve assembly 4, as long as the engine is running. When vehicle 1000 is wading through water, it can select intake pipes with different heights based on the wading depth. For example, in some specific application scenarios, the opening height of multiple intake pipes is higher than a first set water level. When the wading depth is lower than the first set water level, vehicle 1000 can control any one or more intake pipes to take in air via control valve assembly 4, as long as the engine is running. When the wading depth reaches the first set water level, the intake pipe with the lowest opening height is at risk of water entering the engine. Vehicle 1000 can control the intake pipe with the highest opening height to open and the other intake pipes to close via control valve assembly 4, effectively reducing the risk of water entering the engine and improving the safety and reliability of vehicle 1000 when wading through water.

[0046] In this embodiment of the application, the intake assembly 100 is provided with multiple intake pipes, which also helps to reduce the intake temperature of the engine. For example, the vehicle 1000 can select the intake pipe with the lowest intake temperature to intake air according to different operating conditions, while ensuring the safe operation of the engine.

[0047] Lower intake air temperature reduces engine knocking tendency, which helps reduce fuel consumption and engine exhaust temperature. Lower exhaust temperature also lowers exhaust pipe wall temperature, reducing the risk of thermal damage to surrounding components and thus improving the overall performance of the vehicle's thermal management system.

[0048] It should be noted that the vehicle 1000 can select different intake pipes to reduce the intake air temperature based on different driving speeds. Alternatively, the vehicle 1000 can select the intake pipe with the lowest temperature based on the temperature detected by different intake pipes, as long as the engine's intake air temperature can be reduced.

[0049] According to an embodiment of the present invention, the engine intake assembly 100 is provided with multiple intake pipes. The vehicle 1000 can select different intake pipes for air intake according to different operating conditions. For example, the vehicle 1000 can select intake pipes with different intake port heights according to different wading depths, which effectively reduces the risk of water entering the engine and improves the safety and reliability of the vehicle 1000 when wading. The vehicle 1000 can also select different intake pipes for air intake according to different intake pipe temperatures, which helps to reduce the engine intake temperature and weaken the engine knock tendency.

[0050] Reference Figure 1 , Figure 2 and Figure 3In some embodiments, the control valve assembly 4 includes a plurality of on / off valves 41, which are respectively coupled to a plurality of air intake pipes, and each on / off valve 41 is used to control the opening or closing of the corresponding air intake pipe.

[0051] In this embodiment, each intake pipe is equipped with an on / off valve 41, which can control the opening or closing of the corresponding intake pipe by controlling the opening and closing state of the on / off valve 41, thereby improving the reliability of the intake assembly 100.

[0052] In some specific embodiments, each on / off valve 41 is provided with a first driving member 411, which is used to drive the on / off valve 41 to switch between an open state and a closed state. The first driving member 411 can be a motor, an electric push rod, a cylinder or other driving member, and this application does not limit it.

[0053] In other embodiments, the on / off valve 41 can also be a ball valve, solenoid valve, pneumatic valve or other valve, as long as it can control the opening and closing of the corresponding air inlet pipe.

[0054] It should be understood that the on / off valve 41 can also be a multi-way valve, as long as the controlled intake pipe can switch between being connected to the engine and being disconnected from the engine.

[0055] In other embodiments, the control valve assembly 4 may also be a multi-way valve, one end of which is adapted to be connected to the engine, and the other ends of which are respectively connected to multiple intake pipes. The multi-way valve can be switched to connect to any intake pipe and the engine.

[0056] In some embodiments, the intake assembly 100 further includes a temperature detector 8, at least a portion of the intake port is provided with a temperature detector 8 for detecting its temperature, and the control valve assembly 4 is configured to control the opening and closing of each intake pipe based on the detection result of the temperature detector 8.

[0057] In this embodiment, by setting a temperature detector 8 at the air intake, the vehicle 1000 can accurately select the intake pipe with the lowest intake temperature. The lower intake temperature reduces the tendency of engine knocking, which helps to reduce engine fuel consumption and reduce engine exhaust temperature. The reduction in engine exhaust temperature will cause the exhaust pipe wall temperature to decrease, thus reducing the risk of thermal damage to surrounding components from the exhaust pipe, thereby improving the overall performance of the vehicle's thermal management system.

[0058] In some specific embodiments, each air inlet is provided with a temperature detector 8 for detecting its temperature.

[0059] By installing a temperature detector 8 at each air intake, the vehicle 1000 can more accurately determine the intake temperature of each air intake, thereby selecting the air intake with the lowest temperature and effectively reducing the engine's intake temperature.

[0060] It should be noted that the temperature detector 8 can be located above, below, to the left, or to the right of the air inlet, as long as it can detect the temperature at the air inlet. This application does not limit the specific installation location of the temperature detector 8. In other embodiments, the temperature detector 8 can also be located inside the air inlet pipe.

[0061] In some embodiments, the plurality of air intake pipes include a first air intake pipe 2 and a second air intake pipe 3. The first air intake port 24 of the first air intake pipe 2 is disposed in a first direction, and the second air intake port 31 of the second air intake pipe 3 is disposed in a second direction. There is an angle between the first direction and the second direction.

[0062] Through the above technical solution, the first air intake and the second air intake are oriented differently, which increases the distance between the first air intake 24 and the second air intake 31. The environment of the second air intake 31 is different from that of the first air intake 24. Under different driving conditions of the vehicle 1000, the temperature at the first air intake 24 is different from that at the second air intake 31, which allows the vehicle 1000 to select different air intakes according to different judgment conditions, further improving the applicability of the air intake component 100.

[0063] Reference Figure 1 , Figure 3 and Figure 4 In some specific application scenarios, the air intake assembly is located in the front compartment of the vehicle, with the first air intake port 24 of the first air intake pipe 2 facing the front of the vehicle, and the second air intake port 31 of the second air intake pipe 3 facing the left or right side of the vehicle.

[0064] It should be noted that the first direction and the second direction refer to the relative directions of the air intake components. When the air intake components are installed in the vehicle, the second direction is parallel to the left and right direction of the vehicle, and the first direction has an angle with the front and rear direction of the vehicle, so that the heights of the first air intake and the second air intake are different.

[0065] In this embodiment, the first air intake 24 of the first air intake pipe 2 is positioned forward, allowing it to face the front of the vehicle. When the vehicle 1000 is moving, the first air intake 24 is positioned to face the wind, improving the air intake efficiency of the first air intake pipe 2. The second air intake 31 of the second air intake pipe 3 is positioned to the left or right, allowing it to be located on the left or right side of the vehicle 1000, increasing the distance between it and the first air intake 24. The environment of the second air intake 31 is similar to that of the first air intake 24. Unlike other vehicles, the temperature at the first air intake 24 and the temperature at the second air intake 31 differ under different driving conditions of the vehicle 1000. This allows the vehicle 1000 to select different air intakes based on different conditions, further improving the applicability of the air intake assembly 100. In addition, the second air intake 31, located on the left or right side of the vehicle 1000, has a lower risk of water entering due to wave surges when the vehicle 1000 is driving through water compared to the first air intake 24 located on the front side of the vehicle.

[0066] Reference Figure 1 , Figure 3 and Figure 4 In some further embodiments, the first air inlet 24 is set lower than the second air inlet 31, which further increases the distance between the first air inlet 24 and the second air inlet 31. This is beneficial to increasing the temperature difference between the first air inlet 24 and the second air inlet 31, and makes it more advantageous for the vehicle 1000 to select the lower temperature air inlet pipe.

[0067] When the wading depth of vehicle 1000 is below the first set water level, vehicle 1000 can select the intake pipe with the lowest intake temperature according to different intake air temperatures. When the wading depth reaches the first set water level, there is a risk of water entering the first intake pipe 2. Vehicle 1000 can control the second intake pipe 3 to open and the first intake pipe 2 to close through the control valve assembly 4, effectively reducing the risk of water entering the engine and improving the safety and reliability of vehicle 1000 when wading.

[0068] In some specific embodiments, the first set water level is set to 1m, and the lowest point of the first air inlet 24 is not lower than the first set water level. In other embodiments, the first set water level can also be other heights, such as 0.9m, 1.1m, 1.2m, 1.3m, etc. This application does not limit the specific height of the first set water level.

[0069] In some embodiments, the height difference between the lowest point of the first air inlet 24 and the lowest point of the second air inlet 31 ranges from 0.5 to 0.8 m.

[0070] If the height difference between the lowest point of the first air intake 24 and the lowest point of the second air intake 31 is less than 0.5m, it will result in a small height difference between the two air intakes. When the wading depth is higher than the height of the first air intake 24 but lower than the height of the second air intake 31, there is still a significant risk that external water will enter the second air intake 31 via a surge. Furthermore, a height difference of at least 0.5m between the lowest points of the first air intake 24 and the second air intake 31 helps to increase the distance between them, increasing the temperature difference and allowing the vehicle to select a lower-temperature air intake. However, due to the vehicle's height limitations, the height difference between the lowest points of the first air intake 24 and the second air intake 31 is unlikely to exceed 0.8m.

[0071] In this embodiment, the height difference between the lowest point of the first air inlet 24 and the lowest point of the second air inlet 31 is in the range of 0.5 to 0.8 m. This not only increases the height of the second air inlet 31 and reduces the risk of water entering the second air inlet 31, but also reduces the difficulty of arranging the second air inlet 31. It also makes it easier for the vehicle 1000 to select an air intake pipe with a lower temperature.

[0072] In some specific embodiments, the height difference between the lowest point of the first air intake 24 and the lowest point of the second air intake 31 is 0.6m, which effectively increases the height of the second air intake 31, reduces the risk of water entering the second air intake 31, facilitates the arrangement of the second air intake 31, and improves the applicability of the air intake assembly 100 in different vehicle models. In other specific embodiments, the height difference between the lowest point of the first air intake 24 and the lowest point of the second air intake 31 can also be any one of 0.5m, 0.55m, 0.7m, or 0.8m, or a range between any two.

[0073] Reference Figure 2 and Figure 4 In some embodiments, at least one air intake pipe is provided with a water collection chamber 21, which is used to collect water entering the air intake pipe.

[0074] When vehicle 1000 is driving through water and the wading depth does not reach the first set water level, there is a risk of water entering the intake pipe due to surge. In this embodiment, by setting a water accumulation chamber 21 in the intake pipe, the water entering the intake pipe can stay in the water accumulation chamber 21 instead of flowing directly to the engine along the intake pipe, which effectively reduces the risk of water entering the engine, improves the reliability of the intake assembly 100, and improves the safety of vehicle 1000.

[0075] In some specific embodiments, the first air intake pipe 2 is provided with a water accumulation chamber 21. Because the first air intake port 24 of the first air intake pipe 2 is located on the front side of the vehicle 1000, water is more likely to enter the first air intake pipe 2 when the vehicle 1000 is driving. In this embodiment of the application, by providing a water accumulation chamber 21 in the first air intake pipe 2, the risk of water entering the engine is effectively reduced.

[0076] In some embodiments, a portion of the intake pipe bends downward to form a water accumulation chamber 21.

[0077] In this embodiment, the formation of the water accumulation cavity 21 is simple, which reduces the processing difficulty of the air intake pipe.

[0078] It should be understood that in other embodiments, a portion of the intake pipe may extend downward to form a groove-like structure to form a water accumulation cavity 21, or the cross-section of a portion of the intake pipe may be increased to form a water accumulation cavity 21, as long as a space that can be used to contain water is formed inside the intake pipe. This application does not limit the specific formation method of the water accumulation cavity 21.

[0079] In some embodiments, the water accumulation chamber 21 is located between the air inlet and the control valve assembly 4.

[0080] With the above technical solution, the water in the water accumulation chamber 21 must pass through the control valve assembly 4 before it can continue to flow to the engine, which increases the difficulty of water entering the engine and further reduces the risk of water entering the engine.

[0081] In some embodiments, the water collection chamber 21 is provided with a drain hole.

[0082] The above technical solution allows the water in the water collection chamber 21 to be drained, preventing the water in the water collection chamber 21 from overflowing and flowing into the engine. This allows the water collection chamber 21 to be reused, effectively reducing the risk of water entering the engine and effectively improving the reliability of the air intake assembly 100.

[0083] In some embodiments, the air intake pipe is provided with a drain valve 22 for controlling the opening or closing of the drain hole.

[0084] If the drain valve 22 is not provided, the drain hole will always be open, allowing outside air to enter the intake pipe and affecting the accuracy of the air temperature detection within the intake pipe, thus affecting the engine's intake air temperature. Therefore, this embodiment of the application includes a drain valve 22 that can close the drain hole. When there is no need to drain water from the water accumulation chamber 21, the drain hole is closed by the drain valve 22, ensuring the reliability of air intake through the intake port.

[0085] In some specific embodiments, the drain valve 22 includes a second drive member 221 and a plug 222. The second drive member 221 is used to drive the plug 222 to move. When it is necessary to close the drain hole, the second drive member 221 drives the plug 222 to move to block the drain hole. When it is necessary to open the drain hole, the second drive member 221 drives the plug 222 away from the drain hole.

[0086] It should be noted that the second driving component 221 can be a motor, electric push rod, cylinder or other driving component, as long as it can drive the plug 222 to switch between blocking the drain hole and avoiding the drain hole.

[0087] In some embodiments, the air intake assembly 100 further includes a first detection module 23 for detecting the water level in the water accumulation chamber 21, and the drain valve 22 is configured to open or close the drain hole based on the detection result of the first detection module 23.

[0088] In this embodiment, the drainage hole can be opened or closed based on the detection result of the first detection module 23, making the drainage of the water accumulation chamber 21 more intelligent and improving the reliability of the air intake assembly 100.

[0089] In some specific embodiments, the first detection module 23 is a water pressure sensor. The water pressure sensor determines the amount of water in the water accumulation chamber 21. When the water pressure detected by the water pressure sensor is lower than the set value, the drain valve 22 remains closed. When the water pressure detected by the water pressure sensor reaches the set value, the drain valve 22 is controlled to open the drain hole to drain water.

[0090] In other embodiments, the first detection module 23 may also be a second water level sensor, which detects the amount of water accumulated by detecting the water level in the water accumulation chamber 21. When the water level detected by the second water level sensor is lower than the set value, the drain valve 22 remains closed. When the water level detected by the second water level sensor reaches the set value, the drain valve 22 is controlled to open the drain hole to drain water.

[0091] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the intake assembly 100 further includes a main intake pipe 1, the first end of which is connected to the engine's air intake port; and one end of a plurality of intake pipes is connected to the second end of the main intake pipe 1.

[0092] Multiple intake pipes are connected to form a whole by the main intake pipe 1, which facilitates the overall installation of the intake assembly 100. When connecting the intake assembly 100 to the engine, only the first end of the main intake pipe 1 needs to be connected to the engine, which effectively improves the assembly efficiency of the intake assembly 100.

[0093] In some embodiments, a filter 6 is provided between the plurality of air intake pipes and the main air intake pipe 1.

[0094] By setting up filter 6, the air entering the main intake manifold 1 can be filtered, preventing moisture, debris, and other contaminants in the air from entering the engine and ensuring the reliability of engine operation.

[0095] In some further embodiments, the main intake manifold 1 is also provided with a turbocharger 7, which can increase the intake pressure of the engine, improve combustion efficiency, and improve the working efficiency of the engine.

[0096] The following is based on the appendix Figure 1-6 A specific embodiment of this application is described.

[0097] The intake assembly 100 of the engine according to an embodiment of the present invention includes: a control valve assembly 4 and a plurality of intake pipes, the plurality of intake pipes being arranged at intervals, at least two intake ports having different opening heights, and the control valve assembly 4 cooperating with the plurality of intake pipes to control each intake pipe to open or close.

[0098] The control valve assembly 4 includes multiple on / off valves 41, which are respectively matched with multiple air intake pipes. Each on / off valve 41 is used to control the opening or closing of the corresponding air intake pipe.

[0099] The opening and closing valve 41 is a ball valve, and each opening and closing valve 41 is equipped with a first driving element 411 for driving. The first driving element 411 is a motor.

[0100] The intake assembly 100 also includes a plurality of temperature detectors 8, each of which is provided with a temperature detector 8 for detecting its temperature.

[0101] The multiple air intake pipes include a first air intake pipe 2 and a second air intake pipe 3. The first air intake port 24 of the first air intake pipe 2 is arranged facing forward, and the second air intake port 31 of the second air intake pipe 3 is arranged facing to the right.

[0102] The first air intake 24 is positioned lower than the second air intake 31.

[0103] The first set water level is set to 1m, and the lowest point of the first air inlet 24 is not lower than the first set water level.

[0104] The height difference between the lowest point of the first air inlet 24 and the lowest point of the second air inlet 31 is 0.6m.

[0105] The first air intake pipe 2 is provided with a water collection chamber 21, which is used to collect water entering the air intake pipe.

[0106] A portion of the intake pipe bends downward to form a water collection chamber 21. The water collection chamber 21 is located between the intake port and the on / off valve 41.

[0107] The water accumulation chamber 21 is provided with a drain hole. The air inlet pipe is provided with a drain valve 22 for controlling the opening or closing of the drain hole. The drain valve 22 includes a second drive member 221 and a plug 222. The second drive member 221 is used to drive the plug 222 to move. When it is necessary to close the drain hole, the second drive member 221 drives the plug 222 to move to block the drain hole. When it is necessary to open the drain hole, the second drive member 221 drives the plug 222 away from the drain hole. The second drive member 221 is a motor.

[0108] The air intake assembly 100 also includes a first detection module 23 for detecting the water level in the water accumulation chamber 21, and the drain valve 22 is configured to open or close the drain hole based on the detection result of the first detection module 23.

[0109] The first detection module 23 is a water pressure sensor. The water pressure sensor determines the amount of water in the water accumulation chamber 21. When the water pressure detected by the water pressure sensor is lower than the set value, the drain valve 22 keeps the drain hole closed. When the water pressure detected by the water pressure sensor reaches the set value, the drain valve 22 is controlled to open the drain hole to drain water.

[0110] The intake assembly 100 also includes a main intake pipe 1, the first end of which is connected to the engine's air intake port; one end of a plurality of intake pipes is connected to the second end of the main intake pipe 1. A filter 6 is provided between the plurality of intake pipes and the main intake pipe 1. The main intake pipe 1 is also equipped with a turbocharger.

[0111] According to an embodiment of the present invention, a vehicle 1000 includes an engine and an intake assembly 100, wherein the intake assembly 100 is the intake assembly 100 in the above technical solution, and the outlet end of the intake pipe is connected to the engine.

[0112] According to an embodiment of the present invention, the vehicle 1000 has an engine intake assembly 100 with multiple intake pipes. The vehicle 1000 can select different intake pipes for air intake according to different operating conditions. For example, the vehicle 1000 can select intake pipes with different intake port heights according to different wading depths, which effectively reduces the risk of water entering the engine and improves the safety and reliability of the vehicle 1000 when wading. The vehicle 1000 can also select different intake pipes for air intake according to different intake pipe temperatures, which helps to reduce the engine intake temperature and weaken the engine knock tendency.

[0113] Reference Figure 1 , Figure 3 and Figure 4In some specific embodiments, the air intake assembly 100 is disposed in the front compartment 200 of the vehicle 1000. The air intake assembly 100 includes a first air intake pipe 2 and a second air intake pipe 3. The first air intake port 24 of the first air intake pipe 2 is disposed facing forward. A first air intake area 201 is disposed on the front side of the front compartment 200 of the vehicle 1000. The first air intake port 24 is disposed directly opposite to the first air intake area 201. The second air intake port 31 of the second air intake pipe 3 is disposed facing left or right. A second air intake area 202 is disposed on the left or right side of the front compartment 200 of the vehicle 1000. The second air intake port 31 is disposed directly opposite to the second air intake area 202.

[0114] The intake air temperature of the first intake pipe 2 is significantly affected by the engine, while the intake air temperature of the second intake pipe 3 is less affected. When the vehicle travels at a high speed of 1000 km / h, the engine load is high and the heat generation is large. However, because the vehicle speed is high enough, the overall heat dissipation conditions of the first intake pipe 2 are relatively good, and the temperature inside the first intake pipe 2 is relatively low. A part of the second intake pipe 3 is also located in the front compartment 200 and is also affected by the engine temperature. However, the heat dissipation conditions of the second intake pipe 3 are not as good as those of the first intake pipe 2, which results in the intake air temperature of the first intake pipe 2 being lower than that of the second intake pipe 3. When the vehicle travels at a low speed of 1000 km / h, the engine load is low, and the second intake pipe 3 is less affected by heat. At this time, the intake air temperature of the second intake pipe 3 is lower than that of the first intake pipe 2.

[0115] In this embodiment of the application, the air intake assembly 100 is provided with a first air intake pipe 2 and a second air intake pipe 3. Under different operating conditions, the air intake temperature of the first air intake pipe 2 and the second air intake pipe 3 of the vehicle 1000 is different. Under the condition of ensuring the safe operation of the engine, the air intake pipe with the lowest air intake temperature can be selected for air intake.

[0116] Lower intake air temperature reduces engine knocking tendency, which helps reduce fuel consumption and engine exhaust temperature. Lower exhaust temperature also lowers exhaust pipe wall temperature, reducing the risk of thermal damage to surrounding components and thus improving the overall performance of the vehicle's thermal management system.

[0117] Reference Figure 4 , Figure 5 and Figure 6 According to the control method of vehicle 1000 of the present invention, vehicle 1000 is the vehicle 1000 in the above technical solution. The control method includes: controlling at least one air intake pipe above the wading height to open according to the wading height of vehicle 1000.

[0118] Through the above technical solution, Vehicle 1000 can promptly close the air intake pipe below the wading depth to prevent water from entering the engine, allowing the engine to continue running. Vehicle 1000 can select air intake pipes with different intake heights according to different wading depths, effectively reducing the risk of water entering the engine and improving the safety and reliability of Vehicle 1000 when wading.

[0119] In some specific embodiments, the vehicle 1000 includes an engine and an engine intake assembly 100. The intake assembly 100 includes a first intake pipe 2 and a second intake pipe 3, with the first intake port 24 lower than the second intake port 31. The height difference between the lowest point of the first intake port 24 and the lowest point of the second intake port 31 is 0.6m, and the first set water level is set to 1m. The lowest point of the first intake port 24 of the first intake pipe 2 is not lower than the first set water level.

[0120] The intake assembly 100 also includes a control valve assembly 4, which cooperates with the first intake pipe 2 and the second intake pipe 3 to control the opening or closing of each intake pipe. The control valve assembly 4 is communicatively connected to the control module of the vehicle 1000. It should be noted that the control module can be an on-board computer, a domain controller, or an independently configured control module.

[0121] The vehicle 1000 is also equipped with a first water level sensor, which is used to detect the wading depth of the vehicle 1000. The first water level sensor is in communication with the control module of the vehicle 1000.

[0122] Control methods include:

[0123] When the vehicle is not in water, the control module can select any air intake pipe to intake air through the control valve assembly 4.

[0124] When the vehicle is wading through water at a depth of less than 1m, the control module can select any air intake pipe to receive air through the control valve assembly 4.

[0125] When the vehicle wades through water at a depth of 1m, the control module closes the first air intake pipe 2 and opens the second air intake pipe 3 through the control valve assembly 4.

[0126] Reference Figure 5 In some embodiments, controlling the opening of at least one air intake pipe above the wading depth of the vehicle 1000 includes: when the wading depth is below a first set water level, controlling the air intake pipe with the lowest air intake temperature to open and the remaining air intake pipes to close; and / or, when the wading depth is above the first set water level, controlling the air intake pipe with the highest air intake height to open and the remaining air intake pipes to close.

[0127] Through the above technical solution, when the wading depth is below the first set water level, Vehicle 1000 can select the intake pipe with the lowest intake temperature, thus reducing engine intake temperature, decreasing knocking tendency, allowing the ignition angle to be advanced, increasing combustion efficiency, and reducing overall fuel consumption. When the wading depth is above the first set water level, the intake pipe with the highest control port is opened while the other intake pipes are closed, allowing the vehicle to travel in deeper water. The overall sealing and buoyancy of the vehicle are greatly enhanced, ensuring the safety of Vehicle 1000 when wading.

[0128] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments, the vehicle 1000 includes a first air intake pipe 2 and a second air intake pipe 3, wherein the first air intake port 24 of the first air intake pipe 2 is lower than the second air intake port 31 of the second air intake pipe 3. Controlling the opening of at least one air intake pipe above the wading depth of the vehicle 1000 includes: when the wading depth is lower than a first set water level, controlling at least one of the first air intake pipe 2 and the second air intake pipe 3 to open; and / or, when the wading depth is higher than the first set water level, controlling the second air intake pipe 3 to open and the first air intake pipe 2 to close.

[0129] With the above technical solution, when the wading depth is lower than the first set water level, the vehicle 1000 can choose to open the first air intake pipe 2 and / or the second air intake pipe 3, as long as the normal operation of the engine is met; when the wading depth is higher than the first set water level, only the second air intake pipe 3 with the higher air intake position is opened, so that the engine can continue to run, reducing the risk of water entering the engine and improving the safety of the vehicle 1000 when wading.

[0130] In some embodiments, the control method further includes: when the temperature of the first air inlet 24 is lower than the temperature of the second air inlet 31, controlling the first air inlet pipe 2 to open and the second air inlet pipe 3 to close; and / or, when the temperature of the second air inlet 31 is lower than the temperature of the first air inlet 24, controlling the second air inlet pipe 3 to open and the first air inlet pipe 2 to close.

[0131] Through the above technical solutions, the vehicle 1000 can use the intake pipe with the lowest intake temperature, which reduces the engine intake temperature, reduces the tendency to knock, allows the ignition angle to be advanced, increases combustion efficiency, and reduces the overall fuel consumption of the vehicle.

[0132] Reference Figure 4 , Figure 5 and Figure 6In some specific embodiments, the vehicle 1000 includes an engine and an engine intake assembly 100. The intake assembly 100 includes a first intake pipe 2 and a second intake pipe 3. The first intake port 24 is lower than the second intake port 31. The height difference between the lowest point of the first intake port 24 and the lowest point of the second intake port 31 is 0.6m. The first set water level is set to 1m, and the lowest point of the first intake port 24 of the first intake pipe 2 is not lower than the first set water level.

[0133] The intake assembly 100 also includes a control valve assembly 4, which cooperates with the first intake pipe 2 and the second intake pipe 3 to control the opening or closing of each intake pipe. The control valve assembly 4 is communicatively connected to the control module of the vehicle 1000.

[0134] The intake assembly 100 also includes multiple temperature detectors 8, each of which is equipped with a temperature detector 8 for detecting its temperature, and all multiple temperature detectors 8 are in communication with the control module of the vehicle 1000.

[0135] The vehicle 1000 is also equipped with a first water level sensor, which is used to detect the wading depth of the vehicle 1000. The first water level sensor is in communication with the control module of the vehicle 1000.

[0136] Control methods include:

[0137] When the vehicle has not been submerged in water, the control module selects the intake pipe with the lowest intake temperature through the control valve assembly 4.

[0138] When the vehicle is wading through water at a depth of less than 1m, the control module selects the intake pipe with the lowest intake temperature through the control valve assembly 4.

[0139] When the vehicle wades through water at a depth of 1m, the control module closes the first air intake pipe 2 and opens the second air intake pipe 3 through the control valve assembly 4.

[0140] In some embodiments, the water level in the open air intake pipe is detected, and when the water level exceeds a set condition, the drain hole of the air intake pipe is opened to drain the water.

[0141] The above technical solution can prevent water from overflowing from the water accumulation chamber 21 and reduce the risk of water entering the engine.

[0142] In some specific embodiments, the air intake assembly 100 is disposed in the front compartment 200 of the vehicle 1000. The air intake assembly 100 includes a first air intake pipe 2 and a second air intake pipe 3. The first air intake port 24 of the first air intake pipe 2 is disposed facing forward. A first air intake area 201 is disposed on the front side of the front compartment 200 of the vehicle 1000. The first air intake port 24 is disposed directly opposite to the first air intake area. The second air intake port 31 of the second air intake pipe 3 is disposed on the right side. A second air intake area 202 is disposed on the right side of the front compartment 200 of the vehicle 1000. The second air intake port 31 is disposed directly opposite to the second air intake area 202.

[0143] The first air inlet 24 is lower than the second air inlet 31. The height difference between the lowest point of the first air inlet 24 and the lowest point of the second air inlet 31 is 0.6m. The first set water level is set to 1m. The lowest point of the first air inlet 24 of the first air inlet pipe 2 is not lower than the first set water level.

[0144] The intake assembly 100 also includes a control valve assembly 4, which cooperates with the first intake pipe 2 and the second intake pipe 3 to control the opening or closing of each intake pipe. The control valve assembly 4 is communicatively connected to the control module of the vehicle 1000.

[0145] The intake assembly 100 also includes multiple temperature detectors 8, each of which is equipped with a temperature detector 8 for detecting its temperature, and all multiple temperature detectors 8 are in communication with the control module of the vehicle 1000.

[0146] The vehicle 1000 is also equipped with a first water level sensor, which is used to detect the wading depth of the vehicle 1000. The first water level sensor is in communication with the control module of the vehicle 1000.

[0147] The first air intake pipe 2 is provided with a water accumulation chamber 21, and the water accumulation chamber 21 is provided with a drain hole. The first air intake pipe 2 is provided with a drain valve 22 for controlling the opening or closing of the drain hole. The drain valve 22 is communicatively connected to the control module of the vehicle 1000. The air intake assembly 100 also includes a first detection module 23 for detecting the water pressure in the water accumulation chamber 21, and the first detection module 23 is communicatively connected to the control module of the vehicle 1000.

[0148] Control methods include:

[0149] When the vehicle has not been submerged in water, if the intake temperature of the first intake pipe is higher than that of the second intake pipe, the first intake pipe will be closed and the second intake pipe will be opened; if the intake temperature of the first intake pipe is lower than that of the second intake pipe, the first intake pipe will be opened and the second intake pipe will be closed.

[0150] When the vehicle is wading through water at a depth of less than 1 meter, if the air temperature of the first air intake pipe is higher than that of the second air intake pipe, the first air intake pipe will be closed and the second air intake pipe will be opened; if the air temperature of the first air intake pipe is lower than that of the second air intake pipe, the first air intake pipe will be opened and the second air intake pipe will be closed.

[0151] When the vehicle is wading through water at a depth of less than 1m and the first air intake pipe 2 is open, if the water pressure detected by the first detection module 23 is less than 0.5kPa, the drain valve 22 will remain closed; if the water pressure detected by the first detection module 23 is greater than or equal to 0.5kPa, the drain valve 22 will switch to open the drain hole.

[0152] When the vehicle wades through water at a depth of 1m, the control module closes the first air intake pipe 2 and opens the second air intake pipe 3 through the control valve assembly 4.

[0153] In summary, this invention provides a control method for a vehicle 1000 that adaptively adjusts the engine's intake air temperature to ensure fuel economy. By sensing the vehicle's wading depth and monitoring the intake air temperature, the method automatically adjusts the intake configuration from either the first intake pipe 2 or the second intake pipe 3 to ensure normal engine operation. During normal land driving, temperature detectors located on the first intake pipe 2 and the second intake pipe 3 simultaneously monitor the intake air temperature. By comparing the temperatures detected by the two detectors, the method automatically closes or opens the first intake pipe 2 and the second intake pipe 3, ensuring the lowest possible engine intake air temperature, reducing knocking tendency, improving combustion efficiency, and decreasing overall fuel consumption.

[0154] When vehicle 1000 is driving through water, the vehicle system has a first water level sensor, which is used to sense the depth of water that vehicle 1000 is wading through. By adjusting the air intake from the first air intake pipe 2 or the second air intake pipe 3, it is ensured that no water enters the engine and causes damage to the cylinder block when wading through water.

[0155] When the vehicle is wading through low water levels and the air temperature of the first air intake pipe 2 is low, the air intake port of the first air intake pipe 2 opens. The pressure sensor at the bend of the first air intake pipe 2 automatically detects the water pressure in real time. When the pressure is too high, the drain valve 22 opens, and the water will be discharged from the drain hole to prevent corrosive damage to the engine. When the water pressure is low, the drain valve 22 remains stationary. If the air temperature of the first air intake pipe 2 is high at this time, the second air intake pipe 3 opens, which both prevents water from entering and reduces the air temperature. When the wading through high water levels, the second air intake pipe 3, which has a higher air intake port, opens to ensure normal engine operation and normal vehicle operation. This system achieves the goals of high water level waterproofing, low water level wading monitoring, and intelligent drainage.
