Description

Air intake structure, vehicle, and air intake control method

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 5, 2024, with application number 202410167013.1 and application name “Intake Structure, Vehicle and Intake Control Method”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicles, and in particular to an air intake structure, a vehicle, and an air intake control method. Background Art

[0003] The front of the vehicle is equipped with an air intake grille, which forms a channel for air circulation and can provide air to the engine so that the air and exhaust gas are mixed for combustion, thereby reducing fuel consumption through exhaust gas recirculation.

[0004] However, it was found during use that when the vehicle is traveling in a low-temperature environment, the temperature of the air entering the engine is too low, causing the engine to operate in a low-temperature condition, resulting in poor fuel evaporation and atomization, and worsening engine fuel consumption and emissions; and if the humidity in the air is high, it will also cause water vapor to condense or freeze. Therefore, in the existing technology, the air intake grille will be closed in a low-temperature environment to prevent the engine temperature from being too low, but closing the air intake grille will result in insufficient air participating in exhaust gas recirculation, resulting in increased fuel consumption.

[0005] Therefore, how to ensure the engine's intake temperature and improve the efficiency of exhaust gas recirculation in a low-temperature environment has become an urgent problem to be solved.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0042] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the numbers used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0044] As shown in Figures 1 and 2, the present application provides an air intake structure 100, wherein the air intake structure 100 includes a first channel 11 and a second channel 12, and the first channel 11 and the second channel 12 are both through along the front and rear directions of the vehicle, and the first channel 11 and the second channel 12 both have a first end and a second end, and the first end is an end facing the rear of the vehicle, and the second end is an end facing the front of the vehicle.

[0045] The first end of the first channel 11 is connected to the first end of the second channel 12, and the second end of the second channel 12 is connected to the atmosphere. The air intake of the vehicle's engine is arranged inside the first channel 11, that is, the air intake of the engine is connected to the second channel 12 through the first channel 11, and the pressure inside the second channel 12 is greater than the pressure inside the first channel 11.

[0046] The heating assembly 3 is disposed at the first end of the first channel 11 and / or the first end of the second channel 12 , and is used to heat the air flowing from the second channel 12 into the first channel 11 .

[0047] During the use of the intake structure 100 provided in the present application, after the air enters the second channel 12, it will flow into the interior of the first channel 11 and into the air intake of the engine under the action of pressure; at the same time, since a heating component 3 is provided at the first end of the first channel 11 and / or the first end of the second channel 12, the heating component 3 can effectively heat the air during the flow of air from the second channel 12 to the first channel 11, which is beneficial to increase the intake temperature of fuel vehicles under low temperature conditions, broaden the ambient temperature range in which the engine exhaust gas recirculation can be used, and improve the efficiency of exhaust gas recirculation (EGR).

[0048] Optionally, as shown in Figure 1, the air intake structure 100 provided in the present application is provided with a heating component 3 at the first end of the first channel 11 and the second end of the second channel 12. In the process of air flowing from the second channel 12 to the first channel 11, the air can flow through the two heating components 3 respectively to be heated twice, thereby further increasing the temperature of the air entering the engine air intake.

[0049] As shown in FIG1 , the present application provides an air intake structure 100, wherein an air intake device 2 is provided at the second end of the first channel 11 and the second end of the second channel 12. The air intake device 2 at the first channel 11 is used to control the start or stop of air entering the cabin 201 or directly entering the engine 300, and to adjust the amount of air entering the cabin 201 or directly entering the engine 300 from the first channel 11; the air intake device 2 at the second channel 12 is used to control the start or stop of air entering the cabin 201, and to adjust the amount of air entering the cabin 201 from the second channel 12. The air intake device 2 has an air inlet, and the opening of the air intake device 2 is adjustable to adjust the size of the air inlet. Thus, by adjusting the opening of the air intake device 2 at the second end of the first channel 11, the pressure inside the first channel 11 can be adjusted, and by adjusting the opening of the air intake device 2 at the second end of the second channel 12, the pressure inside the second channel 12 can be adjusted. When the opening degree of the air intake device 2 increases, the air intake port increases, and when the opening degree of the air intake device 2 decreases, the air intake port decreases.

[0050] In the present application, the air intake device 2 may be an air intake grille having air intake holes thereon, the air intake holes forming an air inlet. Of course, the air intake device 2 may also be other structures capable of intake air, and is not limited to an air intake grille. Any structure capable of intake air may serve as the air intake device 2, and the air inlet may also be in other forms.

[0051] The specific position and number of the second channels 12 can be flexibly selected according to design requirements to ensure that sufficient air can be delivered to the engine and the exhaust gas recirculation efficiency of the engine is improved.

[0052] Optionally, the opening of the air intake device 2 provided at the second end of the first channel 11 is smaller than the opening of the air intake device 2 provided at the second end of the second channel 12. This ensures that the pressure inside the first channel 11 is lower than the pressure inside the second channel 12, so that after entering the second channel 12, the air flows toward the first channel 11 under the action of the pressure and then flows into the air intake of the engine.

[0053] As shown in FIG1 , the present application provides an air intake structure 100, wherein the air intake structure 100 is mounted on the front side of a vehicle's engine compartment 201, with the first end of the first channel 11 and the first end of the second channel 12 communicating through the engine compartment 201. The engine 300 is located within the engine compartment 201. As air flows from the second channel 12 to the first channel 11, it is further heated by the heat from the surface of the engine 300 within the engine compartment 201 as it passes through the engine compartment 201. Combined with the two heating components, the air can be heated three times in total, effectively ensuring the heating effect and raising the temperature of the air entering the engine 300.

[0054] As shown in Figures 1 and 3, the air intake structure 100 provided in this application, wherein the heating component 3 is a heat exchange plate, has a smaller size along the front-to-rear direction of the vehicle, and occupies a smaller space in the cabin 201 along the front-to-rear direction of the vehicle after assembly.

[0055] A heat exchange channel 32 for the flow of heat exchange medium is formed inside the heat exchange plate. The heat exchange medium can be hot water or hot air to exchange heat with the air outside the heat exchange plate, thereby heating the air.

[0056] A hollow portion 31 is formed between adjacent heat exchange channels 32. The through direction of the hollow portion 31 is the same as the through direction of the first channel 11 and the through direction of the second channel 12. The hollow portion 31 connects the first channel 11 with the interior of the cabin 201 or the second channel 12 with the interior of the cabin 201. By providing the hollow portion 31, the air can be heated while ensuring smooth circulation of the air.

[0057] As shown in Figures 1 and 2, the air intake structure 100 provided in the present application, wherein the air intake of the engine also includes an air duct 4, which is arranged in the second connecting area at the first end of the first channel 11. The through direction of the air duct 4 is the same as the through direction of the first channel 11. One end of the air duct 4 extends into the interior of the first channel 11, and the other end of the air duct 4 is connected to the air intake of the engine 300, connecting the air intake of the engine 300 with the air duct 4 inside the first channel 11. By setting the air duct 4, the flow direction of the air can be guided and concentrated when the air enters the engine 300, reducing the impact of air turbulence on its flow speed.

[0058] As shown in Figure 2, the air intake structure 100 provided in the present application is connected to the first end of the first channel 11 with a mounting plate 5, and a positioning hole 51 is opened on the mounting plate 5. The air intake of the engine 300 passes through the positioning hole 51 and is connected to the mounting plate 5 to provide an installation basis for the air intake of the engine 300 and ensure the stability of the air intake of the engine 300 after assembly.

[0059] Optionally, the air inlet of the engine 300 may also be directly fixedly connected to the inner surface of the channel, so as to omit the structure of the mounting plate 5 and simplify the installation process of the air inlet of the engine 300 .

[0060] There is a gap between one side edge of the mounting plate 5 and the periphery of the second channel 12 , and the gap communicates with the interior of the first channel 11 and the interior of the nacelle 201 .

[0061] As shown in Figures 1 and 2, the air intake structure 100 provided in the present application includes a base 1, and a first channel 11 and a second channel 12 are both formed on the base 1. Specifically, the base 1 includes a base shell 13 and a partition 14. The base shell 13 is a cylindrical structure that passes through the front and rear directions of the vehicle. The partition 14 is arranged inside the base shell 13 and is sealed and fixedly connected to the inner surface of the base shell 13. The base shell 13 is a plate-like structure extending along the front and rear directions of the vehicle. The interior of the base shell 13 is separated by the partition 14 to form a first channel 11 and a second channel 12 that are independent of each other.

[0062] The air intake structure 100 provided in the present application, wherein the air intake device 2 is an electronically controlled air intake device, which is directly electrically connected to the vehicle's electronic control system. The opening, closing and opening degree of each air intake device 2 are controlled by the vehicle's electronic control system according to the temperature in the operating environment of the engine 300.

[0063] As shown in FIG1 , the present application provides an air intake structure in which the heating component 3 directly adopts the heat dissipation component of the vehicle's engine to realize the recovery and utilization of the engine's waste heat.

[0064] Optionally, the heating component 3 of the air intake structure 100 is connected to the cooling water drain pipe 301 of the engine 300. The temperature of the cooling water increases after cooling the engine 300. At this time, the cooling water drain pipe 301 is connected to the heating component 3, so that the cooling water that has absorbed the heat of the engine 300 can flow into the heating component 3 as a heat exchange medium, and exchange the heat absorbed from the engine 300 to the air to achieve heat recovery and utilization.

[0065] Optionally, the heating component 3 of the air intake structure 100 is connected to the cooling water supply pipe 302 of the engine 300. After the cooling water exchanges heat with the air flowing through the hollow portion 31 while flowing in the heating component 3, the temperature is reduced and the cooling water is transported to the engine 300 again through the cooling water supply pipe 302 to cool the engine 300.

[0066] The present application also provides an air intake system, which includes an engine 300 and the air intake structure as described above;

[0067] An air intake of the engine 300 is disposed inside the first passage 11 .

[0068] As shown in FIG1 , the present application further provides a vehicle, wherein the vehicle includes a vehicle body 200 , an engine 300 , and the air intake structure 100 as described above.

[0069] The vehicle body 200 and the air intake structure 100 are installed on the vehicle body. The air intake device 2 of the air intake structure 100 not only realizes the function of adjusting the air flow state, but also has the function of improving the aesthetics of the vehicle.

[0070] An engine compartment 201 is formed inside the vehicle body 200 for arranging the engine 300 and the air intake structure 100 provided in the present application.

[0071] The engine 300 has an air intake for admitting air to provide oxygen for combustion of fuel.

[0072] Optionally, the vehicle further includes an electronic control system and a temperature sensor. The temperature sensor is located within the air intake of the engine 300. The air intake device 2 and the temperature sensor are both electrically connected to the electronic control system. The electronic control system controls the opening, closing, and degree of opening of the air intake device 2 based on the temperature detected by the temperature sensor.

[0073] The vehicle provided in the embodiment of the present application uses an air intake structure 100 whose base 1 is formed with a first channel 11 and a second channel 12 which are independent of each other. The first end of the first channel 11 is communicated with the interior of the cabin 201 and the air intake of the engine 300 at the same time, and the first end of the second channel 12 is communicated with the cabin 201. When the air intake device 2 at the second end of the first channel 11 is closed and the air intake device 2 at the second end of the second channel 12 is opened, air enters the interior of the cabin 201 through the second channel 12, thereby increasing the pressure inside the cabin 201. At the same time, the suction effect of the air intake of the engine 300 on the interior of the first channel 11 is combined with the suction effect of the air intake of the engine 300 on the interior of the first channel 11, thereby making the pressure inside the cabin 201 greater than the pressure inside the first channel 11. At this time, the air inside the cabin 201 enters the first channel 11 and the second channel 12 in sequence. The air intake of the engine 300 is provided with a heating component 3 at the first end of the second channel 12 and / or at the connection between the first end of the first channel 11 and the cabin 201. In the process of air entering the cabin 201 from the second channel 12 or entering the first channel 11 from the cabin 201, the air can be effectively heated, thereby increasing the temperature of the air entering the engine 300, which is beneficial to increasing the intake temperature of fuel vehicles under low temperature conditions, and at the same time broadening the ambient temperature range in which the engine exhaust gas recirculation can be used. Under low temperature conditions, fresh air with suitable temperature can still be provided to the engine for exhaust gas mixed combustion, thereby improving the fuel evaporation atomization effect and the sufficiency of fuel combustion, thereby achieving the effect of reducing vehicle fuel consumption and reducing vehicle pollutant emissions.

[0074] As shown in FIG2 , the present application further provides an air intake control method, wherein the air intake control method is implemented using the above-described air intake structure 100 and is used to control the air intake of the vehicle described above. The air intake control method includes:

[0075] Detecting the real-time temperature at the air intake of the vehicle's engine;

[0076] When the real-time temperature is lower than the preset temperature, the air intake device 2 at the second end of the first channel 11 is closed or its opening is reduced, and the air intake device 2 at the second end of the second channel 12 is opened or its opening is increased, thereby increasing the flow rate of air entering the interior of the cabin 201 from the second channel 12, or allowing air to enter the interior of the cabin 201 only from the second channel 12, so as to form a low-pressure area inside the first channel 11, so that the air inside the cabin 201 flows toward the interior of the first channel 11 and enters the air intake of the engine 300.

[0077] When the real-time temperature is equal to or higher than the preset temperature, the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are opened, or the opening of the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are increased, so that air can enter the cabin 201 through the first channel 11 and the second channel 12 at the same time. At this time, the pressure in the first channel 11, the second channel 12 and the cabin 201 is basically balanced, and the air flows from the front to the rear of the vehicle. In this process, after the air enters the first channel 11, a part of the air flows directly into the air intake of the engine 300 to provide oxygen for the combustion of the fuel.

[0078] Optionally, the air intake control method provided herein can further adjust the opening of each air intake device 2 based on the temperature within the engine compartment 201 while all air intake devices 2 are open, thereby adjusting the temperature of the air entering the air intake of the engine 300. For example, by increasing the opening of the air intake device 2 at the first passage 11 and decreasing the opening of the air intake device 2 at the second passage 12, the temperature of the air entering the engine 300 can be reduced. By decreasing the opening of the air intake device 2 at the first passage 11 and increasing the opening of the air intake device 2 at the second passage 12, the temperature of the air entering the engine 300 can be increased.

[0079] The intake control method provided in the embodiment of the present application is that the temperature of the air directly entering the first channel 11 through the intake device 2 is relatively low, while the temperature of the air entering the first channel 11 through the engine compartment 201 is relatively high after being heated by the heating component 3. In this way, the opening, closing and opening degree of the intake device 2 at the first channel 11 and the intake device 2 at the second channel 12 are adjusted according to the temperature at the air intake of the engine. The ratio of the air directly entering the first channel 11 and the air entering the first channel 11 through the engine compartment 201 can be adjusted, thereby adjusting the temperature of the air entering the air intake of the engine 300 to ensure the temperature of the air entering the engine 300, which is beneficial to increasing the intake temperature of fuel vehicles under low temperature conditions, and at the same time broadening the ambient temperature range that can be used for engine exhaust gas recirculation. Under low temperature conditions, fresh air with suitable temperature can still be provided to the engine for exhaust gas mixed combustion, thereby improving the fuel evaporation atomization effect and the sufficiency of fuel combustion, thereby achieving the effect of reducing vehicle fuel consumption and reducing vehicle pollutant emissions.

[0080] The present application also provides an air intake control method, wherein the air intake control method is implemented using the above-mentioned air intake structure 100 and is used to control the air intake of the vehicle as described above. The air intake control method includes:

[0081] Detecting the ambient temperature of the vehicle's environment;

[0082] When the ambient temperature is equal to or higher than a preset temperature, the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are opened, or the openings of the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are increased. When the ambient temperature is equal to or higher than the preset temperature, the intake air does not need to be heated. In this case, the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are opened, or the openings of the air intake device 2 at the second end of the first channel 11 and the air intake device 2 at the second end of the second channel 12 are increased, and the air inhaled by the engine 300 is unheated air.

[0083] When the ambient temperature is lower than a preset temperature, the air intake device 2 at the second end of the first channel 11 is closed or its opening is reduced, and the air intake device 2 at the second end of the second channel 12 is opened or its opening is increased. Closing the air intake device 2 at the second end of the first channel 11 or reducing its opening causes the air intake port of the engine 300 to be within the semi-enclosed space formed by the first channel 11. Continuous intake of air creates a low-pressure area in this area. When the air intake device 2 at the second end of the second channel 12 is opened or its opening is increased, a high-pressure area will be formed in the cabin when the vehicle is driving or the cooling fan inside the vehicle is blowing. After the air in the low-temperature environment passes through the air intake device 2 at the second end of the second channel 12, the air flows through the heating component 3 at the first end of the second channel 12 and is heated by the heating component 3. Then, the air is heated by the engine 300 in the cabin, that is, the surface of the engine 300 and the exhaust pipe of the engine 300 heat the air. Then, the air passes through the heating component 3 at the second end of the first channel 11 and is heated again by the heating component 3. Then, the air flows to the inside of the first channel 11 and enters the air intake of the engine 300. At this time, the air in the low-temperature environment has been heated three times, and the temperature will rise significantly.
