Description

Technical Field

[0001] This invention belongs to the field of vehicle cooling technology, and particularly relates to an engine cooling system, control method and storage medium. Background Technology

[0002] EGR (exhaust gas recirculation) systems are widely used in vehicles as a solution to reduce vehicle exhaust pollution.

[0003] In existing technologies, additional energy and heating devices are often used to heat the engine coolant, without fully utilizing the heat from the engine's own combustion exhaust gases to heat the coolant. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] This invention provides an engine cooling system for a vehicle having an engine, the engine having a first intake manifold, a first exhaust manifold, and a water tank, the system comprising: A cooler, which is connected to the first exhaust pipe and the cooler is connected to the water tank; A first pipeline is connected to the cooler, and a first valve is provided on the first pipeline; The second pipeline is connected to the cooler and is equipped with a second valve. The second pipeline is also connected to the first air intake pipe.

[0006] The engine cooling system of the present invention is provided with a first valve and a second valve. By adjusting the opening of the first valve and the second valve, as much high-temperature exhaust gas as possible is used to heat the coolant using the cooler, and then the coolant is used to heat the engine. This achieves the purpose of quickly heating the coolant by utilizing the heat of the exhaust gas discharged from the engine and the existing cooler on the engine, without the need for an additional heat source and heat exchanger, thereby achieving the purpose of quickly warming up the engine.

[0007] In some embodiments, it also includes: A turbocharger, the turbocharger including a compressor and a turbine connected to the compressor, the turbine having a second exhaust pipe connected to a first pipeline; An intercooler, which is connected to the compressor; A mixer, which is connected to the intercooler, the mixer is connected to the second pipeline, and the mixer is connected to the first intake pipe.

[0008] By incorporating a turbocharger, the energy of the exhaust gas is used to compress the intake air, thereby significantly increasing power and torque without increasing engine displacement. An intercooler is used to cool the high-temperature gas discharged from the compressor. A mixer is used to mix the gas discharged from the intercooler with the exhaust gas passing through the second valve before it is discharged into the engine through the first intake manifold.

[0009] The present invention also provides a control method for an engine cooling system, applied to the aforementioned engine cooling system, the method comprising: Obtain the operating status of the vehicle; When the vehicle is in the first operating state, the engine cooling system is set to operate in the first mode; When the vehicle is in the second operating state, the engine cooling system is set to operate in the second mode; The first mode includes: Obtain the temperature of the coolant in the water tank; When the temperature of the coolant in the water tank is lower than the preset temperature, the first valve is fully opened and the second valve is closed. When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, the first valve is closed and the second valve is closed.

[0010] The control method of this invention first acquires the vehicle's operating state. When the vehicle's operating state is in a first state, the temperature of the coolant in the water tank is acquired. When the temperature of the coolant in the water tank is lower than a preset temperature, it is considered that the coolant temperature is low and needs to be heated. At this time, the first valve is opened, and the high-temperature exhaust gas from the engine is used to heat the coolant through the cooler. When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, it is considered that the coolant temperature is high and does not need to be heated. At this time, the first valve is closed.

[0011] In some embodiments, after the first valve is fully opened and the second valve is closed when the temperature of the coolant in the water tank is lower than a preset temperature, the method further includes: When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, the first valve is closed.

[0012] The above solution has the following technical effects: After the high-temperature exhaust gas from the engine heats the coolant through the cooler, the coolant temperature gradually rises. When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, it is considered that the coolant heating is complete. At this time, the first valve is closed, and the use of the high-temperature exhaust gas from the engine to heat the coolant through the cooler is stopped.

[0013] In some embodiments, the second mode includes: Obtain the temperature of the coolant in the water tank; When the temperature of the coolant in the water tank is lower than the preset temperature, the second valve is fully opened; Obtain the flow rate of the gas flowing through the second valve; When the flow rate of gas flowing through the second valve is equal to the preset flow rate, the first valve is opened to the preset opening degree.

[0014] The above solution has the following technical effects: When the vehicle is in the second operating state, the temperature of the coolant in the water tank is obtained. When the temperature of the coolant in the water tank is lower than the preset temperature, it is considered that the coolant temperature is low and needs to be heated. At this time, the second valve is opened. On the one hand, this ensures that the exhaust gas enters the combustion chamber of the engine to participate in normal combustion. On the other hand, the high-temperature exhaust gas uses the cooler to heat the coolant. Then, the flow rate of the gas flowing through the second valve is obtained. When the flow rate of the gas flowing through the second valve is equal to the preset flow rate, it is considered that the exhaust gas can enter the combustion chamber of the engine to participate in normal combustion. At this time, the first valve is opened to the preset opening degree, so that as much exhaust gas as possible flows through the cooler, accelerating the speed at which the high-temperature exhaust gas heats the coolant in the cooler, thereby achieving the purpose of rapid engine warm-up.

[0015] In some embodiments, after obtaining the flow rate of the gas flowing through the second valve, the method further includes: When the flow rate of gas flowing through the second valve is less than the preset flow rate, the first valve is closed.

[0016] The above solution has the following technical effects: when the flow rate of the gas flowing through the second valve is less than the preset flow rate, it is considered that the exhaust gas cannot be guaranteed to enter the combustion chamber of the engine to participate in normal combustion. At this time, the first valve needs to be closed to ensure that the exhaust gas enters the combustion chamber of the engine to participate in normal combustion.

[0017] In some embodiments, after opening the first valve to a preset opening degree when the flow rate of gas flowing through the second valve is equal to a preset flow rate, the method further includes: When the flow rate of gas through the second valve is less than the preset flow rate, the opening degree of the first valve is reduced.

[0018] The above solution has the following technical effects: opening the first valve to the preset opening degree can accelerate the speed at which the high-temperature exhaust gas discharged from the engine heats the coolant in the cooler. However, when the flow rate of the gas flowing through the second valve is less than the preset flow rate, it is considered that the exhaust gas cannot be guaranteed to enter the combustion chamber of the engine to participate in normal combustion. At this time, it is necessary to reduce the opening degree of the first valve to prioritize the exhaust gas entering the combustion chamber of the engine to participate in normal combustion.

[0019] In some embodiments, after obtaining the temperature of the coolant in the water tank, the method further includes: when the temperature of the coolant in the water tank is greater than or equal to the preset temperature, closing the first valve and fully opening the second valve.

[0020] The above solution has the following technical effects: when the temperature of the coolant in the water tank is greater than or equal to the preset temperature, it is considered that the coolant temperature is high and there is no need to heat the coolant. At this time, the first valve is closed. The second valve is opened to ensure that the exhaust gas enters the engine's combustion chamber to participate in normal combustion.

[0021] In some embodiments, obtaining the operating status of the vehicle includes: Obtain the speed of the vehicle; Obtain the engine speed; and Get the throttle opening.

[0022] By measuring the vehicle's speed, engine speed, and throttle position, the vehicle's operating status can be accurately determined.

[0023] The present invention also provides a storage medium storing a program or instructions that, when executed by a processor, implement the steps of the method described above. Attached Figure Description

Detailed Implementation

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0028] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. The terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0029] like Figure 1 As shown, an engine cooling system is provided for a vehicle having an engine 1, the engine 1 having a first intake pipe 11, a first exhaust pipe 13, and a water tank 12. The engine 1 cooling system includes a cooler 2, a first pipe, and a second pipe. The cooler 2 is connected to the first exhaust pipe 13 and the water tank 12. The first pipe is connected to the cooler 2 and is equipped with a first valve 3. The second pipe is connected to the cooler 2 and is equipped with a second valve 4. The second pipe is also connected to the first intake pipe 11.

[0030] In this embodiment, the engine 1 cooling system is equipped with a first valve 3 and a second valve 4. By adjusting the opening of the first valve 3 and the second valve 4, as much high-temperature exhaust gas as possible is used to heat the coolant using the cooler 2, and then the coolant is used to heat the engine 1. This achieves the purpose of quickly heating the coolant by utilizing the heat from the exhaust gas discharged from the engine 1 and the existing cooler 2 on the engine 1, without the need for an additional heat source and heat exchanger.

[0031] Specifically, valve 3 is an EGR bypass valve. Valve 4 is an EGR valve. Cooler 2 is an EGR cooler.

[0032] Optionally, the coolant is water.

[0033] In some embodiments, the engine 1 cooling system further includes a turbocharger 5, an intercooler 6, and a mixer 7. The turbocharger 5 includes a compressor 51 and a turbine 52 connected to the compressor 51. The turbine 52 has a second exhaust pipe 54 connected to a first conduit. The intercooler 6 is connected to the compressor 51. The mixer 7 is connected to the intercooler 6, the second conduit, and the first intake pipe 11.

[0034] By incorporating a turbocharger 5, the energy of the exhaust gas from engine 1 is used to compress the intake air, thereby significantly increasing power and torque without increasing the displacement of engine 1. An intercooler 6 is incorporated to cool the high-temperature gas discharged from compressor 51. A mixer 7 is used to mix the gas discharged from intercooler 6 with the exhaust gas passing through the second valve 4, and then discharges the mixture into engine 1 through the first intake manifold 11.

[0035] Specifically, mixer 7 is an EGR mixer.

[0036] In some embodiments, the engine 1 cooling system further includes a temperature sensor 9. The temperature sensor 9 is used to detect the temperature of the coolant in the water tank 12.

[0037] In some embodiments, the engine 1 cooling system further includes a controller 8. The controller 8 is electrically connected to the first valve 3, the second valve 4, and the temperature sensor 9. The controller 8 is capable of controlling the opening degree of the first valve 3 and the second valve 4.

[0038] Specifically, the controller is an ECU (Electronic Control Unit).

[0039] like Figure 2 As shown, a control method for an engine cooling system, applied to the aforementioned engine cooling system, includes the following steps: Step S10: Obtain the vehicle's operating status.

[0040] Step S20: When the vehicle is in the first operating state, the engine cooling system is set to operate in the first mode.

[0041] Step S30: When the vehicle is in the second operating state, the engine cooling system is set to operate in the second mode.

[0042] like Figure 3 As shown, the first mode includes the following steps: Step S201: Obtain the temperature of the coolant in the water tank.

[0043] Step S202: When the temperature of the coolant in the water tank is lower than the preset temperature, the first valve is fully opened and the second valve is closed.

[0044] Step S203: When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, the first valve is closed and the second valve is closed.

[0045] The control method of the engine cooling system in this embodiment first acquires the vehicle's operating state. When the vehicle's operating state is in the first state, the temperature of the coolant in the water tank is acquired. When the temperature of the coolant in the water tank is lower than a preset temperature, it is considered that the coolant temperature is low and needs to be heated. At this time, the first valve is opened, and the high-temperature exhaust gas from the engine is used to heat the coolant through the cooler. When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, it is considered that the coolant temperature is high and does not need to be heated. At this time, the first valve is closed.

[0046] For example, the first state could be an idling state. The second state could be a running state.

[0047] like Figure 4 As shown, step S10: Obtaining the vehicle's operating status includes the following steps: Step S101: Obtain the speed of the vehicle.

[0048] Step S102: Obtain the engine speed.

[0049] Step S103: Obtain the throttle opening.

[0050] By measuring the vehicle's speed, engine speed, and throttle position, the vehicle's operating status can be accurately determined.

[0051] Specifically, when the vehicle speed is 0, the engine speed is at idle speed, and the throttle opening is 0, it is in an idling state. When the vehicle speed is not 0, the engine speed is not at idle speed, or the throttle opening is not 0, it is in an operating state.

[0052] When the vehicle is idling, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered low and requires heating. The ECU then controls the first valve to fully open (i.e., the first valve opening is 100%), and the high-temperature exhaust gas from the engine uses the cooler to heat the coolant. Since the vehicle is idling at this time, exhaust gas does not need to enter the engine's combustion chamber for combustion, so the ECU controls the second valve to close.

[0053] When the vehicle is idling, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is greater than or equal to a preset temperature (e.g., 70°C), it is considered that the coolant temperature is high and does not require heating. The ECU then controls the first valve to close, allowing exhaust gases to directly enter the turbine. Since the vehicle is idling at this time, exhaust gases do not need to enter the engine's combustion chamber for combustion, so the ECU controls the second valve to close.

[0054] like Figure 5 As shown, in step S202: when the temperature of the coolant in the water tank is lower than the preset temperature, the first valve is fully opened and the second valve is closed. The following steps are also included: Step S204: When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, close the first valve.

[0055] After the high-temperature exhaust gas from the engine heats the coolant through the cooler, the coolant temperature gradually rises. When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, the coolant is considered to have finished heating. At this point, the first valve is closed, and the use of the high-temperature exhaust gas from the engine to heat the coolant through the cooler is stopped.

[0056] When the vehicle is idling, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered low and requires heating. The ECU controls the first valve to fully open (i.e., the first valve opening is 100%), and the high-temperature exhaust gas from the engine uses the cooler to heat the coolant. Because the high-temperature exhaust gas heats the coolant, its temperature rises. When the coolant temperature in the radiator is greater than or equal to the preset temperature, the first valve closes, and it is no longer necessary to use exhaust gas to heat the coolant.

[0057] like Figure 6 As shown, the second mode includes the following steps: Step S301: Obtain the temperature of the coolant in the water tank; Step S302: When the temperature of the coolant in the water tank is lower than the preset temperature, the second valve is fully opened; Step S303: Obtain the flow rate of the gas flowing through the second valve; Step S304: When the flow rate of the gas flowing through the second valve is equal to the preset flow rate, open the first valve to the preset opening degree.

[0058] When the vehicle is in the second operating state, the temperature of the coolant in the water tank is acquired. If the coolant temperature is lower than the preset temperature, it is considered that the coolant temperature is too low and needs to be heated. At this time, the second valve is opened. This ensures that exhaust gas enters the engine's combustion chamber to participate in normal combustion, and the high-temperature exhaust gas uses the cooler to heat the coolant. Then, the flow rate of the gas flowing through the second valve is acquired. When the flow rate of the gas flowing through the second valve equals the preset flow rate, it is considered that the exhaust gas can enter the engine's combustion chamber to participate in normal combustion. At this time, the first valve is opened to the preset opening degree, allowing as much exhaust gas as possible to flow through the cooler, accelerating the rate at which the high-temperature exhaust gas heats the coolant in the cooler, thereby achieving the purpose of quickly warming up the engine.

[0059] When the vehicle is running, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered low and requires heating. The ECU then controls the second valve to fully open. This ensures that exhaust gases enter the engine's combustion chamber for normal combustion, and the high-temperature exhaust gases are used to heat the coolant via the cooler. The ECU also monitors the flow rate of gas passing through the second valve. When this flow rate equals a preset flow rate (e.g., 400 m³ / h), the first valve opens to a preset opening degree (e.g., 70%), allowing as much exhaust gas as possible to flow through the cooler. This accelerates the heating of the coolant by the high-temperature exhaust gases, thus achieving rapid engine warm-up.

[0060] like Figure 7 As shown, after obtaining the flow rate of the gas flowing through the second valve in step S303, the following steps are also included: Step S305: When the flow rate of gas flowing through the second valve is less than the preset flow rate, the first valve is closed.

[0061] When the flow rate of gas through the second valve is less than the preset flow rate, it is considered that the exhaust gas cannot be guaranteed to enter the combustion chamber of the engine to participate in normal combustion. At this time, the first valve needs to be closed to ensure that the exhaust gas enters the combustion chamber of the engine to participate in normal combustion.

[0062] When the vehicle is running, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered low and requires heating. The ECU controls the second valve to fully open, ensuring that exhaust gases enter the engine's combustion chamber for normal combustion, while the high-temperature exhaust gases use the cooler to heat the coolant. The ECU also monitors the flow rate of gas passing through the second valve. If the flow rate is lower than a preset rate, it is considered insufficient for exhaust gases to enter the engine's combustion chamber for normal combustion. In this case, the first valve needs to be closed to prioritize exhaust gas entry into the engine's combustion chamber for proper combustion.

[0063] like Figure 8 As shown, in step S304: when the flow rate of the gas flowing through the second valve is equal to the preset flow rate, after opening the first valve to the preset opening degree, the following steps are also included: Step S306: When the flow rate of gas flowing through the second valve is less than the preset flow rate, reduce the opening of the first valve.

[0064] Opening the first valve to a preset opening degree can accelerate the speed at which the high-temperature exhaust gas discharged from the engine heats the coolant in the cooler. However, when the flow rate of the gas flowing through the second valve is less than the preset flow rate, it is considered that the exhaust gas cannot be guaranteed to enter the combustion chamber of the engine to participate in normal combustion. At this time, it is necessary to reduce the opening degree of the first valve to prioritize ensuring that the exhaust gas enters the combustion chamber of the engine to participate in normal combustion.

[0065] When the vehicle is running, the ECU obtains the temperature of the coolant in the radiator via a temperature sensor. When the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered low and requires heating. The ECU then controls the second valve to fully open. This ensures that exhaust gases enter the engine's combustion chamber for normal combustion, and the high-temperature exhaust gases are used to heat the coolant via the cooler. The ECU also monitors the flow rate of gas passing through the second valve. When this flow rate equals a preset flow rate (e.g., 400 m³ / h), the first valve opens to a preset opening degree (e.g., 70%), allowing as much exhaust gas as possible to flow through the cooler. This accelerates the heating of the coolant by the high-temperature exhaust gases, thus achieving rapid engine warm-up. After the first valve is opened to a preset opening degree (e.g., 70%), the flow rate of the gas flowing through the second valve continues to be acquired. When the flow rate of the gas flowing through the second valve is less than the preset flow rate (e.g., 400 m³ / h), it is considered that the exhaust gas cannot be guaranteed to enter the combustion chamber of the engine to participate in normal combustion. At this time, the opening degree of the first valve needs to be reduced to ensure that the exhaust gas enters the combustion chamber of the engine to participate in normal combustion.

[0066] The specific steps for reducing the opening of the first valve are as follows: When the flow rate of gas flowing through the second valve is detected to be less than the preset flow rate (e.g., 400 m³ / h), the ECU controls the opening of the first valve to decrease by 10% (i.e., the opening of the first valve decreases from 70% to 60%), and continues to acquire the flow rate of gas flowing through the second valve. When the flow rate of gas flowing through the second valve is equal to the preset flow rate (e.g., 400 m³ / h), the ECU controls the opening of the first valve to remain at 60%. When the flow rate of gas flowing through the second valve is less than the preset flow rate (e.g., 400 m³ / h), the ECU controls the opening of the first valve to decrease by another 10% (i.e., the opening of the first valve decreases from 60% to 50%), and continues to acquire the flow rate of gas flowing through the second valve. If the flow rate of gas flowing through the second valve is still less than the preset flow rate (e.g., 400 m³ / h), the ECU controls the opening of the first valve to decrease by another 10% (i.e., the opening of the first valve decreases from 50% to 40%), and repeats the above steps until the flow rate of gas flowing through the second valve is equal to the preset flow rate (e.g., 400 m³ / h) or the opening of the first valve decreases to 0% (i.e., the first valve is closed).

[0067] like Figure 9 As shown, after obtaining the temperature of the coolant in the water tank in step S301, the following steps are also included: Step S307: When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, the first valve is closed and the second valve is fully opened.

[0068] When the temperature of the coolant in the water tank is greater than or equal to the preset temperature, it is considered that the coolant temperature is high and no further heating is needed. At this time, the first valve is closed. The second valve is opened to ensure that exhaust gas enters the engine's combustion chamber and participates in normal combustion.

[0069] When the vehicle is running, the ECU obtains the temperature of the coolant in the radiator through a temperature sensor. If the coolant temperature is lower than a preset temperature (e.g., 70°C), it is considered that the coolant temperature is too high and heating is unnecessary. At this time, the first valve is closed, and the second valve is opened to ensure that exhaust gases enter the engine's combustion chamber and participate in normal combustion.
