[0002] During engine operation, the friction between the piston ring and the cylinder bore and the combustion of fuel generate a lot of heat.

The temperature of the upper part of the inner wall of the cylinder may exceed 370°C, while the temperature of the lower part may be less than 150°C. This temperature gradient causes a significant temperature difference in the cylinder block, affecting the effective dissipation of internal heat. At the same time, the high temperature environment causes the lubricating oil to oxidize and form carbon deposits, which in turn causes abnormal combustion, which may cause problems such as cylinder block deformation, cylinder gasket damage and machine wear.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0033] As mentioned in the background, during the operation of the engine, a large amount of heat is generated by the friction between the piston ring and the cylinder bore and the combustion of the fuel. Although the coolant and air cool the periphery of the cylinder and the engine oil also takes away some of the heat, the temperature of the inner wall of the cylinder bore is still high. The temperature of the upper part of the inner wall of the cylinder may exceed 370°C, while the temperature of the lower part may be lower than 150°C. This temperature gradient causes a significant temperature difference in the cylinder block, affecting the effective dissipation of internal heat. At the same time, the high temperature environment causes the lubricating oil to oxidize and form carbon deposits, which in turn causes abnormal combustion, which may cause problems such as cylinder block deformation, cylinder gasket damage and mechanical wear. In order to better solve this problem, researchers proposed an engine cooling system. The engine cooling system can make the cooling temperature of the upper part and the lower part of the cylinder block of the engine uniform, thereby reducing the temperature gradient in the cylinder block and ensuring the stable operation of the engine.

[0034] like Figure 1 As shown, Figure 1 This is a schematic diagram of the module of the engine cooling system in one embodiment of the present application. The engine cooling system includes: a first cylinder water jacket 110, a second cylinder water jacket 120, a cylinder head water jacket 130 and a drive element 200, wherein the coolant entering the first cylinder water jacket 110 is used to cool the upper side of the cylinder block, the coolant entering the second cylinder water jacket 120 is used to cool the lower part of the cylinder block, and the coolant entering the cylinder head water jacket 130 is used to cool the cylinder head. The researchers intend to significantly reduce the temperature gradient between the upper and lower parts of the cylinder block through the proposed engine cooling system, so that the engine can run stably under the condition of uniform temperature distribution.

[0035] Specifically, the first cylinder block water jacket 110 is arranged at the upper part of the cylinder block, and the coolant in the first cylinder block water jacket 110 is used to cool the upper part of the cylinder block; the second cylinder block water jacket 120 is arranged at the lower part of the cylinder block, and the coolant in the second cylinder block water jacket 120 is used to cool the lower part of the cylinder block; the cylinder head water jacket 130 is arranged at the cylinder head, and the coolant in the cylinder head water jacket 130 is used to cool the cylinder head, and the outlet of the cylinder head water jacket 130 is connected with the second cylinder block water jacket 120; the driving element 200 is used to transport the coolant to the first cylinder block water jacket 110 and the cylinder head water jacket 130 respectively, and the coolant discharged from the first cylinder block water jacket 110 and the second cylinder block water jacket 120 is circulated and transported to the driving element 200, and the driving element 200 can be a water pump.

[0036] In this embodiment, when the engine is working, the driving element 200 delivers the coolant to the first cylinder water jacket 110 and the cylinder head water jacket 130 respectively. After the coolant flows out of the driving element 200, it enters the first cylinder water jacket 110 and the cylinder head water jacket 130 respectively. After the coolant enters the first cylinder water jacket 110, it exchanges heat with the upper part of the cylinder body, thereby reducing the temperature of the upper part of the cylinder body; at the same time, the coolant enters the cylinder head water jacket 130, exchanges heat with the cylinder head, reduces the temperature of the cylinder head and prevents the cylinder head from overheating. The coolant after absorbing heat flows out of the cylinder head water jacket 130, enters the second cylinder water jacket 120, exchanges heat with the lower part of the cylinder body, so as to increase the temperature of the lower part of the cylinder body, reduce the temperature difference between the upper part and the lower part of the cylinder body, and shorten the warm-up time of the lower part of the cylinder body. By means of the first cylinder water jacket 110 and the second cylinder water jacket 120 in the engine cooling system of this embodiment, zoned cooling of the cylinder block is achieved, thereby significantly reducing the temperature gradient between the upper and lower parts of the cylinder block, effectively avoiding problems such as cylinder block deformation, cylinder gasket damage and mechanical wear, and ensuring stable operation of the engine.

[0037] Another function of the scheme of this embodiment is that in the existing engine cooling system, the flow path of the coolant is usually through the cylinder block water jacket to the cylinder head water jacket 130, and it needs to be circulated through the small holes on the cylinder gasket. However, due to the certain flow resistance of the small holes of the cylinder gasket, the flow of the coolant may be restricted, thereby affecting the cooling efficiency. In this embodiment, the coolant is directly delivered to the first cylinder block water jacket 110 and the cylinder head water jacket 130 through the driving element 200, and the coolant after absorbing heat is further delivered to the second cylinder block water jacket 120 through the cylinder head water jacket 130. This effectively avoids the flow resistance problem caused by the small holes of the cylinder gasket in the traditional scheme and optimizes the flow path of the coolant.

[0038] In one embodiment, see Figure 2As shown, the engine cooling system also includes a thermostat module 300 and a flow regulating valve 410. The thermostat module 300 is used to detect the temperature of the engine. The flow regulating valve 410 is connected to the drive element 200, the first cylinder block water jacket 110 and the cylinder head water jacket 130. The flow regulating valve 410 adjusts the flow ratio of the coolant flowing to the first cylinder block water jacket 110 and the cylinder head water jacket 130 according to the engine temperature detected by the thermostat module 300.

[0039] In this embodiment, the temperature of the engine can be monitored in real time through the thermostat module 300, and the temperature data can be transmitted to the flow control valve 410. The flow control valve 410 dynamically adjusts the flow distribution ratio of the coolant between the first cylinder water jacket 110 and the cylinder head water jacket 130 according to the temperature information transmitted by the thermostat module 300. When the temperature of the upper part of the cylinder block is high, the flow control valve 410 adjusts the flow ratio of the coolant flowing to the first cylinder water jacket 110 to increase, so that more coolant flows through the first cylinder water jacket 110 and exchanges heat with the upper part of the cylinder block, thereby effectively reducing the temperature of the upper part of the cylinder block. When the temperature of the cylinder head is high, the flow control valve 410 adjusts the flow ratio of the coolant flowing to the cylinder head water jacket 130 to increase, so that more coolant flows through the cylinder head water jacket 130 and exchanges heat with the cylinder head, thereby reducing the temperature of the cylinder head.

[0040] The flow rate of the coolant is dynamically adjusted by the thermostat module 300 and the flow control valve 410 in this embodiment, so that the coolant can be accurately controlled according to the actual temperature distribution of the cylinder block and the cylinder head in the engine, thereby ensuring that the temperature of the upper part of the cylinder block, the lower part of the cylinder block and the cylinder head is more uniform.

[0041] In one embodiment, see Figure 2 As shown, a first throttle valve 420 is provided at the outlet of the first cylinder water jacket 110 , and the first throttle valve 420 is electrically connected to the thermostat module 300 . The first throttle valve 420 adjusts the flow rate of the coolant flowing out of the first cylinder water jacket 110 according to the temperature value of the thermostat module 300 .

[0042] In this embodiment, when the engine is initially started, the thermostat module 300 detects that the temperature of the upper part of the cylinder block is low. At this time, the cylinder block is preheated by controlling the flow rate of the coolant to shorten the warm-up time. Specifically, the thermostat module 300 controls the opening of the first throttle valve 420 according to the detected temperature signal. When the speed of the coolant flowing out of the first cylinder water jacket 110 is too fast and may prolong the warm-up time of the cylinder block, the first throttle valve 420 reduces the flow rate according to the temperature signal of the thermostat module 300, thereby increasing the residence time of the coolant in the first cylinder water jacket 110, so that the cylinder block can complete the warm-up process more efficiently. When the temperature of the upper part of the cylinder block is high, the thermostat module 300 sends an adjustment signal to the first throttle valve 420, and the first throttle valve 420 increases the flow rate of the coolant to discharge, thereby increasing the flow rate of the coolant in the first cylinder water jacket 110, accelerating the heat exchange process of the upper part of the cylinder block, and achieving rapid cooling. By arranging the first throttle valve 420 at the outlet of the first cylinder water jacket 110, dynamic regulation of the coolant flow at the outlet of the first cylinder water jacket 110 is achieved, thereby effectively shortening the warm-up time when the engine is started, and dynamically adjusting the cooling speed of the upper part of the cylinder block during engine operation, thereby significantly reducing the temperature gradient of the cylinder block, ensuring uniform heat distribution, and improving the stability of the overall operation of the engine.

[0043] In one embodiment, see Figure 2 As shown, the engine cooling system further includes a bypass channel 140 , which is communicated with the outlet of the cylinder head water jacket 130 and is used to transport the coolant to the heater core 510 for heat exchange.

[0044] In this embodiment, the bypass channel 140 in the engine cooling system is connected to the outlet of the cylinder head water jacket 130. After the coolant absorbs heat from the cylinder head water jacket 130, the bypass channel 140 guides the coolant to the heater core 510 for heat exchange. The coolant that has absorbed the heat of the cylinder head is introduced into the heater core 510 through the bypass channel 140, so that the heater core 510 can use the heat carried by the coolant, thereby realizing the secondary utilization of the heat. The heat in the cylinder head water jacket 130 is introduced into the heater core 510 through the bypass channel 140 in this embodiment, which effectively recovers the heat energy in the coolant and improves the energy utilization efficiency.

[0045] In one embodiment, see Figure 2 As shown, a second throttle valve 430 is also provided at the outlet of the bypass channel 140 , and the second throttle valve 430 is electrically connected to the thermostat module 300 , and the second throttle valve 430 adjusts the flow of the coolant in the bypass channel 140 to the heater core 510 according to the temperature value of the thermostat module 300 .

[0046] In this embodiment, when the engine is initially started, the thermostat module 300 detects that the temperature of the cylinder head is low. At this time, it is necessary to reduce the transfer of coolant to the heater core 510 to avoid excessive heat loss. To this end, the second throttle valve 430 adjusts the opening according to the temperature signal of the thermostat module 300, and reduces the flow of coolant flowing through the bypass channel 140 into the heater core 510, thereby maintaining the heat concentration of the cylinder head and shortening the warm-up time of the engine. When the temperature of the cylinder head is high, the thermostat module 300 sends an adjustment signal to the second throttle valve 430, and the second throttle valve 430 increases the opening, so that more coolant enters the heater core 510 through the bypass channel 140, fully exchanges heat with the heater core 510, and improves the thermal energy utilization efficiency of the heater core 510. By setting a second throttle valve 430 at the outlet of the bypass channel 140 and combining the real-time monitoring and regulation of the thermostat module 300, dynamic regulation of the flow of coolant entering the heater core 510 is achieved, which not only meets the cooling requirements of the engine under different operating conditions, but also realizes the effective reuse of the coolant heat energy.

[0047] In one embodiment, see Figure 2 As shown, the engine cooling system further includes a radiator 520 , which is in communication with the driving element 200 and is used to reduce the temperature of the coolant.

[0048] In this embodiment, the radiator 520 is connected to the driving element 200. When the coolant absorbs heat from the engine cooling system and flows through the radiator 520, the radiator 520 exchanges heat with the outside air to reduce the temperature of the coolant. After cooling through the radiator 520, the coolant enters the driving element 200 again and is transported to the first cylinder water jacket 110 and the cylinder head water jacket 130 to further cool the upper part of the cylinder block and the cylinder head. By providing the radiator 520 in the engine cooling system, the temperature of the coolant during the circulation process is effectively controlled to prevent the coolant temperature from being too high and affecting the cooling effect.

[0049] In one embodiment, see Figure 3 As shown, the outlet of the cylinder head water jacket 130 is also connected to the engine oil cooler 530 for heat exchange between the coolant discharged from the cylinder head water jacket 130 and the engine oil.

[0050] In this embodiment, the outlet of the cylinder head water jacket 130 is connected to the oil cooler 530, and the coolant discharged from the cylinder head water jacket 130 can enter the oil cooler 530 and perform heat exchange with the oil. The coolant absorbs the heat of the oil in the oil cooler 530, thereby reducing the temperature of the oil and preventing the lubrication performance from being reduced and the oxidation rate from being accelerated due to overheating of the oil. By connecting the cylinder head water jacket 130 with the oil cooler 530, the overall heat dissipation capacity of the engine cooling system and the temperature control effect of the oil are further enhanced while the heat of the coolant is reused.

[0051] In one embodiment, see Figure 3 As shown, the cylinder head water jacket 130 and the oil cooler 530 are also connected to the supercharger 540 through a parallel pipeline. Part of the coolant discharged from the cylinder head water jacket 130 flows through the supercharger 540 and merges with the coolant directly flowing out of the cylinder head water jacket 130 before flowing into the oil cooler 530.

[0052] In this embodiment, the cylinder head water jacket 130 and the oil cooler 530 are connected to the supercharger 540 through a parallel pipeline. After part of the coolant is discharged from the cylinder head water jacket 130, it flows through the supercharger 540 and exchanges heat with the turbine and related high-temperature components in the supercharger 540, thereby reducing the working temperature of the turbine and improving the heat dissipation capacity of the supercharger 540. After the coolant completes the heat exchange in the supercharger 540, it merges with the coolant directly flowing out of the cylinder head water jacket 130, flows into the oil cooler 530 together, and further exchanges heat with the oil in the oil cooler 530, so as to achieve precise control of the oil temperature. By setting a parallel pipeline between the cylinder head water jacket 130 and the oil cooler 530 and connecting the supercharger 540, the coolant cools the turbine components and the oil of the supercharger 540 at the same time during the circulation process, thereby enhancing the overall thermal management capability of the cooling system.

[0053] In one embodiment, see Figure 3 As shown, the cylinder head water jacket 130 is also in communication with the exhaust gas recirculation cooler 550 for heat exchange between the coolant discharged from the cylinder head water jacket 130 and the exhaust gas recirculation cooler 550 .

[0054] In this embodiment, the cylinder head water jacket 130 is connected to the exhaust gas recirculation (EGR) cooler 550. After the coolant is discharged from the cylinder head water jacket 130, it flows into the exhaust gas recirculation cooler 550 to exchange heat with the exhaust gas to reduce the temperature of the exhaust gas. By transferring the heat absorbed in the cylinder head water jacket 130 to the exhaust gas recirculation cooler 550, the heat load of the components caused by high temperature during the exhaust gas recirculation process can be effectively reduced, and the temperature of the exhaust gas recirculation can be reduced, thereby improving the efficiency of the exhaust gas recirculation.

[0055] The application also proposes a car, wherein the car comprises the above engine cooling system.

[0056] In this embodiment, by using the above-mentioned engine cooling system in the automobile, zoned cooling of the upper and lower parts of the cylinder block is achieved, which effectively reduces the temperature gradient inside the cylinder block, avoids problems such as cylinder block deformation, cylinder gasket damage and mechanical wear caused by temperature differences, thereby ensuring the stable operation of the engine.

[0057] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
