[0036] The term "plurality" used in the present application refers to two or more (including two).

[0037] First of all, it should be pointed out that the engine, as the core component of vehicle driving, provides power for the vehicle, that is, converts a certain type of energy into mechanical energy. For the vehicle, the engine can provide the required power for the vehicle's driving, and determines the vehicle's power, economy, stability and environmental protection. The engine equipped with a water-to-air intercooler assembly can perform better and more significantly in power, economy, stability and environmental protection.

[0038] Engines with water-to-air intercooler assemblies combine the advantages of water cooling and air cooling to improve engine efficiency and performance, especially in hybrid vehicle applications. Its advantages are mainly reflected in the following aspects:

[0039] 1. Improve thermal efficiency: By reducing the intake temperature after supercharging, the water-to-air intercooler assembly can effectively increase the density of air entering the cylinder, thereby increasing the amount of oxygen per combustion and improving the combustion efficiency of the fuel. This is crucial for hybrid engines that pursue high thermal efficiency, helping to improve fuel economy and reduce emissions.

[0040] 2. Enhanced stability: Compared with systems that rely solely on air cooling, the water-to-air intercooler assembly provides a more stable cooling effect, especially at low speeds or in high temperature environments. It can maintain the consistency of the engine operating temperature, reduce performance degradation caused by temperature fluctuations, and extend engine life.

[0041] 3. Optimize power output: Through more effective temperature management, hybrid-specific engines can provide stronger and smoother power output when needed. This is critical to ensuring the responsiveness of the power system and driving experience when hybrid vehicles switch between pure electric drive and hybrid drive modes under different working conditions.

[0042] 4. Strong adaptability: When designing hybrid vehicles, the coordinated work of the electric motor and the engine must be considered. The water-to-air intercooler assembly helps the engine maintain optimal working conditions under various loads and operating conditions, and can maintain a good balance of efficiency and performance whether it is low-speed urban driving or high-speed cruising.

[0043] 5. Energy saving and emission reduction: The efficient cooling system supports the engine to run at a higher compression ratio while reducing the risk of knock, which is crucial for achieving low fuel consumption and meeting strict emission standards (such as National VI b), and is in line with the design concept of hybrid vehicles pursuing environmental protection and energy saving.

[0044] However, the space inside the vehicle's cabin is limited, especially for hybrid vehicles. The drive motor also needs to occupy a certain amount of cabin space, and the intercooler assembly takes up a large amount of space, making it difficult to arrange. If the intercooler assembly is not arranged properly, the cooling effect of the intercooler assembly will be poor, the cooling stability will be low, and it will be difficult to disassemble and assemble, and the maintenance convenience will be low.

[0045] Based on this, the present application proposes an engine in which the intercooler assembly can be arranged overhead, which reduces the difficulty of disassembly and assembly and improves the convenience of maintenance. At the same time, the intercooler assembly occupies less space, has lower layout difficulty, has a reasonable layout position, and has a stable and reliable cooling effect.

[0046] Reference below Figure 1-Figure 4 An engine 100 and a vehicle according to an embodiment of the present invention are described.

[0047] like Figure 1 and Figure 2 As shown, the engine 100 according to the first embodiment of the present application includes: a body 10 and an intercooler assembly 20.

[0048] Among them, a mounting bracket 11 and a throttle flange 12 are arranged on the main body 10, and the intercooler assembly 20 is arranged on the top surface of the main body 10. The intercooler assembly 20 includes: a core 21 and an intake shell 22 and an exhaust shell 23 located at both ends of the core 21. The intake shell 22 is connected to the mounting bracket 11, and the exhaust shell 23 is connected to the throttle flange 12.

[0049] It should be pointed out that a low-pressure EGR system is also integrated on the main body 10. The high-temperature air (mixed with unburned exhaust gas) compressed by the low-pressure EGR system can enter the core 21 through the intake shell 22. After completing the heat exchange in the core 21, the low-temperature and high-pressure gas can enter the throttle valve through the exhaust shell 23, and finally participate in the combustion work in the multiple combustion chambers of the main body 10, thereby achieving the effect of energy saving and emission reduction.

[0050] Specifically, the present application further sets a mounting bracket 11 on the main body 10, and integrates a mounting structure on the throttle flange 12, and then fixes the intake shell 22 to the mounting bracket 11, and fixes the exhaust shell 23 to the throttle flange 12, so as to realize the assembly of the intercooler assembly 20 on the main body 10.

[0051] It is understandable that the mounting structure is integrated on the throttle valve, the throttle valve flange 12 is located on the top surface area of ​​the body 10 , and the corresponding mounting bracket 11 is arranged on the body 10 to fix the intercooler assembly 20 on the top surface of the body 10 .

[0052] According to the engine 100 of the embodiment of the present application, under the premise of meeting the requirements of energy conservation and emission reduction, improving the thermal efficiency of the engine 100, and optimizing the power output, the intercooler assembly 20 is arranged on the top surface of the main body 10 through the mounting structure integrated on the mounting bracket 11 and the throttle flange 12. On the one hand, the arrangement position of the intercooler assembly 20 is more reasonable, which can improve the cooling stability and reliability of the intercooler assembly 20, reduce the probability of engine 100 stalling, and improve the working stability of the engine 100. On the other hand, the installation structure of the intercooler assembly 20 can be simplified, the installation components can be reduced, the installation convenience of the intercooler assembly 20 can be improved, and the difficulty of disassembly and assembly of the intercooler assembly 20 can be reduced, thereby reducing the maintenance cost.

[0053] See also Figure 3 As shown, according to some embodiments of the present application, the mounting bracket 11 and the throttle flange 12 are located on the same side of the body 10 .

[0054] Specifically, the mounting bracket 11 can be constructed as a ram's horn structure, one end of the mounting bracket 11 is connected to the main body 10 (i.e., the engine 100 shell), and can be formed as an integral body or separately arranged, and the mounting bracket 11 and the throttle flange 12 are located on the same side of the main body 10, so that during the assembly process of the intercooler assembly 20, the assembler can assemble it on the same side of the engine 100, that is, assemble the mounting bracket 11 and the intake shell 22 at one end of one side of the engine 100, and assemble the throttle flange 12 and the exhaust shell 23 at the other end of the side, which can further simplify the assembly steps and improve the convenience of disassembly and assembly.

[0055] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the air intake port of the air intake housing 22 is higher than the exhaust port of the exhaust housing 23 , and the exhaust port of the exhaust housing 23 is located at the lowest point of the intercooler assembly 20 .

[0056] Specifically, an intercooler pipe is arranged in the core 21. The internal structure of the intercooler pipe is a no-drop design, and one end is connected to the air intake shell 22, and the other end is connected to the exhaust shell 23, so that the exhaust shell 23 is located at the lowest point, so that the high-pressure gas can be under the action of gravity at the same time, to improve the smoothness of gas flow. In the process of high-temperature and high-pressure gas cooling through the core 21, the condensed water generated in the core 21 can be gathered to the exhaust shell 23 under the action of gravity, and discharged from the exhaust shell 23 located at the lowest point of the intercooler assembly 20, which can improve the problem of condensed water accumulation on the air side of the intercooler assembly 20, reduce the accumulation of condensed water on the air side inside the core 21, and improve the working stability and reliability of the intercooler assembly 20.

[0057] See also Figure 3 As shown, further, a plurality of first mounting points 121 are arranged at equal angle intervals on the throttle flange 12 , and the exhaust housing 23 is mounted on the first mounting points 121 .

[0058] Specifically, the throttle flange 12 is connected to the exhaust shell 23, and a plurality of first mounting positions are arranged on the exhaust shell 23, and a plurality of first mounting points 121 are arranged on the corresponding throttle flange 12. The first mounting points 121 and the first mounting positions are assembled by fasteners, which can improve the connection stability and reliability between the exhaust shell 23 and the throttle flange 12, so as to improve the fixing stability and reliability of the intercooler assembly 20.

[0059] The throttle flange 12 is generally disc-shaped, and a plurality of first mounting points 121 are arranged at equal angles around the throttle flange 12, so that the force distribution is more uniform, and the assembly reliability and stability can also be improved.

[0060] It should be pointed out that the first mounting position can be constructed as a mounting hole, and an assembly bolt can be integrated on the first mounting point 121. After the assembly bolt passes through the mounting hole, it is tightened by an assembly nut to achieve stable fixation of the exhaust housing 23 and the throttle flange 12. Gaskets, bushings and other structures can be arranged between the first mounting position and the first mounting point 121 to reduce the transmission of vibrations generated during the operation of the main body 10 to the intercooler assembly 20, reduce the probability of resonance and clapping between the intercooler assembly and the main body 10, reduce abnormal working noises of the intercooler assembly 20, and avoid loosening of the fastening nuts under the action of vibration, thereby further improving the connection stability and reliability between the exhaust housing 23 and the throttle flange 12.

[0061] Combination Figure 2 and Figure 3 As shown, further, one end of the mounting bracket 11 is connected to the body 10 , and a plurality of second mounting points 111 are provided on the other end of the mounting bracket 11 , and the air inlet shell 22 is mounted on the second mounting points 111 .

[0062] It should be pointed out that the projection of the mounting bracket 11 in the height direction can be a triangle, one corner position of the triangle is connected to the main body 10, and the other two corner positions form a second mounting point 111. Two second mounting positions can be formed on the lower surface of the air intake shell 22, and an assembly bolt is integrated on one of the second mounting positions or the second mounting points 111, and a mounting hole is formed on the other of the second mounting positions or the second mounting points 111. The assembly bolts pass through the mounting holes and are tightened by assembly nuts to improve the connection stability and reliability between the air intake shell 22 and the mounting bracket 11.

[0063] The two second mounting points 111 correspond to the two ends of the air intake shell 22 in the length direction, and achieve corresponding fastening, which can further improve the fixing stability.

[0064] It should be pointed out that a gasket, a bushing and other structures may be arranged between the second mounting position and the second mounting point 111 to reduce the transmission of vibration generated during the operation of the main body 10 to the intercooler assembly 20, reduce the probability of resonance and vibration between the intercooler assembly and the main body 10, reduce abnormal working noise of the intercooler assembly 20, and avoid loosening of the fastening nut under the action of vibration, thereby further improving the connection stability and reliability between the air intake shell 22 and the mounting bracket 11.

[0065] like Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of the present application, the air intake shell 22 defines an air intake chamber, and the extension direction of the air intake chamber is consistent with the arrangement direction of the intercooler pipes in the core 21.

[0066] Specifically, the extension direction of the air intake chamber is consistent with the arrangement direction of the intercooler pipes, so that the air intake chamber can be formed into a transverse straight pipe structure, the air side flow field is more uniform, and the heat exchange efficiency of the intercooler assembly 20 can be further improved.

[0067] It should be pointed out that when the high-temperature gas flow enters the air intake chamber, the flow cross-section will suddenly expand. Due to the inertia of the fluid, it cannot suddenly expand to the entire cross-section according to the shape of the pipe, but there is a gradual expansion process, which generates a large amount of vortex reflux inside the air intake chamber, forming a low-pressure vortex area. Therefore, the pressure of the intercooler pipe facing the air inlet is relatively high, and the gas flow entering is also the largest. From the middle to the edge of the vortex area, the pressure is relatively low and the gas flow is relatively small. Therefore, the speed of the intercooler pipe in the center area is relatively high, and gradually decreases toward the periphery.

[0068] The main reason is: after the intake airflow enters the intake chamber, the fluid directly flushes to the central part of the intercooler tube facing the inlet pipe, and part of the fluid enters the intercooler tube for heat exchange: the other part of the fluid is blocked by the internal structure of the air chamber and the intercooler tube, and the kinetic energy of the fluid is converted into pressure energy to form a high-pressure area, and the fluid diffuses to the surrounding low-pressure area. Therefore, in the surrounding low-pressure area, there is no direct flushing of the inlet section, so the fluid flow entering the intercooler tube is much less than that of the intercooler tube in the middle area, resulting in uneven airflow distribution in the intercooler tube. In the arrangement direction of the intercooler tube, the velocity distribution from top to bottom is uneven, which leads to reduced heat dissipation efficiency of the intercooler assembly 20 and excessive local temperature.

[0069] Based on this, in the air intake shell 22 of the present application, the cross-sectional size of the air intake chamber gradually increases in the direction toward the air intake port.

[0070] When the high-temperature gas flow enters the air intake chamber, the fluid is blocked by the internal structure of the air chamber and the intercooler pipe, and the kinetic energy of the fluid is converted into pressure energy to form a high-pressure area, and the fluid diffuses to the surrounding low-pressure area. Since the exhaust shell 23 is on the other side, the air intake chamber with a flared structure increases the back pressure of the intercooler pipe near the inlet of the air intake shell 22, and the back pressure of the intercooler pipe near the outlet of the exhaust shell 23 is relatively small, so that the flow rate of the intercooler pipe near the inlet of the air intake shell 22 is relatively reduced, the flow rate of the intercooler pipe in the middle area remains stable, and the flow rate of the intercooler pipe near the outlet of the exhaust shell 23 is relatively increased, so as to achieve uniform distribution of the air flow in the intercooler pipe. Such a design makes the flow of the air flow through any intercooler pipe basically the same, and the pressure difference formed by the inlet and outlet of the intercooler pipe remains unchanged, and the size and shape of the intercooler pipe are the same, resulting in the unchanged medium flow in each intercooler pipe. Such a design can maximize the uniformity of airflow distribution of the intercooler assembly 20 , improve the overall heat dissipation effect and heat dissipation efficiency of the intercooler assembly 20 , avoid local overheating, and effectively improve the thermal fatigue strength of the intercooler assembly 20 .

[0071] like Figure 4 As shown, according to some embodiments of the present application, a pressure relief valve and a temperature sensor are also included. The pressure relief valve seat 231 of the pressure relief valve is integrated with the exhaust shell 23 , and the sensor mounting seat 232 of the temperature sensor is also integrated with the exhaust shell 23 .

[0072] In this way, by arranging both the temperature sensor and the pressure relief valve on the exhaust shell 23, and both the temperature sensor and the pressure relief valve are arranged adjacent to the exhaust side of the intercooler assembly 20, the outlet temperature and outlet pressure of the intercooler assembly 20 can be detected more accurately, thereby improving the accuracy and reliability of the outlet temperature and outlet pressure detection, thereby further improving the working stability and reliability of the intercooler assembly 20.

[0073] The vehicle according to the second embodiment of the present application includes: the engine 100 of any one of the above embodiments, and the technical effects thereof are consistent with those of the above engine 100, which will not be described in detail here.

[0074] Other structures and operations of the intercooler assembly 20 and the engine 100 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail herein.
