[0046] The vehicle 100 provided in this embodiment can be a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, or a gasoline-powered vehicle. The vehicle can also be a sedan, truck, bus, lorry, trailer, etc.
[0047] See Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 100 provided in this embodiment. The vehicle 100 includes a body 10 and wheels 20. The body 10 can be used to carry passengers and install components required for the vehicle 100, such as a power system, air conditioning system, and monitoring system. The power system can be a gasoline power system or a hybrid power system, used to provide power for the vehicle 100 to move. The air conditioning system can be used to regulate the interior temperature to improve the comfort of the occupants. The monitoring system can be used to obtain the real-time status of the vehicle 100 to improve the safety of the vehicle 100. The wheels 20 are located below the body 10, used to support the body 10, and can roll to move the body 10.
[0048] In some examples, the vehicle body 10 includes a front engine compartment, a passenger compartment, and a rear compartment arranged in sequence. The front engine compartment is located at the front of the vehicle body 10 and refers to the space below the front hood 6 of the vehicle body 10, which can be used to house components such as the engine; the passenger compartment refers to the area where the driver and passengers sit, and is used by users to ride in the vehicle 100; the rear compartment is located at the rear of the vehicle 100 and usually refers to the space under the trunk of the vehicle 100.
[0049] In some examples, wheel 20 is used to connect to the power system, which drives wheel 20 to rotate, thereby enabling vehicle 100 to travel on the road.
[0050] In some examples, the powertrain of vehicle 100 includes an engine assembly. This engine assembly can be a gasoline engine assembly, a diesel engine assembly, a natural gas engine assembly, a hybrid engine assembly, etc.
[0051] In some implementations, see Figure 2 , Figure 2 for Figure 1 A schematic diagram of the layout of the engine assembly on vehicle 100. This engine assembly includes the engine block 1 and an exhaust gas treatment device. It should be noted that... Figure 2 In this text, L represents the length of the vehicle body, W represents the width of the vehicle body, and HK represents the position of the front of the vehicle.
[0052] In some examples, the engine block 1 can be the block of a gasoline engine, the block of a diesel engine, or the block of a hybrid engine, etc.
[0053] In some examples, the engine block 1 includes an exhaust port 11. The exhaust port 11 is used to discharge gases produced by the combustion of fuel such as oil within the engine.
[0054] To further treat the gases produced by fuel combustion in the engine, such as filtering out carbon monoxide, hydrocarbons, and nitrogen oxides, an exhaust gas treatment device is connected to the exhaust port 11 and is used to treat the exhaust gases produced by the engine block 1. The exhaust gas treatment device is located on the side of the engine block 1 facing the front of the vehicle.
[0055] In some examples, the exhaust gas treatment device is directly connected to the exhaust port 11.
[0056] In other examples, the exhaust gas treatment device is indirectly connected to the exhaust port 11, for example, a turbocharger 2 is provided between the exhaust gas treatment device and the exhaust port 11 of the engine block.
[0057] In some examples, the exhaust treatment device may include a separate but connected catalytic converter and a muffler. The catalytic converter treats carbon monoxide, hydrocarbons, and nitrogen oxides produced by fuel combustion in the engine. The muffler reduces the noise generated by engine exhaust.
[0058] In other examples, the exhaust treatment device may include an integrated catalytic converter and a muffler.
[0059] In the above scheme, the exhaust gas treatment device is set on the side of the engine block 1 facing the front of the vehicle. Compared with the arrangement of setting the exhaust gas treatment device on the side of the engine block 1 near the rear of the vehicle, the structure is more compact, makes full use of the space at the front of the vehicle, and saves the space of the engine block 1 near the rear of the vehicle, thereby improving the utilization rate of the space of the vehicle 100.
[0060] In some embodiments, the engine assembly also includes an exhaust manifold, with its inlet connected to the exhaust port 11 and its outlet connected to the inlet of the exhaust gas treatment device. Since the engine body generally includes multiple combustion chambers for fuel combustion, the exhaust manifold is used to collect and discharge the gases produced by fuel combustion in multiple combustion chambers, facilitating centralized treatment of these gases by the exhaust gas treatment device.
[0061] In some examples, the exhaust manifold may include multiple branch pipes and a main pipe. Each branch pipe connects to a combustion chamber of an engine and the inlet of the main pipe, thus collecting the gases produced by combustion in the multiple combustion chambers of the engine into the main pipe through the branch pipes. The outlet of the main pipe is connected to the inlet of an exhaust gas treatment device, through which the gases produced by combustion in the multiple combustion chambers of the engine are delivered to the exhaust gas treatment device.
[0062] In other examples, the exhaust manifold may be a series of branches, each connected to the inlet of an engine combustion chamber and an exhaust aftertreatment device.
[0063] In some other examples, the exhaust manifold inlet is integrated with the engine block exhaust port 11. In this case, the exhaust manifold is integrated with the engine cylinder head, and the engine block exhaust port 11 can be considered as the exhaust port on the cylinder head.
[0064] In some embodiments, the engine assembly further includes a turbocharger 2, the inlet of which is connected to the outlet of the exhaust manifold, and the outlet of the turbocharger 2 is connected to the inlet of the exhaust gas treatment device. Exhaust gas discharged through the exhaust manifold drives the turbocharger 2 to pressurize the air flowing through it, increasing the engine's intake air density and improving power output.
[0065] In some examples, the turbocharger 2 has a first inlet and a second inlet 23. The first inlet is used to connect to the outlet of the exhaust manifold, and the second inlet 23 is used to supply air into the turbocharger. The side of the second inlet 23 away from the turbocharger 2 can be connected to an air filter and an intake manifold, etc.
[0066] In some examples, booster 2 can be turbocharger 2.
[0067] In other examples, the supercharger 2 can be a mechanical supercharger 2 or an electric supercharger 2.
[0068] In some embodiments, the exhaust gas treatment device further includes a degassing module 3 for treating exhaust gas. The inlet of the degassing module 3 is connected to the outlet of the booster 2, and the outlet of the degassing module 3 is used to discharge exhaust gas. The exhaust gas, pressurized by the booster 2, enters the degassing module 3 and can be treated by the degassing module 3 to reduce the pollution of the exhaust gas.
[0069] In some examples, the exhaust noise reduction module 3 can be equipped with an expansion chamber and a resonance cavity, etc., to absorb and reduce exhaust noise using acoustic principles.
[0070] In some specific examples, the muffler module 3 includes an integrated catalytic converter and muffler. In this case, the catalytic converter inlet is connected to the turbocharger 2 outlet, the catalytic converter outlet is connected to the muffler inlet, and the muffler outlet is used to exhaust exhaust gases. Integrating the catalytic converter and muffler results in a compact structure, occupies less space, and improves the space utilization of the vehicle 100. Furthermore, because the muffler in the muffler module 3 has noise reduction functions, the vehicle 100 has superior NVH performance.
[0071] In some examples, the catalyst and the muffler each have separate housings, and the muffler module 3 includes a total housing that integrates the catalyst and the muffler through their separate housings inside the total housing of the muffler module 3.
[0072] In other examples, the muffler module 3 includes a housing with an internal mounting cavity for mounting the catalyst and muffler components. In this case, the catalyst and muffler share a single housing instead of having separate housings, thereby improving the integration of the muffler and reducing the space it occupies.
[0073] In some embodiments, the muffler module 3 is located on the side of the engine block 1 facing the front of the vehicle, and the turbocharger 2 is located between the engine block 1 and the muffler module 3. Positioning the muffler module 3 on the side of the engine block 1 facing the front of the vehicle, compared to the conventional solution where the muffler and catalytic converter are located on the side of the engine block closer to the rear of the vehicle, fully utilizes the front compartment space of the vehicle 100 and improves the utilization rate of the front compartment space.
[0074] In other embodiments, the engine block 1 and the anti-bulk module 3 are arranged along the length of the vehicle body 10, and the turbocharger 2 is located on the side of the engine block 1 or on the side of the anti-bulk module 3.
[0075] In some embodiments, the exhaust gas treatment device further includes an exhaust tailpipe 4, the inlet of which is connected to the outlet of the muffler module 3, and the outlet of which is connected to the outside. This allows the vehicle 100 to adopt a front-to-rear seating arrangement, with the exhaust side positioned on the windward side of the vehicle 100 during travel, facilitating heat dissipation from the exhaust system and reducing the impact of heat damage on the front of the vehicle 100 and the cab. Furthermore, since the catalytic converter and muffler are integrated within the muffler module 3, the muffler module 3 has a noise reduction function, mitigating engine exhaust noise to some extent.
[0076] In some examples, the exhaust tailpipe 4 and the exhaust module 3 are arranged along the width direction of the vehicle 100. The axial direction of the exhaust tailpipe 4 may be aligned with the width direction of the vehicle 100.
[0077] In other examples, the exhaust tailpipe 4 is arranged axially along the length of the vehicle 100.
[0078] In some embodiments, the exhaust tailpipe 4 is located on one side of the exhaust module 3 in the width direction of the vehicle 100. By placing the exhaust tailpipe 4 on one side of the exhaust module 3 in the width direction of the vehicle 100, the original exhaust manifold spanning the length direction of the vehicle 100 is eliminated, optimizing the space layout of the chassis and providing more available space for battery placement in hybrid vehicles.
[0079] In some examples, the exhaust tailpipe 4 is located to the left of the exhaust module 3.
[0080] In other examples, the exhaust tailpipe 4 is located to the right of the de-packing module 3.
[0081] In some implementations, see Figure 2The turbocharger 2 has two outlets: a first outlet 21 and a second outlet 22. The first outlet 21 is connected to the inlet of the exhaust module 3. The engine assembly also includes an intake device connected to the air intake of the engine block 1, and the second outlet 22 is connected to the intake device. The turbocharger 2 connects to the air intake of the exhaust module 3 via the first outlet 21, ensuring smooth exhaust gas discharge and thus guaranteeing normal engine operation and performance optimization. The turbocharger 2 connects to the intake device of the engine block 1 via the second outlet 22, increasing the engine's intake volume, thereby improving engine power and torque, making the car more powerful. By providing two outlets, the turbocharger 2 improves exhaust efficiency and avoids excessive back pressure, which could affect engine power and torque.
[0082] In some examples, the intake system mainly includes an air filter, intake manifold, throttle body, and intake manifold. The air filter filters dust and other impurities from the air; the throttle body controls the amount of air entering the engine; and the intake manifold delivers air to the various combustion chambers of the engine. These components work together to ensure that the engine continuously receives clean, dry, and stable air, thereby ensuring the normal operation of the engine.
[0083] In some embodiments, the engine block 1 includes a cylinder block and a cylinder head. The cylinder block has a cylinder bore 12 for piston movement. The cylinder head is connected to the cylinder block and covers the cylinder bore 12. An exhaust port 11 is located at the front end of the cylinder head. Since the anti-fouling module 3 is located on the side of the engine block 1 near the front of the vehicle, placing the exhaust port 11 of the engine block 1 at the front end of the cylinder head facilitates the connection between the exhaust port 11 and the anti-fouling module 3.
[0084] At this time, the vehicle 100 adopts a front-row, rear-entry layout, with the exhaust side located on the windward side of the vehicle 100 during travel. This facilitates heat dissipation from the exhaust system and reduces the impact of heat damage on the front of the vehicle 100 and the cab.
[0085] In other examples, the exhaust port 11 is located at the rear end of the cylinder head.
[0086] In some real-time methods, see Figure 3 , Figure 3 for Figure 2 A schematic diagram of the engine assembly layout on vehicle 100 from another perspective. It should be noted that... Figure 3 In the diagram, L represents the length of the vehicle body 10, H represents the height of the vehicle body 10, and HK represents the front end. The cylinder bore axis 121 is aligned with the height of the vehicle 100, or it may be inclined to the height of the vehicle 100. The cylinder bore axis 121 can be aligned with the height of the vehicle 100 or at a certain angle, offering flexible arrangement options and facilitating better utilization of the space in the front engine compartment of the vehicle 100.
[0087] In some examples, the axis 121 of the cylinder bore is aligned with the height direction of the vehicle 100, that is, the angle between the axial direction of the cylinder bore 12 and the height direction of the vehicle 100 is 0°.
[0088] In other examples, the axis 121 of the cylinder bore is set at an angle to the height direction of the vehicle 100.
[0089] In some examples, along the height direction of the vehicle 100, the tilt direction of the cylinder bore 12 can be away from the front of the vehicle or close to the front of the vehicle.
[0090] In some embodiments, the angle between the cylinder bore axis 121 and the height direction of the vehicle 100 is greater than or equal to 0° and less than or equal to 20°. The large range of cylinder bore 12 tilt angles improves the utilization of the front engine compartment space of the vehicle 100. When the angle between the cylinder bore 12 axis and the height direction of the vehicle 100 is greater than 20°, there is a risk of oil churning in the engine. When the angle between the cylinder bore axis 121 and the height direction of the vehicle 100 is less than or equal to 20°, the engine block 1 can be tilted relative to the height direction of the vehicle 100 to improve the utilization of the front engine compartment space while ensuring engine performance.
[0091] In some examples, the angle f between the axis 121 of the cylinder bore and the height direction of the vehicle 100 can be 0°, 5°, 10°, 15°, 20°, etc.
[0092] In some real-time configurations, there are multiple cylinder bores 12, which are arranged along the width of the vehicle 100. By arranging multiple cylinder bores 12 along the width of the vehicle 100, the utilization rate of the front engine compartment space of the vehicle 100 is improved.
[0093] In other examples, the multiple cylinder bores 12 of the engine block 1 are arranged along the length of the vehicle 100.
[0094] In some implementations, see Figure 3 The engine block 1 also includes an oil pan 5, which is connected to the lower side of the cylinder block. By providing the oil pan 5 below the cylinder block, a certain amount of lubricating oil can be stored in the oil pan 5 to ensure that the engine has sufficient lubricating oil supply during operation.
[0095] In some examples, the oil pan 5 is a dry oil pan 5.
[0096] In other examples, the oil pan 5 is a wet oil pan 5.
[0097] In some embodiments, the lower surface 51 of the oil pan is parallel to the length direction of the vehicle 100, which can reduce airflow resistance when the vehicle 100 is in motion and reduce energy consumption.
[0098] In some embodiments, the powertrain of vehicle 100 also includes a transmission 7, which is connected to the engine block 1. By adjusting the transmission ratio of the transmission 7, the engine can maintain efficient operation under different road conditions.
[0099] In some examples, the transmission 7 can be a manual transmission 7, a hydraulic automatic transmission 7, a continuously variable transmission 7, a dual-clutch transmission 7, a hybrid transmission 7, etc.
[0100] In some implementations, see Figure 2 The transmission 7 is located on one side of the engine block 1 in the width direction of the vehicle 100. At this time, the line connecting the transmission 7 and the engine block 1 is the same as or approximately the same as the width direction of the vehicle 100, and the engine is arranged transversely, which improves the space utilization of the front engine compartment of the vehicle 100.
[0101] In some examples, along the length of the vehicle body 10, the transmission 7 can be located on the left side of the engine block 1 or on the right side of the engine block 1.
[0102] In some embodiments, the vehicle 100 also includes a body 10, which has a front engine compartment where the engine assembly is located. Positioning the engine assembly in the front engine compartment improves the utilization of the space in the front engine compartment of the vehicle 100.
[0103] In other examples, the engine assembly is located under the passenger compartment or in the rear compartment of the vehicle body 10.
[0104] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0105] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
