[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0063] Reference Figure 1 and 2 As shown in the figure, the vehicle 1 of this application includes: a passenger compartment 10 and an engine compartment 20.
[0064] The passenger compartment 10 is used to accommodate the passengers of vehicle 1; the engine compartment 20 is used to accommodate the engine 100 of vehicle 1. Of course, the engine compartment 20 can also accommodate other devices of vehicle 1, such as motors, air conditioners, etc.
[0065] As a specific plan, refer to Figure 1 and Figure 2 As shown, the vehicle 1 of this application adopts a front-mounted engine compartment 20.
[0066] For ease of explanation, Figure 1 and Figure 2 In the specific implementation shown, the directions are indicated by "up, down, left, right, front, and back". It can be understood that the subsequent descriptions based on the directions of "up, down, left, right, front, and back" are only to illustrate the relative directions and positional relationships, rather than the absolute directions and positional relationships.
[0067] Furthermore, the orientations of "up, down, left, right, front, and back" in this application are based on the condition that vehicle 1 is traveling on a level road. When vehicle 1 is traveling on an inclined road, the direction and position determined by the orientations of "up, down, left, right, front, and back" in this application will also change. Therefore, the orientations of "up, down, left, right, front, and back" used in the following description should not be construed as an absolute limitation on the directional and positional relationships of this application.
[0068] Reference Figure 2 As shown, the exhaust side (SIDE B) of the engine 100 body 101 is positioned away from the passenger compartment 10, meaning that in the direction of normal vehicle travel, the engine compartment 20 is located in front of the passenger compartment 10. This reduces safety risks to the passenger compartment 10 and facilitates thermal management of the passenger compartment 10.
[0069] Reference Figures 3 to 8 As shown, the engine 100 of this application includes: a main body 101, a turbocharger 102, an intercooler 103, an intake manifold 104, a throttle valve 105, an EGR device 106, an EGR controller, a muffler 108, an intake pipe 109, and an air purifier 110.
[0070] The engine block 101 serves as the main body of the engine, used to output power and support other components. Generally, the engine block 101 includes a cylinder block 1011 and a cylinder head 1012. The engine block 101 has a combustion chamber inside for fuel to mix with air and burn, thereby converting the chemical energy of fuel combustion into mechanical energy.
[0071] Generally speaking, the side of the body 101 used for intake is defined as intake side A, the side of the body 101 used for exhaust is defined as exhaust side B, the side of the body 101 close to the cylinder block 1011 is defined as cylinder block side D, and the side of the body 101 close to the cylinder head 1012 is defined as cylinder head side C.
[0072] Reference Figures 3 to 8 As shown, as an example, the first direction D1, the second direction D2, and the third direction D3 of the engine body 100 in this application are defined based on the rotation axis 101a of the crankshaft of the engine body 101; wherein, the first direction D1 and the second direction D2 are both perpendicular to the rotation axis 101a; and the first direction D1 and the second direction D2 are perpendicular to each other, the specific relationship of which can be found in the reference. Figures 5 to 7 As shown.
[0073] Of course, other methods can be used to define the second direction D2, the first direction D1, and the third direction D3 in this application. The second direction D2, the first direction D1, and the third direction D3 are only used to define the relative positional relationship. They only need to represent different directions. In some embodiments of this application, the second direction D2, the first direction D1, and the third direction D3 are three mutually perpendicular directions.
[0074] As a specific scheme, the first direction D1 is the direction from exhaust side B to intake side B, the second direction D2 is the extension direction parallel to the cylinder bore axis of the engine (not shown in the figure), and the third direction is the extension direction parallel to the rotation axis 101a of the crankshaft of the engine 100.
[0075] It should be noted that, in this application, "in the first direction D1" refers to the positional relationship between the corresponding components when observed along the first direction D1; similarly, "in the second direction D2" refers to the positional relationship between the corresponding components when observed along the second direction D2; and "in the third direction D3" refers to the positional relationship between the corresponding components when observed along the third direction D3.
[0076] For example, "the turbocharger 102 and the intake manifold 104 at least partially overlap in the first direction D1 of the body 101" means that when observed along the first direction D1, there is an overlapping portion between the turbocharger 102 and the intake manifold 104.
[0077] Reference Figures 3 to 8 As shown, the turbocharger 102 is used to increase the intake pressure of the main body 101. The function of the turbocharger 102 is to increase the gas pressure, which can increase the intake pressure to assist combustion and improve the combustion efficiency of the engine.
[0078] Intercooler 103 is used to reduce the intake air temperature entering the combustion chamber of main body 101; generally, intercooler 103 is used to cool the gas temperature flowing from turbocharger 102 to intake manifold 104. Due to the boosting function of turbocharger 102, the gas passing through turbocharger 102 tends to have an increased temperature.
[0079] The intake pipe 109 is connected between the turbocharger 102 and the intercooler 103. The intake pipe 109 can guide the gas pressurized by the turbocharger 102 into the intercooler 103.
[0080] The intake manifold 104 is used to distribute the intake air of the main body 101. The intake manifold 104 can distribute the gas output from the intercooler 103 to different combustion chambers of the main body 101.
[0081] Throttle valve 105 is directly connected between intercooler 103 and intake manifold 104. Throttle valve 105 can be used to adjust the intake air volume, thereby controlling the combustion of fuel and thus controlling the power output of the main body 101.
[0082] In related technologies, the throttle valve 105 is connected to the intercooler 103 and the intake manifold 104 via pipes, which often results in pressure loss due to the flow resistance of the pipes.
[0083] Therefore, in this application, in order to avoid pressure loss and improve the integration of the engine 100, the intercooler 103 is directly connected to the intake manifold 104 through the throttle valve 105. That is, the intake port of the throttle valve 105 (not shown in the figure) is directly connected to the intercooler 103; the outlet port of the throttle valve 105 (not shown in the figure) is directly connected to the intake manifold 104. No pipelines are provided between the throttle valve 105 and the intercooler 103, or between the throttle valve 105 and the intake manifold 104.
[0084] The EGR device 106 is fluidly connected to the turbocharger 102. The main function of the EGR device 106 is to introduce some of the exhaust gas from the main body 101 into the intake system, and then into the combustion chamber of the main body 101 to participate in combustion. The CO2, water vapor and other gases in the exhaust gas recovered by the EGR device 106 have high specific heat capacity, which can effectively absorb the heat of combustion, thereby reducing the peak temperature in the cylinder and suppressing NOx formation.
[0085] As a specific embodiment, the pipeline for the EGR device 106 to participate in secondary combustion is the outlet pipe 106a of the EGR device 106.
[0086] EGR controller 107 is electrically connected to EGR device 106. EGR controller 107 can be used to control EGR device 106. The exhaust gas recovery ratio of EGR device 106 needs to be dynamically adapted and controlled according to the operating conditions of main body 101. Therefore, EGR controller 107 can effectively maximize the efficiency of EGR device 106 and ensure the normal operation of main body 101.
[0087] Purifier 110 is used to purify the exhaust gas emitted by engine 100. Purifier 110 can convert harmful substances in the exhaust gas into harmless substances through a chemical reaction. Muffler 108 is fluidly connected to purifier 110 to reduce exhaust noise. Muffler 108 can serve as the final end of the exhaust system, meaning that the exhaust gas can be discharged into the environment after being treated by muffler 108. Therefore, as a specific solution, in this application, muffler 108 is provided with exhaust pipe 108a as the final exhaust pipe of the exhaust system.
[0088] As an alternative, in addition to handling a separate air purifier 110, the muffler 108 can also integrate another air purifier 110; or, the external air purifier 110 can be eliminated, and the air purifier 110 can be directly integrated into the muffler 108.
[0089] The above describes the various parts of the engine 100 of this application. The specific structures of the turbocharger 102, intercooler 103, intake manifold 104, throttle valve 105, EGR device 106, EGR controller 107, muffler 108, and purifier 110 are not the focus of this application's improvement and are technical solutions known to those skilled in the art, so they will not be described in detail here.
[0090] Reference Figures 3 to 7 As shown, with the main body 101 as a reference, the positional relationship of the turbocharger 102, intercooler 103, intake manifold 104, throttle body 105, EGR device 106, EGR controller 107, muffler 108, intake pipe 109 and air purifier 110 in the engine 100 of this application is explained as follows.
[0091] Reference Figures 3 to 7 As shown, the turbocharger 102 is located on the exhaust side B of the main body 101; the intake manifold 104 is located on the intake side A of the main body 101; a portion of the intercooler 103 is located on the intake side A of the main body 101, and the other portion is located on the cylinder head side C of the main body 101; both the turbocharger 102 and the intake manifold 104 are located close to the cylinder head side C of the main body 101; the intercooler 103 is in fluid communication between the intake manifold 104 and the turbocharger 102.
[0092] This approach effectively reduces the complexity of the piping layout between the turbocharger 102 and the intercooler 103, thereby reducing the length of the piping and lowering pressure loss.
[0093] For example, by placing both the turbocharger and intercooler close to the cylinder head, it is easier to connect them through a shorter intake pipe, thus avoiding pressure loss; at the same time, the intercooler and intake manifold are both located on the intake side, which provides a basis for simplifying the piping from the position.
[0094] Furthermore, the turbocharger 102, intercooler 103, intake manifold 104, and throttle body 105 are relatively concentrated and close to the cylinder head side, which improves the integration of the intake and exhaust system.
[0095] As a specific solution, the main body 101 includes a cylinder head cover (not shown in the figure), and the intercooler 103 can be fixed on the intake manifold 104 and the cylinder head cover, thereby further reducing the space required for installing the intercooler 103 and improving the convenience and stability of the installation of the intercooler 103.
[0096] As a specific solution, the turbocharger 102 can be fixed to the cylinder head and directly connected to the purifier 110, which simplifies the installation of the turbocharger 102.
[0097] In some embodiments, the turbocharger 102, intercooler 103, and intake manifold 104 are directly fixed to the main body 101, which also helps to improve the engine's NVH performance.
[0098] Reference Figures 3 to 7As shown, in some embodiments of this application, the body 101 is at least partially disposed between the turbocharger 102 and the intake manifold 104; in the first direction D1 of the body 101, the turbocharger 102 and the intake manifold 104 at least partially overlap; in the first direction D1 of the body 101, the turbocharger 102 and the intercooler 103 at least partially overlap; in the first direction D1, the intake manifold 104 and the intercooler 103 at least partially overlap.
[0099] In this way, space can be effectively saved through the spatial arrangement of the turbocharger 102, intercooler 103 and intake manifold 104.
[0100] Reference Figures 3 to 7 As shown, in some embodiments of this application, the intake pipe 109 is disposed on the cylinder head side SIDE C of the body 101.
[0101] Reference Figures 3 to 7 As shown, in some embodiments of this application, in the second direction D2, the intake pipe 109 and the body 101 at least partially overlap.
[0102] Reference Figures 3 to 7 As shown, in some embodiments of this application, in the second direction D2, the intake pipe 109 and the intake manifold 104 at least partially overlap.
[0103] Reference Figures 3 to 7 As shown, in some embodiments of this application, in the second direction D2, the intake pipe 109 and the supercharger 102 at least partially overlap; in the third direction D3 of the body 101, the intake pipe 109 and the intercooler 103 at least partially overlap.
[0104] This not only reduces the length of the intake pipe 109, but also effectively lowers the overall dimensions of the engine 100 in the second direction D2.
[0105] Reference Figures 3 to 7 As shown, in some embodiments of this application, the intercooler 103 is directly connected to the intake manifold 104 via the throttle valve 105.
[0106] Reference Figures 3 to 7 As shown, in some embodiments of this application, the throttle valve 105 and the intake manifold 104 at least partially overlap in the second direction D2.
[0107] Reference Figures 3 to 7 As shown, in some embodiments of this application, the throttle valve 105 and the intercooler 103 at least partially overlap on the third direction D3 of the body 101.
[0108] In this way, the space can be effectively utilized to arrange the throttle body 105, and the throttle body 105 is directly connected to the intercooler 103 and the intake manifold 104, which effectively reduces the pressure loss caused by the previous connection through additional pipelines.
[0109] Reference Figures 3 to 7 As shown, in some embodiments of this application, the EGR controller 107 body 101 is positioned on the exhaust side (SIDE B) and near the cylinder head side (SIDE C) of the body 101.
[0110] Reference Figures 3 to 7 As shown, in some embodiments of this application, on a third-direction D3 of the body 101, the EGR device 106 and the EGR controller 107 at least partially overlap.
[0111] The EGR device 106 is located on the exhaust side (SIDE B) of the main body 101 and on the cylinder head side (SIDE C) of the main body 101; the turbocharger 102 is located between the main body 101 and the EGR device 106. In this way, the EGR device 106 no longer occupies the space below the turbocharger 102, thus facilitating the placement of a larger muffler 108.
[0112] The EGR device 106 is tilted to the third direction D3 relative to the main body 101, which facilitates fluid communication between the purifier and the booster and allows for a shorter pipe connection.
[0113] Furthermore, the EGR device 106 is closer to the cylinder head side than the muffler 108, which provides sufficient space for the muffler 108. At the same time, the extension direction of the EGR device 106 also helps to reduce the overall space occupied by the engine 100.
[0114] Reference Figures 3 to 7 As shown, in some embodiments of this application, the purifier 110 is disposed on the exhaust side SIDE B of the body 101 and on the cylinder head side SIDE C of the body 101; in the first direction D1, the purifier 110 and the turbocharger 102 at least partially overlap.
[0115] In this way, the space on one side of the booster 102 is effectively utilized, while the purifier 110 is easily connected to both the booster 102 and the muffler 108.
[0116] Reference Figures 3 to 7 As shown, in some embodiments of this application, the muffler 108 is disposed on the exhaust side SIDE B of the body 101 and close to the cylinder side SIDE D of the body 101.
[0117] Reference Figures 3 to 7As shown, in some embodiments of this application, the muffler 108 and the booster 102 at least partially overlap in the second direction D2.
[0118] Reference Figures 3 to 7 As shown, in some embodiments of this application, the muffler 108 and the body 101 at least partially overlap in the first direction D1.
[0119] Reference Figures 3 to 7 As shown, in some embodiments of this application, the muffler 108 is at least partially embedded in the third direction D3 of the body 101. Specifically, the side of the muffler 108 near the body 101 is recessed in a direction away from the body 101 to form a receiving space, and the side of the body 101 near the muffler 108 can be partially disposed in the receiving space. As a more specific solution, the side of the muffler 108 near the body 101 can be contoured according to the outline of the body, thereby improving the fit between the two and making the overall size of the engine more compact.
[0120] In this way, sufficient space is provided for the muffler 108 on the exhaust side B of the body 101, avoiding the muffler 108 from extending too far beyond the body 101 and causing the engine 100 to have an irregular shape. At the same time, the muffler 108 is adapted to the shape of this application, further saving space.
[0121] Reference Figures 3 to 7 As shown, in some embodiments of this application, the muffler 108 is provided with an exhaust pipe 108a; the exhaust pipe 108a extends beyond the body 101 in a third direction D3. That is, the muffler 108 performs side exhaust, which can save space in the front-rear direction and also reduce the thermal impact of exhaust on the vehicle structure to a certain extent.
[0122] According to a second aspect of this disclosure, this application also provides a powertrain including the engine 100 described above.
[0123] According to a third aspect of this disclosure, this application also provides a vehicle 1, which includes the aforementioned engine 100 or the aforementioned powertrain, the largest protected subject having all the beneficial effects of the aforementioned second smallest protected subject, which will not be repeated here.
[0124] In some embodiments, the engine 100 can be tilted, meaning that the cylinder bore axis of the engine 100 intersects the longitudinal direction (front-to-back direction) of the vehicle 1 at an angle. This provides more space for the muffler, thereby increasing the noise reduction capacity and ensuring the noise reduction effect.
[0125] The vehicle 1 may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.
