[0032] The first aspect of this application provides an engine system 10 for a vehicle. Figure 1 This is a structural schematic diagram of one embodiment of the engine system 10 of the vehicle provided by the client. Figure 2 yes Figure 1 Top view of the structure shown. Figure 3 yes Figure 2 Rear view from the perspective of the structure shown. Figure 4 yes Figure 2 The left view from the perspective of the structure shown. Figure 5 yes Figure 1 The exploded view of the structure shown.
[0033] Combination Figures 1-5The vehicle's engine system 10 includes a cylinder head 11, a pre-combustion chamber assembly 12, and an ignition coil 13. The cylinder head 11 is located on top of the engine block and, together with the cylinder wall of the engine block, forms the main combustion chamber. The cylinder head 11 performs key functions such as sealing, combustion control, heat dissipation, and support for the valve train system. The pre-combustion chamber assembly 12 forms a pre-combustion chamber, which is typically connected to the main combustion chamber through a narrow channel or nozzle. During the engine's ignition phase, the ignition coil 13 is used to ignite the pre-combustion chamber assembly 12. A small amount of rich air-fuel mixture (gasoline engine) or diesel fuel (diesel engine) can be ignited in the pre-combustion chamber to generate a high-temperature, high-pressure flame. The flame is then injected at high speed into the main combustion chamber through a small nozzle, igniting the lean air-fuel mixture (gasoline engine) or promoting more uniform combustion (diesel engine). The pre-combustion chamber accelerates the combustion speed in the main combustion chamber, achieving more efficient energy release and reducing harmful gas emissions.
[0034] Figure 6 This is a schematic diagram of the upper part of the structure shown in the figure. Figure 7 yes Figure 6 A cross-sectional view of the structure shown.
[0035] Combination Figures 5-7 The pre-combustion chamber assembly 12 is partially embedded within the cylinder head 11, with its height aligned with that of the cylinder head 11. At this point, the top of the pre-combustion chamber assembly 12 protrudes from the top wall of the cylinder head 11, while its bottom communicates with the main combustion chamber of the engine. The height of the pre-combustion chamber assembly 12 can be the height of its main body, and the portion of the pre-combustion chamber assembly 12 protruding from the top of the cylinder head 11 can be a small portion of its structure; that is, most of the structure of the pre-combustion chamber assembly 12 is located within the cylinder head 11. During the manufacturing process of the cylinder head 11, a receiving groove can be formed, allowing the pre-combustion chamber assembly 12 to be positioned within this groove.
[0036] The ignition coil 13 is positioned directly above the pre-combustion chamber assembly 12. In this configuration, the orthographic projection of the ignition coil 13 along the height of the cylinder head 11 coincides with at least a portion of the pre-combustion chamber assembly 12. The specific positional relationship between the ignition coil 13 and the cylinder head 11 can be determined based on the arrangement of other structures. The bottom of the ignition coil 13 connects to the exposed top of the pre-combustion chamber assembly 12 on the cylinder head 11; therefore, the ignition coil 13 is also positioned above the cylinder head 11.
[0037] This arrangement embeds the pre-combustion chamber assembly 12 into the cylinder head 11, achieving integrated design between the pre-combustion chamber assembly 12 and the cylinder head 11, thus achieving a compact structural layout to some extent. Furthermore, placing the ignition coil 13 directly above the pre-combustion chamber assembly 12 facilitates connection between the ignition coil 13 and the pre-combustion chamber assembly 12, further reducing the structural complexity. Additionally, placing the ignition coil 13 directly above the pre-combustion chamber facilitates the arrangement of other components, also contributing to a compact structural layout.
[0038] Continue to combine Figures 5-7 In some specific embodiments, the pre-combustion chamber assembly 12 is located in a predetermined central region in the left-right direction d1 of the cylinder head, so that the distance between the pre-combustion chamber assembly 12 and the upper end of the left-right direction d1 of the cylinder head is greater than a predetermined distance.
[0039] In this design, the left-right direction (d1) of the cylinder head aligns with the left-right direction of the engine, which is perpendicular to its front-rear direction. The rear side of the engine in the front-rear direction is the flywheel side. In some applications, the front end of the engine in the front-rear direction is the accessory drive side, typically equipped with belts, chains, etc., responsible for powering the engine itself. The rear end of the engine in the front-rear direction is the power output side, typically equipped with a flywheel / gearbox, responsible for transmitting power to the vehicle. In some applications, the front-rear direction of the engine generally aligns with the width direction of the vehicle.
[0040] The preset central region is the central region of the cylinder head 11 in the left and right directions, which is set in advance according to certain parameters. It is relatively central in the left and right directions, so that the two ends of the pre-combustion chamber assembly 12 in the left and right directions d1 of the cylinder head are close to the two ends of the cylinder head in the left and right directions d1, and thus the distance between the pre-combustion chamber assembly 12 and the upper end of the cylinder head in the left and right directions d1 is greater than the preset distance.
[0041] It should be understood that by arranging the pre-combustion chamber assembly 12 in a predetermined central region of the cylinder head 11, the ignition coil 13 and related structures on the cylinder head 11 can be located in the central region of the cylinder head 11, thereby facilitating the installation of other structures.
[0042] Combination Figure 6 In some specific embodiments, the vehicle's engine system 10 also includes a first cylinder head cover 141 and a second cylinder head cover 142, the first cylinder head cover 141 and the second cylinder head cover 142 being arranged at intervals in the left-right direction d1 of the cylinder head, and the ignition coil 13 being disposed at the gap between the first cylinder head cover 141 and the second cylinder head cover 142.
[0043] Specifically, the cylinder head cover prevents dust and debris from entering the cylinder head 11, seals the engine oil to prevent leakage, integrates an oil-gas separator to expel exhaust gas, and separates the engine oil for return to the engine. Furthermore, in this embodiment, the first cylinder head cover 141 and the second cylinder head cover 142 can integrate part of the intake pipe 111, thereby achieving a compact structural arrangement. When the first cylinder head cover 141 and the second cylinder head cover 142 are spaced apart in the left-right direction d1 of the cylinder head, the top of the cylinder head 11, the first cylinder head cover 141, and the second cylinder head cover 142 form a recessed area, which is located at the aforementioned gap position. At this time, the ignition coil 13 is positioned at the gap position between the first cylinder head cover 141 and the second cylinder head cover 142 (of course, the ignition coil 13 does not necessarily have to be entirely within the gap; for example, the top of the ignition coil 13 can be located above the gap), facilitating the installation of the ignition coil 13 and related structures, and providing protection for some structures at the gap position.
[0044] Combination Figure 7 In some specific embodiments, the pre-combustion chamber assembly 12 includes an injector 121 and a spark plug 122. The injector 121 and the spark plug 122 are disposed inside the pre-combustion chamber assembly 12. The spark plug 122 is connected to the ignition coil 13 through a connecting wire assembly 123. The ignition coil 13 is used to ignite the pre-combustion chamber assembly 12 through the spark plug 122.
[0045] Specifically, the pre-combustion chamber assembly 12 may be provided with a cavity, in which an injector 121 and a spark plug 122 are disposed. The injector 121 is used to precisely atomize fuel and inject it into the cavity, where it mixes with air to form a combustible mixture, thereby providing a combustion source for the pre-combustion chamber assembly 12. The ignition coil 13 is connected to a battery, which converts the low voltage of the battery into high voltage, generating an electric spark through the spark plug 122 in the pre-combustion chamber to ignite the rich mixture (gasoline engine) or diesel / alternative fuel (diesel engine, hydrogen engine, etc.) in the pre-combustion chamber. The connecting wire assembly 123 may be a high-voltage damping wire to transmit high voltage to the spark plug 122.
[0046] Combination Figure 6 as well as Figure 7 In some specific embodiments, the engine system also includes a fuel rail 15 and a fuel pump 16. The fuel rail 15 is disposed above the cylinder head 11 and its length direction is consistent with the front-rear direction d2 of the cylinder head. The fuel pump 16 is disposed at one end of the fuel rail 15. The fuel rail 15 is connected to the fuel pump 16 and the pre-combustion chamber assembly 12.
[0047] It should be understood that the fuel pump 16 can then guide fuel into the fuel rail 15, which in turn transmits fuel to the pre-combustion chamber assembly 12, specifically to the injector 121. Considering the arrangement of the first cylinder head cover 141 and the second cylinder head cover 142, the fuel rail 15 can be positioned at the gap between them, with the length of the fuel rail 15 aligned with the length of this gap, which in turn aligns with the longitudinal direction d2 of the cylinder head.
[0048] Continue to combine Figures 5-7 In some specific embodiments, there are multiple pre-combustion chamber assemblies 12 and ignition coils 13. The figure shows four pre-combustion chamber assemblies 12 and four ignition coils 13, but this is not a limitation. In this case, all the pre-combustion chamber assemblies 12 are arranged at intervals along the front-rear direction d2 of the cylinder head, and the pre-combustion chamber assemblies 12 and ignition coils 13 are arranged in a one-to-one correspondence. In conjunction with the above, the ignition coils 13 are arranged at intervals along the length of the gap between the first cylinder head cover 141 and the second cylinder head cover 142.
[0049] Figure 8 yes Figure 1 A schematic diagram of a portion of the structure shown. Figure 9 yes Figure 8 The diagram shows the structure from a rear-view perspective.
[0050] Combination Figures 6-9 In some specific embodiments, the cylinder head 11 also includes an intake pipe 111, which is located at the top of the cylinder head 11 and at one end of the cylinder head in the front-rear direction d2. The intake pipe 111 extends along the left-right direction d1 of the cylinder head.
[0051] Specifically, the intake manifold 111 is part of the cylinder head 11. Other parts of the cylinder head 11 can be integrally formed with the intake manifold 111, in which case the cylinder head 11 essentially functions as a guide for airflow. The intake manifold 111 is located at one end of the cylinder head in the longitudinal direction d2, meaning it is positioned at the edge of the cylinder head 11. The intake manifold 111 extends along the lateral direction d1 of the cylinder head, meaning its length is approximately aligned with the longitudinal direction d2 of the cylinder head. However, this alignment is only approximate and allows for some deviation.
[0052] It should be understood that this configuration allows the intake pipe 111 to be integrated into the cylinder head 11, thereby reducing the space required for additional intake pipe 111 placement, making the engine structure more compact and facilitating a reduction in the overall size of the engine system.
[0053] Combination Figure 8 as well as Figure 9 In some specific embodiments, the vehicle's engine system also includes a turbocharger 17 and an intercooler 18. The turbocharger 17 is located on one side of the cylinder head in the left-right direction d1, and the intercooler 18 is located on the other side of the cylinder head in the left-right direction d1. The turbocharger 17 and the intercooler 18 are respectively connected to both ends of the intake manifold 111. The turbocharger 17 can be a turbocharger, which compresses external intake air to form high-temperature, high-pressure gas. The turbocharger 17 further introduces the high-temperature, high-pressure gas into the intercooler 18 through the intake manifold 111, whereby the intercooler 18 cools the gas. The intercooler 18 then introduces the cooled gas into the main combustion chamber of the engine for combustion assistance.
[0054] It should be understood that by arranging the turbocharger 17 and the intercooler 18 on both sides of the cylinder head in the left and right directions d1, the space on both sides of the cylinder head can be fully utilized, avoiding occupying too much space on the upper part of the cylinder head 11. This makes the arrangement of the various components of the engine system more reasonable, and to a certain extent, makes the arrangement of the engine system components more compact, thereby reducing the size of the engine system.
[0055] Based on the above settings, combined with Figure 9 In some specific embodiments, the vehicle's engine system 10 also includes an intake manifold 19, which is connected to and located below the intercooler 18, and is used to connect to the intake port of the cylinder.
[0056] Specifically, the top of the intake manifold 19 abuts against the top of the intercooler 18, thus allowing the intake manifold 19 to support the intercooler 18. At this time, the interior of the intake manifold 19 forms a large intake passage, the extension direction of which is consistent with the longitudinal direction d2 of the cylinder head. Multiple intake holes 112 can be provided on one side of the cylinder head 11, and the intake holes 112 communicate with the engine's combustion chamber. The intake manifold 19 covers the intake holes 112, thus connecting the intake holes 112 with the intake passage of the intake manifold 19. At this time, the gas discharged from the intercooler 18 enters the intake passage of the intake manifold 19, and further enters the intake holes 112.
[0057] It should be understood that in this embodiment, the intake manifold 19 has only one intake channel, thus realizing the integration and fusion of intake pipes corresponding to multiple intake ports 112, thereby reducing the space occupied by the intake pipes to a certain extent, and thus reducing the size of the engine system.
[0058] A second aspect of this application provides a vehicle including an engine system 10 as described in any of the above embodiments. The engine system 10 can be used directly to drive the vehicle or to drive a generator to generate electricity; no specific limitations are specified herein.
[0059] In summary, the engine system 10 and vehicle provided in this application include: a cylinder head 11, disposed at the top of the engine block; a pre-combustion chamber assembly 12, partially embedded in the cylinder head 11, with its height direction aligned with the height direction of the cylinder head 11, and the bottom of the pre-combustion chamber assembly 12 communicating with the main combustion chamber of the engine; and an ignition coil 13, disposed directly above the pre-combustion chamber assembly 12, with the bottom of the ignition coil 13 connected to the top of the pre-combustion chamber assembly 12 exposed outside the cylinder head 11, and the ignition coil 13 used for igniting the pre-combustion chamber assembly 12. Therefore, by embedding the pre-combustion chamber assembly 12 in the cylinder head 11 and placing the ignition coil 13 directly above the pre-combustion chamber assembly 12, a compact arrangement of the cylinder head 11, the pre-combustion chamber assembly 12, and the ignition coil 13 is achieved, thereby meeting the requirement of engine miniaturization.
[0060] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
