Description

Technical Field

[0001] This application relates to the field of engine technology, and more particularly to a cylinder head assembly, an engine, and a vehicle having the same. Background Technology

[0002] The rational layout of the engine compartment is receiving increasing attention. In related technologies, the layout of the engine compartment is often quite challenging, requiring a more rational design. Utility Model Content

[0003] This application provides a cylinder head device designed to improve the problem of unreasonable space arrangement in the engine compartment.

[0004] This application also proposes an engine that includes the cylinder head assembly described above.

[0005] This application also proposes a vehicle that includes the aforementioned engine.

[0006] The cylinder head device according to an embodiment of this application includes: a body; a cover and an oil pump bracket, wherein the cover and the oil pump bracket are both disposed on the upper side of the body, and a portion of the cover overlaps a portion of the oil pump bracket.

[0007] According to the embodiments of this application, the cylinder head assembly, by having both the cover and the oil pump bracket located on the upper side of the main body, reduces the space occupied by the cylinder head assembly in the front-rear direction, effectively reducing the engine size and facilitating a more rational layout of the engine compartment. By partially overlapping the cover with the oil pump bracket, on the one hand, the structure of the cylinder head assembly becomes more compact, improving the sealing reliability of the cylinder head assembly and facilitating the assembly of the cover. On the other hand, compared to having the entire outer edge of the cover extend downwards to the main body, having a portion of the cover overlap with the oil pump bracket allows the lower end of the outer edge of the cover to be spaced apart from the main body. This allows the outer edge of the oil pump bracket to be used to connect the portion of the cover overlapping the oil pump bracket to the main body, relatively reducing the production and processing costs of the cover and the overall production cost of the cylinder head assembly.

[0008] In addition, the cylinder head device according to this application may also have the following additional technical features:

[0009] In some embodiments of this application, the projection of the oil pump bracket onto a plane perpendicular to the vertical direction is a first projection, and the first projection is a triangle.

[0010] In this application, by projecting the oil pump bracket onto a plane perpendicular to the vertical direction as a triangle, the space occupied by the oil pump bracket in the horizontal direction can be reduced, the volume of the high-cost oil pump bracket can be reduced, and the volume of the low-cost cover can be increased, thereby minimizing the cost of the cylinder head assembly.

[0011] In some embodiments of this application, the outer edge of the oil pump bracket includes a first segment, a second segment, and a third segment connected in sequence, and the outer edge of the cover has a fourth segment, which overlaps the oil pump bracket and extends along one of the first segment, the second segment, and the third segment.

[0012] In this application, by extending the fourth section of the cover along one of the first, second, and third sections of the oil pump bracket, the overlap between the cover and the oil pump bracket can be minimized as much as possible while ensuring the sealing performance of the cylinder head assembly, thereby reducing the manufacturing cost of the cylinder head assembly.

[0013] In some embodiments of this application, the lower end of the outer edge of the cover has a groove, and a first sealing member is provided in the groove. A portion of the first sealing member is located between the cover and the body, and the remaining portion of the first sealing member is located between the cover and the oil pump bracket.

[0014] In this application, a first sealing element is provided on the outer edge of the cover. Part of the first sealing element is located between the cover and the main body, and part is located between the cover and the oil pump bracket. This can prevent impurities from entering the cylinder head assembly, reduce the maintenance frequency of the cylinder head assembly, extend the service life of the cylinder head assembly, and reduce the number of parts in the cylinder head assembly, thereby reducing the assembly steps and assembly difficulty. The groove can position the first sealing element, facilitating its installation, preventing it from shifting or wobbling, and ensuring the sealing performance of the first sealing element between the cover and the main body, and between the cover and the oil pump bracket. This further reduces the probability of impurities entering the cylinder head assembly, lowers the maintenance frequency, and extends the service life of the cylinder head assembly.

[0015] In some embodiments of this application, a sealant is provided between the outer edge of the oil pump bracket and the body.

[0016] In this application, a sealant is provided between the outer edge of the oil pump bracket and the body, which can achieve a seal between the oil pump bracket and the body. On the one hand, it can prevent impurities from entering the cylinder head assembly, reduce the maintenance frequency of the cylinder head assembly, and extend the service life of the cylinder head assembly. On the other hand, it can prevent engine oil leakage, ensure engine performance and reliability, reduce engine safety hazards, and reduce engine maintenance frequency.

[0017] In some embodiments of this application, the cover is made of plastic and the oil pump bracket is made of metal.

[0018] In this application, by using a plastic cover, which is lightweight and low-cost, the weight of the cylinder head assembly can be reduced, which is beneficial to the lightweighting of the engine and reduces the production cost of the cylinder head assembly. The oil pump bracket is made of metal, which can improve the reliability and stability of the oil pump bracket, extend the service life of the oil pump bracket, and ensure the support, fixation and protection effect of the oil pump bracket on the oil pump.

[0019] In some embodiments of this application, the cover has a first flow channel that extends in a vertical direction and has an open upper end. The body has a second flow channel, one end of which is connected to the lower end of the first flow channel. The end of the second flow channel facing away from the first flow channel is open and located on the side wall of the body.

[0020] In this application, a first flow channel is provided on the cover, extending vertically with its upper end open. A second flow channel is provided on the main body, with one end connected to the lower end of the first flow channel and the other end of the second flow channel open and located on the side wall of the main body. This allows liquid from the top of the engine to be discharged from the side wall of the cylinder head assembly, meeting the engine's drainage requirements and maximizing the discharge of liquid from the top of the engine. This prevents water from seeping into the spark plug holes over time, reducing the probability of spark plug rust or failure and ensuring the normal operation of the vehicle.

[0021] In some embodiments of this application, a second seal is provided between the cover and the body, the second seal surrounding the first flow channel and the second flow channel.

[0022] In this application, a second sealing element is provided between the cover and the main body. The second sealing element surrounds the first flow channel and the second flow channel, which can seal the end face of the cover and the main body in contact, preventing some of the liquid in the first flow channel from flowing into the first cavity defined by the main body and the cover, ensuring that all the liquid flowing out of the first flow channel flows into the second flow channel, preventing the liquid from entering the first cavity and affecting other components in the engine, and ensuring the reliability and safety of the engine.

[0023] This application also provides an engine having the above-described embodiments.

[0024] According to the engine embodiment of this application, by providing the aforementioned cylinder head device, and with both the cover and the oil pump bracket located on the upper side of the main body, the space occupied by the cylinder head device in the front-rear direction can be reduced, effectively shrinking the engine volume and facilitating a reasonable layout of the engine compartment. By partially overlapping the cover with the oil pump bracket, on the one hand, the structure of the cylinder head device can be made more compact, improving the sealing reliability of the cylinder head device and facilitating the assembly of the cover. On the other hand, compared to the outer edge of the cover extending entirely downwards to the main body, having part of the cover overlap with the oil pump bracket allows the lower end of the outer edge of the cover to be spaced apart from the main body. This allows the outer edge of the oil pump bracket to be used to connect the portion of the cover overlapping the oil pump bracket to the main body, relatively reducing the production and processing costs of the cover and the overall production cost of the cylinder head device.

[0025] This application also provides a vehicle having the above-described embodiments.

[0026] According to the vehicle embodiment of this application, by providing the aforementioned engine, and with both the cover and the oil pump bracket located on the upper side of the main body, the space occupied by the cylinder head assembly in the front-rear direction can be reduced, effectively shrinking the engine volume and facilitating a more rational layout of the engine compartment. By partially overlapping the cover onto the oil pump bracket, on the one hand, the structure of the cylinder head assembly can be made more compact, improving the sealing reliability of the cylinder head assembly and facilitating the assembly of the cover. On the other hand, compared to the outer edge of the cover extending entirely downwards to the main body, having part of the cover overlap the oil pump bracket allows the lower end of the outer edge of the cover to be spaced apart from the main body. This allows the outer edge of the oil pump bracket to be used to connect the portion of the cover overlapping the oil pump bracket to the main body, relatively reducing the production and processing costs of the cover and the overall production cost of the cylinder head assembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The cylinder head device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the cylinder head device 100 according to an embodiment of the present invention includes a body 1, a cover 2, and an oil pump bracket 3.

[0040] Specifically, see the attached document. Figure 1As shown, the cylinder head assembly 100 is used in an engine (e.g., a direct injection hybrid engine). The body 1 is used to seal the top of the cylinder and, together with the piston top and cylinder wall, forms a combustion chamber. The cover 2 is used to cover and seal the body 1 to prevent impurities from entering. The oil pump bracket 3 is used to support, fix, and protect the oil pump 30, ensuring a stable fuel supply and safe system operation. Both the cover 2 and the oil pump bracket 3 are located on the upper side of the body 1. The cover 2 and the body 1 define a first cavity, and the oil pump bracket 3 and the body 1 define a second cavity. Compared to the prior art where some oil pump brackets are located on the rear side of the body, this invention places the oil pump bracket 3 on the upper side of the body 1, which reduces the cylinder head assembly 100 in the front-rear direction (e.g., ...). Figure 1 The space occupied by the oil pump 30 (as shown) effectively reduces the size of the engine and avoids interference between the oil pump 30 and other components such as the motor in the engine compartment.

[0041] Further, see attached document. Figure 2 As shown, part of the cover 2 overlaps with part of the oil pump bracket 3. On the one hand, this makes the structure of the cylinder head device 100 more compact, improves the sealing reliability of the cylinder head device 100, and facilitates the assembly of the cover 2. On the other hand, compared to the outer edge of the cover 2 extending downward to the body 1, having part of the cover 2 overlap with part of the oil pump bracket 3 allows the lower end of part of the outer edge of the cover 2 to be spaced apart from the body 1. This allows the outer edge of part of the oil pump bracket 3 to be used to connect the part of the cover 2 overlapping the oil pump bracket 3 to the body 1, which can relatively reduce the production and processing cost of the cover 2 and reduce the overall production cost of the cylinder head device 100.

[0042] Furthermore, since the oil pump bracket 3 has higher strength and higher cost, compared to having part of the oil pump bracket 3 overlap with part of the cover 2, having part of the cover 2 overlap with part of the oil pump bracket 3, the cost of the cylinder head device 100 can be reduced as much as possible while ensuring the installation reliability of the oil pump bracket 3.

[0043] According to the embodiment of the present invention, the cylinder head device 100, with both the cover 2 and the oil pump bracket 3 located on the upper side of the body 1, can reduce the space occupied by the cylinder head device 100 in the front-rear direction, effectively reducing the size of the engine and facilitating a reasonable layout of the engine compartment. By partially overlapping the cover 2 onto the oil pump bracket 3, on the one hand, the structure of the cylinder head device 100 can be made more compact, improving the sealing reliability of the cylinder head device 100 and facilitating the assembly of the cover 2. On the other hand, compared to the outer edge of the cover 2 extending downward to the body 1, having part of the cover 2 overlap the oil pump bracket 3 allows the lower end of the outer edge of part of the cover 2 to be spaced apart from the body 1. This allows the outer edge of part of the oil pump bracket 3 to be used to connect the part of the cover 2 overlapping the oil pump bracket 3 to the body 1, which can relatively reduce the production and processing cost of the cover 2 and the overall production cost of the cylinder head device 100.

[0044] In some embodiments of this utility model, reference is made to the appendix. Figure 2 As shown, the oil pump bracket 3 is perpendicular to the vertical direction (e.g., Figure 1 The projection on the plane shown is the first projection, which is a triangle. It can be understood that the oil pump bracket 3 and the cover 2 are arranged in the horizontal direction and together cover the upper side of the body 1. Since the oil pump bracket 3 is an aluminum alloy part and the cover 2 is a plastic part, by limiting the projection of the oil pump bracket 3 on the horizontal plane to a triangle, the space occupied by the oil pump bracket 3 in the horizontal direction can be reduced, the volume of the high-cost oil pump bracket 3 can be reduced, and the volume of the low-cost cover 2 can be increased, thereby reducing the cost of the cylinder head device 100 as much as possible.

[0045] In a further embodiment of this utility model, reference is made to the appendix. Figure 2 As shown, the outer edge of the oil pump bracket 3 includes a first segment 31, a second segment 32, and a third segment 33 connected in sequence. The outer edge of the cover 2 has a fourth segment 21, which overlaps the oil pump bracket 3 and extends along one of the first segment 31, the second segment 32, and the third segment 33. The cover 2 and the oil pump bracket 3 together cover the upper side of the body 1, which can minimize the overlap between the cover 2 and the oil pump bracket 3 while ensuring the sealing of the cylinder head device 100, thereby reducing the manufacturing cost of the cylinder head device 100.

[0046] In a specific example, see Appendix Figure 2 As shown, the projection of the oil pump bracket 3 onto a plane perpendicular to the vertical direction is a right triangle. The first segment 31, the second segment 32, and the third segment 33 are the three sides of the triangle, with the first segment 31 and the second segment 32 being the two legs of the right triangle, and the third segment 33 being the hypotenuse. The fourth segment 21 extends along the length of the third segment 33 (see attached diagram). Figure 2Extending in the direction shown (a), since the third segment 33 is the longest side among the first segment 31, the second segment 32 and the third segment 33, extending the fourth segment 21 along the length direction of the third segment 33 can make the length of the fourth segment 21 relatively longer. This allows the fourth segment 21 to be connected to the body 1 by utilizing as much of the outer edge of the oil pump bracket 3 as possible, which can further reduce the production and processing cost of the cover 2 and reduce the production cost of the entire cylinder head device 100.

[0047] In some embodiments of this utility model, in conjunction with the reference appendix Figure 1 and attached Figure 2 As shown, the lower end of the outer edge of the cover 2 has a groove that extends along the outer edge of the cover 2. A first sealing element 22 is provided in the groove. Part of the first sealing element 22 is located between the cover 2 and the main body 1, and the remaining part of the first sealing element 22 is located between the cover 2 and the oil pump bracket 3. The first sealing element 22 can simultaneously ensure the seal between the cover 2 and the main body 1 and between the cover 2 and the oil pump bracket 3. It can prevent impurities from entering the cylinder head assembly 100, reduce the maintenance frequency of the cylinder head assembly 100, extend the service life of the cylinder head assembly 100, and reduce the number of parts of the cylinder head assembly 100, reduce the assembly process of the cylinder head assembly 100, and reduce the assembly difficulty of the cylinder head assembly 100.

[0048] It should be noted that by providing a groove at the lower end of the outer edge of the cover 2 and placing the first seal 22 in the groove, the groove can position the first seal 22, facilitating its installation and preventing it from shifting or shaking. This ensures the sealing performance of the first seal 22 between the cover 2 and the main body 1, and between the cover 2 and the oil pump bracket 3, further reducing the probability of impurities entering the cylinder head assembly 100, reducing the maintenance frequency of the cylinder head assembly 100, and extending its service life.

[0049] In some embodiments of this utility model, a sealant is provided between the outer edge of the oil pump bracket 3 and the body 1. The sealant extends along the outer edge of the oil pump bracket 3 to achieve a seal between the oil pump bracket 3 and the body 1. On the one hand, it can prevent impurities from entering the cylinder head device 100, reduce the maintenance frequency of the cylinder head device 100, and extend the service life of the cylinder head device 100. On the other hand, it can prevent engine oil leakage, ensure engine performance and reliability, reduce engine safety hazards, and reduce engine maintenance frequency.

[0050] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2As shown, the cover 2 and / or the oil pump bracket 3 are fixed to the body 1 by fasteners 11, which can ensure the reliability of the connection between the cover 2 and the body 1, and between the oil pump bracket 3 and the body 1, and facilitate the disassembly and assembly of the cover 2 and the oil pump bracket 3.

[0051] It is understandable that only the cover 2 and the main body 1 are connected by fastener 11, while the oil pump bracket 3 and the main body 1 are connected by other means. Alternatively, only the oil pump bracket 3 and the main body 1 are connected by fastener 11, while the cover 2 and the main body 1 are connected by other means. Or, both the cover 2 and the main body 1, and the oil pump bracket 3 and the main body 1 are connected by fastener 11.

[0052] In some embodiments of this utility model, the cover 2 is made of plastic, which is lightweight and low-cost, reducing the weight of the cylinder head assembly 100 and contributing to engine weight reduction. This reduces the production cost of the cylinder head assembly 100 and the procurement cost of the engine. Furthermore, the oil pump bracket 3 is made of metal. Metal has high tensile strength and mechanical properties, enabling it to withstand greater loads and stresses. This improves the reliability and stability of the oil pump bracket 3, extends its service life, and ensures the effective support, fixation, and protection of the oil pump 30.

[0053] Preferably, the oil pump bracket 3 is made of aluminum alloy, and the body 1 is also made of aluminum alloy. Aluminum alloy has a high specific strength, which can ensure the structural strength of the oil pump bracket 3 and the body 1 while minimizing their weight, which is beneficial for the lightweighting of the engine.

[0054] In some embodiments of this utility model, in conjunction with the reference appendix Figure 1 and attached Figure 2 As shown, the cover 2 has a first flow channel 23, which extends vertically and is open at its upper end. The body 1 has a second flow channel 12, one end of which is connected to the lower end of the first flow channel 23. The end of the second flow channel 12 facing away from the first flow channel 23 is open and located on the side wall of the body 1. Liquid on the upper side of the cover 2 (such as sewage entering when the vehicle passes through a flooded section, residual water from car washing, etc.) can enter the first flow channel 23 from the upper end of the first flow channel 23, then flow from the first flow channel 23 to the second flow channel 12, and finally flow out of the cylinder head device 100 from the end of the second flow channel 12 facing away from the first flow channel 23. This allows the liquid on the top of the engine to be discharged from the side wall of the cylinder head device 100, meeting the engine's drainage requirements, discharging as much liquid as possible from the top of the engine, preventing water from seeping into the spark plug holes over time, reducing the probability of spark plug rusting or failure, and ensuring the normal operation of the vehicle.

[0055] It is understood that the end of the second flow channel 12 facing away from the first flow channel 23 is open and located on the side wall of the body 1. The end of the second flow channel 12 facing away from the first flow channel 23 can be located on the front side wall of the body 1, or on the rear side wall of the body 1, or on the left side wall of the body 1, or on the right side wall of the body 1. No further restrictions are imposed here.

[0056] In a specific example, referring to the appendix Figure 1 and attached Figure 2 As shown, the second flow channel 12 includes a first sub-flow channel 121 and a second sub-flow channel 122. The first sub-flow channel 121 and the second sub-flow channel 122 are arranged and connected in the vertical direction. The first sub-flow channel 121 extends in the vertical direction, and its upper end is opposite to and connected to the lower end of the first flow channel 23. The second sub-flow channel 122 extends in the front-rear direction, and its front end is connected to the lower end of the first sub-flow channel 121. The rear end of the second sub-flow channel 122 is open and located on the rear side wall of the main body 1. It can be understood that the liquid at the top of the engine can enter the first flow channel 23 from its upper end, and then flow into the first sub-flow channel 121 from its lower end. After passing through the first sub-flow channel 121 and the second sub-flow channel 122 in sequence, the liquid is discharged from the engine from the rear end of the second sub-flow channel 122.

[0057] In a further embodiment of this utility model, the inner diameter of the first flow channel 23 is greater than 8mm. On the one hand, this can increase the drainage speed of the liquid at the top of the cover 2 by the first flow channel 23, so that as much liquid as possible can be discharged through the first flow channel 23 at the same time. On the other hand, when the liquid at the top of the cover 2 carries dust and other impurities into the first flow channel 23, the probability of blockage of the first flow channel 23 can be reduced, thus avoiding affecting the normal discharge of the liquid.

[0058] Furthermore, the inner diameter of the second flow channel 12 is greater than 8mm. On the one hand, this can increase the drainage speed of the liquid from the first flow channel 23 in the second flow channel 12, so that as much liquid as possible can be discharged through the second flow channel 12 at the same time. On the other hand, it can reduce the probability of blockage of the second flow channel 12 when the liquid at the top of the cover 2 carries dust and other impurities into the second flow channel 12, thus avoiding affecting the normal discharge of the liquid.

[0059] It should be noted that the inner diameter of the second flow channel 12 is greater than or equal to the inner diameter of the first flow channel 23. This ensures that all the liquid flowing out of the first flow channel 23 flows into the second flow channel 12, preventing some of the liquid in the first flow channel 23 from flowing into the first cavity defined by the body 1 and the cover 2. This also prevents the liquid from affecting other components inside the engine, ensuring the reliability and safety of the engine.

[0060] Preferably, the inner diameters of the first flow channel 23, the first sub-flow channel 121, and the second sub-flow channel 122 are all equal, which can ensure that all the liquid flowing out of the first flow channel 23 flows into the first sub-flow channel 121, and facilitates the sealing between the cover 2 and the main body 1, ensuring that the liquid at the top of the cover 2 can flow into the first flow channel 23, the first sub-flow channel 121, and the second sub-flow channel 122 in sequence.

[0061] In a further embodiment of this utility model, a second sealing element is provided between the cover 2 and the main body 1. The second sealing element surrounds the first flow channel 23 and the second flow channel 12. The second sealing element can seal the end face of the cover 2 and the main body 1 that are in contact, preventing some of the liquid in the first flow channel 23 from flowing into the first cavity defined by the main body 1 and the cover 2, ensuring that all the liquid flowing out of the first flow channel 23 flows into the second flow channel 12, preventing the liquid from entering the first cavity and affecting other components in the engine, and ensuring the reliability and safety of the engine.

[0062] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 As shown, the inner wall of the end of the second flow channel 12 opposite to the first flow channel 23 is provided with an internal thread 123. The internal thread 123 allows the engine lifting lug to be installed in the second flow channel 12, so that the second flow channel 12 can serve as a drainage channel and also have the function of installing the lifting lug. This reduces the number of bolt bosses on the body 1 without affecting the drainage function of the cylinder head device 100, thereby reducing the manufacturing cost of the cylinder head device 100 and reducing the manufacturing difficulty of the cylinder head device 100.

[0063] Understandably, during engine disassembly and assembly, the lifting lug is installed on the second flow channel 12, so that the external thread of the lifting lug engages with the internal thread 123 of the second flow channel 12. At this time, the second flow channel 12 serves as a mounting hole for the lifting lug, facilitating engine disassembly and assembly. After the engine is assembled, the lifting lug can be removed from the second flow channel 12, which then serves as a drainage channel for the liquid at the top of the engine to drain. In a specific example, the end of the second flow channel 12 facing away from the first flow channel 23 is an M10 threaded hole.

[0064] This utility model also proposes an engine having the cylinder head device 100 of the above embodiments.

[0065] According to the embodiment of this utility model, the engine, by providing the aforementioned cylinder head device 100, and by having both the cover 2 and the oil pump bracket 3 located on the upper side of the main body 1, can reduce the space occupied by the cylinder head device 100 in the front-rear direction, effectively reducing the size of the engine and facilitating a reasonable layout of the engine compartment. By partially overlapping the cover 2 onto the oil pump bracket 3, on the one hand, the structure of the cylinder head device 100 can be made more compact, improving the sealing reliability of the cylinder head device 100 and facilitating the assembly of the cover 2. On the other hand, compared to the outer edge of the cover 2 extending entirely downwards to the main body 1, having part of the cover 2 overlap onto the oil pump bracket 3 allows the lower end of the outer edge of part of the cover 2 to be spaced apart from the main body 1. This allows the outer edge of part of the oil pump bracket 3 to be used to connect the part of the cover 2 overlapping onto the oil pump bracket 3 to the main body 1, which can relatively reduce the production and processing cost of the cover 2 and the overall production cost of the cylinder head device 100.

[0066] This utility model also proposes a vehicle having the engine described in the above embodiments.

[0067] According to the vehicle of this utility model embodiment, by providing the above-mentioned engine, and by having both the cover 2 and the oil pump bracket 3 located on the upper side of the body 1, the space occupied by the cylinder head assembly 100 in the front-rear direction can be reduced, effectively reducing the size of the engine and facilitating a reasonable layout of the engine compartment. By partially overlapping the cover 2 onto the oil pump bracket 3, on the one hand, the structure of the cylinder head assembly 100 can be made more compact, improving the sealing reliability of the cylinder head assembly 100 and facilitating the assembly of the cover 2. On the other hand, compared to the outer edge of the cover 2 extending downwards to the body 1, having part of the cover 2 overlap the oil pump bracket 3 allows the lower end of the outer edge of part of the cover 2 to be spaced apart from the body 1. This allows the outer edge of part of the oil pump bracket 3 to be used to connect the part of the cover 2 overlapping the oil pump bracket 3 to the body 1, which can relatively reduce the production and processing cost of the cover 2 and reduce the overall production cost of the cylinder head assembly 100.

[0068] The cylinder head device 100, engine, and other components and operations of the vehicle according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
