[0029] Reference below Figure 1-Figure 2A cylinder block 10 for an engine 20 according to an embodiment of the present application is described. The cylinder block 10 includes a cylinder block body 11 and a reinforcement member 14 .
[0030] The cylinder block body 11 is provided with a first cylinder group 12 and a second cylinder group 13 spaced apart in a first direction and extending obliquely away from each other. The first cylinder group 12 is formed with a first cylinder hole 121 , and the second cylinder group 13 is formed with a second cylinder hole 131 .
[0031] The reinforcement 14 is disposed on the cylinder body 11 and located between the first cylinder group 12 and the second cylinder group 13 .

[0032] One end of the reinforcement member 14 is adjacent to the first cylinder hole 121 , and the other end of the reinforcement member 14 is adjacent to the second cylinder hole 131 .
[0033] With rising living standards and the pursuit of a better quality of life, consumers are increasingly demanding high-power, high-torque engines. While the high-speed rotation of the crankshaft generates high-energy excitation, it also makes the noise around the engine more pronounced, negatively impacting the vehicle's overall quietness. To reduce radiated noise around the engine, most current designs increase the thickness of the cylinder block's top and bottom plates to improve NVH performance, or enhance the vehicle's NVH performance by adding a soundproofing cover. However, these approaches increase weight and component complexity, creating significant challenges in vehicle assembly, maintenance, and management.
[0034] In this regard, Figure 1 As shown, the present application proposes a cylinder block 10 for an engine 20. The cylinder block 10 may include a cylinder block body 11 and a reinforcement 14. A first cylinder group 12 and a second cylinder group 13 may be disposed on the cylinder block body 11. The first cylinder group 12 and the second cylinder group 13 may be spaced apart in a first direction, and the free ends of the first cylinder group 12 and the second cylinder group 13 may further extend obliquely away from each other. In a specific embodiment, the cylinder block 10 may be configured in a V-shape. It should be noted that the first cylinder group 12 and the second cylinder group 13 may be integrally formed with the cylinder block body 11.
[0035] Furthermore, a first cylinder hole 121 may be formed on the first cylinder group 12, and the first cylinder hole 121 may extend toward the interior of the first cylinder group 12. A second cylinder hole 131 may be formed on the second cylinder group 13, and the second cylinder hole 131 may extend toward the interior of the second cylinder group 13. The first cylinder hole 121 and the second cylinder hole 131 may be used to install the cylinder. A reinforcement member 14 may be provided on the cylinder body 11, and the reinforcement member 14 may be located between the first cylinder group 12 and the second cylinder group 13. One end of the reinforcement member 14 may be connected to the first cylinder group 12, and the other end of the reinforcement member 14 may be connected to the second cylinder group 13. Specifically, the reinforcement 14 can be constructed as a reinforcement rib, and one end of the reinforcement 14 can be adjacent to the first cylinder hole 121, and the other end of the reinforcement 14 can be adjacent to the second cylinder hole 131. Since the cylinder will generate vibration and noise when working, the reinforcement 14 can be provided to improve the overall strength of the cylinder block 10, reduce the vibration amount of the cylinder block 10, and improve the NVH performance. For example, the use of the reinforcement 14 can reduce the top noise of the cylinder block 10 by 2 decibels. Compared with the existing technology, the cylinder block 10 can also reduce the number of parts and management costs of the engine 20, improve the performance and cost advantages of the product, and improve the competitiveness of the product.
[0036] In short, the cylinder block 10 for the engine 20 of the embodiment of the present application has a cylinder block body 11 and a reinforcement 14, and the cylinder block body 11 is provided with a first cylinder group 12 and a second cylinder group 13, and the first cylinder group 12 and the second cylinder group 13 are respectively formed with a first cylinder hole 121 and a second cylinder hole 131, and the reinforcement 14 can be provided on the cylinder block body 11 and located between the first cylinder group 12 and the second cylinder group 13, and the two ends of the reinforcement 14 in the first direction are respectively connected to the first cylinder group 12 and the second cylinder group 13, and the two ends of the reinforcement 14 in the first direction are respectively adjacent to the first cylinder hole 121 and the second cylinder hole 131, thereby improving the overall structural strength and rigidity of the cylinder block 10, reducing the vibration and noise of the cylinder block 10, and improving the NVH performance.
[0037] like Figure 1 As shown, in some embodiments of the present application, the first cylinder bore 121 and the second cylinder bore 131 are staggered in the first direction. It should be noted that the center of the first cylinder bore 121 and the center of the second cylinder bore 131 are located on different horizontal lines in the first direction, and the shortest distance from the center of the first cylinder bore 121 to the reinforcement 14 is the same as the shortest distance from the center of the second cylinder bore 131 to the reinforcement 14. It can be understood that the reinforcement 14 can be set at the center of the first cylinder bore 121 and the second cylinder bore 131 in the second direction to ensure that the distances from the reinforcement 14 to the center of the first cylinder bore 121 and the center of the second cylinder bore 131 are the same, so that the reinforcement 14 can more effectively improve the top stiffness of the cylinder block 10.
[0038] like Figure 1 As shown, in some embodiments of the present application, the number of first cylinder holes 121 can be multiple, and the multiple first cylinder holes 121 can be spaced apart on the first cylinder group 12 in the second direction. The number of second cylinder holes 131 can be multiple, and the multiple second cylinder holes 131 can be spaced apart on the second cylinder group 13 in the second direction, wherein the multiple second cylinder holes 131 correspond to the multiple first cylinder holes 121 in the first direction and are staggered. In a specific embodiment, the number of first cylinder holes 121 can be 3, the number of second cylinder holes 131 can be 3, and the second direction can be orthogonal to the first direction.
[0039] Furthermore, one of the first cylinder holes 121 and the second cylinder holes 131 corresponding to it and staggered along the first direction are defined as a group, the number of the reinforcement members 14 can be multiple, and the multiple reinforcement members 14 can be spaced apart in the second direction. By arranging multiple reinforcement members 14, the rigidity of the top of the cylinder block 10 can be further improved, wherein each reinforcement member 14 is respectively arranged corresponding to a group of first cylinder holes 121 and second cylinder holes 131. It can be understood that the distance between each reinforcement member 14 and the center of the circle of the corresponding group of first cylinder holes 121 and second cylinder holes 131 is the same. The above arrangement method can be used to provide a reinforcement member 14 at each cylinder, thereby reducing the vibration of the cylinder block 10 and improving the NVH performance.
[0040] In some embodiments of the present application, the thickness of the reinforcement member 14 is d, which satisfies the relationship: 4mm≤d≤6mm. That is, the thickness of the reinforcement member 14 can be any value between 4mm and 6mm. For example, the thickness of the reinforcement member 14 can be, but is not limited to, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc. If the thickness of the reinforcement member 14 is too large, the overall weight will increase, which is not conducive to lightweighting the cylinder block 10. If the thickness of the reinforcement member 14 is too small, it will be difficult to produce prototypes of the cylinder block 10. Therefore, setting the thickness of the reinforcement member 14 within the above range can improve the overall strength of the cylinder block 10, reduce the vibration of the cylinder block 10, and improve NVH performance.
[0041] like Figure 1 As shown, in some embodiments of the present application, a mounting groove 15 extending inward may be formed on the cylinder block body 11, and the mounting groove 15 may be located between the first cylinder group 12 and the second cylinder group 13. The mounting groove 15 may be used to install a thermostat. By arranging the mounting groove 15 on the cylinder block body 11, the overall structural layout of the engine 20 may be made more compact. A reinforcement portion 16 may also be provided at one end of the cylinder block body 11 in the second direction. The reinforcement portion 16 may further improve the overall structural strength and rigidity of the cylinder block 10, reduce the vibration and noise of the cylinder block 10, and improve the NVH performance.
[0042] like Figure 2 As shown, the engine 20 according to another embodiment of the present application is briefly described below.
[0043] The engine 20 according to the embodiment of the present application is provided with a cover 21 and the cylinder block 10 of the above embodiment. The cover 21 is provided at one end of the cylinder block 10 in the first direction and connected to the cylinder block 10. Optionally, the cover 21 and the cylinder block 10 can be detachably connected by screws or bolts.
[0044] Since the engine 20 of the embodiment of the present application is provided with a cover 21 and the cylinder block 10 of the above-mentioned embodiment, the engine 20 is provided with a first cylinder group 12 and a second cylinder group 13 on the cylinder block body 11, and the first cylinder group 12 and the second cylinder group 13 are respectively formed with a first cylinder hole 121 and a second cylinder hole 131. The reinforcement 14 can be provided on the cylinder block body 11 and located between the first cylinder group 12 and the second cylinder group 13. The two ends of the reinforcement 14 in the first direction are respectively connected to the first cylinder group 12 and the second cylinder group 13, and the two ends of the reinforcement 14 in the first direction are respectively adjacent to the first cylinder hole 121 and the second cylinder hole 131, thereby improving the overall structural strength and rigidity of the cylinder block 10, reducing the vibration and noise of the cylinder block 10, and improving the NVH performance of the engine 20.
[0045] like Figure 2 As shown, in some embodiments of the present application, at least part of the cylinder block 10 and the cover 21 are detachably connected and form a mounting cavity 211. Specifically, at least part of the cylinder block 10 and the cover 2 can be detachably connected by screws or bolts. The mounting cavity 211 can be used to install an oil pump. Compared with placing the oil pump inside the oil pan, by installing the oil pump in the mounting cavity 211, the length of the oil passage connecting the oil pump and the main oil passage of the cylinder block 10 can be shortened, making the overall layout of the engine 20 more compact. Furthermore, the cover 21 can also be provided with a notch 212, and the cylinder body 11 can be formed with a mounting hole 111. The mounting hole 111 can be used to install an oil pump solenoid valve. The notch 212 can be arranged opposite the mounting hole 111 to form an installation space for the oil pump solenoid valve, reducing the overall weight of the engine 20 while facilitating the installation of the oil pump solenoid valve, making the overall layout of the engine 20 more compact.

The reinforcement 14 can be provided on the cylinder block body 11 and located between the first cylinder group 12 and the second cylinder group 13.
