[0081] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0082] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0083] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.

[0084] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0085] The utility model provides a cylinder block of an engine. The engine can be used in a vehicle. The engine comprises a cylinder head assembly, an oil pan and a cylinder block. The cylinder head assembly is connected to a top surface 112 of the cylinder block. The oil pan is connected to a bottom surface 115 of the cylinder block for storing lubricating oil.

[0086] Please refer to Figures 1 to 6 , the cylinder block includes a cylinder block 110. The cylinder block 110 has a crankshaft hole 111. The axial direction of the crankshaft hole 111 is parallel to the first direction D1. The crankshaft of the engine is arranged in the crankshaft hole 111. The cylinder block 110 has an outer side surface. The outer side surface includes a first outer side surface 113 and a second outer side surface 114 facing each other. Along the third direction D3, the first outer side surface 113 is located at one end of the cylinder block 110, and the second outer side surface 114 is located at the other end of the cylinder block 110. In this way, the first outer side surface and the second outer side surface are spaced apart in the third direction D3. Along the third direction D3, the crankshaft hole 111 is located between the first outer side surface 113 and the second outer side surface 114.

[0087] The cylinder block 110 has a top surface 112 and a bottom surface 115 facing each other. Along the second direction D2, the top surface 112 is located at one end of the cylinder block 110, and the bottom surface 115 is located at the other end of the cylinder block 110. The top surface 112 is used to connect the cylinder head assembly. The bottom surface 115 is used to connect the oil pan. Along the second direction D2, the crankshaft hole 111 is located at the lower end of the cylinder block 110. In this way, the crankshaft hole 111 and the top surface 112 of the engine are spaced apart.

[0088] It should be noted that any two of the first direction D1, the second direction D2 and the third direction D3 intersect. For example, the first direction D1, the second direction D2 and any two of the third direction D3 are perpendicular. When the engine is installed in a vehicle, one of the first direction D1 and the third direction D3 is the width direction of the vehicle, and the other is the front-rear direction of the vehicle (the direction in which the vehicle moves forward or backward).

[0089] It can be understood that in an embodiment not shown, the second direction D2 may also be inclined to the horizontal direction.

[0090] Please continue to refer to Figures 1 to 6 , at least one transverse rib is provided on the outer side of the cylinder body 110. The length direction of the transverse rib extends along the first direction D1. The transverse rib is divided into a first side transverse rib 120 provided on the first outer side surface 113. The first side transverse rib 120 is divided into a first transverse rib 121 and a second transverse rib 122. The first transverse rib 121 and the second transverse rib 122 are arranged at intervals along the second direction D2. Along the second direction D2, the second transverse rib 122 is located to the side (e.g., below) of the first transverse rib 121.

[0091] On the projection plane 180 parallel to the first direction D1 and the second direction D1, the projection of at least one transverse rib and the projection of the upper edge 116 of the crankshaft hole 111 at least partially overlap. The upper edge 116 of the crankshaft hole 111 is the uppermost end of the inner wall surface of the crankshaft hole 111.

[0092] Specifically, the projection of the first transverse rib 121 on the projection plane 180 at least partially overlaps the projection of the upper edge 116 of the crankshaft hole 111. On the projection plane 180, the projection of the second transverse rib 122 covers the center of the projection of the inner wall surface of the crankshaft hole 111 along the second direction D2.

[0093] In this way, during the operation of the engine, most of the vibrations generated by the movement of the piston and the connecting rod are transmitted to the outside of the engine through the crankshaft hole 111. The provision of the first transverse rib 121 can effectively increase the strength of the portion of the cylinder block surrounding the crankshaft hole 111, thereby reducing the vibration of the cylinder block 110, improving the overall NVH (Noise, Vibration, Harshness) performance of the engine, and improving the overall strength and rigidity of the cylinder block.

[0094] The provision of the second transverse rib 122 can further increase the strength of the portion of the cylinder block surrounding the crankshaft hole 111 .

[0095] Herein, the length direction of a component extends along a direction such that the length direction of the component is parallel to or forms an acute angle with the direction. For example, the length direction of a transverse rib extends along a first direction D1 such that the length direction of the transverse rib is parallel to the first direction D1. Or the length direction of the transverse rib forms an acute angle with the first direction D1.

[0096] In this embodiment, the projection of at least one transverse rib and the projection of the upper edge 116 of the crankshaft hole 111 at least partially overlap, which can effectively increase the strength of the portion of the cylinder block surrounding the crankshaft hole 111, thereby reducing the vibration of the cylinder block 110, improving the overall NVH performance of the engine, and increasing the overall strength and rigidity of the cylinder block.

[0097] Preferably, the thickness of at least part of the transverse ribs along the second direction D2 ranges from 3 mm to 8 mm, thereby making the strength of the part of the transverse ribs high.

[0098] like Figures 1 to 6 As shown, the cylinder body 110 also includes a side mounting column. The side mounting column is located on the outer side surface and extends in a direction away from the outer side surface. The first outer side surface 113 and the second outer side surface 114 are both provided with a side mounting column. The end surface of the free end of the side mounting column (the end of the side mounting column away from the outer side surface connected thereto) is the outer end surface 133 of the side mounting column. The outer end surface 133 has a threaded hole. The side mounting column is used to connect the cylinder body and other components through the threaded hole. Specifically, the side mounting column includes a first side mounting column 131 arranged on the first outer side surface 113, and a second side mounting column 132 arranged on the second outer side surface 114. The first side mounting column 131 is located on the first outer side surface 113 and extends in a direction away from the first outer side surface 113. The second side mounting column 132 is located on the second outer side surface 114 and extends in a direction away from the second outer side surface 114. In this way, the strength of the cylinder body 110 is large.

[0099] Part of the transverse ribs are connected to the side mounting column. The transverse ribs are located between the outer end face and the outer side face of the side mounting column connected thereto. Specifically, the first side transverse rib 120 is located between the outer end face 133 and the first outer side face 113 of the first side mounting column 131 connected thereto. The second side transverse rib 160 described later is located between the outer end face 133 and the second outer side face 114 of the second side mounting column 132 connected thereto. In this way, it is convenient to fix the cylinder body by the side mounting column. In addition, the strength of the cylinder body 110 can be further increased.

[0100] Furthermore, the minimum distance between the transverse rib and the outer end surface 133 of the side mounting column connected thereto is in the range of 1 mm to 5 mm, thereby ensuring the strength of the side mounting column as much as possible.

[0101] Preferably, the minimum distance between at least part of the transverse ribs and the outer side surface connected thereto is greater than or equal to 40 mm. Specifically, the minimum distance between the first side transverse rib 120 and the first outer side surface 113 is greater than or equal to 40 mm. The minimum distance between the second side transverse rib 160 and the second outer side surface 114 described later is greater than or equal to 40 mm. As a result, the strength of the transverse ribs is high.

[0102] like Figure 2 and Figure 6As shown, the engine further includes a piston. The cylinder block 110 further includes a piston hole 117 and a cylinder block water jacket 118. The piston hole 117 is connected to the crankshaft hole 111. The piston is arranged in the piston hole 117. The cylinder block water jacket 118 is sleeved on the outer periphery of the piston hole 117. The cylinder block water jacket 118 is used to pass coolant to cool the portion of the cylinder block surrounding the piston hole 117. The first side transverse rib 120 is further divided into a third transverse rib 123. Along the second direction D2, the third transverse rib 123 is located to the side (e.g., above) of the first transverse rib 121. In this way, on the projection plane 180, the projection of the third transverse rib 123 is located above the projection of the upper edge 116 of the crankshaft hole 111. Along the second direction D2, the projection of the third transverse rib 123 and the projection of the lower edge 119 of the cylinder block water jacket 118 at least partially overlap.

[0103] During the operation of the engine, the cylinder body 110 is prone to stress concentration at the lower edge 119 of the cylinder water jacket 118. The third transverse rib 123 is provided to improve the strength of the cylinder body 110 at the lower edge 119 of the cylinder water jacket 118. In addition, during the operation of the engine, the heat generated by the combustion of the fuel is concentrated on the piston hole 117, and the heat load of the piston hole 117 is high, and the thermal deformation is large. Therefore, the provision of the third transverse rib 123 can increase the strength of the piston hole 117 and reduce the deformation of the piston hole 117.

[0104] Preferably, if Figure 2 As shown, along the second direction D2, the minimum distance between the third transverse rib 123 and the top surface 112 is L1. The stroke of the engine is S. The range of L1 / S is 0.5 to 0.7. Thus, the deformation of the piston hole 117 can be more effectively avoided.

[0105] It should be noted that the stroke of the engine is the distance the piston moves from the top dead center to the bottom dead center when the engine is working.

[0106] like Figure 5 and Figure 6 As shown, the first side transverse rib 120 is further divided into a fourth transverse rib 124. Along the second direction D2, the fourth transverse rib 124 is located to the side (e.g., below) of the third transverse rib 123. On the projection surface 180, the projection of the fourth transverse rib 124 is located between the projection of the upper edge 116 and the projection of the top surface 112 of the cylinder body 110. Thus, the deformation of the piston hole 117 can be more effectively avoided.

[0107] Preferably, if Figure 2 As shown, the minimum distance between the fourth transverse rib 124 and the top surface 112 is L2. The range of L2 / S is 0.9 to 1.1. Thus, the deformation of the piston hole 117 can be more effectively avoided.

[0108] like Figure 5 and Figure 6As shown, the cylinder block 110 further includes a main oil passage 140. The axis of the main oil passage 140 extends along the first direction D1. The oil pump described later can pump the lubricating oil in the oil pan to the main oil passage 140 via the high-pressure oil passage 146 described later. The main oil passage 140 is connected to the space where the crankshaft is located (the space in the crankshaft hole 111). In this way, when the engine is working, the lubricating oil can be transported to the crankshaft through the main oil passage 140 to lubricate the crankshaft. Please refer to Figure 2 , Figure 5 and Figure 6 , the first side transverse rib 120 is further divided into a fifth transverse rib 125. The fifth transverse rib 125 is located between the fourth transverse rib 124 and the first transverse rib 121. On the projection surface 180, the projection of the fifth transverse rib 125 and the projection of the inner wall surface of the main oil gallery 140 at least partially overlap. The projection of the fifth transverse rib 125 is located between the projection of the top surface 112 of the cylinder block 110 and the projection of the upper edge 116. Thus, the strength of the cylinder block 110 at the main oil gallery 140 can be increased.

[0109] Preferably, the maximum dimension of the transverse rib along the first direction D1 (eg, the dimension of the fifth transverse rib 125 along the first direction D1) is 7 / 10 to 9 / 10 of the dimension of the cylinder 110 along the first direction D1. Thus, the strength of the cylinder 110 can be further increased.

[0110] like Figure 2 and Figure 6 As shown, the cylinder body 110 further comprises longitudinal ribs. The longitudinal ribs extend in the second direction D2. The longitudinal ribs comprise first side longitudinal ribs 151 located on the first outer side surface 113. Thus, the strength of the cylinder body 110 can be further increased.

[0111] Preferably, the thickness of the longitudinal ribs (including the first side longitudinal ribs 151 and the second side longitudinal ribs 173 described later) along the first direction D1 ranges from 4 mm to 8 mm, thereby further increasing the strength of the cylinder body 110 .

[0112] Preferably, the minimum distance between the surface of the first side longitudinal rib 151 away from the center of the crankshaft hole along the third direction D3 and the first outer side surface 113 is greater than or equal to 40 mm. The minimum distance between the surface of the second side longitudinal rib 173 away from the center of the crankshaft hole along the third direction D3 and the second outer side surface 114 is greater than or equal to 40 mm. In this way, the strength of the cylinder block 110 can be further increased.

[0113] like Figures 1 to 6 As shown, the longitudinal ribs all extend to the top surface 112. Specifically, the first side longitudinal ribs 151 and the second side longitudinal ribs 173 described later all extend to the top surface 112. Thus, the strength of the cylinder body 110 can be further increased.

[0114] On the projection surface 180, the projection of the longitudinal ribs extends through the projection of the inner wall surface of the crankshaft hole 111. In this way, the longitudinal ribs extend to the crankshaft hole 111 (the portion of the cylinder block 110 surrounding the crankshaft hole 111). Specifically, the first side longitudinal ribs 151 and the second side longitudinal ribs 173 described later both extend to the crankshaft hole 111. In this way, the strength of the cylinder block 110 can be further increased.

[0115] like Figure 2 , Figure 4 and Figure 6 As shown, the cylinder body 110 also has an oil return passage 141 ( Figure 2 , the position of the oil return passage 141 is indicated by a dotted line frame). The axis of the oil return passage 141 extends along the second direction D2. The oil return passage 141 passes through both ends of the cylinder body 110 along the second direction D2. That is, the oil return passage 141 passes through the top surface 112 and the bottom surface 115 of the cylinder body 110. The oil return passage 141 is connected to the oil pan. In this way, when the engine is working, part of the lubricating oil in the oil pan is transported to the cylinder head assembly. At this time, at least part of the lubricating oil at the cylinder head assembly can return to the oil pan via the oil return passage 141. In this way, the lubricating oil can be recycled. The cylinder body 110 is provided with the oil return passage 141, and there is no need to set up another pipeline for oil return outside the cylinder body 110. The structure of the engine using the cylinder body 110 is simple.

[0116] Preferably, please continue to refer to Figure 2 , Figure 4 and Figure 6 , there are multiple oil return passages 141. There are multiple first side longitudinal ribs 151. The number of first side longitudinal ribs 151 is greater than the number of oil return passages 141. The multiple oil return passages 141 correspond to parts of the multiple first side longitudinal ribs 151 one by one. The oil return passages 141 are opened in the corresponding first side longitudinal ribs 151. Therefore, the structure of the cylinder body 110 is compact.

[0117] like Figure 4 and Figure 6 As shown, the cylinder body 110 further includes a plurality of piston holes 117. The plurality of piston holes 117 are all connected to the crankshaft hole 111. The plurality of piston holes 117 are sequentially arranged in the first direction D1. The plurality of piston holes 117 respectively penetrate to the top surface 112 of the cylinder body 110.

[0118] There are multiple oil return passages 141. The multiple oil return passages 141 are sequentially arranged along the first direction D1. In this way, the arrangement directions of the multiple piston holes 117 and the multiple oil return passages 141 are parallel. Therefore, the structure of the cylinder body 110 is compact.

[0119] Furthermore, part of the oil return passage 141 is located between two adjacent piston holes 117. Thus, the structure of the cylinder body 110 is compact.

[0120] like Figure 4 and Figure 6As shown, along the first direction D1, the portion of the cylinder body 110 located at the end of the piston hole 117 is provided with an oil return passage 141. Thus, the structure of the cylinder body 110 is compact.

[0121] like Figure 4 and Figure 6 As shown, the cylinder body 110 further includes a mounting hole 142. The mounting hole 142 is a threaded hole. The cylinder body 110 is connected to the cylinder head assembly through the mounting hole 142. Along the third direction D3, part of the mounting hole 142 is closer to the center of the piston hole 117 relative to the oil return passage 141. As a result, the structure of the cylinder body 110 is compact.

[0122] Please refer to Figure 2 , Figure 4 and Figure 6 , the oil return passage 141 includes a gradually expanding oil return passage 143. The gradually expanding oil return passage 143 includes a horizontal portion 144 and a vertical portion 145. The horizontal portion 144 is located on one side (upper side) of the vertical portion 145 close to the top surface 112. The horizontal portion 144 extends to the top surface 112 of the cylinder body 110. The maximum dimension of the horizontal portion 144 along the first direction D1 is greater than the maximum dimension of the vertical portion 145 along the first direction D1. The length direction of the horizontal portion 144 extends along the first direction D1. The length direction of the vertical portion 145 extends along the second direction D2. In this way, the length direction of the horizontal portion 144 and the length direction of the vertical portion 145 intersect. The horizontal portion 144 is connected to the vertical portion 145. As a result, the gradually expanding oil return passage 143 can more effectively return the lubricating oil to the oil pan.

[0123] Furthermore, the horizontal portion 144 and the vertical portion 145 form an L-shaped structure. Thus, the structure of the gradually expanding oil return passage 143 is simple.

[0124] Along the first direction D1 , the gradually expanding oil return passage 143 is closer to one end of the cylinder body 110 than the other oil return passages 141 .

[0125] Preferably, please refer to Figure 2 , Figure 4 and Figure 6, the engine also includes an oil cooler (not shown) and an oil pump (not shown). The cylinder block 110 also includes an oil cooling mounting portion 149. The oil cooling mounting portion 149 is used to connect the oil cooler. The oil cooling mounting portion 149 is located on the first outer side 113. The cylinder block 110 also includes a high-pressure oil passage 146. Along the second direction D2, the high-pressure oil passage 146 is located on the side (e.g., below) of the main oil passage 140. The high-pressure oil passage 146 is used to connect the main oil passage 140 through the oil cooler. The high-pressure oil passage 146 is connected to the oil pump. The oil pump pumps the lubricating oil in the oil pan to the high-pressure oil passage 146, and then after passing through the oil cooler, enters the main oil passage 140 and the cylinder head assembly. The lubricating oil entering the main oil passage 140 is delivered to the crankshaft to lubricate the crankshaft. The lubricating oil entering the cylinder head assembly is used to lubricate the valve assembly and then returns to the oil pan via the return oil passage 141. In this way, the pressure of the lubricating oil in the high-pressure oil passage 146 is greater than the pressure of the lubricating oil in the main oil passage 140 .

[0126] A high-pressure oil passage 146 is disposed between two adjacent oil return passages 141 along the first direction D1 . Thus, the structure of the cylinder body 110 is compact.

[0127] like Figure 2 As shown, the oil cooling mounting portion 149 has an inclined reinforcing rib 150. The inclined reinforcing rib 150 is a slender structure. The length direction (extension direction) of the inclined reinforcing rib 150 is inclined to the first direction D1. As a result, the strength of the cylinder block 110 is large.

[0128] like Figure 2 As shown, the oil cooling mounting portion 149 is constructed as a labyrinth structure. Thus, the strength of the cylinder block 110 is high.

[0129] Along the third direction D3, a high-pressure oil passage 146 is provided on the inner side of the oil cooling mounting portion 149 near the piston hole 117. Thus, the structure of the cylinder block 110 is compact.

[0130] like Figure 2 As shown, the high-pressure oil passage 146 includes a first high-pressure oil passage 147 and a second high-pressure oil passage 148 ( Figure 2 The positions of the first high-pressure oil passage 147 and the second high-pressure oil passage 148 are shown by the dotted line frame). The axis of the first high-pressure oil passage 147 extends along the second direction D2. The first high-pressure oil passage 147 is provided between two adjacent oil return passages 141 along the first direction D1. The first high-pressure oil passage 147 is located on the inner side of the oil cooling mounting portion 149 along the third direction D3 close to the center of the crankshaft hole 111. The axis of the second high-pressure oil passage 148 extends along the first direction D1. Along the second direction D2, the second high-pressure oil passage 148 is located on the side (e.g., below) of the first high-pressure oil passage 147 and is connected to the first high-pressure oil passage 147. As a result, the structure of the cylinder block 110 is compact.

[0131] Further preferably, the first high-pressure oil passage 147 and the second high-pressure oil passage 148 form an L-shaped structure. Thus, the structure of the cylinder body 110 is compact.

[0132] Please refer to Figure 1 , Figures 3 to 5 The transverse ribs further include a second side transverse rib 160. The second side transverse rib 160 is located on the second outer side surface 114 of the cylinder body 110. Thus, the strength of the cylinder body 110 is large.

[0133] The second side transverse rib 160 is divided into a ninth transverse rib 161. Along the second direction D2, the position of the ninth transverse rib 161 is slightly lower than the position of the third transverse rib 123. On the projection surface 180, the projection of the ninth transverse rib 161 and the projection of the lower edge 119 of the cylinder water jacket 118 at least partially overlap. Thus, the strength at the lower edge 119 of the cylinder water jacket 118 can be further increased.

[0134] like Figure 1 and Figure 3 As shown, the ninth transverse rib 161 is divided into a first sub-rib 162 and a second sub-rib 163 which are connected to each other. The length direction of the first sub-rib 162 and the length direction of the second sub-rib 163 intersect. The first sub-rib 162 and the second sub-rib 163 both extend to the timing end of the cylinder body 110 along the first direction D1. The timing end of the cylinder body 110 is provided with a timing cover mounting hole 175 for mounting the timing cover. Part of the timing cover mounting hole 175 extends into the first sub-rib 162 and the second sub-rib 163. The axial direction of the timing cover mounting hole 175 is parallel to the first direction D1, so that the timing cover provided on the timing member (timing chain or timing belt) is connected to the end face of the cylinder body 110 along the first direction D1 through the timing cover mounting hole 175. As a result, the strength of the connection between the cylinder body 110 and the timing cover is large.

[0135] More preferably, if Figure 1 and Figure 3 As shown, the ninth transverse rib 161 is further divided into a first main rib 164. The length direction of the first main rib 164 extends along the first direction D1. The length directions of any two of the first main rib 164, the first sub-rib 162 and the second sub-rib 163 intersect. The first sub-rib 162 and the second sub-rib 163 are both located at one end of the ninth transverse rib 161 along the first direction D1. One end of the first sub-rib 162 is connected to one end of the second sub-rib 163, and is connected to one end of the first main rib 164 along the first direction D1. Along the second direction D2, the other end of the first sub-rib 162 and the other end of the second sub-rib 163 are away from each other. In this way, the first sub-rib 162 and the second sub-rib 163 form a first V-shaped structure. As a result, the strength of the cylinder body 110 is large.

[0136] like Figure 1 and Figure 3As shown, the second side transverse rib 160 is further divided into a tenth transverse rib 165 located at the side (eg, below) of the ninth transverse rib 161. Thus, the strength of the cylinder body 110 can be further increased.

[0137] Preferably, the tenth transverse rib 165 is divided into a third sub-rib 166 and a fourth sub-rib 167 connected to each other. The length direction of the third sub-rib 166 intersects the length direction of the fourth sub-rib 167. The third sub-rib 166 and the fourth sub-rib 167 both extend to the timing end of the cylinder body 110 along the first direction D1.

[0138] Part of the timing cover mounting hole 175 extends into the third sub-rib 166 and the fourth sub-rib 167. Thus, the strength of the connection between the cylinder block 110 and the timing cover is large.

[0139] More preferably, if Figure 1 and Figure 3 As shown, the tenth transverse rib 165 is further divided into a second main rib 168. The length direction of the second main rib 168 extends along the first direction D1. The length directions of any two of the first main rib 164, the first sub-rib 162 and the second sub-rib 163 intersect. The third sub-rib 166 and the fourth sub-rib 167 are both located at one end of the tenth transverse rib 165 along the first direction D1. One end of the third sub-rib 166 is connected to one end of the fourth sub-rib 167, and is connected to one end of the second main rib 168 along the first direction D1. Along the second direction D2, the other end of the third sub-rib 166 and the other end of the fourth sub-rib 167 are away from each other. In this way, the third sub-rib 166 and the fourth sub-rib 167 form a second V-shaped structure. As a result, the strength of the cylinder body 110 is large.

[0140] Preferably, the distance between the tenth transverse rib 165 and the bottom dead center of the piston along the second direction D2 ranges from 18 mm to 22 mm. Thus, the structure of the cylinder body 110 is compact.

[0141] like Figure 1 and Figure 3 As shown, the second side transverse rib 160 is further divided into a sixth transverse rib 169. Along the second direction D2, the sixth transverse rib 169 is located on the side of the tenth transverse rib 165 away from the ninth transverse rib 161. Along the second direction D2, the sixth transverse rib 169 is located between the lower edge of the piston hole 117 and the center of the crankshaft hole 111. As a result, the strength of the cylinder block 110 is large.

[0142] Preferably, the distance between the surface of the sixth transverse rib 169 away from the center of the crankshaft hole 111 along the third direction D3 and the second outer side surface 114 is in the range of 10 mm to 15 mm. Thus, the sixth transverse rib 169 has great strength.

[0143] like Figure 1 and Figure 3As shown, the second transverse rib 122 further includes a seventh transverse rib 170. Along the second direction D2, the seventh transverse rib 170 is located to the side (eg, below) of the sixth transverse rib 169. The seventh transverse rib 170 is connected to the second side mounting column 132. Thus, the cylinder body 110 has a high strength.

[0144] like Figure 1 and Figure 3 As shown, the second transverse rib 122 also includes an eighth transverse rib 171. Along the second direction D2, the eighth transverse rib 171 and the second transverse rib 122 are located at substantially the same position. Along the second direction D2, the eighth transverse rib 171 is located to the side (e.g., below) of the seventh transverse rib 170. On the projection plane 180, the projection of the eighth transverse rib 171 covers the center of the projection of the inner wall surface of the crankshaft hole 111 along the second direction D2. As a result, the strength of the cylinder block 110 at the crankshaft hole 111 is high.

[0145] like Figure 1 and Figure 3 As shown, the second outer side surface 114 of the cylinder body 110 is further provided with a second side longitudinal rib 173. The length direction of the second side longitudinal rib 173 extends along the second direction D2. Thus, the strength of the cylinder body 110 is high.

[0146] Preferably, the cylinder body 110 further has a ventilation passage 174 . Figure 3 The position of the ventilation passage 174 is shown by the dotted line frame. One end of the ventilation passage 174 passes through one end (top surface 112) of the cylinder body along the second direction D2. The other end of the ventilation passage 174 is connected to the crankshaft hole 111. The ventilation passage 174 is used to allow air flow to ventilate the internal space of the crankshaft hole 111, thereby adjusting the pressure of the internal space of the crankshaft hole 111. As a result, the structure of the cylinder body 110 is compact.

[0147] There are multiple ventilation channels 174. There are multiple second side longitudinal ribs 173. The number of second side longitudinal ribs 173 is greater than the number of ventilation channels 174. The multiple ventilation channels 174 correspond to the parts of the multiple second side longitudinal ribs 173 one by one. The ventilation channels 174 are opened in the corresponding second side longitudinal ribs 173. Therefore, the structure of the cylinder body 110 is compact.

[0148] Preferably, the cylinder body 110 is provided with mounting holes 142 on both sides of the ventilation passage 174 along the first direction D1. Thus, the structure of the cylinder body 110 is compact.

[0149] Preferably, on the projection surface 180, both sides of the projection of the inner wall surface of the ventilation passage 174 along the first direction D1 have projections of the inner wall surface of the mounting hole 142. Thus, the structure of the cylinder body 110 is compact.
