[0002] A cylinder liner is provided at one end of the diesel engine body. The cylinder liner is an important component of the engine. Its structure is cylindrical. The connection between the cylinder liner and the engine body is usually a 90-degree bend structure, which has a large stress concentration. The reciprocating motion of the piston inside the cylinder liner has a large impact force. Not only does its structure need to meet high-intensity working conditions, but it also requires good heat dissipation capabilities in a high-temperature working environment.

[0007] Furthermore, a plurality of vertical heat dissipation ribs are arranged on the outer wall of the cylinder sleeve above the push rod sleeve hole of the machine body. The outer wall of the cylinder sleeve at the push rod sleeve hole also receives additional push rod impact force, and it is more reasonable to make a reinforcement structure here.

[0013] Furthermore, the engine body and the cylinder sleeve are integrally die-cast, and the structure is more stable.
[0014] The advantages of the utility model are that the heat dissipation and strength of the diesel engine body are improved at the cylinder liner, which not only ensures the stability of the overall operation of the diesel engine body in a high-temperature and high-pressure working environment, but also improves the strength at the stress concentration point of the diesel engine body structure, thereby improving the quality of the product and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 It is the front view of the utility model;
[0017] Figure 3 It is a schematic diagram of the utility model from another angle.
[0018] In the figure, there is a machine body 1, a cylinder sleeve 2, a transverse heat sink 3, a vertical heat sink rib 4, and a push rod sleeve hole 5. DETAILED DESCRIPTION
[0019] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:
[0020] like Figure 1 , 2 As shown in Figure 3, the present scheme provides a reinforced diesel engine body, including a body body 1, on which a cylinder liner 2 is arranged. In the present embodiment, the body body 1 and the cylinder liner 2 are integrally die-cast, and the cylinder liner 2 is cylindrical, which is a support body for the reciprocating motion of the piston. There is friction between the piston and the cylinder liner 2 during the motion, which will generate a great impact force on the connection between the cylinder liner 2 and the body body 1. The integrated structure is conducive to improving its strength.
[0021] The outer wall of the cylinder liner 2 is provided with a plurality of transverse heat sinks 3 and a plurality of vertical heat sink ribs 4. The plurality of transverse heat sinks 3 extend radially outward along the cylinder liner 2. The plurality of transverse heat sinks 3 are arranged at equal intervals and parallel to each other. The transverse heat sinks 3 are distributed on the outer wall of the cylinder liner 2 and extend outward, thereby increasing the heat dissipation area of the outer wall of the cylinder liner 2, which is beneficial for the diesel engine body to work under high temperature and high pressure.
[0022] A plurality of vertical heat dissipation ribs 4 are arranged along the axial direction of the cylinder sleeve 2, and the vertical heat dissipation ribs 4 are consistent with the direction of the piston movement, so as to better enhance the side wall strength of the cylinder sleeve 2. Specifically, a plurality of vertical heat dissipation ribs 4 are arranged on the outer wall of the cylinder sleeve 2 above the push rod sleeve hole 5 of the machine body 1. More specifically, there are 4 vertical heat dissipation ribs. The vertical heat dissipation ribs 4 not only play a role in heat dissipation, but also play a role in strengthening the strength between the cylinder sleeve 2 and the machine body 1.
[0023] A plane is arranged on the outer wall of the cylinder sleeve 2 in the direction of the push rod sleeve hole 5, and a plurality of vertical heat dissipation ribs 4 are arranged on the plane, because the force here includes not only the impact force of the piston but also the impact force of the push rod, so the arrangement here is more reasonable. The plurality of vertical heat dissipation ribs 4 are arranged at equal intervals and parallel to each other.
[0024] The outer wall of the cylinder liner 2 is provided with transverse heat dissipation fins 3 and vertical heat dissipation ribs 4, and the heat dissipation and strength of the diesel engine body are improved at the cylinder liner 2, which not only can meet the heat dissipation capacity in a high-temperature working environment, but also can enhance the strength of the cylinder liner 2, can resist the impact caused by the piston and the stress concentration caused by the structure, so that the diesel engine body can work more stably and the service life is extended.
[0025] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
