Description

Technical Field

[0001] The utility model relates to the technical field of pistons, in particular to a cast iron sheet mechanism for improving piston performance. Background Art

[0002] When the engine is in working condition, the friction loss of the piston is one of the most important factors affecting the mechanical efficiency of the internal combustion engine. The overall friction loss of the internal combustion engine accounts for approximately 4% to 15% of the total energy, and the piston assembly accounts for 40% to 45% of the friction loss, of which the piston accounts for 25% to 47% of the friction loss. Reducing the friction loss of the piston is one of the ways to improve the mechanical efficiency of the internal combustion engine.

[0003] After the pin seat and the pin hole are installed as a whole, the performance of the existing piston will be reduced after a long period of operation, resulting in the stability of the piston pin seat position and the tensile strength of both sides of the pin hole, which will lead to the decline of piston performance and further affect the efficiency of the internal combustion engine. In view of the above problems, it is important to design a cast iron sheet mechanism to improve the performance of the piston. Utility Model Content

[0004] The utility model aims to provide a cast iron sheet mechanism for improving piston performance to solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a cast iron sheet mechanism for improving piston performance, comprising a body and an iron sheet, wherein the body is fixedly provided with an iron sheet, the iron sheet is symmetrically installed, and the iron sheet is embedded in the body through casting technology.

[0006] Preferably, the iron sheet is attached to the inner wall of the body.

[0007] Preferably, the iron sheet is made of steel.

[0008] The beneficial effect of the utility model is that the cast iron sheet mechanism for improving piston performance greatly improves the overall performance of the piston through the iron sheet set, which is mainly reflected in the stability of the piston pin seat position and the tensile performance on both sides of the pin hole, while improving the comfort of the piston's appearance and the mechanical efficiency of the piston.
