AI Technical Summary

Technical Problem

The prior art is difficult to effectively reduce the friction power consumption of the crank link mechanism, resulting in an increase in the overall friction loss of the engine and fuel consumption, which in turn affects the emission of carbon dioxide and other pollutants.

Method used

The friction between the connecting rod and the piston is reduced by providing a first abrasion reducing coating, including a diamond-like coating, on the surface of the pin, thereby reducing frictional power consumption of the crank link mechanism.

Benefits of technology

It effectively reduces the friction power consumption of the crank link mechanism, improves the mechanical efficiency of the engine, and reduces fuel consumption and carbon dioxide emissions.

Abstract

The invention relates to a crank mechanism and an engine. The crank mechanism comprises a piston provided with a first connecting hole; a second connecting hole is formed in one end of the connecting rod, and the second connecting hole and the first connecting hole are coaxial; and the pin shaft is arranged in the first connecting hole and the second connecting hole in a penetrating mode, and a first anti-attrition coating is arranged on the surface of the pin shaft. According to the crank mechanism and the engine, friction between the connecting rod and the piston can be effectively reduced by arranging the first anti-friction coating on the surface of the pin shaft, so that friction power consumption of the crank connecting rod mechanism is reduced, the overall friction loss of the engine can be effectively reduced, fuel consumption can be further reduced, and the service life of the engine is prolonged. Therefore, the effect of reducing the emission of carbon dioxide and other pollutants is achieved.
