The increase in carbon dioxide emissions is a key factor leading to the warming of the Earth’s climate system and the intensification of the greenhouse effect. Internal combustion engines have a significant impact on carbon emissions. For internal combustion engines, friction is the main cause of energy loss, which reduces fuel utilization and increases carbon emissions. Therefore, it is necessary to reduce friction work of internal combustion engine. This work focuses on the friction pairs of piston pins and liners in internal combustion engines, and optimizes the surface technology of piston pins by comparing carburized and nitriding processes. The results show that the friction work of the nitrided piston pin is 8.9% lower than that of the carburized piston pin, and the wear of the liner is reduced by 10%. Therefore, surface nitriding process of piston pin is an effective way to reduce friction work and carbon emissions of internal combustion engines. |
