The emission standards getting higher and higher, which causes the car requiring to be improved.The piston and connecting rod assembly is a part of which need improvement. It is principal to the automobile engine, which structure would have a directly impact on the engine¡¯s power, the fuel economy and the exhaust emission. In addition, because the unrenewable resources is gradually diminishing, the durability of the piston and connecting rod assembly also should be increase. Combining considerable amount of literatures with the trend of development of the piston and connecting rod assembly at home and abroad, this paper carried on the design to the 6105 engine's piston and connecting rod assembly. Considered each kind of load the assembly parts enduring, this paper design the assembly parts individually. The primary coverage includes choseing the compatible structure and the proper material for the piston,the piston ring,the piston pin and the connecting rod, calculating the important size parameter, examinating the intensity of the dangerous spot ,such as the piston pin and the rod. the main purpse is to ensure the structure of the assembly is reasonable,has a lightweight, durable and reliable, thereby enhances the fuel economy and reduces the exhaust emission of the 6105 engine. In the daily life,it has a certain practiality.
