Abstract: | The goal of reducing the load and wear of each part in engine andimproving the performance of whole engine can be realized through some improving measures such as a structure with long connecting rod and short piston and the platform cross hatch honing technology for cylinder block to reduce the mass of moving parts and improve the lubrication level. The advantages of improving design are verified and proved through kinetic computing and analysis of results from road tests and test bench. |
