Diesel engine’s cam is the important part to ensure diesel engine’s performance
its main failure is abrasion.When making the 1105W direct-spurt diesel
it was found that cam shaft that made according to the traditional technology can’t meet the requirement of inlet and exhaust cam and oil pump cam at the same time
the abrasion of oil pump cam is serious.Oil pump cam’s wear resistance can be improved remarkablely through the technology of remelting hardening +surface quenching + low temperature tempering.
