| Abstract: | To d eal with the scuffing issue of piston pin bearing of a two-cylinder diesel engine, the piston pin oval deformation was calculated and the piston pin bearing fit clearances were analyzed to find out the root cause. The scuffing issue was fixed by increasing the clearances between piston pin and small end bush. The solution was validated by engine bench test with good result. The experience can be referenced. |
