Failure Analysis of Cylinder Wear for a New Diesel Engine and its Optimization
Abnormal increase of crankcase pressure and large gas channeling occurred during a new diesel engine development.After fault reappearance and analysis,it is confirmed that the failure was caused by abnormal wear of the cylinder.Through composition testing,performance testing and thermo-mechanical coupling CAE comparative analysis,it was confirmed that the high thermal load and poor lu-brication conditions led to the cylinder wear.The optimization design was put forward based on the failure analysis.Durability test results show that the optimized cylinder is in good condition and there is no prob-lem of cylinder polishing.
