Optimization of Piston-Ring System for Reducing Lube Oil Consumption by CAE approach 2020-01-1339
Lube Oil Consumption (LOC) of one diesel engine has been found to be high. To resolve this problem, CAE analysis has been applied to analyze the piston motion, dynamics of piston ring, and characteristics of oil consumption. The root cause has been identified through CAE. The improved understanding has been applied to optimize the piston and piston ring. The optimized components have been tested. The experiment results are in good agreement with CAE predictions, and the oil consumption has been improved.
