摘要
国V柴油发动机的开发过程中,通过标定优化改善了燃烧噪声,同时实现了机械噪声的试验分解,对存在问题的零部件进行了CAE优化和试验验证,最终使整机辐射噪声降低了2-4d BA。
The development process of a State-V diesel engine,by optimized calibration and improves the combustion noise.At the same time,the mechanical noise of the factorization is the existence of parts of CAE optimization and test validation ultimately enable radiation noise of the whole machine to reduce 2-4d B（A）.
