The NVH optimization of high performance diesel engine needs new concept of development. There were a few tries to Include NVH features on the stage of concept design. We could use proper NVH features at concept stage by the improvement of previous engine’s weak points and test results of major competitor in the market. The 2ND generation engine needs to have not only quiet sound but also pleasant sound characteristics. We applied some sound quality index to get better sound features. We tried to consider vehicle interior noise at engine test bench. We developed a competitive diesel engine which was accomplished by using efficient develop process and approaching new area of NVH.
