摘要
为改善某四缸增压柴油发动机的NVH(Noise Vibration and Harshness),通过优化正时系统进行台架效果验证,结果表明:优化正时系统罩盖,调节皮带张紧力,增加惰轮对整机低频噪声改善效果明显。
For improving the NVH（Noise Vibration and Harshness）of 4-cylinder turbo-charged diesel engine, a research and test of optimizing the timing system proves that the low frequency noise can decrease through improving the timing case, the tension force of the belt and adding the tensioner.
