摘要
为改善某四缸增压直喷汽油发动机NVH(Noise Vibration and Harshness),通过优化正时系统相关零部件,进行试验测试,发现优化正时链条及机油泵链条结构、优化正时罩盖对噪音改善明显。
In order to improve the Noise Vibration and Harshness （NVH） of a four cylinder turbocharged direct injection gasoline engine, the timing system related parts and components are optimized, experiment test are earned out. It is found that optimization of timing chain and oil pump chain structure and the timing cover cap can obviously improve the noise.
