一、初步诊断,判定异响对发动机的影响程度1.如果声响在发动机低速运转时显得轻微单纯,在高速运转时轰鸣平稳均匀,在加速和减速时圆滑过度,则为正常声响。2.如果声响仅在怠速时存在,转速提高后即自行消失,在整个使用过程中声响又无明显的变化。这属于危害不大的异响,允许暂时存在,待适当时机再行修理。
First, the initial diagnosis, to determine the extent of abnormal sound effects on the engine 1. If the sound in the engine running at low speed seems a bit simple, the roar at high speed smooth and uniform, smooth and excessive acceleration and deceleration, the normal sound. 2. If the sound only exists when idling, the speed will disappear on its own, and there will be no obvious change in the sound during the whole process. This is a less damaging anomaly, allowing for a temporary existence, pending further repair at an appropriate time.
