Cause And Solution Of Abnormal Noise Of Engine Valve

Reasons for abnormal sound of engine valve: 1. The engine makes rhythmic "Da, Da" sound when idling. When the engine speed increases, the sound also becomes vague and noisy when the engine speed increases above medium speed. The engine temperature changes or the sound does not change during the stockout test; 2. Engine valve noise is mainly caused by the increase of engine operating noise, although it generally does not cause serious impact on other aspects of the engine. But the valve noise is mainly caused by the increase of valve clearance; 3. If the valve clearance is too large, it will have a direct impact on the opening and closing time and accuracy of the valve. Further, it may have a negative impact on the normal working performance of the engine. Therefore, if the problem of valve noise is obvious and serious, it is recommended to go to the specialized repair shop in time for further on-site maintenance and adjustment according to the actual situation.
