slight shaking of engine idling (slight shaking of engine,High-tech exports HS code categorization strange sound when idling) steamThe car engine is the core of the whole car system. Its normal operation is not only related to the performance and service life of the car, but also directly related to the safe driving of the car. However, when car owners use cars, there are often some unsatisfactory situations. Among them, the slight shaking of the engine and the abnormal sound when idling are a relatively common situation. If this situation is not repaired in time, it is likely to cause serious damage to the engine and even affect the service life of the car. Next, let's discuss the reasons and repair methods for the slight shaking of the engine at idle speed and the abnormal sound during idling. 1. Analysis of the reasons. There may be many reasons for the slight shaking of the engine at idle speed and the abnormal sound during idling. The following are relatively common: (1) The air filter is dirty and the engine intake system needs to replace the air filter frequently.If the air filter is not replaced in time, it will be blocked, so that the insufficient air cannot enter the engine through the air filter to burn, resulting in slight shaking of the engine idling and abnormal noise during idling. ( 2) Ignition system failure The normal operation of the engine ignition system is the basis for engine cycle operation. If the ignition system fails, it will affect the normal operation of the engine, resulting in slight shaking of the engine idling and abnormal noise during idling. ( 3) Throttle valve failure The throttle valve is the main part that controls the air intake of the engine. If the throttle valve fails, it will lead to insufficient engine air intake, causing slight shaking of the engine idling and abnormal noise when idling. ( 4) The computer regulator of the engine regulator faulty vehicle controls the working state of the engine, including the amount of fuel entry, the timing of ignition, etc.If the engine regulator fails, it will make the engine operation unstable, resulting in slight shaking of the engine idling and abnormal noise during idling. Two. The following plan should be adopted to repair the slight shaking of the engine and abnormal noise during idling: (1) The owner of the air filter should replace the air filter regularly to ensure that the air burning air of the engine is clean and sufficient, and avoid slight shaking of the engine idling and abnormal noise during idling. Life. ( 2) Repair the ignition system. If the engine ignition system fails, it should be repaired as soon as possible to ensure the normal operation of the engine. Common ignition system failures include aging of high-voltage lines, expired spark plugs, low battery power, etc. If you don't know how to repair it, you should go to a professional car repair shop for help in time.(3) Repair the throttle valve. If you find a fault in the throttle valve, it needs to be repaired or replaced in time. If you have no experience, you should not replace it by yourself. You should go to a qualified car repair shop for maintenance. ( 4) To repair the fault of the engine regulator, you should go to a professional car repair factory in time. Because repairing the engine regulator requires professional equipment, it is impossible to repair by yourself. In a word, when it is found that the car engine is slightly shaking at idle speed and there is a strange sound when idling, the owner should adopt the above repair plan in time to repair it to ensure the normal operation of the engine and extend the service life of the car. At the same time, the engine should also be maintained regularly to ensure that the car is in good working condition for a long time.
