Engine idle noise,UEFA TV have you also encountered it? As drivers, we all know very well that different models have different characteristics. But one thing is the same, that is, you should pay attention to all aspects of abnormal noise when driving. When your car makes strange noises from time to time when idling, it is likely to be caused by engine problems. What is the engine idling noise?First, let's understand what engine idling is. The idle state means that no liquid (oil, water, coolant, etc.) explodes in the combustion chamber of the engine, resulting in the inability of combustion gas to be discharged, and the vehicle can only remain in place. Abnormal sound refers to a sound that is different from the normal operating state, usually due to a problem with a part that needs to be repaired or replaced. Most engine idling noises are caused by the noise generated by friction of mechanical parts, and may also be caused by pipeline or system failures. What factors cause the engine to make abnormal noise at idle? 1. Fuel supply problem: The engine can only run by supplying enough fuel. If the oil supply is insufficient or the oil supply pipe is blocked, it will cause abnormal engine noise. Two. Air emission problem: Due to the accumulation of garbage in the engine exhaust pipe, it will lead to incomplete fuel combustion and may cause abnormal engine noise.3. Cylinder block aging: often drive long distances, or use for too long, the engine cylinder liner and piston ring are aging, and it is easy to make abnormal noises when idling, which needs to be overhauled. Four. Ignition system failure: There is an abnormal sound when the vehicle cannot start or idle, which may be due to the failure of the ignition system, which needs to be checked and repaired. 5. Air flowmeter problem: The air flowmeter is responsible for monitoring the amount of oxygen required when the air passes through the engine combustion. If the component fails, it will cause the engine to fail to run normally and make abnormal noises. How to eliminate the abnormal noise of engine idling? 1. Troubleshooting and reasonable maintenance: If your car has an engine idling noise, please troubleshoot the fault in time and carry out appropriate maintenance. Regular replacement of oil, air filter, spark plug and other vehicle parts can extend the service life of the engine and the whole vehicle.Two. Engine maintenance: If you find abnormal engine noise when idling, it is best to go to a professional maintenance station for inspection and related work. Regular maintenance and maintenance play a crucial role in the health of the vehicle. 3. Safe driving: Maintaining your vehicle engine can better ensure driving safety and reduce the possibility of accidents. In a word, if you find that the car engine has "abnormal noise" in the idling state, it must be eliminated in time, and it is very important to maintain the vehicle. At the same time, pay attention to safety when driving, ensure the safety of yourself and passengers, drive well, and take care of the car.
