19 Magotan idling with snoring.

The abnormal noise when the car is idling may be caused by engine failure. There are many reasons for engine failure, which need to be checked one by one.

The most common problem when the engine is idling is jitter. Idle jitter may be caused by dirty throttle or excessive carbon deposition. If these factors lead to abnormal engine sound, it is recommended that the owner check the working conditions of spark plugs, high-voltage lines and ignition coils. In addition, it may also be caused by the high working temperature of the engine.

If the ignition angle of the engine is too early, the fuel combustion in the engine is incomplete and the internal pressure of the engine is high. In this state, it will not only cause abnormal noise of the engine, but also cause jitter in the working process.

If the engine works for a long time, it will produce carbon deposit. If these carbon deposits are not cleaned for a long time, the compression ratio of the engine will increase, and the carbon deposits will adhere to the internal parts of the engine for a long time, which will affect the power of the car to a certain extent, and will also lead to an increase in fuel consumption and affect the comfort of the car.

During the operation of the engine, it will produce relatively high temperature, which will also lead to the wear or aging of internal parts.
