19 What is the reason for the abnormal idling sound of Yinglang three cylinders?

The reasons for abnormal idle noise of the three cylinders of Pacific Auto Network 19 Yinglang are: poor oil quality, abnormal valve sound, aging or loosening of engine foot glue, and abnormal noise of carbon canister solenoid valve. It is normal for the carbon canister solenoid valve to make abnormal noise when working, and it does not need to be handled.

1, the reason of engine oil, inferior engine oil or long-term failure to change engine oil, insufficient engine oil, etc. , may lead to the increase of friction between the valve and the guide tube and the hydraulic tappet, thus making all kinds of sounds in the engine louder.

2. The valve is abnormal and the engine is behind the car? Dadada? Ring, this is the sound of the valve door, especially after the car is cold, because the oil pressure has not gone up, the valve has not been lubricated in place, and it will naturally be fine in a while.

3, machine foot glue aging or loose. Foot glue is a rubber block between the engine and the frame. Its function is to reduce the vibration and buffer when the engine works and fix the engine. Once these feet are aged or loose, the engine will shake, which will appear in serious cases? Da da? Abnormal sound, this kind only needs to change the foot glue of a new machine.

4. The solenoid valve of the carbon canister makes abnormal noise when working. The function of the canister solenoid valve is to open the solenoid valve installed between the canister and the intake manifold after the engine is started, and then bring the adsorbed gasoline vapor and air into the cylinder for combustion. This not only reduces emissions, but also reduces fuel consumption.
