What is the disappearance of idling refueling?

The solenoid valve of carbon canister is faulty, so it is recommended to replace it.

The function of the carbon canister solenoid valve is to open the solenoid valve installed between the carbon canister and the intake manifold when the engine is started, and the gasoline vapor adsorbed in the carbon canister is brought into the cylinder to participate in combustion together with air. This not only reduces emissions, but also reduces fuel consumption. The component will also make a crisp click when working.

Precautions:

If the engine idles for a long time, the throttle opening will be very small, and the injector will spray high-concentration engine oil to ensure the engine running. Therefore, idling itself is more likely to cause carbon deposition than driving or running at high speed. If it is idling for a long time, the carbon deposition of the engine will definitely be more serious.

When the engine is idling, due to the relatively low temperature and pressure in the cylinder, the preparation time for fuel ignition is prolonged, and at this time, the tightness of the cylinder is reduced, which is easy to produce cylinder knocking and shorten the service life of the engine.
