What does the carbon tank do?
The role of carbon tank: the tank produces steam at room temperature, the fuel evaporation emission system is to introduce steam into combustion and prevent volatilization into the atmosphere, reduce air pollution, plays an important role is the active carbon tank storage device. The carbon tank is also part of the gasoline evaporation control system, which is designed to prevent fuel vapor from entering the atmosphere when the engine stops running. This device not only reduces exhaust emissions, but also reduces fuel consumption. Carbon canister related failure: 1. Abnormal noise of car running. When the car is not running at idle speed, sometimes it will hear the rattling sound. When the vehicle encounters this situation, the first thing to check is the carbon tank solenoid valve of the vehicle. If it is the sound issued by the solenoid valve, there is no need to worry about it. Because the carbon tank solenoid valve will produce intermittent switching action when the vehicle throttle is opened, so it will produce this sound, which is a normal phenomenon. 2. Step on the accelerator of the azole car, the gasoline smell inside the car is larger. In this case, it is necessary to check whether there is damage to the carbon tank system pipeline. If there is damage, gasoline steam will enter the car with the pipeline, so it will smell the gasoline inside the car. 3. The engine idle speed fluctuates and the vehicle acceleration is weak. This situation may be caused by the blockage of the air inlet and filter of the carbon tank, and the outside air is not easy to enter the carbon tank, so that the mixture of oxygen sensor is too strong, the engine reduces the amount of fuel injection, resulting in idle speed increase and acceleration. 4. Engine flameout is not easy to start. In this case, it is necessary to check whether the solenoid valve of the carbon tank is closed. The accumulation of oil and gas in the carbon tank leads to the rest of the oil and gas directly into the atmosphere, polluting the environment. On the contrary, if there is always open state, it will cause the hot car is too strong mixture, and the vehicle is not easy to start after extinguishing.
