Carbon Canister FAQ
1. What is a carbon canister?
Carbon canister, the full name of "activated carbon adsorption canister", is a canister filled with activated carbon. It is a device that collects gasoline vapor and reuses it. It can reduce the emission of gasoline evaporation in the carburetor of the car's fuel tank. It is also a device with a low presence among various configurations of the car.
Automotive emissions are a major contributor to urban air pollution. Exhaust emissions are effectively controlled by the use of exhaust gas catalysts. To limit the emissions of evaporated gasoline vapor, activated carbon canisters are used.
ACC Activated Carbon Product is used in the fuel tank to adsorb the hydrocarbon molecules in the pores and on the surface of the activated carbon, preventing hydrocarbon emissions into the environment. It has passed the test certificates from the world’s major car manufacturers and canister carbon manufacturers. This series of products accord with the emission control requirements of China VI Emission Standard and Euro VI Emission Standard.
2. Where is the carbon filter canister located in the car?
The carbon filter canister is usually installed between the gasoline tank and the engine. The reason why a carbon filter canister is added to the fuel tank is because the fuel is easy to evaporate. The volatilization temperature of gasoline is very low, and it can volatilize at dozens of degrees below zero. The higher the temperature, the stronger the volatilization performance. If the fuel tank is sealed, it will be burst by volatile gasoline vapor at normal temperature, so a vent must be designed.
However, directly discharging gasoline evaporation into the air outside the car is not only wasteful, but also affects the air quality and even risks starting a fire. Therefore, a carbon canister is added to the fuel tank, and the filtered air is discharged from the carbon canister to achieve constant pressure inside and outside the fuel tank.
3. How does the automotive carbon canister work?
The working operation of the automotive carbon canister is as follows: when the engine operating solenoid valve is turned on, the engine inhales the fuel vapor in the fuel tank and the vapor adsorbed by the active material into the intake pipe; When the engine is not working or the solenoid valve is not turned on, the steam in the fuel tank enters the activated carbon canister and is absorbed by the active material;
