Activated carbon tank

Activated carbon tank: A small black tank installed on the right side of the rear of the car. It is filled with activated carbon and connected to the fuel tank. Its function is to absorb gasoline vapor.

Gasoline is a volatile fuel. The fuel in the fuel tank will evaporate quickly and increase the pressure inside the fuel tank. When the pressure reaches a certain value, it will cause certain dangers. Therefore, people tried to find ways to balance the pressure. At first, they made the fuel tank cap. Pressure limiting valve. When the pressure is higher than a certain value, the pressure limiting valve opens and sends gasoline vapor into the atmosphere. Later, from the perspective of saving fuel and protecting the environment, people set up carbon canisters. The inside of the canister is made of Filled with highly adsorbent activated carbon, excess fuel vapor in the fuel tank is no longer discharged into the atmosphere, but is introduced into the activated carbon canister through a pipe. Metal processing WeChat has good content and deserves attention. Activated carbon absorbs fuel vapor. When the car is started, the solenoid valve of the activated carbon canister opens in time and pours the absorbed fuel vapor back into the intake manifold to achieve the purpose of saving fuel and environmental protection.
