How long the activated carbon tank. It will fail, there will be any fault
Evaporative emission control system has an active carbon storage tank, fuel vapor from the fuel tank from the "TANK" mark into the carbon canister. Liquid fuel entering the carbon canister is stored in a tank at the bottom of the canister to protect the active carbon carbon from the top of the canister, while the fuel vapor is absorbed by the active carbon. When the engine is at idle speed above the running environment, air enters the canister through the upper air pipe, the fuel vapor was washed out from the air blowing carbon, and mixed into mixed gas is sucked into the intake manifold.
. When the engine is running, the electronic control unit is used to control the on-off of the electromagnetic valve of the active carbon canister, and the fuel oil is sucked into the intake port of the engine by the vacuum degree in the air inlet pipe. The use of fuel vapor control can reduce the amount of hydrocarbons in the atmosphere and fuel saving.
Carbon canister (Valve EGR) is used to recover fuel vapor.Working principle of carbon canisterIn order to reduce the environmental pollution caused by the gasoline vapor in the fuel tank and improve the fuel economy, the modern car controls the fuel evaporation. The fuel vapor in the tank is adsorbed by activated carbon in the canister.
