What is the electromagnetic cutting of 2006 7-generation Accord accelerator carbon canister?

The function of carbon canister solenoid valve is only to control the oil and gas in carbon canister. After the engine is turned off, gasoline vapor and fresh air are mixed in the fuel tank and stored in the activated carbon fuel tank. When the engine is started, the solenoid valve installed between the activated carbon canister and the intake manifold is opened, and the gasoline vapor in the activated carbon canister is brought into the cylinder by clean air to participate in combustion under the vacuum degree of the intake pipe. This not only reduces emissions, but also reduces fuel consumption. The carbon canister is actually a part of the gasoline evaporation control system (EVAP), which is introduced to prevent fuel vapor from escaping into the atmosphere after the engine stops running. Since 1995, it has been stipulated in China that all new cars must have this system.
