How to connect the solenoid valve of intake branch pipe of Pentium B70 vacuum regulator with the solenoid valve of carbon canister?

The carbon canister solenoid valve of the intake branch of Pentium B70 vacuum regulator is generally installed around the intake straight pipe, with one plug and two wires. When the pressure is higher than a certain value, the pressure limiting valve is opened to discharge gasoline vapor into the atmosphere. Later, in order to save fuel and protect the environment, people set up a carbon canister, which was filled with activated carbon with strong adsorption.

Matters needing attention in installation of carbon canister solenoid valve tube

Excess fuel vapor in the fuel tank is no longer discharged into the atmosphere, but introduced into the activated carbon tank through a pipe. Activated carbon absorbs fuel vapor. When the car starts, the solenoid valve of the activated carbon tank is opened in time to pour the absorbed fuel vapor back into the intake manifold, which is fuel-efficient and environmentally friendly.

Locate the canister solenoid valve next to the throttle, and then remove the canister solenoid valve with a vice. Unscrew the screw at the top of the carbon canister solenoid valve with needle-nosed pliers, and the carbon canister solenoid valve can be opened. Please pay attention to a small spring after opening. Don't lose it. Removing the valve core will be accompanied by a lot of carbon particles. These carbon particles are the objects we want to remove. Clean the valve body with alcohol and reinstall it.
