Solenoid Valve - Yamaha F50F Service Manual

Solenoid valve

Just after the engine is stopped, the cooling water supply is also stopped and the heat is conducted
to the vapor separator from the engine, causing birth of many fuel vapor gases.
The vapor gases are fed into the intake silencer to reburn them.
However, many vapor gases are sucked into the combustion chambers, causing a rich air and fuel
mixture, which is difficult to restart the engine.
So the solenoid valve has been used for better restarting engine while the engine is warm.
The solenoid valve stops the vapor gases not to return into the intake silencer.
