蒸気のパージ制御装置。 A purge pipe extending from a fuel vapor collection mechanism that temporarily collects fuel evaporated in the fuel tank opens into an intake pipe in which first and second throttle valves are provided that open and close independently of each other. Due to the negative pressure generated in the intake pipe according to the opening degree of the first throttle valve,
In a fuel vapor purge control device in which fuel vapor and air in the coal canister are guided into the intake pipe through the purge pipe, the flow rate of the fuel vapor and air flowing through the purge pipe is controlled. A fuel vapor purge control device comprising a valve mechanism, the valve mechanism restricting the flow rate when substantially negative pressure is generated in the intake pipe by the second throttle valve.
