PURPOSE: A vapor gas control system is provided to improve continued ratio by increasing an idle stop period by controlling vapor gas sampled in a canister. CONSTITUTION: A vapor gas control system comprises a canister(140), a throttle valve(75), paths(15,20), a purge control valve(150) and a controller(180). The vapor gas is sampled in the canister. The throttle valve is installed in a suction passage in which the air is inhaled. The path is connected to the throttle valve backend of the suction passage from the canister. The purge control valve is installed at the path. The controller stops the engine in an idle state. The controller closes the throttle valve, if a canister load value reaches a first set value or greater. The controller opens the purge control valve and inflows the vapor gas to the air intake passage. |
