| Summary: | A gas vapor control system that controls gas vapor that is generated in a fuel tank may include a canister in which the gas vapor is captured, a throttle valve that is mounted in an intake passage through which air passes, a gas vapor passage connecting the fuel tank to a portion of the intake passage formed before the throttle valve, wherein the canister is positioned at the gas vapor passage, a purge control valve that is mounted on the gas vapor passage, and a control portion that stops an engine in an idle stop condition, and that closes the throttle valve and opens the purge control valve to flow the gas vapor into the intake passage when a canister load value (CL) is higher than a predetermined value. |
