The system includes an ejector having an intake pipe for intake of intake gas, an ejection pipe for ejection of the intake gas and vapor gas, and a suction pipe for suctioning the vapor gas. A first purge line is connected between the suction pipe of the ejector and a vapor gas outlet port of a canister and a second purge line is connected between the ejection pipe of the ejector and a gas suction pipe at a front end of a throttle valve. An intake gas branch line is connected between the intake pipe of the ejector and a predetermined position of an intake gas line.
