PROBLEM TO BE SOLVED: To enable to obtain the good restartability without making the fuel concentration downstream of a throttle valve too high even when oil-tight leakage occurs in an injector. SOLUTION: When an injection switch 22 is turned OFF from ON, it is judged as an engine stop to open the throttle valve 7. As a result, even when oil-tight leakage occurs in the injector 12, vaporized gas of the fuel produced by oil-tight leakage can be diffused through the throttle valve 7 to the upstream side, so that the fuel concentration downstream of the throttle valve 7 is not made too high, and the good restartability can be obtained.
