PURPOSE: To prevent emission of fuel evaporative gas from a fuel tank in oil feeding. CONSTITUTION: When an oil feeding switch 53 is operated prior to oil feeding, a solenoid valve 42 is opened under control of an electronic control unit 21 complying with a switch output, and at the same time, a compressor 23 is operated, so that fuel evaporative gas inside a fuel tank is fed into a reservoir 22 via pipes 31, 32. During operation of an engine, the control unit 21 complies with the output from a pressure switch 52 indicating a reservoir internal pressure and opens solenoid valves 43, 44 when the reservoir internal pressure exceeds the preset pressure so as to let the fuel evaporative gas inside the reservoir 22 into an intake manifold 2 via a pipe 34. |
