Abstract

The present invention is capable of ensuring that sufficient evaporated fuel is introduced into a combustion chamber. A connection passage 163 is provided for introducing evaporated fuel from a canister 161 to an air intake passage 110. A solenoid valve 170 is provided in the connection passage 163. The solenoid valve 170 is arranged at a position such that the capacity between a downstream air intake passage 110x and the valve, in a connection path 163a inside the connection passage 163, is less than half of the exhaust volume of an engine 130. Inside a downstream air intake passage section 110d: a negative pressure having a large difference from atmospheric pressure and a negative pressure having little difference from atmospheric pressure are generated within four strokes; and a negative pressure fluctuation is generated whereby a negative pressure having a large difference from atmospheric pressure and a negative pressure having little difference from atmospheric pressure are repeated every four strokes. The solenoid valve 170 is controlled so as to be linked to the negative pressure fluctuation every four strokes.
