| 摘要 |
The present invention relates to a fuel supply apparatus in which the controllability of the air flow-rate is simplified and can promote the reduction of harmful substances discharged from the engine (1). An air control valve (32) is provided downstream of an electronic throttle valve (10) in an intake pipe (9). Air having passed through the electronic throttle valve (10) is caused to flow from a main passage of an intake pipe (9) to a bypass (39, 40) as the occasion demands by using the air control valve (32), and vaporized fuel is supplied from a combustion stabilizing device (13, 23) to the air allowed to flow to the bypass (39, 40). The quantity of air caused to flow to the bypass (39, 40) is controlled by the electronic throttle valve (10) in the state where the control valve (32) is closed.
