PURPOSE:To simplify suction system path structure by sharing a bypath for performing idling control with an air bleed path for fuel injection valve. CONSTITUTION:Air to be fed through an air-cleaner 3 is fed together with fuel to engine body 1 through a suction path 2. Said suction path 2 is provided with a throttle valve 4 interlocked with the accelerator pedal. Fuethermore a bypath 5 for bypassing said throttle valve 4 to communicate between upper and down stream of throttle valve 4 in the suction path 2 is provided. The downstream end of said bypath 5 is opened at the position near to the nozzle section 6a of fuel injection valve 6 facing against the suction path 2. Consequently suction system path structure can be simplified. |
