Abstract

PURPOSE: To increase fuel supply without increasing an orifice inner diameter in size, by increasing fuel supply in qnantity through a fuel supply passage as well as a fuel supply bypass passage at the time of starting or warming up operation.
CONSTITUTION: An air control valve 15 in a bypass passage 5 attached to an intake passage 2 and a needle 16 provided in a passage 10 associated with a fuel tank 13 are controlled relatively to each other by a solenoid device 17 put under control of CPU8. That is, it is constituted in such a way that fuel supply is increased as a flow rate of air is decreased. At the time of starting or warming up operation, a solenoid valve 52 is opened, so that fuel is fed into the intake passage 2 via a passage 53 and the bypass passage 51.
