Abstract

PURPOSE: To adequately keep the quantity of fuel fed over the whole operation range of an engine, by arranging this fuel feeder by a fixed Venturi system carbureter and a fuel injection valve installed to a downstream of a throttle valve of the carbureter.
CONSTITUTION: A fuel injection valve 17 is disposed to a downstream of a throttle valve 16 and an upper stream of a riser portion 10 in a carbureter 5 in an intake pipe 4 provided with an air cleaner 2 and an air flow-meter 3, and the valve opening time of the injection valve 17 is controlled by means of a control unit 26. The control unit 26 is operated and arranged in such a manner that the unit 26 is subject to output from the air flow-meter 3, an oxygen sensor 27 and other measuring means, the fuel injection valve 17 is worked and fuel is fed only from said valve 17 in a low sucked air quantity range and the functioning of said injection valve 17 is stopped and fuel is supplied only by means of the carbureter 5 in a high sucked air quantity range.
