Abstract

PURPOSE:To improve air fuel ratio control accuracy and adjustability by controlling the throttling of a fuel passage in a fuel injection system in accordance with suction air pressure and fuel injection pressure. CONSTITUTION:A bellows-type first pressure member 10 is provided which makes reciprocating shift at atmospheric pressure ratio while introducing the lower course side pressure of a throttle 7 provided on a suction pipe 2. Further, a second pressure receiving member 19 is provided which makes reciprocating shift at atmospheric pressure ratio while introducing fuel pressure from the lower course side than the fuel adjusting valve 15 of a fuel supply passage 3 extending to a fuel injection nozzle 4. The members 10 and 19 are interconnected by an operation lever 13. The control of fuel supply rate is made through that of the fuel adjusting valve 15 in accordance with the reation of working force therebetween. Thereby a system can be obtained which has a simple structure, a high control accuracy and a maintenance advantage.
