Filed: 1981-08-12
Abstract: PURPOSE:To improve the measuring accuracy of the titled device by providing a solenoid valve which passes the fuel for a predetermined time in synchronism with the output of a vortex flow meter having a frequency output in proportion to the suction air quantity, and a second solenoid valve which limits the quantity of the fuel passing through the solenoid valve. CONSTITUTION:Air to be fed to an engine 1 is sucked up through a suction pipe 2. The air flow quantity is measured by a vortex flow meter 4, and supplied to an electronic controller 24 as a frequency output. On the other hand, the fuel is fed with pressure from a tank 8 to a fuel measuring device 13 via a pipe 12 by means of a pump 9, and injected through a fuel injecting pipe 5 into the suction pipe 2. A first solenoid valve 15, a second solenoid valve 19, and a third solenoid valve 21 are subjected to the control of the controller 24.
