PURPOSE:To simplify structure, reduce cost, and promote utility by adopting a control metering system of injection discharge as well as a system to inject fuel continuously to a collected part of suction pipes for simplifying functions. CONSTITUTION:In an arithmetic circuit 36, the optimum air-fuel ratios are stored to correspond to the operating state of an engine on the basis of data determined experimentally or by design. When the circuit is operated, the above written air- fuel ratio is looked for on the basis of input values from element sensors 37 and 38, and the obtained air-fuel ratio is multiplied by a suction air discharge, the input value from the sensor 37, to compute a required value of fuel discharge for transmitting to a signal generating circuit 34. Then, in the signal generating circuit 34, an operation area and a duty stage are looked for and obtained, and an operation signal is output to a metering valve 11. By this operation, pressurized fuel is injected from injectors 9 and 29. |
