Abstract

An electronically controlled internal combustion engine system comprises fuel injection nozzles (18, 18') opening into an induction passage (14), an air flow rate sensor (58) disposed in the induction passage, and a fuel flow rate sensor (60) disposed in a fuel passage (22) which is provided with a valve (32) to regulate fuel supply rate. Both flow rate sensors (58, 60) are of a type which produce corona discharges in the fluid flow and detect the movement of ions as an indication of the velocity of the fluid flow. An electronic control circuit (56) controls the fuel supply rate regulation valve (32) in accordance with the outputs of the two flow rate sensors (58, 60) such that the mixing ratio of fuel to air agrees with a target value. The system also has a sensor (62) of air flow to the exhaust gas reactor (36) which air flow is intermittent and passes through reed valve (42). Additionally the quantity of exhaust gas recirculated is sensed at (64) and controlled by servo-valve (48) (see Figure 7). Each cylinder is provided with two sparking plugs (50, 50') to ensure combustion at high levels of exhaust gas recirculation. <IMAGE>
