Abstract (en)
[origin: WO8606792A1] When the fuel injection of an engine is controlled by an air flow sensor based on a heat radiation principle, an air fuel ratio sensor (10) capable of detecting the air fuel ratio of rich range from exhaust gas components is provided, and even if abnormal increase in the output signal of the air flow sensor occurs due to the blow-off of intake air at full load time, a feedback control is executed so that the air fuel ratio does not become rich higher than the predetermined value by the signal from the air fuel ratio sensor.
