Abstract
A first temperature sensor senses the temperature of intake air supplied to an internal combustion engine before the intake air is mixed with fuel supplied thereto. A second temperature sensor senses the temperature of the mixture of the intake air and fuel within the intake air passage. A control unit controls the fuel injection quantity in accordance with the difference between the sensed temperatures, thereby causing the actual air-fuel ratio to coincide with a desired air-fuel ratio. The desired air-fuel ratio is adjusted in accordance with the throttling effect of a throttle valve in the intake air passage and with engine speed.
