In the process of the correction, the deviation of the air-fuel ratio from a reference air-fuel ratio in acceleration or deceleration of the engine is detected, and the correction value of the fuel injection amount correction in the transient state of the engine in accordance with the detected air-fuel ratio deviation is determined. In the correction of amount of fuel injection in the transient state of the engine, the correction value is decided on the basis of a factor for deciding the correction value and the blunted value of the factor for deciding the correction value.

摘要： A gas flow measuring apparatus includes first and second temperature dependent resistors located in a gas tube respectively downstream and upstream of an electric heater which is also located in the gas tube. The first and second temperature dependent resistors are connected to form a bridge circuit together with first and second reference resistors. Between a pair of diagonal junctions of the bridge circuit, a potential difference is produced depending on the flow rate of the gas and the power supplied to the electric heater, and a measuring circuit controls the power supplied to the electric heater so that the potential difference is maintained at a predetermined value irrespective of a change in flow rate of the gas. The measuring circuit includes a chopper circuit to convert the potential difference into a square wave having a peak-to-peak value substantially equal to the potential difference and having a center reference level of the square wave corresponding to a voltage level determined by a reference voltage generator and an adder circuit. The square wave from the chopper circuit is then amplified and half rectified and applied to a sample-hold circuit to produce a voltage signal representative of the potential difference. A differential amplifier having two inputs of the voltage signal from the sample-hold circuit and a predetermined voltage produces an output signal which is used to control the power supplied to the electric heater. A current flowing into the electric heater is used to determine the flow rate of the gas.
