    • A fuel feed control system and method for an internal combustion engine is provided with a device for setting the quantity of fuel and a fuel injector for feeding fuel in accordance with the fuel quantity set by the fuel quantity setting device. The fuel quantity setting device is provided with a device for estimating the quantity of air to be inducted on the basis of the result of detection of the quantity of inducted air at an inducted air quantity detection time, inducted air quantity information detected before the inducted air quantity detection time and predicted information. The inducted air quantity estimation device is provided with a device for changing the predicted information so that, when a transient operation state of the engine is detected by a transient operation state detector, the estimated quantity of inducted air and a real quantity of inducted air become closer to each other. The control system permits setting of an accurate injection quantity of fuel by precisely measuring a quantity of inducted air even when the state of operation of the engine is in a transition period.

    • A method and apparatus for controlling operating conditions of an internal combustion engine based upon sensed operating parameters of the engine expressed in the form of pulse signals, wherein the frequency of the pulses is representative of the sensed parameter. The pulse intervals of the sensed operating parameter signals are measured to the fractional level before being stored and employed by a CPU to calculate data applied to control predetermined operating conditions of the engine, such as the fuel flow rate and the ignition timing. The inventive method and apparatus attain greater operating stability for steady-state operations and excellent response under transient conditions of the engine.
