摘要： A fuel control system for an internal combustion engine capable of correcting an inlet air flow rate, used for the computation of a fuel injection, in consideration of a blow-back flow rate. The inlet air flow rate is detected by a hot-wire type sensor and sampled by a control unit. The control unit determines whether or not the sampled inlet air flow rate has reversed twice its gradient from the negative one to the positive one between predetermined crank angles of the engine and computes the blow-back flow rate subtracted from the inlet air flow rate.

The system is equipped with a Karman vortex air-flow sensor, at least one injector for feeding a fuel into an internal combustion engine, a controller for controlling the quantity of the fuel, which is to be injected, on the basis of intake air flow rate information from the air-flow sensor, and at least one operation parameter sensor. The controller also includes at least one additional control unit which serves to correct the quantity of the fuel, which is to be fed into the engine, in accordance with at least one operation parameter from the operation parameter sensor and frequency information outputted from the air-flow sensor. The quantity of the fuel, which has been determined based on an output from the air-flow sensor, is corrected by the controller in accordance with changes in kinematic viscosity of the atmospheric air.

摘要： An air-fuel ratio controller which detects oxygen content of the engine exhaust gases, compares the detected value with an objective oxygen content corresponding to an objective air-fuel ratio and integrates the deviation therebetween, smoothes the integrated values to absorb errors in control caused by variations in an injector or the like, and controls the air-fuel ratio in accordance with such integrated and smoothed values. The air-fuel ratio controller always controls the air-fuel ratio properly by stopping the smoothing of the integrated values when, for example, the detected oxygen content is disordered, and the detected values do not vary remarkably for more than a predetermined period.
