    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.

    摘要: An ignition timing control apparatus for an internal combustion engine has an air flow sensor for sensing the air flow rate into the air intake pipe of the engine and producing an electrical output signal in the form of pulses having a frequency which is proportional to the air flow rate, and a crank angle sensor for producing an electrical output pulse each time the crankshaft of the engine is at a prescribed crank angle. A pulse counter counts the number of output pulses from the air flow sensor between consecutive output pulses of the crank angle sensor. A controller controls the current to an ignition coil based on the engine rotational speed and on either the output of the pulse counter, or on the output of a calculating mechanism which calculates the amount of intake air into the cylinders of the engine between consecutive output pulses of the crank angle sensor based on the output of the pulse counter.
