    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.

A controller controls the supply of fuel to fuel injectors for the engine based on the output of the calculator. The load detector includes a frequency divider which performs frequency division of the output from the air flow sensor when the load exceeds a prescribed level.

    摘要： A system and a method for controlling fuel supply to an internal combustion engine are disclosed in which excessive supply of fuel to the engine is effectively prevented in a most reliable manner particularly at the time of engine deceleration. To this end, a reduction in the amount of intake air sucked into an engine per intake stroke is sensed, and the amount of fuel supplied to the engine is reduced when there is a reduction in the intake air amount sucked into engine per intake stroke. The amount of reduction in the fuel supply is changed in accordance with at least one of the number of revolutions per minute of the engine and the amount of intake air sucked into the engine per intake stroke.
