ABSTRACT:
In an engine load detecting apparatus and ignition control apparatus for an internal combustion engine, in accordance with the pulse signals from a reference position detector for detecting a plurality of reference positions of a crankshaft of the engine an interval average rotation speed for each of the intervals between the generation of the pulse signals is calculated and the interval average rotation speeds are utilized in such a manner that a speed pulsation value is obtained from the difference between the maximum and minimum ones thereof and an engine speed is obtained from the average value thereof thereby determining an engine load or ignition timing in accordance with the speed pulsation value and the engine speed.
