Abstract
A system for indicating the timing of an engine control event relative to the top dead center position of an internal combustion engine. A sensor responsive to piston movement develops pulses of equal angular width before and after the top dead center position of a selected piston, and the time relation of the sensor pulses with respect to the initiation of an engine control event is used to determine the timing of the engine control event with respect to the piston top dead center position. The timing so determined is compensated for engine acceleration by taking into account the difference in duration of the two sensor pulses.
