Abstract
Passage of an engine piston through reference positions while traveling toward and away from a dead center position is sensed to produce pulses that define an engine displacement, the midpoint of which corresponds to the passage of the piston through the dead center position. Expressions of motion for the full displacement and one of the half displacements are simultaneously solved to determine the time at which the piston passed through the dead center position.
