Abstract
The relative power contribution of each cylinder in an internal combustion (IC) engine which is connected through a common drive shaft to an engine load and which is running at a selected speed, is provided as the relative magnitudes of each cylinder's contribution to the fluctuations in a sub-cyclic net torque signal provided as the difference torque value between an instantaneous sub-cyclic engine torque signal and an instantaneous sub-cyclic load torque signal.
