Abstract
A control system and method for a multi-combustion chamber internal combustion engine. Balance running between the combustion chambers is achieved by varying the engine operating parameters or the parameters of a load driven by the engine. In addition, knocking can be detected and corrected by also sensing the rate of acceleration of the engine output shaft at certain crank angles.
