ABSTRACT:
A multiple-displacement engine which can be operated either in a full-displacement operation in which all the cylinders are operative or a two-cylinder operation in which only two of the cylinders are operative is provided with a balancer control device. The balancer control device comprises a balancer which is driven at the same rpm as the engine output shaft during the two-cylinder operation and reduces the primary vibration generating moment imparted to the engine structure due to explosion, an engine load sensor for detecting engine load, an engine rpm sensor for detecting the engine speed and a balancer changing mechanism which changes the vibration generating moment of the balancer according to the operating condition of the engine so that the vibration generating moment of the balancer approximates the primary component of the vibration generating moment of the engine structure due to explosion thereby suppressing the primary vibration generating moment of the engine structure over the entire operating range during two-cylinder operation.
