Application of an Active Control Mount(ACM) for Improved Diesel Engine Vehicle Quietness

This paper presents a new Active Control Engine Mount (ACM) that uses adaptive control to improve the quietness of diesel engine vehicles substantially. The ACM has been constructed by incorporating an electromagnetic actuator and a load sensor in a fluid-filled engine mount. A simplified adaptive filter has been achieved by applying the synchronized filtered - X algorithm, focusing on the periodic components of the vibrations induced by engine revolution. As a result, noise and vibration ascribed to a diesel engine are reduced to a level comparable to that of a gasoline engine vehicle for exceptional interior quietness.
