ABSTRACT:
A power unit mount includes a housing in which first and second electrode bodies are suspended and which is filled with a fluid which exhibits a change in viscosity when a voltage is applied thereacross. The control of the voltage application is determined by a control circuit which is operatively connected to a plurality of sensors which include an engine speed sensor, a road wheel speed sensor, a relative displacement sensor and an absolute displacement sensor. A variant includes a solenoid powered vibration generator which can be energized under predetermined conditions in a manner to improve vibration attenuation.
