Abstract:
1. An engine vibration isolation system comprising: an active vibration isolation support system for supporting, on a vehicle body, an engine that can switch among an all-cylinder running, a first modified running and a second modified running, wherein said first modified running and said second modified running differ from one another in the number of cylinders that are cut off; and a control portion for controlling an actuator of the active vibration isolation support system according to a vibrational state of the engine so as to suppress transmission of vibration from the engine to the vehicle body, wherein, when a ratio of an order of vibration of the first modified running to an order of vibration of the second modified running is not an integer, the control portion interposes the all-cylinder running, in which all the cylinders are operated, in a transitional period between the first modified running and the second modified running.
