PROBLEM TO BE SOLVED: To prevent an aggravation of the state of vibration in a transitional period between the first cylinder-resting operation and the second cylinder-resting operation, the numbers of resting cylinders of which are different from each other. SOLUTION: In case of changing-over between the L3 cylinder resting operation in which cylinders on one bank of a V-type six-cylinder engine are halted and the V4 cylinder resting operation in which one cylinder on each bank of the engine is halted, the V6 all-cylinder operation in which all the cylinders are operated is interposed between the L3 cylinder resting operation and the V4 cylinder resting operation. As a result, a transitional period exists between the L3 cylinder resting operation and the V6 all-cylinder operation and between the V6 all-cylinder operation and the V4 cylinder resting operation, and a transitional period does not exist between the L3 cylinder resting operation and the V4 cylinder resting operation. Therefore, it is possible to simplify control of an active type vibrationproof supporting device in the transitional period and to prevent the aggravation of the state of vibration in the transit period.
