Abstract

In a V-type engine with two bore-offset banks opposed to one another at a predetermined angle, an accessory mechanism is provided between the two banks. A drive belt for the accessory mechanism is disposed on the side of one of the banks which is recessed inwardly due to the bore offset. In another embodiment, the accessory mechanism is a supercharger driven by a balancing shaft which, in turn, is driven by the crank shaft. In yet another embodiment, the V-type engine has a separate timing belt for each bank, that is, a first timing belt for the bank which is recessed inward because of the bore offset, and a second timing belt for the bank which juts out because of the bore offset. A drive belt is provided for driving the supercharger. The belts are arranged in the following order from the inside outward: the second timing belt, the first timing belt and the accessory belt.
