ABSTRACT:
A vehicle and drive unit therefor including a transversely disposed engine located in an engine compartment. The cylinders are inclined to the rear from a vertical plane at an acute angle and the engine crankshaft drives an accessory output shaft that rotates in a plane disposed in an acute angle to the vertical and forwardly of the cylinder axis and at an acute angle to the cylinder axis. A two-stage camshaft drive arrangement is provided for driving a pair of overhead mounted camshafts and the two stages of this drive include flexible transmitters that are disposed on opposite sides of one of the cylinders so as to provide a compact assembly. An intermediate shaft is driven by this drive arrangement and is supported at one side of the cylinder head. One of the drives is disposed between a pair of ports in this side of the cylinder head and this drive is accessible through a removable cover plate positioned between the ports.
