Abstract
A camshaft driving arrangement for a DOHC engine comprises two pairs of cam sprockets, each pair being mounted to each of the camshafts at one end thereof, and two idler gears, each being rotatably mounted to one of the cylinder heads. A first camshaft driving chain drivingly interconnects one of the idler gears and the adjacent pair of the cam sprockets. On the other hand, a second camshaft driving chain drivingly interconnects the other of the idler gears and the other pair of the cam sprockets. The second camshaft driving chains have different running planes which are axially spaced along the axis of the crankshaft.
