Abstract
A camshaft driving arrangement for a DOHC engine comprises two pairs of sprockets, each pair being mounted to the adjacent pair of camshafts, and two idler gears rotatably mounted to the cylinder banks, respectively. A timing chain drivingly interconnects the crankshaft and the two idler gears. On the other hand, two camshaft driving chains each interconnect one of the two idler gears and the adjacent two cam sprockets. A front cover is so constructed and arranged as to conceal the two idler gears and the timing chain.
