Abstract
To improve ignition timing precision without being subjected to a harmful influence of gear backlash produced when the distributor unit is directly driven by a camshaft and further to mount the distributor unit on the front cover at any desired inclination angle for reduction of total engine height, the distributor driving apparatus for an DOHC engine, in particular comprises two camshaft sprockets fixed to two camshafts; an idler sprocket rotatably supported between the two camshafts and the crankshaft; a first chain reeved around the crankshaft and the idler sprocket; a second chain reeved around the idler sprocket and the two camshaft sprockets; and a distributor driving gear fixed to the idler sprocket. Therefore, when the crankshaft is rotated, the idler sprocket is driven by the crankshaft via the first chain and therefore the distributor unit is directly driven by the distributor driving gear. On the other hand, the camshaft sprockets are driven by the idler sprocket via the second chain.
