Abstract

For actuating the inlet and outlet valves, two parallel overhead camshafts respectively are assigned to the two cylinder banks of a multi-cylinder V-engine and are driven by an intermediate timing gear by means of chain drives. The intermediate timing gear is driven by the crankshaft by means of gear wheels. The camshaft drive is arranged between the end bearing of the crankshaft and the flywheel.
