An internal combustion engine includes a driving shaft, a pair of camshafts for driving engine valves, a transmission connecting the driving shaft to a first of said camshafts and a transmission connecting the first camshaft to the second camshaft. The transmission connecting the two camshafts to each other includes a pair of articulated parallelogram mechanisms each having two crank members rotatable with end portions of the camshafts and connected to each by means of a connecting rod. The crank members are made up of circular discs eccentrically mounted on the camshafts and rotatably received in circular openings formed at the ends of the respective connecting rod. The two crank members rotatable with the same camshaft are spaced from each other by a determined angle.

A method is disclosed for positioning the crankshaft of an engine. The method comprises the steps of providing a first hole in the flywheel, providing a hole in a stationary part of the engine to line up accurately with the hole in the flywheel once during each crankshaft revolution, manually cranking the engine until the holes in the flywheel and the engine are aligned, and inserting a pin into the aligned holes to lock the crankshaft in a predetermined angular position.
