    Abstract: A mechanism for varying crankshaft timing on a belt/chain driven, dual crankshaft opposed-piston engine includes sprockets on corresponding ends of the two crankshafts, connected by a belt or chain which is tensioned by two or more tensioners. By changing the position of the tensioners the length of the two spans of the belt/chain are varied and thus the phase between the crankshafts is varied.

    Abstract: A variable camshaft timing system for an internal combustion engine varies the relative angular position between the intake camshaft and the exhaust camshaft by controlling the path of the timing belt (16). First and second idler arms (18, 20), each having an idler wheel (22, 24) connected thereto, are independently pivoted around a common pivot point (42) by means of a pair of positioning cams (34, 36) operatively connected to an electric stepping motor (28). The motor is controlled from an electronic control unit (41) which receives signals indicating the engine operating parameters and through a look-up table steps the positioning cams which in turn pivots the idler arms to rotate the intake camshaft relative to the exhaust camshaft thereby changing the intake valve timing.
