Mechanism For Varying Crankshaft Timing On A Belt/Chain Driven, Dual Crankshaft Opposed-Piston Engine

摘要

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.
