The camshaft chain drive of variable compression ratio reciprocating piston engine having a crankshaft mounted in an eccentric carrier and having a variable camshaft to crankshaft sprocket center distance includes a chain guide mounted to the eccentric carrier. According to the present invention, pivotal motion of the eccentric for varying the compression ratio also moves the chain guide and in turn the chain pathway for maintaining a functional chain tension at all compression ratio settings. The present invention may be used for chain or belt drives, and may be used for driving the camshaft (s), engine accessories, and/or other power take-off shafts.
