Abstract
A four-stroke cycle, multi-cylinder reciprocating internal combustion engine has a camshaft phaser or phasers for adjusting the timing of the intake and exhaust camshafts with respect to the rotational position of the crankshaft so that some of the cylinders of the engine may be deactivated such that the intake and exhaust valves for each deactivated cylinder open and close at points which are approximately symmetrical about a rotational position of the crankshaft at which the direction of motion of the pistons change.
