ABSTRACT:
A four-stroke cycle, multi-cylinder reciprocating internal combustion engine (10) has a camshaft phaser (34) for adjusting the rotational position of the intake and exhaust camshafts (25, 26) with respect to the rotational position of the crankshaft (12) so that some of the cylinders (8) of the engine (10) may be deactivated. A common intake plenum (38) provides intake air to each of the cylinders (8) during normal engine operation, while an exhaust system (40) receives exhaust gasses from both the deactivatable cylinders (8a) as well as the other cylinders (8b). The cam phaser (34) adjusts the camshaft positions during cylinder deactivation operation such that the deactivated cylinders (8a) pump exhaust gas through the deactivated cylinders (8a) into the common plenum (38), which is employed by the still active cylinders (8b) as EGR gas.
