Abstract
A variable displacement internal combustion engine having an intake manifold for providing ambient air and a boost manifold is provided. Either designated cylinders or selected cylinders may be operated in a non-firing mode wherein air may be compressed in a non-firing cylinder and ported to the boost manifold to provide boosted air pressure to firing cylinders. Each cylinder has an intake valve, an intake/compressed air valve, and an exhaust valve. The intake valves are controlled by electromagnetic actuators. The exhaust valve may be controlled by an electromagnetic valve actuator or a conventional valve actuator, if desired. Intake/compressed air valves of cylinders operating in the non-firing, compressor mode are ported to the boost manifold and selectively timed to provide compressed air to the boosted manifold when additional torque is desired provided that some of the cylinders are operating in the compressor mode.
