Method of supercharging an engine

A variable displacement internal combustion engine having a plurality of internal combustion cylinders that have a firing mode and a compressor mode comprising:

• an intake manifold for providing air to a first set of intake valves with one valve being provided for each of the cylinders;
• a boost manifold for receiving compressed air from cylinders operating in the compressor mode and providing compressed air to cylinders operating in the firing mode;
• each cylinder has an intake valve controlled by a first electromagnetic actuator, an intake/compressed air valve controlled by a second electromagnetic actuator, and at least one exhaust valve controlled by a third valve actuator;
• and
• wherein the intake/compressed air valves of cylinders operating in the compressor mode are ported to the boost manifold and are selectively timed to provide compressed air to the boosted manifold when additional torque is desired when operating some of the cylinders in the compressor mode, the engine being a four-cycle engine having an intake stroke, a compression stroke, a combustion stroke and an exhaust stroke that is operated in a variable displacement mode wherein the intake valves open during the intake stroke and the combustion stroke, the intake/compressed air valves open during the compression stroke and the exhaust valve opens during the exhaust stroke.
