Abstract

A method and system of deactivating exhaust valves, intake valves and cylinders associated with the intake and exhaust valves in a multi-cylinder engine to provide a seamless transition from an engine status where all the cylinders and their associated valves are active to an engine status where one or more cylinders and their associated valves are inactive and vice versa. The method includes the steps of: increasing fuel delivery to a first set of cylinders of the multi-cylinder engine and decreasing fuel delivery to a second set of cylinders of the engine 18 until the volume of fuel delivery to the second set of cylinders is substantially zero; deactivating the intake and exhaust valves associated with the second set of cylinders 22 as the volume of fuel delivered to the second set of cylinders approaches zero; and adjusting fuel delivery to the first set of cylinders such that a substantially constant level of output torque from the engine is maintained 26. A method of reactivating the cylinders is also claimed.
