ABSTRACT:
A system for synchronously activating cylinders of a multicylinder, fuel injected, four stroke cycle internal combustion engine, includes a valve operator for deactivating intake and exhaust valves associated with the cylinders and a controller for selecting a cylinder to be deactivated, as well as a timing mechanism for determining when the selected cylinder is operating during intake events. The controllers directs the valve operator to begin deactivating the valves of a selected cylinder during a predetermined intake event, with the valve operator completing the deactivation by a time not later than the beginning of the next exhaust event.
