Abstract
A system is disclosed for controlling fuel injectors in an internal combustion engine having a plurality of individual engine cylinders with associated pistons. The system includes at least one electronic engine control module configured to control the fuel injectors and having a memory with predetermined injector firing patterns stored therein. The firing patterns specify the fuel injectors to be fired and the fuel injectors to be skipped, in an engine cycle under conditions of reduced power demand. For each engine cycle in a succession of cycles under the reduced power demand condition, the engine control module determines the number of fuel injectors to be fired based upon the reduced power demand data, selects from the stored predetermined firing patterns a firing pattern specifying the injectors to be fired and the injectors to be skipped, and orders the specified fuel injectors to be fired sequentially in accordance with the selected predetermined firing pattern.
