Abstract
The disclosure describes an internal combustion engine and a method for operating an internal combustion engine, in which an electronic controller is programmed to determine whether the internal combustion engine is operating within a cylinder cutout enabling region and, when the engine operates in the cylinder cutout enabling region, to cutout one or more of the engine cylinders by causing the cutout cylinder's fuel injector to cease injecting fuel into cutout cylinder, and to also cause the still-active engine cylinders to operate with an additional amount of fuel such that a steady state engine torque output remains unchanged before and after the second cylinder is cutout.
