  • CYLINDER CUTOUT STRATEGY FOR OPERATION OF ENGINE
    Publication number: 20160252033
    Abstract: The disclosure provides a method to operate an engine including a first set of cylinders and a second set of cylinders with the help of an engine control module (ECM). The ECM determines a current engine speed, a current engine load, and a current degree of rotation. If the current engine load is below a threshold load that corresponds to the current engine speed, the ECM selects a cylinder cutout strategy. The ECM initiates the cylinder cutout strategy wherein the fuel supply is cutout alternatively between the first set of cylinders and the second set of cylinders at a predetermined degree of rotation. The fuel injection is modified by a predetermined amount to a set of non-cutout cylinders. The ECM deactivates the cylinder cutout strategy when the current engine load exceeds the threshold load that corresponds to the current engine speed.
