Abstract: A method of operating an engine includes determining an intake air temperature and an engine speed. The method includes selectively initiating one of a first operating mode, a second operating mode and a third operating mode based on at least the intake air temperature and the engine speed. The first operating mode includes increasing the engine speed progressively by an incremental speed value. The second operating mode includes deactivating at least one Exhaust Gas Recirculation (EGR) cylinder of the engine. The third operating mode includes shutting down the engine.

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.
