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.

Abstract: An exhaust gas recirculation (EGR) system is provided. The EGR system includes an engine having an intake manifold. The intake manifold is adapted to receive intake air from an aftercooler. The EGR system also includes an exhaust manifold. The exhaust manifold is adapted to receive exhaust gas from a plurality of cylinders of the engine. The EGR system further includes an EGR line. The EGR line is fluidly coupled between the intake manifold and the exhaust manifold. The EGR system includes an EGR valve disposed in the EGR line. The EGR system also includes a pressure line. The pressure line is coupled between the intake manifold and the EGR valve. The EGR valve is movable to an open position from a closed position, based on an intake pressure communicated to the EGR valve via the pressure line.
