Abstract: A method for operating an engine of a machine is provided. The method determines a first engine operating speed of the engine from an engine speed detection module using a controller and then determines a current throttle position of the machine using a throttle detection module using the controller. The method further includes calculating a throttle-to-minimum engine operating speed map based on a correlation of the current throttle position and the first engine operating speed using the controller. The throttle-to-minimum engine operating speed map is lesser than the first engine operating speed. The method selectively regulates a current operating speed of the engine based on the throttle-to-minimum engine operating speed map using the controller, if the trigger event persists. The method selectively regulates the current operating speed of the engine based on the first engine operating speed using the controller, if the trigger event does not persist.
