SYSTEMS AND METHODS FOR SELECTIVELY ACTIVATING ENGINE CYLINDERS TO MAINTAIN MINIMUM CYLINDER PRESSURE

A system for controlling operations of an engine comprises a plurality of cylinders and a controller operatively coupled to each of the plurality of cylinders. The controller is configured to determine an operating condition of the engine, and in response to determining that the operating condition...

Zusammenfassung:	A system for controlling operations of an engine comprises a plurality of cylinders and a controller operatively coupled to each of the plurality of cylinders. The controller is configured to determine an operating condition of the engine, and in response to determining that the operating condition is suitable for activating less then all cylinders of the plurality of cylinders during a cycle of the engine, determine a first firing pattern, and a second firing pattern different from the first firing pattern for activating the plurality of cylinders of the engine. The controller is configured to activate a first set of cylinders of the plurality of cylinders based on the first firing pattern, and subsequent to activating the first set of cylinders, activate a second set of cylinders of the plurality of cylinders different from the first set of cylinders based on the second firing pattern.
