Abstract: 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.

Abstract: Systems and methods for bypassing a compromised engine cylinder via cylinder deactivation are described according to various embodiments herein. A system includes an engine coupled to a controller. The controller includes at least one processor and at least one memory coupled to the at least one processor. The at least one memory stores instructions that, when executed by the at least one processor, cause the controller to: determine that one or more cylinders of a plurality of cylinders of the engine is compromised based on data regarding operation of the engine; and cause the engine to operate in the modified engine operating mode whereby operation of the one or more cylinders that are compromised is modified.

Abstract: A system includes a controller having at least one processing circuit including at least one memory coupled to at least one processor. The controller is configured to: receive data regarding operation of an engine indicating that one or more cylinders of a plurality of cylinders of the engine is compromised; cause the engine to operate in a modified engine operating mode whereby operation of the one or more cylinders that is compromised is modified; cause the engine to operate in a non-modified engine operating mode whereby operation of the one or more cylinders that is compromised is not modified responsive to receiving information regarding a predetermined condition despite the data regarding operation of the engine indicating that the one or more cylinders of the plurality of cylinders of the engine is compromised.

Abstract: A system and method of controlling operation of an internal combustion engine are provided. The method includes performing a cylinder deactivation operation while running the engine, selecting at least one of the plurality of temperature maintenance actions to increase an exhaust temperature, and performing at least one of the plurality of temperature maintenance actions effective to increase the exhaust temperature. The plurality of temperature maintenance actions may include one or more of a charge air cooler bypass operation, an EGR cooler bypass operation, an aftertreatment system heater operation, a turbocharger bypass operation, a turbocharger geometry adjustment operation, an intake air throttle adjustment operation, and a delayed injection timing operation, or combinations thereof.
