An engine control system and method of controlling an engine system are provided. The engine control system includes at least one sensor module configured to generate an exhaust condition signal based on a determined condition in an exhaust component and a cylinder bank control module communicatively coupled to the at least one sensor module. The cylinder bank control module is configured to cause transmission of a first bank control signal to cause a first bank of cylinders of an engine to deactivate at least in part in response to a determination based on the exhaust condition signal that a hydrocarbon mass quantity is above a pre-determined hydrocarbon mass quantity threshold.

Cylinder deactivation for catalyst drying

Disclosed herein is a system for managing combustion in an internal combustion engine includes a detection module that determines a combustion condition of the internal combustion engine. The combustion condition includes one of a first combustion condition or second combustion engine. The system also includes a fuel table module that receives the combustion condition and selects an engine operating request based on data in a first fuel table when the combustion condition is the first combustion condition, and data in a second fuel table when the combustion condition is the second combustion condition. The system additionally includes an engine control module that receives the engine operating request and generates engine operating commands based on the engine operating request.

System and method for dual fuel engines

A method for controlling fueling of an internal combustion engine is provided. The engine may include an intake manifold, one or more exhaust manifolds and a turbocharger coupled between the intake and exhaust manifolds. The method may comprise estimating an operating condition of the turbocharger, determining a maximum value of an operating parameter as a function of the estimated operating condition of the turbocharger, measuring a value of the operating parameter, determining an error value as a function of the maximum value of the first operating parameter and the measured value of the operating parameter, and limiting fuel supplied to the engine based on the error value.

System for limiting engine output power by controlling fueling

System for controlling engine fueling to limit engine output power

An algorithm for use in an engine control module to control peak cylinder pressure in a diesel engine under high altitude operating conditions, including an initiation and entering routine configured to determine whether conditions are met for advancing a start of injection time used by the engine control module to cause an injection of fuel into a cylinder of the engine, an increment routine that is executed by the engine control module when the initiation and entering routine determines that the conditions are met to advance the start of injection time using a first increment when the first increment is less than or equal to an increment step and less than or equal to a second increment, and advance the start of injection time using the second increment when the first increment is greater than one of the increment step and the second increment, and an exiting routine that is executed by the engine control module when the initiation and entering routine determines that the conditions are not met to decrement the start of injection time when the first increment is less than or equal to a decrement step.
