Abstract: A control system of an engine is provided. The control system includes an inlet sensor configured to generate a signal indicative of an engine inlet air temperature and an intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature. The control system includes a control module communicably coupled to the inlet sensor and the intake manifold sensor. The control module is configured to determine the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine a pre-stored de-rate modifier corresponding to an engine speed. The control module is configured to determine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.

Abstract: A method for controlling an internal combustion engine includes receiving a request for a desired output from the internal combustion engine, receiving sensor information indicative of at least an engine speed or a pressure of gas provided to the internal combustion engine, and setting a changeable limit associated with a supply of air and fuel to the internal combustion engine. The method also includes, based at least in part on the received sensor information, changing the changeable limit to define a changed limit and reducing an output of the internal combustion engine based on the changed limit.

Abstract: A control system and method to control cold transient response of an engine. The control system can provide compressed air from a compressed air source to a turbocharger to boost speed of a turbine of the turbocharger, based on determined desired operating characteristics associated with upstream or downstream operation of the engine relative to the turbocharger. The control system can receive data corresponding to actual operating characteristics associated with the upstream or downstream operation of the engine relative to the turbocharger, compare the desired operating characteristics with the data corresponding to actual operating characteristics, and control the air assist from the compressed air source based on the comparison.
