Systems and methods to control cold transient response via air assist

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...

Beschreibung
Zusammenfassung:	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.
