Abstract
An engine system and method for operating an internal combustion engine includes a turbocharger that generates a boost to the engine. A coolant temperature of the engine is determined along with other based engine inputs and calculated values. A normal boost based on operating conditions of the engine is determined. A supplemental boost is determined based on the coolant temperature. An offset boost based on the normal boost and the supplemental boost is determined. An air output of the turbocharger is modified based on the offset boost. The supplemental boost increases combustion efficiency, which reduces white smoke exhaust.
