Abstract
A control system and method for increasing engine temperature for an engine having a variable nozzle turbo (VNT) is provided. An offset idle module generates an offset idle signal. A normal boost module calculates a normal boost. A supplemental boost module calculates a supplemental boost. An offset boost module generates an offset boost signal for the VNT based on the normal boost and the supplemental boost. A control module adjusts engine idle and VNT boost based on the offset idle signal and the offset boost signal.
