Patent ID: 8156730

Claim:
An apparatus for controlling the temperature of the exhaust of an internal combustion engine for a regeneration event on a particulate matter filter, comprising: a regeneration module configured to determine a desired particulate matter filter inlet exhaust gas temperature for a regeneration event; a turbocharger thermal management module configured to determine a variable geometry turbine (VGT) device position strategy; a fuel injection thermal management module configured to determine a fuel injection strategy; an air intake throttle thermal management module configured to determine an intake throttle position strategy; and an exhaust throttle thermal management module configured to determine an exhaust throttle valve position strategy; wherein the VGT device position strategy, the post-injection fuel injection strategy, the intake throttle position strategy, and the exhaust throttle valve position strategy are configured to cooperatively achieve the desired particulate matter filter inlet exhaust gas temperature; wherein the internal combustion engine is operable in a low speed operating range, a high speed operating range, and a transition operating range between the low and high speed operating ranges; wherein the exhaust throttle valve position strategy comprises closing the exhaust throttle valve when operating in the low speed operating range, and opening the exhaust throttle valve when operating in the high speed operating range; and wherein the regeneration module, turbocharger thermal management module, fuel injection thermal management module, air intake module, and exhaust throttle thermal management module each comprises one or more of logic hardware and executable code, the executable code stored on one or more non-transitory machine-readable storage media.
