Abstract

The present invention includes a method and apparatus for controlling the exhaust temperature of an engine is disclosed. The method includes the steps of sensing the exhaust temperature of the engine, determining a desired air pressure in response to the exhaust temperature, and controlling the air flow into the engine in response to the desired air pressure. The apparatus includes an air temperature sensor for sensing an actual exhaust temperature within the exhaust manifold and responsively generating an exhaust temperature signal. The apparatus also includes a controller for receiving the exhaust temperature signal and comparing the exhaust temperature signal to a desired exhaust port temperature, determining a desired air pressure in response to the comparison.
