Abstract
An exhaust control system includes a temperature sensor, a temperature estimation module, and an exhaust condition adjustment module. The temperature sensor measures an outlet temperature of an exhaust gas downstream from an emission reduction device. The temperature estimation module estimates a highest temperature of the emission reduction device. The exhaust condition adjustment module controls operation of the exhaust control system based on the highest temperature of the emission reduction device.
