Abstract
A method is present for estimating engine load factor. Temperature data is obtained from a temperature sensor in a location with respect to an exhaust system for an engine. A rate of temperature change is estimated using the temperature data. A steady state temperature at a selected time is calculated for the location using the temperature data and the rate of temperature change. The engine load factor at the selected time is estimated from the steady state temperature.
