METHOD AND APPARATUS FOR DETERMINING TEMPERATURE IN A GAS FEEDSTREAM |
摘要 |
An internal combustion engine includes an exhaust gas feedstream flowing past a gas sensing device disposed therein. The gas sensor includes an integrated electrical heating element which provides a resistance indicative of its temperature. An unknown input observer is used to determine the exhaust gas feedstream temperature based on the heating element temperature.
