EXHAUST SYSTEM AND METHOD FOR CONTROLLING AN EXHAUST SYSTEM |
摘要 |
In one exemplary embodiment of the invention, a method for controlling an exhaust system includes determining an air to fuel ratio within a combustion chamber of an internal combustion engine, measuring a temperature of an exhaust gas flow from the internal combustion engine into the exhaust system and determining a specific heat for the exhaust gas flow in a first segment of the exhaust system based on the temperature of the exhaust gas flow from the internal combustion engine and the air to fuel ratio, wherein the first segment is upstream of the particulate filter. The method also includes determining a first temperature of the exhaust gas in the first segment based on the specific heat for the exhaust gas flow and selectively controlling a regeneration process for the particulate filter using the determined temperature of the exhaust gas at the selected location.
