Method and apparatus for preventing overheating of diesel particulate filter
Disclosed is a method and apparatus for operating an internal combustion engine. The method comprises monitoring the temperature T of a Diesel Particulate Filter (DPF) and monitoring a parameter indicative of engine load, such as engine speed ES or engine torque ET. The detected engine load is used...

| description | Disclosed is a method and apparatus for operating an internal combustion engine. The method comprises monitoring the temperature T of a Diesel Particulate Filter (DPF) and monitoring a parameter indicative of engine load, such as engine speed ES or engine torque ET. The detected engine load is used to determine a threshold DPF temperature T_th. A diagnoses test determines that the DPF is overheated if the measured DPF temperature is higher than the threshold DPF temperature. A recovery strategy such as limiting the engine output may be implemented if it is determined that the filter is too hot and is overheating. The method also provides a way of determining the rate of change of the temperature of the filter. |
