Abstract
A method comprises determining a temperature of a particulate matter (PM) filter in communication with an exhaust gas from an engine; and reducing a power output of the engine when the PM filter is not being regenerated and the temperature exceeds a first predetermined temperature. A control module comprises a PM filter temperature determination module that determines the temperature of a PM filter in communication with an exhaust gas from an engine; and a reduced engine power module in communication with the PM filter temperature determination module that reduces the power output of the engine when the PM filter is not being regenerated and the temperature exceeds a first predetermined temperature.
