Abstract (en)
[origin: WO2005090759A1] An exhaust filter regeneration regime is described in which a filter (20) is regenerated by triggering an exothermic reaction in the filter (20) to burn off particulate load. In order to attain the appropriate regeneration temperatures fuel is injected in the exhaust stream and oxidises upon contact with a catalytic converter (18). A control regime comprises metering fuel injection dependent upon exhaust stream temperature to provide a flexible control regime independent of engine duty cycle.
