Abstract (en)
[origin: EP0417383A2] In a process for cleaning a soot filter (4) in the exhaust pipe (2) of a diesel engine (3), the flow of exhaust gas (5) is directed through a burner (1). When the load on the soot filter (4) reaches a certain level, the burner (1) is ignited by injection of fuel into the burner (1). The soot that has collected in the soot filter (4) is burned by the hot combustion gas. This regeneration of the soot filter (4) is initiated, however, only when the instantaneous operating point of the engine (3) lies within a predetermined ignition characteristic field (Z). The fuel injection stops as soon as the motor reaches an operating point which lies outside a predetermined combustion characteristic field (B) that is greater than the ignition characteristic field (Z).
