ABSTRACT:
A method of and an apparatus for regenerating a diesel filter (1) mounted in the exhaust pipe (3) of a diesel engine (2) wherein for initiating regeneration, the exhaust flow is throttled in the exhaust pipe (3) and/or in an exhaust feedback passage (7) by means of a control unit (10) responsive to setpoint exhaust temperatures measured upstream and downstream of the diesel filter (1) in the exhaust pipe (3), and that the air ratio is set to a value between 1.2 and 1.3 to inhibit regeneration.
