Verfahren zur Regeneration eines Partikelfilters

摘要

The particle filter regenerating procedure, in which a main injection of fuel (30) is applied to at least one of the cylinders of the vehicle's i.c. engine, consists of giving a post-injection of fuel (31) in the same cylinder(s), offset by a predetermined angle in relation to the main injection and at a rate below 8 mg/cp. The angle between the end of the main injection and the start of the post injection is between 3 and 10 degrees of crankshaft rotation. The procedure can also include a pre-injection of fuel (29) into at least one cylinder.
