Abstract (en)

[origin: WO0159269A2] The invention concerns a method for injecting fuel into at least one of the cylinders of a combustion engine (12), in particular a diesel engine, for regenerating a nitrogen oxide trap (16), which consists in injecting a main amount of fuel depending on the engine (12) operating point. The invention is characterised in that it consists in increasing the main amount during a phase regenerating the nitrogen oxide trap (16).
