Abstract

The invention relates to a control method for an internal combustion engine (1) including an inlet circuit (2) comprising a main inlet duct (5) and a secondary inlet duct (5a), and an exhaust circuit (3) that comprises an exhaust-gas post-treatment system (19), the engine being capable of operation in a regeneration phase for regenerating the post-treatment system (19), in which the inlet circuit is shut with an inlet flap (14) and a normal phase without shutting with said flap (14), characterised in that the air passage section in the secondary inlet duct (5a) is adapted by a blocking means (20) for reducing the air-inlet noise contrast between the regeneration phases and the normal phases.
