METHOD FOR LIMITING THE AIR INTAKE NOISE GENERATED AT THE END OF THE REGENERATION OF THE EXHAUST GAS POST-TREATMENT SYSTEM

摘要

A control method for an internal combustion engine including an exhaust gases post-processing system and a system for recirculating the exhaust gases towards the intake, wherein the engine can be switched from a regeneration operation mode with throttling to a nominal mode without throttling. At the end of the engine operation in the regeneration mode, the engine is temporarily operated in an intermediate mode with partial throttling for limiting the contrast of the intake noise.
