PROCEDE DE PILOTAGE D'UN MOTEUR THERMIQUE EN FONCTION DE CONDITIONS THERMODYNAMIQUES DANS LES LIGNES D'ADMISSION ET D'ECHAPPEMENT

摘要

The invention relates mainly to a method for operating a combustion engine (10) comprising: ㆍ – a step of operating the combustion engine (10) in a nominal mode whereby an overlap between the intake valves (19) and the exhaust valves (20) is forbidden or limited through control of the intake phaser (211) and/or of the exhaust phaser (212), ㆍ – a step of detecting conditions of activation of a dynamic mode which are associated with the extent to which an accelerator is depressed and with a combustion engine (10) torque condition, ㆍ – and when the thermodynamic conditions of the combustion engine (10) have stabilized, said method involves a step of activating said dynamic mode whereby an overlap between the intake valves (19) and of the exhaust valves (20) is permitted through control of the intake phaser (211) and/or of the exhaust phaser (212).
