Abstract

L’invention concerne un ensemble comprenant un moteur (1) thermique relié à une ligne (2) d’admission d’air et une ligne (3) d’échappement, une ligne de dérivation d’air s’étendant entre un piquage (2a) sur la ligne (2) d’admission et un piquage (3a) sur la ligne (3) d’échappement, cette ligne de dérivation d’air comprenant une pompe à air (4a) destinée à tirer l’air de la ligne (2) d’admission d’air et l’insuffler dans la ligne (3) d’échappement, caractérisé en ce que cet ensemble comprend encore -des moyens de contrôle du débit de gaz disposés sur la ligne (2) d’admission d’air ou la ligne (3) d’échappement entre les deux piquages de la ligne de dérivation d’air, un module de contrôle (5) configuré de sorte à activer la pompe à air (4a) et fermer les moyens de contrôle du débit de gaz pendant une période précédant un démarrage du moteur (1) thermique. Figure 1The invention relates to an assembly comprising a thermal engine (1) connected to an air intake line (2) and an exhaust line (3), an air bypass line extending between a connection ( 2a) on the intake line (2) and a tap (3a) on the exhaust line (3), this air bypass line comprising an air pump (4a) intended to draw air from the air intake line (2) and blow it into the exhaust line (3), characterized in that this assembly further comprises - means for controlling the gas flow arranged on the line (2) of air intake or the exhaust line (3) between the two taps of the air bypass line, a control module (5) configured so as to activate the air pump (4a) and close the means of control of the gas flow during a period preceding starting of the thermal engine (1).
