Abstract

L'invention concerne un ensemble moteur (1) à combustion interne comprenant - un répartiteur d'admission (2) comprenant • plusieurs conduits d'admission (21) ; • un plenum tubulaire (3) desservant de l'air comprimé dans tous les conduits d'admission (21) via une entrée principale (30) ; - un réservoir (5) contenant un agent anti-cliquetis pulvérisé. Selon l'invention, le plenum tubulaire (3) comprend un col du Venturi disposé en amont de l'entrée principale. Le réservoir (5) d'agent anti-cliquetis pulvérisé débouche dans le plenum tubulaire (3) au niveau du col du Venturi. L'ensemble comprend en outre un système de circulation forcée faisant déplacer de l'agent anti-cliquetis pulvérisé vers le plenum tubulaire (3).The invention relates to an internal combustion engine assembly (1) comprising - an intake distributor (2) comprising • several intake ducts (21); • a tubular plenum (3) serving compressed air in all the intake ducts (21) via a main inlet (30); - a reservoir (5) containing a sprayed anti-knock agent. According to the invention, the tubular plenum (3) comprises a neck of the Venturi arranged upstream of the main inlet. The reservoir (5) of sprayed anti-knock agent opens into the tubular plenum (3) at the neck of the Venturi. The assembly further includes a forced circulation system moving sprayed anti-knock agent to the tubular plenum (3).
