Abstract

Agencement de fixation de circuit d’admission d’air de moteur thermique à injection indirecte de carburant comprenant une culasse (15) dans laquelle sont creusés des canaux d’admission (17) qui débouchent d’un côté dans un enfoncement (20) de la paroi d’admission (12) de la culasse et du côté opposé dans une chambre à combustion (16), ladite culasse comprenant au moins un canal d’injection par cylindre apte à loger un injecteur de carburant et débouchant de façon oblique dans un canal d’admission (17), Ledit circuit d’admission comportant un échangeur de chaleur (11) fixé à la paroi d’admission de la culasse de façon oblique grâce à une bride de fixation (50), Caractérisé en ce que l’enfoncement (20) de la culasse est divisé en cavités d’admission (19) par au-moins une paroi de séparation (18), chacune desdites cavités communiquant avec une unique chambre à combustion (16) et en ce que l’échangeur (11) est divisé en compartiments longitudinaux (81), chacun desdits compartiments est connecté avec une unique cavité d’admission (19) de la culasse.
