Abstract
CETTE CULASSE EN ALUMINIUM COMPORTE UNE CHAMBRE DE REFROIDISSEMENT 9 ET UN CERTAIN NOMBRE DE CAVITES QUI CONSTITUENT POUR CHACUN DES CYLINDRES4 DU MOTEUR, UNE CHAMBRE DE PRECOMBUSTION 5 EN COMMUNICATION A SA PARTIE SUPERIEURE AVEC UN SIEGE6 D'INJECTEUR DE COMBUSTIBLE. CHACUNE DES CHAMBRES DE PRECOMBUSTION 5 AINSI QUE LE SIEGE6 D'INJECTEUR QUI LUI EST ASSOCIEE SONT DELIMITES PAR UNE PAROI8 DONT LA SURFACE EXTERIEURE EST SITUEE DANS LA CHAMBRE DE REFROIDISSEMENT9. CETTE CHAMBRE DE REFROIDISSEMENT 9 EST SEPAREE PAR UNE CLOISON DE SEPARATION 20 EN UNE PARTIE INFERIEURE ADJACENTE AUX CHAMBRES DE PRECOMBUSTION 5 ET UNE PARTIE SUPERIEURE ADJACENTE AUX SIEGES D'INJECTEUR. DES OUVERTURES 21 SONT MENAGEES DANS LA CLOISON20 A COTE DES CHAMBRES DE PRECOMBUSTION DE SORTE QUE LE FLUIDE DE REFROIDISSEMENT TRAVERSANT LES OUVERTURES21 EST OBLIGE DE S'ECOULER SUR LES PAROIS CYLINDRIQUES8 DES CHAMBRES DE PRECOMBUSTION.
