Abstract
LE MOTEUR COMPORTE UNE CHAMBRE D'ALLUMAGE 9 RELIEE PAR UN CANAL 10 A L'INTERIEUR DU CYLINDRE, OU UNE CHAMBRE DE COMBUSTION 4 EN FORME DE REVOLUTION EST PREVUE DANS LA TETE DU PISTON 2. LE JET DE COMBUSTIBLE 17 TRAVERSE LA CHAMBRE 9, LE CANAL 10 S'ECRASE SUR LA PAROI 18 DE LA CHAMBRE 4. SOUS L'EFFET DU COURANT D'AIR APPARAISSANT DANS LA CHAMBRE 9, ET DE LA DISPERSION 20 DU CARBURANT, LE MELANGE S'ALLUME DANS CETTE CHAMBRE 9 ET LA FLAMME PARVIENT, PAR LE CANAL 10 DANS LA CHAMBRE 4 OU S'EFFECTUE LA COMBUSTION SELON LE PROCEDE CONNU D'APPLICATION DU COMBUSTIBLE SUR PAROI. AVANTAGES: CE TYPE DE CHAMBRES EST CONNU POUR LES MOTEURS A ALLUMAGE COMMANDE. ON OBTIENT UNE COMBUSTION COMPLETE AUX DIFFERENTS REGIMES POUR UN MOTEUR A AUTO-ALLUMAGE.
