Abstract

LA PRESSION D'INJECTION EST ABAISSEE DE 50 ET LA DUREE DE L'INJECTION EST ALLONGEE, COMMENCANT A 54 DE ROTATION DU VILEBREQUIN AVANT LE POINT MORT HAUT DU PISTON. ON A UN MEILLEUR MELANGE ET UNE BONNE COMBUSTION. LA CONSOMMATION DE COMBUSTIBLE EST MOINDRE, LA TEMPERATURE DES GAZ D'ECHAPPEMENT ET L'EMISSION DE SUIE SONT REDUITES.
