Abstract

La présente invention concerne un système servant à introduire le carburant dans la chambre de combustion (13) d'un moteur à combustion interne (10) comportant au moins un piston (14) qui accomplit des va-et-vient dans un cylindre (12), avec une culasse (16) qui ferme le haut du cylindre et forme une chambre de combustion entre le piston et elle-même. Au moins une soupape d'admission (22) et une soupape d'échappement (24) sont prévues dans la culasse (16). Un ou plusieurs injecteurs de carburant (34) traversent la paroi latérale de chacun des cylindres (12) du moteur pour injecter du carburant pendant la course d'admission du piston, alors que le sommet de ce dernier se trouve au-dessous du point d'injection. L'injecteur de carburant (34) peut être tout injecteur approprié, généralement du type à basse pression. Il est orienté de manière à pulvériser des gouttelettes de carburant (26) vers la culasse et/ou la soupape d'échappement fermée, afin d'accélérer l'évaporation des gouttelettes et de refroidir la soupape d'échappement. Les moteurs utilisant ce système acceptent aussi plus facilement le carburant à faible indice d'octane et leurs caractéristiques d'émission de produits nocifs sont améliorées.
