Abstract

L'invention concerne un carburateur comprenant un corps (22) pourvu d'un étranglement (24) s'étendant depuis une entrée (26) jusqu'à une sortie (28) et un injecteur de carburant (32) positionné dans cet étranglement et comportant un orifice d'amont, sensiblement orienté vers l'amont, et un orifice d'aval, sensiblement orienté vers l'aval. Une surface utile de l'orifice d'amont est inférieure à une surface utile de l'orifice d'aval. Si plusieurs orifices sont prévus de chaque côté, une surface combinée de tous les orifices d'amont est inférieure à une surface utile combinée de tous les orifices d'aval. L'orifice d'amont est positionné plus près du corps du carburateur que les orifices d'aval. L'orifice d'aval comprend plusieurs orifices d'aval dont la position moyenne est centrée par rapport à l'étranglement.
