EFFERVESCENT ATOMIZATION OF GASOLINE CONTAINING DISSOLVED CO₂

An experimental study of the steady-state atomization process of gasoline containing dissolved CO₂, is presented. A fuel injection system has been designed to produce a spray having a lower Sauter mean diameter (SMD) than that obtained typically with a direct fuel injection system for the same injection pressure. The downstream part of the injector consists of an inlet orifice, an expansion chamber, a swirl duct, and a discharge orifice. When …
