Patent ID: 7104224

Claim:
A fuel system, comprising: an injector configured to receive fuel and to transmit fuel in droplet form; a conduit having inner walls defining a reaction region, downstream of said injector, said reaction region to receive fuel from the injector; and a cylindrical in shape reaction rod, positioned completely in the reaction region, the reaction rod having a convex end, in the reaction region and facing to receive the fuel from the injector, the reaction rod further having a concave end at a second end opposite the convex end, and said reaction rod having a cylindrical body formed by walls that extend between said concave end and said convex end, where said fuel from said injector is directed to flow between said walls of said reaction rod and said inner walls of said conduit in a direction from the convex end to the concave end, and wherein said reaction rod reduces an inner surface area of said conduit for said fuel flow relative to an area of said conduit which does not include said reaction rod therein.
