Fuel injection and mixing systems and methods of using the same

摘要

A fuel injection and mixing system is provided. The system includes an injector body having a fuel inlet and a fuel outlet, and defines a fuel flow path between the inlet and outlet. The fuel flow path may include a generally helical flow passage having an inlet end portion disposed proximate the fuel inlet of the injector body. The flow path also may include an expansion chamber downstream from and in fluid communication with the helical flow passage, as well as a fuel delivery device in fluid communication with the expansion chamber for delivering fuel. Heating means is also provided in thermal communication with the injector body. The heating means may be adapted and configured for maintaining the injector body at a predetermined temperature to heat fuel traversing the flow path. The fuel injection and mixing system may also comprise an injection housing with a mixing chamber attached thereto, the mixing chamber including a mixer and a peripheral wall having an axially converging and diverging undulating surface. A method of preheating and delivering fuel is also provided.
