Gas-assisted fluid atomization injector

摘要

To provide a liquid injector atomizer for direct injection into a cylinder of an internal combustion engine.SOLUTION: The liquid injector atomizer comprises a supply of pressurized liquid, a supply of pressurized gas, a body, and a nozzle with two or more orifices each for the liquid and the gas. Each orifice directs a jet of metered pressurized liquid or pressurized gas out of the injector body. At least two of the liquid jets are aimed at one or more collision points, where at least two gas jet streams collide at the same collision point or another collision point, thereby creating a finely atomized liquid.SELECTED DRAWING: Figure 1
