| 发明名称 | Dual action fuel injection nozzle | ||
| 摘要 | The disclosure provides a fuel injection nozzle. The fuel injection nozzle includes a nozzle body, with the nozzle body defining a central bore. A fuel atomizer is disposed in the central bore. The fuel atomizer defines a spill-return bore and a swirl chamber. The swirl chamber is in fluid communication with the central bore. The spill-return bore includes a return swirler approximate the swirl chamber. An air supply pump is coupled to the fuel atomizer and is in fluid communication with the spill-return bore. The air supply pump is configured to selectively inject air into the swirl chamber through the spill-return bore. | ||
