Provided is an injector () having a plurality of injector modules () that include a spray cup having a chamber and a plurality of radial air passages for directing air radially into the chamber, and a pressure swirl atomizer attached to the spray cup and having a fluid passage for directing fluid axially into chamber and an air passage for directing air axially into the chamber. By providing radial and axial air flow and axial fuel flow into the chamber, the fuel may be mixed to prevent local hot spots that lead to high NOx emissions, and a stable flame may be maintained without autoignition and flashback. The axial air flow also prevents recirculation zones from forming at a base of the spray cup, provides improved atomization and enhanced combustion.

Direct injection multipoint nozzle

A nozzle assembly comprises a first-fuel-inlet tube, a second-fuel-inlet tube, and a plate stack. The nozzle-plate stack () defines a central circuit, corner air circuits, a first fuel circuit and a second fuel circuit. The fuel circuits include a swirl chamber in which the fuel is swirled prior to being merged with the central circuit. The corner air circuits merge with the central circuit downstream of the fuel circuits' merge and provide an additional swirling component to further shape the fuel-air stream prior to ignition.
