A fuel injector with an L-out orifice (L-Step nozzle) at its tip for controlling fuel spray pattern has been developed for the DI engine. The inclined fuel spray pattern formed by the L-Step nozzle was highly stable against the tested ambient pressure range, from 0.1∿0.6MPa. Moreover, the obtained fuel droplet mean diameter was also stable against ambient pressure variation, with only 5μm increase when the ambient pressure was changed from 0.1 to 0.6 MPa. It was also found that the fuel spray pattern could be controlled by changing the fuel swirl force.
