The high-speed/high-resolution imaging system was used to evaluate two mid-pressure (15 MPa) fuel injector nozzles in ambient air and in a motored single-cylinder test engine. The nozzles are designed for use in the EPA/NVFEL program to develop clean and efficient engines that use alternative fuels. The report is part of an ongoing investigation to analyze the transient spray characteristics for direct-injection type fuel injectors. The experimental results compare a single-hole and a three-hole nozzle and conclude that both of these injector nozzles yield similar spray patterns and atomization and could be particularly useful for combustion systems where injection into a piston bowl is required.
