| Abstract: | This report presents test results obtained during an investigation of the performance of a single-cylinder, high-speed, compression-ignitioin test engine when using multiple-orifice fuel-injection valve nozzles in which the number and the direction of the orifices were varied independently. The orifice sizes generally conformed to the principle that the orifice area should be proportional to the volume of air served by the orifice. The test results indicate that it is unnecessary to follow the proportional principle to extremes and that complication of nozzle design dose not give a commensurate increase in performance. The optimum angle between orifice axes was judged to be 25 degrees for the conditions in this quiescent combustion chamber, but this value is not critical. |
