A DEMONSTRATION OF UNIVERSAL COMBUSTION OPTIMIZATION WITH RATE SHAPING (UCORS)

THE PERFORMANCE ADVANTAGES OF THE SERVOJET HIGH PRESSURE, SHORT DURATION, ELECTRONIC FUEL INJECTOR HAVE BEEN DEMONSTRATED. IT IS KNOWN THAT THE RATE OF FUEL INJECTION, AND THE WAY THAT THE RATE VARIES THROUGHOUT THE COMPLETE INJECTION EVENT, HAS A SIGNIFICANT EFFECT ON ENGINE PERFORMANCE. THE NEWLY DEVELOPED SERVOJET UCORS SYSTEM IS A DEVELOPMENT TOOL THAT CAN CONTINUOUSLY VARY THE RATE SHAPE WHILE THE ENGINE IS RUNNING. THIS OPTIMUM RATE CHARACTERISTIC CAN THEN BE DESIGNED INTO A PRODUCTION SERVEOJET INJECTOR. IT IS PROPOSED THAT THE UCORS SYSTEM BE DEMONSTRATED ON A SINGLE CYLINDER RESEARCH ENGINE TO EVALUATE THE PERFORMANCE CHARCTERISTICS OF VARIOUS RATE SHAPES INCLUDING PILOT AND SPLIT INJECTION.
