Development of Electronic Controlled Fuel Injector and Pump Suitable for 5-20 Horsepower Diesel Cycle Engines

Phase II will enable KBEI to demonstrate a complete high pressure Micro Injection System on a Navy UAV engine in a laboratory environment. While the Micro Injectors and Micro Pump have been successfully proven at lower pressures, this STTR program has facilitated research and development of a higher pressure injection system designed for use with heavy fuels. At the conclusion of the Phase II STTR, the demonstration will include field capable hardware and controls operating a high BMEP-style engine. A TRL 7 for the complete fuel delivery system is expected. The Micro Injection system will feature a high pressure Micro Injector (target to 30,000 psi), a high pressure Micro Pump, and a small engine controller. The effort will include design and development, modeling and analysis utiling in-house Computtaional Fluid Dynamic analysis and Finite Element Analysis, as well as fabrication and demonstration of the hardware through bench testing and laboratory testing. In parallel to the demonstration, KBEI will execute a transition plan to provide field ready (TRL 8-9) system capable in field use. Strategic partners, engine suppliers and UAV integrators will be a key to a successful transition of the Micro Injection technology into the field.
