Sturman ADVANCED Alternative Fuel Injection Program completed
FOR the Department of Defense
SBIR Phase II Ultra-High Pressure JP-8 Fuel Injection Program
Demonstrates Enabling Alternative Fuel Technology
In August of 2013 Sturman Industries completed testing to demonstrate the capability of a fuel system that is JP-8 and alternative fuel compatible. The goal was to accomplish this objective while maintaining wide spread commercialization potential for the resultant product.
The specific design targets for the fuel system included:
· Proven durability operating on JP-8/JET-A fuel
· Ultra-high injection pressures
· Small pilot and post injections
· Flexible electronic control of multiple injections
Nine injectors were fabricated, all of which were bench tested, two were also used for 10 million cycle extreme duty durability testing.
The design targets were achieved via:
· Two injectors were run to 10 million cycles with JP-8 analog test fluid with 0 failures
o One injector was run at 3300 bar peak injection pressure and 2800 bar average injection pressure, the other at 2800 bar peak injection pressure. Over 10 million cycles less than 1% injection quantity variation was measured.
· 1-2 mm3 pilot and post quantity control was demonstrated throughout the range of injection pressure
o Pilot PW maps with an average shot-to-shot variability of 0.14 mm3 were generated
· Multiple injection maps with both pre and post injection events were generated
Fuel System Leads to Fuel Flexibility and Improved Emissions, Efficiency and Power Density
Future military diesel engines will require fuel system improvements to meet their desired performance targets including increased power density, increased fuel economy, reduced heat rejection and the ability to operate on different heavy hydrocarbon fuels. With the flexibility of closed-loop engine controls, electronic control of the fuel system and the development of a fuel-flexible capable injection system, the possibility exists to target on the fly the desired engine performance using any fuel. Sturman Industries technologies and the Digital Injector in particular are proving ready for that future to be now.
