Ultra High Pressure Jet Propellant-8 (JP-8) Fuel Injection

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, especially JP-8. Hydraulically intensified, ultra high pressure fuel injectors, together with advanced closed-loop engine controls, provide the performance and flexibility necessary to reach the next level in diesel engine performance. In Phase I of this project, a hydraulically intensified fuel system capable of meeting the desired performance objectives was identified and analyzed. The objectives of Phase II of this project are to finalize the design, manufacture and bench test a set of hydraulically intensified, ultra high pressure fuel injectors that will meet the military"s engine performance and injector durability objectives and be ready for installation into a military relevant engine platform for dynamometer testing.
