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

The Army uses intensified fuel injection systems on a number of their diesel powered vehicles. These systems are currently limited to injection pressures of about 20,000 psi. In an effort to increase thermal efficiiency (fuel economy), raise power output and operate on a variety of heavy hydrocarbon fuels, the army desires to develop an ultra-high pressure (>40,000 psi)intensified fuel injection system. In Phase 1, we are developing and will demonstrate a single injector system that will meet the Army's criteria. To reach the pressure goals we are using a COTS injector but are developing a higher pressure common rail pump and a common rail that can withstand the ultra-high pressure. In Phase 2, we will develop a full 6 cylinder system, including electronics, that will"bolt onto"an Army COTS diesel engine.
