Project 2-Development of an Ultra-High Pressure Jet Propellant-8 (JP-8) Fuel Injection System for the Navistar MAXX Force DT Engine. The second Army program began in 2010 with a Phase 1 project to demonstrate an intensified fuel injector that can achieve 40,000 psi injection pressure using JP-8 fuel. We were able to successfully reach the goal on a single cylinder bench and were subsequently awarded a Phase 1 Option and then a full Phase 2 program. The total value of these projects is $846,000. Our Phase 2 program is based on using an advanced (new) version of our DME fuel pump, a unique new common rail and a modified Navistar hydraulically intensified injector.
The pump, although similar in concept to our proven DME pump, has a 25% larger displacement, and can run at up to 4000 rpm. It is physically smaller, lower cost and more robust than our previous pumps. It is capable of pumping lube oil (for the Army project), hydraulic fluid, diesel fuel, JP-8 and DME at pressures above 500 Bar (7500- 8000 psi). It is an inlet throttled design that provides infinitely variable flow output without mechanical complexity. Therefore, it should be attractive to both the fuel injection and industrial hydraulics market.

This Phase 2 project was started in July 2011 and is ahead of plan. We will have hardware running in several months. This is an extremely challenging program because of the very high pressures that must be achieved. To our knowledge, there are no commercial fuel injection systems that can achieve 40,000 psi. This program will be completed in August 2014. When successful, we believe that there will be a U.S. and international market for this product using both DME and diesel fuel. We are already starting to look at packaging a special version of the intensified injector on popular truck, construction and agricultural engines.
