Sturman injectors are capable of nozzle pressures from 300 to 3000 bar (4351 to 43,511 psi) and injection volumes from 1 mm3 to 2100 mm3/stroke.

The U.S. Army Research, Development, and Engineering Command (RDECOM) has selected Sturman Industries to execute the objective of SBIR (Small Business Innovation Research) Topic A11-064 “Advanced Rotary Diesel Engine Fuel Injection System for Unmanned and Manned Ground Vehicles.” The stated objective is “to examine, develop, and demonstrate the use of an advanced high-pressure injection system in a heavy fuel (DF-2 and JP-8 compatibility) rotary diesel engine for unmanned and manned ground vehicle applications.” The fuel-injection system presents a significant challenge, according to Sturman, due to difficult spray targeting length and time scales associated with rotary diesel combustion systems. Using digital valve technology, Sturman will utilize features such as flight weight design, unique injection spray, custom packaging, and integrated electronics. Multi-fuel capability is a benefit of Sturman injectors via local intensification design and materials selection, allowing use of fuels such as Jet-A, Jet-A1, JP-8, JP-5, DF-2, heavy fuel oil, and biodiesel. Sturman, in collaboration with manufacturing partners, is pursuing low- to medium-volume production opportunities of niche valve and injection applications such as for UAVs, large marine, industrial, and locomotive engines. Unit volumes for these applications range from 5000 to 50,000 units per year. Production is expected to begin as early as 2013.
