The Army is in need of a heavy fuel rotary engine with rated power between 10 and 80 HP that is compatible with both JP-8 and DF-23 and has a high power to weight ratio. Since it is difficult to adapt light-duty, automotive diesel piston engines for these applications, considerable development has been pursued on heavy fuel, rotary diesel engines. Currently many of the engines rely on existing automotive style fuel injection hardware that has not been designed for use in these high speed rotary applications. This project will develop a flexible, high pressure fuel injection system to meet the desired requirements. The work will focus on improving the injection spray characteristics and designing a fuel system to meet the size and weight constraints of these applications.
