Description of Opposed Piston, Opposed Cylinder
(OPOC) s30 Engine

• 13.5 hp at 6,000 rpm
• Liquid cooled (fuel or coolant)
• Supercharged (integral with engine)
• Two stroke Diesel (compression ignition)
• JP-8, Diesel, Jet A. JP-8 Diesel also may be
  the lubricant and coolant
• Power Density 0.9 hp per pound
• Dry Engine weight approximately 15lbs not
  including muffler fuel system
• 85cc displacement per module (each cylinder has
  42.5cc)
• 0.65 lbs/hp-hr Fuel Consumption at 13.5 hp (1.0
  gal/hr)
• Engine speed 1,500 rpm to 6,000 rpm

Fuel Injection System Requirements for the OPOC
s30 Engine

• Requirements
• JP-8 primary fuel, Jet A, Diesel Fuel secondary
• 6000 injections per minute per fuel injector (2
  required per engine)
• Fuel injector electronically controlled via pulse
  width modulation
• Fuel supply pressure to injector 400 bar
  (6,000 psi)
• Fuel flow per injector at 6,000 rpm, full load
  8 mm3/injection
• Fuel injection duration at 6,000 rpm, full load
  -30 degrees of crankshaft rotation or 0.83 msec
• Fuel flow at no-load idle (1500 rpm) - 1.5
  mm3/injection, 250 bar fuel supply pressure and
  0.2 msec
