Isuzu D201 35 hp diesel engine (left) and the LiquidPiston 40 hp X2 Prototype (right). Other features of the X2 include: Quiet operation: engine lacks poppet valves and over-expansion minimizes exhaust noise. Click to enlarge. LiquidPiston, Inc. Power modulation by cycle skipping increases efficiency and recaptures heat.

Alternative Fuel Technology, LLC has been awarded a Phase 1 SBIR contract (W56HZV-10-C-0200) from the US Army to concept design and demonstrate an ultra-high pressure, intensified fuel injection system for use with jet propellant (JP-8) fuel. With most fuel injection systems, JP-8 fuel causes wear and premature failure.

Several other combustion modes are derived from the HCCI combustion concept: low temperature combustion (LTC), partially premixed charge compression ignition (PCCI), and reactivity-controlled compression ignition (RCCI) combustion modes. In the experiments, the researchers used a 425 cm 3 single-cylinder engine based on a GM/Isuzu 1.7
