The Pulstar product offers very high power spark discharge, on the order of 1MW, to accelerate combustion pressures enabling forced semi-homogeneous combustion for all conditions. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber.

Isuzu D201 35 hp diesel engine (left) and the LiquidPiston 40 hp X2 Prototype (right). Expected realized brake efficiency for the X2 is 58% (peak) and 50% at partial load; power density is targeted to be around 2 hp/lb. Power modulation by cycle skipping increases efficiency and recaptures heat. Click to enlarge.

The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes. Compound HPE is divided into a compressor cylinder and a power cylinder, combined with a compressed air storage tank. A paper on the use of JCCI is published in the ACS journal Energy & Fuels.

The prototype is of the naturally-aspirated Split Cycle gasoline engine, and is intended to be a proof of the basic technology of the split cycle with firing after Top Dead Center (one of the key attributes of the engine and cycle). Completion of the turbocharged Scuderi Engine and the Scuderi Air-Hybrid are expected in 2010.
