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.
