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. An air-standard analysis predicts an ideal thermodynamic efficiency of 74% at an 18:1 compression ratio.
