LiquidPiston

Connecticut-based engine developer making a radically new take on the rotary engine. LiquidPiston's X-Engine is delivering extraordinary efficiency and power density, and the company has been contracted to develop it as a super-lightweight portable generator for the US Army.

  • A fresh and extremely powerful take on the rotary engine. Connecticut company LiquidPiston is developing a portable generator for the US Army using its X-Engine, which promises as much power as the Army's current gen-set at one-fifth the size.
  • Imagine an engine that's 30 percent smaller than a traditional piston design of like output, and that runs smoothly, with less noise and vibration. Plus, it burns several types of fuel. That's the LiquidPiston X rotary engine, which was recently demonstrated powering a go-kart.
  • Back in 2012, Gizmag looked at LiquidPiston’s X2 rotary engine and now the company is back with the 70 cc X Mini engine, which LiquidPiston’s President and Co-Founder, Dr Alexander Shkolnik unveiled on Wednesday at the SAE International/JSAE 2014 Small Engine Technology Conference in Pisa, Italy.
