LiquidPiston

LiquidPiston, Inc. develops compact, quiet, fuel-efficient, low-vibration, multi-fuel capable combustion engines that are scalable from one horsepower to over 1,000. The company's patented High Efficiency Hybrid Cycle (HEHC), an improved thermodynamic cycle, and engine architecture enable the company to create engines optimized for fuel efficiency. LiquidPiston's engines have only two primary moving parts - a shaft and rotor - resulting in compact size and low-vibration operation. Although they are rotary engines, LiquidPiston's engines are not Wankel engines; they are uniquely configured to adopt the company's patented thermodynamic cycle and its associated efficiency and low-noise benefits.
