Engines designed for applications where less is more

Less weight, space, vibration, noise, fuel consumption… More power. Building on over 15 years of R&D, LiquidPiston provides a power solution that can scale to address the needs of the $400B internal combustion engine market and is a key enabler for emerging mobility technologies including electric cars, urban aircraft, and drones.

The company is focusing on military and aerospace markets, whose propulsion and power generation segments represent large application opportunities for LiquidPiston. The company also plans to enter industrial and commercial, marine, UAV, urban mobility, and automotive markets.

Technology

LiquidPiston’s rotary engines are the first disruption to engine technology in over a century. These 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. LiquidPiston’s X Engine improves virtually all parameters – efficiency, weight, size, vibration, and noise.
