LiquidPiston is currently developing and testing the X Mini, a power-dense, low-vibration, quiet, 70 cubic centimeter gasoline powered rotary four-stroke engine prototype. The compact engine (4-pound core) has only two primary moving parts.

The 40S is a small and compact engine that delivers a market-leading power to weight ratio. By integrating a modern rotary engine with our revolutionary SPARCS cooling system you benefit from an engine which is reliable, efficient and powerful.

We patented a new rotary engine that delivers up to 10X more power, 30% more efficient than traditional piston engines, and a perfect fit for hybrid-electric applications.

Small engines with low emissions and high performance over competing engines make the Rotapower® a ideal powerplant for small 2-wheeled vehicles.

2024年6月10日 · An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally rotating piston and sleeve arrangement, making it lighter, simpler and...

Freedom Motors has developed both single and multi-rotor high performance engines and is producing a small number of 530cc displacement single rotor (530 series).

2014年12月5日 · MIT startup LiquidPiston has developed a rotary internal combustion engine that is smaller, lighter, quieter, and 20 percent more fuel-efficient than the ICEs used in many small-engine devices.

Ideal for boosting power in rc model cars and airplanes, reducing the weight of mid-size cars and airplanes, and providing reliable, user-friendly service in any application scenario. 2.6-grade precision 30-tooth internal gear and 20-tooth external gear, steel flywheel, reinforced crankshaft.

VOLS is a leading producer of small, fuel-efficient, and powerful rotary engines. Our innovative design and detonation combustion technology have eliminated the shortcomings of conventional rotary engines while maintaining all the advantages.

2014年11月24日 · A new 70cc rotary 4-stroke engine that’s a little bigger than an iPhone yet could pump out five horsepower was unveiled by LiquidPiston at last week’s SAE International/JSAE 2014 Small Engine Technology Conference in Italy.
