LiquidPiston, a Connecticut-based company, is advancing its development of a 10kW heavy-fueled generator prototype tailored for the U.S. military, following an $8.3 million contract awarded by the Army in 2023. The generator is powered by LiquidPiston’s innovative 25hp XTS-210 rotary engine, designed to meet the Department of Defense’s portable power requirements.
The XTS-210 engine boasts five times the power density of conventional piston diesel engines, while being nearly 80% lighter and more compact. This 25 horsepower, two-stroke, supercharged engine targets a specific fuel consumption rate of under 350 g/kWh, making it optimized for hybrid-electric applications.
Co-founder and CEO Alec Shkolnik expressed enthusiasm as the company begins testing the fully integrated generator, which is 75% lighter and one-quarter the size of the Army’s current Advanced Medium Mobile Power Source (AMMPS). The genset is designed to be man-portable, eliminating the need for vehicles for transport.
This generator incorporates essential components for efficient field power production, including the XTS-210 engine, a high-performance electric motor, custom power electronics, and military-grade packaging. It is also engineered to be compatible with existing AMMPS systems for seamless integration.
LiquidPiston’s patented High-Efficiency Hybrid Thermodynamic Cycle (HEHC) enhances efficiency by combining features from Diesel, Otto, and Atkinson cycles, utilizing high compression ratios and constant-volume combustion.
With over 82 patents and more than $60 million invested in research and development, LiquidPiston aims to leverage its technology in military, aerospace, and future markets, including industrial and automotive applications. The company’s innovations position it as a key player in the $400 billion internal combustion engine market and emerging mobility technologies.
