iquidPiston, Inc., a Connecticut-based developer of advanced rotary diesel and multifuel internal combustion engines, has been given a Small Business Innovation Research (SBIR) contract with the United States Army to develop its X-Engine platform in order to power Small Tactical Power Generators ranging from 2.0 to 5 kW. The company had previously delivered a prototype Compact Artillery Power System for field-testing to the U.S. Army PM for Towed Artillery Systems. The Small Tactical Power Generators operate on military fuels such as JP8 or diesel. The system’s advanced power management and controls enable optimal X-Engine run-time and battery charging, resulting in longer life and increased fuel efficiency for longer military missions.
