The entire 40 hp engine is targeted to fit into a 10" x 8" x 8" box and weigh just 30 lbs. In this first phase of the program, LiquidPiston will build a test rig that will support future optimization efforts towards these objectives. Please see illustration: http://tinyurl.com/ztg3cl4.
"Our goal is to create a reliable X4 test rig that will support optimization of the X-engine architecture and the HEHC cycle. Combined, the cycle and architecture offer a compression-ignition, diesel-fueled rotary-engine power solution that is a fraction the size and weight of a comparable piston engine, while offering the advantages of greater fuel efficiency, quieter operation and reduced vibration," says Alexander Shkolnik, CEO and Founder of LiquidPiston.
"Today, a typical 30 kW military diesel generator weighs 2,700 lbs. Such a generator can be used to power a mobile command center, for example. Soldiers would benefit as the X4 prototype would enable an ultra-portable diesel generator that produces electricity in a package one-tenth the size and weight, and operates with greater efficiency," explains Shkolnik. "We seek to help reduce the military's logistical and carbon footprint. Our design would also give greater range and capability to drones or other vehicles. The same technology would benefit civilian consumers as well – lighter, quieter more efficient generators or auxiliary power units for homes, boats or vehicles, as well as range-extended electric vehicles."
LiquidPiston recently installed its 70cc X-mini rotary engine prototype into a go-kart demonstrator (see: https://vimeo.com/170502635), replacing a 40 lb, 6 hp gasoline piston engine with the 4 lb, 3-5 hp 70cc X-mini engine.
LiquidPiston develops compact, quiet, fuel-efficient, low-vibration, multi-fuel-capable combustion engines that are scalable from 1 hp to over 1,000 hp, based on the company's patented High Efficiency Hybrid Cycle and rotary X engine architecture. See: http://www.liquidpiston.com.
