Power Reimagined
Compact, Quiet, Low-Vibration, High-Efficiency Rotary Engines
LiquidPiston develops advanced rotary engines based on the company’s patented HEHC
thermodynamic cycle and engine architecture. LiquidPiston engines are designed to be:
X Mini 70cc 4-stroke SI engine
Lightweight and Compact
• High power density - up to 1.5 hp/lb (2.5 kW/kg)
• 30% smaller and lighter for spark-ignition (SI) gasoline engines
• Up to 80% smaller and lighter than compression-ignition (CI) piston diesel engines
Quiet
• No poppet valves
• Exhaust turbulence minimized by over-expansion; no muffler required
Low-Vibration, Low-maintenance, Reliable
• Only two primary moving parts, optimally balanced / near-zero vibration
High-Efficiency
• 50% decrease in fuel consumption possible for SI gasoline engines
• 30% decrease in fuel consumption possible for CI diesel engines
Multi-Fuel Capable (Spark Ignited), or Heavy Fueled (Compression Ignited)
• Diesel, gasoline, natural gas, Kerosene / Jet-A / JP-8.
Scalable
• From 1 hp to over 1000 hp

你预定集资建厂吗

  不是，我要买一台，装在直升机上

             放心  国内没有工厂愿意生产，首先在油改电的大趋势下产量没保证.............

爆燃的那个瞬间是对向的刮片部分线受力，负荷有点太集中，密封问题，偏磨问题，但转子发动机这么多年，想来这些应该都不是事了吧，此外就是汽油时代都快结束了，这玩意儿才冒个头....

感觉这玩意这么设计应该还是存在哪里的硬伤，要不然看其历史也发展有10-20年，真牛鼻的话应该早就烂大街了！
