The X Mini is an engine that will enable many small engine applications to be smaller, lighter, and quieter. The engine’s improved noise, vibration and harshness (NVH) characteristics will also increase product performance, enhance operator comfort and prolong application life. The X Mini has the potential to enable entirely new applications not possible with current engine technology, and will improve applications such as:

  • Handheld power equipment
  • Lawn and garden equipment
  • Portable generators
  • Mopeds
  • Unmanned aerial vehicles/drones
  • Robotics
  • Range extenders for electric vehicles
  • Auxiliary power units for boats, aviation and other vehicles

Additionally, last March, LiquidPiston signed a $1 million agreement with DARPA to develop fuel-efficient, lightweight, heavy-fueled, rotary combustion engine for the U.S. Military.
