Portable Power Generation Based on Mesoscale Free-Piston Knock Engine.

摘要

The objective of this program is to develop and demonstrate a mesoscale free-piston knock engine operating on a variety of hydrocarbon fuels, such as propane, ethane, butane, and diesel. The goal is to deliver a 500 W pneumatic output in a 200 cu cm packaged volume, which can be used to power various mechanical systems, or to generate electricity via a high-speed air motor and generator. The overall engine efficiency goal is 44%, thus giving a hydrocarbon-based power source an energy of 55 Wh/kg.
