      Applications.

AB  - Free-piston engine generators (FPEGs) have huge potential to be the principal 
      energy conversion device for generating electricity from fuel as part of a 
      hybrid-electric vehicle (EV) powertrain system. The principal advantages lay in 
      the fact that they are theoretically more efficient, more compact, and more 
      lightweight compared to other competing EV hybrid and range-extender solutions 
      (internal combustion engines, rotary engines, fuel cells, etc.). However, this 
      potential has yet to be realized. This article details a novel dual-piston FPEG 
      configuration and presents the full layout of a system and provides technical 
      evidence of a commercial FPEG system's likely size and weight. The work also 
      presents the first results obtained from a project which set-out to realize an 
      operational FPEG system in hardware through the development and testing of a 
      flexible prototype test platform. The work presents the performance and control 
      system characteristics, for a first of a kind system; these show great technical 
      potential with stable and repeatable combustion events achieved with around 700 W 
      per cylinder and 26% indicated efficiency.
