An alternative source of on-board electricity generation in hybrid propulsion systems is a free piston engine. If the electrical machine can be fully integrated with the combustion engine, it may be able to offer a denser source of power conversion than conventional engines, fuel cells and batteries. This paper presents the modelling, development and testing of the linear engine generator concept, where a linear electrical machine is physically integrated within the compressor of a free piston engine. The challenges of mechanical integration of these two usually separate components to form a generator-compressor unit is discussed and demonstrated. The concept is shown to be capable of generating electricity whilst simultaneously compressing a working fluid such as air for use in the expander cylinder.
