A lab-scale prototype of Linear Joule Engine has been developed with the optimized design parameters from previous studies. The Linear Joule Engine applies free-pistons in double acting cylinders and Joule Cycle with an external combustor or heater as heat addition component in the cycle. It offers an alternative prime mover technology using different low carbon or zero carbon fuels, e.g. hydrogen, bio-methanol, ammonia, etc. in the energy transition period. A series of preliminary experiments was conducted to reveal the relationships between moving mass, valve timing, supply pressure and dynamic equilibrium. The experiment results were also used to provide guidance on the prototype design of linear alternator and heat addition component. A scaled-up and modularized Linear Joule Engine system integrated with linear alternator would have an exciting potential to be used as ship main engine, range extender of hybrid vehicles, etc.
