A Preliminary Study of a Two Stroke Free-Piston Engine for Electricity Generation

Vehicle contributes greatly to the rapid and strong economic development and other aspects of society. Besides, the operation of the transport impact on health and the environment seriously. Therefore, the study of solutions to improve fuel efficiency and environmental protection is one of the most focusing issues. The main objective of this paper is to present the theoretical fundamentals related to the design and development of a two-stroke free-piston engine (FPE) for electrical power generation. In this study, the prototype engine has been conducted with a power of 1.5kW, a bore size of 34mm, and a maximum possible stroke of 28mm using gasoline as fuel. In the future, this engine will be going to take advantage of excess biogas to generate electricity for production activities and daily life. The research has completed the initial intentions such as a theoretical investigation, calculation, determination of the engine model, and starting mechanism. Preliminary results have confirmed the feasibility of proposing the FPE model.
