A preliminary study of spark-ignition system for free piston linear engine

This paper presents a model of a two-stroke, spark-ignition freepiston engine converted from two small two-stroke engines. It has a bore size of 34 mm and a maximum stroke of 28 mm. The linear engine uses gasoline fuel that is available on the market. The purposes of the research show a model of the starting system, investigation the effects of spark timing, and effective pressure.
