DEVELOPMENT OF A TWO-STROKE FREE PISTON ENGINE FOR THEAPPLICATION OF A LINEAR GENERATOR

Abstract

A free-piston engine (FPE) for the application of linear generator (LG) is developed. The development involved extensive modeling and simulation works before the actual prototype is built. Several testing are conducted for each subsystems of the LG-FPE. The first testing is aim to provide a benchmarking with regards to the injection current into the linear generator coil when different amount of voltage (with different amount of 12V battery quantity). Next, the tests progressively venture into the in-cylinder behavior while varying the voltage. From the experiments, it was found that the 5- battery configurations of LG-FPE resulted in compression pressure of around 5 bar in both cylinders while the translator speed achieved is around 300 cycle per minute. These parameters achieved its threshold values which will successfully start the engine.
