Abstract

The free piston linear generator (FPLG) is a kind of linear free-piston engine and has many advantages over the conventional internal combustion engine. In this study, a novel two-stroke free piston linear generator prototype equipped with a linear electric generator is presented to achieve efficient conversion of mechanical work to electricity during expansion process. Different features of the prototype and their influence on the system performance are discussed. The ignition position set at 20mm, the injection position was fixed at 0 mm, i.e. middle of stroke, the injection pressure was set at 18 bar, and equivalence ratio for all experimental observations. It is noticed that for ER 1.8 maximum area under the curve is achieved indicating the work done by the gas on the piston is higher resulting in proper mixing and efficient combustion. The highest velocity and power produced are at equivalence ratio 1.6.
