Dynamic Simulation of a Two-Stroke Spark Ignition Free-Piston Engine Generator

Abstract:

In order to study characteristics of a two-stroke spark ignition free-piston engine generator (FPEG), a dynamic simulation model which derives from several dynamic and thermodynamic equations is built in Matlab/Simulink . Simulation results show that: comparing to conventional engine, FPEG has advantages on efficiency and NO_x emission level. By varying the moving mass, the compression ratio will increase accordingly while frequency keeps nearly constant. By varying ignition point, an optimum ignition advance is available in each case. At last, performance of free-piston engine generator under different fuel supply and load is predicted.
