The article presents a part of the work done in a research and development project being made by SWIATEK Lech Swiatek company. It describes the comparison of different fuels used in piston engines with JET-A1 turbine engine fuel. Next, the proposed combustion process of JET-A1 fuel and a prototype one-cylinder engine are described. In details, a special cylinder head and direct injection programmable computer are presented. In the next part, a designed and built test stand is described. Finally, the results and conclusions are presented. The designed test stand enabled to perform assumed tests. The innovative JET-A1 combustion process was possible to perform and the power and torque were higher in 1900-3000 rpm range than with the gasoline fuel. The designed GDI programmable injection computer enabled to fully control the injection and ignition parameters.
