The aim of this study was to investigate the trend of the engine performance according to the Gul & Co - Motor development using cycloid crank-connecting rod instead of the conventional crankshaft. Since the Gul & Co motor aims at the double piston engine with stroke reduction, a preliminary investigation of the Gul & Co concept, including the piston stroke effect on the engine performance is needed. Furthermore, the investigation of the general performance of a double piston engine with diameter reduction would give a helpful additional infoffi1ation. In order to further evaluate the Gul & Co concept, a preparatory approximation of the engine design by using the cycloid crank-connecting rod instead of conventional crankshaft is needed, and the engine performance comparison should be performed. The method used was the simulation of the engine performance by using non dimensional Filling-Emptying model. In its basic form, this model requires the rate of combustion as an input to the calculation. However, such model allows general engine design changes to be investigated with moderate computational requirements. The cycle simulation is designed to predict details of the thermodynamic properties of the working fluid and general engine performance over a broad range of operating and design conditions, including valve timing, spark ignition timing, engine cooling conditions etc
