In this modern era, the application of various fields to a technology is something that cannot be avoided. One of them is on the UAV (Unmanned Aerial Vehicle) technology with a two-stroke engine as the main driver that will be modified by adding ECU (Electronic Control Unit). Knowledge in the field of electronic and control systems alone will not be enough in this case. The ability to analyze the characteristic and properties of two-stroke engine is required so the control parameters and their effects for this engine can be known. One way to achive that is to perform an engine simulation using Ricardo WAVE software. Model making and engine simulation had been carried out. The simulation data was compared with the test results provided by the manufacturer of the two-stroke engine and the differences was found in the value between the simulation results and the test data with error ranges up to 31% for torque, 27% for power, and 11% for fuel consumption rates. From the analysis, the difference occured due to the inexistance of the muffler component in the model. By using the right muffler configuration for diameter and length that matches the engine used, the performance parameters, especially torque and power can increase up to 64%. In this thesis report also explained the improvements that can be made to the model to obtain a more valid simulation result other than the addition of muffler components. In addition, a further analysis was also conducted on calculating the mole fraction of combustion products in Ricardo WAVE software and it was found that this software has able to predict the combustion products produced by internal combustion engine, especially CO, CO2, H, H2, H2O, N2, O, O2, OH and N.
