“…Wankel engines also have multi-fuel capability [9] and can operate in either a direct injection mode [10] or a port fuel injection mode [11]. The effect of the synthetic fuels (bioethanol) on the performance and emissions of a Wankel engine was conducted by Siadkowska et al [12].…”

“…The gasoline LHV value of 43,000 kJ/kg was used for calculations [13]. Measurement of the fuel consumption was realized by placing the fuel tank on the Shinko Denshi Vibra AJ-12KCE electronic balance and determining the mass of fuel consumed under the determined engine operating conditions during the registration of energy supplied to the storage system.…”

“…To achieve high efficiency, they are built based on a combustion engine with a small number of cylinders (often two) directly coupled with a brushless electric machine with excitation from permanent magnets. In order to reduce vibrations of the assembly, the engine is often equipped with a balancing shaft, sometimes a V-arrangement of cylinders is used, or even a rotary piston engine -Wankel type [13].…”

Research on the effects of the use of the range extender developed for a small commercial electric vehicle was presented in this paper. The range extender has a maximum output power of 2.65 kW. The developed auxiliary power unit consists of a three-phase generator propelled by an industrial low-power spark-ignition engine. The exhaust system was improved using a more efficient muffler. The implemented motorcycle muffler has a three-way catalyst (TWC) integrated inside. The use of the more advanced exhaust system aimed at reducing noise and exhaust emissions of the range extender. The efficient operation of the three-way catalytic converter requires a stoichiometric air-fuel ratio. To enable desired air-fuel ratio a fuel system was modified. In the first stage of research, the effects of improvements of the exhaust system on the range extender noise emissions were quantified. The next step covered the research of the fuel conversion efficiency, the exhaust gas composition, and the efficiency of conversion of the three-way catalyst. A significant decrease of noise and toxic gas emissions and an increase in the fuel conversion efficiency were revealed. The mentioned research was conducted in stationary conditions. After that, in the final part research of the running vehicle with the range extender on was made. The beneficial outcome of these tests enabled the development of a set of rules of the control of the range extender.

“…Part of research focuses on the use of alternative fuels in already existing internal combustion engines, e.g. synthetic fuels in a Wankel engine [17] or the modification of engine assistance systems to reduce emissions [6]. The use of a compression ignition engine in light aviation is also being considered and such aircraft are already in service [19].…”

This paper presents an analysis of selected propulsion units dedicated to test stands for unmanned aircraft systems. It focuses on engines suitable for aircraft with a maximum take-off mass up to 150 kg. The study includes an analysis of propulsion units that can be used to power systems on stationary test stands dedicated to advanced research and measurement of prototype aerospace technologies intended for use in rotorcraft. The analysis of propulsion units shows that electric units are a better choice for powering UAV rotorcraft test stands. Their main advantages include the possibility to simplify the construction of the device by eliminating gears and to mount the motor in a vertical position, simpler power supply, cooling and control systems and the lack of an exhaust system. Additional advantages are undoubtedly lower vibration generation, cheaper and easier operation as well as better comfort.
