The Behaviors of Three Different Transmission Systems between a Hybrid Engine and a Generator

This experimental study was aimed to propose generator transmission systems driven by a hybrid engine which could be fueled with gasoline, LPG or biogas. To study the highest work transmitted from the hybrid engine to the generator; a magnet motor was chosen as the generator in this research because of its few significant characters, three different transmission systems; (1) the pulley (belt system), (2) the screwed shaft and bush and (3) the flanged shaft and bush, connected between the engine and the generator were experimentally investigated. The produced voltages from the generator connected with the biogas engine coupled with the pulley (belt system), screwed shaft and bush and flanged shaft and bush, were 14.84 Volts, 14.10 Volts and 11.82 Volts, respectively, or 99.26%, 95.21% and 81.40% of the average voltages obtained from the generator driven by the gasoline engine. This work emphasized the effects of transmission systems connected between the engine and the generator; proposed transmitter was the screwed shaft and bush and we also insisted that biogas engine could drive small households.
