Jin XIAO, Yingdong CHENG, Jinlong WANG, et al. An experimental study of a single-piston free piston linear generator. p916-930
To mitigate the environmental and health problems caused by vehicle emissions, free piston linear generator (FPLG) is considered as an alternative solution which can be realized in the near future. It can be regarded as a device consisting of a crankshaft-less internal combustion engine, a linear electric machine and a rebounding device like gas spring. Because of the absence of the crankshaft restriction, its compression ratio is variable and controllable without modifying the mechanical configuration, so that it is available for various fuel, especially the clean fuel such as the ethanol, hydrogen, methane and natural gas and so forth. Consequently, FPLG receives increasing attention from the public.
