<P>PROBLEM TO BE SOLVED: To provide a simply constituted linear-generation free-piston engine capable of performing combustion starting. <P>SOLUTION: The linear-generation free-piston engine 10 includes: an engine unit 12 in which a slidable piston 16 and two combustion chambers 18a and 18b sandwiching the piston 16 are provided in a cylinder 17; a power generation unit 14 which comprises a permanent magnet 50 provided in the piston 16 and a power generation coil 52 fixedly set around the permanent magnet 50; and a control part for controlling the drive of the engine unit 12. When starting the engine unit 12, the control part ignites a combustible gas mixture after positioning the piston 16 in a starting range as a position range of the piston 16, in which theoretical work obtained by an initial explosion is larger than various losses generated at the starting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
