<P>PROBLEM TO BE SOLVED: To provide a free piston generator adapted to simply and effectively improve its efficiency. <P>SOLUTION: The free piston generator 10 includes: an engine unit 16 that has a combustion chamber 26 for burning fuel at least on one side of a piston 20 and linearly moves the piston 20 by combustion pressure when fuel is burnt in the combustion chamber 26; a power generation unit 14 for generating power with the reciprocating movement of the piston 20; and a control part 50 for controlling the driving of the engine unit 16 and the power generation unit 14. The control part 50 adjusts a power generation load in order to maintain the piston speed near the top dead center, where the piston 20 is located closest to the combustion chamber side, within a specified speed range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
