<P>PROBLEM TO BE SOLVED: To provide a more efficient free-piston engine-driven linear power generator. <P>SOLUTION: This free-piston engine-driven linear generator 10 includes at least one linear generator 12 provided with an engine unit 14 and a power generation unit. The engine unit 14 is provided with a piston 32 reciprocatingly disposed in a cylinder 30, and a combustion chamber 36 and an air chamber 34 provided on both sides of the piston 32 and having volume changed in association with the reciprocating motion of the piston 32. The power generation unit is the linear generator provided with the piston 32 and a coil 22 fixed on the outer periphery of the piston 32, and generating power in association with the reciprocating motion of the piston 32. The piston 32 reciprocates in the cylinder 30 by combustion pressure generated when burning an air-fuel mixture in the combustion chamber 36, and repulsive power of gas in the air chamber, compressed by the combustion pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
