Claims

[Scope of utility model registration request]

A free piston with one end facing the high-pressure gas chamber and the other end fitted into the hydraulic oil compression chamber, a high-pressure gas tank connected to the high-pressure gas chamber via a control valve, and an actuating piston housing the actuating piston. A cylinder partitioned into a combustion chamber and a working chamber by a piston, a fuel injection valve provided in the combustion chamber, and a communication pipe communicating the hydraulic oil compression chamber and the working chamber of the cylinder, Compressed air is supplied from the high-pressure gas tank to the high-pressure gas chamber to operate the free piston, and the free piston forces the hydraulic oil in the hydraulic oil compression chamber to the working chamber of the cylinder through the communication pipe, and is activated by the hydraulic pressure in the working chamber. In a rapid compression combustion device that operates a piston to rapidly compress gas in a combustion chamber, a polygonal rod is connected to the rear of the operating piston, and
A rapid compression combustion device characterized in that a guide hole is formed in the end plate at the rear of the working chamber of the cylinder, into which the rod is inserted so that it can slide only in the axial direction.
