POLY-GENERATION SYSTEM

According to an aspect of the present invention, there is provided A poly-generation system comprising: at least one cylinder which forms a combustion chamber; a piston provided in the cylinder and configured to reciprocate; an engine rotor which comprises an engine magnet and reciprocates in conjunction with the reciprocation of the piston; an engine stator which comprises an engine coil and outputs an electromotive force induced in the engine coil due to interference with the engine magnet to the outside; and a generator which is integrally coupled with the piston and generates electricity using an inertial force generated by the reciprocation of the piston, wherein the generator comprises: an elastic member deformed by the inertial force; a generator rotor which comprises a generator magnet and reciprocates due to the deformation of the elastic member; a generator stator which comprises a generator coil and outputs an electromotive force induced in the generator coil due to interference with the generator magnet, and a generator battery which stores the electromotive force induced in the generator coil.
