Dead point controlled free piston internal combustion linear generator

The invention relates to a dead point controlled free piston internal combustion linear generator, belonging to the field of energy power. The dead point controlled free piston internal combustion linear generator mainly comprises free piston internal combustion engines, linear generators, a disc control mechanism and a connecting rod; a connection relation among the components is as follows: thefree piston internal combustion engines are sequentially connected with the linear generators to form free piston linear generators; two free piston linear generators are symmetrically arranged on a straight line passing through the circle center of a disc, and the disc is connected with an electromotor through a shaft; the disc is excavated with a motion trough-line in advance, and the trough-line is coincident with the curve shape of one motion cycle of a piston; an internal trough-line of the disc is in contact with and connected with the connecting rod of a free piston engine to play roles in free piston resetting and upper dead point controlling. The dead point controlled free piston internal combustion linear generator disclosed by the invention makes use of the disc control device,thereby achieving the purpose of controlling a dead point of the piston. The disc has high balancing property and good stability during working, and therefore synchronous operation of multiple cylinders can be realized.
