Embodiment 1

[0020] The invention relates to a free-piston internal combustion linear generator with controllable dead center. Mainly includes: free piston internal combustion engine, linear generator, disc control mechanism 13 and connecting rod 9; free piston internal combustion engine includes: engine cylinder 1, piston 2, intake valve 3, exhaust valve 4, fuel injector 5, intake and exhaust Air controller 6; Linear generator comprises: motor mover 7, motor stator 8; Disc control mechanism 13 comprises disc 10, shaft 11, motor 12, groove line 14, as figure 1 shown.

[0021] On the disc 10, there is a motion groove line 14 in advance, such as figure 2 As shown, the groove line 14 coincides with the curve shape of one movement cycle of the piston, such as image 3 shown.

[0022] The connection relationship is: the free-piston internal combustion engine and the linear generator are connected in sequence to form a free-piston linear generator; the free-piston linear generator is symmetr...

Abstract

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: the free 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.

Description

technical field [0001] The invention relates to an energy power engineering mechanical device, in particular to a free-piston internal combustion linear generator with controllable stop point, which belongs to the field of energy power. Background technique [0002] The free-piston internal combustion linear generator is a new type of energy conversion device formed by coupling a free-piston engine and a linear generator. The driving force of the internal combustion linear power generation device studied at present - the internal combustion engine part generally adopts a two-stroke internal combustion engine, and its piston movement is not limited by the crank connecting rod mechanism, there is no fixed upper and lower dead center, and the compression ratio is variable, so it can be applied to a variety of fuels Combustion requirements can achieve low emissions of NOx and particulate matter. However, there is no relatively mature method to achieve precise control of the top...
