Abstract

The invention discloses an oppositely-arranged four stroke free piston internal combustion-linear electricity generating integrated device. The oppositely-arranged four stroke free piston internal combustion-linear electricity generating integrated device comprises a four-stroke internal combustion engine, two linear motors, a reversible electric energy storing device, an electric power unit and an electronic control unit, wherein each linear motor has an electricity generating working mode and an electric working mode, the electric power unit is used for connecting the linear motors and the reversible electric energy storing device, the electronic control unit is respectively connected with a valve timing mechanism, an ignition device and the electric power unit of the four-stroke internal combustion engine, active cells of the linear motors are fixedly connected with two pistons of the internal combustion engine, the active cell of each linear motor is provided with a position detecting component which is connected with the electronic control unit, the two ends of a combustor cylinder of the four-stroke internal combustion engine are open, the two pistons are symmetrically arranged inside the combustor cylinder, and the two linear motors are symmetrically arranged inside the combustor cylinder. The oppositely-arranged four stroke free piston internal combustion-linear electricity generating integrated device is good in operation dynamic balanced performance and high in scavenging efficiency.

Description

[0001] technical field [0002] The invention belongs to the technical field of internal combustion engine power generation, in particular to an opposed four-stroke free-piston internal combustion-linear power generation integrated device that can directly convert the chemical energy of fuel into electric energy for output. Background technique [0003] The two themes of protecting the environment and saving resources are driving human beings to explore and research new energy conversion devices with high energy conversion efficiency and good environmental protection. Free-piston engine (Free-Piston with Linear Generator) or Linear Combustion Engine (Linear Combustion Engine) is a new type of power system developed in the past 30 years. The reciprocating motion of the free piston in the system is mainly converted into two kinds of energy, one is electric energy ; The other is hydraulic energy. [0004] The two-stroke working cycle commonly used in free-piston engines at hom...
