Abstract

The invention relates to a gas-fired free piston linear generator, which includes an I-shaped piston and a cylinder body; the cylinder body is respectively symmetrically provided with a left air intake cavity, a right air intake cavity, a left exhaust gas cavity, and a right exhaust gas cavity; The I-shape includes a compression piston, a left intake piston, a right intake piston, a left exhaust piston and a right exhaust piston; the I-shaped piston is installed in the cylinder; the pressure difference is used to ensure the filling of the intake air , using differential pressure exhaust to ensure the adequacy of exhaust. The process of air intake, compression, combustion and expansion is continuously and alternately realized. The magnet fixed on the piston reciprocates horizontally with the I-shaped piston, and realizes the magnetic force line cutting between the power generation coil to realize power generation. The design, layout and structure of the device are simple, and are suitable for the development of miniaturization and portability.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular to a gas type free-piston linear engine. Background technique [0002] With the popularity of electric vehicles, solving the problem of the short range of electric vehicles has become the most challenging step in the development of electric vehicles. Among the many solutions, the industry's most recognized solution is to use an extended-range engine to charge the battery. At present, the most widely used range-extended engine is the traditional internal combustion engine, but due to the large volume of the traditional crank-connecting rod engine, difficulty in improving efficiency, and emissions, it is difficult to meet the power requirements of electric vehicles. Based on the higher requirements for range-extended engines, internal combustion engine researchers began to develop new range-extended engines, among which the free piston engine is one of them. [0003] Since there is ...
