Abstract

The invention relates to a fuel gas type free piston linear engine. The fuel gas type free piston linear engine comprises an I-shaped piston and a cylinder body, wherein the cylinder body is symmetrically provided with a left air inlet cavity and a right air inlet cavity as well as a left exhaust gas cavity and a right exhaust gas cavity; the I-shaped piston comprises a compression piston, a leftair inlet piston, a right air inlet piston, a left exhaust piston and a right exhaust piston; and the I-shaped piston is arranged in the cylinder body; the full air intake is guaranteed through differential pressure air intake, and the sufficient air exhaust is guaranteed through differential pressure air exhaust; the air intake, compression, combustion and expansion process is continuously and alternately realized, a magnet fixed on the piston performs horizontal reciprocating motion along with the I-shaped piston, magnetic force line cutting is realized between the magnet and a power generation coil, and power generation is realized. The fuel gas type free piston linear engine is simple in design and layout structure and is suitable for miniaturized and portable development.

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 ...
