Problems solved by technology

[0002] Since the appearance of the free piston engine for more than half a century, although there are many advantages, there has been no conventional product
The main reason is that it is inconvenient to start, it is easy to stall during operation, and the left and right pistons are out of sync.

Abstract

The invention discloses an electric-started free piston linear engine. Two power pistons are oppositely positioned in a cylinder of the engine, and are separately connected with a pressure air piston and a rotor of a linear motor. The linear motors serve as starting motors of the engine; and after the engine is started, a controller switches to a working state of a generator to charge an accumulator. When the engine is started, the left and right linear motors pull the left and right power pistons to perform a reciprocating motion in a range of inner and outer stop points to perform air suction, compression and fuel injection by a fuel injection nozzle to generate combustion and expansion; after the engine is started, air in left and right air cushion chambers is compressed and stored as energy of enabling the pistons to move to the inner stop points; and when the expansion is finished, the right power piston opens an exhaust hole, so that a lot of fuel gas flows into a gas turbine to continuously expand to output power. As the linear motors are used as the starting motors, the engine is conveniently started, and the linear motors also can serve as generators; the engine is not liable to generate flameout; and the two power pistons can be synchronously corrected.

Description

technical field [0001] The invention relates to an electric start free piston engine, in particular to the field of special engines. Background technique [0002] Since the appearance of the free piston engine for more than half a century, although there are many advantages, there has been no conventional product. The main reason is that it is inconvenient to start, it is easy to stall during operation, and the left and right pistons are out of sync. Contents of the invention [0003] The invention provides an electric-start free-piston engine. Two power pistons are opposed to each other in a cylinder of the engine, and the two power pistons are respectively connected to a compressor piston and a mover of a linear motor. The linear motor is used as the starting motor of the engine. After the engine is started, the controller switches to the working state of the generator to charge the battery. When the engine is started, the left and right linear motors pull the left and...
