Problems solved by technology

On the basis of the existing structure, the present invention adds an auxiliary motor on both sides of the generator, and the auxiliary motor and the generator are installed together. Due to the assistance of the auxiliary motor, the generator does not need to perform mode conversion, which solves the problem of generator conversion. Because of the long response time of the motor mode, at the same time, because the auxiliary motor can provide power in time, it avoids the problem of the failure of the piston to reach the designated position due to insufficient power due to misfire, and ensures the stable operation of the free-piston linear generator

Abstract

The invention discloses a single-cylinder opposed double-piston free-piston linear generator and a double-piston free-piston linear generator, including a generator, two sets of two-stroke engines, a first auxiliary motor, a second auxiliary motor, a first auxiliary motor, and a second auxiliary motor Symmetrically arranged on both sides of the generator axis, the auxiliary motor 1 and the auxiliary motor 2 are connected to the generator, the auxiliary motor 1 and the auxiliary motor 2 are connected to the two-stroke engine, and the two-stroke engine includes a cylinder block, a cylinder head, a spark plug, and a fuel injector , piston, crankcase kit, connecting rod, auxiliary motor 1, auxiliary motor 2 are set coaxially with the generator, the generator is connected with auxiliary motor 1 and auxiliary motor 2, the stator of the generator is connected with the auxiliary motor 1 stator, and the auxiliary motor 2 stator is the most A predetermined axial distance is respectively set between two adjacent windings. The invention solves the problem of long response time for the switching of the working mode of the motor, ensures that the piston reaches the designated position smoothly, and enables the free-piston linear generator to run stably.

Description

technical field [0001] The invention relates to the technical field of range extenders for new energy vehicles, in particular to a single-cylinder opposed double-piston free-piston linear generator. Background technique [0002] In the prior art, the structure of the free piston linear generator (FPLG) has a two-stroke double-piston structure. The back-mounted double-piston structure is equipped with a two-stroke engine at both ends of the generator core shaft. The two-stroke engine is symmetrically arranged, and the crank connecting rod mechanism is omitted. A generator is connected between the two two-stroke engines. The motor is connected to the engine, and the motor has two functions of motor and generator at the same time, but the disadvantage is that because FPLG omits the crank connecting rod mechanism, FPLG has the difficulty of controlling the piston movement, which leads to the position of the top dead center during the operation of FPLG. Variable, the engine comb...
