Description

The invention relates to mechanical engineering, in particular to engine generators and can be used as autonomous power sources in the energy sector and in transport.

The purpose of the invention is the reduction of dimensions and mass.

In FIG. 1 schematically shows the device and principle of operation of the engine-generator; figure 2 - switching circuit reed switches: a - rectification, b - sequentially and c - parallel to the generator coils.

Cylinder 1 with a piston 2, coils of a linear generator 3 and 4 with anchors 5 and 6 and reed switches 7 and 8, anchors are fixed to the piston 2 by means of brackets 9 and 10, purge generator chambers 11 and 12 communicate via combustion channels 13'and 14 with combustion chambers engine consisting of _; from the inner surface of cylinder 1 and piston 2 (double-acting), reed switches 7 and 9 are installed at the extreme dead points (at the level) - in coils, i.e. given the approach of anchors to these points.

The engine generator operates as follows.

When the piston 2, and with it the armature 5, approaches the upper points in the combustion chamber (L), the compression of the combustible mixture occurs and it ignites. Reed switches 7 at this time switch the coils to the desired mode, i.e. straightening, sequential or. the coils are connected in parallel, at the same time, the repi- i switch is switched by the anchor 6. When the mixture (L) of the chamber ignites under the action of gases, the piston moves in the opposite direction (to the right combustion chamber (P), and the armature 5 blows at this time ( by their movement) through the channel 13, the combustion chamber (P) and helps to fill this chamber with a combustible mixture, after filling the chamber (P) and the anchors approach the reed switches 8, they switch the desired mode of the electric current of the coils, and the combustion chamber ignites the combustible mixture and the gases push piston 2 in the opposite direction, etc.

The claimed technical solution allows to achieve the goal.
