LASER SPARK PLUG Russian patent published in 2018 - IPC H01T13/20 F02B19/12 F02P23/04 

FIELD: machine building.

SUBSTANCE: invention relates to power machines, specifically to laser spark plugs with an ignition cell, and can be useful in transport and heat power engineering. Laser spark plug comprises a housing, insulator, microchip-laser, installed in the cavity inside the insulator, vacuum tube connected to it, optical window, focusing lens, pre-chamber with a conical cavity, flat with a central hole – between the optical window and the pre-chamber and target installed in the pre-chamber cavity, several outlets entering the conical cavity. Flat is made with an inner surface having a parabolic shape, the target is made in the form of a ball and is mounted on an axis, the working blades of an aerodynamic turbine are fixed on the axis.

EFFECT: increase of service life of the laser spark plug by preventing contamination of the optics and the laser beam outlet.
