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

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 cylindrical and conical cavities, flat with a central hole – between the optical window and the pre-chamber and target installed in one of the pre-chamber cavities, several outlets entering the conical cavity. Flat is made with an inner parabolic surface, the target is made in the form of a ball and is mounted on the shaft with the possibility of rotation and the working blades of the aerodynamic turbine are fixed to the shaft.

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