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

FIELD: mechanic engineering; electrical engineering.

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 contains a body, an insulator, a microchip laser installed in the cavity inside the insulator, a vacuum tube connected to it, optical window, a focusing lens, an ignition cell with cylindrical and conical cavities, a washer with a hole – between the optical window and the ignition cell and a target installed in one of the ignition cell cavities on the holder, several outlets entering the conical cavity. In the cylindrical cavity of the ignition cell on the central support on the bearing an impeller of the aerodynamic turbine is mounted.

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