LASER SPARK PLUG Russian patent published in 2018 - IPC F02B19/12 F02P23/04 H01T13/40 

FIELD: power machines.

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. Task of the invention, corresponding to the achieved technical result, is to extend life of laser candle by preventing contamination of optics and laser beam outlet. Solution of these problems is achieved in laser spark plug containing 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, turning conical, limited by conical wall and end bottom, washer with central hole – between optical window and prechamber, a plurality of outlet openings on a conical wall, with a spinning device rotatably mounted within the cylindrical cavity on the inner surface of the cylindrical cavity, and an axial hole is made on the end bottom.

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