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

FIELD: power 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. Task of creating an invention corresponding to 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 cavity inside insulator, vacuum tube connected to it, optical window, focusing lens, prechamber with cylindrical cavity, turning into conical, limited by conical wall and end bottom, washer with central hole – between optical window and prechamber, several outlet openings on conical wall, in that birotate turbine is installed on inner surface of cylindrical cavity inside cylindrical cavity, and axial hole is made on end bottom.

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