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 the achieved technical result, is to increase the life of the laser candle by preventing contamination of the optics and the laser beam outlet. Solution of these problems is achieved in a laser spark plug containing a housing, isolator, microchip laser installed in the cavity inside the insulator, an optical window, a focusing lens, a prechamber with a cylindrical and conical cavities and a target, installed in one of the cavities of the prechamber on the holder, a number of outlets entering the conical cavity, characterized that in the cylindrical cavity of the prechamber a twist device is installed on a cylindrical wall.

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