LASER IGNITION SAFETY INTERLOCK SYSTEM Russian patent published in 2018 - IPC B60W20/00 F02P23/04 G01M15/04 G07C5/08 

FIELD: physics.

SUBSTANCE: method and system are provided for using a laser ignition system and performing visual inspection of an engine and diagnose various cylinder components and conditions based on engine positional measurements. Laser pulses can be emitted at a lower power level during an intake and / or exhaust stroke to illuminate the inside of the cylinder, while the photodetector captures images of the inside of the cylinder. Additionally, laser pulses can be emitted at a higher power level, additionally, laser pulses may be emitted at a higher power level to initiate cylinder combustion while the photodetector captures images of the cylinder interior using the light generated during cylinder combustion.

EFFECT: technical result consists in reducing the time of visual control by capturing images inside the cylinder, without reducing the thoroughness of the control.
