FIELD: internal combustion engines.
SUBSTANCE: invention relates to diagnosis of an internal combustion engine using a laser ignition system. 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 may be emitted at a lower power level during an intake and/or exhaust stroke to illuminate a cylinder interior while a photodetector captures images of the cylinder interior. 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 is reduction of complexity and labour input in engine diagnosis.
