The combustion chamber includes the cylinder liner and piston, where low temperature corrosion and abnormal abrasion can lead to serious troubles. Kirari NINJA will attempt to address this by explaining the exact condition of the combustion chamber interior.

NYK by combining photo data with operational data from the ship information management system (SIMS), as well as engine data from an electronic checklist, developed the software to diagnose internal chamber conditions.

Kirari NINJA has a 360 panoramic camera and lighting, which photographs in all directions of the interior.

NYK has also developed a smaller version of Kirari NINJA, which photographs smaller cylinders.
