Liner Condition Camera / LCC
Camera that scans / documents the condition of the cylinder liner interface, exhaust valve, piston rings and piston crown.
The photos are used when evaluating cylinder condition parameters such as cleanliness of ring land, size of cylinder wear edge, cylinder honing mark and wave-cut groove extension, black lacquering from corrosive wear and bore polish.
- Camera unit: 4 cameras included to ensure accurate documentation
- Measurement time: ~/15 mins per liner
- Battery capacity: when fully charged it is possible to document up to 14 cylinders
Liner Condition Camera / LCC
A base ensures accurate positioning of the LCC unit. To insert and extract the LCC unit, a tool is used.
The LCC unit and its base are easily inserted through a scavenge air port.
A hand-held tablet, also compatible with the Chris-Marine LDM, is used to collect picture data from the LCC unit. It is also used to take pictures of ring pack and topland.

Liner condition camera greatly facilitates cylinder condition monitoring
The Chris-Marine Liner Condition Camera (LCC) has been designed for accurate and efficient photography of cylinder liner walls and piston ring pack in 2-stroke engines. Thanks to its unique design, the camera enables the user to take pictures of the entire liner, without removing the cylinder cover.
Not only will the documentation of the cylinder liner be more accurate. In addition, the time spend monitoring the cylinder will be significantly shorter.
The images captured by the camera are used when evaluating cylinder condition parameters like:
- cleanliness of ring land
- size of cylinder wear edge
- cylinder honing mark and wave-cut groove extension
- black lacquering from corrosive wear and bore polish
Camera features
Chris-Marine’s Liner Condition Camera has four cameras that together document the complete liner running surface, exhaust valve and injector valves.
Cameras 1-3: these cameras are facing the liner walls in slightly overlapping sectors
Camera 4: this camera is facing upwards, toward injectors and exhaust valve
Cameras 1-4 and LED flashes mounted on the camera unit are triggered with a laser distance sensor. Thanks to this system, the user avoids unnecessary data collection and battery energy consumption.
Tablet camera: this camera documents piston ring pack and top land condition
Liner Camera advantages
There are some major advantages with using Chris-Marine’s liner condition camera. To begin with, there is no need to remove cylinder cover or exhaust valve housing when using the LCC. Only venting of the combustion chamber is necessary, something that results in serious time and effort saved.
Another advantage is the high-temperature resistant electronic components and batteries in thee camera. They actually allow operation without lowering the engine coolant temperature, and this goes for most engine types.
The LCC unit includes all parts needed for in-situ cylinder condition documentation of 2-stroke engines with a bore size from 480 to 980 mm.
How long does it take to document the condition of a liner?
- Time required: ~15 min per cylinder unit
- With fully charged batteries it is possible to document up to 14 cylinders (depends on the number of pictures taken per cylinder).
