The Chris-Marine Liner Condition Camera (LCC) is used for photography of the cylinder liner walls and piston ring pack in 2-stroke engines. The images captured by the camera 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
The Chris-Marine Liner Condition Camera has four cameras that document the complete liner running surface, exhaust valve and injector valves. There is no need to remove the cylinder cover to use the camera but through the opening at the venting of combustion chamber is necessary.
- Cameras 1-3: facing the liner walls in slightly overlapping sectors
- Camera 4: 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 to avoid unnecessary data collection and battery energy consumption
- Tablet camera: documents piston ring pack and top land condition
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. High-temperature resistant electronic components and batteries allow operation without lowering engine coolant temperature for most engine types.
