CHRIS-MARINE®

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

The Chris-Marine Cylinder 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

Product features

  • The Chris-Marine Liner Condition Camera has four cameras that document the complete liner running surface, exhaust valve and injector valves without removing the cylinder cover:
  • 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 topland 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.
  • There is no need to remove cylinder cover or exhaust valve housing when using the LCC. Only venting of combustion chamber is necessary, e.g. by opening the indicator valve.
  • High-temperature resistant electronic components and batteries allow operation without lowering engine coolant temperature for most engine types.
  • Time required: ~15 min per cylinder unit
  • With fully charged batteries it is possible to document up to 14 cylinders (subject to number of pictures taken per cylinder).
