Chris-Marine launches advanced camera for cylinder liner condition monitoring
Sweden-based marine engineering specialist Chris-Marine has announced the launch of its Cylinder Liner Condition Camera, LCC.
The LCC unit has four built-in cameras to enable photography of the complete liner running surface, cylinder cover, lube oil injection area, exhaust valve, start air valve and injector valves. It is capable of in situ cylinder condition documentation of 2-stroke engines with a bore size from 480 to 980mm without the removal of cylinder cover or exhaust valve housing
LCC is made up of high-temperature resistant electronic components and batteries allowing operation without lowering engine coolant temperature for most engine types. With fully charged batteries it is possible to document up to 14 cylinders and the time required per cylinder is approximately 15 minutes. Tools for centring, inserting and extracting the camera and checking clearance at TDC are included.
The images captured by the camera are used to evaluate cylinder condition parameters such as presence of cylinder honing marks and wave-cut groove extension, black lacquering and bore polish, size of cylinder wear edge and cleanliness of ring land. In addition, the pictures can be used to inspect exhaust valve, fuel injector valves, lube oil injection area and start air valve. LCC provides images from BDC (bottom dead center) to TDC (top dead center).
“The launch of our Cylinder Liner Condition Camera LCC is an important step for us and for our customers,” said Alexander Malt, Global Sales & Marketing Director at Chris-Marine. “We know that at least 10% of newbuildings need to have their cylinder liners replaced before the first dry-docking, a costly consequence of failing to keep the liners in top condition. However, this problem can easily be prevented and that’s where our camera comes into play. LCC detects and documents abnormal surface conditions and helps the engine crew determine if measures need to be taken. By monitoring the condition of the liner regularly, severe damage to the engine can be prevented and unnecessary investments avoided, Alexander Malt continues.”
