A lot of current diesel engine damages are caused by poor combustion inside the cylinder spaces. As soon as marine surveyors are confronted with engine damage and several pistons, rings, liners, valves, and cylinderheads, they are asked to give their view about the nature and cause of the damage. In most of the cases, the combustion quality has to be investigated. A number of factors influence the combustion quality: - fuel quality, - fuel components, - lubricating oil quality, - type of lubricating oil, - engine design, - condition of engine components;- for propulsion engines: - propeller design, - ship's hull resistance. The parts which are to be investigated should preferably be uncleaned, in the same condition as that in which they were dismounted. The first view of the parts, immediately after they are dismounted can give the best information. It is always important to collect samples of the deposits, of the lubricating oil out of the engine sump, and the fuel out of the daily service tank. Sometimes a preliminary inspection is held when damage to valves, liners, or pistons is suspected. Such an inspection is done with an endoscope.
