A high exhaust temperature on a single cylinder points to that unit's combustion, injection or exhaust valve — a deviation from the others is the key diagnostic clue.
Marine MachineryWhat is the difference between a purifier and a clarifier?

Marine MachineryWhat is an indicator diagram and what does it tell the engineer?
An indicator diagram plots the pressure inside an engine cylinder against volume or crank angle, letting the engineer assess the power, condition and faults of each cylinder.
Marine MachineryHow does a ship's fuel oil system store, treat and deliver fuel to the engine?
