TREATMENT OF THE SYSTEM OIL IN MEDIUM SPEED AND

In medium speed engines, sulphuric acid entering the lube oil (either in the cylinderor in the crankcase via blow-by) is neutralized by the over-based additives withformation of calcium sulphate. As a result, the BN of the system oil is reduced.

TREATMENT OF THE SYSTEM OIL IN MEDIUM SPEED AND

As a result, the lubricant of medium speed engines is contaminated to a much larger extent with combustion products and fuel than the system oil of crosshead engines. In crosshead engines, a mixture of (used) cylinder lubricant, wear debris and to a lesser extent also partly burned fuel is formed in the scavenge air space above the stuffing box.
