3.2 Treatment of detergent type lubricating oils The main function of detergent lubricating oil is to keep solid contaminations in suspension and prevent both their agglomeration and deposition in the engine. This function reduces ring sticking, wears of piston rings and cylinder liners, and generally improves the cleanliness of the engine. agglomeration

Air at high pressure, i.e. at 25 bar or more, is required for starting main and auxiliary engines in motorships. Air at low pressure, say at 6 bar or less is required for much remote or temperature or pressure controlled equipment, for which purpose it must be clean and oil-free

There are branch pipes to the separators and occasionally to the settling tanks (blanked). Other branch pipes lead to the deck filling lines (also blanked) so that the oil can be discharged ashore

Provide for data logging, remote control and automatic action-pneumatic electro￾pneumatic, and electronic equipment, self￾regulating apparatus, etc. The chapter will give a general instruction above system and function. The other chapters of the book focus on the oil handling devices onboard
