When the oil consumption of a ship’s auxiliary power generator’s system increases
abnormally, excessive lubricating oil will enter into the combustion chamber, which will
cause combustion deterioration, serious pollution of piston, cylinder, gas valve, exhaust
pipe, and even coking, causing the piston ring to become stuck and affecting safe
production.Taking a case of failure of increased daily lubricating oil consumption in a ship
’s auxiliary power generator, it analyzes the common causes of increased oil consumption and
the faults are also checked.It is concluded that the increased fuel consumption of the ship’
s auxiliary power generator of this type is not because of the oil system itself, but the
imperfect manufacturing process of the piston ring.Therefore, in the process of purchase and
acceptance of spare parts, it is necessary to strengthen review and choose premium ones.It
needs to carry out routine inspection of oil consumption, lifting cylinder inspection, piston
ring clearance, wear measurement, etc., to timely detect faults and solve them to ensure ship
’s safe navigation.
