CONDITIONS OF CONTINUOUS OPERATION OF OIL IN DIESELS,
Abstract
The maintenance and operation of lubricating oil systems in marine diesel engines are discussed. Clarification of oil by running it periodically of continuously through a centrifuge is recommended. Centrifuges of automobile type can also be used for clarifying oil on river motor-ships. In addition, lubricating oils must periodically be tested for contents of fuel residue and water. For this purpose the motor-ships must be equipped with laboratories. In general, a 4-pct content of fuel oil in lubricating oils can be admitted. This content can be tested by measuring viscosity. For instance, at 4-pct fuel content the viscosity of M12V lubricating oil is lowered to 9.5 centistokes at 100C. The flash point of this lubricating oil with a 4-pct fuel content is about 200C. The presence of water in lubricating oil is briefly discussed. In railway practice only traces of water (0.05%) are permitted. According to LIVT a water content of 0.4 pct can be admitted in oils used for marine power plants. The lubricating oil can be tested for water by using magnesium sulphate.
