Some patterns of marine diesel engines circulating oil contamination process
Operation of the complex "diesel - lubricating system - circulating oil - separator" is considered and its influence on the process of changing the operational parameters of the oil. It’s shown through the dynamics of the accumulation of mechanical impurities in the oil when engine is running. The role of the oil purificator in the overall balance of insoluble contaminants in the circulating oil of a marine diesel engine is revealed. The presence of the optimum capacity of the centrifugal separator in the engine lubrication system is shown, at which the level of accumulation of mechanical impurities in the oil is at a minimum level. Kinetic equations for lubricating oil aging in marine diesel engine are given under the condition of operation without topping up. The calculations can be used to determine oil lifetime before its replacement.
