We should like to report on the methods of removal water contents in diesel engine system oils which we have developed and found suitable for practical application.<BR>In the present report we here explain the working orinciple, results of the preliminary test and performance of the apparatus which is produced as an experiment in proper sequence. The principle is evaporated water contents in heating lubricating oils which are occured cavitation by the higher speed revolution of stirrer. The effect of removal water contents was influenced by temperature of oils, revolution speed of stirrer, ratio of surface diameter and height of oils, shape of stirrer and charging way of cleaning air etc..<BR>It was required the treatment time of the measure of 30 minutes at 65-70°C to regular engine oil and of 60-90 minutes at 100-115°C to heavy duty engine oil.<BR>This technical method may be able to make use of removal water contents in turbine oils and hydraulic fluids etc..<BR>We think that the treatment time is still more possible to shorten for none-additive lubricating oils when the condition of treatment will be choosed aptly.
