The Initial Estimate of the Useful Lifetime of the Oil in Diesel Engines Using Oil Analysis

摘要

In this paper the Initial lifetime of the lubricating oil in 70 Diesel engines model E6-350 ECONODYNE 4VH has been estimated using oil analysis. The engines have been installed on the super heavy vehicles. This method is used to change the used oil based on oil operating hours, odometer and taking samples before that. Next, the samples are sent to the laboratory for analysis and obtaining the results. In order to be able to determine the overall condition of the engine, we have to study various parameters, such as wear elements, pollutants, elements correlation coefficients, viscosity, base number, acid number, type and the amount of engine wear in the same condition of the engine model, oil consumption and operating condition and therefore, the useful oil life is determined (100 hours). At last, a formula for silicon and aluminum elements is found. If the number of samples increases then the error rate will be reduced. So, the results are only based on the number of taken samples.
