This thesis presents a way to estimate the time optimal economic replacement of a diésel engine using the historical data of oil analysis in a model of residual life time, with the objective of reducing catastrophic failures and maintenance costs. The model studied will depend on two random variables: the measurement of wear metals (iron) and the average time of duration of engines, for the description and analysis of these variables the distribution of probability of Weibull will be used with some personalized variations. The estimation of the parameters of the Weibull distribution will be made with the maximum likelihood estimation method (MLE) and programming algorithms will be used. The model will be applied to a diésel engine brand Cummins model K2000E, which is used in mining trucks KOMATSU 730E, which work in a mining operation at a height between 3,400 and 4,200 meters above mean sea level (mamsl). The results of the model that were simulated separately to two engines are shown, one changed by failure and the other changed preventively, the difference of both cases is analyzed and described. The importance of this thesis is that it can be applied to different diésel engines for which oil analysis information is available. The presentation of the results and conclusions will be in graphic form.
