	The influence of operational factors on the wear process of the truck engine parts was analysed. Discontinuity of engine operation was found to be a crucial factor. Contribution of start-ups, following breaks in operation in total wear of the engine is significant and in case of investigated engine amounts 40%. As wear of engine parts accompanying a single start-up strongly depends on the temperature, cold start-ups (usually first in the morning) are of particular importance. Taking above into consideration the authors suggest modelling the course of wear as a stochastic process with the following constituents: - transmission process with linear realization representing average value of wear, - stationary process with periodical realization representing deviations of wear intensity in particular seasons accompanying cold start-ups, - stationary process of statistic fluctuations with random time realizations, representing instantaneous deviations of wear in relation to average values. Mathematical model was illustrated with some empirical results.
