The laws that govern the durability of crankshaft-piston assembly friction nodes can be proved or at least derived or justified in an intuitive way. Operation of all the friction nodes is disturbed by external factors occurring with randomly changing intensity and also appearing at random. As the crankshaft-piston assembly friction nodes have a series structure and effects of those disturbances accumulate, their fitness for use period can be presented as an image of appearing disturbances with determined effects. This can be done on the probability distribution basis. The crankshaft-piston assembly usual wear and tear process is long, therefore images of the appearing disturbances should be characterised by the degree of wear, i.e. the change of the friction node durability, which is a subject of the Markov chain process. The friction node surface durability is an effect of many factors (e.g. stress pattern in the contact area, the surface material hardness, chemical properties of the surface material etc.). However, among those mentioned the least known effect is that of the properties of lubricating agent on the fatigue strength of friction node elements in the crankshaft-piston assemblies. Therefore, the paper presents a reliability model allowing to estimate the fatigue wear of friction nodes in the crankshaft-piston assembly, operating in a lubrication contact with different loads, temperatures and speeds.
