The procedure of the identification of FE tractor engine model and the results of modelling the cylinder liner misalignment are presented in this paper. The new identification procedure is based on non-contact optical tensometry, which enables the evaluation of a displacement in real time with precision to 0.5 microm. This procedure which utilises electronic speckle interferometry, has several advantages compared to the method of identification using a model with the aid of holographic interferometry used in the previous models, which is time-consuming and technically complicated. The determination of deformation and displacement in a plane of the cylinder liner in the range of 10E-3 - 10E-2 mm, show the increase of stiffness of the engine block of the new ecological tractor engine UR-IV M2 as against the 6-cylinder model UR-IV.
