This article presents statistical data on the reliability of diesel engine cylinder liners. Besides, discussed is the methods of determining the boundarey conditions that may occur at tension-deformed states of Diesel cylinder liners. The influence of design features and operating regime of a Diesel engine on thermal stress of the cylinder liner is shown.

The present article is devoted to the results of calculation of ZD72/48 type (of different models - with and without undercut) engine atomizers in tense-deformed condition by the finite elements method. Besides, the article deals with the influence of heat and mechanical loads and design features on the atomizer body deformation for that type of engine.

This case study, involving a ship of the STRM type, has shown that increased vibrations in crew accommodations to a large extent depend on stresses exerted by the screw propeller. It has been found that the frequency of propeller blades and its second harmonic have the largest effect on ship hull. The amplitudes of the first and fourth order stresses were calculated.
