QUALITY AND RELIABILITY OF MARINE DIESEL ENGINES
The quality of engines regulated by the requirements of State standard of the Russian Federation 10.150-88 "Diesels of ship, locomotive and industrial. General specifications" is the quality of diesel production focused on compliance with the requirements of State Standard and provided its high reliability, but not contributed the changed production, trade, economic conditions in the area of operation. These conditions demand from the engine the other quality - operational. Operational quality is characterized by such properties of the engines, by means of which a consumer could develop such quantity of products, which will allow him not to be interested in further condition of the diesel in the case of faults, because he will have an opportunity to buy a new engine; to exchange the exhaust diesel on a new one (with surcharge); to pay major or average repair in the interseasonal period. The question of marine diesel engine reliability is a part of the general theory of reliability of machinery. Marine piston engines as objects of sea equipment and technology, unlike the terrestrial engines (transport and stationary), have the specific features connected with the operational environment. Additional inertial loads due to the pitching of the vessel demand to increase the allowed strength of a number of the elements of the mechanism of the motion transformation. Chemically active operational environment, conducive to corrosion, impact on the reliability of the marine equipment.
