Abstract

The article presents the results of motor tests of mass production filtering elements and new ones with improved performance in marine diesel engines. The filtering elements help to increase the efficiency of cleaning the engine oil and to lessen the engine wear and carbonation. The extended diesel service life is directly connected to the quality of oil purification. There has been carried out the analysis of developing filter technology regarding to engine oil cleaning in lubrication systems of ship medium-speed internal combustion engines equipped with different oil cleaners on the vessels of the Far Eastern basin. There have been presented the methods of increasing the throughput, dirt capacity and service life, as well as the fineness and completeness of sifting filtering elements due to the use of new filter materials. The dependence of the oil filtration rate on the efficiency of its purification is shown. Oil purification process can be intensified by means of decreasing the rate of oil filtering. To obtain the optimal filtering rate it is necessary to choose the appropriate size of a filtering element. Nowadays, the production technology of filtering elements is constantly improving, parameters of filtering materials are being upgraded, such as porosity, specific capacity, etc. There have been proposed measures to improve the hydraulic and filtering characteristics of nonwovens from cellulose and synthetic fibers of different thicknesses with different fillers and binders, which increases the permeability of papers, the number of pores per unit surface and a narrower distribution in diameter. New scientific and technical solutions are presented, which increase the efficiency of oil use in diesel engines. The ways of reducing the wear rate of the main parts in the engine due to full-flow fine cleaning of lubricating oil providing economical resource-saving operation of the trunk diesel engines are shown. The Russian industry manufactures the full-flow filtering elements and filtering materials relevant to the best international analogues.
