Synopsis of published articlesNew approaches to the numerical modelling of stressedand deformed state of engines high-loaded details, processedby the method of discrete strengthening are offered. Parametricalmodel for research of different factors influence onstrength and rigidity in the conjugation of discretely strengthenedinternal combustion engines details is described. Theresults are obtained and generalized on the basis of which theparameters of discreteness are recommended for details processing.Il. 10. Bibliogr. 12 names.UDC 521.4-2Kaukarov A.K. Investigation the dry compaction of internalcombustion engine / A.K. Kaukarov, T.M. Mendebaev.,V.G. Nekrasov, M.K, Kuanyshev // Internal combustionengines. – 2010. – № 2. – P. 123-127.It was investigate of the piston’s compaction in the cylinderwithout use of lubricant oil. The design compressionrings consisting of two rings placed in one groove of thepiston was developed. Each rings is executed with two halfrings and step contact of half in a vertical plane and springsfor their pressing to a mirror of the cylinder. Joints of ringsare shifted be relative each other on 90 degree. The cylindricalsurface of rings has turn in which the antifriction layerfrom hardening paste is incorporated on the basis of graphite.The structure of paste containing 75 % of a graphite powderand 25 % of binding liquid glass was picked up. Paste ischecked up on durability in a separate kind, and also in rings.Thermal stability of paste is tested by temper. The effort toshift the rings in the cylinder and compression in the engineis determined. Wear of rings was studied at their work in theexperimental engine. Positive parameters of dry condensationare received. Table. 5. Il. 5. Bibliogr. 7 names.UDC 621.891Solovyov S.N. To landings’ destination and gap junctionsbetween cylinder and piston in hermetic compressors /S.N. Solovyov, S.J. Bodu // Internal combustion engines. –2010. – № 2. – P. 127-129.The adequacy of the theoretical relations used in theappointment of variables cylinder gaps is consider. The comparisonof calculated and experimental values of parametersin conjugation under extreme temperature conditions is explored,the influence of size characteristics on the reliabilityparameters of friction surfaces, including changes in housingdue to thermal strains is investigated. Tests of the compressorwere carried out on various modes of operation of air conditioning,each mode was accomplished by the diagnostic incoupling. Studies have shown the reliability of theoreticalrelations used in the appointment of tolerances and clearancescylinder coupling. Observed during testing and operationof cases grasped of prehension are due to launch wear.Table. 3. Bibliogr. 9 names.UDС 621.436: 621.74Taran S.B. Real prospects in implementation of pig-ironwith vermicular graphite for pistons of high-forced diesel/ S.B. Taran, O.V. Akimov, A.P. Marchenko // Internalcombustion engines. – 2010. – № 2. – P. 129-132.An analysis of pistons’ work environment of the highforceddiesel combustion engines is brought. The results ofpistons’ constructions from cast-iron with a vermiculargraphite developments and perspective of expansion of design-engineeringworks with the purpose of further decline oftheir mass are reported.

The technique for measurement thedeformations of details in the cylinders-piston group, basedon esistive-strain sensor is developed. Values of plugs’ deformationsin cylinders during diesel engine assembling arecertain. The factors influencing deviations of macrogeometryof cylinders at assembly are shown. Il. 3.

Gulay // Internal combustion engines. –2010. – № 2. – P. 137-140.The receipt of information on diagnostic parametersgives the clear picture of the technical state of diesels. If toconduct systematization of diagnostic parameters, more preciselythan methods of receipt of information about the technicalstate of diesels it is possible to get the level systemwhich allows with a high probability to diagnose to the exploiteddiesels. In work 5 levels of receipt of informationabout the technical state of diesels with forward stage clarificationare offered, which theoretical research of dependencesof probability of faultless work from diagnostic parametersand their weight is conducted on the basis of. Graphic interpretationof realization of theoretical dependences of probabilityof faultless work of diesels is thus presented at theproper level, diagnostic parameters and their coefficients ofweight from the explored time domain. The conducted experimentalresearches of change of diagnostic parametersdepending on time showed adequacy to the theoretical hypotheses.Il. 2. Bibliogr. 9 names.UDC 621.43.068Bgantsev V.N.
