    Experimental Investigations on Operational Reliability of Diesel Locomotyves Engines
    (Polish Maintenance Society (Warsaw), 2012) Lingaitis, Leonas Povilas; Myamlin, Serhiy V.; Baranovsky, Denis М.; Jastremskas, Virgilijus
    EN: In work experimental researches of longevity and technical and operating parameters of diesel engine diesels are presented 10D100 with modified tribosystems. The last are instrumental in the rapid starting and decline of wear depending on time of starting, thus, such diesel practically on any speed and loading modes can be exploited without the promoted wear. At the modified shells of cylinders the wear of compression rings does not affect the size of breach of gases in carter. Thus, the modified tribosystems provide maximal longevity and providing of high technical and operating parameters of diesel engine.

    The Issue of Saving Fuel and Energy Resources for Hauling Operations
    (2012) Jastremskas, Virgilijus; Lingaitis, Leonas Povilas; Jevdomacha, Grigorij; Evdomakha, Grigory V.
    EN: Abstract The main provisions of the methods used for optimization of station-to-station travel times taken (according to criteria of minimum consumption of fuel and energy resources for haulage), which are used for train timing, are examined. The methods can be applied for cargo, passenger and suburban train service on electrified and non-electrified sections of railway.

    Prediction Methodology of Durability of Locomotives Diesel Engines
    (Polish Maintenance Society (Warsaw), 2012) Lingaitis, Leonas Povilas; Mjamlin, Sergey; Baranovsky, Denis M.; Jastremskas, Virgilijus
    EN: The article testifies that technical maintenance and repair terms as well as durability can be predicted accordingly to the maintenance parameters of the diesel locomotives. It is determined that fixing fuel consumption and capacity of diesel locomotives and taking in comparison with limit values allows to set a performance date for technical maintenance. Intro - duced suggested aspects of interrepair resource of the diesels dependent on comparable fuel consumption and evaluating their operating probability without failure for the durability prediction of diesel locomotives. Currently, the most common are three strategies: until failure, scheduled – premonitory and adaptive (diagnostic). When the quantity of necessary technical maintenances is known for the specific kind of diesel locomotives it is possible to determine interrepair resource depending on comparative and required per hour consumption of fuel and predict their durability taking into account probability of operating without failures.
