Technologies for diagnosing the mechanisms of diesel internal combustion engines (ICE)

Modern methods of diagnosing diesel internal combustion engines are not sufficiently informative and expensive, and the range of diagnostic tools for the technical condition of diesel engines is limited, there are no universal mobile diagnostic systems. Therefore, the internal combustion engines get into repair with an underused resource, at the same time, the timely adjustment would avoid costly repairs and increase the turnaround time. Thus, the development of effective, mobile means of diagnosing the crank mechanism and the piston-cylinder group is relevant. The objective of the study is to reduce operating costs over the entire service life of the internal combustion engine. To do this, it is necessary to solve the following tasks: based on a technical and economic criterion, develop the optimal structure of the maintenance and repair cycle, develop an algorithm for diagnosing and a complex of works for current repairs, determine the frequency of diagnosis and the complexity of work. Field of application- motor transport companies; enterprises operating motor-and-tractor equipment; service stations; bases of centralized maintenance of automotive equipment.

Technologies for creating units and mechanisms that do not require maintenance during the period between major overhauls

In the Russian Federation, a limited number of enterprises are engaged in the development and production of bearing units operating in the high-temperature zone with a high rotational speed. The products are used in turbines of internal combustion engines (ICE) and other high-speed technical equipment. At RUDN there are developments of bearing units differing in the ability to work in the zone of high temperatures and high rotational speed. The goal is to develop methods for designing bearing units. The project is aimed at solving research problems involving the experimental evolution of bearings in pilot units, as well as conducting a series of field tests as part of operating turbomachines. Field of application- machine-building enterprises of the rocket and aerospace industry.

Perspective devices and materials for micro- and nanoelectronics

New research and development, allowing to create devices with picture orientation molecular microstructure, 2- and 3-dimensional permanent polarization-optical, nano-, micro and macro-electron-optical devices. Research is aimed at obtaining materials and methods that will allow preserving the advantages of liquid crystals, to maintain the recorded information during operation despite the mechanical deformation of the device.
