JSC ZVEZDA Celebrates the 85th Anniversary
// Dvigatelestroyeniye. 2017. 1. P. 39.
Keywords: JSC ZVEZDA, high-speed multi-purpose diesel engines, reverse reduction marine transmission, new gear production facility.

JSC ZVEZDA is leading Russian designer / producer of high-speed multi-purpose diesel engines rated at 500 to 7400 kW for marine, railway and portable power plant applications. As a part of import-substitution program the Company branched out into making heavy-duty reverse reduction marine transmissions rated at up 40 000 kW for RF Navy and passenger ships. In March 2017 new reverse-gear production facility has been put into operation.

Anent the 110th Anniversary of Introduction of Reciprocation Engines Course in Bauman Moscow State University
// Dvigatelestroyeniye. 2017. 1. P. 1315.
Keywords: Bauman Moscow State University, Reciprocation Engine Department, development of modern engines, education, development of CAD components.

Cooperation between Reciprocation Engine Department of Bauman Moscow State University and PJSC Kolomensky Zavod has been lasting for many decades. The cooperation concerns the development of modern state-of-the-art engines and training of personnel to be employed by PJSC Kolomensky Zavod. Kolomensky Zavod researchers, engineers and technicians extensively use CAD components developed by Reciprocation Engine Department of Bauman Moscow State University.

Research Activities of Reciprocation Engine Department for the Last Five Year Period
// Dvigatelestroyeniye. 2017. 1. P. 1623.
Keywords: reciprocation engines, development of training disciplines, optimization of combustion, fuel injection system, improvement of emission performance, modelling of non-steady flows and heat exchange, design and stress-strain analysis of engine components.

The authors present review of the development of core disciplines in the area of modern reciprocation engines, worked out by Reciprocation Engine Department for the last five year period. Presented are the results of research programs concerning optimization of combustion systems, improvements in fuel injection systems, lowering of noxious emissions, modelling of non-steady flows and heat exchange in engine components, construction and strength analysis through simulation stress-strain analysis of engine parts subject to thermal and mechanical loads.

Development of Two-Stage Supercharge Systems
// Dvigatelestroyeniye. 2017. 1. P. 2430.
Keywords: diesel engine, gas engine, two-stage supercharge system, pressure ratio, Miller cycle, knock, supercharge in lean combustion engine, emission legislation, fuel economy.

The article presents review and analysis of today trends in two-stage supercharge systems (TSSS) of two- and four-stroke engines used in various applications. TSSS for two- and four-stroke engines differ in configuration and efficiency in terms of expected improvement in engine operating parameters and emission performance. As far as four-stroke engines featuring Miller process are concerned, NOx emissions are lowered by 40 %, while in two-stroke engines TSSS implementation results in fuel consumption lowering by 25 g/kWh.

Determining of Compression Dispersion in Engine Cylinders by Cranking Method
// Dvigatelestroyeniye. 2017. 1. P. 3133.
Keywords: reciprocation engine, piston-cylinder unit, cranking, dispersion of electric starter peak currents, dispersion of compression.

A diagnostic method for engine piston-cylinder unit is offered, based on difference in starter peak currents during cold cranking. The idea of the method boils down to determining the difference between starter peak currents corresponding to TDC positions of each individual piston. Mathematical relations are offered that enable determination of compression dispersion in engine cylinders.

Research in and Improvement of Combustion Systems (based on CIMAC 2016 papers)
// Dvigatelestroyeniye. 2017. 1. P. 3458.
Keywords: gas engine, pre-chamber ignition system, visual study of combustion process, lean-burn gas mixture, alternative zero-sulfur fuels, test engine with quartz windows, shadowgraph.

Specialists of FEV GmbH and Aachen University used single-cylinder research engine for examination of pre-chamber system of fuel gas ignition (including lean mixture). Engine parameter were optimized by use of simulation-based design method called CMD (Charge Motion Design). The international team of experts examined combustion of a number of liquid and gaseous zero-sulfur fuels using visualization. Tested fuels are intended for large marine engines. Experimental apparatus is basically a single-cylinder test engine that has been completely modified and converted into RCEM (Rapid Compression & Expansion Machine), equipped with conventional high-speed cameras and shadowgraphs. The work resulted in practical recommendations on optimal choice and usage of alternative fuels for typical engine applications. The CIMAC papers are translated into Russian by G.Melnik, PhD.
