SYNOPSIS

ENGINE BUILDING IN RUSSIA
UDC 621.43

Road Map for the Development of Reciprocating Engines in Russia up to Year 2020 (continued)
// Dvigatelestroyeniye. 2016. 2. P. 318.
Keywords: reciprocating engine, engine building trends in Russia, import replacement, engine building strategies, development of dedicated industrial facilities for engine component production.

The analysis is carried out of today engine building trends in Russia and future perspectives of the branch. Domestic engine building is shown as gradually losing modern technologies, competences and competitiveness. The paper offers a roadmap for improvement in Russian make reciprocating engines targeted at their higher competitiveness.

Pistoncylinder Tribounit in High-Powered Diesel Engine: Experimental Evaluation of Friction & Wear Parameters
// Dvigatelestroyeniye. 2016. 2. P. 1923.
Keywords: reciprocating engine, pistoncylinder tribounit, friction modes, test cycles, friction unit wear intensity.

Tribometer type SRV (based on reciprocating movement of reference gauges) was used to test pistoncylinder tribounit made of various materials. Conditions for boundary and mixed friction modes have been studied as applied to high-powered engine type CHN 13/15. The tests yielded wear intensity vs. contact pressure curve, which largely defines tribounit service life.

Indicator Diagram as a Means of Evaluation of Piston Rings' Tightness
// Dvigatelestroyeniye. 2016. 2. P. 3640.
Keywords: piston ring diagnostics, piston ring wear, cylinder liner wear, seal throttling characteristic, indicator diagram.

The technology in question allows evaluation of a leak through the gap between piston rings and cylinder liner walls based on the analysis of indicator diagram with no fuel injected. Seal throttling characteristic are plotted for the gap between piston rings and cylinder liner walls of marine diesel engine. The technology enables accurate in-situ evaluation of piston-cylinder gap tightness.

Development of Hyundai Heavy Industries Engine Lines-Up (Papers of CIMAC-2013)
// Dvigatelestroyeniye. 2016. 2. P. 4154.
Keywords: HHI, engine line-up concept, high-speed engines 17/28, medium-speed engines 46/60, design features, engine data.

One of the world's largest engine makers, Hyundai Heavy Industries (HHI) has been developing new high-speed (17/28) and medium-speed (H46/60V) engine families. The below papers present design concepts of HiMSEN engine families, such as modular approach, optimization with respect to fuel consumption, emissions, operating costs, service life, and easy maintenance. The CIMAC papers are translated into Russian by G.Melnik, PhD.
