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.

Keywords: reciprocating engine, piston–cylinder tribounit, friction modes, test cycles, friction unit wear intensity.

Tribometer type SRV (based on reciprocating movement of reference gauges) was used to test piston–cylinder tribounit made of various materials. Conditions for boundary and mixed friction modes have been studied as applied to high-powered engine type CHN ЧН13/15. The tests yielded «wear intensity vs. contact pressure» curve, which largely defines tribounit service life.

Keywords: spark ignition engine, volumetric combustion technologies HCCI & GDCI, fuel autoignition conditions, ignition control, homogenization of fuel/air mixture.

Discussed are the technologies of fuel/air mixture homogenization and volumetric combustion control in engine cylinder. Ignition control technologies HCCI & GDCI are compared in terms of their respective strengths and weaknesses.

Keywords: cooling system, cooling pump, electric drive, switched reluctance motor, SRM.

Cooling systems featuring engine-driven pumps are shown as having a number of drawbacks. Advantages of SRM-driven pumps are demonstrated. Specifically, such pumps are able to secure optimum engine thermal conditions.

Keywords: reciprocating engine, benchmark test, dynamometer, test bed, test cycle, test schedule.

The article discusses design issues of automated dynamometers for engine test beds. Various dynamometers are compared in terms of power efficiency. Typical test system structures and engine test schedules are presented.

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.

Keywords: HHI, engine line-up concept, high-speed engines Н17/28, medium-speed engines М46/60, design features, engine data.

One of the world's largest engine makers, Hyundai Heavy Industries (HHI) has been developing new high-speed (Н17/28) 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.
