Keywords: reciprocating engines, marine, locomotive and industrial engines, autarkiation, engine building development strategy, dedicated industrial facilities for engine component production.

The draft strategy for engine building development has been prepared based on the results of Subprogram «Development and Organization of Domestic Production of New Generation Diesel Engines and Their Components in the Period of 2011–2015» (a part of Federal Program «National Production Basis»). Lack of dedicated industrial facilities for engine component production was identified as a key constraint in implementation of said Federal Program.

Keywords: reciprocating engines, casing parts, cylinder heads, threaded connections, input model.

The authors investigated various ways of threaded connection presentation in modelling cylinder head assembly with cylinder block/liner. The task of threaded connections' simulation was solved for axisymmetric and 3D statement.

Keywords: internal combustion engine, valve timing, valve phasing mechanism, electro-hydraulic drive, electronic control system, solenoids, control algorithm.

Newly-developed electro-hydraulic drive for engine valve phasing mechanism is described. The article describes the details of solenoid control system and control algorithm. The test result are discussed.

Keywords: diesel engine, cylinder head, aerodynamic test stand, gas ducts, flow characteristic, flow whirling.

The aerodynamic test stand was used for characterization of gas ducts and valve/seat annular gap of Fiat engine Multijet (displacement 1.3 l). It is shown that flow characteristics of the gas ducts may be improved and flow whirling enhanced through optimizing duct profiles and valve/seat geometry respectively.

Keywords: diesel engines, gas engines, mean effective pressure.

Review and analysis of reciprocating engine development for 40-year period, with a focus on progress in mean effective pressure and piston speed. The increase rate of the above parameters is shown to decelerate lately, since reaching tradeoff between engine fuel efficiency and environmental performance becomes growingly problematic.

Keywords: diesel-generator sets, provide beyond assigned resource, deterioration assessment, potential damage, critical failures.

A method is offered to identify non-conformity criteria for diesel-generator sets powering military facilities, based on integral evaluation of their deterioration criticality. It is probable damage that seems to be the best candidate for such an integral criterion. It may be evaluated through analysis of critical failure consequences.

Keywords: marine diesel engine, power plant, assigned resource, run hours, assigned resource, operation beyond original design life, failure risks.

A number of marine diesel engines with design life close to expiration were analysed for performance. Engines are shown to be able to remain in operation beyond their original design lives under certain conditions. Cases of running engines beyond their design life are considered, and risks of probable failures are appreciated.

Keywords: imported diesel engines, spare parts, thermo-softening deformation, «hollow cylinder» type parts, reworking to original dimensions.

The technology is described that enables rebuilding of «hollow cylinder» type spare parts of imported engines with thermo-softening deformation (TSD). A set of tools is developed for rebuilding surfaces of cylinder liners (inner) and piston pins (outer). TSD may be considered as an alternative to procurement of spare parts for imported diesel engines (on-road, marine and locomotive).

Keywords: combustion process, pilot fuel injection, noxious emission level, fuel efficiency.

The work in question deals with partially premixed combustion (PPC) for low load conditions in a marine engine using computational and experimental technique. Said technology allows to reduce engine noxious emission level through controllable ignition delay and better air-fuel mixing. The experiments have been carried out on a single-cylinder engine EVE installed in at Aalto University, Internal Combustion Engine Laboratory. Such parameters as injection timing, injection period, injection pressure, inclusion angle of the spray have been investigated as key factors that influence the combustion process in PPC mode.
