New Generation of Kolomna Diesel Engines
// Dvigatelestroyeniye. 2009. 2. P. 1820.
Keywords: locomotive engines, performance standards, pollutant emission, advanced developments, Miller cycle, split supercharge system.

In terms of performance, including emissions, commercially available locomotive diesel engines type 126DT-01 (3rd generation) meet highest international standards, and outperform many world analogs.They have been granted TUF NORD certificate. Based on R & D works, the company set about designing of new engine family D500 (12CHN26,5/31) rated at up to 7360 kW. New engine features combustion process based on Miller cycle and split supercharge system, with mean effective pressure of 27 bar and maximum combustion pressure of 220 bar.

Hierarchical Model System to Facilitate Evaluation of Engine Parts' Strength
// Dvigatelestroyeniye. 2009. 2. P. 2127.
Keywords: locomotive engines, strength safety margins, strain & stress analysis, experimental research.

The article details possible causes of power loss and part failures in diesel engine due to long-term exposure to various combinations of static and dynamic loads. Hierarchical strength analysis model system is offered, taking account of part material and work conditions. Analysis results and safety margin values need to be verified with tests at dedicated test stands.

Running balance of 10-cylinder engines
// Dvigatelestroyeniye. 2009. 2. P. 2830.
Keywords: ten-cylinder engines, crankgear configuration, balance analyses.

The article discusses issues of running balance in 10-cylinder V-engines. The task in question turns out pretty sophisticated due to multiplicity of layouts with varying vee angles and crank throws' angular arrangement. It is solved through use of generalized crankgear layouts. The solution yields expressions for vertical and horizontal unbalanced moments of inertial forces associated with rotating and reciprocating masses; these may be used in engine vibration analyses and counterbalancing calculations. Said method is equally applicable in counterbalancing calculations for other crankgear configurations.

Engine with Transparent Windows in a Cylinder Liner as a Means to Examine 3-D Mixing Processes
// Dvigatelestroyeniye. 2009. 2. P. 3134.
Keywords: Air-fuel mixing, combustion chamber, fuel combustion.

The result are presented of investigation into 3-D air-fuel mixing in the engine with transparent cylinder liner windows. Based on said investigation, some new advanced combustion chamber configurations were developed differing in 3-D air-fuel mixing arrangement.
