Keywords: Chelyabinsk Tractor Works.

Presented is the history of tank engine development at ChTZ, including legendary V-2 engine. The story is inseparably connected with names of outstanding design managers such as K.F. Chelpan, T.P. Chupakhin, I.Ya. Trashutin, V.I. Gordeev, and design project leader V.I. Butov.

Keywords: Chelyabinsk Tractor Works, engine building.

The article presents main lines and milestones of engine building at ChTZ, including military, civil and dual purpose applications. Highlighted are problems and tasks to be solved by ChTZ and industry sector as a whole, and principal ways of their solution are projected.

Keywords: Chelyabinsk Tractor Works, tank engine.

Presented are milestones of post-war tank engine building at ChTZ. The article illustrates some arrangements of tank engine bays for high-powered engines. Besides, some materials are presented covering tests of tank Т-90С powered by В-92С2 engine in Thar Desert (India).

Keywords: Chelyabinsk Tractor Works, dual purpose engine family.

The article covers the development of new dual purpose engine family at JSC «ChTZ-Uraltrack». The family includes both in-line and V-shaped diesel engines, with high degree of unification. Presented are engine specifications and design features in comparison with similar engines of other world engine builders.

Keywords: GSKB «Tкansdiesel», engine test beds.

The article describes test facilities of JSC GSKB «Tкansdiesel» that comprise several laboratories and feature over 20 dedicated test stands, including engine test beds for R & D works.

Keywords: vehicle engines, fuel spray structure.

Reported are the results of a program targeted at improvement of combustion chamber of type CHN15/18 and CHN15/16 vehicle engines with bigger clearance over the piston, where mixture forms due to structured reflection of uel sprays throughout the combustion space. A method of combustion chamber designing is offered based on modelling of fuel spray structure and its interaction with combustion. chamber surfaces.

Keywords: high-powered engines, piston crown.

Alternating thermal and mechanical loads typical to high-powered engines may result in formation of cracks in piston crown, which in turn would shorten engine lifetime. The author discusses state-of-the-art piston manufacturing technologies resulting in improvement of piston performance.

Keywords: dual-purpose engines, crankshaft.

The article discusses hydromechanical characteristics of crankshaft bearings used in dual-purpose engines type 4Т371.03. Said characteristics were considered vs. counterweight arrangement as engine rated output keeps increasing.

Keywords: combustion process.

Described in this article is improved method of analysis of work medium parameters and their influence on combustion process during engine start period. New equation is offered for calculation of instant in-cylinder pressure that takes account of changes in work medium mass and heat transfer through cylinder walls.

Keywords: engine, heat balance, atomizer.

The influence was scrutinized of said heat balance on engine life. Components of heat balance in contact layer were considered vs. engine load. Boundary conditions were determined for finite element analysis of atomizer thermal status.

Keywords: gas-turbine supercharge, engine emission.

The article presents detailed summaries of CIMAC 2007 papers concerning gas-turbine supercharge and turbochargers, as well as their influence on engine emission performance.

Keywords: low-speed marine engine, fuel injection equipment.

The author presents a method of multivariate statistics and stochastic theory of pattern recognition (STPR) as applied to algorithms of diagnostics of a low-speed marine engine. The article discloses the procedure of the development of algorithm of trouble-shooting in fuel injection equipment based on STPR method.
