Evaluation of Cylinder Head Durability in Medium-Speed Transport Diesel Engine
// Dvigatelestroyeniye. — 2010. — ¹ 2. — P. 3–6.
Keywords: medium-speed diesel engine, cylinder head, material strength criteria.

The article deals with cylinder heads of medium-speed diesel engines. Two marginal states of material strength criteria are considered. One marginal state is characterized by thermal fatigue of material. Another one is caused by alternating-sign plastic deformation in quasi-elastic range. Cylinder head durability is evaluated as applied to locomotive/marine engine type 16CHN26/26.

Evaluation of Fuel Injection Rate Based on Pressure Pulse Profile Downstream of High Pressure Feed Pump
// Dvigatelestroyeniye. — 2010. — ¹ 2. — P. 11–14.
Keywords: low-speed marine engine, fuel injection rate, fuel injection system, diagnostics.

The article discusses test results of fuel injection equipment featured by low-speed marine engine type 6S50MC-C (Russian-built under a license of «MAN Diesel»). Method is offered for evaluation of fuel injection rate based on pressure pulse profile downstream of high pressure feed pump. Integral and differential characteristics of fuel injection process are derived to be used in diagnostics of marine engine fuel injection equipment.

Gas-impulsive Treatment of Constructional Materials Without Pre-Heating
// Dvigatelestroyeniye. — 2010. — ¹ 2. — P. 20–22.
Keywords: constructional materials, gas-flow hardening, stress condition.

The investigation in question was dedicated to effects of subsonic gas flows on properties of metal exposed to unsteady gas jet (with no pre-heating). Gas-impulsive treatment is demonstrated as decreasing residual stress in thin-walled titanium alloy pipes.

Dependence of Piston–Cylinder Tribounit Hydromechanical Characteristics on Oil Viscosity vs. Temperature Curve
// Dvigatelestroyeniye. — 2010. — ¹ 2. — P. 23–26.
Keywords: diesel engine, lube oil, piston design, piston/cylinder tribounit.

Piston–cylinder tribounit of type CHN13/15 engine was analyzed and tested with a variety of commercial lube oils differing in rheological properties. Hydromechanical characteristics of piston/cylinder tribounit are demonstrated as improvable without any constructional changes. Methods are offered to lower lube oil consumption based on solution of optimization problem.

Disabling of a Part of Cylinders Improves Fuel Efficiency Of kamaz 740.10 Engine
// Dvigatelestroyeniye. — 2010. — ¹ 2. — P. 34–36.
Keywords: marine diesel engines, failure statistics, fuel delivery system, functional reliability.

A peer review has been carried out of engine reliability as a function of availability of its systems' components, based on failure statistics. Marine engine reliability is shown as primarily determined by fuel system failures. Failure data are presented in the form of infallibility and repairability factors, as well as integrated reliability indicators.
