Selection and Evaluation of High-Speed Marine Engine Configuration
// Dvigatelestroyeniye. 2014. 4. P. 1015.
Keywords: high-speed marine engine, performance criterion, Harrington function, mathematical modeling, prospective engine cylinder dimensions.

The method in question enables marine engine shaping at early design stage based on integral performance criterion making use of Harrington function. The work included mathematical modeling of high-speed marine engine rated at 140 kW in several alternative versions. Integral performance criterion has been applied to three design versions in order to select the most promising engine cylinder dimensions.

Turbocharging System Optimization as a Means to Improve Engine Fuel Efficiency
// Dvigatelestroyeniye. 2014. 4. P. 1928.
Keywords: internal combustion engine, turbo-compound systems, power and steam turbines, hybrid turbochargers, high-speed generators.

The article offers survey and analysis of various turbo-compound systems that encompass power and steam turbines, hydraulic motors and hybrid turbochargers coupled with high-speed generators. It is shown that, in terms of efficiency, use of various turbo-compound systems is equivalent to increase in power or decrease in fuel consumption by 3 to 10%.

Improvement of Low-Speed Diesel Engine Transient Characteristics
// Dvigatelestroyeniye. 2014. 4. P. 2932.
Keywords: Low-speed engine, transient, acceleration under load, turbocharger rotor boost.

The article discusses a system of turbocharger rotor boost with compressed air, designed to improve engine transient characteristics during start and acceleration under load. Experiments demonstrated that low-speed engine featuring turbocharger rotor boost system may be used (in conjunction with alternator) as NPP emergency power supply.

Development of Fuel Injection Systems for Diesel Engines (based on CIMAC 2013 papers)
// Dvigatelestroyeniye. 2014. 4. P. 4657.
Keywords: marine engines, fuel injection equipment, mechanical systems, common rail systems, hardware and software, L'Orange, Bosch.

One of the papers referred presents L'Orange fuel injection systems for Asian and Chinese markets. In addition to the significant further development of traditional mechanical fuel injection systems, which experience a continuing qualification for future tasks and a renaissance for large-bore engines, this paper describes in detail the development of two custom-made Common Rail fuel injection systems. Another presentation describes the Bosch electronic diesel control system for medium and high speed engines. Presented are principal features of R.Bosch EDC17CV41 controller hard- and software adapted to marine engine applications. The CAN-compatible controller, sensors and actuators may be seamlessly integrated into an upper-level ship automation system. The papers were translated into Russian by G.Melnik, PhD.
