Keywords: reciprocating engine, piston, jet cooling, mathematical model. The authors carried out numerical simulation of hydrodynamics and heat exchange in jet-cooled pistons under varying load conditions. The results are supported by experimental data. Areas of further studies are discussed.1 table, 8 ill., 5 ref.
Keywords: mixture formation, fuel injection and combustion, fuel efficiency, pollutant emission. The article discusses ways to improve combustion in series T engines with direct injection and open type combustion chamber, in order to enhance fuel efficiency and reduce noxious emissions.1 table, 5 ill., 3 ref.

Keywords: turbocharger, two-stage supercharge system, reduction of pollutant emission, Miller cycle. Today engine builders looks for ways to reduce pollutant emission without compromising fuel efficiency. ABB Turbocharging modelled NOx emission of diesel engine featuring Miller cycle, two-stage supercharge system and controllable valve timing.2 table, 13 ill., 6 ref.
Keywords: fuel, magnetic inspection, ferrous admixtures bar charts. The authors compared known methods of testing fuels for contents of ferrous admixtures. With multioperation magnetic inspection method bar charts were derived, descriptive of ferrous admixtures distribution in petrol by particle size, volume and surface area.- table, 6 ill., 30 ref.
Keywords: diesel engine, rapeseed oil, mixed fuel, stand tests. The article discusses comparative tests of tractor engine firing diesel fuel and its mixtures with rapeseed oil. Engine performance in principal operation modes was studied.- table, 4 ill., 8 ref.
Keywords: marine diesel engines, components, functional reliability, mathematical models. The authors consider forecasting methods of functional reliability of marine engine components based on assessed failure rate. Models based on closed cubic spline approximation are shown to be the most adequate of all.- table, 4 ill., 8 ref.
Keywords: reciprocating engines, noxious emissions, resource-saving, fuel cells. The review covers some news concerning engine building and alternative energy sources as presented in international trade magazines.- table, 8 ill., - ref.
