Keywords: engine cylinder, microrelief, optimum parameters. New working hypothesis is offered to explain anti-friction effect of engine cylinder microrelief, based on hydrodynamical lubrication theory.- table, 4 ill., 5 ref.
Keywords: two-stroke diesel engines, electronic controls, control algorithms, reliability enhancement. New generation of electronic controls for RT-flex1 series two-stroke engines has been developed. New hardware components relate to fuel injection system and exhaust valve control system. Compared with previous generation, they boast higher reliability and improved control algorithms.- table, 7 ill., 4 ref.
Keywords: diesel engine, fuel injection systems, piezoactuators, dynamic response improvement. The article discusses possible configuration options of advanced injection control systems featuring piezoactuators characterized by low time delay values.- table, 6 ill., 4 ref.
Keywords: diesel engine, turbocharger, improvement of mass and dimensions parameters. Analysis of ABB and MAN turbochargers has been carried out with reference to mass and dimensions parameters. It is shown that noncantilevered layout enables substantial reduction in turbocharger mass and size compared with cantilevered one.1 table, 8 ill., 9 ref.
Keywords: automobile engines, air pollution, forecast scenarios, environmental performance improvement. The results are discussed of long-term prediction of automobile engines' impact on urban atmosphere (by example of Saint-Petersburg).The authors offer four forecast scenarios varying in measures targeted at reducing of бЮ, NOx, бЭ and SO2 emissions.- table, 4 ill., 3 ref.
Keywords: diesel engine, operating parameters, improvement in fuel efficiency, optimum turbocharging parameters. The authors evaluated fuel efficiency of marine engines modernized for heavy fuel operation. Measures were taken to reduce fuel consumption at partial loads which typically account for up to 90% of engine operation time.1 table, 3 ill., 6 ref.
