Samojlenko D. Improvement of the technical and economical factors of autotractor diesel by adjusting turbocharging

The processes of gas dynamics in the cylinder of a diesel engine and flowing parts of turbocharger at turbo-supercharging abjection. Design the new method, perspective constrtuction and recommendations about introduction of adjustable system of a turbocharging of an auto-tractor diesel engine for improvement of its technician - economic indicators. Mathematical modelling of characteristics ICE with turbo-charger. The analysis of indicator diagrammes. A new method of adjustment of a turbocharger by modifying the flow area of the volute acceleration section in turbine’s vaneless distributor is developed. For the first time results of design-experiment research in comparison of efficiency traditional and the offered method of regulation and their influence on technical and economic indices of an autotractor diesel engine are received. Perspective designs of model and pre-production samples of turbochargers which allow to raise essentially technical and economic indices of the autotractor engine are offered. At designing of new adjustable turbines characteristics of a pre-production sample, executed on the basis of serial ТKR – 7TV-03 can be used. Results of scientific research are introduced in Ltd. “Turbo - Vesta” (Kharkov), KP “HKBD” (Kharkov), by problem research laboratory of chair of internal combustion engines NTU“KPI”, and also in educational process during preparation of students of a speciality 090210 - internal combustion engines in NTU“KPI”. An engine building.
