Timchenko D. Improving of fuel economy of high-rotation rate diesels engines by changing conditions of mixing and combustion

Processes of a mixing and combustion in high-revolution four-cycle autotractor injection engines of low power with a direct injection injection of fuel. Definition of directions of martempering of economic parameters of operation high-revolution injection engines with a volumetric - film way of a mixing in cylindrical combustion chamber in the piston. Mathematical and physical simulation of working processes in injection engines at use of mathematical scheduling researches, methods of definition of output parameters of operation, methods of deriving, machining and the analysis of indicator diagrams and oscillograms of parameters of fuel feeder. Ways of increase of efficiency of running cycles in high-revolution autotractor injection engines are defined and justified by change of conditions of processes of a mixing and combustion at the expense of optimization of design parameters and factors which shape them. The technique of a rated estimation of quality of a mixing and combustion is developed on thebasis of the simulation model offered inprocess and a complex of parameters of a mixing and com-bustion. Effect of separate processes and factors which define a mixing and combustion and their total effect on technical-and-economic indexes high-revolution autotractor injection engines is defined. Results of research are introduced in KP "HКBD", re-search laboratory of faculty DVS HNADU. An engine building.
