Pushka O. The improvement of fuel efficiency and the reduction of exhaust opacity of turbo-charged diesel engines

The object of research is the process of automatic control of additional air supply into cylinders of turbo-charged diesel engines. The purpose of work is the improvement of fuel efficiency indices and the reduction of diminishing of exhaust gases opacity due to the additional air supply in to the diesel cylinders. Methods: analytical methods of mathematical design of intermediate regime of work of diesel at the application of the system of automatic control of additional air supply of the size of optical closeness of exhaust gases; numerical methods of decision of the system of differential equation of the functional elements of diesel at different regimes of work; methods of planning and constructing of the electronic systems of automatic control and facilities of diagnostics; methods of engineless and engine researches of diesel with the experimental system of automatic control of additional air supply. The rational method of additional air supply into turbo-charged diesel engines in the intermediate regimes of work is grounded. The mathematical model of the intermediate regime of work of diesel 6ЧН13/11,5 with the experimental system of automatic control of additional air supply into cylinders is specified. Dependences of a calculation of additional air supply in to diesel cylinders are obtained, which allowed to provide the rational choice of parameters of air supply taking into account the expenses of fuel and exhaust opacity. A sphere of the application is the enterprises which are engaged in making and repairing the systems of air supply and fuel supply of diesels and the educational process.
