Abstract

The article presents the theoretical analysis of the possibility of using spiral-elliptical ducts in the atomizer of a modern fuel injector. The parameters of the injected fuel stream can be divided into quantitative and qualitative. Quantitative is the amount of injection dose, and qualitative is characterized by the stream of injected fuel (width, atomization, opening angle and range).The purpose of the atomizer modification is to cause additional flow turbulence, which may affect the stream parameters, which may improve the combustion process of the combustible mixture in the diesel engine. The spiral-elliptical ducts made can be used in engines powered by vegetable fuels. The stream of such fuels has worse quality parameters than conventional ones due to their higher viscosity and density. The proposal to use spiral-elliptical ducts is an innovative idea and can be used in diesel engines.
