Article is devoted to settlement pilot studies of air-gas system of the diesel locomotive improved by a cyclone-electrofilter. The main attention is paid to determination of the overall performance, the developed air-gas system. The mathematical model of gasdynamic processes of air-gas system which allows to estimate influence of a geometrical configuration and electro-dynamic impacts on process of purification of the fulfilled gases from firm soot is constructed. Comparison of the obtained settlement data with experimental is carried out.
