Обгрунтування доцільності використання способу прискореного виміру твердих частинок з відпрацьованими газами тепловозів

Abstract

Has been analyzed the problem of increasing the duration and cost of the regulated procedure for ecological diagnostics of diesel power plants during the measurement of particulate emissions compared with gaseous pollutants: nitrogen oxides, carbon monoxide and hydrocarbons, which appeared with the introduction of a new normalized value – the average operating emission of solid particles with exhaust gases of diesel engines. The accelerated measurement method of mass emissions of particulate matters, which meets the requirements of the international standard ISO 8178 is proposed. Implementation of this method allows to increase the economic efficiency of ecological testing of diesel engines by increasing the rate of filtration of the sample to the maximum allowable value and collecting the minimum permissible mass of particulate matters on the filters. The method of estimation of efficiency of using the proposed method according to the criteria of duration, fuel consumption and cost of tests is developed. The expediency of the use of this method in the course of ecological testing of locomotive diesel engines has been proved experimentally.
