Створення на базі мікротунеля універсальної системи екологічного діагностування транспортних двигунів і котелень

Abstract

A description is given of an experimental sample of a universal system for the environmental diagnosis of transport engines and boiler plants, developed by specialists from O.M. Beketov National University of Urban Economy in Kharkiv and the National Technical University "Kharkiv Polytechnic Institute". The distinctive features of this system are noted: universality, multifunctionality, compactness, mobility, ease of operation, high degree of automation and information content of the results provided, possibility of use in research and educational fields. The following are examined: the structure, composition and functionality of the main modules of this system: 1) a measuring device, which includes a sampling device - MKT-2 microtunnel, instruments and equipment for direct monitoring of indicators of chemical and physical pollution of the environment; 2) testing and demonstration, consisting of a stand-alone installation for the study of aerodynamic processes in the exhaust systems of engines and chimneys of boilers, a transformer laboratory rack for mounting various test benches, a multimedia complex equipped with a tablet PC and a 43" diagonal information panel for demonstration operation of instruments, equipment, application programs, research results, etc.; 3) laboratory, consisting of instruments and equipment for laboratory analysis of samples, from collected in the course of environmental studies of natural objects. Systematic methods and techniques to determine and analyze indicators characterizing chemical and physical pollution of the environment by transport engines and boiler plants. The results of experimental testing of the measuring system at full-scale objects: gasoline engine of a car - VAZ-21081 , automotive diesel engine - 4ЧН12/14, gas boilers - ДКВР-20/13, AOGV-100E, solid fuel boiler - КЧ-М-2М-4. Tests have confirmed the practical suitability of the created measuring system
