Abstract
A kinetic model of the processes of chain oxidative reactions in automotive catalytic converters and PM2.5 soot particle filters of a honeycomb block design has been developed. Calculations according to the model confirmed the emergency modes of operation of converters, uncontrolled heat growth of more than 261683 kJ/h and, as a consequence, the oxidation temperatures of CO, CH, soot with melting and destruction of catalyst carrier matrices. It is shown that the causes of extreme neutralization modes can be malfunctions of electronic catalytic systems, increased sulfur content in fuel and oil, corrosion of fuel equipment parts, overheating of the engine and turbocharger. It is shown that the emergency heating of the converter is associated with an increase in the risk of car fire. An original method for monitoring the environmental-fire hazardous modes of operation of catalytic converters based on the modernization of the standard diagnostic procedure in accordance with GOST 33997-2016 (TR TS 018/2011) is proposed.
