   <abstract xml:lang="ru">
    <p>Рассматривается вопрос физико-математического представления термической динамики (кинетики) процесса конверсии отработавших газов в каталитическом нейтрализаторе на опасных с точки зрения возгорания, неуправляемых аварийных режимах его работы в эксплуатации. К современным автомобильным двигателям предъявляется требование обеспечения пожарной безопасности. На двигателях с нейтрализаторами оно вступает в противоречие с жесткими международными экологическими стандартами, соблюдение которых принуждает опасно разогреваемый нейтрализатор размещать в моторном отсеке рядом с легковоспламеняющимися горючими материалами. Проблемный вопрос предлагается решать путем контроля и диагностирования пожарно-аварийных режимов эксплуатации нейтрализаторов безразборным способом, научно обоснованным на междисциплинарной основе, – по анализу состава отработавших газов. Метод положительно протестирован&#13;
в условиях реальной эксплуатации.</p>

    <p>The issue of physical and mathematical representation of the thermal dynamics (kinetics) of the process of conversion of exhaust gases in a catalytic converter in dangerous, from the point of view of fire, uncontrolled emergency operating modes of its operation&#13;
is considered. Modern automobile engines are required to ensure fire safety. On engines with converters, this conflicts with stringent international environmental standards, the satisfaction of which requires the dangerously heated converter to be placed in the engine compartment next to flammable combustible materials. It is proposed to solve the problematic issue by monitoring and diagnosing fire and emergency operating conditions of neutralizers in an in-place method, scientifically substantiated on an interdisciplinary basis – by analyzing the composition of the exhaust gases. The method has been positively tested under real operating conditions.</p>
