ABSTRACT

The article substantiates a comprehensive methodology for increasing the efficiency of oxidative catalysis by using forced electric heating of block catalyst matrices and exhaust gas heat recovery by a phase transition accumulator based on a critical analysis of the load and thermal conditions of a diesel engine of a fire truck in the standby, drive, and water/foam delivery modes. The theory of the original author's methodology is based on fundamental domestic developments in heterogeneous oxidative catalysis and does not contradict advanced foreign practice. The method for increasing the efficiency of catalysis has been tested on fire trucks. Positive results of experimental studies on prototypes of exhaust gas noise converters-mufflers of original designs for fire trucks with KAMAZ diesel engines are presented.
