The article considers the urgent issue of reducing the toxicity of harmful components of car exhaust gases. In order to solve this problem, a direction was proposed to improve the system for cleaning exhaust gases of internal combustion engines by introducing an ultrasonic emitter into the muffler device. An experimental installation of a muffler with an ultrasonic emitter was made The experimental plan for determining the effectiveness of the ultrasonic muffler based on the method of similarity theory and dimensional analysis was made. Dimensionless criteria have been obtained that make it possible to determine the optimal operating modes of the ultrasonic muffler.
