The authors have developed and investigated a mathematical model of the operation of an ultrasonic automobile muffler, which allows calculating the necessary parameters for effective work on cleaning the exhaust gas of motor transport. An experiment has been conducted to prove the effectiveness of ultrasonic exposure for cleaning the exhaust gas of motor vehicles. There are considered forces acting on a gas particle moving in an ultrasonic automobile muffler, the values of the velocities of motion of coagulated particles horizontally and vertically. There are determined the coagulation coefficient in an ultrasonic muffler. The effectiveness of ultrasonic exposure to the exhaust gas of motor transport has been proven during the experiment and has a promising development of this direction of cleaning aerosols from harmful impurities by the proposed method. According to the results of the experiment, the concentration of hydrocarbon CH decreased by more than 2 times, at 1000 rpm from 50 ppm/min to 27 ppm/min.
