The article offers a comparison of the use of ultrasonic and laser exposure in a device for cleaning exhaust gases of internal combustion engines, in order to determine the most effective method to reduce their toxicity and improve the environmental safety of cities. The scheme of an experimental combined ultrasound-laser automobile muffler and the results of the experiment are presented, proving the possibility and effectiveness of using the process of ultrasonic coagulation of solid particles and photo-chemical reaction for cleaning exhaust gases of diesel cars. Dependences confirming the effectiveness of the ultrasound-laser car muffler were obtained. A comparison of methods for cleaning car exhaust gas by ultrasound, laser radiation and the combined effects of both methods is presented.
