Abstract: The purpose of the article is to compare the efficiency of using electro-pulse and ultrasonic mufflers for cleaning exhaust gases from internal combustion engines of automobiles. The authors have developed full-size stands for conducting experiments with both types of mufflers on gasoline and diesel engines. Experimental studies have shown that electro-pulse mufflers are more effective in reducing the smoke of diesel engine exhausts, while ultrasonic mufflers are promising for cleaning exhaust gases from solid particles of gasoline engines. In the electro-pulse muffler, at the considered values of the angular velocity of the engine, the smoke indicators of the gas decreased to approximately 30%, while in the ultrasonic one, to 15%. The changes in the mass of the sold particles in the ultrasonic muffler of a diesel engine and a comparison with a gasoline engine show that ultrasonic mufflers have a lot of potential to stop solid particles from forming in the gas flow. In particular, the mass of the precipitated particles in a gasoline engine is 3 times greater than in a diesel engine. The alternative mufflers studied in the article allow for the purification of exhaust gases from solid particles, reducing their negative impact on the environment and giving impetus to the development of environmentally friendly motor transport.
