Abstract
A method of purification and utilization of internal combustion engine exhaust gases, due to the ultrasound impact on gases in a special storage tank, has been proposed. Large soot particles of gases due to coagulation are deposited on the bottom of the device and disposed of. The hypothesis of analogy of the gas concentration law and the ratio of soot particles during coagulation has been proven. The soot coagulation coefficient has been determined theoretically and experimentally. An experimental bench has been developed. The technique of assessing coagulation processes by the degree of gas transparency before and after exposure to ultrasound has been developed and used, as well as the technique of calculating equipment and options for designing the devices for ultrasonic purification of exhaust gases.
