Modeling of Purification Process of Vehicle Exhaust Gases under the Influence of Ultrasound
Annotatsiya
Research is related to ultrasonic purification of exhaust gases of internal combustion engines of vehicles. The hypothesis of using ultrasonic radiation for purification of exhaust gases from harmful impurities and solid particles is proposed. The scheme of the ultrasonic muffler developed by the authors is presented. A mathematical model of the coagulation of exhaust gas particles in an ultrasonic muffler has been developed. Theoretical dependencies of coagulation coefficient are obtained. An experimental stand has been developed that models an ultrasonic muffler. The results of experimental studies proving possibility and efficiency of using the process of ultrasonic purification from harmful impurities and solid particles are presented. The dependencies of the content of harmful impurities in the exhaust gases were obtained, without exposure and under the influence of ultrasound at different engine revolutions. Experimental relationships of changes in toxic impurities and solid particles (exhaust carbon) are used in the calculation and design method when creating the design of an ultrasonic muffler
