In this article is presented a new method of ultrasonic cleaning of exhaust gases of diesel engines by coagulation of soot particles and their subsequent sedimentation. The analytical modelling of the particle motion in a vertical muffler stand was carried out, taking into account the ultrasonic effect and gravitational forces. Experimental studies of the developed stand confirmed that ultrasound promotes agglomeration and sedimentation of soot, reduces the CO₂ content and increases the O₂ concentration in the exhaust gases. The maximum cleaning efficiency is achieved with the simultaneous use of all the ultrasonic emitters. The results of the work can be used in designing modern exhaust gas cleaning systems.
