DETERMINING THE EFFICIENCY OF CLEANING VEHICLE EXHAUST GASES WITH AN ULTRASONIC MUFFLER DEPENDING ON THE ENGINE OPERATING MODE AND ULTRASOUND POWER

The dependence has been obtained that links the degree of coagulation of soot particles, the parameters of the ultrasonic equipment, the geometric dimensions of the ultrasonic muffler, the frequency characteristics of ultrasound, and the parameters of the engine operating mode. In the paper is presented solving of a problem of determining the number of particles in 1 cm³ of exhaust gas depending on the smoke index. An example of calculating the required ultrasound power for a full-size ultrasonic vehicle muffler bench has been given.
