Experimental determination on cleaning the exhaust gas of an automobile muffler by an electric pulse

Abstract

Nowadays, creating an environmentally reliable car by reducing the volume of harmful gases in it is a global problem of mankind. For this reason, one of the main areas of research is to improve the exhaust gas cleaning system of internal combustion engines. However, to date, there are no universal designs that would improve the performance of the purification system. In this regard, the development of new vehicle exhaust system designs based on an effective cleaning method is an urgent task. The article highlights the results of scientific and experimental research of the authors on the development of new designs of automobile exhaust muffler working on the basis of the method of electro-pulsed cleaning, designed to reduce the concentration of harmful exhaust gases. The developed experimental installation of the electric-pulse muffler performs gas purification by feeding an electric shock discharge to the electrodes installed in the muffler. The experimental data obtained show changes in the gas transparency depending on changes in the distance between the electrodes. Regression-correlation analysis established empirical dependences of gas transparency values on changes in the distance between the electrodes.
