Development of Calculation Methodology for Optimizing the Operating Mode of an Electric Pulse Unit for Cleaning Exhaust Gases

Abstract

The results of research, devoted to operation of an electric pulse muffler designed for cleaning exhaust gases of an internal combustion engine, are presented in this article. The problem considered in this research is establishing the optimal operating mode of the electric pulse muffler by changing the parameters of the distance between the electrodes and the frequency of the electric pulse. To solve this problem, experimental research on laboratory and experimental stands was carried out, which confirmed effective reduction of the gas smoke indices at adjustment of the specified parameters. As a result, a methodology was developed to calculate the optimal values of the distance and frequency parameters, at which the operation of the electric pulse muffler will be considered productive and the degree of gas purification will be effective. The optimum value of the distance between electrodes is 0.78-6 ∙10-3 m with an electric pulse frequency in the range of 127-128∙103Hz.
