Studying the Process of the Internal Combustion Engine Exhaust Gas Purification by an Electric Pulse

Abstract

The article deals with method of purifying the exhaust gases in an automobile muffler or other transport equipment using electrical pulses. Electrical pulses are formed between the two ring electrodes (anode and cathode) installed in series along the gas flow. The physical picture of the process is described. A mathematical model has been developed and studied. A deterministic relationship has been established between the engine volume, the number of the crankshaft revolutions, the electric field strength and the charge strength and dynamic viscosity of the gas. Experimental studies have been carried out. The goal of the experiment was to confirm the hypothesis of impact ionization of exhaust gases. The effectiveness of electrical pulse purification has been proven.

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

“…The authors conducted an experiment that proved the effectiveness of the design with electrodes built into the muffler [9]. Figure 1 shows the experimental stand of an electric pulse muffler.…”

Establishing the parameters of the operation mode of the electric pulse automobile muffler

“…Corona discharge compared to spark discharge is more resistant to voltage spikes, since part of the energy generated in the ionization process is smoothly dissipated during the movement of electrons from the cathode, therefore, the voltage values do not drop dramatically. Moreover, due to the effect of the corona discharge, the surrounding gas becomes more conductive, which leads to an increase in the virtual diameter of the electrode and increases the efficiency of the ionization process [13]. In addition, the spark discharge can cause destruction of the anode under certain conditions, namely when the length of the discharge gap is small, there is a specific destruction of the anode metal, which is called erosion [14].…”
