Abstract

The cold start effect of combustion engines leads to high rate of NOx emissions because the gases temperature of the exhauster is lower than the functioning temperature of selective catalyst reduction systems. This paper aim to present preliminary research, in terms of modelling the thermal field and experimental procedure, for heating the exhaust gases using microwave heating. The experimental procedure was focused on different levels of microwave injected power from 600 W to 3000 W. Two sources of gas were considered in experimental procedure: Corgon with flow rate from 5 l/min to 30 l/min and compressed air at 4 bar pressure. The results of thermal field simulation revealed levels of temperature up to 113 °C. The simulation has been validated by experimental procedure where the levels of temperature were 140 °C for Corgon at 1800 W microwave injected power and 120 °C for compressed air.
