In order to achieve simultaneous removal of particulate matters (PM) and NOX in diesel exhaust, a new kind of aftertreatment prototype has been developed. The prototype combined effects of static, cyclone, non-thermal plasma and hydrocarbon selective catalytic reduction. Experiments have been carried out with standard gases simulating diesel exhaust. Physical and chemical effects that took place in the prototype are as follows: the collection of PM by electrostatic-cyclone system, the oxidative combustion of PM, the selective catalytic reduction of NOX, and the reaction between PM and NOX. The effect of non-thermal plasma makes the density of NO decrease and that of NO2 increase, whereas, the amount of NOX remains the same. Employing catalyst coupled with non-thermal plasma debase the temperature by about 50◻, there the peak value of transform rate appears. All of catalyst, non-thermal plasma, and deoxidizing HC are active to decrease combustion temperature of PM, moreover, the effect of all of them together decrease the temperature to about 280◻, which is informing. It is realized that PM and NOX were removed by Physics and chemical effects mentioned above.
