Abstract

Regeneration of diesel particulate filter(DPF)is experimentally investigated by a self-designed non-thermal plasma(NTP)injection system with oxygen as the gas source. Three control schemes of oxygen flow are proposed - the oxygen flow for scheme 1 remains constant at 5 L/min; increases from 3 L/min to 7 L/min for scheme 2; and decreases from 7 L/min to 3 L/min for scheme 3. The total oxygen amount for three schemes keeps equal. The effects of the oxi

dation of PM and DPF regeneration are discussed by measuring the volume fractions of CO and CO

during the regeneration process. The results reveal that the mass flow rate of O

increases remarkably with the increasing oxygen flow to promote the oxidation of PM. The volume fractions of CO and CO

for scheme 1 rise sharply and then remain stable; the volume fractions of CO and CO

for scheme 2 tend upward by three steps; the volume fractions of CO and CO

for scheme 3 tend downward by three steps. The mass of carbon in CO

and CO+CO

has same varying trend

and the total carbon is in descending order of scheme 3

scheme 2 and scheme 1. The variable flow control has better regeneration effect of DPF than the constant flow control. The remarkable effect of DPF regeneration can be reached by gradually making oxygen flow decrease during the experimental period.
