Through establishing a test system of coaxial dielectric barrier discharge type non-thermal plasma reactor, using Q-V Lissajous figure method to measure its electrical parameters, optical emission spectrum of NO/N2 mixed gas system was analyzed, and the effects of the applied voltage peak-peak value(VP-P) on the optical emission spectrum intensity of NO, N2 excited state species were studied when...
Hybrid electric vehicle (HEV) traction is one of the most promising technologies, which has significant improvements in vehicle performance, energy utilization efficiency, and polluting emissions as well. What type of hybrid system be might suitable for conventional driveline system, hybrid driveline and pure electrical driveline? Is there a hybrid system which is not only suitable for all of these...
The design method of hydraulic system of power split full hybrid transmission is studied. Oil volume flow and pressure requirement is confirmed according to the vehicle control strategy. Mechanical gear pump and electric pump are used to supply oil flow for all driving modes. Self-adapted pressure regulation circuit is designed to supply high pressure oil for brake engagement. Dynamic model of hydraulic...
Based upon the principle of dielectric barrier discharge theory, a non-thermal plasma (NTP) reactor was designed, and the bench test system of the NTP assisted catalyst (NPAC) technology was established with the La0.8K0.2Co0.5Mn0.5O3 catalyst system. The experiment was carried out, and the discharge parameters of the NTP reactor were investigated, which had remarkable effect on the removal of soot...
A new non-thermal plasma reactor was designed and the measurement of the reactor's discharge power was introduced. Then the experiment was carried out to research the effect on the removal of NOx in diesel engine exhaust with non-thermal plasma assisted catalyst technology. The results showed that NO was oxidized to NO2 with the increase of discharge power, and the total amount of NOx was not reduced...

In order to study the NOx plasma chemistry reaction mechanisms in NO/N2/C3H6 and NO/N2/O2/C3H6 mixture gases, a coaxial tubular plasma reactor based on dielectric barrier discharge was designed, the effects of the C3H6 initial concentration on NO oxidation and reduction reactions were observed. The results showed that NO reduction reaction was very low and energy consumption was very high in NO/N2...
Non-thermal plasma (NTP) technology is considered to be one of the most promising technologies in diesel exhaust after-treatment, which has the advantages of simple operation, high conversion efficiency and no secondary pollution. In this paper, a NTP reactor was designed based upon the dielectric barrier discharge theory. The bench test was carried out and the reduction of carbon particles from diesel...
