| Abstract: | A wire-to-cylinder reactor with HV pulse generator has been developed for the removal of particulates in diesel engines. This paper discusses the removal efficiency of the instrument under the different voltage levels and frequencise of the pules. And the experimental investigation has been carried out under a range of loads and speeds. The experimental results show that the voltage level and frequency of the pulse are main factors which influence the removal efficiency and among them voltage level is the most important factor. Effects of the pulse corona technology used to remove the particulates of diesel engines are clear. It confirms that this technology is a predominant means to reduce the particulates in diesel engines. |
