Abstract

The implementation of a plasma-catalytic reactor for effective remediation of diesel exhaust requires an overall power consumption <5% of the total engine power. The efficiency of NO_x reduction is a complex function of many parameters, such as pulse characteristics, the features of energy deposition in a plasma, the reactor design, and energy transfer from pulser to reactor. The nanosecond time frame pulse modulator for creation of nonthermal plasma is also a complex engineering problem. Here the reliability, price and high efficiency are the issues to meet total low energy consumption. This paper discuses all these items.
