摘要： A plasma system is provided for removing soot and nitrogen oxide (NOx) in the exhaust gas of diesel engines. The system is comprised of a diesel particulate filter for adopting a honeycomb type porous element and at least one pair of electrodes; a plasma reactor for generating a predetermined amount of plasma, mounted downward or upward the diesel particulate filter; a catalytic reactor filled with a catalyst selected from 1B metal group, mounted downward the plasma reactor or the diesel particulate filter; and a means for supplying hydrocarbon to the exhaust gas, connected to a proper position upward the plasma reactor. Therefore, the soot and NOx in the exhaust gas, which are not only harmful to humans, but also which pollute the environment could be effectively removed under a normal pressure.
