Abstract
A plasma burner and a diesel particulate filter (DPF) trap that can effectively oxidize and remove a particulate material (PM) within an exhaust gas by preheating fuel and mixing the fuel with the exhaust gas are provided. The DPF includes: a filter that is connected to an exhaust conduit at a side opposite to that of an engine; a plasma burner that is provided within the exhaust conduit between the engine and the filter, and that includes a fuel inlet that supplies fuel and a flame vent that projects a flame by a plasma discharge, and that heats exhaust gas; and a fuel inflow conduit that connects the fuel inlet and a fuel tank.
