Abstract: PURPOSE: An integrated type catalyst purifying apparatus is provided to simultaneously reduce particulate materials and nitrogen oxide materials from the exhaust gas of diesel engines and to minimize the volume of a catalytic apparatus. CONSTITUTION: Exhaust gas is introduced through an introducing pipe(110). A filter(101) for eliminating particulate materials eliminates particulate materials from the exhaust gas. An exhausting pipe(150) discharges the purified exhaust gas through the filter to outside. A lean NOx catalyst(LNT) coating part oxidizes hydrogen carbide, carbon monoxide, volatile materials, and nitrogen monoxide. During the oxidization, the hydrogen carbide and nitrogen oxides are reacted to generate ammonia as an intermediate product. A selective catalytic reduction catalyst coating part uses the ammonia from the LNT coating part to eliminate non-purified nitrogen oxide materials.
