    • PURPOSE: A selective catalytic reduction system, capable of improving the efficiency of a turbo charger in an exhaust gas treating process, is provided to convert the urea aqueous solution, emitted to exhaust gas, into ammonia and to convert the converted ammonia into nitrogen molecule and water. CONSTITUTION: A selective catalytic reduction system comprises a SCR(Selective Catalytic Reduction) reactor(132) and a urea aqueous solution emitting part(134). The SCR reactor is installed in the downstream passing through the turbocharger(120) from the engine(110) of the exhaust gas discharge line. The exhaust gas mixed with the urea aqueous solution sprayed from the urea aqueous solution emitting part flows in the SCR reactor. The urea aqueous solution emitting part comprises an engine. The urea aqueous solution emitting part is installed in an exhaust gas receiving part(112) located on the upper stream of an exhaust gas discharge line(140). The urea aqueous solution receiving part emits the urea aqueous solution to at least one part of the exhaust gas flowing in the turbocharger.

    • An apparatus and a method for automatically combusting particulate materials collected in a diesel particulate filter are provided to prevent a great amount of particulate materials from being collected in a diesel particulate filter by combusting particulate materials through compressed air or exhaust gas supplied to the diesel particulate filter. An apparatus for automatically combusting particulate materials collected in a diesel particulate filter comprises an engine(10), an electronic control unit(20) and a diesel particulate filter(30). The diesel particulate filter collects particulate materials contained in exhaust gas discharged from the engine. A pipe line(60) supplies compressed air of 8-9bar or exhaust gas of 2-2.5bar to the diesel particulate filter. A solenoid valve opens and closes the pipe line according to a control signal of the electronic control unit.

    • PURPOSE: An exhaust gas purification apparatus is provided to prevent the backflow of exhaust gas flowing into an intake pipe from an exhaust gas recirculation pipe. CONSTITUTION: An exhaust gas purification apparatus(100) comprises an exhaust pipe(108), a first purifying unit(112), and an exhaust gas recirculation pipe(114). The exhaust pipe discharges exhaust gas. The first purifying unit is placed in the exhaust pipe between the end of a combustion unit(102) and the front part of a turbine of a turbocharger(106). The first purifying unit purifies the exhaust gas discharged from the combustion unit. The exhaust gas recirculation pipe is installed between the end of the first purifying unit and the front part of the turbine. The exhaust gas recirculation pipe delivers some of firstly purified gas to an intake pipe.
