<p>PURPOSE: A nitrogen-oxide reducing device of a diesel engine is provided to enhance the quality of an engine by reducing the recirculation of exhaust gas until noise and vibration become optimal according to the inner pressure of a cylinder. CONSTITUTION: A nitrogen-oxide reducing device of a diesel engine comprises a turbo charger(130), a DPF(Diesel Particulate matter Filter), a main muffler(150), a surge tank(170) and an LP-EGR line. The turbo charger is interposed between the exhaust pipe and intake pipe of a diesel engine(100). The DPF is installed on the front end of the turbine of the turbo charger. The main muffler is installed on the back end of the DPF. The surge tank recirculates exhaust gas exhausted through the main muffler, to the turbo charger. The LP-EGR line is connected between the main muffler and the surge tank. The LP-EGR line comprises a blower(160).</p> |
