APPARATUS FOR DECREASING EXHAUST GAS AND METHOD FOR DECREASING EXHAUST GAS

摘要

PURPOSE: An apparatus and a method for decreasing exhaust gas are provided to noticeably reduce the PM combustion temperature of exhaust gas and to remarkably save the energy, which is consumed to drive a temperature control unit. CONSTITUTION: An apparatus for decreasing exhaust gas comprises a FBC(Fuel Borne Catalyst) supply unit(100), a temperature control unit(200) and an exhaust gas reducing unit(300). The FBC supply unit supplies FBC to fuel, which is supplied to a diesel engine(400). The temperature control unit is formed on a discharge pipe(500) and raises the temperature of the exhaust gas. The exhaust gas reducing unit comprises Perovskite catalyst coating DPF(310), which is mounted on the rear end of the temperature control unit. The Pervoskite catalyst coating DPF burns the PM(Particulate Matters) in the exhaust gas.
