EXHAUST GAS POST-TREATMENT APPARATUS OF A DIESEL ENGINE, CAPABLE OF SUCKING EXHAUST GAS AT AN EQUAL FLOW UNIFORMITY

摘要

PURPOSE: An exhaust gas post-treatment apparatus of a diesel engine is provided to improve the catalytic reaction efficiency of a DOC(Diesel Oxidation Catalyst) when treating exhaust gas.;CONSTITUTION: An exhaust gas post-treatment apparatus of a diesel engine comprises an oxidation unit(1), an adsorption unit(2), a discharge unit(3), and a baffle. The oxidation unit comprises a DOC(Diesel Oxidation Catalyst) and a hollow DOC cover(10). The DOC is inserted into the DOC cover. The adsorption unit is placed in a rear part of the oxidation unit. The adsorption unit comprises a DPF(Diesel Particulate Filter) and a hollow DPF cover(20). The DPF is inserted into the DPF cover. The discharge unit comprises a hollow outlet cover(30) and an end plate(32). Purified exhaust gas is discharged through the outlet cover. The end plate covers the outlet cover. The baffle installed in front of the DOC and equally diffuses the exhaust gas.;COPYRIGHT KIPO 2012
