Abstract: PURPOSE: An exhaust gas reduction method for a diesel vehicle is provided to control a smoke limit to generate a thin combustion under a diesel particulate filter (DPF) error, thereby emitting exhaust gas to the air. Visible smoke can be significantly reduced. CONSTITUTION: An exhaust gas reduction method for a diesel vehicle is as follows. Error occurrence of a DPF is determined. If the DPF is determined as an error, a higher value is outputted as a final smoke limit lambda value (&lgr; 3) between a normal lambda value (&lgr; 1) outputted through a normal smoke limit map under a normal DPF and a new lambda value (&lgr; 2) outputted through a new smoke limit map under DPF error. If the DPF is determined as normal, the normal lambda value (&lgr; 1) is outputted as a final smoke limit lambda value (&lgr; 4). [Reference numerals] (AA) DPF error?; (BB) Turn on a warning light; (CC,FF) Number of revolutions of an engine; (DD) Normal smoke limit map and a normal air amount correction map; (EE) New smoke limit map and a new air amount correction factor map; (GG,JJ) Amount of fuel; (HH) Normal lambda value (&lgr; 1) & normal amount of air (A1); (II) Select a bigger one between a normal lambda value (&lgr; 1) and a new lambda value (&lgr; 2) & the normal amount of air (A1) * a correction factor value (X1); (KK) Output a final lambda value (&lgr; 4) & output a final target amount of air (A3) when DPF is normal; (LL) Output a final lambda value (&lgr; 3) & output a final target amount of air (A2) when DPF is normal

Abstract: The present invention discloses an EOBD response method to allow response to reinforced EOBD regulations of EURO-5/6 when a breakdown occurs in related parts affecting an exhaust gas. The present invention comprises; a process to determine a detection status of breakdowns by monitoring EGR-related parts in start ON condition; and a process to shut off EGR by entering into an error mode to turn on a warning light and turning off an EGR valve; and a process to determine a target air volume for inducing lowering of combustion temperatures by application of an error-mode air volume map and to have a target air volume followed through adjustment of a throttle valve.

Abstract: 본 발명은 디젤 차량의 배기가스 저감방법에 관한 것으로, DPF 정상시에는 스모크 리미트를 완화해서 운전성(출력) 향상을 도모할 수 있게 되고, 반대로 DPF 에러시에는 희박한 연소상태가 되도록 스모크 리미트를 제한할 수 있게 됨에 따라 대기중으로 배출되는 가시매연을 크게 줄일 수 있음과 더불어 대기중으로 배출되는 PM의 양을 줄여서 OBD규제를 초과하지 않도록 된 것이다.
