Abstract

디이젤 엔진의 디이젤 매연필터의 제어된 재생의 방법에 있어서, 디이젤 매연필터는 배기가스관에 평행하게 연결된 복수의 부위로 나누어지고 이 복수의 부위중의 적어도 하나는 배기가스의 유입이 디이젤 매연필터의 하류에서 측정된 배기가스의 온도에 반응하여 차단된다.In a method of controlled regeneration of a diesel particulate filter of a diesel engine, the diesel particulate filter is divided into a plurality of portions connected in parallel to an exhaust gas pipe, and at least one of the plurality of portions is configured such that the inflow of exhaust gas is downstream of the diesel particulate filter. It is blocked in response to the temperature of the exhaust gases measured at.

디이젤 매연필터의 하류의 배기가스온도가 초과하면 이 부위는 대응필터부위가 감소 또는 차단되도록 배기가 스 스트림으로 부터 부분 또는 완전하게 차단되는 한편 나머지 부위를 통해 매스 유동량은 제생을 다시 제어하거나 또는 그것을 불연속시키는 방식으로 증가된다.If the exhaust gas temperature downstream of the diesel particulate filter is exceeded, this area is partly or completely blocked from the gas stream so that the corresponding filter part is reduced or shut off, while the mass flow through the remaining part re-controls the control or Increased in a discontinuous manner.
