Claims (8)
- 온도 요구에 따라 배기 가스 온도 상승, 배기 가스 온도 제한 또는 배기 가스 온도 강하를 위한 조치들이 실시될 수 있는 내연 기관의 배기 가스 온도 제어 방법에 있어서,상기 온도 요구들은 우선 순위를 갖는데, 부품 보호를 위한 온도 제한이 최고의 우선 순위를 갖고, 최종 온도 요구는 가열 조치 및 냉각 조치가 동시에 적용되지 않도록 가열 조치만 또는 냉각 조치만에 의해 실시되는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항에 있어서, 촉매 변환기의 탈황을 위한 온도 요구는 상기 촉매 변환기의 정상 작동을 위한 온도 요구보다 더 높은 우선 순위를 갖는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항에 있어서, 가열 조치로서 점화의 지연 조절이 이루어지며, 가장 지연된 점화각은 내연 기관의 작동점에 의존해서 제한되는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항에 있어서, 상기 내연 기관의 작동점은 적어도 공기 충전, 회전수 또는 엔진 출력에 대한 값에 의해 규정되는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항에 있어서, 냉각 조치로서, 상기 내연 기관의 배기 가스 시스템 내에서 모델화된 또는 측정된 온도에 의존해서, 공기-연료 혼합물의 농후화가 이루어지는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항에 있어서, 상기 배기 가스 온도 또는 촉매 변환기의 온도가 측정되거나 또는 엔진의 작동값으로부터 모델화되는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
- 제 1 항 내지 제 6 항 중 어느 한 항에 따른 방법을 실시하기 위한 전자 제어 장치.
- 제 1 항에 있어서, 상기 배기 가스 온도 및 촉매 변환기의 온도가 측정되거나 또는 엔진의 작동값으로부터 모델화되는 것을 특징으로 하는 내연 기관의 배기 가스 온도 제어 방법.
