Claims (6)
- 燃焼気体の掃気段階が、エンジンの排気行程(E)中に少なくとも1つの排気弁(18)を開閉するシーケンスと、前記排気弁の開閉シーケンス中に少なくとも1つの吸気弁(28)を開閉する少なくとも1回の開閉シーケンスと、によって実施される、上死点(PMH)と下死点(PMB)との間を往復運動するピストンを有する直噴過給式の多シリンダ内燃エンジン(10)の残留燃焼気体を掃気する方法において、
シリンダの前記排気行程の期間中において、掃気段階の終了時のシリンダの吸気圧力(Pa)がシリンダの吸気上死点(PMHa)の後における掃気段階の終了時のシリンダの排気圧力(Pe)を上回る場合、前記排気行程の下死点(PMBe)後に前記シリンダの排気弁(18)を開閉するシーケンスを開始することと、前記排気行程における前記シリンダの前記排気弁の開閉シーケンスを遅くとも次の上死点(PMHa)で終了することと、を含むことを特徴とする、エンジンの残留燃焼気体を掃気する方法。 - 前記排気弁(18)の開閉シーケンスを開始する前記クランク角度(e1)で、前記吸気弁(28)の開閉のシーケンスを開始することを特徴とする、請求項1に記載のエンジンの残留燃焼気体を掃気する方法。
- 前記排気弁(18)の開閉シーケンスを開始する前記クランク角度(e1)後のあるクランク角度(a1)で、前記吸気弁(281)の開閉シーケンスを開始することを特徴とする、請求項1に記載のエンジンの残留燃焼気体を掃気する方法。
- 遅くとも前記排気行程(E)の終了時に前記吸気弁(28)を閉じることを特徴とする、請求項1から3のいずれか1項に記載のエンジンの残留燃焼気体を掃気する方法。
- 前記排気弁が開く角度(e1)か該角度後のある角度(a1)から前記吸気上死点(PMHa)までの前記排気行程の領域(a1−PMHa)で、前記吸気弁(28)の開閉シーケンスを実施することを特徴とする、請求項1から4のいずれか1項に記載のエンジンの残留燃焼気体を掃気する方法。
- 前記排気弁のリフトの高さよりも低くなるように前記排気行程中に前記吸気弁(281)のリフトの高さを減少させることを特徴とする、請求項1から5のいずれか1項に記載のエンジンの残留燃焼気体を掃気する方法。
