Abstract
【解決手段】ピストンが上死点と下死点との間を往復運動している、部分負荷の下で動作する、直噴で過給式の多気筒内燃エンジン、特にディーゼル形式のエンジンの残留燃焼ガスを掃気する方法であって、燃焼ガス掃気段階を、エンジンの排気行程Eの間に少なくとも1つの排気弁18の開閉シーケンスと、排気弁18の当該開閉シーケンス中に少なくとも1つの吸気弁28の少なくとも1つの開閉シーケンスと、によって実施する方法に関する。本発明によれば、当該方法は、吸気圧力Paと排気圧力Peとの圧力差であって、吸気圧力に好適な圧力差を得るために、掃気段階中、吸気弁28の閉止時間を制御して排気圧力Peを減少させることを特徴とする。
