Description
自動車に配置された内燃機関の許容可能な有害物質排出に関する法規は厳しくなる一方なので、内燃機関の作動中の有害物質排出をできるだけ僅かに抑え続けることが必要である。このことは、空気/燃料混合気の燃焼プロセス中に内燃機関の各シリンダに発生する有害物質を低減することで行うことができる。その一方で内燃機関では排ガス後処理システムも使用されており、このシステムは空気/燃料混合気の燃焼プロセス中に各シリンダに発生する有害物質を無害物質に変換している。
本発明の有利な構成は従属請求項に記載されている。
図面
図1は内燃機関を示しており、
図2は、内燃機関を制御するためのプログラムのフローチャートを示している。なおこれらの図面中において同じ機能又は同じ構造の部材にはすべて同一の符号が付されている。
内燃機関(図1)は吸気系1、エンジンブロック2、シリンダヘッド2および排気系4を有する。吸気系1は有利にはスロットルバルブ5と、集合管6および吸気管7を有し、この吸気管7はシリンダZ1の吸気ダクトを介してエンジンブロック2へ導かれている。エンジンブロック2はさらにクランクシャフト8を含み、このクランクシャフト8はコネクティングロッド10を介してシリンダZ1のピストン11と連結されている。
制御装置25のプログラムメモリ内にはプログラムが記憶されており、このプログラムは内燃機関の作動中に処理され得る。
