Besonderheiten der thermodynamischen Analyse von DE-Ottomotoren

Michael Bargende; Christine Burkhardt; Alfred Dipl.-Ing. Frommelt

In diesem Beitrag, der in Zusammenarbeit der Universitat Stuttgart und DaimlerChrysler entstanden ist, werden Modellansatze zur Brennverlauf- und Arbeitsprozessrechnung bei DE-Ottomotoren im Schichtladebetrieb formuliert und diskutiert. Durch die Kraftstoffeinspritzung wahrend des Kompressionshubes andert sich die im Zylinder befindliche Ladungsmasse in Abhangigkeit des Verdampfungsverlaufes des Kraftstoffs. Dadurch wird die Energiebilanz (innere Energie, Enthalpiestrom des verdampfenden Kraftstoffes und Verdampfungswarme) verandert. All dies beeinflusst die wahrend der Kompression durchzufuhrende Nulllinienbestimmung des gemessenen Druckverlaufs. HC- und CO-Emissionen mussen im Rahmen eines Energiebilanzvergleiches unbedingt berucksichtigt werden. Motorisch gesehen wird deutlich, dass hier noch ein betrachtliches Wirkungsgradoptimierungspotenzial vorhanden ist.
