die an der Abgasrückführung beteiligten
Zylinder
Beispielsweise können die als Geberzylinder im Abgasrückführsystem fungierenden Zylinder im so genannten Miller-Atkinson-Verfahren betrieben werden, während die übrigen Zylinder konventionell betrieben werden. Der Vorteil gegenüber einem Betrieb mit reinem Miller-Atkinson-Verfahren liegt darin, dass bei gleichem Hubraum höhere Drehmomente möglich sind, da das Verfahren einen deutlichen Füllungsverlust bedeutet oder als Ausgleich wesentlich höhere Aufladegrade bedingt.For example can as the master cylinder in the exhaust gas recirculation system operating cylinder operated in the so-called Miller-Atkinson process be while the remaining Cylinders are operated conventionally. The advantage over one Operation with pure Miller-Atkinson method is that at same displacement higher Torques possible are because the process means a significant loss of fill or as compensation significantly higher Charging levels conditionally.
Eine weitere Variante besteht in einer Mischung aus Zylindern, die mit einer HCCI (Homogeneous Charge Compression Ignition) – Verbrennung betrieben werden, und Zylindern, die mit konventioneller Verbrennung betrieben werden. Die konventionellen Zylinder dienen dabei als Geberzylinder für die HCCI-Zylinder, deren temperaturabhängige Selbstzündung durch die Abgasrückführung gesteuert werden kann.A Another variant consists of a mixture of cylinders with a HCCI (Homogeneous Charge Compression Ignition) - combustion operated and cylinders operated with conventional combustion become. The conventional cylinders serve as master cylinder for the HCCI cylinders, their temperature-dependent self-ignition controlled by the exhaust gas recirculation can be.
