Abstract

Brennkraftmaschine mit innerer Verbrennung mit direkter Einspritzung von Kraftstoff in den Zylinder, bei der ein Einlaßsystem und ein Brennraum zur Erzeugung einer Ladungsschichtung im Zylinder ausgebildet sind. Eine extreme Verringerung der Emissionen kann dadurch erreicht werden, daß eine Einrichtung zur Umschaltung zwischen geschichtet magerem Betrieb und geschichtet stöchiometrischen Betrieb vorgesehen ist, die im wesentlichen in Abhängigkeit von der jeweils erforderlichen Abgasqualität schaltet.Internal combustion engine with direct injection of fuel into the cylinder, in which an intake system and a combustion chamber for generating a charge stratification are formed in the cylinder. An extreme reduction in emissions can be achieved by providing a device for switching between stratified lean operation and stratified stoichiometric operation, which switches essentially depending on the exhaust gas quality required in each case.
