Abstract

Ein Verfahren zur Unterdrückung des beim Übergang von Zug- auf Schubbetrieb auftretenden Ruckelns einer zum Antrieb eines Kraftfahrzeuges dienenden Brennkraftmaschine, bei welchem zur Dämpfung des Drehmomentabbaues zumindest ein Zylinder früher als die anderen Zylinder abgeschaltet wird, ist dadurch verbessert, daß gleichzeitig mit dem Abschalten des ersten Zylinders das Gemisch der anderen Zylinder um einen Wert angefettet wird, der in der Summe zusammen mit dem abdampfenden Kraftstoff-Wandfilm und der vom abgeschalteten Zylinder gepumpten Luft wieder ein stöchiometrisches oder leicht mageres Gemisch ergibt. Dadurch kann die Emission von HC und CO reduziert werden.

Figure 00000001
A method for suppressing the jerking occurring during the transition from pulling to pushing operation of an internal combustion engine used to drive a motor vehicle, in which at least one cylinder is switched off earlier than the other cylinders to dampen the torque reduction, is improved in that at the same time as the first is switched off Cylinder, the mixture of the other cylinders is enriched by a value which, together with the evaporating fuel wall film and the air pumped by the deactivated cylinder, again results in a stoichiometric or slightly lean mixture. This can reduce the emission of HC and CO.
