Abstract

Ein Verfahren zur Regelung der Vollasteinspritzmenge einer Dieselbrennkraftmaschine mit einer festgelegten Vollasteinspritzmenge im stationären Zustand weist folgende Phasen auf:A method for controlling the full-load injection quantity a diesel engine with a fixed Full load injection quantity in the steady state shows following phases:

Eine erste, instationäre Phase, in der die Vollasteinspritzmenge über die Vollasteinspritzmenge im stationären Zustand auf eine Übermenge erhöht wird.A first, unsteady phase in which the full-load injection quantity about the full load injection quantity in the stationary Condition is increased to an excess.

Eine zweite, zeitlich begrenzte Phase, in weicher die Vollasteinspritzmenge auf dem Niveau der Übermenge gehalten und am Ende dieser Phase auf die Vollasteinspritzmenge im stationären Zustand reduziert wird.A second, time-limited phase, in which the Full load injection quantity at the level of the excess quantity held and at the end of this phase on the full load injection quantity is reduced in the steady state.

Eine dritte Phase, in der in bekannter Weise der Dieselbrennkraftmaschine die Vollasteinspritzmenge im stationären Zustand zugeführt wird.
