Abstract (en)

[origin: DE19939989C1] The regulation system allows the engine (10) to be operated with a weak fuel mixture or a rich fuel mixture using respective regulation characteristics for each operating mode. The setting and regulation of the engine load is effected by controlling the quantity of fuel injected via the fuel injection device (25) in the weak fuel mixture operating mode and by controlling the quantity of combustion air supplied to the engine in the rich fuel mixture operating mode.

Abstract (de)

Die Erfindung betrifft ein Motorregelsystem für einen Dieselmotor, das einen Mager-Betrieb und einen Fett-Betrieb des Dieselmotors ermöglicht, wobei im Mager-Betrieb eine Lasteinstellung und eine Lastregelung des Dieselmotors durch eine lastbestimmte Einstellung und Veränderung der dem Dieselmotor zur Verbrennung zugeführten Kraftstoffmenge erfolgt. Das Motorregelsystem soll so ausgebildet werden, daß mit dem Dieselmotor auch im Fett-Betrieb instationäre Lastzustände realisiert werden können. Das erfindungsgemäße Motorregelsystem ist zu diesem Zweck so ausgebildet, daß im Fett-Betrieb die Lasteinstellung und die Lastregelung durch eine lastbestimmte Einstellung und Veränderung der dem Dieselmotor zur Verbrennung zugeführten Luftmenge erfolgt. <IMAGE>
