Title (DE) KRAFTSTOFFVERSORGUNGSSYSTEM FÜR EINE BRENNKRAFTMASCHINE
(EN) FUEL-SUPPLY SYSTEM FOR INTERNAL-COMBUSTION ENGINES
(FR) SYSTEME D'ALIMENTATION EN CARBURANT POUR UN MOTEUR A COMBUSTION INTERNE
Abstract:
(DE) Es wird ein Kraftstoffversorgungssystem für eine Brennkraftmaschine vorgeschlagen, die eine elektrische Kraftstoffpumpe, einen Kraftstoffdruckregler sowie ein Kraftstoffzumeßsystem umfaßt, wobei die Förderleistung der Kraftstoffpumpe abhängig von Betriebskenngrößen steuerbar ist und der Kraftstoffdruck mittels eine entsprechenden Druckreglerkennlinie durch Variation der Förderleistung beeinflußt werden kann.
(EN) Proposed is a fuel-supply system for internal-combustion engines, the system having an electric fuel pump, a fuel-pressure regulator and a fuel-metering unit. The delivery capacity of the pump can be controlled as a function of the operating parameters, and the fuel pressure can be controlled, using a suitable pressure-control characteristic, by varying the delivery capacity.
(FR) On propose un système d'alimentation en carburant pour un moteur à combustion interne, comportant une pompe de carburant électrique, un régulateur de pression de carburant ainsi qu'un système de dosage de carburant, le débit de la pompe de carburant pouvant être commandé en fonction des paramètres de fonctionnement et la pression de carburant pouvant être régulée en utilisant une caractéristique du régulateur de pression, par variation du débit.
