Abstract

The unit has a high pressure injection pump with an intake side. Required amount of air added to the fuel is supplied by a calibrated nozzle to the intake side. The air is compressed with the fuel and then pumped and injected as small blisters to the injector nozzle. The expansion of pressure in the combustion chamber provides atomization of the fuel and leads to a homogenous combustion.

Description

Um den Kraftstoff in einem Dieselmotor optimal verbrennen zu können, ist es erforderlich, diesen bei der Einspritzung in den Brennraum so gut, wie möglich, zu zerstäuben.Around to be able to optimally burn the fuel in a diesel engine is it is necessary to do so during injection into the combustion chamber good, as possible, to atomise.

Zu diesem Zweck wird in der hier beschriebenen Erfindung dem Kraftstoff auf der Saugseite der Hochdruckpumpe eine dosierte Menge Luft beigemischt.To For this purpose fuel is used in the invention described herein on the suction side of the high pressure pump admixed a metered amount of air.

Dieses kann durch ein Feindosierventil, eine kalibrierte Düse oder Ähnliches geschehen.This can through a fine metering valve, a calibrated nozzle or similar happen.

Die Luft wird zusammen mit dem Kraftstoff komprimiert und anschließend als kleine Bläschen oder in Lösung mit dem Kraftstoff zu den Einspritzdüsen gepumpt und eingespritzt.The Air is compressed together with the fuel and then as small bubbles or in solution pumped and injected with the fuel to the injectors.

Bei der Expansion auf den Druck im Brennraum unterstützt die Luft die Zerstäubung des Kraftstoffes und führt so zu einer homogeneren Verbrennung.at The expansion on the pressure in the combustion chamber helps the air to atomize Fuel and leads so to a more homogeneous combustion.

Diese reduziert die Neigung zur Rußbildung, so dass der zugehörige Rußfilter kleiner ausgelegt werden kann oder die Regenerierintervalle sowie die Lebensdauer des Filters größer werden.These reduces the tendency to soot, so that the associated one soot filter can be designed smaller or the regeneration intervals as well the life of the filter will be greater.

Die effektivere Verbrennung führt ferner zu einer Absenkung des spezifischen Kraftstoffverbrauches sowie zu einer Leistungssteigerung.The more effective combustion leads also to a reduction of the specific fuel consumption as well as to an increase in performance.
