Abstract

Die Erfindung bezieht sich auf ein Förderaggregat zur Förderung und Dosierung alternativer Kraftstoffe wie zum Beispiel Methanol, Ethanol, welches in Ein- oder Mehrzylinderbauweise (14) ausgeführt ist und alternativen Kraftstoff über ein Vorförderaggregat (52) aus einem Kraftstoffreservoir (50) fördert und einem Teil (57) eines Reformierungssystemes (57) auf erhöhtem Druckniveau zuführt. Das Förderaggregat (1) ist mittels eines regelbaren Fremdantriebes (53) angetrieben und umfaßt Dichtelemente (11, 18, 20) aus beständigem Material. Die mit dem alternativen Kraftstoff in Kontakt tretenden Flächen (28, 29, 34, 35, 36, 37 und 38) sowie Anbauteile (3, 15) sind mit einer Beschichtung versehen oder aus einem korrosionsbeständigen Material gefertigt.

The invention relates to a delivery unit for delivering and metering alternative fuels such as methanol, ethanol, which is designed in a single or multi-cylinder construction (14) and delivers alternative fuel via a pre-delivery unit (52) from a fuel reservoir (50) and in part (57) of a reforming system (57) at an increased pressure level. The conveying unit (1) is driven by a controllable external drive (53) and comprises sealing elements (11, 18, 20) made of resistant material. The surfaces (28, 29, 34, 35, 36, 37 and 38) that come into contact with the alternative fuel as well as add-on parts (3, 15) are provided with a coating or made of a corrosion-resistant material.
