Description
Technisches GebietTechnical area
Die Erfindung betrifft allgemein Kraftstofffilter. Insbesondere betrifft die Erfindung antioxidierende Kraftstofffilter. Ganz speziell betrifft die Erfindung Kraftstofffilter zur Verwendung in Verbrennungsmotoren, die mit Biokraftstoffen, insbesondere mit Biodiesel, betrieben werden. Stand der TechnikThe The invention relates generally to fuel filters. In particular, it concerns the invention antioxidant fuel filter. Especially concerned the invention fuel filter for use in internal combustion engines, which are fueled by biofuels, in particular biodiesel. State of the art
In der Vergangenheit stand das Thema der Oxidationsstabilität von herkömmlichen Kraftstoffen nicht unbedingt im Fokus, da der in diesen mineralischen Kraftstoffen enthaltene Schwefel als internes Antioxidanz wirkte. Durch die zunehmende Entschwefelung und die immer stärkere Zunahme an Kraftstoffkomponenten mit deutlich geringerer Oxidationsstabilität, insbesondere Biodiesel, müssen den Kraftstoffen nunmehr Additive zugegeben werden, die die Oxidationsstabilität verbessern.In the past was the topic of oxidation stability not necessarily in focus on conventional fuels, since the sulfur contained in these mineral fuels as an internal antioxidant acted. Due to the increasing desulfurization and the ever increasing increase in fuel components with significantly lower oxidation stability, in particular Biodiesel, additives must now be added to the fuels which improve the oxidation stability.
Als Biokraftstoffe werden Kraftstoffe für Verbrennungsmotoren bezeichnet, die aus Biomasse hergestellt werden. Biokraftstoffe verfügen über eine bessere CO2-Bilanz als fossile Diesel- oder Ottokraftstoffe. Zu den bekanntesten Biokraftstoffen zählt der Biodiesel, ein Fettsäuremethylester (FSME, englisch FAME), der vor allem aus Raps oder Soja hergestellt werden kann. Die heutigen Dieselmotoren vertragen reines Pflanzenöl nicht ohne weiteres. Wegen der hohen Zähigkeit von Pflanzenöl müssen die Fahrzeuge, z. B. mit Heizsystemen, umgerüstet werden. Zur Herstellung von Biodiesel wird das Pflanzenöl mit Methanol und verschiedenen Reagenzien (vor allem Kalium- oder Natriumhydroxid) versetzt. Bei Normaldruck und Temperaturen von ca. 60°C werden die Esterbindungen der Triglyzeride des Pflanzenöls getrennt und die entstehenden Fettsäuren mit dem Methanol verestert (Umesterung). Durch die Umesterung hat das Endprodukt eine deutlich geringere Viskosität als das unbehandelte Pflanzenöl und kann aufgrund seiner physikalischen Eigenschaften als Ersatz für Dieselkraftstoff verwendet werden. Abhängig von der verwendeten Pflanzensorte sind die gebildeten Ester teilweise ein- bis mehrfach ungesättigt, was zu einer verringerten Oxidationsstabilität führt.Biofuels are fuels for internal combustion engines, which are produced from biomass. Biofuels have a better CO2 balance than fossil diesel or petrol. One of the best-known biofuels is biodiesel, a fatty acid methyl ester (FSME, English FAME), which can be produced mainly from oilseed rape or soybeans. Today's diesel engines do not tolerate pure vegetable oil readily. Because of the high toughness of vegetable oil, the vehicles, z. B. with heating systems to be converted. For the production of biodiesel, the vegetable oil is mixed with methanol and various reagents (especially potassium or sodium hydroxide). At normal pressure and temperatures of about 60 ° C, the ester bonds of the triglycerides of the vegetable oil are separated and the resulting fatty acids esterified with the methanol (transesterification). By transesterification, the end product has a significantly lower viscosity than the untreated vegetable oil and can be used as a substitute for diesel fuel due to its physical properties. Depending on the type of plant used, the esters formed are partially mono- to polyunsaturated, which leads to a reduced oxidation stability.
Biodiesel kann in reiner Form angewendet werden, aber auch dem fossilen Diesel beigemischt werden.biodiesel can be used in pure form, but also the fossil diesel be mixed.
Wie bereits oben erwähnt, müssen den Kraftstoffen nunmehr Additive zugegeben werden, die die Oxidationsstabilität verbessern. Im Gegensatz zu Öladditiven müssen Kraftstoffadditive aschefrei sein, d. h., es dürfen keine metallhaltigen Verbindungen und/oder Salze eingesetzt werden. Ansonsten würden sich bei der Verbrennung Ablagerungen im Motorraum bilden. Ferner muss in Kraftstoffen im Gegensatz zu Motorölen auf den Einsatz von schwefelhaltigen Additiven verzichtet werden.As already mentioned above, need the fuels now additives are added, the oxidation stability improve. Unlike oil additives need Fuel additives are ashless, d. h., no metal-containing compounds and / or salts are used. Otherwise During combustion, deposits would build up in the engine compartment form. Furthermore, in fuels unlike engine oils dispensed with the use of sulfur-containing additives.

Kraftstofffilter sind notwendige Komponenten, die verwendet werden, um Verbrennungsmotoren durch das Herausfiltern von Verunreinigungen zu schützen und dadurch eine Beschädigung des Motors und anderer stromabwärtigen Komponenten, wie Ventile, Kraftstoffeinspritzeinrichtungen, Kraftstoffleitungen und damit zusammenhängender Komponenten zu verhindern. Kraftstoff kann eine große Vielzahl von Verunreinigungen aus einer Reihe von Quellen mitreißen. So kann Kraftstoff oxidieren und harzartige Ablagerungen bilden. In Kraftstoffen mit erhöhter Wasserlöslichkeit können auch Bakterien wachsen, die einen „Schleim" auf den Innenflächen von Kraftstofftanks, Kraftstoffleitungen und Kraftstofffiltern bilden, wodurch diese blockieren können.Fuel filter are necessary components that are used to internal combustion engines by filtering out contaminants and thereby damaging the engine and other downstream ones Components, such as valves, fuel injectors, fuel lines and related components. Fuel can be a great variety of contaminants get carried away from a number of sources. That's how fuel works oxidize and form resinous deposits. In fuels with increased water solubility can also Bacteria grow that have a "mucus" on the inner surfaces of fuel tanks, fuel lines and fuel filters, which can block them.
Glücklicherweise kann die Bildung solcher harzartigen Materialien und von Bakterien durch Zugabe von Kraftstoffzusätzen wie Antioxidanzien und Bioziden zum Kraftstoff gehemmt werden. Damit die Zusätze wirksam sind, müssen sie konstant im Kraftstoff vorhanden sein. Es sind daher Kraft stofffilter zur Verwendung mit Verbrennungsmotoren bekannt, die ein Kraftstoffadditiv beinhalten.Fortunately can the formation of such resinous materials and bacteria by adding fuel additives such as antioxidants and biocides to fuel are inhibited. So that the additives are effective, they must be constantly present in the fuel be. There are therefore fuel filters for use with internal combustion engines known, which include a fuel additive.

Aufbau des erfindungsgemäßen Filterelements zeigt
Die immobilisierten Antioxidanzien werden daher so in einer Lage eines mehrlagigen Filterelements in der Art angeordnet, dass im Fluid vorhandene Schadstoffe chemisch oder physikalisch zersetzt oder gebunden werden. Sie können auch chemisch an eine Imprägnierung des Filterelements angebunden werden. Bei der Imprägnierung kann es sich bspw. um ein Phenolharz handeln.The immobilized antioxidants are therefore in a position of one multilayer filter element arranged in the manner that in the fluid existing pollutants decomposed chemically or physically or be bound. You can also chemically attach to an impregnation be attached to the filter element. In the impregnation it may, for example, be a phenolic resin.
