Description

Die Erfindung betrifft eine Kraftstoffvorwärmanlage für Dieselmotoren zur Betreibung mit Pflanzenöl und zum Einbau in alle gängigen Dieselkraftwagen, dargelegt im einteiligen Patentanspruch 1.The The invention relates to a fuel preheating system for diesel engines for operation with vegetable oil and for installation in all common Diesel cars set forth in the one-part patent claim 1.

Es ist bekannt, dass die Erdölressourcen bald erschöpft sind und die Umwelt stark belastet ist.It is known that the oil resources soon exhausted and the environment is heavily polluted.

In einer Klimazone, in der nicht nur Temperaturen vorherrschen, die eine Leichtläufigkeit des Pflanzenöles ermöglichen, sondern auch Minustemperaturen vorhanden sind, ist das one-fuel-System mit einem gewissen Aufwand verbunden. Es existiert ein one-fuel-System, bei dem ab gewissen Temperaturen Diesel hinzugetankt werden muss. Leider spricht auf Grund der Tatsache, dass eben Dieselkraftstoff ab gewissen Temperaturen hinzugetankt werden muss, die Unpopularität dieser Kraftstoffmöglichkeit kaum Verbraucher an.In a climatic zone in which not only temperatures prevail, the a smoothness of vegetable oil enable, but also minus temperatures are present, is the one-fuel system with connected to a certain effort. There is a one-fuel system where diesel must be added at certain temperatures. Unfortunately, due to the fact that just diesel fuel must be added up from certain temperatures, the unpopularity of this Fuel option hardly any consumers.

Außerdem gibt es ein Zwei-Tank-System, bei dem nach dem Start des Motors (mit Diesel) nach einer gewissen Zeit auf Pflanzenöl umgeschaltet wird. Beim Zwei-Tank-System ist es erforderlich, ständig daran zu denken, dass der Umschalter betätigt wird, was aber unter Umständen schon mal vergessen werden kann.There are also it is a two-tank system in which after starting the engine (with Diesel) is switched to vegetable oil after a certain time. In the two-tank system, it is necessary constantly on it to think that the switch is pressed, but what may already let's forget it.

Das dritte existierende System setzt eine Standheizung voraus, die auch wieder mit Diesel läuft.The third existing system requires a parking heater, which also running again with diesel.

Diese bekannten Systeme erfordern immer den Zusatz von Dieselkraftstoff.These known systems always require the addition of diesel fuel.

Die WO 03/025282 A1 zeigt eine Kraftstoffvorwärmanlage mit externer Pumpe und Edelstahl-Plattenwärmer zur Wärmeübertragung zwischen Kühlwasser und Kraftstoff.The WO 03/025282 A1 shows a fuel preheating system with external pump and stainless steel plate warmer for heat transfer between cooling water and fuel.

Aus der EP 1 233 171 A1 ist eine Kombination eines Spiralwärmetauschers mit einer Glühkerze zur Heizung des Kraftstoffes und mit einem zeitlich justierbaren Relais bekannt.From the EP 1 233 171 A1 is a combination of a spiral heat exchanger with a glow plug for heating the fuel and a time-adjustable relay known.

Isolierte Kraftstoffleitungen an sich sind durchaus bekannt wie die DE 203 00 189 U1 zeigt.Isolated fuel lines are well known as the DE 203 00 189 U1 shows.

Aus der FR 2 783 722 A1 sind ein Plattenwärmetauscher und ein auswaschbares Filter bekannt.From the FR 2 783 722 A1 For example, a plate heat exchanger and a washable filter are known.

Die FR 2 549 148 A1 lehrt den Fachmann die Zusammenfassung einer elektrischen Heizung mit einem Kühlwasser/Kraftstoff-Wärmetauscher und mit einem Filter in einem Gehäuse.The FR 2 549 148 A1 teaches a person skilled in the art the summary of an electric heater with a cooling water / fuel heat exchanger and with a filter in a housing.

Aufgabe der Erfindung ist es, einen von der Umgebungstemperatur unabhängigen Betrieb von Dieselfahrzeugen mit Pflanzenöl als einzigem Kraftstoff zu ermöglichen.task The invention is an independent of the ambient temperature operation of diesel vehicles with vegetable oil as the only fuel too enable.

Diese Aufgabe wird durch eine Kraftstoffvorwärmanlage mit den Merkmalen des Anspruches 1 gelöst.These Task is by a fuel preheater with the features of claim 1 solved.

Um ökologisch Auto fahren zu können, können durch dieses one-fuel-System die Ressourcen wie Raps-, Soja- und Frittieröl genutzt werden. Die Erfindung zielt auf umweltgerechte Verbrennung hin, sowie auf ein Umdenken auf andere natürliche, nachwachsende Energiequellen.To ecological To drive a car, can through this one-fuel system, the resources such as rapeseed, soy and cooking oil be used. The invention aims at environmentally friendly combustion and a rethinking of other natural, renewable energy sources.

Der Schadstoffausstoß und die Russbelastung sind massiv minimiert.Of the Pollutant emissions and the soot load is massively minimized.

Mit der erfindungsgemäßen Kraftstoffvorwärmanlage umgeht man das Nachtanken von Dieselkraftstoff für das Starten des Motors. Der Einbau einer Standheizung ist nicht nötig.With the fuel preheating system according to the invention bypasses the refueling of diesel fuel for starting the engine. Of the Installation of a heater is not necessary.

Die verstärkte 12-Volt-Kraftstoffpumpe hilft die Förderung von gelartigem Kraftstoff zu realisieren. Dieses ist erforderlich, da die werkseitig montierten Pumpen eine zu geringe Förderleistung haben.The increased 12 volt fuel pump helps to promote gelatinous fuel to realize. This is required because the factory assembled Pumps too low flow rate to have.

Es ist wünschenswert einen großdimensionierten Feinfilter zu verbauen, der auswaschbar sein muss, um eventuellen Experimenten der Besitzer der Fahrzeuge vorzubeugen (ungereinigtes Speiseöl).It is desirable a large-sized To install fine filters, which must be able to be washed out, if necessary To prevent experiments of owners of vehicles (uncleaned Cooking oil).

Der Wärmetauscher (Kit) ist in der Funktion wie ein Durchlauferhitzer zu sehen, der mit der Wärmeenergie des Motors den Treibstoff vorheizt, um eine adäquate Viskosität zu erreichen. Hierzu ist eine Temperatur von nur 12°C erforderlich. Der Wärmetauscher (Kit) wird an das Kühlsystem des Motors angeschlossen. Der Kit selber ist ein simples isoliertes Metallgehäuse mit einer Heizspirale, durch das der Kraftstoff läuft.Of the heat exchangers (Kit) is seen in the function as a water heater, the with the heat energy the engine preheats the fuel to achieve an adequate viscosity. This requires a temperature of only 12 ° C. The heat exchanger (Kit) is connected to the cooling system connected to the engine. The kit itself is a simple insulated metal case with a heating coil through which the fuel runs.

Es wird ein Großkraftstofffilter in dem Fahrzeug verbaut, der mit einer Vorglühkerze ausgerüstet ist. Die Vorglühkerze ist an die Vorglühautomatik des Motors angeschlossen, um den Kraftstoff für das Startendes Motors vorzuwärmen. Des weiteren ist dieser Filter mit einer Handpumpe ausgerüstet, um im Falle einer Havarie die Luft aus dem Treibstoffsystem zubekommen.It becomes a large fuel filter installed in the vehicle equipped with a pre-glowing candle. The pre-glow candle is to the preheat automatic connected to the engine to preheat the fuel for starting the engine. Of Further, this filter is equipped with a hand pump to work in the In case of an accident, the air from the fuel system zubekommen.

Es müssen längere Glühkerzen verbaut werden, um eine höhere Motorvorheizung zu realisieren. Man erreicht dadurch eine höhere Flammfläche. Stärkere Kabel und Brücken sind erforderlich, um eine Überlastung der Vorglühanlage auszuschließen.It have to longer glow plugs be built to a higher To realize engine pre-heating. This achieves a higher flame area. Stronger cables and bridges are required to overload the glow plug system excluded.

Das zeitlich justierbare Vorglührelais ist für den Kit notwendig, um dieses Relais in allen Fahrzeugen und Hubraumklassen einsetzen zu können und auf das jeweilige Fahrzeug abzustimmen.The time-adjustable preheating relay is necessary for the kit to relay this in all driving be able to testify and use displacement classes and to vote for the respective vehicle.

Die isolierten Kraftstoffleitungen sollten unbedingt verbaut werden, um einen Wärmeverlust des Treibstoffs, soweit physikalisch möglich, auszuschließen. Die Kraftstoffpumpen arbeiten mit mind. 100% Überschuss, um den im Tank befindlichen Treibstoff vorzuwärmen.The insulated fuel pipes should be installed, for a heat loss of the fuel, as far as physically possible exclude. The Fuel pumps work with at least 100% excess to that in the tank Preheat fuel.

Da Speiseöl im Minustemperaturbereich stark ausflockt und auch durch eine stärkere Pumpe nicht in den Verbrennungskreislauf einbezogen werden kann, muss der Tank eine Temperatur von mindestens 5°C haben. Aus diesem Grund wird die Unterseite des Tanks mit einer 12-Volt-Heizmatte besetzt. Um Wärmeverluste zu vermeiden wird der Tank anschließend komplett mit Dämmmaterial umschlagen. Um einen externen Energieanschluss zu vermeiden, während der Ruhephasen, sollte eine zweite Batterie, die nur an den Kit angeschlossen wird, sowie eventuell eine stärkere Lichtmaschine eingebaut werden.There cooking oil Strong flocculation in the minus temperature range and not even by a stronger pump can be included in the combustion cycle, the tank must a temperature of at least 5 ° C to have. For this reason, the bottom of the tank with a 12 volt heating mat occupied. To heat loss to avoid the tank is then complete with insulation folding. To avoid an external power connection while the Rest periods, a second battery should be connected only to the kit will, as well as possibly a stronger one Alternator be installed.
