Description

Die Neuerung betrifft Dieselmotoren, die ohne Umbaumaßnahmen mit Dieselkraftstoff betrieben werden können .The innovation affects diesel engines, the without remodeling can be operated with diesel fuel.

Durch die Neuerung kann der Betrieb des Motors mit Naturöl ohne Eingriff und Umbau in Motorengeometrie, Einspritzpumpe und Einspritzdüsen ermöglicht werden.With the innovation, the company can the engine with natural oil without intervention and modification in engine geometry, injection pump and injectors allows become.

Durch den Betrieb von Dieselmotoren mit Naturöl ergeben sich Vorteile für Wirtschaft und Umwelt. Hier einige Vorzüge.By operating diesel engines with natural oil there are advantages for Economy and environment. Here are some advantages.

  • a) Ausgeglichenen CO² Bilanza) Balanced CO² balance
  • b) Keine Gewässergefährdungb) No water hazard
  • c) Stärkung der heimischen Landwirtschaft, die Raps als Ölfrucht anbauen und verwerten kannc) Strengthening domestic agriculture, which cultivate and utilize rapeseed as an oil crop can
  • d) Unabhängiger von Rohöleinfuhrend) Independent of crude oil imports

Da Naturöl oder tierische Fette eine höhere Viskosität aufweisen als Dieselkraftstoff, muss entweder der Motor diesen Kraftstoffen angepasst oder der Kraftstoff wird so aufbereitet, das der Motor ohne Schaden zu nehmen, betrieben werden kann. Da eine Anpassung des Motors auf den Kraftstoff wirtschaftlich nicht sehr erfolgreich war ( Motor der Firma Elsbeth ) sollte der Kraftstoff so aufbereitet werden, das ein Serienmotor damit betrieben werden kann. Eine Möglichkeit stellt die Umesterung von Rapsöl dar. Der unter Biodiesel vertriebene Kraftstoff ist im vergleich zu unbehandeltem Rapsöl teuer und energieaufwendig herzustellen. Außerdem ist Biodiesel giftig.Because natural oil or animal fats are one higher viscosity have as diesel fuel, either the engine must use these fuels adjusted or the fuel is processed so that the engine can be operated without being damaged. Because an adjustment of the engine on the fuel economically not very successful was (engine of the Elsbeth company) the fuel should be processed in this way that a series engine can be operated with it. A possibility represents the transesterification of rapeseed oil The fuel sold under biodiesel is in comparison to untreated rapeseed oil expensive and energy consuming to manufacture. Biodiesel is also toxic.

Serienmotoren können durch die neue Kraftstoffaufbereitung mit geringem Aufwand umgerüstet werden.Series engines can with the new fuel preparation converted with little effort become.

Die Neuerung ist für den Fahrer eines mit der Neuerung ausgestatteten Motors problemlos. Der Betrieb mit Diesel ist weiterhin möglich.The innovation is for the driver of an engine equipped with the innovation without problems. The operation with diesel is still possible.

Manuelle Umstellungen auf zündwillige Kraftstoffe vor dem Abstellen des Motors entfallen.Manual changes to ignitable No fuel is needed before the engine is switched off.

Der als Stand der Technik in diesem Bereich praktizierte Einbau eines zweiten Kraftstofftankes, der mit zündwilligem Kraftstof gefüllt ist und das Starten des Motors sowie die Heizung des Öles übernimmt, entfällt. Auch die manuelle Regelung ( Umschaltung ) zwischen den Tanks vor dem Abstellen des Motors entfällt. Wird das Umschalten der Kraftstoffzufuhr auf zündwilligeren Kraftstoff vor dem Abstellen des Motors vergessen, kann es zu Startschwierigkeiten kommen. Da beim Abstellen dem Motor zündunwilliges Naturöl in der Einspritzanlage verbleibt und nicht vorgeheizt werden kann.The state of the art in this Practiced installation of a second fuel tank, the with ignitable Filled with fuel and starts the engine and heats the oil, eliminated. Also manual control (switching) between the tanks before Stopping the engine is not necessary. Will switch the fuel supply to more ignitable fuel before forgetting to switch off the engine can cause starting problems come. Because when the engine is switched off, natural oil in the Injection system remains and cannot be preheated.

Unter Naturöl versteht der Anmelder alle Öle, die von natürlichen Pflanzen gewonnen werden sowie tierische Fette. Zum Beispiel Rapsöl, Sonnenblumenöl oder Öl von Nüssen.The applicant understands natural oil as all oils that of natural Plants are extracted as well as animal fats. For example, rapeseed oil, sunflower oil or oil from nuts.

Nachstehend wird die Neuerung anhand der als Anlage 1 bezeichneten Zeichnung der Kraftstoffaufbereitung mit Einspritzpumpe und Einspritzdüsen, näher erläutert.The innovation is shown below as an attachment 1 designated drawing of the fuel preparation with injection pump and injection nozzles, explained in more detail.

Der Kraftstoff wird mit der Förderpumpe, die jeder Serienmotor besitzt, durch die mit Begleitheizung und Wärmedämmung ausgerüstete Kraftstoffleitung ( 1 ) zur Vorheizung ( 2 ) befördert. Eine Begleitheizung und Wärmedämmung der Kraftstoffleitung ist nur dann erforderlich, wenn beabsichtigt ist, ganzjährig, auch bei niedrigen Temperaturen den Motor mit Naturöl zu betreiben.The fuel is supplied with the feed pump, which every series engine has, through the fuel line equipped with heat tracing and thermal insulation ( 1 ) for preheating ( 2 ) promoted. A trace heating and thermal insulation of the fuel line is only necessary if the intention is to operate the engine with natural oil all year round, even at low temperatures.

Mit dem Druckregulierer ( 3 ) kann der Druck auf die Einspritzpumpe eingestellt werden. Der Kraftstoff fließt dann durch die Vorheizung ( 2 ) und wird dabei durch elektrische Heizelemente oder einen Wärmetauscher ( 4 ), der durch die Abwärme des Kühlwassers gespeist wird, erwärmt. Das Naturöl, das nun auf die für den Motor brauchbare Temperatur erwärmt wurde, fließt nun durch den Kraftstoffilter ( 5 ) in die Einspritzpumpe und wird über die Einspritzdüsen dem Motor zugeführt. Durch den Druckregler ( 3 ) wird nur soviel Kraftstoff dem Motor zugeführt, wie dieser zum Betrieb benötigt. Dadurch wird verhindert, das der gesamte Kraftstoff, der von der Förderpumpe gefördert wird, erhitzt werden muss. Das Naturöl im Kraftstofffilter ( 5 ) wird durch Heizelemente ( 6 ) ständig auf der für den Motor notwendigen Temperatur gehalten. Die Wärmedämmung des Kraftstofffilters ( 7 ) begrenzt die Auskühlung und damit die benötigte Heizenergie.With the pressure regulator ( 3 ) the pressure on the injection pump can be adjusted. The fuel then flows through the preheater ( 2 ) and is thereby replaced by electrical heating elements or a heat exchanger ( 4 ), which is fed by the waste heat of the cooling water. The natural oil, which has now been heated to the temperature that is suitable for the engine, now flows through the fuel filter ( 5 ) into the injection pump and is fed to the engine via the injection nozzles. Through the pressure regulator ( 3 ) only as much fuel is supplied to the engine as it needs to run. This prevents all the fuel that is delivered by the feed pump from having to be heated. The natural oil in the fuel filter ( 5 ) is replaced by heating elements ( 6 ) constantly kept at the temperature necessary for the motor. The thermal insulation of the fuel filter ( 7 ) limits cooling and thus the required heating energy.

Vor dem starten des Motors wird mittels einer elektrisch betriebenen Förderpumpe ( 8 ) das erhitzte Naturöl durch die Einspritzpumpe gespült, um den Motor leichter starten zu können. Der Einsatz dieser Förderpumpe hängt sehr stark vom Motorentyp und der Entfernung des erhitzen Naturöls von der Einspritzpumpe ab.Before starting the engine, an electrically operated feed pump ( 8th ) the heated natural oil is flushed through the injection pump to make it easier to start the engine. The use of this feed pump depends very much on the type of engine and the distance of the heated natural oil from the injection pump.

Mit dem Steuergerät ( 9 ) werden die Ein – und Ausschalttemperaturen der elektrischen Begleitheizung ( 1 ) der Vorheizung ( 4 ) und der ständigen Heizung des Naturöles im Kraftstofffilters ( 6 ) geregelt. Ebenso wird der Betrieb der zusätzlichen Förderpumpe ( 8 ) geregelt.With the control unit ( 9 ) the switch-on and switch-off temperatures of the electrical trace heating ( 1 ) the preheating ( 4 ) and the constant heating of the natural oil in the fuel filter ( 6 ) regulated. The operation of the additional feed pump ( 8th ) regulated.

Die Batterie ( 10 ) speist die Heizelemente mit Strom. Reicht die Batterieleistung der Autobatterie nicht aus, muss eine zusätzliche Batterie ins Fahrzeug eingebaut werden, deren Ladung durch die Lichtmaschine des Motors erfolgt. Auch dies wird vom Steuergerät ( 9 ) geregelt.The battery ( 10 ) feeds the heating elements with electricity. If the battery power of the car battery is not sufficient, an additional battery must be installed in the vehicle, which is charged by the engine's alternator. The control unit ( 9 ) regulated.
