Abstract

Diesel fuels comprise (at least mainly) an alcohol, pref. ethanol, and an ignition accelerator (I), pref. a lower alkyl (esp. ethyl) nitrate or nitrite. The fuel pref. contains 3-4 vol.% of (I) in the case of ethyl nitrate or nitrite. The latter can be produced from ethanol using saltpetre as N source. Both the alcohol and (I) can be produced from inexpensive vegetable raw materials (sugar cane, manoic, etc.). The fuels are stable homogeneous mixts.

Description

Dieselkraftstoff Diesel fuel

Dio Erfindung betrifft ein Kraftstoffgemisch fiir Diesolmotoren.The invention relates to a fuel mixture for diesel engines.

In Ländern mit intensivem Anbau von Zuckerrohr, Maniok u. ä.In countries with intensive cultivation of sugar cane, cassava and the like.

für die Äthylalkoholherstellung geeigneten pflanzlichen Rohstoffen ist eine Verwendung von Äthanol als Ersatz von Dieselkraftstoff zur Verbrennung im Diesolmotor von größtem Interesse. Äthanol ist aber ein fiir die Selbstzündung iii Dioselmotoren ungeeigneter Kraftstoff, weil er zündunwillig ist.Vegetable raw materials suitable for the production of ethyl alcohol is a use of ethanol as a substitute for diesel fuel for combustion of the greatest interest in the diesel engine. Ethanol, however, is suitable for spontaneous ignition iii Diosel engines unsuitable fuel because it does not ignite.

Zwar ist es bekannt, durch Erhöhung der Vordichtungsen<lternperatur auch weniger zündwillige Kraftstoffe z. n. Alkohol in Dieselmotoren zu verarbeiten. Die Verdichtungsendtemperatur kann z. B. mittels Ansaugluftvorwärmung oder durch Wahl eines höheren Verdichtungsverhältnisses erhöht werden.It is known to increase the pre-sealing temperature also less ignitable fuels z. n. Process alcohol in diesel engines. The compression end temperature can, for. B. by means of intake air preheating or by Choosing a higher compression ratio can be increased.

Es ist ferner bekannt, daß Dieselmotoren dann - teilweise -mit Alkohol betrieben werden können, wonn der Ansaugluft des Dieselmotors nach dem Vorbild eines Vergasermotors Äthanol zugemischt wird und eine kleine in don Zylinder eingespritzte Dieselkraftstoffmenge für die Zündung des stark verdichteten Gemisches soret (Ziindstrahlprinzip).It is also known that diesel engines then - partially - with alcohol can be operated, wonn the intake air of the diesel engine on the model of a Carburetor engine's ethanol is mixed in and a small one is injected into the cylinder Diesel fuel quantity for the ignition of the highly compressed mixture soret (pilot jet principle).

Es ist ferner bekannt, daß zündunwillige Kraftstoffe auf Mineralölbasis durch Zumischen von zündwilligen Brennstoffen für die Verbrennung im Dieselmotor geeignet gemacht werden können. Es wäre daher naheliegend, dem zu verbrennenden Athanol Dieselkraftstoff zuzumischen, um ein selbstzündwilliges Kraftstoffgemisch zu erhalten. Dies ist jedoch nicht möglich, da Äthanol und Dieselkraftstoff niclit dauerhaft mischbar sind.It is also known that non-ignitable fuels based on mineral oil by adding ignitable fuels for combustion in the diesel engine can be made suitable. It would therefore be obvious to choose the one to be burned Add ethanol to diesel fuel to create a self-igniting fuel mixture to obtain. However, this is not possible because ethanol and diesel fuel are not used are permanently miscible.

Es ist ferner bekannt, Dieselkraftstoffe auf Mineralölbasis, deren Selbstzündwilligkeit für den Betrieb im Dieselmotor nicht ausreicht, durch Zumischung von Zündbeschleunigern in ihrer Zündwilligkeit zu erhöhen, so daß sie insgesamt die für den Betrieb im Dioselmotor ausreichende Selbstzündwilligkeit erreichen. Ein bekannter Zündbeschleuniger dieser Art enthält in der Hauptsache Amylnitrat sowic noch einige andere Zusätze, die Erdölderivate siiid. Nachteilig daran ist die Abhängigkeit von Erdöleinfuhren.It is also known, diesel fuels based on mineral oil, their Self-ignition is not sufficient for operation in a diesel engine due to admixture of ignition accelerators to increase their ignitability, so that they overall achieve sufficient spontaneous ignition for operation in a Diosel engine. A known ignition accelerator of this type contains mainly amyl nitrate as well as some other additives which are petroleum derivatives. The disadvantage is the dependence on oil imports.

Aufgabe dor Erfindung ist es, die Möglichkeit aufzuzeigen, wie Alkohol in Dieselmotoren als Kraftstoff verarbeitot werden kann, ohne von Erdölprodukten abhängig zu sein.The object of the invention is to show the possibility of how alcohol Can be processed as fuel in diesel engines without using petroleum products to be dependent.

Zur Lösuilt dieser Aufgabe wird orfindungsgemäß eiii Zündbeschleuniger vorwondet, dor aus Nitrat und/oder Nitrit von Alkohol besteht bzw. enthält. Grundsätzlich ist hierbei jeder Alkohol, der boi der nlkoholiscllon Gärung anfällt, geeignet, also Äthylalkohol, Propylalkohol, Butylalkohol oder Amylalkohol. Die Nitrate und Nitrite dieser Alkohole lassen sich ohne weiteres dauerhaft mit Alkoliol, insbesondere mit Äthylalkohol mischen. Ferner schaffen diese Ausgangsstoffe keine Rohstoffprobleme. Die aufgezählten Alkohol-bzw. Nitrat- und Nitritverbindungen unterscheiden sich im wesentlichen durch die Länge ihrer Alkoholkette. Äthylalkohol ist kurzkettig und Amylalkollol ist langkettig. Vortoilhafterweise wird als Zündbeschleuniger Äthylnitrat bzw.According to the invention, an ignition accelerator is used to solve this problem vorwondet, which consists of nitrate and / or nitrite of alcohol or contains. Basically Any alcohol that accrues during alcoholic fermentation is suitable for this, i.e. ethyl alcohol, propyl alcohol, butyl alcohol or amyl alcohol. The nitrates and Nitrites of these alcohols can easily be used permanently Mix alcohol, especially with ethyl alcohol. Furthermore, these create raw materials no raw material problems. The listed alcohol or. Nitrate and nitrite compounds differ essentially in the length of their alcohol chain. Ethyl alcohol is short chain and amyl alcohol is long chain. Advantageously, it is used as an ignition accelerator Ethyl nitrate resp.

-nitrit verwendet, weil bei der Verwendung dieses Stoffes als Zündbeschleuniger diosor lediglich in einer Menge von drei bis vier Prozent zu Alkohol als Kraftstoff zugesetzt zu werden braucht. Von dem besonders langkettigen Amylnitrit bzw. -nitrat als Zündbeschleuniger müßte demgegenüber eine wesentlich größere Menge, nimlich otwa fiinfzehn 1>rozont zu dom Alkohol als Kraftstoff zugegeben werden, um die erforderliche Selbstzündwilligkeit zu erreichen. Die Mischungsverhältnisse für die Nitrat- bzw. Nitritverbindungen der dazwischen liegenden Alkohole liegen etwa zwischon diesen Werten. Je kurzer also die Alkoholkette dos Nitrates bzw. Nitrites ist, mit um so weniger Zündbeschleuniger kann also die erforderliche Selbstzündwilligkeit des Alkohols erreicht werden.-nitrite used because when using this substance as an ignition accelerator diosor only in an amount of three to four percent to alcohol as fuel needs to be added. From the particularly long-chain amyl nitrite or nitrate as an ignition accelerator, on the other hand, a much larger amount would have to be used, namely otwa fifteen 1> rozont to dom alcohol to be added as fuel to the to achieve the required spontaneous combustion. The mixing ratios for the Nitrate or nitrite compounds of the alcohols in between are roughly in between these values. The shorter the alcohol chain dos Nitrates or Nitrites, with the less ignition accelerator can therefore achieve the required self-ignition of alcohol can be achieved.

Als ein Beispiel für ein Kraftstoffgemisch für Dieselmotoren mit ausreichend hoher Selbstzündwilligkeit seien folgende Werte angegeben: 97 Volumenprozent Äthylalkohol und 3 Volumenprozent Äthylnitrat (C2H5ONO2). Die beiden Stoffe lassen sich ohne weiteres dauerhaft und homogen vermischen.As an example of a fuel mixture for diesel engines with sufficient The following values are given for high spontaneous ignition: 97 percent by volume of ethyl alcohol and 3 percent by volume ethyl nitrate (C2H5ONO2). Both fabrics can be used without Mix more permanently and homogeneously.

ohne daß die gebildete Mischung sich wieder entmischen wisrde und ohne daß die Mischungspartner miteinander reagieren würden.without the mixture formed being able to separate again and without the mixing partners reacting with one another.

Bei der Einspritzung eines solchen flüssigen Kraftstoffes in die hochkomprimierte und entsprochend hocherhitzte Verbrennungsluft eines Dieselmotors entzündet sich der eingespritzte Kraftstoffstrahl an der ihn umeebender, heißen verdichteten Luft.When injecting such a liquid fuel into the highly compressed and the correspondingly highly heated combustion air of a diesel engine ignites the injected fuel jet in the hot, compressed air surrounding it.

Der Zündbesclllouniger kann ohne weiteres aus technischem Alkohol unter Zugabe von Salpeter als Stickstoffquelle gewonnen werden; es sind nur sehr geringe Mengen von Salpeter erforderlich. Da technischer Alkohol ein Gemisch verschiedener Alkohole darstellt, bildet der so gewonnene Zündbeschleuniger ein Gemisch aus Nitraten bzw. Nitriten verschiedener Alkohole . Dies ist ohne weiteres zulässig.The Zündbesclllouniger can easily from technical alcohol obtained by adding saltpeter as a nitrogen source; it's just very small amounts of saltpetre required. As technical alcohol is a mixture of different Represents alcohols, the ignition accelerator obtained in this way forms a mixture of nitrates or nitrites of various alcohols. This is easily permissible.
