DD271527A1 - FUEL MIXTURE FOR DIESEL FUEL POWER MACHINES - Google Patents

Abstract

The invention relates to a fuel mixture for diesel internal combustion engines. The object of the invention to develop a fuel mixture which has selbstzuendwillige properties without the addition of Zuendbeschleunigern with substantial reduction of Erdoelderivaten is achieved by the mixture of 40 to 60 vol .-% commercial diesel fuel, 30 to 50 vol .-% Rohschwelteer and 10 to 20% by volume of benzene-free wash oil.

Description

Characteristic of the known technical solutions A diesel fuel is known which consists of a mixture of 25% by volume to 75% by volume rapeseed oil (rapeseed oil) and 75% by volume to 25% by volume. Diesel oil exists. Information source: DE-OS 2930220, C 10 L1 / 04. The disadvantage of using vegetable oils is that such a fuel mixture in addition to Zündunwilligkeit

causes incomplete combustion in the combustion chamber. This has coking and after a certain operating time

Resinages on the piston, piston rings and the cylinder liner result, so that with a considerable increase in the Fuel consumption is expected. Furthermore, a composition of alcohols and fatty acid esters is known. This contains 60 b's 90 Vol .-% at least

of a C | -C _e -Alkylest6rs a fatty acid having 12 to 22 carbon atoms containing at least one primary, seKui.uären or tertiary aliphatic monoalcohol having 1 to 5 carbon atoms (in particular methanol, ethanol, 95% ethanol,

Mixtures of butanol / acetone). Information source: DE-OS 315098S, C 10 L1 / 02. The ester components also cause deposits in the combustion chamber, which leads to an increased consumption of the used Fuel would lead. In addition, it is known that alcohols are the autoignition of a fuel mixture

so that the use of ignition accelerators is necessary.

Object of the invention

The aim of the invention is to show a fuel mixture for diesel internal combustion engines, which is suitable as an alternative fuel for operating diesel engines.

Explanation of the essence of the invention

The object of the invention is to develop a fuel mixture for diesel internal combustion engines, which has autoignition properties without the addition of ignition accelerators with substantial reduction of petroleum derivatives. According to the invention the object is achieved in that the mixture of 40 to 60 vol .-%, preferably 50 vol .-%, commercial diesel fuel, from 30 to 50 vol .-%, preferably 40Vol .-%, Rohschwelteer, the high proportion low boiling components and consists of 10 to 20Vol .-%, preferably 10Vol .-%, benzene-free wash oil.

embodiment The invention will be clarified by way of example. The preferred variant of the fuel mixture according to the invention consists of the following components:

- 50 vol .-% of a commercial diesel fuel;

- 40Vol .-% Rohschwelteer, which is obtained in the hydrodynamic fluidized bed smoldering of dried fine-grained lignite coal, and a high proportion of low-boiling component aufwoist;

- 10% benzene-free wash oil.

This composition provides the following advantages:

- Savings of 40 to 50% of diesel fuel, which can be fed to a higher level of refinement;

- restriction of petroleum imports;

- Reduction of the cost of fuel mixture for the same use value compared to conventional diesel fuel.

Claims (1)

Fuel mixture for diesel internal combustion engines, consisting of several miscible components, characterized in that the mixture of 40 to 60 vol .-%, preferably 50 VoI .-%, commercial diesel fuel, from 30 to 50Vol .-%, preferably 40Vol .-%, Rohschwelteer which has a high proportion of low-boiling constituents and consists of 10 to 20% by volume, preferably 10% by volume, of benzene-free wash oil. , Field of application of the invention
