Multifunctional alcohol-based fuel

Abstract

The invention belongs to the technical field of fuels, and particularly relates to a multifunctional alcohol-based fuel. The multifunctional alcohol-based fuel is prepared from the following raw materials in parts by weight: 68 to 92 parts of methyl alcohol, 16 to 34 parts of diesel oil, 0.7 to 1.9 parts of amyl nitrate, 0.2 to 1.4 parts of poly-methoxyl dimethyl ether, 0.02 to 0.14 part of 5-amino-o-cresol, 0.3 to 1.5 parts of N-methylaniline, 0.1 to 1.3 parts of ferricinium, 0.01 to 0.07 part of tetrahydrocyclopentadiene, 0.03 to 0.15 part of isoamyl alcohol and 0.1 to 1.3 parts of a clearing agent. The multifunctional alcohol-based fuel disclosed by the invention has various functions of cleaning, oxidization prevention, combustion supporting, corrosion resisting, freezing resisting, smoke elimination and increase of a cetane number.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a multifunctional alcohol-based fuel. Background technique [0002] With the depletion of petroleum resources, people are trying to find its substitutes. Methanol is regarded as the potential preferred liquid fuel to replace gasoline and diesel because of its cleanliness, high calorific value, high efficiency and easy availability. Some countries have used it as a practical liquid fuel for vehicles. There are many examples of using methanol as a substitute for diesel in China. As a diesel substitute, it is being explored. The main problems of methanol used as vehicle engine fuel: [0003] One is that the power performance of methanol fuel is lower than that of diesel; the other is that the cetane number is low, only 2 to 3, and the cetane number of the diesel engine cannot be less than 45 when it is compressed and started; [0004] The third is that methanol has a swelling and...

AI Technical Summary

Problems solved by technology

[0003] One is that the power performance of methanol fuel is lower than that of diesel; the other is that the cetane number is low, only 2 to 3, and the cetane number of the diesel engine cannot be less than 45 when it is compressed and started;

[0004] The third is that methanol has a swelling and corrosion effect on non-metallic parts of the engine system, while there is a potential corrosion problem on metal parts;

[0005] The fourth is that the viscosity coefficient of methanol is small, so it has a certain flushing effect on the engine system;

[0006] The fifth is the compatibility between methanol and diesel oil, which will separate when it meets water, and the storage stability is poor

But some existing methanol fuel additives can improve the combustion performance of fuel in internal combustion engines to a certain extent, but can cause internal combustion engines to get rusty, carbon deposits are serious, greatly reduce the normal operation of internal combustion engines, and pollute the environment equally; Environmental pollution, but it can not improve the combustion efficiency of fuel in the internal combustion engine, resulting in increased fuel consumption; some can improve the combustion efficiency of fuel in the internal combustion engine and improve environmental pollution, but the effect is not very ideal. Moreover, the cost of raw materials used is relatively high, and the production process is relatively complicated.
