Problems solved by technology

[0002] Diesel has always been a fuel that is in short supply in my country, especially in winter and busy farming seasons. In order to solve the problem of diesel shortage, many methanol diesels have appeared. There is still an obvious gap with the problem of water phase separation, especially the problem of short shelf life has not reached the level of commercial application; at the same time, there is still a problem that the physical and chemical performance indicators of methanol diesel formulated with various additives are still not enough. Fully meet the engine, especially the physical and chemical performance indicators of vehicle diesel is even more gap

Abstract

The invention provides an alcohol-based diesel oil fuel which comprises the following components by the weight percentage: 50% to 70% of diesel oil, 18% to 32% of methanol, and 10% to 25% of additives. The diesel oil fuel is characterized in that since water is generated after the combustion of alcohol-base, the hazardous material emission in tail gas is reduced; the defect that the methanol cetane number is short is improved by the additive; and under the condition of low temperature or long-time storage, no phase separation is generated, the product is transparent and stable, and the water-resistant characteristic is good. The additive can be combined with international gasoline of any label, therefore, an engine does not need refitting or changing while using the alcohol-based diesel oil fuel.

Description

technical field [0001] The invention relates to the field of fuel, in particular to a blended alcohol-based diesel fuel. Background technique [0002] Diesel has always been a fuel that is in short supply in my country, especially in winter and busy farming seasons. In order to solve the problem of diesel shortage, many methanol diesels have appeared. There is still an obvious gap with the problem of water phase separation, especially the problem of short shelf life has not reached the level of commercial application; at the same time, there is still a problem that the physical and chemical performance indicators of methanol diesel formulated with various additives are still not enough. There is a gap in the physical and chemical performance indicators of diesel oil used in engines, especially for vehicles. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an alcohol-...
