Problems solved by technology

[0004] In order to solve these problems, people have designed a variety of alcohol-based gasoline, but due to the immaturity of technology, although there are many alcohol-based gasoline, there are also many problems, the most important one is the problem of water content. Strictly control it at about 0.5%, otherwise the performance will be unstable and phase separation will easily occur; in addition, the power attenuation problem of alcohol-based gasoline cannot be ignored
In addition, in the prior art, the alcohol-based fuel is mainl

Abstract

The invention relates to the technical field of fuels, and particularly relates to low-emission vehicle fuel. The low-emission vehicle fuel is prepared though the following raw materials in parts by weight: 25-50 parts of monohydric alcohol, 20-35 parts of normal octane, 10-20 parts of ethyl levulinate, 2-8 parts of 1-trityl-1H-imidazole, 1-3 parts of a clearing agent, and 0.5-2.3 parts of an combustion improver, wherein the monohydric alcohol is one or two of methyl alcohol, amyl alcohol and isobutyl alcohol; the clearing agent is the mixture of 2-methylimidazole and butyl cellosolve; the combustion improver is the mixture of dimethyl carbonate and ethyl tert butyl ether. The low-emission vehicle fuel is high in exhaust gas emission and can directly replace gasoline on the premise that an engine remains and low exhaust gas emission is ensured.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to low-emission vehicle fuel. Background technique [0002] At present, motor vehicle exhaust emissions have become the main source of pollution in major cities around the world. Compared with gasoline vehicles, gasoline vehicles pollute the environment more seriously, and more and more vehicles and various internal combustion engines use gasoline as fuel. Due to the high carbon content of gasoline, the oxygen in the air can only be used as an antioxidant during the combustion process and cannot be completely burned, so a large amount of black smoke is emitted, resulting in increased fuel consumption, wasting resources and polluting the environment. [0003] In order to solve the problem of the depletion of petroleum energy, alcohol-based fuel, as an alternative fuel with wild gas and fuel oil, has become the most potential new alternative renewable energy.
