Alcohol-based fuel for diesel engine

Abstract

The invention belongs to the technical field of fuels, and particularly relates to an alcohol-based fuel for a diesel engine. The alcohol-based fuel for the diesel engine is prepared from the following raw materials in parts by weight: 62 to 86 parts of methyl alcohol, 12 to 24 parts of diesel oil, 0.6 to 1.8 parts of amyl nitrate, 0.5 to 1.7 parts of isopropyl ether, 0.4 to 1.6 parts of bicycloheptadiene, 0.3 to 0.9 part of naphthenic acid, 0.1 to 0.7 part of trihexyl phosphate, 0.01 to 0.07 part of dodecyl dimethyl betaine, 0.03 to 0.15 part of antioxidant, and 0.1 to 1.3 parts of clearing agent. The alcohol-based fuel for the diesel engine provided by the invention has the functions of oxidation resistance, combustion supporting, corrosion resistance, dispersion, purification, cetane number improvement and the like, and can directly replace a fuel without the need for modifying an automobile engine.

Description

Technical field [0001] The invention belongs to the field of fuel technology, and particularly relates to an alcohol-based fuel for diesel engines. Background technique [0002] At present, motor vehicle exhaust emissions have become a major source of pollution in major cities in the world. Compared with gasoline vehicles, diesel vehicles have more serious environmental pollution, and more and more vehicles and various internal combustion engines use diesel fuel. Diesel is a hydrocarbon with carbon number between C10 and C22. Due to its high carbon content, only relying on the oxygen in the air as a combustion aid during the combustion process cannot make it completely burnt, so it emits a lot of black smoke, which increases fuel consumption. , Wasting resources and polluting the environment. [0003] With the development of my country's economy and the improvement of people's quality of life, the society's demand for clean energy is increasing, and alcohol-based liquid fuels are...
