High-cleanness environment-friendly alcohol ether fuel for car

Abstract

The invention provides a high-cleanliness environment-friendly alcohol ether fuel for a car. The fuel provided by the invention consists of the following raw materials: 600-800 parts of methanol, ethanol or a mixture of methanol and ethanol, 100-350 parts of an ether stabilizer, 1-6 parts of an anti-oxygen and anti-gum inhibitor, 2-5 parts of a metal deactivator, 1-3 parts of a corrosion inhibitor, 1-40 parts of a catalytic combustion improver, 2-4 parts of an antistatic agent, 10-100 parts of an antiknock stabilizer, 1-6 parts pf a purification dispersant, 1-6 parts of an anti-wear repair agent, 1-6 parts of a metal corrosion inhibitor, 2-6 parts of a rubber and plastic part corrosion and swelling inhibitor, 10-50 parts of a modified alcohol cosolvent, 0.2-0.8 part of a bactericide and 0.04-0.1 part of a recognition agent. The fuel provided by the invention has the advantages of stable performance, strong power, sufficient combustion, good seismic performance, good acceleration, easiness for starting up, no air lock, no separated layer, reduced fuel consumption, cleaner tail gas emission and no need of changing the structure of a spark ignition engine in the prior art and can be separately used, used instead of regular gasoline or used together with regular gasoline by co-combustion.

Description

technical field [0001] The invention relates to a liquid fuel for vehicles, in particular to a high-definition and environment-friendly alcohol-ether fuel for vehicles with methanol, ethanol or mixed alcohol as the main raw material. Background technique [0002] In today's world, energy and the environment are the main factors affecting the sustainable development of the global economy and society, and energy is the material basis for human survival and economic development. However, with the continuous and high-speed development of the world economy, problems such as energy shortage, environmental pollution, and ecological deterioration have become more and more prominent. According to expert predictions, according to the current consumption, oil and natural gas can only last for less than half a century at most, and coal can only last for one or two hundred years. Therefore, no matter what kind of conventional energy structure, the energy crisis facing mankind is becoming...

Problems solved by technology

[0017] But the weak point of this additive is: 1. preferred ether compound isopropyl ether raw material in the component is limited, if used alone in large quantities, there is a big problem of gap, and this raw material is not effective in low temperature or cold region engine cold start ; 2) the cost of isoheptanol in the components is high, the solubilizing effect is not ideal, the dosage is large, and the output is limited; 3) the selected imidazole derivative benzotriazole has good solubility in polar solvents, and is particularly suitable for metals. Non-ferrous metals have good corrosion inhibition effect, but their solubility in non-polar solvents is poor, and the corrosion inhibition effect on other metals is not ideal

[0019] However, the alcohol ether fuel relies on more petroleum product raw materials, which hinders the development of long-term alternative fuels, because petroleum product raw materials will become less and less as time goes on, and at the same time, the engine starts when the fuel is at -30°C in cold regions The time is longer, the fuel consumption increases, the best clean emission cannot be achieved in the exhaust emission, and the effect on engine anti-wear, repair and lubrication is not very good
