Methanol diesel fuel

Abstract

The invention discloses methanol diesel fuel. The methanol diesel fuel comprises the following components in parts by weight: 10 to 30 parts of methanol, 40 to 70 parts of diesel fuel meeting national standard, and 15 to 30 parts of diesel fuel additive; the diesel fuel additive comprises the following components in parts by weight: 5 to 13 parts of diethyl phthalate, 1 to 10 parts of zinc peroxide, 0.01 to 0.03 part of ferrocene, 5 to 15 parts of polyoxymethylene dimethyl ethers, 15 to 35 parts of petroleum acid, 3 to 9 parts of ethyl formate, 5 to 15 parts of isooctyl nitrate, and 10 to 25 parts of fatty acid glyceri. The methanol diesel fuel is stable in performance, high in resistance to water phase, free of emulsifying and layering, relatively high in cetane number, full of power when in use, low in sulphur content, and meets the environmental protection by exhaust emission.

Description

technical field [0001] The invention relates to an automobile fuel, in particular to a methanol diesel. Background technique [0002] Methanol is a clean fuel, which can effectively reduce the emission of conventional pollutants, especially particulate matter, and reduce smoke and carcinogenicity. The source of methanol is very rich, it can be produced from solid raw material coal, liquid raw material naphtha and residual oil, gas raw material natural gas, oil field gas and coal bed methane. Methanol also has many unfavorable factors as a substitute fuel for diesel. First, because methanol contains hydroxyl groups and is a polar substance, it is difficult to mix methanol and diesel. After mixing, it is easy to separate and has poor stability; second, the ignition point of methanol It is as high as 470°C, which is much higher than the 200-220°C of diesel oil. Therefore, methanol is difficult to compress and ignite, and its ability to spontaneously ignite is relatively poor. ...

Problems solved by technology

Methanol also has many unfavorable factors as a substitute fuel for diesel. First, because methanol contains hydroxyl groups and is a polar substance, it is difficult to mix methanol and diesel. After mixing, it is easy to separate and has poor stability; second, the ignition point of methanol It is as high as 470°C, which is much higher than the 200-220°C of diesel oil. Therefore, methanol is difficult to compress and ignite, and its ability to spontaneously ignite is relatively poor. It will have an adverse effect on the low-speed and low-load operation of the engine; fourth, the viscosity of methanol is low. When the original fuel injection system of the diesel engine is directly used, it will cause system wear and even jamming, which will affect the reliability and durability of the engine. sex

In addition, methanol also has a strong corrosive effect on non-ferrous metals, rubber, etc., the above factors are not conducive to the popularization and application of methanol diesel
