Problems solved by technology

[0010] Another example is ethanol automobile: because the ethanol used must be more than 99.7% absolute ethanol, and the manufacturing cost of absolute ethanol is much higher than that of gasoline, and the amount of blended combustion is only 10% (Brazil can reach 25%); Burning anhydrous ethanol, its replacement ratio to gasoline is 1.6:1, the cost is higher, and it is not suitable for China's national conditions at all

Embodiment 1

[0028] A kind of alcohol hydrogen fuel for engine, it is characterized in that, in gasoline engine, methanol is used as fuel, and the percentage that keeps the volume of hydrogen in the engine accounts for gasoline engine air intake is 1.0%, and the rest is air, wherein hydrogen comes from part of methanol steam cracking.

[0029] When the engine speed is 1200r / min, the temperature and pressure changes of the alcohol-hydrogen fuel combustion in the engine are detected. The temperature range of the mixed combustion of hydrogen and atomized methanol in the engine is 600-950°C; The pressure range of mixed combustion in the engine is 0.5-4.8×10 6 Pa.

Embodiment 2

[0031] A hydrogen alcohol fuel for an engine is characterized in that methanol is used as fuel in a gasoline engine, and the volume of hydrogen in the engine accounts for 2.0% of the intake air volume of the gasoline engine, and the rest is air, wherein the hydrogen comes from part of the methanol steam cracking.

[0032] When the engine speed is 1200r / min, the temperature and pressure changes of the alcohol-hydrogen fuel combustion in the engine are detected. Among them, the temperature range of the mixed combustion of hydrogen and atomized methanol in the engine is 600-1020 ° C; The pressure range of mixed combustion in the engine is 0.5-5.5×10 6 Pa.

Embodiment 3

[0034] A hydrogen alcohol fuel for an engine is characterized in that methanol is used as fuel in a gasoline engine, and the volume of hydrogen in the engine accounts for 2.8% of the intake air volume of the gasoline engine, and the rest is air, wherein the hydrogen comes from part of the methanol steam cracking.

[0035] When the engine speed is 1200r / min, the temperature and pressure changes of the alcohol hydrogen fuel combustion in the engine are detected. The temperature range of the mixed combustion of hydrogen and atomized methanol in the engine is 600-1080 ° C; The pressure range of mixed combustion in the engine is 0.5-5.8×10 6 Pa.

Abstract

The invention discloses alcohol hydrogen fuel for an engine. The alcohol hydrogen fuel is characterized in that methanol is used as fuel in a gasoline engine, volume of hydrogen in the gasoline engine is ensured to account for 1.0-4.5% of air inflow of the gasoline engine, and the hydrogen comes from splitting decomposition of part of methanol steam. Expansion efficiency during burning of the alcohol hydrogen fuel is higher than that of gasoline burning, so that the engine can reach larger output torque and higher power, and the problem that the alcohol hydrogen effectively replaces gasoline is solved fundamentally. The alcohol hydrogen fuel has the advantages that methanol can be acquired everywhere, so that the alcohol hydrogen fuel is low in using cost; the alcohol hydrogen fuel is pollution-free and good in burning effect during burning; the alcohol hydrogen fuel belongs to renewable energy resources, thereby being capable of replacing nonrenewable energy resources for use.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to a hydrogen alcohol fuel for engines. Background technique [0002] According to the self-data of "BP Statistical Yearbook of World Energy", as of the end of 2011, the global oil reserves were about 1.653 trillion barrels. According to the current global consumption rate of 80 million barrels per day, which is very conservative, the current world oil reserves can be For global consumption for 54 years. [0003] As a limited resource, oil will become more and more tense in the face of the development of world industrialization and the mass use of automobiles; the price of oil has risen from US$10.58 at the end of the last century to US$100 today, and the rising speed is the highest in the history of oil. It is rare, and it is even rarer in the growth rate of other bulk resource products. The soaring price of oil has forced countries all over the world to do everything possible to f...
