Description
Technical field
The invention belongs to the preparations of internal combustion engine alternative fuel, and in particular to a kind of nanometer hydrogen that can be used as diesel fuel
The intermittent preparation method of bubble/diesel blended fuel.
Background technique
It for many years, is that economic development and people's lives improvement are made in dynamic field using vapour, diesel oil as the internal combustion engine of fuel
Brilliant contribution, but since the new century, with government and street levels constantly mentioning to energy crisis and environmental pollution degree of concern
The crisis in moral convictions of height, conventional liquid fuel internal combustion engine is increasingly sharpened.Wherein, conventional liquid fuel internal combustion engine is in pollutant emission side
The disadvantage in face is especially prominent, researches and develops the key point that effective pollution reduction technical measures have become internal combustion engine final and decisive juncture.
Hydrogen (H2) it is a kind of generally acknowledged efficient, clean energy resource, it is also very long in the research history of field of internal combustion engine,
Research finds that combustion in IC engine pure hydrogen and hydrogen and conventional liquid fuel blending burning can be improved the diesel engine thermal efficiency, reduces
Pollutant emission.Currently, the most common hydrogen-containing fuel combustion system includes: pure hydrogen burning, hydrogen/traditional liquid combustion both at home and abroad
Expect double fuel burning, hydrogen/conventional liquid fuel blending burning, wherein hydrogen/conventional liquid fuel blending burning further include:
Hydrogen/conventional liquid fuel double ejecting system intake port injection, hydrogen/conventional liquid fuel double ejecting system cylinder injection, hydrogen
The working methods such as gas intake port injection/conventional liquid fuel cylinder injection.But above several working methods require 2 sets of fuel sprays
System is penetrated, it is high that this not only results in hardware cost, injection system difficult arrangement, and to guarantee the hydrogen sprayed respectively and biography
System liquid fuel can reach optimal fiting effect, the air inlet optimization of double ejecting system internal combustion engine and burning tissues, or even
It is all more much more complex than single-injection system internal combustion engine with demarcating.
It is inconvenient to internal combustion engine design and use bring to reduce double ejecting system, hydrogen and conventional liquid fuel are configured
Being sprayed at uniform fuel combination by a spraying system be most convenient and fast solution.But under room temperature, normal pressure, hydrogen exists
Solubility in diesel oil is lower, it is difficult to meet fuel combination ratio required for improving in-cylinder combustion and therefore prepare high Blend proportion
Hydrogen/diesel blended fuel of example must select special mixing, preparation principle and technique.Microvesicle hybrid technology is eighties of last century
The novel non-homogeneous mixture technology of preparing that end has gradually developed, by the way that gas componant to be separated into nanometer, Asia in a liquid
The micro-bubble of micron level realizes the preparation of metastable state gas/liquid homogeneous mixture, which has mature application model at present
Example, such as be widely applied in oil exploitation, medical imaging field.But the continuous phase of existing microvesicle mixture technology of preparing
It is all water, dispersed phase is the hydrophobic gas such as air, hydrogen, general to improve micro bubbles by the way that surfactant is added in water
Stability, therefore, such technology preparation microbubble actually belong to emulsification microvesicle rather than real gas microbubbles.But by
Hydrophilic polar structure is all free of in diesel oil and hydrogen, the surfactant based on the amphipathic structure of hydrophilic/lipophilic is to hydrogen and bavin
The promote meaning of oily microvesicle mixed process is little, and most surfactants have unfavorable shadow to the in-cylinder combustion of diesel engine
It rings, therefore, the preparation of hydrogen/diesel oil microvesicle fuel combination needs to develop completely new bubble formation method.
Domestic and international result of study shows that the pressure for increasing hydrogen can significantly improve hydrogen with the temperature for improving diesel oil and exist
Solubility in diesel oil, such as at 50 DEG C, solubility of the hydrogen in diesel oil is 0.0114 (molar fraction) under normal pressure, by hydrogen
After pressure is increased to 2MPa, solubility of the hydrogen in diesel oil is just promoted to 0.0382 (molar fraction)；And it is increased in temperature
At 150 DEG C, under 2MPa pressure, solubility of the hydrogen in diesel oil is further promoted to 0.0405 (molar fraction).On the other hand,
After continuous phase temperature and Hydrogen Vapor Pressure reduce, the hydrogen dissolved in diesel oil will be in hypersaturated state and be further converted into
The temperature and pressure of bubble, continuous phase is more uniform, and the hydrogen that supersaturation is precipitated is formed by smaller (the most gas of bubble diameter
Bulb diameter is in Nano grade, as shown in Figure 2), meanwhile, number of bubbles is more.
