Description
Technical field
The invention belongs to internal combustion engine fuel oil and field of internal combustion engine.
Background technology
1) EU countries promoted the use of oil emulsion in major urban public traffic vehicles to reduce exhaust emission, and in 2004
Oil emulsion technical standard " CEN CWA 15145 " is disclosed, it is specified that in mass ratio, allowing the less kinetic equation loss of sale
The moisture content of (label B) oil emulsion should be in ＞ 5% between ＜ 8%；Allow the more superior discharge of showing of sale
(label A) moisture content should be between 8% to 15%.
2) emulsified fuel technology developed after over one hundred year, and China puts into a large amount of manpower and materials research breasts since the eighties
Change technology.There are many patent document that can be found, these technologies are entirely to study to reach to stablize inexpensive emulsification formula.Have
With that moisture content can be expanded to 30% or more, also simply indicate that these formulas can also reach the transparent shape to maintain a long-term stability
State does not find that it is having more benefits in fuel-economizing and reduction exhaust emission yet.Such as the right of CN101050393A is wanted
It asks and 1) states its water content 12~30%；And " technical data having at present is situated between with being added in the background technology of text document
The amount of water that continues can be up to 30% or so, focus on plus water is without focusing on rate of economizing gasoline, --- --- is it is well known that water is no heat
Because it is not fuel, --- -- toward the excessive water mixing of oil plant do not play not only good effect anti-Er Give applications bring it is certain
Difficulty ".The selection that water content is higher than 30% is actually also clearly negated, and nobody goes to actually attempt to the effect of high-moisture percentage
Fruit.The development of recent engine technology has reached the level that can also make fuel oil close to 100% burning without using oil emulsion.Breast
Change technology has no too big advantage on energy saving, and other than the present invention, this is over more than 30 years through engine rig test Testing and appraisal
The result shows that using the rates of economizing gasoline all super only 10% of all emulsification oil products.And cost is emulsified also close to 10%.Oil emulsion is used
Family cannot get economical and practical.Other than individual local governments are to user's prize funds, all parts of the country fail to be widely applied interior
Combustion engine oil emulsion uses.
3) theoretical efficiency of diesel engine is 61%, and the theoretical efficiency of gasoline engine is 55%.The current middle-size and small-size efficiency of internal combustion engine
Only 25%, frictional force occupies the bigger ratio in theoretical efficiency.Can be opened with emulsified fuel reduces the new way of friction
The middle-size and small-size efficiency of internal combustion engine can be increased to 45~50% by diameter.
4) someone in 1984, which announces water, can become the invention of oil.With 3/4 tap water and 1/4 gasoline and a small amount of medicament match
The puffing gasoline of system, can start automobile, rate of economizing gasoline 44.84%.But in fact water does not become oil, water content is excessive
Water-In-Oil state could not be formed, the aqueous corrosion that dissociates on probation is broken machine, and invention is denied.But its fuel-economizing phenomenon can be sent out with this
Bright theory is explained.
Inventive principle
Before the present invention, all research for oil emulsion is all only at single pair oil emulsion itself, only around stability
The characteristics of being carried out with fuel value two indices, being not bound with internal combustion engine goes to play more potentiality.Use the internal combustion of oil emulsion
Machine, other than the Chemical Physics reaction carried out in combustion chamber.Droplet into cylinder and the oil emulsion of piston clearance,
It explosive can also be evaporated under high temperature.The high-pressure water vapor of generation, which forms steam cushion, reduces friction.When water content is smaller,
Unobvious are acted on, water content reaches a certain level, this effect just highlights.
Quartastroke engine, in intake stroke, fuel injection beginning when piston is downward, when piston is downward, piston lower portion lubricating oil
Pond is easily accessible gap by the oil droplet that bent axle agitation splashes out；Next compression stroke, piston rises, as piston rises, top
Mist of oil is easily pressed into piston clearance, and the oil droplet splashed up from lower part cannot enter gap when piston rises.Further more, piston
Rising compressed gas makes cylinder pressure that can rise to about 30 air pressures.It is also steeply risen in this process temperature, reaches the boiling point emulsification of water
Water in oil.Very fast explosive gasification, make around oil and gas particle be ground into thinner particle, be allowed to burn later more fills
Part.The two features of high temperature, high pressure force mist of oil strongly to penetrate into piston clearance from top to bottom, then arrive at vertex and generate detonation,
Piston does work downwards, and at this moment just the oil emulsion from top strength into piston clearance is since temperature is less than combustion chamber herein, relatively
After combustion chamber is slightly delayed, just when piston is downward, microexplosion can also occur for moisture therein, still, here without abundance
Air, detonation cannot be caused.The steam cushion layer that the water vapour with additonal pressure that droplet microexplosion generates is formed reduces mill
It wipes.And lubricating oil from below heads on the huge buffer brake in top and is difficult to enter gap at this moment, the efficiency of internal combustion engine improves
To about 45~50%.
The principle is also verified on the supercavitating torpedo that modern age occurs.Surface is in the friction of water when torpedo advances at utmost speed
The high temperature of generation has produced one layer of water vapour, this layer of steam cushion makes resistance reduce, its speed of a ship or plane is made to be increased to from more than ten meters per second often
80 meters of second.
Specific implementation mode
Available (rather than kiln is available) the various emulsification oil formulas of existing internal combustion engine can be utilized, water content is adjusted, surveys
Output power of internal combustion engine and fuel consumption are tried, after reaching rate of economizing gasoline nearly 50%.Water content rate of economizing gasoline is increased again to improve not
