As another example, Figure 11 is the industrial structure diagram of the air intake control valve 10 of pattern shown in Figure 1.
In order to understand the present invention better, prior art and comparison of the present invention in Figure 12 and 13, have been provided.Figure 12 is the schematic representation of intake duct that does not have the internal-combustion engine of Intaker controller, and air stream 110 enters vaporizer 62, and air stream leads on the path of firing chamber with fuel from fuel pipe 66 and mixes mutually therein.
Figure 13 is the schematic representation with internal combustion engine inlet of Intaker controller 10.Under the situation that valve cuts out, air stream enters vaporizer system as shown in Figure 12.When valve member (not drawing among the figure) was opened, air was shunted from engine inlets 111 at 1: 85 place that is in vaporizer 62 upstreams under the atmospheric pressure by the upstream tube 83 of communication passage 38.The air stream 50 that is directed is then by air intake control valve 10, this minute stream 50 flow through Intaker controller 10, become air-flow 51 and flow through downstream tube, it reenters dirty trip passage therefrom.
Can make other variation under the condition of the spirit that does not break away from the present invention, the size that is provided only is the demonstration example of most preferred embodiment of the present invention.For example, can replace the hole of the calibration on the current limiting element with a silk screen or screen cloth, silk screen or screen cloth can be made with metal, plastics or resin film, as long as keep suitable volume ratio.Resin film may be effective especially, as long as the silk screen of resin film also is suitable for pilot pressure and the calibration that needs is provided.And the volume ratio in the hole of first Room and second Room and calibration can be in the proportion of 50-70: 25-35: 0.8-1.2, preferably 55-65: 27.5-32.5: 0.9-1.1.The shape of valve head not only can be Frusto-conical, also can be other shapes, as hemisphere, triangle, pentagon and so on.The quantity of metering hole and shape can change, for example the quantity in hole can several and more than 8 between change, their shape can be circle, ellipse, rectangular, arc and so on.And the valve shifting facilities can be made with any elastic material of the displacement force of calibration that can provide.
In addition, the technician in this technical field can easily change into principle of the present invention and be used for fuel injected engine.
Though do not wish to be restrained to any work theory, the applicant thinks that following forum illustrates in the principle by the abnormal results back that this device reached.
All internal-combustion engines all are by having two or the Otto or the Carnot's cycle work of four stroke cycle, in first cylinder all owing to have a certain proportion of fuel and the vaporization carbide (air-hydrocarbon) existence burn, and best ratio is a hydrocarbons of 14 parts of air ratios, usually this ratio can not accurately be kept, and be uneven according to the actual conditions mixture, sometimes mixture is to be under the correct proportions of air and fuel, but the variation of atmospheric pressure and air temperature may make the air molecule number in the suction port place per unit volume change, and air/hydrocarbon chemical combination is than just having departed from optimum value as a result.
Because the fuel mixture in this variation of air/fuel ratio, cylinder just changes, and is not owing to air excess becomes " oil-poor ", become owing to fuel is excessive exactly " rich oil ", this two states all can make engine efficiency reduce.Like this, air/fuel mixture depends on many factors, and these factors comprise before air temperature, the degree of vacuum in the suction tude, combustion temperature and the burning in the atmospheric pressure, outside air temperature, suction tude and the molecule chemical combination of fuel and air during the burning.
The above embodiments have many significant advantages.Current limiting element of the present invention is handled the effect of air by oxygen molecule has been polarized, and this realizes by one group of calibrated hole by forcing air molecule.Make by current limiting element and by the air that friction has polarized that to reach best molecular mixing between gas and oil and the air molecule before entering the firing chamber easier.But the current limiting element that is used to cause polarization is controlled the effect of number that the air quantity that enters engine air inlet tube plays the molecule of stable chemical combination by the variation of responding engine temperature, intake depression and atmospheric pressure.
As another advantage, regulating air quantity in response to the effect of the valve of the variation in pressure in the suction tude, and then regulating hydrocarbon and the proportional mixing of air.When valve is responded to temperature and pressure in second Room and changed, cause the variation of the air quantity of shunting out from vaporizer by Intaker controller.When the air-flow that flows through vaporizer reduce and not by throttling action cause follow the air inlet vacuum time because the reduction of air velocity in the Venturi tube, the fuel stream that flows through the Venturi tube of vaporizer reduces, the suction of fuel has as a result reduced.
Temperature variation also can cause the variation of pressure.When the temperature variation in the firing chamber, pressure also changes, the mixture of " rich oil " at high temperature can become the mixture of " oil-poor " at low temperatures, these variation of temperature can influence the displacement of valve, and valve is correspondingly revised mixture by allowing more or less polarization air to enter the firing chamber.
As for when the engine retard, in the suction tude of motor, can set up extreme vacuum, and Intaker controller can be opened and makes pressure balance.When motor quickened gradually, it is littler that degree of vacuum becomes at the beginning, and Intaker controller begins to close, and the amount of gasoline that sucks by Venturi tube increases.When the revolution of motor per minute was stabilized in a given speed, degree of vacuum increased and Intaker controller is opened once more.At this moment, the degree of unlatching, for example displacement of valve member can become with pressure difference.Suddenly acceleration can be closed Intaker controller fully, does not have the air shunting.When this state finished, valve member moved with pressure difference with being directly proportional, and this has just guaranteed the optimum degree of the optimal proportion and the molecule chemical combination of air and fuel.According to the working state of the motor that this valve wherein is housed, the amount of the hydrocarbon of use (gasoline or liquid gas) significantly reduces.The test of carrying out with Intaker controller of the present invention shows, compare with motor that need not Intaker controller of the present invention, in the hydrocarbon fuels minimizing scope below of the use that is consumed, maximum conservation of fuel amount is estimated on the height between about 1500.00 meters to be about 58.35% on the sea level with more than the sea level.Along with the increase of height, on a maximum height of thinking the design load of 5750.00 meters (19000.00 feet) more than the sea level, the conservation of fuel amount is reduced to 22.70% such lower limit.Fuel is saved greatly as a result, estimates average saving 40.50%.
Intaker controller also has under all drive conditions and the advantage of saving gasoline in all working scope at motor.And by working with a kind of weak mixture that is controlled, this device helps to make spark plug and firing chamber to keep clean, thereby reduces carbon distribution and pollution.
Certainly, should be appreciated that, can make far-ranging variation and remodeling to above-mentioned most preferred embodiment, therefore point out here, preceding detailed description should be regarded as illustrative rather than restriction the present invention, but also should be understood that it is that following claim comprises that all items that is equal to are limiting scope of the present invention.
