Background technique

Because science and technology industry in recent years is flourishing, though make human enjoyment on the various materials and the convenience in life of obtaining, wherein, closely bound up with people especially with the development of vehicle especially.Yet, because the increase rapidly of vehicle platform number and widely-used fossil fuel (as gasoline etc.), and the various different types of harmful exhaust that disengages in a large number (for example CO, HC, NOx, SOx etc.) makes the air-polluting situation serious day by day.How therefore the abnormality of the global climate result that causes atmospheric ozone layer greenhouse effect that broken hole produces to cause because of atmospheric pollution especially suppress the generation of this type of harmful exhaust in recent years, just becomes the problem that present scientist and relevant dealer institute must eager solutions.

General early stage for suppressing the generation of this type of harmful exhaust, normally handle, yet this kind mode but can only be removed very small amount of harmful matter by the various waste gas removal devices of catalyst that must use, and because of using the waste gas removal device of catalyst, this must use the fuel of particular types, thus can cause the puzzlement when using, moreover the working life of its catalyst is also very limited, so also can cause the trouble that replaces with, so for improving above-mentioned shortcoming, relatively tendency is utilized a kind of fuel activating apparatus of strengthening fuel economy and reducing the harmful exhaust generation in recent years, such as the U.S. the 4th, 605,498,4,711,271,5,055,189,5,044,346,5,080,080,5,460,144,5,632,254, patent cases such as 5,873, No. 353, can utilize magnetic field effect or red line far away to activate fuel, improve the combustion efficiency of fuel so that fuel molecule diminishes, and thereby reduce the discharge amount of harmful exhaust relatively, have the value of certain degree really for present industry.But according to us long-term observation and research, aforementioned patent case or its fuel exciting device of releasing successively mutually, mostly flow in fact in the unreal advertisement of exaggeration, in fact help in fact not quite for the combustion efficiency that promotes fuel, even activation fuel is certain effective method, also only be to make the fuel that does not have perfect combustion originally obtain burning to promote combustion efficiency, so not really do not save fuel, in addition desiring to make fuel perfect combustion also is not only that fuel activating can be solved, whether wherein more involve the oxygen of being supplied enough, whether the hydrogen composition in the fuel is enough ... etc. problem, unless can in the process of firing unit running, obtain the energy of regeneration to supply with this firing unit, otherwise, can not be at last really can fuel saving and reduce waste gas and produce.Based on this, be necessary in fact to go to another way to think deeply fuel saving how and solve the problem of exhaust combustion gases.

According to our research, mainly formed such as fuel such as gasoline by the hydrocarbon of various different molecular structures, Main Ingredients and Appearance is carbon and protium, and its boiling point of hydrogen content the higher person is low and volatility is good in the structure, is easy to light ignite and produce power.In addition, carbon and protium all are the active elements of chemical property, can be very fast with oxygen element in conjunction with and produce combustion phenomena, therefore, as long as enough air (air contains 1/5th oxygen approximately) are provided, fuel must burn easily, that is to say, as long as oxygen is supplied enough, fuel promptly might more fully burn and not have the waste gas generation.Therefore, the direction of our thinking promptly is how to supply more hydrogen and oxygen to such as firing unit inside such as engines, also be, as long as the more hydrogen of supply, can make the relative reduction of expending of gasoline, or say that can add more hydrogen strengthens power output to improve explosion energy, in addition, also just can make from the hydrogen of fuel itself and the extra hydrogen that adds and be easier to light and burn fully as long as supply polyoxy more, otherwise unnecessary hydrogen and carbon are easy to be combined into harmful gas.

Yet, when reaching when betiding the hydrogen of car engine inside and oxygen and take out for the purpose utilized again, as long as be supplied to the hydrogen of engine and oxygen when too much, higher situation promptly may take place because of quick-fried the increasing of energy to press in the engine, this will make the running of engine have some setbacks, even may cause the quick-fried situation of dashing of vehicle.Therefore, how can utilize hydrogen and the oxygen person who is reclaimed safely, real is the task of top priority.

Summary of the invention

Main purpose of the present utility model is to provide a kind of pressure regulator with on the engine of being located at recyclable hydrogen and oxygen, therefore solves and presses higher or not enough problem of moment in the engine.

The utility model to achieve these goals, a kind of engine pressure regulator is provided, it is characterized in that, be located in the engine of recyclable hydrogen and oxygen, establish a pin mouth on this pressure regulator, and there is a space its inside, is provided with a pinhole device and passes this pressure regulator and be connected to this engine in this space.

Engine pressure regulator of the present utility model, also can be external on the pipeline between this engine and the existing fuel pressure regulator, and this pinhole device inside is established a pin hole and is passed to this connecting tube and establish a bigger runner at least and be communicated with this pin hole and this space establishing a connecting tube on this pinhole device.

Embodiment

See also shown in Figure 1, for the utility model preferred embodiment is used in a kind of situation of utilizing engine to produce the mechanism of hydrogen and oxygen, this utilizes engine to produce the mechanism of hydrogen and oxygen mainly for applying to an engine driving system, this engine driving system comprise at least an engine 10 with some cylinders 11 with outputting power, and a cooling unit 20 that is arranged in this engine 10 keeping this engine 10 in suitable temperature, and this cooling unit 20 and at least tool one water tank 21 with the output low-temperature cooling water to this engine 10, and the input high-temperature cooling water of discharging by this engine 10.This mechanism also comprises at least:

One gas-liquid separator 50, its inside has suitable space 51, and have at least an input end 52 to be connected to this engine 10 and discharge high-temperature cooling water part A, for this high-temperature cooling water flow through this space 51, one first output terminal 53 be connected to this water tank 21 with export this high-temperature cooling water to this water tank 21 and one second output terminal 54 be connected to this water tank 21 with output hydrogen and oxygen to this water tank 21.That is to say, water will have part to be broken down into hydrogen and oxygen when high temperature, these hydrogen and oxygen will flow in this gas-liquid separator 50 along with the circulation loop a of cooling water, because it is very fast that gas gentlier reaches flow velocity, so hydrogen and oxygen can be inputed in this water tank 21 by this second output terminal 54 earlier, and the water temperature of these water tank 21 inside still can continue to break water into hydrogen and oxygen, therefore has the utilization that more hydrogen and oxygen take place for output at water tank 21;

One storeroom 60, its inside has suitable space 61, and having first input end 62 at least is connected to this water tank 21 and is connected to this engine 10 so that this hydrogen and oxygen are introduced the cylinder 11 of these engine 10 inside, in order to promote the combustion efficiency of this engine with the hydrogen of importing these water tank 21 inside and oxygen, an output terminal 63.

Because the extra adding of hydrogen, can effectively increase the explosion energy of engine internal and can export higher power to drive relevant mechanical component, for automobile, can be described as engine horsepower and effectively promoted.Again because the extra adding of oxygen, make that the burning of fuel oil will be more fast and more complete, for automobile, be can effectively promote combustion efficiency and significantly reduce discharge amount of exhaust gas, for environmental protection quite positive help is arranged.In addition, do not considering to promote under the situation of engine outputting power,,, can be described as and significantly save expending of fuel oil automobile because the extra adding of hydrogen and oxygen makes gasoline can reduce relatively the supply of engine.In general, utilize above-mentioned mechanism can be easily by obtaining a regeneration energy hydrogen and an oxygen in the conventional engine drive system, expend to substitute fuel oil partly, and promote combustion efficiency of fuel oil, obtain fuel-efficient, environmental protection, and many Practical Benefit such as big shaft horsepower according to this.

Yet, since hydrogen and oxygen additionally infeed engine, may (provide extra combustible element because of quick-fried the increasing of energy sometimes because of hydrogen, oxygen then provides extra combustion-supporting element), may cause and press moment higher in the engine, in order to solve this contingent problem, it is the corresponding the utility model that proposes, also be, see also Fig. 1 and Fig. 2, pressure regulator 80 of the present utility model is the pipelines that are arranged between this engine 10 and its fuel pressure regulator (having now), in order to being released into the pressurized gas of this engine internal, and reach the purpose that discharges engine internal pressure.Though, in existing engine driving system, generally all be provided with fuel pressure regulator, and keep level pressure for the pressure in the fuel metering pipeline.But this fuel pressure regulator is equipped with pipeline again to fuel tank except pressure regulation, sprays too much fuel oil to fuel tank to reclaim.The alleged pressure regulator 80 of this patent then need not to connect establishes pipeline to fuel tank, this be because this patent such as above-mentioned as can significantly promote combustion efficiency, so that fuel oil almost completely burns totally, also just do not have superfluous fuel oil need be back to fuel tank, also promptly this pressure regulator 80 only needs to design and comparatively simple at release of pressure.

See also Fig. 3 again, establish a pin mouth 801 on this pressure regulator 80, and its inside has a space 802, is provided with a pinhole device 81 and is connected to pass this pressure regulator 80 on the pipeline between this engine 10 and the existing fuel pressure regulator in this space 802.Wherein, establish a connecting tube 811 on this pinhole device 81 and be external to this engine 10 and commonly use on the pipeline between the fuel pressure regulator, and a pin hole 812 is established to pass to this connecting tube 811 and to establish a bigger runner 813 at least to be communicated with this pin hole 812 and this space 802 in these pinhole device 81 inside.So, utilize the restriction of the pin hole 812 of this pinhole device 81, these engine 10 pressure inside need big to a certain degree the beginning can make its internal high pressure gas crowded this runner 813 of flowing through through this pin hole 812 of moment so that this space 802.Similarly, the pressure in this space 802 also need be put aside to a certain degree, could squeeze through this pin mouth 801 and release to the outside.By this mode so that this engine 10 can obtain release of pressure effect timely when interior pressure is higher, and at this engine 10 when interior pressure is not enough, the pressure in this space 802 can cover in this engine 10.In addition, because the engine of different performance, the critical value of its internal pressure is all inequality, therefore, above-mentioned pin hole 812 places still can establish a control valve 814 to control the flow size of this pin hole 812, by this mode, promptly utilize flow that this control valve 814 decides this pin hole 812 in (only show among Fig. 3 that a sketch represent the relation of this control valve and this pin hole) according to this critical value, in fact this control valve also can be other form.

In the explanation by above-mentioned preferred embodiment, be easy to know that the utility model really can be for applying to above-mentioned the utilization in the mechanism that engine produces hydrogen and oxygen, to reach fuel saving, promote power output and to meet benefit such as environmental protection notion.Simultaneously, more can thereby make this engine be unlikely the situation person that high pressure is unusual or low pressure is not enough is taken place.
