Title: Engine pressure regulator

Description:
TECHNICAL FIELD  
       [0001] This invention relates generally to an engine pressure regulator, in particular, an engine pressure regulator used in the engine that can collect hydrogen and oxygen.  
       BACKGROUND OF THE INVENTION  
       [0002] In general, with fuels used in internal combustion engines, external combustion engines, and other combustion apparatus, exhaust gases are generated by combustion to release various types of noxious chemical substances into the atmosphere, thus causing an environmental pollution. These noxious chemical substances include, for example, CO, HC, NOx, and SOx. Heretofore, to suppress generation of such noxious chemical substances, fuel combustion efficiency has been improved by improving the quality of fuels used or by improving various combustion devices. In addition, the exhaust gases released have been treated by a variety of exhaust gas removing devices using catalysts to prevent pollution. However, such prior art methods have been insufficient to reduce pollutive substances, and the improvement of fuel quality has been difficult in view of the costs. To overcome the defects, recently, the industry intends to use fuel activation devices to enhance combustion and reduce harmful gases. In the U.S. Pat. Nos. 4,605,498, 4,711,271, 5,055,189, 5,044,346, 5,080,080, 5,460,144, 5,632,254 and 5,873,353, magnetic field effect or far infrared ray is used to activate fuel to decompose the fuel molecule and therefore enhance combustion and reduce the harmful gases.  
       [0003] Combustion includes fuel, hydrogen in the fuel and oxygen in the air. Activating fuel only improves one element of combustion. Fuels like gasoline are composed mainly of carbon-hydrogen chemical compound with different molecule structures. The main elements of the compounds are carbon and hydrogen. The fuels, which contain high percentage of hydrogen usually, are easily ignited to produce power. Carbon and hydrogen are active elements. They can easily combine with oxygen and then blaze. Therefore if we can provide sufficient air (oxygen is about 20% of air), the combustion of the fuels will be efficient and less harmful gas will be produced. Adding more hydrogen and into combustion equipments like engines can reduce the consumption of fuels and adding oxygen can help the hydrogen both in the fuel and in the air burn and avoid the combine of carbon and hydrogen since usually carbon and hydrogen will combine as harmful gases.  
       [0004] However, in the engine system that can collect hydrogen and oxygen and reused them as described above may face a problem. The problem is that when the oxygen and hydrogen are supplied too much or not sufficient, the pressure inside the engine may become abnormal and cause some problem.  
       SUMMARY OF INVENTION  
       [0005] It is therefore a primary objective of the present invention to provide an engine pressure regulator that can adjust the pressure of an engine efficiently.  
       [0006] The present invention, briefly summarized, in one embodiment discloses an engine pressure regulator, used in an engine that can collect hydrogen and oxygen, the regulator comprises: a body chamber; a connecting tube, through one side of the chamber; a passage mechanism, mounted inside the chamber having a passage connected to the inner space of the chamber; a needle tube mechanism, connected to one end of the connecting tube, and connected to the passage when compressed.  
       [0007] The connecting tube is connected to the tube between the engine and the fuel pressure regulator. When the pressure of the engine is too high, the connecting tube will push the needle tube mechanism and the needle mechanism will connect to the passage and the over pressured gas in the engine will be released to the inner space of the chamber and therefore reduce the pressure. When the pressure of the engine is too low, the inside pressure will cause the gas inside the chamber pass through the needle tube mechanism and the connecting tube to the engine to compensate the pressure.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
     [0012] With reference to FIG. 1, the embodiment is used in an engine system that can collect hydrogen and oxygen. The system has an engine  10  with several cylinders  11  and an cooling device  20  connected to the engine  10 , the cooling device  20  has at least one water tank  21  for outputting cooling water to the engine  10  and inputting heated cooling water from the engine  10 . Part of the heated water is decomposed into oxygen and hydrogen because of high temperature. The separator chamber  50  is for separating liquid and gas, which comprises: an input  52  connected to the engine  10  for receiving heated cooling water; a first output  53 , connected to the water tank  21 , for outputting the heated cooling water to the water tank  21 ; and a second output  54 , connected to the water tank  21 , for outputting the oxygen and hydrogen to the water tank  21 . The oxygen and hydrogen will follow the route of the cooling water (indexed as “a” in FIG. 1) flow into the separator chamber  50 . Since gas is lighter and the flowing speed is faster, so hydrogen and oxygen can flow into the water tank  21  earlier. The temperature inside the water tank  21  is high enough to produce more hydrogen and oxygen.  
     [0013] The storage chamber  60  with sufficient space  61  has an input  62  connected to the water tank  21  for receiving oxygen and hydrogen inside the tank  21  and an output  63  connected to the engine  10  for outputting the oxygen and hydrogen to the cylinders  11 .  
     [0014] However, it is possible that when providing of the oxygen and hydrogen is too much, it will cause the pressure inside the engine too high in an instant. To solve this problem, we can install a pressure regulator  80  connected to the tube between the engine  10  and fuel pressure regulator to release over pressured gas.  
     [0015] In the traditional engine driving system, generally speaking, a fuel pressure regulator is installed to adjust the pressure in the fuel tube. The fuel pressure regulator will have a tube connected to oil tank to collect surplus oil. However the pressure regulator  80  doesn&#39;t have tube connected to oil tank since there will be no surplus oil through the efficient combustion of the present invention.  
     [0016] With reference to FIG. 3, the engine pressure regulator  80  comprises: a body chamber  801 ; a connecting tube  811 , through one side of the chamber  801 ; a passage mechanism, mounted inside the chamber  801  having a passage  813  connected to the inner space of the chamber  801 ; a needle tube mechanism  812 , connected to one end of the connecting tube  811 , and connected to the passage  813  when compressed.  
     [0017] The connecting tube  811  is connected to the tube between the engine and the fuel pressure regulator. When the pressure of the engine  10  is to high, the connecting tube  811  will push the needle tube mechanism  812  and the needle mechanism  812  will connect to the passage  813  and the over pressure gas from the engine will be released to the inner space  81  of the chamber  801  through the needle tube mechanism  812  and connecting tube  811  and therefore reduce the pressure. When the pressure of the engine  10  is too low, the inside pressure will cause the gas inside the chamber  801  pass through the needle tube mechanism  812  and the connecting tube  811  to the engine  10  to compensate the pressure.  
     [0018] Since every engine has different critical pressure to decide when the pressure is too high, the embodiment  80  can further comprises a control valve  814  connected to the needle tube mechanism  812  for controlling the flow of the needle tube mechanism.

The disclosure, however, is illustrated only, and changes may be made in detail, especially, in matters of shape, size and arrangement of parts, materials and the combination thereof within the principle of the invention, to the full extend indicated by the broad general meaning of the terms in which the appended claims are expressed.
