Description

gaseous molecular combustor

technical field

The utility model relates to a gaseous molecular combustion aid.

Background technique

During the normal operation of a general engine, the fuel is exploded and burned in its cylinder for the engine to operate. However, the explosive combustion of air and fuel is often incomplete, thus producing a lot of exhaust gas and engine carbon deposits. When an appropriate amount of water molecules are in the Under high temperature environment, hydrogen and oxygen can be decomposed, so as to obtain the effect of supporting combustion, make the combustion more complete, reduce exhaust emissions, and remove carbon deposits in the engine.

Please refer to Fig. 1, which is a schematic diagram of a known water burner, which includes a bottle body 1 for containing water or a mixed solution of water and ethanol. The bottle body 1 has an air inlet pipe 2, and the air inlet pipe 2 is passed through On the bottle body 1, wherein, the air outlet end of the air inlet pipe 2 is arranged in the liquid contained in the bottle body 1, and an air outlet pipe 3 is further provided on the upper end of the bottle body 1, and the air inlet end of the air outlet pipe 3 is arranged on the bottle body. The body 1 accommodates the liquid above the liquid level, and the gas outlet end of the gas outlet pipe 3 is connected to an intake manifold 300 of an engine 200 . In view of the fact that when the engine 200 is running, the intake manifold 300 will generate a negative pressure, and introduce air for the fuel to mix and explode. Therefore, during the operation of the engine 200, the negative pressure generated by the intake manifold 300 will cause a negative pressure to be generated in the bottle body 1, so that the intake pipe 2 sucks air, and when the air passes through the liquid Bubbles are generated during the process, thereby increasing the amount of dissolved oxygen in the liquid, and the bubbles are broken on the liquid surface to form small oxygen-containing droplets, and the small droplets are released by the negative pressure generated by the intake manifold 300 The attraction is introduced into the engine 200 .

Since the small liquid droplets absorb latent heat and vaporize in the high-temperature environment inside the engine 200 , the ambient temperature during the fuel explosion combustion process can be effectively reduced. However, when the small drop reduces the temperature of the engine, the high water content of the small drop itself causes too much water vapor to be brought into the engine 200, thereby causing knocking of the engine 200 and even affecting the engine. The explosive combustion of its fuel oil, what's more, may cause the engine 200 to be corroded and damaged.

Please refer to Figure 2 again, which is a schematic diagram of another known water burner, which includes a bottle body 4 for containing water or a mixed solution of water and ethanol, and an atomizer 5 is arranged in the bottle body 4 for The liquid contained in the bottle body 4 is atomized to form water molecules, and the upper end of the bottle body 4 is provided with a connecting pipe 6, and the inlet end of the connecting pipe 6 is set at the liquid end of the liquid contained in the bottle body 4. surface, and the air outlet end of the connecting pipe 6 is passed through an atomized water collection bottle 7, the upper end of the atomized water collection bottle 7 is provided with an air outlet pipe 8, and the air outlet pipe 8 is connected to an intake manifold of an engine 200 Tube 300 on.

When the engine 200 is running, the negative pressure generated by the intake manifold 300 will cause a negative pressure to be generated in the atomized water collection bottle 7, and the water molecules generated after atomization by the atomizer 5 will be attracted and introduced. The atomized water is collected in the bottle 7, and then further introduced into the engine 200, and the temperature of the engine 200 is reduced. Although, the water molecules with too high water content can be condensed into water droplets in the atomized water collection bottle 7 when the water content is passed through the atomized water collection bottle 7 by the atomized water collection bottle 7, and make it stagnate in the atomized water collection bottle 7, however, its mechanism of making the water molecules with too high water content condense into water droplets is not good, so its effect is limited, and the water vapor introduced into the engine 200 is still too much, and then the engine 200 does not run smoothly.
