Because present embodiment has the similar structure of above-mentioned the 3rd embodiment, therefore the difference between these two embodiments only is described.
On the internal surface of flow-disturbing body 430, form the ribs 434 of inwardly radially extending.The same with above-mentioned first embodiment's ribs, each ribs 434 all has the little surface vertical with the flow direction of fuel oil and AIR MIXTURES, so that ribs does not hinder flowing of hollow mixture by the flow-disturbing body.Hub 435 is fixed in the end of ribs 434, in hub 435, forms through hole, make its direction identical, and will back shaft 436 insert in the through holes and and support by through hole with the hollow direction of flow-disturbing body.With the auxiliary flow-disturbing body 437 that is formed with a plurality of blades on the outer surface be fixed in back shaft 436 around.In this case, in order to form eddy current or turbulent flow, preferably, make auxiliary flow-disturbing body 437 around the direction rotation opposite with the flow-disturbing body.As long as auxiliary flow-disturbing body 437 can be with respect to hub 435 rotations.Therefore, back shaft 436 can be subjected to the rotary support of hub 435, perhaps can support auxiliary flow-disturbing body 437, makes it around back shaft 436 rotations.
But for the ease of assembling, the previous case is preferable.Preferably, comprise that the external diameter of auxiliary flow-disturbing body 437 of blade is less than the internal diameter of the flow-disturbing body 430 that comprises blade.In this case, since the same with above-mentioned second embodiment, can therefore can produce stronger mixture eddy current or turbulent flow with assisting flow-disturbing body 437 parts or being arranged at fully in the inner space that limits by flow-disturbing body 430.And each blade of auxiliary flow-disturbing body 437 and flow-disturbing body 430 all has spiral-shaped.More preferably, the blade of auxiliary flow-disturbing body and flow-disturbing body has the opposite spiral of direction, so that auxiliary flow-disturbing body and flow-disturbing body can rotate around opposite direction.
Figure 11 is the perspective exploded view of the fuel mixing means of internal-combustion engine according to a fifth embodiment of the invention, Figure 12 is the perspective view that shows the assembled state of fuel mixing means shown in Figure 11, and Figure 13 is the sectional view that the fuel mixing means of Figure 11 is installed on the state at intake duct place.The internal-combustion engine of present embodiment comprises support ring 510, and it inserts in the inlet of intake duct regularly, and intake duct is formed in the cylinder head and as passage fuel oil and AIR MIXTURES are fed to the firing chamber.Support ring 510 adopts the shape of hollow cylinder usually.But according to the entrance shape that will insert the intake duct of support ring regularly, support ring can have elliptical shape or polygonal shape.And, in order to guarantee the Peak Flow Rate by hollow fuel oil of support ring and AIR MIXTURES and obtain required intensity that preferably, when observing in the sectional view at Figure 13, the internal surface of support ring 510 adopts the meniscus shape of inside radial protrusion.
Ribs 520 is inwardly radially extended from the internal surface of support ring 510.Preferably, ribs 520 adopts the wing shape that has certain width on the back shaft direction of support ring, so that along specific direction guiding fuel oil and Air mixing logistics, and can not hindered.Ribs can have a certain degree with the flow direction of mixture.In order to support back shaft as described below 530, can provide ribs 520 as much as possible as required.
The end of back shaft 530 is fixed on the ribs 520.Back shaft 530 comprises along the extension 531 that the back shaft direction of support ring 510 is extended and the curved section 532 crooked and that extend from the extension in the extension part office.Determine the length of extension 531 according to the curved shape of intake duct.But preferably, the length of extension makes at least a portion of extension extended outside support ring 510.
And preferably, the diameter of curved section 532 is less than the diameter of extension 531.Because back shaft 530 is crooked, therefore the flow-disturbing body that is arranged at back shaft one end can be positioned over the depths in the intake duct, and the curved shape of tube inlet is not how.
One end of the curved section 532 of back shaft 530 is inserted in the flow-disturbing body 540.For this reason, flow-disturbing body 540 adopts the state of hollow cylinders, and is formed with a plurality of blades on its outer surface, and back shaft 530 is inserted in flow-disturbing bodies 540 hollow.In order to promote the generation of eddy current or turbulent flow, preferably, except flow-disturbing body 540, can further provide auxiliary flow-disturbing body 550.
