Furthermore, the terms: first, second, etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features shown. In describing the present invention, unless otherwise expressly specified or limited, the terms: mounting, connecting, etc. should be understood broadly, and those skilled in the art will understand the specific meaning of the terms in this application as they pertain to the particular situation.
Referring to fig. 1, which is a schematic structural diagram of an intake pipe of an engine in the prior art, it can be seen from the figure that an intake pipe 3 is connected to an engine 2 for supplying air to the engine 2, a fuel injector 1 is arranged on the intake pipe 3 at a position close to the engine 3, and the air flue injection fuel supply system has the following disadvantages in the case of meeting the existing development requirements: under the working conditions of small load and partial load, because the movement intensity of pipeline airflow is weak, the phenomena of uneven oil-gas mixing, incomplete fuel evaporation under partial working conditions and oil film formation on the wall surface of the air inlet pipeline exist. The defects greatly reduce the efficiency of the gasoline engine and increase the fuel consumption of fuel.
Referring to fig. 2 to 7, in the engine intake manifold with an embedded air intake pre-swirl structure of the present application, the intake manifold 3 is connected to the engine 2 and is used for supplying air to the engine 2, a fuel injector 1 is disposed at a position on the intake manifold 3 close to the engine 3, the fuel injector 1 is used for injecting fuel into the intake manifold 3, an air intake pre-swirl element 4 clamped in an inner cavity of the intake manifold 3 in an embedded assembly manner is disposed in a position outside the fuel injector 1 on the intake manifold 3, the air intake pre-swirl element 4 includes an annular main body 41, and a plurality of cyclone guide pieces 42 uniformly distributed are disposed on an outer wall of the annular main body 41.
Specifically, the annular body 41 is clamped in the inner cavity of the air inlet pipeline 3 through the cyclone guide sheet 42 on the outer wall thereof, so that the structure is simple, the assembly is convenient, and no other installation structure is required. The prerotation angle a of the cyclone guide sheet 42 is 10-20 degrees, preferably about 15 degrees, if the angle is too large, the gas flow area between the blades is reduced, and the throttling effect on the pipeline is realized. If the angle is too small, the change of the motion state of the air flow is too weak, and the effect of improving the oil-gas mixture by the rotation of the air flow cannot be achieved.
In addition, the distance b between the air inlet pre-rotation piece 4 and the engine 2 is 1~2 times of the pipe diameter of the air inlet pipeline, if the distance is too far, the airflow rotation effect is weakened, the oil beam is further broken, the thinning effect is weakened, and the effect of reducing the formation of an oil film on the wall surface of the pipeline is also weakened synchronously. If the distance is too close, the air flow has certain interference effect on the atomizing process of the nozzle oil beam and is not beneficial to the atomizing process of the nozzle oil beam.
As can be seen from the figures, in the present application, the annular body 41 is fitted coaxially with the air intake duct 3, without affecting the passage of the primary air flow at the location of the central axis. And the inner diameter c of the annular main body 41 is 70% -85% of the inner diameter of the air inlet pipeline 3, the structure enables most of the air flow in the central part to pass through the annular main body 41 without influencing the passing of the large air flow, and a small part of the air flow in the periphery passes through the cyclone guide sheet 42 and is guided to form a cyclone flow, the cyclone flow can influence the air flow in the central part, so that the cyclone flow starts to be formed from the periphery to the center as a whole, and meanwhile, the peripheral cyclone flow can rub the pipe wall of the air inlet pipeline 3, and the formation of an oil film on the wall surface of the pipeline is favorably reduced.
Based on the above structure, the intake air prerotation member 4 in the present application has two different embodiments.
Fig. 3 to 5 show the air inlet pre-rotation element 4 in the first embodiment, as can be seen from the figures, the air inlet pre-rotation element 4 has a cylindrical ring-shaped main body 41, 6 cyclone guide pieces 42 are uniformly arranged on the outer wall of the ring-shaped main body 41, the inner wall of the ring-shaped main body 41 is smooth and has no other structure, the air inlet pre-rotation element 4 can be integrally and embedded and clamped to the corresponding position on the air inlet pipe 3 through the cyclone guide pieces 42, and the purposes of smooth passing of the middle air flow and guiding and rotating of the peripheral air flow are achieved.
Fig. 6 to 7 show the air inlet pre-rotation member 4 in the second embodiment, as can be seen from the figures, the air inlet pre-rotation member 4 has a cylindrical ring main body 41, 6 cyclone guide plates 42 are uniformly arranged on the outer wall of the ring main body 41, and at the same time, 6 inner guide plates 43 which are consistent with the pre-rotation direction of the cyclone guide plates 42 and are symmetrical in one-to-one correspondence are uniformly arranged on the inner wall of the ring main body 41, which can increase the guide area, increase the initial rotation guide airflow, make the rotation of the cyclone flow more powerful, and do not affect the passing of the intermediate airflow.
In the above embodiment, the number of the guide pieces can be set as required, for example, 5 to 8 guide pieces can be set according to different sizes of the pipe diameters of the air inlet pipes.
In the technical scheme in this application, the periphery in admission line 3 is established to the blade of prewhirl structure, and the centre is the through-hole formula, and the difference of this kind of structure and the direct turbine blade structure that sets up lies in: the structure of the turbine structure is directly arranged, so that the structure of the arranged assembly body is more complicated, and if foreign matters enter the pipeline, potential failure phenomena such as impact, clamping stagnation and the like to the turbine blades occur; the turbine blade structure component has a flow limit value due to the structure of the turbine blade structure component, and has a limit on the flow rate, so that scheme matching is required under the high-rotating-speed working condition and the large air inflow of the engine, and the applicability of the same turbine blade structure is low; in addition, the moving rotating part in the pipeline needs to be inspected, maintained and maintained regularly at a later stage, and if the turbine blade fails, for example, the phenomenon of corner missing exists, air inlet abnormal noise is easy to generate under the rotating motion, the cost is high, and the effect is poor.
And the embedded prerotation structure adopted in the application is as follows: adopt the fixed blade structure, body simple structure does not have the rotating motion piece, and later stage non-maintaining, maintenance, and can equally realize admitting air in the function and revolve the effect in advance. In addition, in the application, the middle of the engine is provided with the through hole type structure, the phenomenon of pipeline airflow blockage caused by overlarge air inflow under the working condition of high rotating speed of the engine can be prevented, meanwhile, the air inlet pipeline body is changed a little, the popularization and application range of the subsequent market is wide, and the engine can be used for pre-installing the automobile host factory, refitting the after-sale market and the like.
In this application, the piece 4 is revolved in advance to the air admission arranges in the left side of sprayer 1 (keep away from the engine), carries out the adjustment of prewhirling to the gas motion state in advance, has further broken, the effect of refining to the oil beam simultaneously at sprayer 1 oil spout atomizing in-process, all has fine effect in the effect that oil gas mixing motion path length, oil gas mixing effect, reduction pipe wall oil film formed.
The engine intake duct system according to the present application can be used for a small engine such as a motorcycle in which a supercharger cannot be separately provided.
As can be seen from the above description, in the present application, an embedded inlet pre-swirl element 4 is added to the inlet pipe 3 at a position away from the front end of the fuel injector 1, and the flow guiding effect of the cyclone guiding plate 42 on the inlet pipe 3 converts the moving direction of the part of the air flow flowing through the cyclone guiding plate 42 in the inlet pipe 3 from parallel pipeline axes to organized rotation around the pipeline axes. The oil beam can be further crushed and refined in the process of impacting the oil beam by the rotating airflow, and the movement path of oil-gas mixing is prolonged under the same air inlet pipeline condition, so that the effect of further improving the oil-gas mixing is achieved. The rotating airflow has friction and heat generation effects on the pipe wall, which is beneficial to reducing the formation of an oil film on the wall surface of the pipeline and further promoting the evaporation of the oil film under heating, thereby achieving the effect of reducing fuel consumption and further improving the efficiency of the gasoline engine.
The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that can be easily made by those skilled in the art are all within the scope of the present invention.
