The model utility content
The purpose of this utility model is to provide a kind of vortex air intake structure of motor car engine, solve the burning of current engine interior and be subject to the restriction of engine structure, there is the problem at air-flow dead angle, reach and overcome the inadequate purpose of air-flow dead angle, fuel gas buring and discharge, improve the efficiency of fuel oil.
The purpose of this utility model is achieved through the following technical solutions:
The vortex air intake structure of motor car engine, comprise cylinders with small diameter, large-diameter cylinder body, cylinders with small diameter is connected by arc section with large-diameter cylinder body, also comprise the little beam barrel be sleeved in cylinders with small diameter, large-diameter cylinder body, the axis of little beam barrel, cylinders with small diameter, large-diameter cylinder body and arc section is all on same straight line, in the little beam barrel outside, a plurality of guide plates are installed, guide plate, little beam barrel, cylinders with small diameter, large-diameter cylinder body form a plurality of helical ducts.The utility model forms the external casing of shell as gas flow by the 3 stops cylindrical shell, that is: coaxial cylinders with small diameter, large-diameter cylinder body, arc section, arc section is as the link between cylinders with small diameter and large-diameter cylinder body, be set with in the enclosure a little beam barrel, between little beam barrel and shell, form passage, little beam barrel inside also forms passage, mounting guiding board in the passage of little beam barrel outside, form a plurality of helical ducts, during use, the large-diameter cylinder body end is connected with the waste pipe road, the cylinders with small diameter end is connected with motor, induction part is divided into two parts: a part enters motor from the passage of little beam barrel inside, another part enters into motor through the helical duct of too small beam barrel outside, in this two-part gas, because little beam barrel internal diameter is constant, the gas velocity self-consistentency that it is flowed through, keep state of equilibrium, and the gas of the helical duct of flowing through, owing to from large-diameter cylinder body, entering cylinders with small diameter, dwindling of its area of flowing through, must cause the flow velocity of gas to be accelerated, outlet port at cylinders with small diameter forms two kinds of mobile gases: from stablizing directly to air-flow that little beam barrel enters, the fast gas entered from helical duct, it flows to as straight outside tangent line to air-flow, two kinds of different in flow rate, the air-flow acting in conjunction of direction forms eddy current, gas can produce two effects at the eddy current of engine interior: with the air entered, mix more abundant vaporific gasoline, also can all take away by the waste gas after burning after burning simultaneously, avoid the problem at air-flow dead angle, reach the purpose of the rear gas of abundant discharge combustion, improved the efficiency of fuel oil.
Described guide plate is evenly distributed on the little beam barrel outside.Further, in order to form more stable eddy current, guide plate is evenly distributed on the little beam barrel outside, guide plate is arranged according to the mode of spiral of Archimedes in the little beam barrel outside, form the Archimedian screw passage, situation is preferably, and the distortion of guide plate is less than one-period, be that the approach axis of helical duct and the angle that flows out the direction process are less than 360 °, avoid the long runner barrier effect to air-flow.
Described arc section and cylinders with small diameter connect into level and smooth curved surface, and arc section and large-diameter cylinder body connect into level and smooth curved surface.Further, as further optimization of the present utility model, between arc section and cylinders with small diameter, arc section and large-diameter cylinder body, all connect into level and smooth curved surface, the Dead Core Problems of avoiding self angle to cause.
Described guide plate is five.Preferably, five guide plates can form five helical ducts, if guide plate increases, can cause flow area to reduce, and air quantity reduces, and guide plate reduces, and can not form again eddy current preferably, and preferred mode is five.
The utility model compared with prior art, has following advantage and beneficial effect:
The vortex air intake structure of 1 the utility model motor car engine, be set with in the enclosure a little beam barrel, between little beam barrel and shell, form passage, little beam barrel inside also forms passage, mounting guiding board in the passage of little beam barrel outside, form a plurality of helical ducts, during use, the large-diameter cylinder body end is connected with the waste pipe road, the cylinders with small diameter end is connected with motor, induction part is divided into two parts: a part enters motor from the passage of little beam barrel inside, another part enters into motor through the helical duct of too small beam barrel outside, in this two-part gas, because little beam barrel internal diameter is constant, the gas velocity self-consistentency that it is flowed through, keep state of equilibrium, and the gas of the helical duct of flowing through, owing to from large-diameter cylinder body, entering cylinders with small diameter, dwindling of its area of flowing through, must cause the flow velocity of gas to be accelerated, outlet port at cylinders with small diameter forms two kinds of mobile gases: from stablizing directly to air-flow that little beam barrel enters, the fast gas entered from helical duct, it flows to as straight outside tangent line to air-flow, two kinds of different in flow rate, the air-flow acting in conjunction of direction forms eddy current, gas can produce two effects at the eddy current of engine interior: with the air entered, mix more abundant vaporific gasoline, also can all take away by the waste gas after burning after burning simultaneously, avoid the problem at air-flow dead angle, reach the purpose of the rear gas of abundant discharge combustion, improved the efficiency of fuel oil,
The vortex air intake structure of 2 the utility model motor car engines, guide plate is arranged according to the mode of spiral of Archimedes in the little beam barrel outside, form the Archimedian screw passage, situation is preferably, the distortion of guide plate is less than one-period, be that the approach axis of helical duct and the angle that flows out the direction process are less than 360 °, avoid the long runner barrier effect to air-flow;
The vortex air intake structure of 3 the utility model motor car engines, simple in structure, less for the improvement of available engine, be easy to promote the use of.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but mode of execution of the present utility model is not limited to this.
Embodiment
