Summary of the invention

The technical problems to be solved in the utility model provides a kind of suction tude structure-improved that promotes horsepower and low speed fuel saving effect at a high speed that has.

For solving the problems of the technologies described above, the utility model proposes a kind of suction tude structure-improved, wherein, it establishes the mouth of pipe that extends out in a hollow tube two ends symmetrical ring, wherein the inwall of this hollow tube is equipped with a plurality of protruding walls that is unidirectional radial arrangement mutually, in between protruding wall, respectively form the helical conduit, and this protruding wall and conduit two ends then respectively have retaining wall, form oblique cambered surface between the ora terminalis of this retaining wall and the mouth of pipe.

Aforesaid suction tude structure-improved, the described mouth of pipe connects suction port and engine respectively.

Aforesaid suction tude structure-improved, the protruding wall between described conduit is equidistantly alternately.

The utility model has also proposed a kind of suction tude structure-improved, wherein, it establishes first mouth of pipe and second mouth of pipe that extends out in a hollow tube two ends symmetrical ring, wherein the inwall of this hollow tube has a plurality of protruding walls that is unidirectional radial arrangement mutually, in between protruding wall, respectively form the helical conduit, and this protruding wall and conduit two ends then respectively have first retaining wall and second retaining wall, and this first retaining wall and second retaining wall form oblique cambered surface respectively and between the ora terminalis of first mouth of pipe and second mouth of pipe.

Aforesaid suction tude structure-improved, this first mouth of pipe is connected in suction port.

Aforesaid suction tude structure-improved, this second mouth of pipe is connected in engine.

In sum, the utility model can be regulated charge flow rate pressure automatically according to the speed of air-flow, has when promoting horsepower and low speed at a high speed to produce the effect of sinuous flow with fuel saving between inwall.In addition, the protruding wall between above-mentioned conduit is equidistantly alternately, makes air-flow obtain stablizing average transmission between engine and suction port.

Embodiment

A kind of suction tude structure-improved (as shown in Figure 2) that the utility model proposes, that is be a kind of charge flow rate pressure regulating mechanism, it mainly is to establish first mouth of pipe 21 and second mouth of pipe 22 that extends out in a hollow tube 2 two ends symmetrical rings, use and connect suction port and engine respectively, wherein the inwall 3 of this hollow tube 2 is equipped with a plurality of protruding walls 23 that are unidirectional radial arrangement mutually and (please cooperates and consult Fig. 3 A, shown in the 3B), respectively form helical conduit 24 in 23 on protruding wall, in addition should respectively have first retaining wall 211 and second retaining wall 221 with conduit 24 two ends by protruding wall 23, and this first grade of wall 211 and the second retaining wall 221 oblique cambered surface 212 of formation respectively and between the ora terminalis of first mouth of pipe 21 and second mouth of pipe 22,222.

The protruding wall 23 that wherein said conduit is 24 is equidistantly alternately, and mat makes air-flow obtain stablizing average transmission between engine and suction port.

By said structure, promptly when engine during in top gear (seeing also shown in Fig. 2,4), this input air current A is concentrated the center that enters hollow tube 2 by first mouth of pipe 21, seeing through rifling more directly advances principle and is directly discharged by second mouth of pipe 22 and form output gas flow B and enter engine and fuel mix, and cooperate in these hollow tube 2 inwalls 3 and be equipped with the protruding wall 23 that is unidirectional radial arrangement mutually, make this air-flow can be, to reach the purpose that soups at a high speed in protruding wall 23 superchargings.

In addition if engine (sees also Fig. 2 when bottom gear, shown in 5), because air-flow velocity is more slow, therefore after the input air current A sees through oblique cambered surface 212 collections of first mouth of pipe 21, promptly be spread in the helical conduit 24 of 23 on the protruding wall of hollow tube 2 inwalls 3 because of retention effect, and be directed to second mouth of pipe 22 along this helical conduit 24 and form output gas flow B, produce sinuous flow in 3 of inwalls, to hinder flowing to of air-flow, the fuel feeding sensor (figure does not show) that makes engine is because of induction pressure, the reduction of flow and flow velocity, and reduce fuel delivery relatively, to reach the purpose of fuel saving, and the oblique cambered surface 222 that sees through second mouth of pipe 22 again makes the concentrated engine that is released into of this air-flow, by rich oil phenomenon (being oil/gas proportions of ingredients overgauge value), to reach the purpose that low speed promotes torsion, mat makes hollow tube 2 of the present utility model regulate charge flow rate pressure automatically according to the speed of air-flow, to reach the effect that promotes horsepower and low speed fuel saving at a high speed, has convenient and practical property.

In sum, the utility model is in order to promote the engine fuel utilization benefit, and a kind of preferable feasible suction tude structure-improved is provided, and uses to reach can promote horsepower and in the effect of low speed fuel saving when high speed.

Only the above only is of the present utility model one preferable possible embodiments, non-so limit to claim of the present utility model, so use the utility model specification and diagramatic content such as or do not take off the equivalent structure that its skill spirit is done, directly or indirectly apply to other correlative technology field person, all in like manner all ought to be contained in the scope of spiritual category of the present utility model, and close and give Chen Ming.
