The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, provide a kind of simple and reasonable, be convenient to the space and arrange that processing technology is simple, lightweight, the engine air inlet tube that integrated degree is high.
For achieving the above object, provide a kind of engine air inlet tube according to the utility model, comprising:
The suction tude body, it comprises: the reducing inlet end that is interconnected and dilatation outlet side, the reducing inlet end is round mouth, is positioned at suction tude body front, and its sidewall adopts the boxlike pipe shaft, and the outer end is provided with inlet flange; The dilatation outlet side is positioned at the suction tude body back side, and its outer end is provided with the flange of giving vent to anger;
The common rail pipe installation base, it is laid on the described dilatation outlet side, and lays respectively at the both sides of described reducing inlet end.
In the technique scheme, the common rail pipe installation base is laid in the upside of described dilatation outlet side.
In the technique scheme, inlet flange and the flange of giving vent to anger are rectangle.
In the technique scheme, the rectangular suction tude bolt hole that is laid with on the rectangle inlet flange.
In the technique scheme, the rectangle flange of giving vent to anger adopts the integral expression flange arrangement, and its edge, upper edge is laid with the steam outlet pipe mounting hole at interval.
Compared with prior art, the utlity model has following beneficial effect: this engine air inlet tube is by installing and fixing boss at suction tude upper end integrated high voltage common rail pipe, and with inlet flange and the design of suction tude bolt mounting plane integral type, cancelled the join partition between intake manifold and each the cylinder air flue, making it easy to the space arranges, reduce difficulty of processing, improved lightweight, integrated degree.

Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be benchmark with the direction shown in each figure all, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Engine air inlet tube of the present utility model is simple and reasonable, by installing and fixing boss at suction tude upper end integrated high voltage common rail pipe, and with inlet flange and the design of suction tude bolt mounting plane integral type, cancelled the join partition between intake manifold and each the cylinder air flue, making it easy to the space arranges, reduce difficulty of processing, improved lightweight, integrated degree.
As shown in Figure 1 to Figure 3, the concrete structure of this engine air inlet tube comprises: the suction tude body, and be integrated in common rail pipe installation base 2 on this suction tude body, the suction tude body is installed in and directly is each cylinder air feed on the cylinder head, omitted the intake manifold that is respectively each cylinder air feed, the space of being convenient to motor is arranged, has improved lightweight, integrated degree.
The suction tude body comprises: reducing inlet end 11 and dilatation outlet side 12, and wherein, reducing inlet end 11 is round mouth, is positioned at suction tude body front, its sidewall adopts the boxlike pipe shaft; The outer end is provided with rectangle inlet flange 13, and the rectangular suction tude bolt hole 14 that is laid with on it makes rectangle inlet flange 13 and suction tude bolt mounting plane integral type design, and has simplified the process for machining of whole suction tude body.
As shown in Figure 3, dilatation outlet side 12 is rectangle, be positioned at the suction tude body back side, its inner chamber is communicated with reducing inlet end 11, its outer end is provided with the rectangle flange 15 of giving vent to anger, and the rectangle flange 15 of giving vent to anger adopts the integral expression flange arrangements, and its edge, upper edge is laid with steam outlet pipe mounting hole 16 at interval, cancel the join partition between each cylinder air flue, reduced the weight of whole suction tude body.
As shown in Figure 1, common rail pipe installation base 2 is two, is laid in the upside of dilatation outlet side 12, and lays respectively at the left and right sides of reducing inlet end 11.Suction tude body upper end integrated high voltage common rail pipe installs and fixes boss, avoid designing separately the common rail pipe support, simultaneously, the common rail pipe support is installed in the suction tude top, be conducive to shorten common rail pipe to the high-pressure oil pipe length between the oil sprayer, reduced the long risk that ruptures because of engine luggine of high-pressure oil pipe.
The air inlet of motor enters dilatation outlet side 12 through the reducing inlet end 11 of suction tude body, directly is each cylinder air feed by dilatation outlet side 12, has omitted the intake manifold that is respectively each cylinder air feed.
