Abstract
The utility model discloses a plastics air intake manifold for CNG engine, connect including air intake manifold body and CNG injection pipe, be provided with rotatory welded seat on the air intake manifold body, the CNG jet orifice has been offered at rotatory welded seat's middle part, and the spin welding is passed through on rotatory welded seat to one end that the CNG injection pipe connects, and the CNG injection pipe connects the air flue intercommunication that the center -aisle passes through CNG jet orifice and air intake manifold body, and another pot head that the CNG injection pipe connects has rubber end cap, rubber end cap and CNG injection pipe joint interference fit. The utility model discloses process when having simplified repacking CNG equipment has promoted the repacking reliability.
Description
Technical field
The utility model relates to automotive engine component, more specifically to a kind of plastic air intake manifold for CNG motor.
Background technique
Burning CNG(compressed natural gas) the vehicle vehicle of comparing burns gasoline there is better Economy and lower discharge, get more and more applications now.The vehicle of exploitation burning CNG goes on the market vehicle directed exploitation when having a demand in market often, and due to plastic air intake manifold change cost, to compare cylinder cap lower, and therefore burn CNG vehicle normally integrated CNG injection pipe joint on plastic air intake manifold.See Fig. 3, existing technological scheme is integrated boss 21 on plastic air intake manifold body 2, and when vehicle refitting CNG, at boss 21, tapped hole is got at place, is coated with by metal CNG injection pipe joint 3 after spreading sealer and is screwed in tapped hole.Prior art repacking complex procedures, large to plastic air intake manifold damage, poor reliability.
Summary of the invention
The purpose of this utility model is to provide a kind of plastic air intake manifold for CNG motor, and it can simplify operation when reequiping CNG equipment, promotes repacking reliability.
Plastic air intake manifold for CNG motor described in the utility model, comprise intake manifold body and CNG injection pipe joint, intake manifold body is provided with Spin welding joint chair, the middle part of Spin welding joint chair offers CNG spray-hole, one end of CNG injection pipe joint by spin welding on Spin welding joint chair, CNG injection pipe joint center-aisle is communicated with the air flue of intake manifold body by CNG spray-hole, the other end cover of CNG injection pipe joint has rubber plug, rubber plug and CNG injection pipe joint interference fit.
Plastic air intake manifold for CNG motor described in the utility model, by spin welding between intake manifold body and CNG injection pipe joint, ensure that the sealing of this joint.CNG injection pipe joint center-aisle is communicated with the air flue of intake manifold body by CNG spray-hole, meets CNG gas eject request.Rubber plug is assembled on CNG injection pipe joint in interference mode, ensures the sealing demand of the series of experiments before vehicle CNG reequips.Rubber plug, when carrying out CNG repacking, only need be pulled down, the CNG injection pipe joint on each air flue connects CNG injection pipe by vehicle, and it is good to reequip simple and reliable property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cut-away view along XX line in Fig. 1;
Fig. 3 is the structural representation of the existing plastic air intake manifold for CNG motor.
Embodiment
In order to explain the technical solution of the utility model further, below in conjunction with accompanying drawing, the utility model is elaborated.
Shown in Fig. 1 and Fig. 2, for the plastic air intake manifold of CNG motor, comprise intake manifold body 2 and CNG injection pipe joint 3, intake manifold body 2 is provided with Spin welding joint chair 24, the middle part of Spin welding joint chair 24 offers CNG spray-hole 23, one end of CNG injection pipe joint 3 by spin welding on Spin welding joint chair 24, CNG injection pipe joint center-aisle 31 is communicated with the air flue 22 of intake manifold body 2 by CNG spray-hole 23, the other end cover of CNG injection pipe joint 3 has rubber plug, rubber plug and CNG injection pipe joint interference fit.Described CNG injection pipe joint 3 is bent, and the angle of CNG injection pipe joint bending can adjust according to concrete arrangement.When vehicle carries out CNG repacking, rubber plug 4 is pulled out, connects corresponding CNG injection pipe.
