Accompanying drawing explanation
Also will be described in more detail the utility model with reference to accompanying drawing based on embodiment hereinafter.
Fig. 1 is the structural representation of the inlet manifold assembly of the utility model embodiment.
In the accompanying drawings, identical parts use identical reference character.Accompanying drawing is not according to the scale of reality.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, inlet manifold assembly 1 of the present utility model is for flexible fuel engine.Inlet manifold assembly 1 comprises the intake manifold arm 11 that is provided with air outlet slit 111 and seals the rock gas air inlet pipe nipple 12 be arranged on the air flue tube wall of intake manifold arm 11.The middle part of rock gas air inlet pipe nipple 12 is provided with through hole, to form path.When needs input such as rock gas in flexible fuel engine, rock gas air induction hose (not shown) is fixed on rock gas air inlet pipe nipple 12 by such as clip.And rock gas air induction hose is communicated with intake manifold arm 11 by the path on rock gas air inlet pipe nipple 12.In flexible fuel engine working procedure, rock gas flows through rock gas air induction hose, rock gas air inlet pipe nipple 12 and intake manifold arm 11 successively and enters in the firing chamber of flexible fuel engine.After being provided with rock gas air inlet pipe nipple 12, directly rock gas air induction hose is fixed on rock gas air inlet pipe nipple 12, make intake manifold arm 11 and natural gas system easy to connect, and structure is simple, easy to use, save trouble and labor.
When arranging rock gas air inlet pipe nipple 12, rock gas air inlet pipe nipple 12 and intake manifold arm 11 integrated injection molding can be made.Like this, easy to process, be convenient to batch production, improve the connectivity robustness between rock gas air inlet pipe nipple 12 and intake manifold arm 11, thus improve the safety in utilization of rock gas air inlet pipe nipple 12, and when rock gas air inlet pipe nipple 12 is with intake manifold arm 11 integrated injection molding, the sealability between rock gas air inlet pipe nipple 12 and intake manifold arm 11 effectively can also be ensured.
The quantity of intake manifold arm 11 can be identical with the cylinder number of flexible fuel engine.When the cylinder number of flexible fuel engine is multiple, intake manifold arm 11 also arranges multiple.In one example in which, flexible fuel engine is four cylinder flexible fuel engines, and now intake manifold arm 11 is also provided with four.The firing chamber of the corresponding flexible fuel engine of one of them intake manifold arm 11.When being provided with multiple intake manifold arm 11, each intake manifold arm 11 is provided with rock gas air inlet pipe nipple 12.When connecting rock gas air induction hose, each rock gas air inlet pipe nipple 12 all arranges the branch road of a rock gas air induction hose.The amount of natural gas entering each intake manifold arm 11 can be made so all roughly the same, thus make the amount of natural gas of the firing chamber entering each flexible fuel engine also all roughly the same.
When arranging rock gas air inlet pipe nipple 12, rock gas air inlet pipe nipple 12 is arranged on the position of the air outlet slit 111 near intake manifold arm 11.That is, relative to the position of the air intlet of cylinder cap intake duct, rock gas air inlet pipe nipple 12 is more near the position of the air outlet slit 111 of intake manifold arm 11.Larger in the space of the position of the air outlet slit 111 near intake manifold arm 11, be convenient to arrange rock gas air inlet pipe nipple 12, and when being arranged on rock gas air inlet pipe nipple 12 near the air outlet slit 111 of intake manifold arm 11 position, the distance of rock gas air inlet can be reduced, improve and spray accuracy.
In addition, (not shown) can also be connected with rock gas guide rail at the other end of rock gas air induction hose.When needs use rock gas, by opening rock gas guide rail, the path of rock gas is made to be in opening state.When not needing to use rock gas, by closing rock gas guide rail, the path of rock gas is made to be in closed condition.When being provided with rock gas guide rail, facilitate the switching of the materials of flexible fuel engine.
Inlet manifold assembly 1 also comprises the natural gas pressure-reducing valve pipe nipple 13 for connecting natural gas pressure-reducing valve.Natural gas pressure-reducing valve is communicated with intake manifold, to enable vacuum Real-time Feedback in intake manifold to natural gas pressure-reducing valve, thus meets rock gas air inlet duty requirements.After being provided with natural gas pressure-reducing valve pipe nipple 13, conveniently connect natural gas pressure-reducing valve, structure is simple, easy to use, save trouble and labor.
In addition, inlet manifold assembly 1 comprises and the pressure stabilizing cavity 15 being connected intake manifold arm 11 and the throttle body mounting flange 14 be arranged on transition distance.When being provided with multiple intake manifold arm 11, multiple intake manifold arm 11 is connected with pressure stabilizing cavity 15 respectively.That is, air first entered in pressure stabilizing cavity 15 through excessive distance before entering intake manifold arm 11, and then flowed into each intake manifold arm 11 from pressure stabilizing cavity 15.When arranging natural gas pressure-reducing valve pipe nipple 13, natural gas pressure-reducing valve pipe nipple 13 can be arranged between throttle body mounting flange 14 and pressure stabilizing cavity 15.Setting like this, can make the sensitivity of natural gas pressure-reducing valve higher, makes the pressure feedback of natural gas pressure-reducing valve accurate.
Further, when arranging natural gas pressure-reducing valve pipe nipple 13, can by natural gas pressure-reducing valve pipe nipple 13 and inlet manifold assembly integrated injection molding, so that arrange, simplified structure, and the sealing and the Security that improve natural gas pressure-reducing valve pipe nipple 13.
Although be described the utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristics mentioned in each embodiment all can combine in any way.The utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technological schemes fallen in the scope of claim.
