This inlet manifold structural design is reasonable, the phenomenon of leaking gas can not appear.

Description

Motor intake manifold

Technical field

This utility model belongs to diesel-engine equipment technical field, is related to a kind of motor intake manifold.

Background technology

In engine art, inlet manifold is one of vital part therein, and its major function is for each cylinder of electromotor There is provided sufficient and uniform gaseous mixture, therefore, inlet manifold is the key factor of impact engine power performance.Traditional air inlet discrimination The structure of pipe is in the form of each air intake branch is respectively arranged, and becomes one, pressure stabilizing cavity is less at air inlet, this kind of Complex structure, easily causes cylinder admission pressure maldistribution.Existing inlet manifold in structure design, using entering QI KOU is be arranged in parallel with manifold body surface, when mounted, by bend pipe, air inlet is connected with the gas outlet of air inlet tube, Lead to attachment structure complex, be easily caused gas leak phenomenon.

Content of the invention

This utility model is directed to the problems referred to above, provides a kind of motor intake manifold, this inlet manifold reasonable in design, It is not in gas leak phenomenon.

According to the technical solution of the utility model：A kind of motor intake manifold it is characterised in that：Including manifold body, Manifold body is internally formed air cavity, and manifold body top surface arranges air inlet tube interface, and manifold body sidepiece arranges the first menifold and goes out Mouth, the second manifold outlet, the 3rd manifold outlet, the 4th manifold outlet, described air inlet tube interface, the first manifold outlet, second Manifold outlet, the 3rd manifold outlet, the 4th manifold outlet all connect air cavity, setting the wherein on air inlet tube interface end flanges One reinforcing prop, the first reinforcing prop arranges bolt hole, described manifold body corresponds in the plane that air inlet tube interface is located Setting mounting seat.

As further improvement of the utility model, groove is set between two neighboring manifold outlet, described groove is circle Arc groove.

As further improvement of the utility model, described mounting seat arranges small one and large one two connecting holes.

As further improvement of the utility model, described manifold body arranges the second reinforcing prop, the second reinforcing prop passes through Wear manifold body, the second reinforcing prop arranges bolt hole.

Of the present utility model have technical effect that：This utility model product structure is simple, rationally ingenious, for existing product In the course of the work, it is susceptible to the problem of gas leakage at faying face and specially design；Air inlet tube interface is obliquely designed, When realizing manifold body and being connected with air inlet tube, syphon shape connector that need not be extra, realize compact conformation rationally, subtract simultaneously Few connector is it is also possible to guarantee that sealing property is reliable, it is to avoid gas leak phenomenon；In this utility model product, the reinforcing prop of setting is permissible Effectively improve the intensity of inlet manifold；Between adjacent manifold outlet, the arc groove of setting, had both improved the strong of gas inlet menifold Degree, reduces gas flow resistance again, effectively improves work efficiency.

Brief description

Fig. 1 is axonometric chart of the present utility model.

Fig. 2 is front view of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is further described.

Fig. 1, in 2, including manifold body 1, air inlet tube interface 2, the first manifold outlet 3, the second menifold interface the 4, the 3rd Menifold interface 5, the 4th menifold interface 6, the first reinforcing prop 7, groove 8, mounting seat 9, second reinforcing prop 10 etc..

As shown in Figure 1, 2, this utility model is a kind of motor intake manifold, including manifold body 1, in manifold body 1 Portion forms air cavity, and manifold body 1 top surface arranges air inlet tube interface 2, and manifold body 1 sidepiece arranges the first manifold outlet 3, second Manifold outlet 4, the 3rd manifold outlet 5, the 4th manifold outlet 6, described air inlet tube interface 2, the first manifold outlet 3, the second qi Pipe exports the 4, the 3rd manifold outlet 5, the 4th manifold outlet 6 all connects air cavity, arranges wherein on air inlet tube interface 2 end flanges First reinforcing prop 7, the first reinforcing prop 7 arranges bolt hole, described manifold body 1 corresponds to what air inlet tube interface 2 was located Mounting seat 9 is arranged on plane.

Groove 8 is set between two neighboring manifold outlet, and described groove 8 is arc groove.The design of arc groove decreases The use of material, saves production cost；Arc groove design simultaneously also effectively increases drafting efficiency, and arc groove design can To avoid stress concentration, improve the bulk strength of inlet manifold.

Small one and large one two connecting holes are arranged on mounting seat 9, the plane of the manifold body 1 that mounting seat 9 is located with it is in water Flat-shaped.

Second reinforcing prop 10 is arranged on manifold body 1, the second reinforcing prop 10 runs through manifold body 1, on the second reinforcing prop 10 Setting bolt hole.

Work process of the present utility model is as follows：This utility model product structure advantages of simple, when using, by air inlet connecting The outlet of interface tube 2 and air inlet tube is connected, because air inlet tube interface 2 is using bending design, bridge piece that need not be extra, Directly can be connected with air inlet tube outlet, thus realize manifold body 1 and be directly connected with air inlet tube, middleware Reduce, effectively increase sealing effectiveness, it is to avoid the problem leaking air.
