Description

A kind of enmgine exhaust Hermetical connecting structure

Technical field

The utility model is related to a kind of enmgine exhaust Hermetical connecting structures.

Background technology

Automobile is the widely used vehicles of modern society, and engine is the core component of automobile, in setting for engine In meter, in order to improve the efficiency of engine, the air inlet pipeline in design for engine is attached great importance to, and has paid attention to air inlet pipeline Each CONSTRUCTED SPECIFICATION, however the connection of exhaust particularly exhaust manifold and the engine gas outlet for engine, for subtracting Few engine space requirement, only considered the firmness of connection, therefore, company is present with after the use that experienced for many years in engine The phenomenon that connecing gas leakage influences the reliability of vehicle and the control of discharge.

The content of the invention

The purpose of this utility model is to provide a kind of enmgine exhaust Hermetical connecting structures, are arranged by rational deployment The layout for the fixing bolt that gas manifold is connected with engine gas outlet improves the leakproofness of exhaust manifold and engine gas outlet Can, overcome the generation for the phenomenon that leaks air after long-time service.

To achieve these goals, the technical solution of the utility model is：A kind of enmgine exhaust is tightly connected knot Structure, the exhaust manifold being connected including engine cylinder cap and with engine cylinder cap, engine cylinder cap include multiple with sending out The corresponding multiple exhaust outlets of motivation number of cylinders, exhaust manifold are connected on multiple exhaust outlets, wherein, in the multiple exhaust outlet Each exhaust port side is respectively arranged with four fixed bolt holes in face of angle, and the exhaust manifold passes through stud and engine Cylinder head connects, and exhaust sealing gasket is provided between exhaust manifold and exhaust outlet, and the exhaust manifold is also connected with booster, Exhaust manifold and connecing also is bolted using diagonal four between booster, in exhaust manifold and is connect and is provided with increasing between booster Densification packing.

Scheme is further：Two of which fixed bolt hole in one four fixed bolt holes of exhaust outlet be and its Shared fixed bolt hole in four fixed bolt holes of adjacent row gas port, two shared fixed bolt holes are arranged on two adjacent rows Between gas port.

Scheme is further：The exhaust manifold and the bolt company for connecing the bolt connection studs between booster Binding structure.

Compared with the prior art, the utility model has the following advantages：

The exhaust manifold material of the utility model uses cast iron, simple for structure, at low cost, exhaust manifold and head exhaust mouth Using ten crosspoint connection schemes, the minimum seal pressure between exhaust manifold and cylinder cap is added, improves cylinder cap and exhaust The leakproofness of manifold enhances the reliability of exhaust system；Also ten crosspoint connection sides are used between exhaust manifold and booster Case adds the minimum seal pressure between exhaust manifold and booster, improves the leakproofness of cylinder cap and exhaust manifold, enhancing The reliability of exhaust system.

The utility model is described in detail with reference to the accompanying drawings and examples.

Specific embodiment

A kind of enmgine exhaust Hermetical connecting structure, as depicted in figs. 1 and 2, the structure include cylinder Lid 1 and the exhaust manifold 2 being connected with engine cylinder cap and the booster being connected with exhaust manifold（Assembly）3, exhaust manifold material Material is cast iron materials, and engine cylinder cap includes multiple multiple exhaust outlets corresponding with cylinder number, four cylinder engine Just just like 4 exhaust outlets shown in Fig. 2, exhaust outlet is that in one plane, exhaust manifold is connected on multiple exhaust outlets, In, each exhaust port side in the multiple exhaust outlet is respectively arranged with four fixed bolt holes 102, the exhaust in face of angle Manifold is connected by stud 3 with engine cylinder cap, and exhaust sealing gasket is provided between exhaust manifold and exhaust outlet 4, exhaust manifold and connecing also is bolted using diagonal four between booster, is provided in exhaust manifold and connecing between booster It is pressurized gasket 5.

In embodiment：Can four fixed bolt holes be set respectively in each exhaust outlet surrounding, as a preferred side Case, in the present embodiment, the two of which fixed bolt hole in one four fixed bolt holes of exhaust outlet is adjacent thereto Shared fixed bolt hole in four fixed bolt holes of exhaust outlet, two shared fixed bolt holes are arranged on two adjacent row gas ports Between, such four cylinder is exactly 10 fixed bolt holes, and the distance controlling at fixed bolt hole and exhaust outlet edge is in 20mm to 30mm Between.

Location control is convenient during in order to install：The exhaust manifold and the bolt connect between booster connect double end spiral shell Bolt can first be screwed in fixed bolt hole the work for playing positioning pin using the bolt of studs by the bolt fastening structure of column With the exhaust manifold then is inserted in fixation again.

Above-mentioned connection structure adds the minimum seal pressure between exhaust manifold and cylinder cap, improves cylinder cap and exhaust discrimination The leakproofness of pipe enhances the reliability of exhaust system；It is cross four point attachment scheme to be used between exhaust manifold and booster, The minimum seal pressure between exhaust manifold and booster is added, the leakproofness of cylinder cap and exhaust manifold is improved, enhances The reliability of exhaust system.Finally it should be noted that：Above example be only to illustrate the technical solution of the utility model rather than It is limited, although the utility model is described in detail with reference to preferred embodiment, the ordinary skill of this field Personnel should be understood：It can still be modified or replaced equivalently the technical solution of the utility model, and these are changed Or equivalent substitution cannot also make the spirit and scope of amended technical solution disengaging technical solutions of the utility model.
