Abstract
The utility model discloses a combination of an automobile engine cylinder head and an inlet manifold. The combination of the automobile engine cylinder head and the inlet manifold comprises the cylinder head and the inlet manifold, wherein the cylinder head and the inlet manifold are connected in an integrated mode. Compared with the prior art, the engine cylinder head and the inlet manifold are combined into a whole, and therefore the sealing performance between the engine cylinder head and the inlet manifold is greatly improved, and the weight of a whole engine is lowered. Besides, dissolution, gold type hostling, casting and machining are only needed once to obtain a finished product. The dissolution of the inlet manifold, the gold type hostling, the casting and the machining technique and the assembling technique are not needed any more, an assembling technique between a bolt and a sealing pad is also spared, the manufacturing technique is greatly simplified, and the production cost is lowered.
Description
Technical field
The utility model relates to the assemblying body of a kind of automobile engine cylinder head and intake manifold.
Background technique
Engine cylinder cover is the vitals of motor car engine, its top is equipped with camshaft, bottom and engine cylinder-body, piston form the firing chamber, both sides are admission line and exhaust duct, be connected with the gas exhaust manifold that scavenges with the intake manifold that enters oil gas respectively, in cooling water channel and the lubricating oil path that runs through arranged.Therefore engine cylinder cover plays very important effect to the power of motor and the impact of service behaviour.When combustion gas in the firing chamber during detonation, gas temperature moment is up to more than 1100 ℃, this high temperature thermal shocking repeated action produces up to 7MPa pressure, and this pressure directly acts on the joint of engine cylinder cover and cylinder body, and the operating conditions of visible engine cylinder cover is very abominable.
When therefore engine cylinder cover being designed, need to consider air flue, the geometrical shape of firing chamber and the whole wall thickness of cylinder cap.From the casting structure of engine cylinder cover, inner-cavity structure is complicated, changeableization of shape, and wall unevenness is even, and Cooling of Cylinder Head water channel inner chamber is having many bends or curves, and wall thickness is generally at 15mm, and thinnest part only has 2.5mm.And along with motor to high efficiency, the future development of low oil consumption, of low pollution, the structure of cylinder cap can become and become increasingly complex, because the particular job conditional request of cylinder cap is very high to the performance requirement of cylinder cap.For example cylinder cap will bear the air tightness test ne-leakage of 0.3 ~ 0.5MPa, intake and exhaust port requires very tight on geometrical shape, it directly affects direction that oil gas enters and mixing situation, engine power, toggle speed, generally all need to carry out runner test check, the cooling water channel shape of cylinder cap inside and volume size are to all having a direct impact the working life of motor.This shows, the Foundry Production technical requirements of automobile engine cylinder head, highly difficult large, the engine cylinder cover mould design and manufacture also is a vital assurance.
Because the thermal conductivity of aluminum alloy is good, is conducive to improve compression ratio, so aluminum alloy cylinder cover is widely used in recent years.Generally speaking, the assemblying body of motor car engine internal engine cylinder cap and intake manifold is the assembly that cylinder cap and intake manifold assemble, the intake manifold body material is cast iron, and engine cylinder cover links to each other by bolt, sealing gasket and intake manifold and is connected into combination.There is following technological deficiency in the assemblying body of such engine cylinder cover and intake manifold:
At first intake manifold is bolted on the cylinder cap, and in a single day the torsion of bolt can not be guaranteed, and then can cause the accidents such as gas leakage, suction tude abnormal vibrations; Secondly the assembling of the assemblying body of engine cylinder cover and intake manifold requirement is higher, and intake manifold, intake manifold sealing gasket, cylinder cap attachment face all require good planeness and surface quality, if there is phenomenons such as scuffing, sand holes, and easily gas leakage; The assemblying body complex manufacturing of engine cylinder cover and intake manifold again, cost of production is higher, and generally speaking, engine cylinder cover, intake manifold and sealing gasket need to assemble after the casting respectively again.Whole process is as follows: reorganize and outfit, cast, process and to get cylinder cap through dissolving, golden type, intake manifold also will be through dissolving, golden type reorganize and outfit, cast, process and make, and the cylinder cap of machine shaping and intake manifold are assembled together with bolt, compression spring and sealing gasket again; At last, the connected elements such as bolt, sealing gasket are more, and the intake manifold body material is cast iron, and this all causes engine weight larger, and fuel consumption is large.In addition, because the various factors in processing and when assembling always makes both produce defective in cohesive process, the junction plane gas leakage that causes such as the quality of attachment face does not reach technical requirements, thus can reduce sealability between cylinder cap and the intake manifold.
The model utility content
Technical problem to be solved in the utility model provides the assemblying body of a kind of automobile engine cylinder head and intake manifold, to improve the sealability between engine cylinder cover and the intake manifold.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: the assemblying body of a kind of automobile engine cylinder head and intake manifold, comprise cylinder cap and intake manifold, and described cylinder cap is that integral type is connected with described intake manifold.
The material of described cylinder cap and described intake manifold is aluminum alloy.
The utility model adopts technique scheme, compared with prior art, engine cylinder cover and intake manifold are combined as a whole, improved greatly the sealability between engine cylinder cover and the intake manifold, also reduced the weight of whole motor, and only need to be through once dissolving, golden type are reorganized and outfit, cast, processed and can obtain finished product when producing, need no longer that the dissolving of intake manifold, golden type are reorganized and outfit, casting, processing technology and assembly technology, also saved the assembly technology between bolt, the sealing gasket, greatly simplify production technology, reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the assemblying body of automobile engine cylinder head of the present utility model and intake manifold;
Mark among the above-mentioned figure is: 1, intake manifold; 2, cylinder cap.
Embodiment
As shown in Figure 1, the assemblying body of a kind of automobile engine cylinder head of the utility model and intake manifold, comprise cylinder cap 2 and intake manifold 1, in order to solve problems of the prior art, the cylinder cap 2 of this assemblying body and intake manifold 1 are for integral type is connected, and intake manifold 1 is stretched out from the top of cylinder cap 2 and be crooked around the side to cylinder cap 2.Compared with prior art, engine cylinder cover 2 and intake manifold 1 are combined as a whole, improved greatly the sealability between engine cylinder cover 2 and the intake manifold 1, also reduced the weight of whole motor, and only need to be through once dissolving, golden type are reorganized and outfit, cast, processed and can obtain finished product when producing, need no longer that the dissolving of intake manifold 1, golden type are reorganized and outfit, casting, processing technology and assembly technology, also saved the assembly technology between bolt, the sealing gasket, greatly simplify production technology, reduced cost of production.
The material of cylinder cap 2 and intake manifold 1 is aluminum alloy, and with the moulding of aluminum alloy one-step casting, motor complete machine weight has reduced many, thereby has reduced the oil consumption of automobile.
