Abstract

The utility model discloses a cylinder head with an inlet manifold. The cylinder head comprises a cylinder head body (10), wherein the cylinder head body (10) is provided with a plurality of air inlet channels (11) and is connected with an inlet manifold (20); the inlet manifold (20) is provided with a plurality of inlet manifold channels (21); each inlet manifold channel (21) is communicated with a corresponding air inlet channel (11) of the cylinder head body (10); and the cylinder head body (10) and the inlet manifold (20) is integrally cast and molded. By the cylinder head, the air tightness is high, the parts are reduced, and the assembling processes are reduced.

Description

The cylinder cap that has intake manifold

Technical field

The utility model relates to technical field of engines, specifically is the cylinder cap that has intake manifold.

Background technique

Engine performance depends primarily on three aspects, is respectively air inflow, combustion thermal efficiency and mechanical efficiency, and the factor that wherein influences air inflow is except the physical dimension of intake and exhaust pipeline; The most important thing is to guarantee the gas tightness of intake and exhaust pipeline as far as possible, could guarantee like this to continue pressure, could guarantee enough air inflows; Existing intake manifold and cylinder cap body are split type, and each passway of intake manifold is respectively equipped with flange, and flange is tightened each suction port that is fixed in the cylinder cap body through bolt; Each intake manifold passage is connected with the corresponding gas-entered passageway of cylinder cap body, and the existing this following deficiency of cylinder cap ontological existence that has intake manifold: intake manifold passage and cylinder cap body adopt bolt to tighten sealing, can cause poorly sealed like this; The problem that can have gas leakage; Cause engine performance to descend, after especially long-term the use, bolt is loosening easily; Can make the gas leakage problem more serious like this, cause the further decline of engine performance; And poorly sealed meeting is flow backwards waste gas and is discharged into the air that depollutes in the atmosphere; Split type cylinder cap body and intake manifold need be assembled simultaneously, also need use parts such as bolt, makes number of components and parts many, and commentaries on classics allotment of labor preface is loaded down with trivial details, makes the production efficiency of assembling not high.

The model utility content

The utility model technical problem to be solved is to provide to make the cylinder cap that has intake manifold that gas tightness is good, amount of parts reduces, assembly process reduces.

For solving the problems of the technologies described above; The cylinder cap that has intake manifold that the utility model provides; Comprise the cylinder cap body, the cylinder cap body is provided with a plurality of gas-entered passageways, and each gas-entered passageway is connected to cylinder with a cylinder of motor respectively and imports air; The cylinder cap body is connected with intake manifold; Intake manifold is provided with a plurality of intake manifold passages, and each intake manifold passage is connected with the corresponding gas-entered passageway of cylinder cap body, and the intake manifold passage is that the gas-entered passageway of the cylinder cap body that is connected imports air; The air of intake manifold passage is flowed into by the suction port of intake manifold; Described cylinder cap body and intake manifold are the overall structure of casting integrated moulding, that is to say that the gas-entered passageway of cylinder cap body and the joint of intake manifold passage need not pass through bolt, and the gas-entered passageway of cylinder cap body and intake manifold passage are one-body molded through die casting to be a complete passage.

After adopting above structure, the utility model compared with prior art has following advantage:

The structure that cylinder cap body and intake manifold are formed in one has been avoided the problem of leaking gas between gas-entered passageway and the intake manifold passage of cylinder cap body fully, and gas tightness is good; Can guarantee the air inflow that cylinder is enough; Make engine performance stable, and do not need links such as flange, bolt, nut, amount of parts is reduced; And saved this one procedure of cylinder cap body and intake manifold assembling, manufacturing efficiency is improved.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.

The structural representation that is had the cylinder cap of intake manifold by Fig. 1, the utility model shown in Figure 2 can be known; It comprises cylinder cap body 10; The motor of these cylinder cap body 10 corresponding four cylinders; Air outlet 12 and a cylinder that cylinder cap body 10 is provided with 11, one gas-entered passageways 11 of four gas-entered passageways are connected to its importing air, and cylinder cap body 10 is connected with intake manifold 20; Intake manifold 20 is provided with four intake manifold passages 21; Each intake manifold passage 21 is connected with a corresponding gas-entered passageway 11 of cylinder cap body 10, and intake manifold 20 also is provided with suction port 22, and air imports intake manifold by suction port 22; Air is shunted by four intake manifold passages 21 after importing intake manifold by suction port 22; Air flows into the gas-entered passageway 11 of the cylinder cap body 10 that is connected with intake manifold passage 21 accordingly respectively from four intake manifold passages 21, described cylinder cap body 10 is the overall structure of casting integrated moulding with intake manifold 20, that is to say that cylinder cap body 10 and intake manifold 20 directly form an integral body through casting; The gas-entered passageway 11 of cylinder cap body 10 need not pass through bolt with the joint of intake manifold passage 21; The gas-entered passageway 11 of cylinder cap body 10 and intake manifold passage 21 be casting integrated to be shaped to a complete passage, and the centre does not have junction surface, has avoided the problem of original intake manifold passage 21 and the gas-entered passageway 11 joints gas leakage of cylinder cap body 10 fully.

Below only use preferable instance with regard to the utility model and made explanation, but can not be interpreted as it is the restriction to claim, the structure of the utility model can have other variations, is not limited to said structure.In a word, the various variations of being done in the protection domain of all independent claims at the utility model are all in the protection domain at the utility model.
