Abstract

The utility model relates to a diesel engine air inlet manifold which comprises a manifold shell body, wherein an air inlet is formed in the manifold shell body, an air inner cavity is formed inside the manifold shell body, an opening is formed at the lower portion of the manifold shell body, the opening is communicated with the air inner cavity, and a plurality of first installation screw holes are uniformly formed in the edge of the opening. The diesel engine air inlet manifold is characterized in that the first installation screw holes are formed in strengthening columns, the strengthening columns are fixed on the outer side of a manifold body, and second installation screw holes are formed in the air inlet. According to the diesel engine air inlet manifold, on one hand, a plurality of air channels are combined into a cavity body, so pressure stabilizing effects are improved; and one the other hand, the strengthening columns are arranged on the outer side of the shell body of the air inlet manifold, so the air inlet manifold is firm in structure and long in service life.

Description

The diesel engine intake manifold

Technical field

The utility model relates to a kind of intake manifold, and especially a kind of diesel engine intake manifold belongs to the diesel-engine equipment technical field.

Background technique

In engine art, intake manifold is one of vital part wherein, and its major function is that therefore, intake manifold is the key factor that influences engine power performance for each cylinder of motor provides sufficient mixed gas uniformly.The structure of traditional intake manifold is the form that adopts each air intake branch to arrange respectively, just becomes one at the suction port place, and pressure stabilizing cavity is less, and this kind complex structure causes cylinder suction pressure maldistribution easily.Chinese patent application CN201020627551.8 discloses a kind of diesel engine intake manifold, the air intake branch design of abandoning tradition, four intake ducts are made the cavity of an integral body, not only voltage regulation result improves greatly, the suction pressure distributed uniform, and inner-cavity structure is more simple, has simplified manufacturing process.But the intake manifold of this kind structure has also been brought other problem, owing to four air inlet air flues have been made the cavity of an integral body, the more traditional air inlet cavity of cavity is big, and the manifold intensity that adopts conventional material and explained hereafter to make out can be affected, and more traditional intake manifold of life-span is short.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of diesel engine intake manifold, sound construction, long service life.

The technological scheme that provides according to the utility model, described diesel engine intake manifold, comprise manifold housings, in manifold housings a suction port is set, the inside of manifold housings forms gas lumen, the bottom of manifold housings is uncovered, and this is uncovered to be communicated with gas lumen, evenly arranges a plurality of first at uncovered edge screws are installed; It is characterized in that: described first installs screw is arranged on the reinforcing prop, and this reinforcing prop is fixed in the outside of manifold body.

Described suction port place arranges second screw is installed.

Diesel engine intake manifold described in the utility model is merged into a cavity with a plurality of air flues on the one hand, improves voltage regulation result, and the hull outside in intake manifold is provided with reinforcing prop on the other hand, makes the sound construction of intake manifold, long service life.
