Abstract
The utility model provides an intake manifold for a diesel engine, relating to the technical field of automobile engines. The intake manifold comprises an air inlet, an upper shell of the intake manifold and a lower shell of the intake manifold, wherein the lower shell of the intake manifold is fixedly arranged below the upper shell of the intake manifold in a vibration welding way; and the air inlet is arranged above the upper shell of the intake manifold and forms an integrated structure with the intake manifold. The intake manifold is characterized in that the upper shell of the intake manifold is a whole cavity, and has the benefits that the traditional design of an intake branch pipe is abandoned; four intake passages are integrated into a whole chamber, so that the pressure stabilizing effect is improved greatly, the intake pressure of each cylinder is uniformly distributed, the structure of an internal chamber is simpler, and the manufacturing process is simplified.
Description
Technical field
The utility model relates to technical field of automobile engine, relates in particular to a kind of diesel engine intake manifold.
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 become one (as shown in Figure 1) at the suction port place, pressure stabilizing cavity is less, this kind complex structure, cause cylinder suction pressure maldistribution easily, and intake manifold adopts metallic material usually, makes that the quality of intake manifold own is heavier, and shock resistance, heat resistance and hot ageing stability are low.
Summary of the invention
The purpose of this utility model is at top described defective, provides a kind of simple in structure, the diesel engine intake manifold of cylinder suction pressure distributed uniform.
For realizing top described purpose, the utility model is achieved by the following technical solutions.
A kind of diesel engine intake manifold, comprise suction port, intake manifold upper casing and intake manifold lower casing, the intake manifold lower casing is fixedly installed in intake manifold upper casing below by the mode of Vibration Welding, suction port is positioned at intake manifold upper casing top, form integrative-structure with the intake manifold upper casing, wherein, the as a whole cavity of described intake manifold upper casing.
The O RunddichtringO is installed on the described suction port.
On the described intake manifold lower casing rectangular seal is installed.
On the described intake manifold lower casing intake manifold construction bolt is installed.
The air inlet tube construction bolt is installed on the described suction port.
The material of described intake manifold adopts Reinforced Nylon 6 resin and plastics.
The beneficial effects of the utility model are: the air intake branch design of intake manifold abandoning tradition of the present utility model, four intake ducts are made the cavity of an integral body, the not only big raising of voltage regulation result, each cylinder suction pressure distributed uniform, and inner-cavity structure is more simple, has simplified manufacturing process.The utility model changes Reinforced Nylon 6 resin and plastics into by traditional metallic material, not only alleviated the quality of intake manifold, and very big contribution is arranged to alleviating the motor gross mass, make the utility model good heat resistance, dimensionally stable, mechanical strength height, hot ageing stability is good, can reduce gas-flow resistance, satisfies the various operating conditionss of diesel engine, and in transportation process, also be difficult for the distortion of colliding with, and then reduce the part of damage probability.Air inlet tube construction bolt and intake manifold construction bolt and intake manifold are mounted to one, have reduced the motor installation time.
