Abstract
The utility model discloses an engine air intake manifold which comprises a voltage-stabilized cavity, an air intake bent pipe and an installation seat, wherein one end of the voltage-stabilized cavity is provided with an air inlet, an air throttle body flange surface is arranged at the air inlet of the voltage-stabilized cavity, an air outlet is arranged on the installation seat, and the outlet of the installation seat is provided with an engine throttle body flange surface. The engine air intake manifold is characterized in that the integral body of the air intake manifold is formed through the connection of a first piece portion and a second piece portion. By adopting the structure, the engine air intake manifold has the advantages of few manufacturing procedures, low cost, high rate of manufacturing finished products and small weight.
Description
Technical field
The utility model relates to technical field of automobile engine, particularly a kind of engine intake manifold.
Background technique
At present, the intake manifold of using on the motor car engine is generally aluminum alloy material and makes, and also needs secondary operations after the intake manifold integral cast moulding of aluminum alloy mechanism, has increased manufacturing process, and manufacture cost is higher.The integral cast structure of this intake manifold easily makes product form sand holes, bubble etc., influences the up-to-standard rate of product.And the aluminum alloy air inlet manifold quality is heavier, its inner wall coarse, and the inlet stream dynamic resistance is big.
The model utility content
The utility model provides a kind of engine intake manifold, can once-through to reach intake manifold, and can reduce manufacture cost, and reduce intake manifold weight, improve the purpose of product qualified rate.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine intake manifold, comprise pressure stabilizing cavity, intake elbow and fitting seat, one end of pressure stabilizing cavity is provided with suction port, pressure stabilizing cavity is provided with the throttle body flanged surface at the suction port place, fitting seat is provided with the air outlet, and fitting seat is provided with engine air admittance door flanged surface at air outlet place, it is characterized in that: described intake manifold integral body is connected and composed by first and second two-part.
A kind of engine intake manifold is characterized in that: described first is to be connected along its curved profile that coincide mutually with second.
A kind of engine intake manifold is characterized in that: described throttle body flanged surface is provided with first seal ring.
A kind of engine intake manifold is characterized in that: described engine air admittance door flanged surface is provided with second seal ring.
A kind of engine intake manifold is characterized in that: described intake elbow is provided with the nut with stiffening rib on the outer surface in its bending part.
A kind of engine intake manifold is characterized in that: described intake elbow is provided with a shackle member, and shackle member comprises a connecting sheet and the convex body that is arranged on the connecting sheet, and the both sides of convex body are equipped with chute.
A kind of engine intake manifold is characterized in that: described intake manifold integral body is that plastics constitute.
A kind of engine intake manifold has adopted said structure, can once-through when producing, reduced operation, the intake manifold that plastics are made than the reduction of aluminum alloy material manufacture cost, reduced overall weight.When the integral cast of intake manifold, be difficult for simultaneously forming sand holes, bubble etc., improved the up-to-standard rate of finished product, and the plastic air intake manifold inner wall smooth, the inlet stream dynamic resistance is little like this, thereby reduces noise.
