Description

Technical Field

[0001] The invention belongs to the technical field of automobile engine intake manifold equipment, and in particular relates to a novel supercharged intake manifold assembly. Background Art

[0002] As a crucial component of the intake system, the intake manifold's structure, shape, and airway dimensions significantly impact engine performance, including charging efficiency, intake resistance, and intake uniformity across cylinders. This in turn influences various aspects of the engine, including power, fuel economy, and emissions. As engine structures become increasingly complex, intake manifold placement is constrained by surrounding space. Therefore, rationally designing the intake manifold within this limited space to ensure both intake flow and uniformity is crucial. Summary of the Invention

[0003] The purpose of the present invention is to provide a novel supercharged intake manifold assembly that rationally arranges the intake manifold air passage and throttle flange positions in a narrow engine environment, thereby improving intake flow and intake uniformity. The technical solution is as follows: A new type of supercharged intake manifold assembly, characterized by: including an air intake 1, an air intake duct 2, an air outlet flange 3, and a pressure stabilizing chamber 4. The air intake 1 is connected to the pressure stabilizing chamber 4 and is arranged between the third and fourth air intake ducts 2 above the pressure stabilizing chamber. The shorter air intake duct 2 is designed to connect the pressure stabilizing chamber 4 and the air outlet flange 3. Compared with the flat position, the installation point angle of the air intake 1 flange is offset 6° clockwise, which ensures that the throttle body 5 of the intake system component does not exceed the maximum lateral boundary of the engine, and at the same time ensures the wrench space for the screw installation of the air inlet and outlet flanges 3. According to the CFD calculation results, The structure of the fixed intake duct 2 is designed to ensure the intake flow rate and intake uniformity. The air intake 1, the air intake duct 2, the air outlet flange 3 and the pressure stabilizing chamber 4 are covered with an intercooler 6. In order to ensure the overall modality, a bracket 7 is designed to be installed on the cylinder block to support the overall intake system. Due to limited engine space, more brackets cannot be designed below. The left side is designed to have both the functions of a lifting ear and a bracket. The right side is designed to have a bracket 3 10 and a bracket 4 11 fixed on the manifold and the synchronous chain cover. Four brackets are used to jointly ensure the overall modal strength of the intake system.

[0004] The beneficial effects of the present invention are as follows: in a narrow space, the air intake flange is arranged above the intake manifold, and a short air duct is designed to solve the problem of how to arrange the air intake system while avoiding surrounding components when the engine boundary is narrow. At the same time, the intake manifold air duct and each mounting flange are designed according to the position of the air intake flange and the surrounding space, ensuring the intake flow rate and intake uniformity while ensuring the assemblability of the intake manifold.
