[0002] Active air intake grilles have the advantages of reducing wind resistance, quick warm-up, and improving fuel economy. In recent years, many high-end luxury models have begun to be equipped with active air intake grilles. For models with active air intake grilles, how to design and arrange the air intake channel of the engine intake system becomes the primary issue to be considered. If the air intake channel is not arranged reasonably, it will lead to insufficient engine air intake, increased air intake resistance, and reduced engine performance.

[0003] At present, the conventional air intake system layout scheme for vehicles with active air intake grilles is that the air filter air intake absorbs fresh air from behind the active air intake grille blades, that is, an air intake channel is designed behind the active air intake grille blades to connect to the air filter air intake. When the active air intake grille blades are completely closed, the engine's air intake flow is completely dependent on the air leakage from the active air intake grille window. However, the vehicle often has high requirements for wind resistance and will not make the air leakage of the active air intake grille very large, which will lead to insufficient air intake, unstable cooling, and reduced performance of the engine under certain high-power conditions.
