Do you know about the Active Grille Shutter ?

The ”active” grille means that the horizontal or vertical grille bars on the center grid can be rotated by means of a modular control, in short, each bar is connected to the other by means of a linkage, which is controlled by an electric motor that is driven by a control unit to twist the grille bars.

The air intake grille of ordinary vehicles is the most common plastic parts, the spacing distance between the partitions, the angle of the grille plate is fixed, squeezing the air in the front of the car during driving can let the airflow formed in accordance with the fixed guide into the engine compartment.

The active grille shutter opens the vents during operation if air is needed to cool the engine. If no airflow is needed, the vents are closed, significantly reducing air resistance and allowing the engine to reach its most efficient operating temperature more quickly. This also contributes to lower fuel consumption and reduces CO2 emissions by approximately 2%.

When the vehicle is started, the vanes open and close, then return to the position required for the condition. The blades are located behind the bumper to prevent damage. When parked, the vanes open to prevent them from remaining closed due to malfunction.

The grille mounted in front of the radiator is controlled by the module to rotate movable grilles that can block or pass airflow. The control module can be placed in a number of positions from fully closed to fully open depending on the amount of cooling air required by the condenser and radiator.

In summary, the active grille shutter is a significant improvement over the traditional front grille found in most vehicles. It allows for greater control over the airflow into the engine compartment, resulting in more efficient cooling, lower fuel consumption, and reduced CO2 emissions. This technology is becoming increasingly popular in the automotive industry and is expected to become a standard feature in many vehicles in the future.
