What is the Function of Active Grille Shutters?
2 Answers
The function of active grille shutters is for heat dissipation and air intake. When the engine radiator's water temperature is too high and natural airflow alone cannot provide sufficient cooling, the fan will automatically activate to assist in heat dissipation. As the vehicle moves, air flows backward, and the fan's airflow direction is also backward. The heated airflow after cooling exits from the area near the windshield at the rear of the engine hood and flows downward from the vehicle, allowing the heat to be discharged. Below is additional information about grille shutters: Advantages: When the vehicle is in a cold state, the grille shuts, helping the engine quickly reach an optimal temperature. Improves fuel economy: When the grille opens, it not only aids in heat dissipation but also reduces air resistance to some extent, thereby improving fuel economy.
The active grille is essentially the part of the car's front fascia that can open and close automatically, and it plays a significant role, especially in my daily driving. When I drive a hybrid sedan, I notice that at high speeds, the grille closes automatically to reduce wind resistance, making the car glide as smoothly as if it were on ice, which significantly lowers fuel consumption and saves me a lot on gas. On cold days when I start the car, it closes to help the engine warm up faster, reducing the warm-up time, so I don’t have to wait too long for the heater to kick in during winter. With gas prices so high these days, these small details really help me save money, and I’ve also heard it can reduce some noise, making the cabin quieter. Overall, it’s like a smart butler, automatically adjusting airflow to improve overall driving efficiency—a pretty thoughtful design.
