Active Grille Shutter(AGS)


        The Active Grille Shutter (AGS) is an air intake grille adjustment system. By changing the opening and closing angle of the air intake grille, it is possible to control the intake air volume of the engine compartment and the wind resistance of the entire vehicle, thereby realizing the functions of improving the fuel economy of the vehicle and accelerating the engine warm-up process.

        The AGS provided by HiRain Technologies is characterized by its high motion accuracy, high reliability and environmental adaptability. It can support LIN bus input or PWM input. There are two types of GSA-1 and GSA-2 available depending on the output torque. Customizable instantaneous enhanced output is available to meet the customer’s needs to overcome the instantaneous resistance of dirt or ice to the grille.
