Outline
• The active air shutter system controlled by the PCM reduces turbulent air*1 occurring around the vehicle which reduces air resistance. It does this by closing the active air shutter behind the front bumper mesh while the vehicle is being driven to control the air flowing into the engine compartment. In addition, by closing the shutter and blocking the airflow while the vehicle is driven during cold temperatures, the engine warms up more efficiently. By reducing the air resistance and improving the engine warm-up efficiency, the fuel economy has been improved.
*1 :The air flowing into the engine compartment from the front bumper mesh while the vehicle is driven flows underneath the floor and the tire housings. The air flowing underneath the floor and tire housings collides with the air flowing around the vehicle and creates turbulence.
