Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Swirl flap actuator: Notes
The swirl-flap actuator is secured to the intake plenum.
The swirl flaps are continuously adjusted by an electrical swirl-flap actuator. The controllable swirl flaps are located in the swirl ports. Depending on the operating range, the swirl flaps are activated with different duty cycles. The further the swirl flaps are closed, the more fresh air is drawn in exclusively through the swirl port. This increases the swirl of the drawn-in fresh air.
