Description

DESCRIPTION





The intake manifold swirl actuator is located between the two intake manifolds.





The intake manifolds have a charge air passage (3) which are oval shaped, and a swirl passage (2) which are round, for each cylinder. The swirl blades (2) are mounted in each intake manifold swirl passage (2) and are not serviceable. The actuator (5) is PWM controlled by the ECM and is constantly adjusting while the engine is running to optimize the air/fuel mixture and create the best possible air turbulence. The result is improved combustion, improved engine performance and a reduction in exhaust particulates. The swirl blades (2) in the intake manifold are held in the open position by an internal spring when not actuated.
