ACTUATOR-INTAKE PORT SWIRL
DESCRIPTION
The intake manifold swirl actuator is located between
the two intake manifolds.
The intake manifolds have a charge air passage (3)
which are ovate, and 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 con-
trolled 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 perfor-
mance and a reduction in exhaust particulates. The
swirl blades (2) in the intake manifold are held in the
open position by an internal spring in an un-powered
state.
