Variable Induction System: Description and Operation

View: Variable Inertia Charging System (VICS):

PURPOSE
By varying the length of the intake air path in the intake manifold and dynamic chamber, the resonance induced inertia charging effect is improved, yielding higher torque and a wider torque band.

OPERATION
The length of the intake track is controlled within the intake manifold and dynamic chamber by opening and closing the shutter valve at 4,750 rpm.

CONSTRUCTION
The variable inertia charging system (VICS) consists of the shutter valves, shutter valve actuator, VICS solenoid valve, vacuum chamber, and powertrain control module engine (PCME).
