INSPECTION
FUNCTION AND OPERATION PRINCIPLE
Variable Intake Solenoid (VIS) Valve is installed on the intake manifold and is used to improve intake efficiency.
1. Low/Middle Speed: VIS Valve Close -> Resonation Effect -> Improving Intake Efficiency
2. High Speed: VIS Valve Open -> Improving Intake Inertia Effect -> Improving Intake Efficiency
