Variable Intake Solenoid (VIS) Valve
VARIABLE INTAKE SOLENOID (VIS) VALVEINSPECTION
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
