Description And Operation: Description
WARNING: This page is about a different variant/trim than selected.
Variable charge motion actuator reinforces the tumble of the air that flows inside the cylinder, improves combustion performance, and enhances engine torque and fuel efficiency in low to mid speed range. ECM drives ON/OFF the motor to control the VCMA.
VCMA is usually "Closed" and creates tumble for the air intake when vehicle is started. When vehicle accelerates and reaches approx. 2, 600 RPM, actuator operates VCM flap (Open) and facilitates the flow of air intake.
