Intake Manifold Runner Control Systems (2018)

The Intake Manifold Runner Control (Charge Motion Control Valve) that has been used on vehicle programs with the 5.0L and 5.2L engines (Mustang and F150) since 2015 MY consists of a manifold mounted vacuum actuator and a PCM controlled electric solenoid. The linkage from the actuator attaches to the manifold butterfly plate lever for each bank. The IMRC actuator and manifold are composite/plastic with a single intake air passage for each cylinder. The passage has a butterfly valve plate that blocks most of the opening when actuated, leaving the top of the passage unblocked to generate turbulence. Vacuum holds the butterfly valve plates closed, the return spring opens the butterfly valve plates when vacuum is released. There is a monitor circuit for each bank to provide feedback to the PCM indicating butterfly valve plate position.

Below approximately 3000 rpm, the vacuum solenoid will be energized. This will allow manifold vacuum to be applied and the butterfly valve plates to remain closed. Above approximately 3000 rpm, the vacuum solenoid will be de-energized. This will allow vacuum to vent from the actuator and the butterfly valve plates to open.
