LESSON 3: POWERTRAIN

Charge Motion Control Valves (CMCV)

The Charge Motion Control Valves (CMCV) are electronically controlled metal flaps at the end of each intake

runner, eight in total (four per bank on one rod, operated together).

•

CMCVs work to speed up the intake air charge and induce a ‘‘tumble’’ effect into the combustion chamber at

low engine speeds and loads.

– Causes a thorough mix of the air/fuel charge.

– Results in a quick, efficient burn which helps reduce emissions.

– Close at low engine speeds and light loads.

– Helps manage noise, vibration and harshness.
