SPLIT INDUCTION

Ford Escort

My daughter has a 1998 Ford Escort SE with 50K miles. The engine is a 2.0 liter. The car was idling a bit rough and was loud when accellerating. Turns out that it had low compression on one cylinder. Changing the head gasket corrected the compression problem and compression is now 185 to 190 lbs across the 4 cylinders. The engine loudness when accellerating is gone and it idles much much better. The engine has what is called 'Split Port Induction'. What is 'Split Port Induction'? There appears to be a motor that drives a shaft that goes throught the intake manifold. I never see this shaft turn but it appears to be free (not stuck). What is this mechanism trying to accomplish and how is it basically controlled? : Roll:
