Which kind of variable cam the MIVEC is?
Does it use different cams with different profiles on the same shaft, or variable profile cams, or does it varies the phase of the camshaft, or what else?

 

Search is your friend. Edit* But not in this case. Damn hard to find good information sometimes

It is basically a hydraulically actuated cam gear.

 

A little more information

"The Lancer Evolution's MIVEC system uses the engine's oil pressure to engage movement of the intake camshaft's front sprocket. As the camshaft control signals are received from the ECM, a spool valve at the oil control valve moves the sprocket toward the advance or retard side depending on the ECM signal. As the intake camshaft's actual and target sprocket angles meet, the oil pressure in the advance and the retard chambers is held to maintain the phase angle of the camshaft. The MIVEC system's oil control valve is a closed loop system so that the actual and target phase angels are identical"

Hehehe! You noticed it too, eh?
Thanks for the answer.
So, ity's basically the most basic and traditional kind of variable cam: the "varable phase camshaft".

 

Yup. It's the same as the "i" in iVtec.
