The ONLY reason vct was used is for emission.Changing the cam event on the exhaut allows some residual exhaust gas to remain in the cylinders(egr !!!),the complex hub used on the cam drive takes the form of an oil fed 'sprag' clutch to kick the timing point back.Its operated by engine oil pressure via a solinoid.Was being developed in 1991 on the proto 'Zeta' (the engine prog WAS Zeta then, not Zetec)...as a 'cost save' on the egr valve,pipes and plumbing.....
