Each camshaft is ret ained in t he cylinder head bythe cams haft hous ing. The int ake cams haft is equipped wit h a VCT unit and also drives the vacuum pump.
The intake camshaft has cam lobes wit h different profiles. One for a small lift ing height of 3.6 mm, and 1 for larger lift ing heightof 10.0 mm. The t ransit ion bet ween t he lift ing height s is cont rolled via the Cams haft Profile Swit ching (CPS) funct ion.

Camshaft Profile Sw itching
CPS is a sys tem where t he int ake valves , at engine s peeds up to approximat ely 3000 rpm, have a s mall lifting height of 3.6 mm,and at s peeds above approximat ely 3000 rpm, have a great er lift ing height of 10.0 mm. CPS, in combinat ion wit h t he VCT funct ionmakes it poss ible to cont rol t he cylinders' incoming air quant it y in s uch a way that t he Electronic Throt t le Act uat or (ETA) can befully open. A fully open ETA, during operat ion, reduces t he pump los s es cons iderably compared wit h when the amount of int ake airis controlled by t he ETA its elf. Reduced pump los s es , in turn, cause a reduction in fuel consumpt ion.
The intake camshaft is equipped wit h 3 lobes for each valve. One cent rally locat ed wit h a small lift ing height of 3.6 mm, and 2out er lobes wit h great er (s ame) lifting height s of 10.0 mm.
At small lift ing height s, only t he cent rally locat ed lobe works on t he valve, which occurs via t he inner t appet . The out er lobes workon the outer t appet t hat follows t he movement of t he lobes. The ret urn spring is compres s ed and ens ures that t he tappet isalways in cont act wit h t he camshaft . W hen the cent rally locat ed t appet and t he out er t appet are not joined, t he outer tappetmoves without affect ing the valve. Thus the lifting height is s mall. At high lift ing height, t he inner t appet and t he out er t appet arejoined via t he 2 lock pins .
The pos it ion of the lock pins is cont rolled hydraulically by 2 elect ro-hydraulic CPS solenoid valves . Thes e valves are locat ed in t hecams haft hous ing.

The inner t appet works like a hydraulic t appet , which compens at es for any wear. The valve clearance is t herefore '0'.
The exhaus t cams haft is convent ional and has a lift ing height of 10.0 mm. The t appets are mechanical (i.e. have valve clearance).
