• NOTE: Freelander 2 feat ures a new TD4 dies el engine. This TD4 di esel engine i s not previousl y us ed by Land Rover, andmus t not be mis t aken for the Td4 di esel engine us ed wi th t he previ ous Freel ander model.
The new TD4 di es el engi ne may al so be referred to, and appear i n t ext as t he 2.2L Duratorq-TDCi (DW ) engi ne.
The TD4 dies el engi ne is a 2.2 l it er in-line 4 cyl inder as s embly, compri si ng a Double O verhead Cams haft (DOHC)arrangement t hat operat es 4 valves per cyl inder. The valves are operat ed by roller-type fi nger rockers and hydraul ic l as hadjus ters. Ai r and dies el fuel are deli vered to the cyli nders wit h an el ect ronic cont roll ed Vari abl e Geometry Turbine (VGT)t urbocharger, and Bos ch Generati on 3 common rail fuel s ys tem.
Engi ne operati on is monit ored, and opt imum performance is achieved wi th an electronic engi ne management s ys tem andBosch Engine Cont rol Module (ECM).
The engi ne is a compact unit t hat occupies mi nimal s pace, and is des igned t o reduce produced levels of Nois e, Vibrat ionand Hars hness (NVH). The reduced engine si ze allows the vehicle to achieve high level s of pedes t ri an protect ion, and meett he st andards for hi gh-s peed cras h performance.
Engi ne cons t ructi on is formed wit h a preci s ion machined, cas t-alumi num all oy cyl inder head and a lami nat ed met al gas ket,

The cyl inder head and st ructural cams haft cover are manufactured to form mat ing parts . The part s are mil led i n a si ngl eoperati on and accurat ely pos it ioned wi th 2 alignment s leeves. The 2 components mus t al ways be ins tall ed t oget her, andnot renewed as s eparate component s . The cyl inder head and cams haft cover are s eal ed to each ot her during manufact urewit h a gas ket and s ili cone bas ed s eal ant, and are s ecured wit h 27 bolt s . An oil s eal i nst all ed at the front of t he cyl inderhead provides s eal ing of t he exhaus t camshaft hous ing. The open port s at the rear of the cyli nder head are sealed wit ht he vacuum pump and hi gh-pres s ure fuel pump s eal ing rings .
Two ali gnment sl eeves correct ly l ocat e t he cyl inder head and gas ket to t he cylinder block. The cyli nder head is secured t ot he cyl inder bl ock wit h 10 deep-s eat ed bolt s .
• NOTE: The cyl inder head bol ts are not acces si ble wit h the st ruct ural cams haft cover i nst all ed.
• NOTE: The cyl inder head is not t o be reworked.
The cyl inder head is manufact ured from al uminum alloy, havi ng valve s eats and guides made of s i nt ered st eel. Thecyl inder head is precis ely machi ned and mil led t o i ncorporate t he 4 combus ti on chambers, cams haft l ower beari nghous i ngs , oil drill ings and cool ant gal leri es, and t he air i ntake, val ve ti ming and fuel sys t em component bores andhous i ngs .
The desi gn of the cyli nder head maximizes air flow and s wi rl i n the combus ti on chambers. The 2 int ake val ve seat s aremachined wit h rais ed profil es that act to promote swi rl of t he int ake ai r fl ow. Combined wit h t he acti on of the i ntakemanifold heli cal port , t he s wirl effect of the 2 int ake port profi les al lows t he air and i nject ed fuel t o complet el y mi x, andreach t he outer edge of the combus ti on chamber.
The s truct ural camshaft cover is manufact ured from alumi num all oy, and i s machined on t he upper s urface wit h t hecamshaft upper bearing hous ings .
