OVERVIEW
The TD4 engine feat ures a Garret t Rotary Electroni c Actuated (REA) variabl e geomet ry turbocharger. The t urbocharger i smounted t o t he exhaus t manifold on the Ri ght -Hand (RH) s ide of t he engine, and secured t o t he cyl inder block wit h abracket . An oil pi pe wit h banjo type fixing i s att ached bet ween an outl et on the RH s ide of t he cyl inder bl ock and the t opof the turbocharger hous ing, and provides pres s uri zed oi l to the t urbocharger beari ngs. An oi l pipe at tached to the bot tomof the turbocharger is connect ed to the oi l pan hous ing, and direct s ret urn oi l from t he t urbocharger i nt o t he oil pan. Aheat shi el d i s ins tal led over the t urbocharger and exhaust mani fold to protect other component s, and t o prevent acci dent alcont act wit h the hot exhaus t component s .
The t urbocharger compri ses a turbi ne and compres sor wheel mounted on a common s haft, enclos ed wit hin a cas t hous ing.The common s haft i s s upport ed on 2 semi -float ing beari ngs . The cast hous ing forms 2 chambers that clos ely s urround thet urbine and compres s or wheel s. The t urbine wheel i s pos i ti oned bet ween the exhaust gas flow from t he engine and t heexhaus t s ys t em. The compress or wheel is pos it ioned in the i ntake air flow bet ween t he air filt er and out let t o t he chargeair cooler.
Duri ng turbocharger operati on, t he t urbine and compres s or s haft may reach s peeds in exces s of 200,000 rpm, and producea charge ai r (boost ) pres s ure of up t o 1.7 bar (25 ps i). A pre-t urbine press ure of 3 bar (44 ps i) and a temperat ure of 800°C(1472°F) may be generated i nsi de t he turbi ne chamber.
A REA is at tached to the compres s or hous ing, and is connect ed via a li nkage t o a rotary adjus ti ng ri ng located wit hi n t het urbine hous ing. The internal circumference of t he rot ary adjus t ing ring hous es a s et of radial variable vanes . The variablevanes are pos it ioned to int ercept t he exhaus t gas fl ow from the engine, ahead of the t urbi ne wheel .

OVERVIEW
The s tarter mot or is rated at 2.0 kW and is manufact ured by Dens o as a s ealed pi ni on only unit . The s tarter mot or is anRA t ype that i s offset i n desi gn; the s olenoid is l ocat ed direct ly behind t he pini on to provide a more pos it ive engagementwit h t he flywheel ring gear. The mot or is geared direct ly t o t he pinion and is a pre-engaged type compri si ng a s eri eswound mot or and an over-running cl utch.
The mot or i s mounted on the Left-Hand (LH) s ide of t he clut ch hous ing and s ecured with 3 fi xings. The pi nion prot rudest hrough an aperture t o dri ve the fl ywheel via a ri ng gear.
A s mal l di ameter cabl e i s connected bet ween the Engine Cont rol Modul e (ECM) and the s olenoid. The s olenoid i s energizedby a s i gnal volt age from t he ECM when t he s tarter s wit ch is pres sed. W hen engine cranking is reques ted, t he ECM checksfor a recei ved val id mobi li zat ion code before grant ing t he crank reques t.For addit ional informat ion, refer t o: Anti -Theft - Pas s ive (419-01 Anti -Theft - Pas sive, Des cri pti on and Operati on).
Power for s tarter mot or operat ion i s s uppl ied t hrough a l arge di ameter s ingle cable, connected di rectl y t o t he bat t eryposi ti ve terminal . The cable is prot ected wi th a s eal ed 'CAL3' type fus e, located at t he batt ery end of t he cable.For addit ional informat ion, refer t o: Batt ery and Cables (414-01 Bat tery, Mounti ng and Cables , Des cri pti on and Operati on).
The cabl e is secured t o t he s olenoid wi th an anti -rotat ional device and nut.

The batt ery s t atus i nformat ion is t rans mit t ed from t he BMS modul e over t he LIN (l ocal i nt erconnect network) bus t o t heCJB which has a t wo-way communi cat ion wit h the BMS module. The cont rol l ogi c for i nhi bi ti ng engine s hutdown andini ti at ing an early engi ne res tart during a Start/Stop cycl e resi des in t he CJB. The CJB al so act s as t he gateway relayingt hi s informat ion t o t he ECM over the hi gh-s peed CAN bus.

The BMS module cons tant ly computes t he s t at us of the el ect ri cal s ys tem on the bas is of the followi ng data:

If any of t hese factors s how a l ow meas urement, t he ECM s us pends t he Stop/Start feature unti l more bat tery power i savai lable. The fact ors are dis cus s ed below:

This degradat ionwil l reflect on the amount of charge t he bat t ery can hold unt il it reduces t o a condit ion where the bat tery wi ll needrepl acing.
The batt ery moni toring s yst em cal culat es t he condit ion of t he batt ery by obs erving a range of i nput s including:

Stat e of charge
The BMS analys es how much charge has been drawn or repl enis hed to det ermi ne t he bat tery’s pres ent s tat e of charge.

The batt ery wi ll dis charge more rapi dly due t o t he high current demand.
In thi s event t he BMS calculat es various fact ors t o determine how long t he batt ery can s upply a current at the presentlevel of demand. This calculat ion i s used by the CJB t o determine if t o authori ze whichever i s needed i n t he Stop/St artcycle, ei ther to:

Batt ery replacement
If a new batt ery is fit ted t o t he vehicle, the BMS (bat tery monit ori ng s ys t em) module wi ll requi re recal ibrat ing t o regi s tert he greater charge holding capaci ty of the bat tery, t his i s performed us ing Land Rover approved di agnos ti c equi pment. If adiagnost ic s ys tem is not avail abl e t he BMS module will recal ibrat e automat icall y however, this could take 48 hours tocomplete depending on vehicle usage.
