CAUTION: To mai ntain the correct operat ion of t he St op/Start sys t em care must be taken when repl acingcomponents , t hat onl y approved parts are fit ted as some components from earl ier vehicl es wil l fi t the TD4_e.
Starter Motor
To i mprove durabil it y due t o the increased st art -demands on t he s tarter mot or a number of i mprovements have beenmade:
Greas e s eals have been upgraded.A hard weari ng copper-tungs ten contact mat erial has been int roduced t o i mprove wear res i st ance wit hi n t he s tarters olenoi d.The pinion gear i s manufactured from a harder grade of st eel.
Flywheel Ring G ear
Due t o t he increas ed s tart -demands , the flywheel ri ng gear i s manufactured from a harder grade of st eel wit h 25% morecarbon cont ent which increas es it s durabil it y.
Dual Mass Flywheel
As wi th previ ous dies el powered vehicl es a dual -mass flywheel is fit ted to ens ure refi nement when the engine i s beingeit her s t art ed, s t opped or runni ng at low speeds.
To provide an even greater level of refi nement due t o t he i ncreas ed s tart and s top demands , a new fri ct ion di sc has beendevel oped for the TD4_e dual-mas s fl ywheel . The new frict ion dis c whi ch is able to wit hst and s even-t imes the press ure ofa s t andard dis c is manufact ured from polyetheret herketone als o known as PEEK.
PEEK is a s emi-cryst all ine t hermoplas ti c, whi ch is res is tant t o both organi c and aqueous environment s . It has ahigh-melt ing point making it res i st ant to thermal degradati on. It i s als o one of t he few pl ast ics compati ble wi th ult ra-hi ghvacuum appl icat ions and i s t ypi cal ly us ed in bearings , pi s ton part s and pumps .

Convent ional bat teries los e t heir capacit y t o hold charge overt ime as t hei r int ernal l ead plat es st eadi ly det eri orate wit ht he cont inual vi brati on and eros ion t hat occurs wit h normal us e. The rate of det eri orati on depends on a number of fact ors ,including charge and di s charge cycling rat es . Therefore t he ext reme power cons umpti on of a Stop/St art s ys tem would havea det riment al effect on t he li fe-s pan of t his t ype of bat t ery.
To count eract the deeper dis charge and recharge cycl es of a Stop/St art s ys tem, a hi gh-performance batt ery bas ed onAbsorpti on Glas s Mat t echnology has been developed t o reduce batt ery det eri orati on caus ed by exces s ive us age. Thebatt ery owes i ts succes s t o t he ‘abs orbent glas s mat’ whi ch is a fi ne fi breglas s mat compres sed bet ween t he lead plat es.The ‘abs orbent gl ass mat’ als o abs orbs t he batt ery acid, enabling a more efficient us e of the cell ’s volume.
W hi le t he ‘abs orbent glas s mat ’ permit s t he electrol yte to funct ion normall y, i t also provides mechanical s upport for t helead pl at es , therefore reducing vi brat ion and s ubsequent degradat ion. Thi s t echnology s ubs t ant ial ly i ncreas es t he effect ivecharge and dis charge li fe of t he batt ery. The batt ery al s o has an extremely l ow int ernal res is t ance, res ult ing i n a quickerreacti on between acid and pl ate material.
Absorpti on glas s mat batt ery t echnology offers s everal advant ages :
The batt ery remains complet ely s pil l and leak proof due to the abs orpt ion of t he fi breglas s mat .In freezi ng condit ions , expanding flui d is unable to caus e any damage as the pl ates are packed i n fibreglas s mat s ;cons equent ly t here is virtual ly no pl at e movement .Vibrat ion or s hock does not damage t he batt ery.As electrolyt e is contai ned through t he acid i n t he mat , there is no need for bat t ery mai nt enance.
The batt ery's capaci ty is 80Ah, meani ng t he bat t ery i s theoret icall y capable of s upplying an 80 amp current for one hour. At ypi cal engi ne res t art wi ll draw a very hi gh current for a fract ion of a second, s o wi ll have very l it tl e impact on t he batt ery'st ot al st ate of charge. An engine res tart may typicall y cons ume about 0.001% of a new batt ery's full -charge capaci ty.
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. Ifdiagnost ic equipment i s not avail able t he BMS modul e wil l recalibrate aut omati cal ly however, thi s coul d t ake 48 hours t ocomplete depending on vehicle usage. The Stop/St art s ys tem wil l not funct ion correctly unt il t he BMS module isrecali brated.
