Byaba ari igitsina kandi cyiza kuvuga ko hashize imyaka 20, BMW yakoze uburyo bwo guhonyora icyiciro cya GT cya Porsche, ikoresheje ubwenge bwabo gusa na inline-itandatu, ariko sibyo rwose.Moteri ya S54B32 yakinnye gusa icya kabiri kuri 4.0L V8 yamaganwe cyane, ariko iyo ni iyindi nkuru.Ijambo ryukuri ryaba ari uko S54 yamenyesheje iherezo ryumurongo wo gutaka, bisanzwe M50 / S50 umuryango wa BMW inline itandatu.
Byari igishushanyo mbonera kuva mubisanzwe bisanzwe bishyushye: ongeraho bore na stroke kuri moteri ishaje hanyuma wongere tekinoloji nshya iboneka muburyo bwa Double VANOS (BMW vuga kuri kamera ihindagurika ikurikirana kuri kamera zombi zifata hejuru, zishobora guhinduka umurongo wo gufata kuva kuri 70-130 ° hamwe n'umurongo wo hagati uva kuri 83-128 °).Ongeramo akantu gato muri compression (kuri 11.5: 1), imibiri ya trottle kugiti cye, abakurikira urutoki abakurikira rocker cam, abavuzwe haruguru Double VANOS, hamwe nimbere yimbere ibyiciro bibiri byamavuta ya wet-sump, hamwe nibi bintu bitandatu- silinderi ihinduka ikintu kidasanzwe cyane muri 2001 na nubu.
Kugira umusaruro wihariye wa mbaraga zingana na 104 kuri litiro hamwe na stratosfera ya 8000-rpm itukura ntibyari byunvikana hanze yabatariyeri bo hagati yabataliyani bicaye hagati cyangwa abayapani bafite ibiziga bibiri.Ubwiza nyabwo bwiyi moteri buragaragara iyo utanyuye inyamaswa.CNC yerekana umwirondoro wo gufata, ibyumba byo gutwika bya CNC, ibyumba binini binini, ibyuma biyobora umuringa, hamwe n’isukari yuzuye yuzuye ivanze byose bisa nkaho ari murugo kuri moteri yo gusiganwa kuruta ikintu cyavuye kumurongo.
Uru rutonde rwibintu rusoma nkibitekerezo kubantu benshi basanzwe bakora canyon, Ultimate Driving Machine purist.Kubwamahirwe, kuri twe twese, nyuma yinyuma igaburira gukenera abo dukunda kuzamura.Abashoferi, gukurura abasiganwa, nigihe cyo gutera ibitero bishimira ibikoresho binini bya turbo imwe cyangwa centrifugal-blower icyubahiro.Ubwiza nyabwo bwo guhindura moteri nigihembo usarura, mugihe izo nganda zifite imbaraga nyinshi-zikora neza zakira ibyifuzo bidasanzwe hamwe nimpinduka zikwiye zo gushyigikirwa.Iki gice kizakuyobora, imbaraga zidasanzwe, binyuze muburyo bwo gutegura impera yo hejuru kububasha bukomeye mukuzamura.
Mu ntangiriro, tugiye gusenya no kugenzura ibyingenzi byacu.Isima imwe yo kwirinda ni ikiro cyo gukiza hano.Gushyira ubwoko nkubu namafaranga muri casting bidashoboka byaba ari ikosa rikomeye.Mugihe S54 itazwiho gucikamo ibice, gufata umwanya wo gukora isuku, kugenzura neza, no kugerageza igitutu ikoti ryamazi ni imyitozo ikwiye.
Ibyo utazi birashobora kukubabaza hamwe nu gikapo cyawe.Nibyingenzi cyane kugerageza byimazeyo silinderi yawe kugirango urebe neza ko ikwiriye kubona akazi gahenze, gakomeye imbere.
Umaze guhamagara ibyingenzi bifatika, igihe kirageze cyo gusuzuma intego zawe.Iyi nyubako irimo imodoka ya E36-chassis drift, ukoresheje ububiko bwa BMW bugufi-bugufi, byose bigaburirwa na supercharger ya centre ya ruganda.Gukoresha ububiko bugufi-guhagarika bitera akantu gato kuko piston yumwimerere ntabwo yorohewe bihagije kubikorwa bya VVT byuzuye mugihe hari indangagaciro nini zikoreshwa kuruhande.
Kubwiyi nyubako twahisemo ingano ya OEM (35mm) nitride idafite intungamubiri zifata na 31.5mm (1mm zirenze urugero) Inconel yuzuye;byombi muburyo bumwe bwo kurinda groove ihinduka.Byombi binini bya VAC Motorsports bikomoka kuri Schrick "Guhatira Induction" amashusho kandi birashoboka ko rev limiter-gusomana mumasiganwa ya skid bisaba kugenzura neza valve.Ikiramba kirambye cyibice bibiri byo murwego rwo hejuru biva muri Supertech Performance hamwe no guhuza titanium yagumanye.
S54 ikoresha umwihariko-kuri-BMW, ukurikira urutoki ukuboko kwa rocker ukuboko gushizwe kumutwe.Ibi bitanga umuvuduko wo gufungura kwihuta no kugwiza ibipimo bya rocker, ariko, nkuko bamwe babivuga, birashobora kuba ikintu cyo kwambara.Twabonye intsinzi mugukoresha WPC Umuti kubayoboke ba OEM rocker, nubwo bamwe bashobora guhitamo icyuma cya DLC.
Hamwe nibice byashyizwe ahagaragara, ubu dushobora kwegera urutonde rwibikorwa tuzareba mu iduka ryimashini.Nubwo abiruka ba S54 bafata neza CNC-yuzuye, hari uduce duto two kunonosora, nkumwirondoro wintebe na diameter yumufuka-umuhogo.Icyambu gisohoka ni umuvuduko mwinshi, ugabanijwe, D-shusho ya D, igamije gusya ibyuka bisanzwe, RP-yakoresheje gaze.Umwirondoro wakazi, nko kugorora kwiruka, uzagira inyungu hano.Ubusanzwe imashini yububiko bwa valve kugirango iyobore iracyakoreshwa muburyo bwo kohereza ubushyuhe, gufunga valve, no kuramba.Ubuyobozi bwa S54s bugomba gukemurwa nkuko bikenewe.
Nyuma yo gushushanya ibyambu no kwambara, turareba kugirango tworoshe gusa ibyumba byo gutwika ibyumba byerekana ibikoresho.Tugenzura kandi uburinganire bwa volumetric hamwe na burette.Kwitondera cyane ni ukwitondera imyirondoro yintebe, ukurikije ubwiyongere bwa ingano ya valve kumuriro.Intebe ya valve ikora intego ebyiri zingenzi: gucengera ubushyuhe muri valve mukoti yamazi, no gutanga inzibacyuho yo kugaburira icyumba cyo gutwika ikirere cyacu cyifunitse (kandi gikunze guhuzwa).
Intebe yerekana intebe irashobora gukurikiranwa no gukubita intoki kugirango wizere neza ko intebe ihujwe neza.Akazi ka valve kamaze kugenzurwa no kugeragezwa, intambwe ikurikiraho ni ugusya amagorofa no kugenzura flange aho PCD izunguruka ihinduranya “esheshatu na cyenda” kugirango irangire cyane.Igenzura ryanyuma ryabaye muriki gihe mbere yo gukubita ibice byoza.Iyo tumaze kugira ibice bisukuye kandi bikwiye, duhindura intebe-duhindura valve.Twubahirije ibisobanuro byakozwe na kamera hanyuma dusoza inteko yanyuma hamwe nubugenzuzi bwa nyuma.
Mbere yo guca chip imwe, dukeneye gushiraho no gupima intego zacu zose.Ingano yo gufata no gusohora ingano ya 35mm na 31.5mm.Intego yacu yo gufata byibuze 85% kwijana rya 35mm - cyangwa byibura diameter 29,75mm yumuhogo mumufuka hagati yintebe nicyambu.Intego yo gusohora yegereye 90 ku ijana ya 31.5mm - cyangwa 28.35mm - diameter.
Benshi barashobora kubona icyerekezo cyo kwitabwaho kuruha muriyi porogaramu;reka ibi bishimangire akamaro kayo mubikorwa bya volumetric.Wibuke ko ba injeniyeri i Munich bamaranye igihe kinini cyo gufata.Twashize umutwe wa silinderi mumashini yintebe ya Serdi hanyuma dukoresha insimburangingo ya radiyo kugirango tubone diameter yo mu muhogo.Dukeneye iki gipimo mbere yo kohereza abiruka.Iraduha ubushobozi bwo guhuza amaboko ibimenyetso byo gutunganya cyangwa ingendo zasizwe no kuzunguruka mu muhogo.
Gukata intebe yubushakashatsi bifasha gutunganya umufuka wumuhogo.Nubwo ingano yuzuye umuhogo ikiri impaka, nta mpaka zerekana ko kuzamura igipimo cyayo ari ikintu cyingenzi mu kuzamura urujya n'uruza muri rusange.
Icyiciro gikurikira ntigisaba imiterere cyangwa amazi.Ibyambu byo gufata byashyizwe hamwe na O-ring groove kandi umuyaga washobora kuba munini cyane muburyo bwo kwandika no guhuza icyambu.Rero, uburambe nubushishozi nubuhanga bubiri bugabanya guhora-gupfa-gusya.
Ahantu hanini ho gukora chip ni D-igice cya kabiri cyukwezi kwicyambu.Turasya, tugorora, kandi turakabya imiterere D.Ntabwo arenze hafi 2mm yo gukuramo ibikoresho kurukuta rwicyambu bigomba kuba bihagije kubisabwa byinshi bitarenze 1,100 whp.Impande zikarishye hamwe nabatandukanije mukwakira bakira koroshya no kumena ibimasa hamwe na 80-grit ya karitsiye.
Iyo bimaze kumenyekana, umuyaga wakira 80-grit ukurikirwa na 120-grit.Turakurikirana hamwe nurumuri rwambukiranya kugirango dukubite hasi kugirango tugenzure karubone.Icyumba cyo gutwika cyakira kurangiza-gukanda kimwe nu mwuka, gukubita ahantu harehare no gukoresha burr kugirango wirinde ikintu cyose cyabanjirije gutwikwa cyangwa gucana.
Iterambere ryicyambu gisohoka kuva chippy kugera kunyerera.Icyambu gisohoka kibona ibikoresho byinshi byo kuvanaho no kuvugurura kumutwe wa S54 ugenewe kubona imbaraga.
Kwerekana intebe za valve nubundi buryo benshi bafata "ubuhanzi bwijimye."Mubyukuri ntakindi kirenze physics na geometrie.Icyumba cya S54 cyuzuye cya 33cc cyaka ikoresha icyuma cya 12mm cyumucyo gikunze kuboneka muri moto kugirango gihuze na valve yavuzwe haruguru.
Mugukomera hamwe ninsanganyamatsiko yoroheje, yamara ikirere kinini, twahisemo kumyanya 5-inguni na radiyo-yimyanya-myanya, iboneka kubitangwa na Goodson Machine.Imashini zombi zaduhaye imikorere-1mm, intebe ya dogere 45, ihujwe no gukata neza, mu gikombe no hanze.
Niba ukoresha ububiko bwa titanium cyangwa ukoresha urwego rwimbaraga nyinshi cyane, ugomba gutekereza intebe ivanze y'umuringa nka Moldstar90 cyangwa ibisa nayo (witondere kanseri, beryllium alloys).Turangije QC hamwe numurimo wamaboko, dukoresheje ibishaje bishaje, byiza bya clover kugirango tumenye impeta yacu.Itanga kandi neza kumeneka neza mumaso kugirango wirinde guhinduka kwinshi mumashanyarazi.
Izi nzira zirenze gusa izengurutswe kandi zisobanutse neza.Ibi byakemuwe nkibikenewe, mubisanzwe kuva mile-mileage cyane hamwe no gufata neza.Ubuyobozi bukwiye bwo gusimbuza ni umuringa-manganese uboneka muri Supertech Performance.Wibuke, muri ibi bihe, kwibanda ku mwami.
