Kodi mungatani kuti musakonde chilimwe? Inde, kumatentha, koma kumapitirira kuzizira ndipo mumafunikira nthawi yambiri. Ku Engine Builder, gulu lathu linali lotanganidwa kupita ku zochitika za mpikisano, ziwonetsero, kupita ku opanga injini ndi masitolo, komanso ntchito yathu yanthawi zonse yokhudza zinthu.
Ngati palibe pini yopezera malo mu chivundikiro cha nthawi kapena chosungira nthawi, kapena ngati dzenje la pini yopezera malo silikugwirizana bwino ndi pini, tengani chopondera chakale ndikuchipukuta pakati kuti chizitha kutsetsereka pamwamba pa mphuno ya crank. Gwiritsani ntchito kulimbitsa chivundikirocho pomangirira mabotolo.
Kaya ndinu katswiri wopanga injini, makanika kapena wopanga, kapena wokonda magalimoto amene amakonda mainjini, magalimoto othamanga ndi magalimoto othamanga, Engine Builder ali ndi china chake kwa inu. Magazini athu osindikizidwa amapereka tsatanetsatane waukadaulo pa chilichonse chomwe muyenera kudziwa chokhudza makampani opanga injini ndi misika yake yosiyanasiyana, pomwe njira zathu zamakalata zimakusungani kuti mudziwe nkhani ndi zinthu zaposachedwa, zambiri zaukadaulo ndi zamkati mwa makampani. Komabe, mutha kupeza zonsezi pokhapokha polembetsa. Lembetsani tsopano kuti mulandire magazini yosindikizidwa ndi/kapena yamagetsi ya Engine Builders Magazine pamwezi, komanso Weekly Engine Builders Newsletter yathu, Weekly Engine Newsletter kapena Weekly Diesel Newsletter, molunjika ku inbox yanu.

Si chinsinsi kuti pakakhala mphamvu zambiri zoyaka, ndikofunikira kwambiri kuti mutu wa silinda ukhale wokhazikika pamwamba pa silinda. Chifukwa chake ndikofunikiranso kusankha mtundu wa zovala zamutu zomwe mumadalira kuti zigwire ntchitoyo.
Kaya muli ndi galimoto yogwirira ntchito yomwe imagwira ntchito tsiku lonse, galimoto yopangidwira ntchito zosiyanasiyana, kapena china chake pakati pa izi, palibe kukayika kuti magalimoto onse adzapindula ndi ma bolt atsopano a masilinda.
Ponena za kugula zomangira injini monga ma stud, zakhala zikutsogola pamndandanda - ARP. ARP yakhalapo kwa zaka zoposa 50 ndipo, chifukwa cha ulemu wake, ikupitilizabe kuyesetsa kupanga zomangira zapamwamba kwambiri kuti zigwiritsidwe ntchito molimbika. Komabe, mpikisano m'derali wakhala ukuwonjezeka posachedwapa ndipo imodzi mwa makampani omwe akupikisana pamsika ndi Gator Fasteners, kampani ya KT Performance yochokera ku Groveland, Florida.
Si chinsinsi kuti pakakhala kutenthedwa kwambiri, ndikofunikira kwambiri kuti mutu wa silinda ukhale wokhazikika pamwamba pa silinda. Chifukwa chake ndikofunikiranso kusankha mtundu wa zovala zamutu zomwe mumadalira kuti ntchitoyo ithe. Posachedwapa tidalankhula ndi ARP za zinthu zawo za stud yamutu komanso tidalankhulanso ndi Zeigler Diesel Performance ku Canton, Ohio za zomangira za Gator kuti tidziwe zatsopano pa stud ndi ukadaulo wa kampani iliyonse, komanso kufanana ndi kusiyana komwe kulipo pakati pa anthu omwe amagwiritsa ntchito dizilo.
Kawirikawiri, chomangira fakitale masiku ano chimakhala chomangira mphamvu ya yield. Izi zikutanthauza kuti pakapita nthawi pali mwayi waukulu woti muchotse mutu wa silinda pa block ndikuwononga gasket ya mutu wa silinda. Ma bolts a Aftermarket ochokera ku ARP kapena Gator Fasteners satambasuka ngati ma bolts a fakitale chifukwa alibe mphamvu ya torque yield.
"Ponena za magwiridwe antchito a dizilo, nthawi zambiri timaposa zida za fakitale ndi 20 peresenti," adatero Chris Raschke wa ARP. "Imeneyo ndiyo inali cholinga chathu. Tinkafunanso chinthu chomwe chingagwiritsidwenso ntchito. Anthu ambiri omwe tidalankhula nawo adagwiritsa ntchito misomali ya ARP2000 ndi 625."
ARP imapereka zida zomangira mutu zamainjini osiyanasiyana a gasi ndi dizilo, ndipo zomangira za Gator zimagwiriranso ntchito mapulatifomu akuluakulu a injini ya dizilo. Komabe, Gator sizikuwoneka kuti ili mbali ya gasi pamsika, koma imabwera ndi njira ya LS head bolt.
Pa injini za dizilo, ma bolt a Gator amapangidwira injini za Duramax za 2001 mpaka injini ya L5P yatsopano ya 2020. Ma injini a Powerstroke ndi Cummins amayambira pa Rams mu 1989 mpaka Powerstroke mu 1994 mpaka chaka chino.
“Zomangira za Gator zikuwoneka bwino kwambiri poyerekeza ndi zomwe ndawonapo,” anatero Justin Zeigler wa Zeigler Diesel Performance. “Ndaona ma stud ena okayikitsa kwambiri ochokera kwa opanga ena. ARP yakhala ikuwagwiritsa ntchito kwa nthawi yayitali kuposa wina aliyense. Komabe, ndikuganiza kuti zomangira za Gator ndi chisankho chabwino komanso chisankho chabwino. Ndimakonda mtundu, mtengo ndi kupezeka kwake. 'saw.'
Ndi mphamvu yokoka yoposa 220,000 psi, zomangira za Gator sizitambasuka ngati mabotolo a fakitale. Zimapangidwa ndi ulusi wopindika pambuyo potenthedwa kuti zikhale zolimba kwambiri. Ndi zopanda pakati kuti zikhale zolimba ndipo zida zonse zimakhala ndi chitsulo cha chrome chotenthedwa ndi kutentha, mtedza wa 12 point womwe umaphwanyidwa ndi ma washer okhala ndi utoto wakuda wa oxide kuti ukhale wolimba.
Ngakhale kuti Gator monga kampani yatsopano ingapereke zinthu zapamwamba mwachibadwa, ikusowabe chimodzi mwa zinthu zabwino kwambiri komanso zazikulu zomwe ARP imapereka - zomwe imachita.
“Timagwiritsa ntchito chotenthetsera mphamvu kuti tiwone zomangira za fakitale ndi njira yomangira fakitale kuti tiwone momwe zimagwirira ntchito zomwe mumapeza kuchokera ku zomangira za fakitale,” Raschke akufotokoza. “Ndicho chomwe tidapanga kuchokera pamenepo. Tilinso ndi chotenthetsera kutentha, chomwe ndi ng'anjo yokhala ndi chipinda choyesera mkati, ndipo mutha kutentha chilichonse mpaka kutentha kwa injini kuti muwone momwe zimakhudzira zomangira pa kutentha kwa ntchito. Tikapanga zida zomangira za ntchito iliyonse, tiyenera kuganizira izi. Tili ndi zida zambiri m'bokosi lathu la zida kuti tichite zomwe tikufuna.”
Kale, zomangira zidagwiritsa ntchito zipangizo 8740 pa 180,000-200,000 psi, zomwe nthawi zonse zakhala zokwanira kusintha zida za fakitale. Masiku ano, makampani monga ARP amapatsa makasitomala mwayi wosankha ARP2000, Inconel kapena Custom Age 625 PLUS yokhala ndi mphamvu yolimba kwambiri.
“Ndi zinthu 8740, mutha kugwiritsa ntchito psi pafupifupi 200,000 zokha, zomwe ndi pafupifupi 38-42 pa sikelo ya Rockwell, ndipo pamenepo ndi pomwe chisangalalo chimayambira,” anatero Raschke. “Ngati muyesa kukweza pamwamba, mudzatopa ma headpins. Muyenera kusankha zinthu zomwe zimagwira ntchito pomwe ziyenera kugwirira ntchito.”
ARP 2000 idachita bwino kwambiri pa 220,000 psi ndipo, malinga ndi Raschke, idakali ndi mphamvu zabwino zotopetsa komanso kusinthasintha kwabwino pamakina opondereza kwambiri. Kuchokera pamenepo, ARP imapereka zida zake zakale zomwe zimapangidwira.
“Chimodzi mwazinthu zabwino kwambiri za Custom Age ndikuti ndi chitsulo chosapanga dzimbiri chomwe sichingapange dzimbiri,” adatero Raschke. “Ili ndi mphamvu yolimba kwambiri (260,000+ psi) kotero mutha kuyigwedeza ndikusangalalabe. Ndi chitsulo chosapanga dzimbiri, vuto la ma dizilo ndilakuti ali ndi kutentha kwambiri, chinyezi, utsi - ndizo zonse “Sizili chimodzimodzi ndi zida wamba zachitsulo. Dzimbiri limatulutsa haidrojeni, ndipo kuphulika kwa haidrojeni kumatha kuwononga zomangira. Ngati mutentha kwambiri ma stud kuti akhale olimba, mudzakhala ndi dzimbiri chifukwa cha dzimbiri. Mwayi wa mavuto a kuphulika kwa haidrojeni ukuwonjezeka kawiri.”
Zachidziwikire, sikuti zinthuzo zokha zimakhudza mkombero womwe ukugwirizana ndi zosowa zanu, komanso kukula kwake. Nthawi zambiri, mabolt a mutu wa 12mm angagwiritsidwe ntchito pazinthu zambiri za Cummins. Komabe, anthu ena ogwira ntchito bwino kwambiri angagwiritse ntchito ma stud a 14mm, ma stud a 9/16, kapena ma stud a 5/8.
“Nthawi zambiri, ma Cummins anu onse a fakitale adzakhala ndi ma stud a 12mm,” anatero Ziegler. “Mu dziko la mpikisano, nthawi zonse takhala tikugwiritsa ntchito 14mm kapena 9/16 kuti tipeze mphamvu yowonjezereka. Ma bolt a mutu pa galimoto yanga yothamanga amakokedwa kufika pa 250 ft.lbs. Ma 12mm amenewo ndi 125 ft.lbs. Kusiyana kwakukulu pakugwirira, komanso ndi kosiyana kwambiri.”
Raschke anati anthu ambiri ku Cummins anayamba kuboola ma stud akuluakulu chifukwa chakuti analibe zipangizo zokwanira zolimba za ma stud m'mbuyomu. Tsopano, chifukwa cha ARP, achita izi.
“Ngakhale anthu akufunabe kugwira ntchito ndi mabuloko, timawapatsa zipangizo zapamwamba,” iye anatero. “Nthawi zambiri njira yathu yothetsera vutoli ndi kupanga zomangira zapamwamba kwambiri kuti zigwiritsidwe ntchito m’fakitale. Ngati mukufuna kusintha zinazake, dipatimenti yathu yapadera imakwiya kwambiri. Tagwira ntchito pa magalimoto osiyanasiyana a dizilo. Opanga amachita izi, mwachitsanzo, Shade, Heisley, Wagler ndi ena”.
Ngakhale nthawi zina kukula kwakukulu kumamveka bwino, Raschke ali ndi machenjezo kutengera chipika chanu, mutu wanu, ndi zomwe muyenera kuchita kuti mugwiritse ntchito bwino chiphuphu chachikulucho.
“Ndi malo opanda kanthu awa, anthu ena amagwiritsa ntchito 9/16 kapena 5/8,” iye anatero. “Pomaliza, mutha kuyikapo stud yayikulu kwambiri, koma khoma la silinda silingathe kulichirikiza, kapena palibe malo oyikapo gasket ya mutu wa silinda, ndipo mudzawononga chipikacho. mutu suli wolimba mokwanira kuti ugwire ma clamp apamwamba Katundu wolemera? Pali zinthu zambiri zoti muganizire m'malo mongoyika china cholimba. Muyeneranso kukhala ndi chotsukira mutu chokhala ndi mawonekedwe ake kuti mugwire izi.
"Pa gasket yokhala ndi zigawo zambiri yomwe ikugulitsidwa masiku ano, muyenera kukhala ndi zomangira zomwe zimakhala bwino kwambiri pagalimoto yamsewu kuposa pagalimoto yampikisano, chifukwa ndi galimoto yampikisano mumatha kuichotsa ndikuikonza pafupipafupi, pomwe galimoto yamsewu imafunika kuyendetsedwa makilomita masauzande ambiri. Simungathe kupukuta mutu, ndipo simungathe kuikulitsa ndikuyifinya."
Zeigler anayankha ndemanga izi ponena kuti nthawi zambiri sipafunika ma stud akuluakulu kapena zipangizo zolemera.
“Ngati ndi pulogalamu yodzichepetsa yomwe ilibe chilichonse chachilendo, ndiye kuti palibe chifukwa chowonongera ndalama zambiri chonchi,” anatero Ziegler. “Ngati ntchitoyo yachitika bwino, mabolt abwino okhala ndi makina ochapira zovala abwino komanso kukonzekera bwino sikudzakhala vuto.”
Monga momwe zimakhalira ndi ntchito zambiri za injini, kuchita bwino ntchitoyo ndi 99% kopambana. Izi zikugwiranso ntchito pomanga boluti ya mutu. Tinakumana ndi Justin ku Zeigler Diesel Performance kuti tiwonere Gator Fastener ikuyika maboluti a mutu a 12mm pa injini ya Cummins 24 valve.
Nthawi yomweyo, Justin anayamikira Gator chifukwa cha kulongedza kwake ndi momwe amaonekera. Ma stud a Gator ndi ARP amabwera m'bokosi lofanana, lomwe limaphatikizapo zida zofunika, zilembo zodziwika bwino, ndi malangizo oyika. Ma stud a ARP nthawi zambiri amapakidwa m'mabokosi apulasitiki osiyanasiyana, mtedza ndi ma washer m'matumba apulasitiki. Ndi ma clasp a Gator, ma stud amaikidwa m'bokosi lokongola la pulasitiki, stud iliyonse imakhala ndi chivundikiro cha pulasitiki choteteza ulusi, ndipo ma washer ndi mtedza amabwera m'matumba osiyanasiyana. Kusiyana kwakukulu ndi mafuta omwe amaperekedwa. ARP imapereka phukusi laling'ono la mafuta ndipo Gator imapereka chubu chachikulu cha mafuta oyika AMSOIL.
Musanayike zipilala zilizonse komanso mutatsegula pompo m'bowo lililonse, ukhondo ndi wofunikira kwambiri kuti mupewe mavuto mtsogolo.
"Chofunika kwambiri ndikuyang'ana kwambiri pa ukhondo," adatero Ziegler. "Mukaboola mabowo, muyenera kuwatulutsa ndi mpweya ndikupukuta chilichonse ndi chotsukira mabuleki kuti muwonetsetse kuti chilichonse chomwe tili nacho chili choyera kwambiri tisanayike ma pad pamwamba."
Chida cha Cummins Gator stud chimabwera ndi ma stud 26 - ma stud 6 ataliatali kunja kwa mutu ndi ma stud 20 afupiafupi mkati. Chida chilichonse chimadzozedwa ndi mafuta omangira musanachiyike pamutu ndi pa block. Mofanana ndi ma stud a ARP2000, ma alligator awa a 12mm amafunika ma torque atatu kuti afike pa 125 ft-lbs. (40, 80 ndi 125). Kumbali inayi, ma stud a ARP 625 amafika pa 150 ft-lbs. (50, 100, 150). Malangizo a mitundu yonseyi amafotokoza mosavuta momwe mungapangire stud pamalo ake.
Monga tanenera, ARP yapanga zomangira zonse, kotero tikukulimbikitsani kuziyika pokhapokha ngati muli ndi 80% ya katundu, ngati mukufuna kuti zikhale zolimba kuti zikule, pali 20% ya zomangira. Gator kapena ARP sangakuuzeni ngati zomangira zawo zingagwiritsidwenso ntchito. Justin angakuuzeni nokha zomwe mungathe.
“Zaka zingapo zapitazo, thirakitala yanga inali ndi ma ARP stud omwewo a injini zisanu zosiyanasiyana,” iye anatero. “Ndinawayeza koma palibe chomwe chinatambasuka kapena kusintha, kotero ndimawagwiritsa ntchito nthawi zonse ndipo sindinakhalepo ndi vuto.”
Kukhazikitsa stud kungatenge maola 4-6 kutengera ntchito. Ngati mulibe malo anu ogwirira ntchito, chinthu chokhacho chomwe simungachiyerekezere ndi kutumiza mutu kuti umalizidwe.
Mwachidule, ma hairpins si okwera kwambiri, komanso si kuwakhazikitsa, koma mukufunabe kuonetsetsa kuti mukugwira ntchitoyo bwino, chifukwa zotsatira zake zochita molakwika zingakhale zoopsa.
“Chinthu chachikulu ndi kusankha kuphatikiza kotsimikizika,” akulangiza Raschke. “Anthu amapita pa intaneti ndikusankha turbocharger iyi, injector iyi, mutu uwu ndi mphete iyi yamoto, ndipo amasakaniza zonsezi pamodzi koma sizikugwirabe ntchito. Amagwiritsa ntchito malingaliro a anthu anayi kapena asanu osiyanasiyana m'malo mosankha kuphatikiza komwe kukugwirizana ndi zosowa zawo. Mukamapanga chilichonse, nthawi zonse muyenera kuyang'ana chithunzi chachikulu.
"Muyenera kukhala ndi makina ochapira oyenera, makina ochapira oyenera, ndi makina ochapira mutu. Mukachita bwino kwambiri, mumalowa mu firerings ndi zina zotero."
Malinga ndi Zeigler, si anthu ambiri omwe amalakwitsa pankhani ya mikwingwirima yokha, koma m'malo mwake amalakwitsa kukonzekera kwake.
"Kuonetsetsa kuti malo oimikapo mipando ndi oyera n'kofunika kwambiri, makamaka mukamagwiritsa ntchito makina ochapira zitsulo opangidwa ndi laminated - malo oimikapo mipando ayenera kukhala abwino," adatero Zeigler. "Mukufuna kuti malo oimikapo mipando akhale ofanana nthawi zonse."
Masiku ano, pafupifupi gawo lililonse la injini limapatsa ogula njira zosiyanasiyana. Komabe, zida za injini zitha kukhala chimodzi mwa madera ochepa omwe ARP ndiyo mtundu wosankhidwa bwino kutengera mtundu, luso, ndi malonda. Kulamulira kumeneko sikukudziwikabe, koma osewera ambiri akulowa pamsika, monga Gator Fasteners, ndipo mavuto aposachedwa a unyolo wogulitsa akupatsa ena mwayi.
“Palibe amene angakhudze kupambana kwa ARP,” akuvomereza Ziegler. “Komabe, ndikuganiza kuti Gator Fasteners ikhoza kukhala yopambana ngati siigwira ntchito mopitirira muyeso pamtengo. Mtengo wake ndi wabwino ndipo khalidwe lake ndi loyenera. Ndikuganiza kuti ingakhale njira yabwino kwambiri, osati zinthu zina kuposa ARP, chifukwa tsopano tikudikira kwa miyezi ingapo.”
Raschke adavomereza kuti ARP ikukumana ndi mavuto chifukwa opanga ambiri akuvutika kukwaniritsa zomwe akufuna. Kampaniyo ikuyesetsa kuchepetsa nthawi yodikira ndikuwonjezera kuchuluka kwa ntchito, adatero.
"N'zovuta kupambana zomwe ARP imakupatsani, koma Gator Fasteners imawoneka ngati chisankho chofanana."
