GM LS injini: zvese zvaunoda kuziva

LS nyika!

Kutsiva ngano yemhando ipi zvayo ibasa rakaoma. Asi kana zvasvika kune Chevrolet yakakurumbira diki-block V8 injini (yakatanga kubva 1954 kusvika 2003 muGen 1 uye Gen 2 mafomu, ichigonesa zvese kubva kuCorvettes kuenda kumarori ekutakura), chero mhuri yeinjini iri kuedza kuitsiva ine mabhutsu mahombe. . .

Ehe, tarisiro yehunyanzvi uye kubuda kwemhepo hazvisi zvemubvunzo, uye pakupedzisira, Chevrolet yaida kutsiva yepakutanga diki block yakagadzirisa matambudziko iwayo. Mhedzisiro yacho yaive mhuri yeinjini yeLS.

Kugadzirwa kweiyo diki block uye LS renji kwakanyatso kupindirana kwemakore akati wandei (kunyanya muUS), uye yekutanga LS musiyano wakaonekwa muna 1997.

Iyi tag, inozivikanwawo seGen 3 injini, yakagadzirwa kusiyanisa V8 itsva kubva pakugadzirwa kwekutanga Gen 1 uye Gen 2 zvidhinha zvidiki.

Iyo LS V8 modular injini mhuri inowanikwa mune ese aruminiyamu uye yakakandwa simbi crankcase maumbirwo, kwakasiyana-siyana kutamiswa, uye mune ese ari maviri echisikigo aspirated uye supercharged masisitimu.

Kufanana neyekutanga Chevy V8 diki-block injini, injini yeLS inoshandiswa mumamiriyoni emotokari kubva kune akasiyana maGM brand, anosanganisira mota nemagetsi ekutengesa mota.

MuAustralia, isu takaganhurirwa (mupfungwa yefekitori) kune LS alloy vhezheni muHolden branded zvigadzirwa, HSV mota, uye yazvino Chevrolet Camaro.

Kwenguva pfupi, HSV yakashandura Camaros kuita dhiraivha yekurudyi.

Munzira, maAustralian Holdens akaiswa kekutanga kudzokororwa kwe1-litre LS5.7, kutanga ne2 VT Series 1999, iyo yaidada 220kW ne446Nm yetorque ine simba re4400rpm.

VX Commodore iri muV8 fomu yakashandisawo LS1, ine simba rekuwedzera kusvika pa225kW ne460Nm. Holden yakaramba ichishandisa injini imwe chete yemhando dzayo dzeSS neV8 apo Commodore yaichinja modhi yeVY neVZ, ine simba rinokwanisa 250kW ne470Nm.

2004 Holden VZ Commodore SS.

Iyo ichangoburwa yeVZ Commodores yakafumurawo L76 vhezheni yeinjini yeLS, iyo yaive nekutamiswa kwemarita 6.0 uye yakapa kuwedzera kudiki kwesimba kusvika ku260 kW asi torque yakakura kusvika 510 Nm.

Yakabatana zvakanyanya neinozivikanwawo seinjini yeLS2, iyo L76 yaive yechokwadi bhiza reiyo LS pfungwa. Iyo nyowani VE Commodore (uye Calais) V8 yakaramba iine L76, asi iyo 2 yakatevedzana VE uye yekutanga nhevedzano yekupedzisira yeAustralia Commodore, iyo VF, yakachinjirwa kuL77, iyo yaive iri L76 ine flex-fuel kugona. .

Mhando dzemazuva ano dzeVF Series 2 V8 dzachinja kuita injini ye6.2-litre LS3 (yaimbonzi HSV modhi chete) ine 304kW ne570Nm yetorque. Iine mbiri-module kupera uye kunyatsotarisisa kune zvakadzama, aya maLS3-powered Commodores zvave zvinhu zvemuunganidzi.

Yekupedzisira yeCommodore SS yaifambiswa neinjini ye6.2 litre LS3 V8.

Zvichakadaro kuHolden Special Vehicles, iyo LS-mhuri injini yakapawo simba Commodore-based zvigadzirwa kubva 1999, nekuchinja kune 6.0-litre L76 yeVZ-based mota muna 2004 uyezve ku6.2-liter LS3 yeVZ-based mota. . E-akatevedzana mota kubvira 2008.

HSV yanga ichichinjisa tsandanyama dzayo kwekupedzisira kumhanya kwemota dzayo dzeGen-F neSeries 2 vhezheni inofambiswa neinjini ye6.2-litre LSA inokwana 400kW ne671Nm.

Iyo GTSR W1 ichagara iri yakanakisa HSV zvachose.

Asi yanga isiri iyo HSV yekupedzisira, uye yakaganhurirwa kuvaka GTSR W1 yakashandisa ruoko rwakavakwa shanduro yeLS9 injini ine 6.2 litre displacement, 2.3 litre supercharger, titanium yekubatanidza tsvimbo uye yakaoma sump lubrication system. Mhedzisiro yacho yaive 474 kW yesimba uye 815 Nm ye torque.

Injini dzeLS dzakagadzirirwa sevhisi yeAustralia dzaisanganisira yakagadziridzwa 5.7kW Callaway (USA) 300L injini yakakosha yeHSV yakaita seVX, pamwe nemotokari yemujaho yeHRT 427 yakafa yakashandisa 7.0L LS7. injini iri muchimiro chekushuvira, icho maprototypes maviri chete akavakwa purojekiti isati yaraswa sezvinei nezvikonzero zvebhajeti.

Iyo HRT 427 pfungwa.

Zvimwe zvakawanda zvakabva kuLS zviripo, zvakaita seLS6, iyo yakachengeterwa maAmerican Corvettes neCadillacs, uye ma-cast-iron-based-based versions eLS, asi haana kumbobvira asvika pamusika iwoyo.

Kuti uzive chaizvo zvauri kubata nazvo (uye izvi zvinogona kunetsa sezvo sarudzo zhinji dzeLS injini dzakapinzwa kunze kwenyika pachivande pano), tsvaga online LS injini decoder iyo inokuudza kuti ndeupi musiyano weLS wauri kutsvaga.

Chii chakanaka nezveLS?

LS inouya muhukuru hwakasiyana.

Iyo LS injini yakakwezva yakakura inotevera mumakore, zvakanyanya nekuti iri nyore mhinduro kune V8 simba.

Yakavimbika, yakasimba, uye inoshamisa inogoneka, uye inopa yakanaka simba uye torque kunze kwebhokisi.

Chikamu chikuru chekukumbira ndechekuti mhuri yeLS yakasimba. Vachishandisa dhizaini yeY-block, vagadziri vakaisa iyo LS nemabhengi matanhatu-mabhaudhi makuru (mana achibatanidza inotakura cap yakatwasuka uye maviri akachinjika akachinjika padivi pechivharo), nepo maV8 mazhinji aive mana kana maviri maviri-mabhaudhi anotakura makepisi.

Izvi zvakapa injini, kunyangwe mukesi yealuminium, kusimba kusingadaviriki uye yakashanda sehwaro hwakanakisa hwekutora simba rebhiza. Injini yedhizaini inoratidza dhizaini yepasi ichakurumidza kuratidza kuti nei iyo LS yezasi yekupedzisira yakavimbika.

Iyo LS zvakare ine compact uye isina huremu. Iyo yakareruka alloy vhezheni yeinjini yeLS inorema isingasviki mamwe mana-cylinder injini (isingasviki 180 kg) uye inogona kugadzirwa kune akasiyana maapplication.

Iyo zvakare yemahara-inofema injini dhizaini ine cylinder misoro iyo inotsigira rakawanda simba kupfuura stock.

Ekutanga maLS aive neanonzi "cathedral" madoko ekureba ekudyara zviteshi zvaibvumira kufema zvakadzika. Kunyangwe iyo hombe camshaft yepakati saizi inonzwa sekunge yakagadzirirwa tuner, uye iyo LS inogona kubata hombe camshaft isati yatanga kusimbisa iyo yese yekuvaka.

Iyo LS inorema zvishoma pane mamwe mana-cylinder injini.

Iyo LS zvakare ichiri nyore kuwana uye yakachipa kutenga. Pane imwe nguva, majunkyards aive akazara neakaputsika Commodore SSs, uye kunyangwe zvinhu zvachinja zvishoma nguva pfupi yadarika, kuwana yakashandiswa LS1 yakanaka zviri nyore pane kudzingirira 5.0-litre Holden injini.

LS inodhurawo. Zvekare, izvi zvachinja zvishoma kubva kuCovid, asi yakashandiswa LS haipwanye bhangi kana ichienzaniswa nedzimwe nzira.

Kuwedzera kune auto disassembly, Classifieds zvakare inzvimbo yakanaka yekutsvaga injini yeLS inotengeswa. Kazhinji, yekutanga LS1 injini ichave iri kutengeswa, asi gare gare mamwe ekunze shanduro dziripo zvakare.

Imwe sarudzo ndeye nyowani crate mota, uye nekuda kwehukuru hwepasirese kudiwa, mitengo yacho inonzwisisika. Ehe, iyo LSA crate injini icharamba ichikupa kunakidzwa kwakawanda, asi ndiwo muganho, uye kune yakakura siyana sarudzo uye injini specs munzira.

Pakuvaka bhajeti, yakanakisa LS injini ndiyo yaunogona kuwana nemari diki, uye akawanda anogadzirisa anogutsikana kusiya injini dzakashandiswa sezvazviri, zvichibva pakusimba uye kuvimbika kweyuniti.

Kugadzirisa kuri nyore, uye nepo spark plugs ichida kuchinjwa ega ega mamaira makumi mashanu, iyo LS ine cheni yehupenyu hwese (pane bhandi rerabha).

Vamwe varidzi vakabvisa LSs ne400,000 km kana kunyange 500,000 km pane odometer uye vakawana injini dzichiri kushanda nekupfeka kushoma kwemukati. 

Matambudziko

Early LS1s mune mamwe Holden airatidza kuve anopisa oiri.

Kana iyo LS injini ine Achilles chitsitsinho, ichava valvetrain, iyo inozivikanwa kune fry hydraulic lifters uye clog valve springs. Chero kukwidziridzwa kwecamshaft kunoda kutariswa munzvimbo ino, uye kunyangwe shanduro dzakazotevera dzichiri kutambura nekutadza kwekusimudza.

Mangwanani-ngwanani maLS1 mune mamwe maHolden airatidza kuve aipisa oiri, asi izvi zvaiwanzonzi zvakakonzerwa nekusangana kwakashata pafekitari yekuMexico kwavakavakwa.

Sezvo kunaka kwakawedzera, ndizvo zvakaitawo chigadzirwa chekupedzisira. Iyo hombe, yakapfava, isina kudzika crankcase zvinoreva zvakare kuti mota inofanirwa kunge iri padanho rakakwana kana uchitarisa mwero wemafuta, sezvo kona diki inogona kukanda pakuverenga uye ingave yakakonzera kumwe kunetseka kwekutanga.

Varidzi vazhinji vakanetsana nerudzi rweoiri kuderedza kushandiswa kwemafuta, uye mhando yemafuta enjini inodiwa kune LS.

Varidzi vazhinji vanoshuma imwe piston inogogodza kunyangwe neinjini nyowani, uye ichigumbura, hairatidzike iine mhedzisiro yenguva refu painjini kana hupenyu hwayo.

Muzviitiko zvakawanda, kugogodza kwepiston kwakanyangarika nekuchinja kwegiya rechipiri mukati mezuva uye hakuna kudzoka kusvika panotanga kutonhora kunotevera.

Mune dzimwe injini, kugogodza kwepiston chiratidzo chekuparadzwa kuri kuuya. MuLS, semamwe akawanda emagetsi emagetsi emagetsi, zvinoita sekunge ingori chikamu chechibvumirano.

Chinja

Ingori 7.4-litre mapatya-turbocharged V8 muHonda Civic… (Mufananidzo wechikwereti: LS nyika)

Nekuti yakavimbika kudaro, inogoneka chikuva, injini yeLS yave yakakurumbira nematuner kutenderera pasirese kubva pazuva rekutanga.

Nekudaro, yekutanga gadziriso yakaitwa nevaridzi veAustralia vekare veLS1 V8s yaive yekubvisa chivharo cheinjini yepurasitiki uye kushandisa mabhuraketi echivharo chemasheya kuisa kavha inoyevedza yezvikamu zviviri zvemashure.

Mushure meizvozvo, kutarisisa kwaiwanzo kutendeukira kune yakawedzera hukasha camshaft, imwe humburumbira musoro basa, kutonhora kwemhepo, uye fekitori kugadzirisa komputa.

Iyo LS inopindurawo zvakanaka kune yemhando yekupedza simba system, uye vamwe varidzi vakave nebudiriro yakakura nekungoisa yemahara-inoyerera exhaust system. Dzimwe nguva kunyange iyo mhinduro system inoburitsa zvishoma zvingangoita.

Mukuwedzera, zvinenge zvose zvinogona kuitwa nejini zvakaitwa neLS V8. Mamwe madhifita akatokanda jekiseni remagetsi remagetsi uye akaisa maLS avo neakakwirira-akakwira manifold uye hombe carburetor ye retro styling.

Vanhu vachakanda LS chero chinhu. (Mufananidzo wechikwereti: LS world)

Muchokwadi, kana iwe uchinge wapfuura iyo yakakosha LS kudzoreredza kit, zvigadziriso hazviperi. Takaona akawanda mapatya- uye single-turbo LS V8s (uye injini inoda supercharging, sezvinoratidzwa neiyo supercharged vhezheni yeLSA).

Imwe mafambiro epasi rose ndeyekukwana maLS kune zvese kubva kumota dzemujaho kusvika kumota dzemumigwagwa dzemhando dzese nehukuru.

Iwe unogona kutenga seti yemamongi einjini kuti igadzirise iyo LS kune yakakura siyana yemagadzirirwo uye modhi, uye huremu hweiyo alloy LS zvinoreva kuti kunyangwe mota diki dzinogona kubata kurapwa uku.

MuAustralia, makambani akadai seTuff Mounts anewo makiti ekukwira anowanikwa kune akawanda magadzirirwo eLS.

Kuzivikanwa kweinjini kunoreva kuti hapana kana chikamu chimwe chete chausingakwanise kutengera iyo LS V8, uye hapana application apo haisati yashandiswa. Izvi zvinoreva kuti musika wakakura uye hwaro hweruzivo hwakakura.

Mhuri yeLS inogona kunge iri pushrod mavharuvhu maviri, asi maererano nemabatiro aakaita pasirese, hapana akawanda (kana aripo) mamwe maV8 injini anogona kuifananidza.
