Toyota 1HZ injini: zvese zvaunoda kuziva

Iyo 1HZ inopa kuvimbika kwezuva nezuva uye kuvimbika, pamwe nekushanda kwakanaka uye hupfumi hwemafuta.

Turbocharged injini dzedhiziri dzave kushandiswa kubva pakutanga kwezana ramakore rapfuura, asi hapana kana mota yemumugwagwa mazuva ano isina turbocharger yekuwedzera simba uye kugona. 

Asi handizvo zvaigara zvakadaro, uye injini yedhiziri yeToyota 1HZ iri muLandcruiser renji zvirokwazvo inofanirwa kutorwa semuchinda wemadhiziri anongogara achidiwa. 

Imwe nhengo yeToyota HZ injini boka, 1 mu1HZ inoratidza kuti inhengo yemhuri yechizvarwa chekutanga.

Hakusi chete kuti Toyota 1HZ dhiziri inokwanisa kuita basa returbodiesel diki, icharamba ichidaro kwehafu yemiriyoni mamaira, vamwe vatyairi vachishuma miriyoni yemamaira pasati padiwa basa guru. 

Wedzera kune iyo yakanakisa kuvimbika kwezuva nezuva, kushanda zvakanaka uye hupfumi hwemafuta, uye iwe unogona kuona nei iyo 1HZ, nepo isiri mumhanyi, yave inodiwa nevafambi vakareba uye vari kure. 

Chero wongororo yeinjini ye1HZ inogara ichinongedza kuti iyi injini yehupenyu hurefu isingakundike nekukasira. Zvichida dambudziko guru ndere 1HZ yemafuta edzimotokari, ayo achabva pamarita gumi nerimwe kusvika pagumi nematatu pa11km.

Iyi iri pamotokari yakajairwa pakumhanya kwemumugwagwa uye inokwira zvakapetwa kaviri kana ichidhonzwa. Iyo inosarira kuseri kwemotokari dzemazuva ano mbiri, asi haina kushata nekuzara-saizi XNUMXWD zviyero.

Hunhu hwemhanza 1HZ injini haifanire kuburitsa zvakavanzika zvayo. Asi, iko kusanganiswa kwezvinhu zvemhando yepamusoro, hunyanzvi hwekuita, uye dhizaini yakasimba yakaita kuti 1HZ ive mudziyo unoremekedzwa zvakadaro. 

Inotanga neyakakanda simbi block uye cylinder musoro (inowanikwa zvakanyanya mumajini edhiziri kunyangwe nhasi). Iyo 4.2 litre (4164 cc kuve chaiyo) 1HZ injini ine bore uye sitiroko ye94mm uye 100mm. 

Crank inomhanya mumabhengi makuru manomwe. Injini iyi inline six-cylinder injini ine imwechete pamusoro camshaft (inotyairwa nemazino rabha bhandi) uye mavharuvhu maviri pahumburumbira.

Injini ye4.2 litre inline six-cylinder inogadzira 96 ​​kW/285 Nm yesimba. (Mufananidzo wechikwereti: Wikimedia Commons)

Iyo 1HZ inoshandisa isina kunanga jekiseni tekinoroji uye ine compression reshiyo ye22.4:1. Simba rinonzi 96 kW pa3800 rpm uye 285 Nm pa2200 rpm. 

Iyo 1HZ injector pombi dhizaini icharatidzawo kuti injini inoshandisa jekiseni rechikoro chekare uye kwete tekinoroji nyowani yakajairika-njanji yedhiziri. 

Iko kuumbwa kwesimbi kuvakwa kwemota kunoreva kuti yakasimba, asi huremu hwe1HZ mota hunenge 300kg. Huwandu hwe1HZ injini yemafuta i9.6 malita kana yakaoma yazadzwa.

MuAustralia, iyo 1HZ yaive sarudzo yakakurumbira mune makumi masere akateedzana, iyo yakavambwa muna 80 uye yakazoonekwa seyakanakisa LandCruiser Toyota yakamboitwa (iyo-nyowani-nyowani mazana matatu yakatevedzana yanga isati yazviratidza kune iro zita). 

Mune 80 akatevedzana fomu, 1HZ yakatengeswa padivi pepeturu matanhatu-silinda uye 1HDT turbodiesel shanduro dzemotokari imwe chete, uye izvi zvakaenderera mberi neiyo 100 yakatevedzana iyo yakaona 1HZ yakaiswa kune base modhi Standard variant (technically the 105 series). 

Nechitarisiko chekare uye akawanda e-off-road kugona, hazvishamise kuti makumi masere anoramba akakurumbira. (Mufananidzo wechikwereti: Tom White)

Izvi zvakapfuurira mumotokari iyi kusvikira 2007, apo 200 dzakatevedzana dzakaonekwa. 

Mumutsara wehorse, Toyota 1HZ yakaonekwa mu75 Series uye Troop Carrier muna 1990 uye yakatengeswa kusvika 2007 apo yakazotsiviwa nematurbodiesel akasiyana. Diziel re1HZ raishandiswawo mune mamwe mabhazi eToyota Coaster.

Zvine hutsinye, kuti uwane 1HZ muToyota yako nyowani, waifanira kutenga yakazara saizi LandCruiser, sezvo Prado isina kumbobvira yawana iyo injini. 

Iwe haugone kuwana iyo LandCruiser 1HZ ine otomatiki kutapurirana kana; kana iri injini ye1HZ, kuchinja kwemaoko kwaive kwauri.

Kune matambudziko mashoma neinjini ye1HZ. Kunze kwemakesi mashoma emisoro yakatsemuka silinda munzvimbo yekupisa, nhau dzakanaka. 

1HZ cylinder head gaskets harisi dambudziko chero bedzi injini isati yanyanya kupisa, uye bhandi renguva re1HZ hariratidzike sedambudziko kana richinge rashandurwa 100,000 km yega yega. 

Iwo makumi manomwe neshanu akateedzana akagamuchira chikamu-nguva system ine kesi yekuchinjisa inopa maviri akasiyana seti egiya reshiyo.

Kunzwisisa kunoraira kuti pombi yemafuta ye1HZ inoda kutariswa mushure memakiromita angangoita mazana mana ezviuru, uye varidzi vazhinji vanosarudza kuvakazve silinda yemusoro panguva imwe chete. 

Kumwe kugadzirisa kuri nyore, kunyangwe nzvimbo ye1HZ thermostat pazasi pechivharo inoita kuti zviome kuwana pasina kubvisa alternator.

Ehe, hapana chinogara nekusingaperi, uye kana iyo 1HZ yapera, varidzi vazhinji vanongofunga kutenga yakashandiswa 1HZ ine mashoma mamaira uye kuitengesa mairi. 

1HZ injini rondedzero mune iyi kesi yakakurumbira, asi vamwe varidzi vanosarudza kuvakazve injini yavanotova nayo. 

A 1HZ yekuvaka patsva kit inosanganisira mhete, mabearings uye gaskets inogona kutengwa nemari inosvika madhora zana nemakumi mashanu, asi kana uchida kugadzira injini ine turbocharged gadzirira kushandisa zvakapetwa kaviri kune kit iyo inosanganisira yakaderera compression pistons. 

Iwo 105 akatevedzana aive munzira dzakawanda kuenderera kwe80 akatevedzana.

Zvinodawo basa rakawanda kana ukasaita basa racho iwe pachako asi uchifunga nezvezviyero uye machining eiyo iripo crankshaft uye cylinder madziro.

Injini yakanaka, inomhanya yakashandiswa inogona kuwanikwa kwezviuru zvishoma zvemadhora, nepo mayunitsi akavakwa patsva (ane turbo kugona) anogona kuwanikwa ne5000 kusvika $10,000 uye kumusoro kana iwe uchida chimwe chinhu chinonyengera. 

Remanufactured mauniti anowanikwa zvakanyanya kubva kumakambani ane hunyanzvi murudzi urwu rwebasa, asi iwe ucharamba uchingoda kupa yekutsiva huru mota.

Zvichida kuenzanisa kunowanzoitwa nevanhu ndeyekurukurirano yekare ye1HZ vs 1HDT, sezvo 1HDT inotengeswa pamwe chete ne1HZ mu80 uye 100 motokari dzakatevedzana, asi mazuva ano inoita mari yakawanda sechipo chakashandiswa. 

Sei? Simply nekuti 1HDT iturbocharged dhiziri injini uye somugumisiro ine simba rakawanda uye torque (151kW/430Nm pachinzvimbo 96kW/285Nm). 

Bvunza chero Toyota LandCruiser fan uye vanozoziva chinonzi 1HD FTE injini. Vanogona kunge vaine injini kodhi tattoo!

Izvi zvinopa injini ye turbocharged mukana mukuru wekuita mumugwagwa, asi kunze kwemugwagwa, uko vashandisi vanotonga, kureruka uye kuvimbika kwe1HZ (uye kusavapo zvachose kwemagetsi) inoramba iri injini yekusarudza kune vamwe.

Kubva pakuona kwehunyanzvi, pane mimwe misiyano, zvinosanganisira nyaya yekuti majekiseni e1HZ anoshanda mukamuri yekupisa (ichiita kuti 1HZ ive injini yejekiseni isina kunanga), nepo 1HDT iri dhizaini yakananga jekiseni uko kupisa kunotanga mukati. 

Nechikonzero ichi (pakati pezvimwe zvinhu) misoro yehumburumbira yeinjini mbiri haichinjike, uye turbocharged injini yekutsikirira yakasiyana reshiyo inoreva kuti zvikamu zvepasi hazvienderane.

Kunyangwe Toyota isina kumbobvira yapa 1HZ turbo injini, 1HZ turbo kit yakapihwa mumarket yekumashure kune izvo chete. Zvakanaka kutaura kuti mamwe acho akagadzirwa zviri nani pane mamwe, asi chero zvakadaro, varidzi ve1HZ turbo injini vanowanzoisa pyrometer (kutarisa kupera kwegasi tembiricha uye kuratidza kuti injini iri kushanda nesimba sei) uye kunyatsoongorora kuverenga kweizvi. sensor. tsono.

Yakakurumbira turbocharger aftermarket mhinduro mumakore apfuura anosanganisira Safari Turbo 1HZ, AXT Turbo 1HZ uye Denco Turbo 1HZ kits. 

Iyo 1HDT yakatengeswa padivi pe1HZ mu80 uye zana dzakatevedzana mota. (Mufananidzo wechikwereti: Tom White)

Nheyo dzekiti imwe neimwe dzaive dzakafanana; a 1HZ turbo manifold, iyo turbocharger block pachayo uye inodiwa pombi yekubatanidza iyo yese. 

Kuwedzera kune ekutanga turbo kits, akawanda tuner anokurudzira kuwedzera compensator uye, kune yakanyanya kuita, intercooler. 

Zvisinei, muchiitiko chimwe nechimwe chinangwa chakanga chimwe chete; kuvandudza kuita kwekutyaira uye kukurumidza, kunyanya kana uchidhonza. A basic turbo kit inodhura pakati pe $3000 ne $5000 pamwe nekuisa.

Zvichakadaro, varidzi vanoyemura kureruka kwe1HZ vari kuyedza kubvisa turbocharging uye panzvimbo pezvo vanoshandisa nzira dzechinyakare dzekuwedzera kugona kweinjini. 

Kune varidzi ava, yakanakisa turbo ye1HZ yanga isiri turbo zvachose. Kana iwe usingade imwe kukwidziridzwa, iyi zvakare nharo inoshanda. 

Muzviitiko zvakawanda, varidzi vakatendeukira kune yakajairwa kutendeuka uye yemhando yekuisa exhaust, kusanganisira 1HZ extractors uye yakatwasuka-kuburikidza (kazhinji 3.0-inch) exhaust system, kuti vawane zvavanoda.
