Izinjini zeToyota Sequoia
Okuqukethwe
IToyota Sequoia (Toyota Sequoia), isizukulwane sokuqala nesesibili anosayizi ogcwele, amaSUV amakhulu kunawo wonke ngemuva kweMega Cruiser. Le moto enkulu yaqala ukuvela ngo-2000 njengemodeli yangonyaka ozayo. Ngokwentengo, ibingaphezu kwe-4Runner ephakathi nendawo, kodwa ingaphansi kweLand Cruiser.
Ngaphezu kwalokho, i-Sequoia ithathe indawo yeToyota Tundra, ngesisekelo esakhiwe ngayo. Njengamanje, ithola isidingo ezimakethe zase-USA, Canada, Mexico, Puerto Rico, Middle East.
Isikhathi sokukhiqiza nokudayiswa kwesizukulwane sokuqala sale mishini kwakuyinkathi esukela ku-2001 kuya ku-2007. Kusukela ngo-2003, imoto ifakwe:
- uhlelo lokulawula ikhompuyutha ebhodini;
- ukulawula isimo sezulu;
- amasondo amaningi.
Idizayini ye-suspension yangaphambili iyafana nePrado 120, i-suspension yangemuva ifana neLand Cruiser 100. Ngosizo lwe-dual-zone control control, ungakwazi ukulungisa ukugeleza kubagibeli abangemuva bese ufaka umoya ophansi we-trunk.
Izihlalo zomugqa wesithathu zisuswa kalula futhi zifakwe endaweni, futhi umugqa wesibili ugoqa ohlangothini lwemoto, ukwandisa kakhulu indawo yemithwalo.
Zombili izizukulwane zale mishini zaklanywa futhi zakhelwa imakethe yaseNyakatho Melika. Nakuba inkampani ngo-2010 yamemezela ukukhishwa kwale SUV emshinini wokuhlanganisa ngenxa yokuncipha kwesidingo, ngesikhathi esifanayo kwashintshwa injini enkulu futhi enamandla kakhulu. Idonsa ngamagiya amahlanu ozishintshayo nayo ishintshwe kwafakwa enamagiya ayisi-6. Amandla abe maningi enguqulweni edonsa ngamasondo angemuva, kanti iSUV enkulu ishaye u-100 km/h ngemizuzwana engu-6,1.
Yiziphi izinjini ezifakwe ezizukulwaneni ezahlukene zezimoto
Le SUV enkulu yeToyota Sequoia ifakwe izinhlobo ezintathu zezinjini ezisebenza kahle, eziyinhloko zibalwe kuleli tafula:
| Isizukulwane, ukulungisa kabusha | Enza injini | Ivolumu, l | Amandla, kWt. | I-Torque, Nm |
|---|---|---|---|---|
| 1 | 2UZ-FE | 4.7 | 177 | 427 |
| 2UZ-FE | 4.7 | 177 | 427 | |
| 1, iqa | 2UZ-FE | 4.7 | 208 | 441 |
| ling | 2UZ-FE | 4.7 | 208 | 441 |
| 2 | 1UR-FE | 4.6 | 228 | 426 |
| 2UZ-FE | 4.7 | 201 | 443 | |
| 3UR-FE | 5.7 | 280 | 544 | |
| 3UR-FE | 5.7 | 280 | 544 | |
| 3UR-FE | 5.7 | 280 | 544 | |
Iyunithi yamandla yesizukulwane sokuqala se-Sequoia kwakuyinjini engu-1-litre V8, ehambisana no-4,7-speed automatic transmission. Ngemva kokulungiswa kabusha ngo-4, isistimu ye-valve ye-VVT-i eguquguqukayo yavela enjini futhi yaba namandla kakhulu - 2004-273 hp. nge., futhi u-gearbox wangaphambili wathathelwa indawo ngu-282-speed.
Isizukulwane sesibili seToyota Sequoia esigcwele usayizi SUV sihlinzekwa nge-back-wheel drive noma all-wheel drive. Imoto ifakwe izinjini ezingu-8-cylinder kanye ne-automatic transmission.
Zonke izinjini ezivuthayo zangaphakathi ezifakwe kuSequoia bezinguphethiloli. Izinjini ebezisezimotweni zesizukulwane sokuqala zichithe amalitha kaphethiloli angu-100 ohambweni lwamakhilomitha angu-16,8 uma lo mnyakazo ubuxubile. Ngemuva kokulungiswa kabusha ngo-2004, ukusetshenziswa kwehle kwafinyelela ku-15,7 amalitha. Esizukulwaneni sesibili sezimoto, kuye ngohlobo lwenjini, ukusetshenziswa kukaphethiloli kwakusukela ku-16,8 kuya ku-18,1 amalitha. Amathangi kaphethiloli abenomthamo osuka ku-99 kuya ku-100 wamalitha.
Yiziphi izinjini ezidume kakhulu
Izinjini zohlobo lwe-2UZ-FE, ezimelelwa ukuguqulwa okuningana, okuthinte amandla abo (240, 273, 282 hp), kusukela ngo-2000 kuze kube manje, ziyaqhubeka nokufakwa kuToyota Sequoia yamazinga amabili okunquma. Kuyacaca ukuthi ingqikithi yalezi zinjini, ezifakwe kuphela kulezi zinhlobo zeToyota, zidlula izinhlobo ezimbili ezisele zamayunithi kagesi.
Imboni yamandla yohlobo lwe-1UR-FE ifakwe ekucushweni okukodwa kwale moto i-2007 AT SR4.6 kusukela ngo-5 kuze kube namuhla. Ngakho-ke ukwanda kwayo yikona okuphansi kwezinjini ezintathu.
Indawo ephakathi nendawo ithathwa yinjini yohlobo lwe-3UR-FE, okuthe kusukela ngo-2007 kuze kube manje isinikeze amandla ama-trim amathathu eToyota Sequoia. Mhlawumbe, uma kunikezwe ukusetshenziswa kwalezi zinjini kwamanye amamodeli weToyota nabanye abakhiqizi, isithombe singashintsha ngandlela-thile.
Lezi zinjini zazifakwe kumaphi amamodeli omkhiqizo?
Kanye neToyota Sequoia, injini ye-3UR-FE yasebenza njengesikhungo samandla kwamanye amamodeli, imininingwane yawo efingqiwe kuthebula elingezansi:
| Enza injini | Toyota | I-Lexus | |||||
|---|---|---|---|---|---|---|---|
| eNobi | ngaphezulu | Crown | Omkhulu | Soarer | I-4Runner | I-Land Cruiser | I-Tundra |
| 1UZ-FE | + | + | + | + | + | ||
| 2UZ-FE | + | + | + | + | |||
| 3UR-FE | + | + | + |
Njengoba ubona, wonke ama-motor amathathu afakwe ikakhulukazi kuma-SUVs asindayo futhi anamandla, futhi azibonakalisa kuphela ohlangothini oluhle, kokubili ngezimfanelo ezishukumisayo nokuthembeka.
Iyiphi injini engcono ukukhetha imoto
Kuncike ekuthandeni komuntu siqu kanye nokutholakala kwemali. Ngakolunye uhlangothi, ukukhetha kunzima ngenxa yokuthembeka okuphezulu nokusebenza kahle kwawo wonke ama-motor amathathu. Uyini umehluko wabo wezobuchwepheshe?
Kusukela ngo-1997, uhlelo lwe-VVTi luye lwavela ku-1UZ FE, okwenza kube lula ukwandisa ububanzi be-valve yokungena. I-gasket ehlukile ifakwe ekhanda le-cylinder, i-ACIS intake manifold yasetshenziswa. Isistimu yokushisa ethuthukisiwe, ama-piston kanye ne-throttle ye-electronic efakiwe. Ngemuva kokulungiswa kabusha, isilinganiso sokucindezela namandla enjini anda.
Le moto ibaluleke kakhulu ngenxa yamandla ezinto zokwakha, okwandisa insiza. Isibonelo, i-1UZ FE aluminium silicon alloy pistons imelana nokushisa okuphezulu, okuqinisekisa ukubekezelelana okuqinile kanye nokulingana okuqinile kumasilinda. Uchungechunge lwezinjini lwe-2UZ lwaba yimpumelelo, ngaphandle kokungalungi kokuklama nokushiyeka. Resource 2UZ-FE - ngaphezu kwezigidi ezingu-0,5 km.
I-cast-iron cylinder block yandisa ukwethembeka nokuqina kwemoto.
Ngo-2005, kulezi zinjini kwavela uhlelo lwe-VVTi, olwathinta amandla, olwanda lwaba ngu-280 hp. Nge. Izimoto zochungechunge lwe-2UZ zifakwe amabhande wesikhathi esinama-toothed ashintshwa ngemva kwamakhilomitha ayizinkulungwane eziyi-100.
Injini ye-3UR-FE ihlukaniswa ngevolumu enkulu, insimbi engagqwali yokukhipha izinto eziningi, ukuba khona kwama-catalysts okuhlanzwa kwe-exhaust engu-3, njll. Ikhiqizwa kokubili nge-turbocharger kanye nenguqulo ye-atmospheric. Kanye nophethiloli, akunzima ukuwaguqulela ku-biofuels noma igesi. Le moto, ngokulungiswa okufanele, izoba nokwethembeka okuhle kakhulu nokukhuthazela. Ngokweminye imibiko, uyakwazi ukuhamba ibanga elingu-1,3 million km ngaphandle kokuphazamiseka okukhulu.
