Injini yeToyota 2AR-FE
Uchungechunge lwenjini ye-Toyota AR luqale umlando walo muva nje - amayunithi okuqala avela ngo-2008. Njengamanje, lezi izinjini ezidumile ezihlonishwa kakhulu ngabashayeli bezimoto baseJapan e-United States naseCanada. Nokho, amanye amalungu omkhaya asakazeka emhlabeni wonke.
Imininingwane 2AR-FE
Ngenjini ye-2AR-FE, izici zadalwa kucatshangelwa ukuguquguquka kokusetshenziswa kwayo. Idatha yezobuchwepheshe yeyunithi ikuvumela ukuthi uyifake cishe kunoma iyiphi imoto yokukhathazeka, ngaphandle kwabameleli bayo abancane kanye nama-SUV amakhulu. Izinkomba eziyinhloko zenjini zimi kanje:
| Ububanzi | Ama-2.5 amalitha |
| Inani lamasilinda | 4 |
| Amandla | 169 ukuze 180 amahhashi |
| Ububanzi besilinda | 90 mm |
| Ukushaya kwesibhamu | 98 mm |
| Uhlelo lokusabalalisa igesi | I-DOHC |
| I-Torque | kusukela ku-226 kuya ku-235 N*m |
| I-EFI electronic fuel injection system | |
| Isilinganiso sokucindezela | 10.4 |
Isistimu kaphethiloli enokwethenjelwa namandla alinganiselwe aprofetha injini ukuthembeka okunjalo ekusebenzeni, lapho izinjini zeToyota zazidume ngakho ekuqaleni kwawo-90s ekhulwini elidlule. AmaJapane ashiya ubuchwepheshe obuningi obuphawula isizukulwane sesithathu sezinjini zeqembu. Ngenxa yalokhu, iyunithi yaqala ukulinganisa amakhilogremu angu-147, ukukhiqiza amandla amancane ngevolumu esebenzisekayo, kodwa ngesikhathi esifanayo yaqala ukonga uphethiloli. Uma iqhathaniswa neyandulelayo, injini engu-2AR-FE idla uphethiloli ongaphansi ngo-10-12%. Insiza ekhulayo ye-motor nayo iyathakazelisa. Manje ingalungiswa, ngoba amabhulokhi amasilinda e-aluminium anezindonga ezincane ayinto yesikhathi esidlule. Ngaphambi kokulungisa kuqala ngesikhathi sokusebenza okujwayelekile, injini ingakwazi ukushayela amakhilomitha ayizinkulungwane ezingu-200. Khona-ke ukulungiswa kuzodinga izinkulungwane ezingama-70-100 ngayinye. Kodwa iyunithi ayikwazi ukubizwa ngokuthi i-millionaire - umthombo omkhulu ungamakhilomitha ayizinkulungwane ezingu-400-500.
Izinkinga zobuchwepheshe
Kuze kube manje, ayikho idatha eningi kakhulu ngezinkinga ezidumile ze-Toyota 2AR-FE izinjini. Esikhathini esingengakanani esidlule, ukukhiqizwa kwezimoto ngale yunithi kwaqala e-Indonesia, e-China, eTaiwan, futhi ngaphambi kwalokho, ukusebenza kweyunithi kwenzeka ezimweni ezinhle kakhulu e-USA, Canada naseJapane.
Futhi nokho, iyunithi inezifo eziningana zezingane. Lokhu ukungqongqoza endaweni yebhande lesikhathi. Ama-actuator okushintsha isikhathi se-VVT ayangqongqoza. Ezimweni lapho uphethiloli ongemuhle kakhulu, ahluleka ngokushesha.
Futhi, ukusebenza okuthembekile kwephampu yesistimu yokupholisa kwaqashelwa. Uvame ukuvuza.
Yonke enye i-2AR-FE ayizifaki engozini njengeyunithi yamandla embi. Kuze kube manje, ukubuyekezwa kwe-2AR-FE kusivumela ukuthi siyibheke njengenye yamayunithi angcono kakhulu esizukulwane sakamuva seToyota.
Ifakwe kuphi injini?
Uhlu lwamamodeli iyunithi eliwasethayo alilikhulu kangako. Lawa amamodeli alandelayo:
- RAV4
- I-Camry (ngezinguqulo ezimbili);
- I-Scion TC.
Mhlawumbe, esikhathini esizayo, umugqa wezimoto lapho injini ye-2AR-FE ifakiwe izokhula, ngoba iyunithi izibonakalisa kuphela ohlangothini oluhle kakhulu.
