Toyota 2AR-FE injini
Toyota AR injini mndandanda anayamba mbiri yake posachedwapa - mayunitsi woyamba anaonekera mu 2008. Pakadali pano, awa ndi injini zodziwika bwino zomwe zimalemekezedwa kwambiri ndi madalaivala agalimoto aku Japan ku United States ndi Canada. Ngakhale zili choncho, ena a m’banjamo akufalikira padziko lonse lapansi.
Zithunzi za 2AR-FE
Kwa injini ya 2AR-FE, mawonekedwe adapangidwa poganizira kusinthasintha kwakugwiritsa ntchito kwake. Deta yaukadaulo ya chipangizocho imakuthandizani kuti muyike pafupifupi galimoto iliyonse yamavuto, kupatula oimira ake ang'onoang'ono ndi ma SUV akulu. Zizindikiro zazikulu za injini ndi izi:
| Chiwerengero | 2.5 lita |
| Chiwerengero cha masilindala | 4 |
| Kugwiritsa ntchito mphamvu | 169 mpaka 180 mahatchi |
| Cylinder m'mimba mwake | 90 мм |
| Kupweteka kwa pisitoni | 98 мм |
| Njira yogawa gasi | DoHC |
| Mphungu | kuchokera 226 mpaka 235 N*m |
| EFI electronic fuel injection system | |
| Chiyerekezo cha kuponderezana | 10.4 |
Dongosolo lodalirika lamafuta ndi mphamvu zolimbitsa zimanenera injini kudalirika kotereku, komwe injini za Toyota zidadziwika kumayambiriro kwa zaka za m'ma 90 zazaka zapitazi. Anthu a ku Japan anasiya matekinoloje ambiri omwe anali chizindikiro cha m'badwo wachitatu wa injini zamagulu. Chifukwa cha ichi unit anayamba kulemera makilogalamu 147, kupanga mphamvu zochepa pa voliyumu zigwiritsidwe, koma pa nthawi yomweyo anayamba kupulumutsa mafuta. Poyerekeza ndi m'mbuyo mwake, injini ya 2AR-FE imagwiritsa ntchito mafuta ochepera 10-12%. Kuwonjezeka kwa gwero la injini kumakhalanso kosangalatsa. Tsopano ikhoza kukonzedwa, chifukwa mipanda yopyapyala yokhala ndi mipanda ya aluminiyamu ndi yakale. Pamaso kukonzanso koyamba pa ntchito yachibadwa injini akhoza kuyendetsa makilomita 200 zikwi. Ndiye kukonza kudzafuna aliyense 70-100 zikwi. Koma unit sangakhoze kutchedwa miliyoneya mwina - gwero pazipita 400-500 makilomita zikwi.
Mavuto aukadaulo
Mpaka pano, palibe deta zambiri pamavuto otchuka a injini za Toyota 2AR-FE. Osati kale kwambiri, kupanga magalimoto ndi unit anayamba Indonesia, China, Taiwan, ndipo zisanachitike, ntchito ya unit unachitika mu zinthu zabwino mu USA, Canada ndi Japan.
Ndipo komabe, gawoli lili ndi matenda angapo aubwana. Uku ndikugogoda m'dera la makina a nthawi. Othandizira kusintha nthawi ya VVT akugogoda. Ngati mafuta sali abwino kwambiri, amalephera msanga.
Komanso, sikugwira ntchito kodalirika kwambiri kwa pampu yamagetsi yozizirira kunawonedwa. Nthawi zambiri amachucha.
Zina zonse za 2AR-FE sizidziyika ngati mphamvu yoyipa. Pakadali pano, ndemanga za 2AR-FE zimatilola kuti tiziwona kuti ndi imodzi mwamagawo abwino kwambiri amtundu waposachedwa wa Toyota.
Kodi injiniyo inayikidwa kuti?
Mndandanda wa zitsanzo zomwe gawoli limayambitsa si lalikulu kwambiri. Izi ndi zitsanzo zotsatirazi:
- RAV4
- Camry (m'mitundu iwiri);
- Scion TC.
Mwinamwake, m'tsogolomu, mzere wa magalimoto omwe injini ya 2AR-FE imayikidwa idzawonjezeka, chifukwa unit imadziwonetsera yokha kuchokera kumbali yabwino.
