Engine 3ZR-FE
3ZR-FE ndi injini yamafuta yamkati yamasilinda anayi. Njira yogawa gasi ndi valve 16, yopangidwa molingana ndi dongosolo la DOHC, yokhala ndi ma camshaft awiri. Silinda ya silinda ndi chidutswa chimodzi, kusuntha kwa injini yonse ndi malita awiri. Nthawi yoyendetsa galimoto - unyolo.
Chowunikira chapadera pamndandandawu chinali kukhala Dual VVT-I ndi Valvematic, opangidwa ngati yankho ku dongosolo la Valvetronic kuchokera ku BMW ndi VVEL kuchokera ku Nissan.
Dual VVT-I ndi njira yotsogola yanzeru yama valve yomwe imasintha nthawi yotsegulira osati kungolowetsa komanso ma valve otulutsa mpweya. Koma, monga momwe zasonyezera, palibe chatsopano chomwe chapangidwa. Njira yotsatsira yokha ya Toyota, yopangidwa poyankha kutukuka kwa omwe akupikisana nawo. Mawotchi amtundu wa VVT-I tsopano ali pamakina anthawi zonse, osalumikizidwa ndi mayamwidwe okha, komanso ma valve otulutsa mpweya. Kugwira ntchito motsogozedwa ndi makompyuta apakompyuta, dongosolo la Dual VVT-I limapangitsa mawonekedwe a injini kukhala ofanana kwambiri malinga ndi liwiro la torque motsutsana ndi crankshaft.
Njira yopambana kwambiri inali ya Valvematic air-fuel ratio control system. Kutengera momwe amagwirira ntchito injini, kutalika kwa valavu yotengera kumasintha, ndikusankha mawonekedwe abwino amisonkhano yamafuta. Dongosololi limayang'aniridwa ndi gawo lamagetsi lamagetsi lomwe limasonkhanitsa mosalekeza ndikusanthula deta pakugwira ntchito kwa injini. Zotsatira zake, dongosolo la Valvematic ndi lopanda kuviika ndi kuchedwa komwe kumayenderana ndi njira zoyendetsera makina. Zotsatira zake, injini ya Toyota 3ZR-FE idakhala yotsika mtengo komanso "yomvera" mphamvu, yopambana muzochita zake kuposa injini zoyatsira zamkati zamafuta.
Chochititsa chidwi. Dziko la Brazil, lomwe limapanga shuga wambiri padziko lonse lapansi, limasandutsa bwino shuga kukhala ethanol, yomwe imagwiritsidwa ntchito ngati mafuta a injini zoyatsira mafuta mkati. Kumene, "Toyota" sanafune kusiya msika woteroyo, ndipo mu 2010 adakonzanso chitsanzo cha 3ZR-FE kuti agwiritse ntchito mafuta amtunduwu. Chitsanzo chatsopanocho chinalandira chiyambi cha FFV ku dzina, kutanthauza "injini yamafuta ambiri".
Mphamvu ndi zofooka za 3ZR-FE
Kawirikawiri, injiniyo inali yopambana. Yamphamvu komanso yotsika mtengo, imawonetsa mawonekedwe okhazikika a torque pafupifupi pafupifupi liwiro lonse la crankshaft. Kukonzekera dongosolo la Valvematic linali ndi zotsatira zabwino pa "kuyankha" kwa 3ZR-FE kukanikiza chowongolera chowongolera komanso kusintha kwadzidzidzi kwa katundu.
Zoyipa zake ndizambiri. Kusowa kokonza miyeso ya cylinder block. The nthawi unyolo pagalimoto, akuyendera kotero molephera, kuti ndi nthawi kulankhula za gwero injini 200 Km, ndiye, mpaka unyolo kulephera.
Pokhudzana ndi dongosolo la Dual VVT-I, mafuta a 3ZR-FE ayenera kusankhidwa mosamala kwambiri. Kuchuluka kwambiri, kungayambitse kuwonongeka kwa makina ogawa gasi. Akatswiri ambiri amalangiza 0w40.
