Injini 3ZR-FE
I-3ZR-FE iyinjini kaphethiloli evuthayo yangaphakathi enamasilinda amane. Indlela yokusabalalisa igesi iyivalvu engu-16, eklanywe ngokohlelo lwe-DOHC, enamakhamera amabili. I-cylinder block iyisiqeshana esisodwa, ukukhishwa kwenjini okuphelele kungamalitha amabili. Uhlobo lwedrayivu yesikhathi - iketango.
Okugqamile okukhethekile kulolu chungechunge kube i-Dual VVT-I kanye ne-Valvematic, ethuthukiswe njengendlela yokusabela ohlelweni lwe-Valvetronic oluvela kwa-BMW kanye ne-VVEL yakwaNissan.
I-Dual VVT-I iwuhlelo oluthuthukisiwe lwamavalvu olukhaliphile olushintsha izikhathi zokuvula zokungagcini nje ngokuthatha kodwa namavalvu okukhipha umoya. Kodwa, njengoba umkhuba ubonisile, akukho okusha okuye kwasungulwa. Iqhinga lokumaketha likaToyota kuphela, elenziwe ukuphendula ukuthuthukiswa kwezimbangi. Ama-clutch ajwayelekile e-VVT-I manje atholakala kuwo womabili ama-camshafts wesikhathi, axhumene hhayi kuphela ekungeneni, kodwa nakuma-valve okukhipha amandla. Isebenza ngaphansi kokulawulwa kweyunithi yekhompyutha ye-elekthronikhi, uhlelo lwe-Dual VVT-I lwenza izici zenjini zifane kakhulu ngokuya nge-torque uma iqhathaniswa nesivinini se-crankshaft.
Ukuqamba okusha okuphumelele kakhulu kwakuwuhlelo lokulawula isilinganiso se-air-fuel ye-Valvematic. Ngokuya ngemodi yokusebenza kwenjini, ubude be-stroke be-valve yokungena buyashintsha, kukhethwe ukubunjwa okufanele kwemihlangano kaphethiloli. Uhlelo lulawulwa iyunithi yekhompuyutha ye-elekthronikhi eqoqa ngokuqhubekayo futhi icubungule idatha yokusebenza kwenjini. Ngenxa yalokho, uhlelo lwe-Valvematic alunawo amadiphu kanye nokubambezeleka okuhambisana nezindlela zokulawula imishini. Ngenxa yalokho, injini ye-Toyota 3ZR-FE yabonakala iyunithi yamandla eyongayo futhi "esabelayo", ephakeme ngezici zayo kunezinjini ezifanayo zikaphethiloli zangaphakathi ezivuthayo.
Iqiniso elithakazelisayo. IBrazil, engumkhiqizi omkhulu kashukela emhlabeni, iwuguqula ngempumelelo ube i-ethanol, esetshenziswa njengophethiloli ezinjinini zikaphethiloli ezivuthayo. Yiqiniso, i-Toyota yayingafuni ukuyeka imakethe enjalo, futhi ngo-2010 yahlela kabusha imodeli ye-3ZR-FE ukuze isebenzise lolu hlobo lukaphethiloli. Imodeli entsha ithole isiqalo esithi FFV egameni, okusho ukuthi "injini yamafutha amaningi".
Amandla nobuthakathaka be-3ZR-FE
Ngokuvamile, injini yaba yimpumelelo. Inamandla futhi iyonga, ikhombisa izici zetorque ezinzile cishe kulo lonke ibanga lejubane le-crankshaft. Ukuhlomisa uhlelo lwe-Valvematic kube nomthelela omuhle "ekuphenduleni" kwe-3ZR-FE ekucindezeleni i-accelerator pedal kanye nezinguquko ezisheshayo ezicini zomthwalo.
Ububi buvame kakhulu. Ukungabi nezilinganiso zokulungisa ze-cylinder block. I-timing chain drive, isetshenziswe ngokungaphumeleli, kangangokuthi sekuyisikhathi sokukhuluma ngensiza yenjini engu-200 km, okungukuthi, kuze kube yilapho iketango lihluleka.
Ngokuphathelene nohlelo lwe-Dual VVT-I, amafutha e-3ZR-FE kumele akhethwe ngokucophelela. Ukujiya kakhulu, kuzoholela ekuqhekekeni kwendlela yokusabalalisa igesi. Ochwepheshe abaningi batusa i-0w40.
