Injini yeToyota 4GR-FSE
Okuqukethwe
Ngisho noma ungazi kakhulu okwakamuva emakethe yezimoto, mhlawumbe uke wezwa ngophawu lwaseJapan iToyota. Ukukhathazeka kudume emhlabeni wonke njengomdali wezimoto ezithembekile nezinjini eziqinile ngokulinganayo. Sizokhuluma ngomunye wamayunithi amandla adumile - 4GR-FSE - ngokuqhubekayo. Le injini ifanelwe ukubuyekezwa okuhlukile, ngakho ngezansi sizojwayela amandla nobuthakathaka bayo, izici nokunye okuningi, okuthinta ukusebenza kweyunithi yamandla yalolu chungechunge.
Umlando omncane
Umlando wenjini engu-2,5-litre 4GR waqala ngesikhathi esifanayo neyunithi ye-3GR. Ngemva kwesikhashana, ulayini wagcwaliswa nezinye izinguqulo izinjini. Iyunithi ye-4GR-FSE ithathe indawo ye-1JZ-GE, ivela phambi komphakathi njengenguqulo encane eyandulelayo, i-3GR-FSE. I-aluminium cylinder block yayifakwe i-crankshaft eyenziwe ngomgunyathi ene-piston stroke engamamilimitha angu-77.
Ububanzi besilinda sehle baba ngamamilimitha angama-83. Ngakho, injini enamandla 2,5-litre yaba inketho yokugcina. Amakhanda amasilinda emodeli okukhulunywa ngayo afana nalawo asetshenziswa kuyunithi ye-3GR-FSE. I-4GR ifakwe isistimu yokujova uphethiloli eqondile. Injini iye yakhiqizwa kuze kube yilolu suku (ukuqala kokuthengisa kungu-2003).
Okubaluleke kakhulu - imininingwane yobuchwepheshe
Ukujwayelana ne-motor yemodeli okukhulunywa ngayo, akunakwenzeka neze ukudlula izici.

Ubuthakathaka namandla
Izinkinga ezivamile kanye nokuwohloka, kanye nezinzuzo zenjini, kuyathakazelisa kumsebenzisi ongase abe khona hhayi ngaphansi kokucaciswa kobuchwepheshe. Ake siqale ngobubi - cabanga ukuwohloka okuvamile:
- Kungase kube nezinkinga ekuqaliseni injini ebusika obubandayo
- I-throttle ngokushesha igcwala ukungcola, okunomthelela omubi ekungenzini kahle
- Inkinga yokusetshenziswa kukawoyela okuqhubekayo
- Ama-clutch ohlelo lokulawula isigaba se-VVT-i enza umsindo okhencezayo uma uqalisa injini
- Insiza encane yepompo yamanzi kanye nekhoyili yokuthungela
- Kungase kube khona ukuvuza engxenyeni yerabha yomugqa kawoyela.
- Izakhi ze-aluminium zesistimu kaphethiloli zivame ukuqhuma ngesikhathi sokushisela
- Khumbula inkampani ngenxa yemithombo ye-valve yekhwalithi ephansi
Manje kufanelekile ukukhomba izinzuzo nezimfanelo ezikhethekile zenjini:
- Ukwakhiwa okuqinisiwe
- Amandla anyusiwe
- Ubukhulu obuncane kunemodeli yangaphambilini
- Insiza yokusebenza ehlaba umxhwele
- Ukuthembeka
Ukulungiswa kwezinjini zale modeli kuyadingeka njalo ngamakhilomitha ayizinkulungwane ezingu-200 - 250. Ukushintshwa okufika ngesikhathi kanye nekhwalithi ephezulu kukhulisa impilo yemoto ngaphandle kokuphuka okubalulekile kanye nezinkinga eziholela kumshayeli. Kuyathakazelisa ukuthi ukulungisa injini kungenzeka ngezandla zakho, kodwa kungcono ukuphathisa umsebenzi ochwepheshe abanekhono esiteshini sesevisi.
Izimoto ezihlomile
Ekuqaleni, izinjini zemodeli okukhulunywa ngayo zazingavamile ukufakwa ezimotweni, kodwa ngokuhamba kwesikhathi i-4GR-FSE yaqala ukufakwa ezimotweni zohlobo lwaseJapane iToyota. Manje eduze nephuzu - cabangela amamodeli we "Japanese", ngesikhathi esisodwa efakwe le yunithi:
- i-Toyota Crown
- Toyota Mark
- I-Lexus GS250 ne-IS250
Amamodeli ahlukene ezimoto zaseJapane afakwe injini eminyakeni ehlukene. Kuyaphawuleka ukuthi imodeli injini ngokuvamile isetshenziswa ukuhlomisa ezinye crossovers namaloli. Konke sibonga umqondo olula nocabangelayo.
Ukushuna kwenjini
Ukushuna injini yaseJapan engu-4GR-FSE kuvame ukungabi nangqondo. Kuhle ukusho zisuka nje ukuthi ekuqaleni amandla 2,5-litre iyunithi ayidingi imishini kabusha kanye nesengezo ezihlukahlukene. Kodwa-ke, uma kunesifiso esingenakuvinjelwa sokuyenza ibe ngcono, kufanelekile ukuzama. I-Hardware yesimanje ihlanganisa imisebenzi eminingana, okuhlanganisa ukushintshwa kwezingxenye, "ukuskrola" kwama-shafts, njll.
Ukulungisa kabusha injini kuzobiza imali eningi, ngakho-ke ngaphambi kokuba uqale ukulungisa injini, kuhle ucabangele isinqumo sakho. Ukuphela kwesixazululo esinengqondo kungaba ukufaka i-compressor boost ku-motor, okungukuthi, ukuphoqa kwekhwalithi ephezulu. Ngomzamo nokusebenzisa imali eningi, kuzokwazi ukuthola amandla enjini angama-320 hp. nge., ukwandisa amandla namandla, kanye nokwengeza intsha kuyunithi.
Okunye
Intengo yenjini emakethe yasekhaya iqala ku-$ 1, futhi incike esimweni senjini, unyaka wokukhiqiza nokugqoka. Ngokuvakashela amakhasi esayithi ukuze kudayiswe izingxenye zezimoto nezingxenye, ngokuqinisekile uzokwazi ukuthola imoto efanelekile kukhathalogi. Mayelana nokuthi yikuphi uwoyela ongcono ukusebenzisa ukuthuthukisa ukusebenza kwenjini, imibono yabanikazi bezimoto iyahlukahluka. Izibuyekezo ezimayelana nokusebenza kwenjini ezingosini zezihloko zinhle kakhulu. Kodwa kunezimpendulo ezingezinhle, ngokusho ukuthi iyunithi yamandla inezinkinga eziningi.
