Injini yeToyota 8GR-FXS
Okuqukethwe
Injini engu-8GR-FXS ingenye into entsha yabakhi bezinjini baseJapan. Imodeli eyakhiwe yafakwa ekukhiqizweni iyi-analogue ye-2GR-FCS eyaziwa kakhulu.
Incazelo
Iyunithi yamandla yesizukulwane esisha se-8GR-FXS yohlelo longitudinal ibonakala ngomjovo kaphethiloli oxubile we-D-4S, ukusetshenziswa kwesistimu yesikhathi ye-valve eguquguqukayo ye-VVT-iW, kanye nokusebenza komjikelezo we-Atkinson. Ikhishwe kusukela ngo-Okthoba 2017. Umqhele ufakwe kwaToyota kusukela ngo-2018, kwaLexuses - ngonyaka odlule.
I-8GR-FXS iyinjini yesizukulwane sesi-8 ye-V-block enekhanda le-aluminium cylinder, ama-camshaft amabili (umndeni wenjini). F - Isakhiwo sesitimela se-valve ye-DOHC, i-X - i-hybrid yomjikelezo we-Atkinson, i-S - D-4S isistimu yomjovo kaphethiloli ehlanganisiwe.
Uhlelo lomjovo wamafutha nomjovo ohlangene. Ukusetshenziswa kwe-D-4S kunomthelela ekwandeni kwamandla, i-torque, ukonga uphethiloli futhi kunciphisa kakhulu ukukhishwa kwamagesi ayingozi emkhathini. Ngesikhathi esifanayo, kufanele kuqashelwe ukuthi inkimbinkimbi yesistimu yokunikezela uphethiloli ingaba umthombo wezinkinga ezengeziwe.
Umshini we-valve unama-shaft amabili, i-valve engaphezulu.
Isistimu yesikhathi se-valve eguquguqukayo i-electronic, kabili. Ithuthukisa kakhulu ukusebenza. Ubuchwepheshe be-Dual VVT-iW obusetshenzisiwe buqinisekisa ukusebenza kahle kwenjini evuthayo yangaphakathi emithwalweni ephansi neyesikhashana.

Ukwethembeka, ubuthakathaka
Kusesekuseni kakhulu ukwahlulela ngokuqondile ukuthembeka kwenjini evuthayo yangaphakathi engu-8GR-FXS ngenxa yesikhathi esifushane sokusebenza (izibalo zephutha ziyahlaziywa). Kodwa izinkinga zokuqala sezivezwe kancane. Ngokwesiko, amamodeli ochungechunge lwe-GR, indawo ebuthakathaka yiphampu yamanzi. Imisindo engaphandle iyaphawulwa ngesikhathi sokuhlanganisa kwe-VVT-I yohlelo lwe-Dual VVT-iW, amakhoyili okuvutha.
Kukhona ulwazi olulodwa mayelana nomshini wokushisa uwoyela omncane, futhi kusukela ekuqaleni kokusebenza kwenjini. Kodwa kusesekuseni kakhulu ukucabangela zonke izinkinga ezibalwe njengenkinga yeyunithi yamandla, ngoba zingavela ngenxa yamaphutha enziwe umshayeli ngokwakhe ngesikhathi sokusebenza.
Akudingekile ukukhuluma ngokugcinwa kwenjini yangaphakathi yomlilo - umenzi akahlinzeki ngokulungiswa okukhulu kweyunithi. Kodwa ukuba khona kwama-cast-iron liners ku-cylinder block kunikeza ithemba lokuthi kungenzeka.
Mayelana nokushuna
Injini engu-8GR-FXS, njengazo zonke ezinye, ingaphansi kokushunwa. Ngokolwazi olutholakalayo, ukulungiswa kwe-chip kwahlolwa ngokufaka imojuli ye-pedal-box evela kuzinhlelo ze-DTE (DTE PEDALBOX) - eyenziwe eJalimane.
Kumele kukhunjulwe ukuthi lolu hlobo lokulungisa alukhulisi amandla enjini, kodwa lulungisa kuphela izilungiselelo zokulawula injini yefektri. Nakuba, ngokusho kwabanye abanikazi, i-chip tuning empeleni ayinikezi izinguquko eziphawulekayo.
Ayikho idatha kwezinye izinhlobo zokulungisa (umkhathi, ukufakwa kwe-turbo compressor ngokushintshwa kanyekanye kwamapiston), njengoba injini ivele emakethe muva nje.
Amafutha enjini
Umkhiqizi uncoma ukushintsha uwoyela ngemuva kwamakhilomitha ayizinkulungwane eziyi-10 noma kanye ngonyaka. Inketho eyamukeleka kakhulu ukusetshenziswa kokwenziwa kokugcoba kweToyota Motor Oil SN GF-5 5W-30. I-DXG 5W-30 ingasetshenziswa esikhundleni. Lapho ukhetha uwoyela, udinga ukunaka izinga layo lekhwalithi (elikhonjiswe yizimpawu SN). Uma kwenzeka ukwanda kokusetshenziswa ("i-oil burner"), kunconywa ukuthi ushintshele ezinhlobonhlobo ezinokuqina okuqinile - 10W-40. Ngokwesibonelo, Shell Helix 10W-40.
Ukuthengwa kwenjini yenkontileka
Uma kudingekile, ukuze ushintshe, ungakwazi ukuthenga kalula inkontileka ICE 8GR-FXS. Abathengisi kuzo zonke izifunda ze-Russian Federation banikeza izinjini zangempela nganoma iyiphi indlela yokukhokha, inkokhelo yesitolimende efika ezinyangeni eziyi-12.
Ama-ICE wenkontileka alungiselwa ukudayiswa kwangaphambili futhi ahlolelwe ukuhambisana nezindinganiso. Ezimweni eziningi, umdayisi unikeza isiqinisekiso sekhwalithi yezimpahla (imvamisa izinyanga eziyi-6). Ukuze ucacise imigomo yokuthengisa, udinga ukuya kuwebhusayithi yomthengisi futhi ucacise yonke imibuzo onayo.
Isiphetho kuphela ukuthi naphezu kokushiyeka okukhona, i-Toyota idale injini elula, ethembekile, ngesikhathi esifanayo enamandla futhi eyonga.
Lapho ifakiwe
