Injini yeToyota 2GR-FXS
Okuqukethwe
Isifiso sabakhi bezinjini baseJapan sokuthuthukisa imikhiqizo yabo siholele ekwakhiweni kwemodeli entsha ochungechungeni lwenjini engu-2GR. Injini engu-2GR-FXS yakhelwe ukufakwa ezinguqulweni eziyingxube zezimoto zakwaToyota. Eqinisweni, inguqulo eyi-hybrid ye-2GR-FKS eyakhiwe ngaphambilini.
Incazelo
Injini engu-2GR-FXS yakhelwe iToyota Highlander. Kufakwe kusukela ngo-2016 kuze kube manje. Cishe ngasikhathi sinye, i-American Toyota brand Lexus (RX 450h AL20) yaba ngumnikazi wale moto. Umkhiqizi yiToyota Motor Corporation.
Okuhlukile kulele eqinisweni lokuthi izinjini zalolu chungechunge azizange zifakwe i-turbocharger, futhi uphethiloli kuphela osetshenziswa njengophethiloli. Naphezu kwevolumu emangalisayo (3,5 amalitha), ukusetshenziswa kukaphethiloli emgwaqeni omkhulu kungadluli 5,5 l / 100 km.
I-ICE 2GR-FXS eguquguqukayo, umjovo oxubile, umjikelezo we-Atkinson (ukucindezela okwehlisiwe ku-multifold intake).
I-cylinder block yenziwe nge-aluminium alloy. Okumise okwe-V. Inamasilinda angu-6 anama-cast iron liners. I-pan kawoyela ehlanganisiwe - ingxenye engaphezulu eyenziwe nge-aluminium alloy, ingxenye engezansi - insimbi. Kunesikhala samajethi kawoyela ukuze kuhlinzekwe ukupholisa nokuthambisa amapiston.
Ama-pistons ayi-alloy ekhanyayo. Isiketi siqukethe i-anti-friction coating. Zixhunywe ezintini zokuxhuma ngeminwe entantayo.
I-crankshaft kanye nezinduku zokuxhuma zenziwe ngensimbi enamandla kakhulu ngokufoja.
Ikhanda le-cylinder - i-aluminium. Ama-camshaft afakwe endaweni ehlukile. Idrayivu ye-valve ifakwe izinxephezelo ze-hydraulic valve clearance.
I-manifold yokuthatha i-aluminium.
Idrayivu yesikhathi inezigaba ezimbili, iketango, elinama-hydraulic chain tensioners. Ukugcoba kwenziwa ngama-nozzles akhethekile kawoyela.

Izinkomba zokusebenza
I-motor, ngokusho kokubuyekezwa kwabanikazi, inokwethenjelwa kakhulu, ngaphansi kwezincomo zomkhiqizi ngokusebenza kwayo. Kodwa-ke, kukhona ukungalungi okukhona kulo lonke uchungechunge lwe-2GR:
- ukwanda komsindo wokuhlangana kwe-VVT-I kohlelo lwe-Dual VVT-i;
- ukwanda kokusetshenziswa kukaphethiloli ngemva kwamakhilomitha ayizinkulungwane eziyi-100;
- ukugoba kwama-valve lapho iketango lesikhathi liphukile;
- ukunciphisa isivinini sokungenzi lutho.
Ukwengeza, kukhona ulwazi mayelana nokugotshwa kwama-valve lapho iketango lehliswa ku-VVT-i sprocket. Ukungasebenzi kahle okunjalo kungenzeka lapho ukhulula amabhawodi okulawula isigaba.
Ijubane lokungenzi lutho liba nokungazinzi ngenxa yokungcoliswa kwama-throttle valves. Ukuzihlanza kanye njalo ngemuva kwezinkulungwane ezingama-1 km kuzoyisusa le nkinga.
Amaphuzu abuthakathaka enjini ahlanganisa ipompo yamanzi, iqembu le-cylinder-piston kanye nokuthambekela kokungcolisa ama-throttle valves. Ngokuqondene nepompo yamanzi, kufanele kuqashelwe ukuthi umthombo womsebenzi wawo ungamakhilomitha angama-50-70 ayizinkulungwane zokugijima kwemoto. Kulesi sigaba, ukubhujiswa kwe-seal kwenzeka. Isipholile siqala ukuvuza.
I-CPG idinga ukusetshenziswa kwamafutha ekhwalithi ephezulu. Ukushintsha amabhrendi ashibhile kuholela ekwandeni kokuguga kwamapiston namasilinda. Ama-throttle valves ashiwo ngaphambili.
Ayikho idatha ethile mayelana nokugcinwa ngenxa yesikhathi esifushane sokusebenza kwayo. Ngesikhathi esifanayo, kunezincomo zokushintsha injini ngenjini yenkontileka lapho usebenza isisetshenziswa. Naphezu kwalokhu, ukuba khona kwemikhono ye-cast-iron kudala izimfuneko zokuthi kungenzeka ukuguqulwa okukhulu.
Ngakho, singaphetha ngokuthi: Toyota 2GR-FXS injini inamandla aphezulu, ukwethembeka nokukhuthazela. Kodwa ngesikhathi esifanayo, kudinga ukunamathela ngokuqinile ezincomo zomenzi ngokusebenza kwayo.
Amagama ambalwa mayelana nokushuna
Iyunithi ye-2GR-FXS ingaba namandla nakakhulu uma ishunwa ngokufaka i-turbo kit compressor (TRD, HKS). Ama-pistons ashintshwa ngesikhathi esifanayo (i-Wiseco Piston ye-compression ratio 9) kanye nemibhobho engu-440 cc. Sebenza enkonzweni yemoto ekhethekile usuku olulodwa, futhi amandla enjini azokhula abe ngu-350 hp.
Ezinye izinhlobo zokushuna azisebenzi. Okokuqala, umphumela ongabalulekile womsebenzi (ukulungiswa kwe-chip), futhi okwesibili (ukufakwa kwe-compressor enamandla kakhulu), lokhu kuyizindleko eziphakeme ezingenabulungisa kanye nesizathu sezinkinga zobuchwepheshe ezivamile ngenjini.
Injini ye-Toyota 2GR-FXS ithatha indawo efanelekile kulayini we-2GR kuzo zonke izinkomba eziyinhloko zobuchwepheshe nezomnotho.
Lapho ifakiwe
