Toyota 2GR-FXS injini
Zamkatimu
Chikhumbo cha omanga injini za ku Japan kuti apititse patsogolo malonda awo chapangitsa kuti pakhale mtundu watsopano mu mzere wa injini wa 2GR. Injini ya 2GR-FXS idapangidwa kuti iziyika m'magalimoto osakanizidwa amtundu wa Toyota. M'malo mwake, ndi mtundu wosakanizidwa wa 2GR-FKS yomwe idapangidwa kale.
mafotokozedwe
Injini ya 2GR-FXS idapangidwira Toyota Highlander. Adakhazikitsidwa kuyambira 2016 mpaka pano. Pafupifupi nthawi imodzi, American Toyota mtundu Lexus (RX 450h AL20) anakhala mwini galimoto. Wopanga ndi Toyota Motor Corporation.
Kusiyanitsa kuli chifukwa chakuti injini za mndandandawu sizinali ndi turbocharger, ndipo mafuta okhawo amagwiritsidwa ntchito ngati mafuta. Ngakhale voliyumu chidwi (3,5 malita), mafuta pa msewu si upambana 5,5 L / 100 Km.
ICE 2GR-FXS transverse, jekeseni wosakanikirana, kuzungulira kwa Atkinson (kuchepetsa kupanikizika muzinthu zambiri).
Silinda ya silinda imapangidwa ndi aluminiyamu alloy. Wooneka ngati V. Ili ndi masilinda 6 okhala ndi zitsulo zotayira. Chiwaya chophatikizika chamafuta - chapamwamba chopangidwa ndi aluminium alloy, m'munsi - chitsulo. Pali malo opangira ma jets opangira mafuta kuti aziziziritsa komanso kuthirira ma pistoni.
Ma pistoni ndi aloyi wopepuka. Siketiyo imakhala ndi anti-friction coating. Amalumikizidwa ndi ndodo zolumikizira ndi zala zoyandama.
Crankshaft ndi ndodo zolumikizira zimapangidwa ndi chitsulo champhamvu kwambiri popanga.
Mutu wa Cylinder - aluminium. Ma camshafts amaikidwa m'nyumba yosiyana. Ma valve oyendetsa amakhala ndi ma hydraulic valve clearance compensators.
Zomwe zimapangidwira ndi aluminiyumu.
Kuyendetsa nthawi kumakhala ndi magawo awiri, unyolo, wokhala ndi ma hydraulic chain tensioners. Lubrication ikuchitika ndi mafuta nozzles wapadera.

Zizindikiro za magwiridwe antchito
Galimoto, malinga ndi ndemanga za eni ake, ndiyodalirika kwambiri, malinga ndi malangizo a wopanga ntchito yake. Komabe, pali zovuta zomwe zimachitika pamndandanda wonse wa 2GR:
- kuwonjezereka kwa phokoso la VVT-I couplings ya Dual VVT-i system;
- kuchuluka kwa mafuta pambuyo pa makilomita 100 zikwi;
- kupindika kwa ma valve pamene unyolo wanthawi wathyoka;
- kuchepetsa liwiro lopanda ntchito.
Kuonjezera apo, pali zambiri zokhudzana ndi kupindika kwa ma valve pamene unyolo watsitsidwa kuchokera ku VVT-i sprocket. Kuwonongeka kotereku kumatheka mukamasula mabawuti owongolera gawo.
Kuthamanga kosagwira ntchito kumakhala kosakhazikika chifukwa cha kuipitsidwa kwa ma throttle valves. Kuwayeretsa kamodzi pa makilomita zikwi 1 kudzathetsa vutoli.
Zofooka zamagalimoto zimaphatikizapo mpope wamadzi, gulu la cylinder-piston komanso chizolowezi choipitsa ma throttle valves. Ponena za mpope wamadzi, tisaiwale kuti gwero la ntchito yake ndi 50-70 zikwi zikwi za galimoto. Pa gawo ili, kuwonongeka kwa chisindikizo kumachitika. Kuzizira kumayamba kutayikira.
CPG imafuna kugwiritsa ntchito mafuta apamwamba kwambiri. Kusintha ndi mitundu yotsika mtengo kumabweretsa kuwonjezereka kwa ma pistoni ndi masilindala. Ma valve a Throttle adatchulidwa kale.
Palibe deta yeniyeni yosamalira bwino chifukwa cha nthawi yochepa ya ntchito yake. Pa nthawi yomweyo, pali malangizo m'malo injini ndi injini mgwirizano pamene ntchito gwero. Ngakhale zili choncho, kukhalapo kwa manja achitsulo kumapanga zofunikira kuti athe kukonzanso kwakukulu.
Choncho, tinganene kuti: "Toyota 2GR-FXS" injini ali ndi mphamvu, kudalirika ndi kupirira. Koma nthawi yomweyo, pamafunika kutsatira mosamalitsa malangizo a wopanga ntchito yake.
Mawu ochepa okhudza kukonza
Gawo la 2GR-FXS litha kukhala lamphamvu kwambiri ngati litakonzedwa ndikuyika turbo kit compressor (TRD, HKS). Ma pistoni amasinthidwa nthawi yomweyo (Wiseco Piston kwa psinjika chiŵerengero 9) ndi nozzles 440 cc. Gwirani ntchito pagalimoto yapadera kwa tsiku limodzi, ndipo mphamvu ya injini idzawonjezeka mpaka 350 hp.
Kukonza kwamitundu ina ndi kosatheka. Choyamba, zotsatira zochepa za ntchito (chip ikukonzekera), ndipo kachiwiri (unsembe wa kompresa wamphamvu kwambiri), ndi zopanda chilungamo mtengo wapamwamba ndi chifukwa cha mavuto pafupipafupi luso injini.
Injini ya Toyota 2GR-FXS ili ndi malo oyenera mu mzere wa 2GR muzowonetsa zonse zazikulu zaukadaulo ndi zachuma.
