Jet injini 1.4 t - muyenera kudziwa chiyani?

Popanga m'badwo uwu, Fiat adanena kuti injini ya 1.4 T Jet (monga mayunitsi ena a banja ili) idzagwirizanitsa chikhalidwe chapamwamba cha ntchito ndi kuyendetsa ndalama. Njira yothetsera vutoli inali kuphatikiza kwatsopano kwa turbocharger ndi kukonzekera kosakaniza koyendetsedwa. Kuwonetsa zambiri zofunika kwambiri za 1.4T Jet kuchokera ku Fiat!

Jet injini 1.4 t - zambiri zofunika

Chipangizocho chimapezeka m'mitundu iwiri - chofooka chili ndi mphamvu ya 120 hp, ndipo champhamvu chimakhala ndi 150 hp. Zitsanzo zopangidwa ndi okonza Fiat Powertrain Technologies ali ndi mapangidwe opangidwa ndi injini ina yodziwika bwino - 1.4 16V Moto. Komabe, adasinthidwanso chifukwa chofuna kukhazikitsa turbo.

Injini ya 1.4 T imasiyanitsidwa ndi mfundo yakuti imapereka mphamvu zokwanira komanso nthawi yomweyo kugwiritsa ntchito mafuta. Ilinso ndi mawonekedwe osiyanasiyana osinthika komanso mayankho abwino kwambiri osinthira zida. 

Fiat unit technical data

Injini ya 1.4 T Jet ndi injini ya DOHC yokhala ndi ma valve 4 pa silinda imodzi. Zida za unit zimaphatikizapo magetsi, jekeseni wamafuta ambiri, komanso turbocharging. Injiniyo idatulutsidwa mu 2007 ndipo idapereka mphamvu zokwanira 9: 105, 120, 135, 140 (Abarth 500C), 150, 155, 160, 180 ndi 200 hp. (Abarth 500 Assetto Corse). 

Injini ya 1.4 t jet ili ndi lamba woyendetsa ndi jekeseni wamafuta osalunjika. Tikumbukenso kuti unit alibe zinthu zambiri zovuta structural - kupatula turbocharger, zomwe zimapangitsa kukhala zosavuta kusamalira. 

Makhalidwe a mapangidwe a injini ya jet matani 1.4.

Pankhani ya 1.4 T Jet, chipika cha silinda chimapangidwa ndi chitsulo chosungunuka ndipo chimakhala ndi mphamvu zamakina kwambiri. Mbali yapansi ya crankcase imapangidwa ndi alloy-cast aluminium alloy ndipo ndi gawo lazonyamula katundu pamodzi ndi crankcase yayikulu. 

Imayamwa katundu wopangidwa ndi crankshaft ndikupanganso membala wokhazikika wokhala ndi bokosi la gear kudzera pamkono wamachitidwe. Imagwiranso ntchito yokonza kunyamula kwa shaft yamanja ya axle. Injini ya 1.4 T ilinso ndi crankshaft yachitsulo yazitsulo zisanu ndi zitatu, cholumikizira cholimba cholimba ndi ma bere asanu.

Kuphatikiza kwa turbocharger ndi intercooler ndi valavu yodutsa - kusiyana ndi mtundu wa aggregate

Kuphatikiza uku kwapangidwa mwapadera pazotulutsa ziwiri za injini ya 1.4 T-Jet. Komabe, pali kusiyana kwina pakati pa mitundu iyi. Kodi ndi chiyani? 

1. Kwa injini yamphamvu kwambiri, turbine wheel geometry imatsimikizira kupanikizika kwakukulu pama torque apamwamba kwambiri. Chifukwa cha izi, mphamvu zonse za unit zitha kugwiritsidwa ntchito. 
2. Momwemonso, mumtundu wamphamvu kwambiri, kupanikizika kumawonjezeka kwambiri chifukwa cha kuwonjezereka, komwe kumawonjezera makokedwe kufika pa 230 Nm ndi wategate watsekedwa. Pachifukwa ichi, machitidwe a magulu amasewera ndi ochititsa chidwi kwambiri.

Kugwiritsa Ntchito Magawo - Mavuto Odziwika

Chimodzi mwazinthu zolakwika kwambiri za injini ya 1.4 T Jet ndi turbocharger. Vuto lofala kwambiri ndi vuto losweka. Izi zimawonetseredwa ndi mluzu, utsi wochokera ku utsi ndi kuchepa kwa mphamvu pang'onopang'ono. Ndizofunikira kudziwa kuti izi zimagwira ntchito ku mayunitsi a turbine a IHI - okhala ndi zida za Garrett, sizolakwika.

Mavuto amasokonekera amaphatikizanso kutayika kwa zoziziritsa kukhosi. Kusagwira bwino ntchito kumatha kuzindikirika pamene mawanga akuwonekera pansi pagalimoto. Palinso malfunctions kugwirizana ndi kutayikira kwa injini mafuta - chifukwa kungakhale kulephera kwa bobbin kapena sensa. 

Momwe mungathanirane ndi zovuta za injini ya 1.4 T-Jet?

Kuti muthane ndi moyo waufupi wa turbocharger, njira yabwino ndikusinthira mabawuti amafuta ndi turbine yamafuta. Izi ndichifukwa choti mkati mwa chinthuchi muli fyuluta yaying'ono yomwe imachepetsa kuyatsa kwa rotor ngati kutayika kwamphamvu. Komabe, pakakhala zovuta ndi heatsink, ndi bwino kusintha gawo lonselo. 

Ngakhale pali zolakwika zina, injini ya 1.4 T jet imatha kuyesedwa ngati yogwira ntchito bwino. Palibe kusowa kwa zida zosinthira, zitha kukhala zogwirizana ndi unsembe wa LPG ndipo zimapereka magwiridwe antchito abwino - mwachitsanzo, pankhani ya Fiat Bravo, ndi masekondi 7 mpaka 10 mpaka 100 km / h.

Panthawi imodzimodziyo, ndizochepa kwambiri - pafupifupi malita 7/9 pa 100 km. Utumiki wanthawi zonse, ngakhale lamba wanthawi zonse pamakilomita 120 aliwonse. Km, kapena flywheel yoyandama pamtunda uliwonse wa 150-200 km iliyonse, iyenera kukhala yokwanira kutenga mwayi pa 1,4-t jet unit kwa nthawi yayitali ndikujambula mtunda wautali.
