2.0 TFSi injini - zomwe muyenera kudziwa za izo

Chigawochi chikuwonetsa zotsatira zabwino kwambiri, pamsewu komanso panthawi ya mpikisano. Mphothoyi, yoperekedwa ndi UKIP Media & Events Automotive Magazine, idapita ku injini m'gulu la 150 mpaka 250 HP. Kodi muyenera kudziwa chiyani za injini ya 2.0 TFSi four-cylinder? Onani!

Kodi gawo lochokera kubanja la EA113 linali lotani?

Gawo la 2.0 TFSi ndi la banja la EA113 ndipo lidawonekera m'magalimoto a Volkswagen AG mu 2004. Idapangidwa pamaziko a gawo lachilengedwe la VW 2.0 FSi, lomwe linali ndi jakisoni wamafuta mwachindunji. Mutha kudziwa kuti mukugwiritsa ntchito mtundu watsopano powonjezera "T" mu chidule chake. 

Kufotokozera kwa injini yatsopano ndi kusiyana kwake ndi omwe adatsogolera

Chidacho chalimbikitsidwanso. Chifukwa cha izi, injini ya 2.0 TFSi imapanga mphamvu zambiri kuposa mtundu wa TFS. Ndikoyenera kutsata mayankho omwe agwiritsidwa ntchito mfundo ndi mfundo.

• Chida chatsopanochi chimagwiritsanso ntchito chitsulo chonyezimira osati chotchinga cha aluminiyamu ya silinda.
• Mkati mwake, muli ma shafts awiri, crankshaft yolimba, ndi ma pistoni atsopano ndi ndodo zolumikizira kuti muchepetse kupsinjika.
• Mutu wa silinda wa 16 wokhala ndi ma camshaft awiri unayikidwa pamwamba pa chipikacho.
• Imagwiritsanso ntchito ma camshafts atsopano, ma valve ndi akasupe a valve olimbikitsidwa.
• Kuphatikiza apo, injini ya 2.0 TFSi imakhalanso ndi nthawi yosinthika ya valve ya camshaft yolowera yokha.
• Njira zina ndi monga jekeseni wamafuta mwachindunji ndi matepi a hydraulic.

Okonza Volkswagen nkhawa anaganizanso ntchito yaing'ono BorgWarner K03 turbocharger (kuthamanga pazipita mipiringidzo 0,6), amene amapereka makokedwe mkulu - kuchokera 1800 rpm. Kwa mitundu yamphamvu kwambiri, zidazo zimaphatikizansopo turbocharger ya KKK K04 yapamwamba kwambiri.

2.0 TFSi injini kuchokera ku gulu la EA888

Mu 2008, kupanga anayi yamphamvu turbocharged petulo injini VW 2.0 TSI / TFSI gulu EA888 anapezerapo. Mapangidwe ake adatengera kapangidwe ka 1.8 TSI/TFSI gulu la EA888. Pali mibadwo itatu ya gawo latsopano la 2.0.

2.0 FSi I unit

Dizilo iyi imadziwika ndi ma code:

• MADZULO;
• MOWA;
• CBFA;
• KTTA;
• Mtengo wa STB.

Mapangidwe ake akuphatikizapo chipika chachitsulo chachitsulo chokhala ndi phula la 88 mm ndi kutalika kwa 220 mm. New forged steel crankshaft yokhala ndi sitiroko ya 92,8 imapereka kusamutsidwa kochulukirapo m'mimba mwake momwemo. Chipangizocho chilinso ndi ndodo zolumikizira zazifupi za 144mm ndi ma pistoni osiyanasiyana. Zotsatira zake, chiŵerengero cha kuponderezana chinachepetsedwa kukhala 9,6: 1. Chigawo chagalimotocho chimakhala ndi ma shaft awiri ozungulira ozungulira omwe amayendetsedwa ndi unyolo.

Ndi mayankho ati omwe adagwiritsidwa ntchito mu block iyi?

Injini ya TFSi iyi ili ndi turbocharger yoziziritsidwa ndi madzi ndi turbocharger ya KKK K03 yophatikizidwa muzambiri zotulutsa chitsulo. Kuthamanga kwake kwakukulu ndi 0,6 bar. Zida zowongolera za Bosch Motronic Med 15,5 ECU zidagwiritsidwanso ntchito. Injiniyo ilinso ndi masensa awiri a okosijeni omwe amatsatira miyezo ya Euro 4 emissions ya CAWB ndi CAWA, komanso ULEV 2. Baibulo lomwe linapangidwira msika wa Canada - CCTA ili ndi 3 mpweya wa okosijeni ndipo imagwirizana ndi SULEV.

Block 2.0 TFSi II

Kupanga m'badwo wachiwiri 2.0 TFSi injini anayambanso mu 2008. Chimodzi mwa zolinga zopanga unit chinali kuchepetsa kukangana, komanso kuwonjezera mphamvu poyerekeza ndi 1.8 TSI GEN 2. Pachifukwa ichi, mafumuwo adachepetsedwa kuchokera ku 58 mpaka 52 mm. Mphete za pistoni zoonda, zocheperako komanso ma pistoni atsopano zidagwiritsidwanso ntchito. Okonzawo adayika makinawo ndi pompa mafuta osinthika.

Kodi injini iyi ili ndi AVS?

TFSi ku Audi ilinso ndi AVS system (ya CCZA, CCZB, CCZC ndi CCZD). Dongosolo la AVS ndi njira yowongolera ma valve yonyamula magawo awiri. Imasintha kukweza kwa valve mu magawo awiri: 6,35 mm ndi 10 mm pa 3 rpm. Injini ya 100 EA2.0/888 imagwirizana ndi miyezo ya Euro 2 emission ya CDNC model ndi ULEV 5 ya mtundu wa CAEB. Kupanga kunatha mchaka 2. 

2.0TFSi III block

Cholinga cha injini ya 2.0 TFSi ya m'badwo wachitatu chinali kupanga injini yopepuka komanso yothandiza kwambiri. Ili ndi chipika chachitsulo chachitsulo chokhala ndi makoma a 3 mm wandiweyani. Ilinso ndi crankshaft yachitsulo, ma pistoni ndi mphete, komanso pampu yamafuta ndi ma shafts opepuka. 

Okonzawo adagwiritsanso ntchito mutu wa aluminiyamu wa 16-valve wa DOHC wokhala ndi makina ophatikizika oziziritsidwa ndi madzi pamapangidwe a unit. Dongosolo la AVS likugwiritsidwanso ntchito pano, ndipo nthawi yosinthira ma valve ikupezeka pama camshaft onse.

Kodi chasintha ndi chiyani mugawo la magalimoto amphamvu kwambiri?

Zosinthazi zidakhudzanso magawo omwe adayikidwa pamagalimoto ochita bwino kwambiri, monga Audi Sportback Quattro. Awa anali njinga okhala ndi code ya CJX. Iwo ankagwiritsa ntchito:

• mawonekedwe osiyana a mutu wa silinda;
• camshaft yoyenera kudya;
• valavu zazikulu zotulutsa mpweya;
• Chiŵerengero cha kuponderezana chachepetsedwa kukhala 9,3: 1.

Zonsezi zidathandizidwa ndi majekeseni owonjezera komanso pampu yamafuta othamanga kwambiri. Mabaibulo amphamvu kwambiri amakhalanso ndi choziziritsa kukhosi chokulirapo cha air-to-air.

Ma motors a m'badwo wachitatu alinso ndi zida zamagetsi zamagetsi zamagetsi ECU Siemens Simos 18.1. Amatsatira miyezo yotulutsa Euro 6 pamsika waku Europe.

Engine 2.0 TFSi - ndi magalimoto ati omwe adayikidwa?

Yendetsani kuchokera ku Volkswagen mutha kupezeka m'magalimoto agululi monga Volkswagen Golf, Scirocco, Audi A4, A3, A5 Q5, tt, Seat Sharan, Cupra kapena Skoda Octavia kapena Superb.

Injini za TFSi - kutsutsana

Makamaka injini zoyamba za TSI / TFSI zinali ndi zolakwika zamapangidwe zomwe nthawi zambiri zimabweretsa kulephera. Nthawi zambiri panali ngakhale zinthu pamene kukonzanso kwakukulu kwa injini kunakhala kofunika. Kukonza koteroko kumakwera mtengo kwambiri. Chifukwa chake malingaliro olakwika okhudza injini izi. 

Injini ya 2.0 TFSi idapangidwa kuyambira 2008 ndipo imalandira ndemanga zabwino kuchokera kwa akatswiri ndi madalaivala. Umboni wa izi ndi mphoto monga "Engine of the Year" ndi kutchuka kwa ogula omwe amayamikira magalimoto ndi injini iyi chifukwa cha mafuta otsika komanso kuwonongeka kosowa.
