2.0 Injini ye-TFSi - okufanele ukwazi ngayo

Iyunithi ikhombisa imiphumela emihle kakhulu, endleleni nangesikhathi somncintiswano. Le ndondo, ekhishwe yi-UKIP Media & Events Automotive Magazine, ingene enjinini esesigabeni se-150 kuya ku-250 HP. Yini okufanele ukwazi ngenjini engu-2.0 TFSi four-cylinder? Hlola!

Yayiyini isici seyunithi yomndeni we-EA113?

Iyunithi ye-2.0 TFSi ingeyomndeni wakwa-EA113 futhi yavela ezimotweni zakwaVolkswagen AG ngo-2004. Yakhiwe ngesisekelo seyunithi ye-VW 2.0 FSi efunwa ngokwemvelo, efakwe umjovo oqondile wamafutha. Ungasho ukuthi ubhekene nenguqulo entsha ngokungeza okuthi "T" kusifinyezo. 

Ukucaciswa kwenjini entsha kanye nokwehluka kwabandulele

Ibhulokhi nayo iqinisiwe. Ngenxa yalokhu, injini engu-2.0 TFSi ikhiqiza amandla amakhulu kakhulu kunenguqulo ye-TFS. Kuyafaneleka ukulandelela izixazululo ezisetshenziswe iphuzu nephuzu.

• Ibhulokhi entsha iphinde isebenzise insimbi ekhonjiwe kune-aluminium cylinder block.
• Ngaphakathi, kukhona ama-balance shafts aphindwe kabili, i-crankshaft enamandla, nama-piston amasha kanye nezinduku zokuxhuma zesilinganiso esiphansi sokucindezela.
• Ikhanda lesilinda elinama-valve angu-16 elinama-camshaft amabili lafakwa phezu kwebhulokhi.
• Isebenzisa futhi ama-camshaft amasha, ama-valve kanye neziphethu zamavalvu eziqinisiwe.
• Ngaphezu kwalokho, injini engu-2.0 TFSi iphinde ibe nesikhathi esishintshayo se-valve ye-camshaft yokudonsa kuphela.
• Ezinye izixazululo zifaka umjovo kaphethiloli oqondile kanye nama-hydraulic tappets.

Abaqambi be-Volkswagen ukukhathazeka baphinde banquma ukusebenzisa i-turbocharger encane ye-BorgWarner K03 (ingcindezi enkulu ye-0,6 bar), ehlinzeka nge-torque ephezulu - kusukela ku-1800 rpm. Ngezinguqulo ezinamandla kakhudlwana, okokusebenza kuhlanganisa ne-turbocharger esebenza kahle kakhulu ye-KKK K04.

2.0 TFSi injini evela eqenjini le-EA888

Ngo-2008, ukukhiqizwa kwe-four-cylinder turbocharged petroli injini ye-VW 2.0 TSI / TFSI yeqembu le-EA888 yethulwa. Idizayini yayo ibisekelwe ekwakhiweni kweyunithi ye-1.8 TSI/TFSI yeqembu le-EA888. Kunezizukulwane ezintathu zeyunithi entsha ye-2.0.

2.0 FSi I block

Lo dizili waziwa ngamakhodi:

• kusihlwa;
• UTSHWALA;
• I-CBFA;
• I-KTTA;
• I-SSTB.

Umklamo wayo uhlanganisa i-cast-iron cylinder block ene-pitch engu-88 mm nobude obungu-220 mm. I-crankshaft yensimbi eyenziwe ngomgunyathi entsha ene-92,8 stroke inikeza ukugudluka okwengeziwe ngobubanzi obufanayo bobhore. Iyunithi futhi inezinduku zokuxhuma ezimfishane ezingu-144mm namapiston ahlukene. Ngenxa yalokho, isilinganiso sokucindezelwa sehlisiwe saba ngu-9,6:1. Iyunithi ye-motor ifakwe ama-shaft ebhalansi amabili ajikelezayo aqhutshwa iketango.

Yiziphi izixazululo ezisetshenziswe kuleli bhulokhi?

Le njini ye-TFSi ine-turbocharger epholile ngamanzi kanye ne-KKK K03 turbocharger ehlanganiswe ne-cast iron exhaust manifold. Ukucindezela kwayo okuphezulu okuphezulu yi-0,6 bar. Izingxenye zokulawula ze-Bosch Motronic Med 15,5 ECU nazo zasetshenziswa. Injini iphinde ifakwe izinzwa ezimbili ze-oxygen ezihambisana nezindinganiso zokukhishwa kwe-Euro 4 ze-CAWB ne-CAWA, kanye ne-ULEV 2. Inguqulo edalelwe imakethe yaseCanada - i-CCTA inezinzwa ze-oxygen ezingu-3 futhi ihambisana nezimo ze-SULEV.

Block 2.0 TFSi II

Ukukhiqizwa kwenjini yesizukulwane sesibili 2.0 TFSi kwaqala ngo-2008. Enye yezinhloso zokudala iyunithi kwakuwukunciphisa ukungqubuzana, kanye nokwandisa ukusebenza kahle uma kuqhathaniswa ne-1.8 TSI GEN 2. Kulokhu, ama-kingpins ancishisiwe esuka ku-58 kuya ku-52 mm. Kuphinde kwasetshenziswa izindandatho zepiston eziqinile, eziqinile kanye namapiston amasha. Abaklami bahlomise iyunithi ngepompo likawoyela elilungisekayo.

Ingabe le njini inayo i-AVS?

I-TFSi ku-Audi nayo inohlelo lwe-AVS (lwe-CCZA, CCZB, CCZC kanye ne-CCZD). Uhlelo lwe-AVS luwuhlelo olunezigaba ezimbili lokulawula i-valve yokungenisa. Ishintsha i-valve lift ngezinyathelo ezimbili: 6,35mm no-10mm ngo-3 rpm. Injini engu-100 EA2.0/888 ithobelana nezindinganiso zokukhishwa kwe-Euro 2 zemodeli ye-CDNC kanye ne-ULEV 5 yemodeli ye-CAEB. Ukukhiqiza kwaphela ngonyaka wesi-2. 

2.0TFSi III ibhulokhi

Inhloso yenjini yesizukulwane sesithathu i-2.0 TFSi bekuwukwenza injini ibe lula futhi isebenze kahle. Ine-cast iron cylinder block enezindonga eziwugqinsi ongu-3 mm. Iphinde ibe ne-crankshaft yensimbi, ama-pistons nezindandatho, kanye nepompo likawoyela kanye nama-balance shafts angasindi. 

Abaklami baphinde basebenzise ikhanda le-aluminium eliklanywe kabusha ngokuphelele elinamavalvu angu-16 e-DOHC elinexhaphozi ehlanganisiwe epholiswe ngamanzi edizayini yeyunithi. Uhlelo lwe-AVS nalo luyasetshenziswa lapha, futhi isikhathi se-valve esiguquguqukayo siyatholakala kuwo womabili ama-camshafts.

Yini eshintshile kuyunithi yezimoto ezinamandla kakhulu?

Lezi zinguquko ziphinde zathinta amayunithi afakwe ezimotweni ezisebenza kahle kakhulu, njenge-Audi Sportback Quattro. Lawa bekungamabhayisikili anekhodi ye-CJX. Basebenzise:

• ukuma okuhlukile kwekhanda le-cylinder;
• i-camshaft yokungenisa ephumelelayo;
• ama-valve amakhulu okukhipha;
• Isilinganiso sokucindezela sehliselwe ku-9,3:1.

Konke lokhu kwahambisana nama-injection asebenza kahle kakhulu kanye nephampu kaphethiloli enomfutho ophezulu. Izinguqulo ezinamandla kakhulu futhi zifaka phakathi i-air-to-air intercooler enkulu.

Izimoto zesizukulwane sesithathu nazo zifakwe iyunithi yokulawula injini ye-electronic ECU Siemens Simos 18.1. Bathobela izindinganiso zokukhishwa kwe-Euro 6 emakethe yaseYurophu.

Injini 2.0 TFSi - ifakwe kuziphi izimoto?

Shayela usuka kwaVolkswagen ungatholakala ezimotweni zeqembu ezifana neVolkswagen Golf, Scirocco, Audi A4, A3, A5 Q5, tt, Seat Sharan, Cupra noma Skoda Octavia noma Superb.

Izinjini ze-TFSi - impikiswano

Ikakhulukazi izinjini zokuqala ze-TSI/TFSI zazinamaphutha edizayini avame ukuholela ekuhlulekeni. Ngokuvamile kwakunezimo lapho kudingeke ukuba kulungiswe kabusha injini. Ukulungisa okunjalo kubiza kakhulu. Ngakho-ke imibono engathandeki mayelana nalezi zinjini. 

Injini engu-2.0 TFSi yakhiqizwa kusukela ngo-2008 futhi ithola impendulo eyakhayo kochwepheshe nabashayeli. Ubufakazi balokhu imiklomelo efana ne-"Engine of the Year" nokuduma kubathengi abathakaselayo izimoto ezinale njini ngokusetshenziswa kancane kukaphethiloli nokuphuka okungajwayelekile.
