2.0 TFSi injini - izvo zvaunofanira kuziva nezvazvo

Iyo unit inoratidza mhedzisiro yakanakisa, munzira uye panguva yemakwikwi. Mubairo, wakapihwa neUKIP Media & Events Automotive Magazine, wakaenda kune injini muchikamu che150 kusvika 250 HP. Chii chakakosha kuziva nezve 2.0 TFSi ina-cylinder injini? Check!

Chii chaive chimiro chechikamu kubva kumhuri yeEA113?

Iyo 2.0 TFSi unit ndeyemhuri yeEA113 uye yakaonekwa muVolkswagen AG mota muna 2004. Yakagadzirwa pahwaro hweiyo yakasikwa inoshuvira VW 2.0 FSi unit, iyo yaive neyakagadzirirwa jekiseni remafuta. Unogona kukuudza kuti uri kubata neshanduro itsva nekuwedzera "T" muchidimbu. 

Tsanangudzo yeinjini nyowani uye misiyano kubva kune vakaitangira

Iyo block yakasimbiswa zvakare. Nekuda kweizvi, injini ye2.0 TFSi inogadzira simba rakawanda kupfuura iro TFS vhezheni. Zvakakodzera kutsvaga mhinduro dzakashandiswa point by point.

• Iyo nyowani nyowani inoshandisawo simbi yakakandwa kwete yealuminium cylinder block.
• Mukati, mune kaviri chiyero shafts, yakasimba crankshaft, uye ese-nyowani mapistoni uye ekubatanidza tsvimbo kune yakaderera compression reshiyo.
• Musoro we 16-valve cylinder une macamshaft maviri wakaiswa pamusoro peblock.
• Iyo inoshandisawo nyowani camshafts, mavharuvhu uye yakasimbiswa mavharuvhu zvitubu.
• Uye zvakare, iyo 2.0 TFSi injini zvakare ine shanduko yevhavha nguva yekutora camshaft chete.
• Dzimwe mhinduro dzinosanganisira yakananga mafuta jekiseni uye hydraulic tappets.

Vagadziri veVolkswagen kunetsekana vakasarudzawo kushandisa diki BorgWarner K03 turbocharger (yakanyanya kudzvinyirira ye0,6 bar), iyo inopa yakakwira torque - kubva 1800 rpm. Kune mamwe mavhezheni ane simba, zvishandiso zvakare zvinosanganisira yepamusoro-inoshanda KKK K04 turbocharger.

2.0 TFSi injini kubva kuEA888 boka

Muna 2008, kugadzirwa kwechina-cylinder turbocharged peturu injini VW 2.0 TSI / TFSI yeboka reEA888 yakatangwa. Dhizaini yayo yaive yakavakirwa pakuvaka kweiyo 1.8 TSI/TFSI unit yeEA888 boka. Kune zvizvarwa zvitatu zveiyo itsva 2.0 unit.

2.0 FSi I unit

Iyi dhiziri inozivikanwa nemakodhi:

• MANHERU;
• DORO;
• CBFA;
• KTTA;
• STB.

Magadzirirwo ayo anosanganisira cast-iron cylinder block ine pitch ye88 mm uye kureba kwe220 mm. New forged simbi crankshaft ine 92,8 sitiroko inopa kumwe kutamiswa kweiyo dhayamita imwechete. Iyo unit zvakare ine 144mm mapfupi ekubatanidza tsvimbo uye akasiyana piston. Nekuda kweizvozvo, iyo compression ratio yakaderedzwa kusvika 9,6: 1. Iyo mota unit inoshongedzerwa neaviri anopokana-anotenderera chiyero shaft inofambiswa neketani.

Ndedzipi mhinduro dzakashandiswa mubhuroko rino?

Iyi injini yeTFSi ine turbocharger yakanyoroveswa nemvura uye KKK K03 turbocharger yakabatanidzwa musimbi yakakandwa inopedza simba. Yayo yakanyanya kukwirisa kumanikidza ndeye 0,6 bar. Bosch Motronic Med 15,5 ECU control zvikamu zvakashandiswa zvakare. Injini inogadzirwawo nemasikirini maviri eokisijeni anoenderana neEuro 4 emissions mitemo yeCAWB neCAWA, pamwe neULEV 2. Shanduro yakasikwa kumusika weCanada - CCTA ine 3 oxygen sensors uye inoenderana neSULEV mamiriro.

Block 2.0 TFSi II

Kugadzirwa kwechizvarwa chechipiri 2.0 TFSi injini yakatangawo muna 2008. Chimwe chezvinangwa zvekugadzira chikwata chaiva kuderedza kupesana, pamwe nekuwedzera kushanda zvakanaka kuenzaniswa ne1.8 TSI GEN 2. Nokuda kweizvi, madzimambo akaderedzwa kubva ku58 kusvika ku52 mm. Mhete dzepiston dzakatetepa, dzakaderera uye mapiston matsva zvakashandiswa zvakare. Vagadziri vakashongedza chikwata nepombi yemafuta inogadziriswa.

Injini iyi ine AVS?

TFSi muAudi zvakare ine AVS system (yeCCZA, CCZB, CCZC uye CCZD). Iyo AVS sisitimu ndeye maviri-nhanho yekutora valve yekusimudza control system. Inoshandura kusimudza kwevhavha mumatanho maviri: 6,35 mm uye 10 mm pa 3 rpm. Injini ye100 EA2.0/888 inowirirana neEuro 2 emission standards yeCDNC modhi uye ULEV 5 ye CAEB modhi. Kugadzirwa kwakapera mugore rechipiri. 

2.0TFSi III block

Chinangwa chechizvarwa chechitatu 2.0 TFSi injini yaive yekuita kuti injini ireruke uye ishande zvakanyanya. Iine simbi yakakandwa cylinder block ine 3 mm gobvu madziro. Iyo ine zvakare simbi crankshaft, piston uye mhete, pamwe nepombi yemafuta uye lightweight bharanzi shafts. 

Vagadziri vakashandisa zvakare yakanyatsogadziridzwa 16-vharuvhu DOHC aruminiyamu musoro ine yakasanganiswa mvura-yakatonhorera exhaust manifold mukugadzira kweyuniti. Iyo AVS sisitimu inoshandiswawo pano, uye inochinja nguva yevharuvhu inowanikwa kune ese ari maviri camshafts.

Chii chachinja muyuniti kune mota dzine simba rakawanda?

Shanduko idzi dzakakanganisawo mayunitsi akaiswa pamotokari dzinoshanda zvakanyanya, senge Audi Sportback Quattro. Aya aive mabhasikoro ane CJX kodhi. Vakashandisa:

• chimiro chakasiyana chemusoro wecylinder;
• inokwanisa kutora camshaft;
• mavharuvhu makuru ekubudisa;
• The compression reshiyo yakaderedzwa kusvika 9,3:1.

Zvese izvi zvaiwedzerwa nemajekiseni anoshanda zvakanyanya uye yakanyanya kudzvanywa mafuta pombi. Mamwe mavhezheni ane simba zvakare ane hombe yemhepo-kune-mhepo intercooler.

Mota dzechizvarwa chechitatu dzakashongedzerwawo neyemagetsi injini yekudzora unit ECU Siemens Simos 18.1. Ivo vanotevedzera Euro 6 emission zviyero zvemusika weEurope.

Injini 2.0 TFSi - yakaiswa mumotokari dzipi?

TFSi injini - kukakavara

Kunyanya yekutanga TSI / TFSI injini dzaive nedhizaini zvikanganiso izvo zvaiwanzo tungamira mukukundikana. Kazhinji paitove nemamiriro ezvinhu apo kugadziridzwa kukuru kweinjini kwakave kuri madikanwa. Kugadzirisa kwakadaro kunodhura zvikuru. Saka maonero asina kunaka pamusoro peinjini idzi. 

Injini ye2.0 TFSi yakagadzirwa kubvira 2008 uye inogamuchira mhinduro yakanaka kubva kune nyanzvi nevatyairi. Uchapupu hweizvi mibayiro yakadai se "Engine of the Year" uye mukurumbira pakati pevatengi vanokoshesa motokari nejini iyi nekuda kwekushandiswa kwemafuta uye kuparara kusingawanzoitiki.
