1.4 Injini ye-TDi VW - konke odinga ukukwazi endaweni eyodwa!

Injini engu-1.4 TDi ifakwe ezimotweni zakwaVolkswagen, Audi, Skoda neSeat, i.e. bonke abakhiqizi beqembu le-VW. Idizili enomjovo kaphethiloli oqondile yayibonakala ngomnotho omuhle, kodwa kwakukhona namazwi ahlobene nokukhubazeka okubuhlungu, isibonelo, ukudlidliza okuqinile noma izinkinga ngokulungisa i-crankcase ye-aluminium. Uma ufuna ukwazi okwengeziwe nge-1.4 TDi, sikumema ukuthi ufunde yonke indatshana.

Umndeni wenjini ye-TDi yakwaVolkswagen - ulwazi oluyisisekelo

Isici esiphawulekayo ukusetshenziswa kobuchwepheshe be-Turbocharged Direct Injection. Izinjini zikadizili ezineTurbocharged nazo zifakwe i-intercooler. Kuyaphawuleka ukuthi Volkswagen iwafaka hhayi kuphela ezimotweni, kodwa futhi Volkswagen Marine izikebhe, kanye Volkswagen Industrial Motor amayunithi.

Injini yokuqala ye-TDi bekuyinjini enamasilinda amahlanu eyethulwa ngo-1989 ne-Audi 100 TDi sedan. Lesi sikhungo senziwe sakamuva ngo-1999. Abasiki bengqephu banezele kuyo iCommon Rail fuel injection system. Kwaba njalo ngenjini ye-V8, eyafakwa ku-Audi A8 3.3 TDi Quattro. Kuyathakazelisa ukuthi injini ye-TDi iphinde yasetshenziswa ezimotweni zomjaho esigabeni se-LMP1.

Inhlanganisela yobuchwepheshe obubili - umjovo oqondile kanye ne-turbocharging

Esimweni sokuqala, uhlelo lokujova uphethiloli lufafaza uphethiloli wedizili ngqo emakamelweni amakhulu avuthayo. Ngakho-ke, inqubo yokushisa egcwele kakhulu iyenzeka kune-prechamber, okuthiwa. umjovo oqondile, okwandisa i-torque futhi unciphise ukukhishwa kwe-exhaust. 

I-turbine eqhutshwa yi-exhaust, yona, icindezela umoya owukhiphayo futhi ikhuphule amandla kanye ne-torque kuyunithi ehlangene, ehamba kancane. Ngaphezu kwalokho, izinjini ze-TDi zifakwe i-intercooler ukunciphisa izinga lokushisa nokwandisa ukuminyana komoya ocindezelwe ngaphambi kokuba ungene kusilinda.

I-TDi yitemu lokumaketha.

Isetshenziswa izinkampani zakwaVolkswagen Group, kanye neLand Rover. Ngaphezu kwegama le-TDi, iVolkswagen iphinde isebenzisa i-SDi - Suction Diesel Injection kumamodeli angewona ama-turbo afiselekayo ngokwemvelo anomjovo oqondile kaphethiloli.

1.4 Injini ye-TDi - ulwazi oluyisisekelo

Le yunithi yamasilinda amathathu, eyasungulwa ngo-2014 ukuze ithathe indawo yemodeli engu-1,2 litre emndenini we-EA189, nayo yasetshenziswa esikhundleni se-four-cylinder 1,6 TDi. Ngokuthakazelisayo, uphiko oluncane lwasebenzisa izingxenye ezithile zenjini enamasilinda amane abuyiselwa ohlelweni lwamasilinda amathathu.

Injini engu-1.4 TDi yathuthukiswa njengomsebenzi wokwehlisa izinga. Esinye sezinyathelo kwakuwukunciphisa isisindo se-crankcase nezinhlangothi zesilinda, lezi zakhi zenziwe nge-ALSiCu3 alloy etholwe ngokusakazwa kwamandla adonsela phansi. Lokhu kuholele ekutheni isisindo senjini sehle ngo-11 kg uma kuqhathaniswa nenjini yangaphambili engu-1,2l TDi kanye no-27 kg yelula kune-1,6l TDi.

Injini engu-1.4 TDi yafakwa kuziphi izinhlobo zezimoto?

Idrayivu evela emndenini we-EA288 yafakwa ezimotweni ezinjengalezi:

• I-Audi: A1;
• Indawo: Ibiza, Toledo;
• Skoda: Fabia III, Rapid;
• IVolkswagen: Polo V.

Izixazululo zokuklama ezivela konjiniyela bakwaVolkswagen

I-power unit ibifakwe i-balance shaft ebishayelwa ngu-gearbox oyi-1:1 single speed obheke ngaku-crankshaft. I-piston stroke nayo inyuswe yaba ngu-95,5 mm, okuvumela ukufuduka okukhulu.

Ezinye izici zokuklama zihlanganisa ama-valve amane isilinda, ama-camshaft amabili e-DOHC, kanye nokusetshenziswa komklamo ofanayo wekhanda lesilinda elitholakala ezinjinini ze-MDB ezine-cylinder. Okunye okukhethiwe kwaba ukupholisa amanzi, i-intercooler, isiguquli se-catalytic, isistimu ye-DPF, ukujikelezwa kabusha kwegesi ekhishwa yiziyingi ezimbili enengcindezi ephansi nephezulu EGR, kanye nesistimu yomjovo ye-DFS 1.20 evela kumkhiqizi iDelphi.

Idatha yobuchwepheshe - ukucaciswa kwenjini 1.4 TDi

Injini engu-1.4 TDi isebenzisa i-aluminium cylinder block kanye nesilinda. Iwudizili ojwayelekile kajantshi, imigqa emi-4, ukucushwa kwamasilinda amathathu namavalvu amane isilinda kusikimu se-DOHC. Amasilinda ngesithuthuthu abe ububanzi 79,5 mm, futhi unhlangothi piston ifinyelela 95,5 mm. Ingqikithi yomthamo wenjini ingu-1422 cu. cm, futhi isilinganiso sokucindezelwa ngu-16,1:1.

Itholakala ngamamodeli angu-75 HP, angu-90 HP. kanye 104hp Ukuze usebenzise kahle injini, i-VW 507.00 ne-5W-30 amafutha ayadingeka. Ngokulandelayo, umthamo wethangi lale nto ungama-3,8 amalitha. Kufanele ishintshwe njalo ngo-20 XNUMX. km.

Ukusebenza kweDrayivu - yiziphi izinkinga?

Uma usebenzisa injini engu-1.4 TDi, kungase kube nezinkinga ngepompo yomjovo. Ukungasebenzi kahle ezibizayo kuqala ngemuva kokugijima cishe kuka-200 km. km. Amasongo okugcina nawo anephutha. Ama-bushings agqoka ngokushesha futhi afakwe ohlwini njengenye yezinto ezibuthakathaka kakhulu zomhlangano wedrayivu. Ngenxa yabo, kwakhiwa umdlalo we-axial owedlulele we-crankshaft.

Izihlungi ze-DPF nazo zivaliwe, okubangele izinkinga eziningi ezimotweni ezinamamayela aphansi. Ezinye izingxenye ezidinga ukunakwa okukhethekile zihlanganisa: ama-injection enjini, ama-flow metres kanye ne-turbocharger. Naphezu kokuthi lolu phiko selunesikhathi eside lusemakethe, ukulungiswa komuntu ngamunye kungaholela ezindlekweni ezinkulu. 

Ingabe i-1.4 TDi iyisinqumo esihle?

Naphezu kweminyaka edlule, izinjini ze-1.4 TDi zisatholakala ezimotweni eziningi ezisetshenzisiwe. Lokhu kusho ukuthi izinga labo lihle. Ngemuva kokuhlolwa okuningiliziwe kwesimo sobuchwepheshe beyunithi, kanye nemoto etholakala kuyo, ungathenga injini yekhwalithi enhle. Kulokhu, injini ye-1.4 TDi izoba yisinqumo esihle, futhi uzokwazi ukugwema izindleko ezengeziwe ngokushesha ngemva kokuthenga iyunithi.
