1.4 TDi VW engine - txhua yam koj xav paub hauv ib qho chaw!

Lub cav 1.4 TDi tau teeb tsa hauv Volkswagen, Audi, Skoda thiab Seat tsheb, i.e. tag nrho cov manufacturers ntawm VW pawg. Lub diesel nrog kev txhaj tshuaj ncaj qha yog tus cwj pwm los ntawm kev lag luam zoo, tab sis kuj tseem muaj lub suab cuam tshuam nrog kev mob tsis zoo, piv txwv li, muaj zog vibrations lossis teeb meem nrog kev kho lub aluminium crankcase. Yog tias koj xav paub ntau ntxiv txog 1.4 TDi, peb caw koj nyeem cov ntawv seem.

Volkswagen's TDi cav tsev neeg - cov ntaub ntawv yooj yim

Ib tug yam ntxwv feature yog siv Turbocharged Direct Injection tshuab. Turbocharged diesel xyaw kuj tau nruab nrog intercooler. Nws yog ib qho tsim nyog sau cia tias Volkswagen teeb tsa lawv tsis yog ntawm lub tsheb xwb, tab sis kuj nyob rau hauv Volkswagen Marine nkoj, nrog rau ntawm Volkswagen Industrial Motor Industrial units.

Thawj TDi lub cav yog ib qho inline tsib-lub tog raj kheej cav uas tau qhia hauv 1989 nrog Audi 100 TDi sedan. Cov nroj tsuag tau modernized nyob rau hauv 1999. Cov neeg tsim qauv ntxiv rau nws lub Common Rail roj txhaj tshuaj. Yog li nws yog nrog lub cav V8, uas tau nruab rau ntawm Audi A8 3.3 TDi Quattro. Interestingly, TDi cav kuj tau siv nyob rau hauv kev sib tw tsheb nyob rau hauv lub LMP1 qeb.

Kev sib xyaw ntawm ob lub thev naus laus zis - kev txhaj tshuaj ncaj qha thiab turbocharging

Nyob rau hauv thawj rooj plaub, cov roj injector system sprays diesel roj ncaj qha mus rau hauv lub ntsiab combustion chamber. Yog li, cov txheej txheem combustion ua tiav ntau dua li hauv prechamber, lub npe hu ua. kev txhaj tshuaj ncaj qha, uas ua rau kom lub zog nce ntxiv thiab txo cov pa emissions. 

Nyob rau hauv lem, lub tso pa turbine compresses lub intake cua thiab tsub kom lub zog thiab torque nyob rau hauv ib tug compact, tsawg-tsav chav tsev. Tsis tas li ntawd, TDi cov cav tov tau nruab nrog lub intercooler kom txo qhov kub thiab nce qhov ceev ntawm cov cua compressed ua ntej nws nkag mus rau hauv lub tog raj kheej.

TDi yog lo lus lag luam.

Nws yog siv los ntawm cov npe uas muaj los ntawm Volkswagen Group, nrog rau Land Rover. Ntxiv rau qhov kev xaiv TDi, Volkswagen kuj tseem siv SDi - Suction Diesel Txhaj Tshuaj rau cov qauv uas tsis yog-turbo nrog kev txhaj tshuaj ncaj qha.

1.4 TDi engine - cov ntaub ntawv yooj yim

Qhov no peb-lub tog raj kheej chav tsev, uas tau tsim nyob rau hauv 2014 los hloov lub 1,2-liter qauv los ntawm EA189 tsev neeg, kuj tau siv los hloov lub plaub-lub tog raj kheej 1,6 TDi. Interestingly, lub tsev me me siv qee qhov ntawm lub cav plaub-lub tog raj kheej uas tau hloov mus rau peb lub tog raj kheej.

Lub cav 1.4 TDi tau tsim los ua ib txoj haujlwm txo qis. Ib qho kev ntsuas yog txo qhov hnyav ntawm lub crankcase thiab lub tog raj kheej sab, cov ntsiab lus no tau ua los ntawm ALSiCu3 alloy tau los ntawm lub ntiajteb txawj nqus casting. Raws li qhov tshwm sim, qhov hnyav ntawm lub cav tau raug txo los ntawm ntau npaum li 11 kg piv rau yav dhau los 1,2l TDi cav thiab 27 kg sib dua li 1,6l TDi.

Nyob rau hauv lub tsheb qauv yog lub 1.4 TDi engine ntsia?

Kev tsav tsheb los ntawm tsev neeg EA288 tau teeb tsa rau ntawm cov tsheb xws li:

• Audi: A1;
• Qhov chaw: Ibiza, Toledo;
• Skoda: Fabia III, Rapid;
• Volkswagen: Polo V.

Tsim cov kev daws teeb meem los ntawm Volkswagen engineers

Lub hwj chim chav tsev tau haum nrog qhov sib npaug ntawm cov ncej uas tau tsav los ntawm 1: 1 ib qho ceev gearbox nyob rau hauv qhov kev taw qhia rau lub crankshaft. Lub piston stroke kuj tau nce mus rau 95,5 hli, tso cai rau kev hloov pauv loj dua.

Lwm cov qauv tsim muaj xws li plaub li qub rau ib lub tog raj kheej, ob lub DOHC camshafts, thiab kev siv tib lub tog raj kheej lub taub hau tsim muaj nyob rau hauv plaub lub tog raj kheej MDB cav. Kuj tseem xaiv tau dej txias, intercooler, catalytic converter, DPF system, dual-circuit tso pa roj recirculation nrog qis thiab siab EGR, nrog rau DFS 1.20 txhaj tshuaj los ntawm cov chaw tsim tshuaj paus Delphi.

Technical data - engine specification 1.4 TSI

Lub cav 1.4 TDi siv cov txhuas lub tog raj kheej thaiv thiab lub tog raj kheej. Nws yog ib hom kev tsheb ciav hlau diesel, 4-kab, peb-lub tog raj kheej teeb tsa nrog plaub li qub rau ib lub tog raj kheej hauv DOHC cov tswv yim. Lub tog raj kheej nyob rau hauv lub maus taus muaj ib txoj kab uas hla ntawm 79,5 hli, thiab lub piston stroke mus txog 95,5 hli. Tag nrho cov cav muaj peev xwm yog 1422 cu. cm, thiab compression piv yog 16,1: 1.

Muaj nyob rau hauv 75 HP, 90 HP qauv. ib 104hp Rau kev siv lub cav kom raug, VW 507.00 thiab 5W-30 roj yuav tsum tau. Nyob rau hauv lem, lub peev xwm tank rau cov khoom no yog 3,8 litres. Nws yuav tsum tau hloov txhua 20 XNUMX. km.

Tsav kev ua haujlwm - teeb meem dab tsi?

Thaum siv lub cav 1.4 TDi, teeb meem nrog lub twj tso kua mis yuav tshwm sim. Tus nqi ua haujlwm tsis zoo pib tom qab kev khiav ntawm kwv yees li 200 km. km. Kev tuav cov nplhaib tseem faulty. Cov bushings hnav sai sai thiab tau teev raws li ib qho ntawm cov tsis muaj zog tshaj plaws ntawm lub rooj sib txoos tsav. Vim yog lawv, ntau axial ua si ntawm lub crankshaft yog tsim.

DPF cov ntxaij lim dej tseem raug kaw, uas ua rau muaj teeb meem ntau ntawm cov tsheb uas tsis tshua muaj mileage. Lwm qhov chaw uas yuav tsum tau saib xyuas tshwj xeeb muaj xws li: lub cav injectors, flow meters thiab tau kawg lub turbocharger. Txawm hais tias qhov tseeb tias chav tsev tau nyob hauv kev ua lag luam tau ntev, kev kho tus kheej tuaj yeem ua rau cov nqi tseem ceeb. 

Puas yog 1.4 TDi xaiv zoo?

Txawm hais tias xyoo dhau los, 1.4 TDi cav tseem muaj nyob rau ntau lub tsheb siv. Qhov no txhais tau tias lawv qhov zoo yog qhov zoo. Tom qab tshawb xyuas cov ncauj lus kom ntxaws ntawm cov txheej txheem ntawm chav tsev, nrog rau lub tsheb uas nws nyob, koj tuaj yeem yuav lub cev muaj zog zoo. Hauv qhov no, lub cav 1.4 TDi yuav yog qhov kev xaiv zoo, thiab koj yuav zam tau cov nqi ntxiv tam sim ntawd tom qab kev yuav tsev.
