VW EA188 udizili

Ulayini wezinjini zikadizili ezingama-4-cylinder in-line ezineVolkswagen EA188 unit injectors zakhiqizwa kusukela ngo-1996 kuya ku-2010 ngamavolumu amabili angu-1.9 kanye ne-2.0 TDI.

Izinhlobonhlobo zezinjini ze-Volkswagen EA188 1.9 kanye ne-2.0 TDI zahlanganiswa kusukela ngo-1996 kuya ku-2010 futhi zafakwa kuzo zonke izinhlobo zezinhlobo ze-VW ezikhathazayo nasezimotweni zabanye abakhiqizi. Ngokusemthethweni, lo mndeni wawuhlanganisa izinjini zikadizili i-1.2 TDI ne-1.4 TDI, kodwa kukhona okuhlukile ngazo.

Okuqukethwe:

• I-Powertrains 1.9 TDI
• I-Powertrains 2.0 TDI

Izinjini zikadizili EA188 1.9 TDI

Izinjini ze-diesel ezinama-injection epompo zavela ngo-1996, kodwa zaqala ukufakwa eminyakeni emibili kamuva. Kusukela kwabandulela uchungechunge lwe-EA 180, izinjini ezintsha azihlukanga kuphela ohlelweni lomjovo, kodwa futhi lapho kungekho shaft ephakathi, iphampu kawoyela yayizungeza iketango elihlukile ku-crankshaft. Omunye umehluko ophawulekayo lapha kwaba: isihlungi sikaphethiloli esibekwe mpo, idrayivu yepompo ye-vacuum esuka ku-camshaft, iphampu yesistimu yokupholisa eyakhelwe ngaphakathi kwebhulokhi yenjini.

Amayunithi wamandla angu-1.9-litre olayini ayekhona kuphela enguqulweni yamavalvu ayisishiyagalombili, lapho i-camshaft eyodwa yayizuliswa ngebhande lesikhathi eliqiniswe kakhulu eline-hydraulic tensioner. Ngokwesiko lakudala le-VW ukukhathazeka, kwakukhona ama-hydraulic lifter ekhanda le-aluminium yebhulokhi. Futhi, ukuguqulwa okunamandla kwase kunamaturbine esimanje anejiyomethri eguquguqukayo.

Sekukonke, izinhlobo ezingaba ngu-30 zezinjini ze-diesel ziyaziwa, sibala kuphela ezidume kakhulu kuzo:

1.9 TDI 8V (1896 cm³ 79.5 × 95.5 mm)

I-AJM	115 h.p.	285 Nm
AWX	130 h.p.	285 Nm
I-AVF	130 h.p.	310 Nm
Ay	115 h.p.	310 Nm
I-ACE	130 h.p.	310 Nm
I-AVB	101 h.p.	250 Nm

I-BKC	105 h.p.	250 Nm
BXE	105 h.p.	250 Nm
BLS	105 h.p.	250 Nm
I-AXB	105 h.p.	250 Nm
I-AXC	86 h.p.	200 Nm

Izinjini zikadizili EA188 2.0 TDI

Ngo-2003, umugqa we-EA188 wezinjini ze-diesel wanda ngezinjini ze-diesel ezingu-2.0-litre, okungafani nabafowethu abancane, ezazikhona kuzo zombili izinguqulo ezingu-8 nezingu-16-valve. Futhi, iyunithi enamalitha amabili ithole uhlelo olulula lokuqala olufana namapulaki akhanyayo, i-intercooler eshintshwayo kanye nenzwa yokuzungezisa eyakhelwe ngqo ku-crankshaft oil seal housing.

Kuyafaneleka ukukhumbula izinjini ezibuyekeziwe zeminyaka yokugcina yokukhiqiza, ngezinye izikhathi zibizwa ngokuthi i-EVO. Umehluko omkhulu phakathi kwenjini evuthayo yangaphakathi kwakuyizimbobo zephampu zakamuva ezine-valve ye-piezoelectric, nokho, ama-servicemen amaningi acebisa ukugwema lawa mayunithi amandla emakethe yesibili.

Siyazi ngokuguqulwa kwe-19 kwezinjini ze-diesel, kodwa lapha sibhala kuphela ezivame kakhulu:

2.0 TDI 8V (1968 cm³ 81 × 95.5 mm)

BMM	140 h.p.	320 Nm
BMP	140 h.p.	320 Nm

I-BPW	140 h.p.	320 Nm
I-BRT	140 h.p.	310 Nm

2.0 TDI 16V (1968 cm³ 81 × 95.5 mm)

I-BKD	140 h.p.	320 Nm
I-BKP	140 h.p.	320 Nm

I-BMR	170 h.p.	350 Nm
Bre	140 h.p.	320 Nm

Kusukela ngo-2007, lezi zinjini zikadizili seziqalile ukushintshwa ngezinjini zochungechunge ze-EA189 ngohlelo lwe-Common Rail.
