Nyob rau hauv 2001, ib tug 2.5-liter diesel cav debuted ntawm lub H-1 thiab Starex minibuses. Ua ntej no, Hyundai-Kia tau tsim Mitsubishi 4D56 clones, thiab lub cav tshiab yog qhov txawv txav: nws tsis yog lub cav vortex-chamber diesel, tab sis ib chav tsev niaj hnub nrog Common Rail system. Muaj cam khwb cia hlau thaiv rau 4 lub tog raj kheej, 16-valve txhuas lub taub hau nrog hydraulic lifters, ib tug zoo nkauj peb-chain sij hawm tsav, ib tug intercooler thiab, ntawm chav kawm, ib tug thaiv ntawm tshuav shafts.
Nyob rau hauv tag nrho, muaj peb tiam ntawm xws li diesel xyaw, rau EURO 3, 4 thiab 5, feem.
1.Thawj tiam ntawm chav tsev tau nruab nrog Bosch Common Rail system nrog lub siab txog li 1360 bar, Garrett GT1752LS turbine thiab tsim 116 - 140 hp, nrog rau 314 - 343 Nm ntawm torque.
2.Lub sijhawm thib ob tau tshaj tawm hauv xyoo 2006, nrog 1600 bar Bosch CR system thiab BorgWarner BV43 hloov pauv geometry turbine, lub zog tau nce mus rau 170 hp thiab 392 Nm.
3.Qhov thib peb tiam tshwm sim nyob rau hauv 2011, ntawm no yog ib tug txawv CR Delphi ntawm 1800 bar thiab ib tug MHI TD03L4 turbine. Qhov sib piv compression tau qis los ntawm 17.7 mus rau 16.4, lub zog tseem zoo li qub, thiab lub zog torque tau nce mus rau 441 Nm.
Hauv xyoo 2008 thiab 2009, lub cav tau hloov pauv raws li kev lav phib xaub: lub pas txuas txuas tau tawg vim yog cov bolts tsis zoo. Nyob rau hauv cov cav tom qab 2011 nrog Common Rail Delphi, cov roj twj tso kua mis feem ntau tsav chips.
Lub nto moo tshaj plaws tsis ua hauj lwm ntawm no diesel cav yog qhov burnout ntawm tooj liab washers nyob rau hauv lub nozzles, uas ua rau kom ceev ceev coking ntawm lub cav nrog rau kev tu siab heev.
Lwm qhov teeb meem tshwm sim nrog xws li lub cev muaj zog yog cov khoom siv roj txhaws. Nws yog ib advisable mus xyuas nws ib ntus los yog poob nthav nws yuav tig lub liners.
Lub tshuab faib roj muaj peb cov saw hlau thiab qhov tsis muaj zog ntawm no yog qhov qis dua, uas tig cov roj twj tso kua mis thiab sib npaug. Nrog nws breakage, lub sij hawm tseem ceeb saw feem ntau kuj tawg.
Cov crankshaft liners, hydraulic lifters, lub tshuab nqus tsev tswj system thiab turbocharger geometry hloov qhov system thiab EGR valve tsis muaj qhov chaw siab tshaj ntawm no.
