Injini Epheleleyo : Injini yeHyundai-Kia D4CB

I-2.5-litre ye-Hyundai D4CB okanye i-2.5 CRDi injini ye-diesel ihlanganiswe eKorea ukususela ngo-2001 kwaye ihlaziywe kathathu ngeli xesha: kwi-EURO 3, 4, 5, ngokulandelanayo. Bayibeka kwiibhasi ezincinci ze-H-1 series, kwaye iyaziwa nakwisizukulwana sokuqala se-Kia Sorento.

IMVELISO INTSHAYELELO

Ngo-2001, injini ye-diesel ye-2.5-litre yaqala kwii-minibuses ze-H-1 kunye ne-Starex. Ngaphambi koku, i-Hyundai-Kia yavelisa ii-clones ze-Mitsubishi 4D56, kwaye injini entsha yahluke kakhulu: yayingaseyiyo injini ye-dizeli ye-vortex, kodwa iyunithi yanamhlanje kunye ne-Common Rail system. Kukho ibhloko ye-iron-cast for 4 cylinders, i-16-valve ye-aluminium intloko ene-hydraulic lifters, i-fancy three-chain timing drive, i-intercooler kwaye, ngokuqinisekileyo, ibhloko ye-balance shafts.

Zizonke, bekukho izizukulwana ezithathu zeenjini zedizili, ze-EURO 3, 4 kunye ne-5, ngokulandelanayo.

1.Isizukulwana sokuqala seyunithi sasixhotyiswe nge-Bosch Common Rail system kunye noxinzelelo oluya kuthi ga kwi-1360 bar, i-turbine ye-Garrett GT1752LS kwaye iphuhlise i-116 - 140 hp, kunye ne-314 - 343 Nm ye-torque.

2.Isizukulwana sesibini sasungulwa ngo-2006, kunye ne-1600 bar Bosch CR system kunye ne-BorgWarner BV43 variable geometry turbine, amandla anda ukuya kwi-170 hp kunye ne-392 Nm.

3.Isizukulwana sesithathu savela kwi-2011, nantsi i-CR Delphi eyahlukileyo kwi-bar ye-1800 kunye ne-MHI TD03L4 turbine. Umlinganiselo wokunyanzeliswa wehliswa ukusuka kwi-17.7 ukuya kwi-16.4, amandla ahlala efana, kwaye i-torque yanda ukuya kwi-441 Nm.

I-injini yafakwa kwi:

Hyundai Starex 1 (A1) ngo-2001 - 2007;

Hyundai Starex 2 (TQ) ukususela ngo-2007;

Kia Sorento 1 (BL) ngo-2002 – 2009.

Ukungalungi kwi-injini ye-Hyundai D4CB

Ngo-2008 kunye no-2009, injini yatshintshwa phantsi kwewaranti: intonga yokudibanisa yaphuka ngenxa yeebholithi eziphosakeleyo. Kwii-injini emva kwe-2011 kunye ne-Common Rail Delphi, impompo yamafutha yayihlala iqhuba iitshiphusi.

Ukungaphumeleli okudumileyo kule injini ye-diesel kukutshiswa kweewasha zobhedu phantsi kwemibhobho, okukhokelela ekuphekeni ngokukhawuleza kwe-injini kunye nemiphumo ebuhlungu kakhulu.

Enye ingxaki eqhelekileyo ngemoto enjalo ngumamkeli oyile ovalekileyo. Kuyacetyiswa ukuba uyijonge ngamaxesha athile okanye ngokungalindelekanga inokujika iilitha.

Indlela yokuhambisa igesi iqulethwe ngamatyathanga amathathu kwaye eyona ibuthathaka apha yile isezantsi, ejikeleza impompo yeoli kunye ne-balancers. Ngokuphuka kwayo, ikhonkco lexesha eliphambili lidla ngokuphuka.

Iilitha ze-crankshaft, izinyusi ze-hydraulic, inkqubo yokulawula i-vacuum kunye ne-turbocharger geometry inkqubo yokutshintsha kunye nevalve ye-EGR ayinaso isibonelelo siphezulu apha.
