Enjene 2KD-FTV
Enjene ea 2KD-FTV e hlahile ka lekhetlo la pele ka 2001. E ile ea e-ba moloko oa bobeli oa koloi ea 1KD-FTV. Enjene e ncha e ile ea fumana molumo oa lilithara tse 2,5, e leng 2494 cubic centimeters, ha pele ho eona ho ne ho e-na le molumo oa ho sebetsa oa lilithara tse peli feela.
Sehlopha se secha sa matla se ile sa fumana li-cylinders tsa bophara bo lekanang (limilimithara tse 92) le enjene ea litha e le 'ngoe, empa piston ea piston e ile ea e-ba kholoanyane' me ea fihla ho limilimithara tse 93,8. Enjene e na le li-valve tse leshome le metso e ts'eletseng, tse hlophisitsoeng ho latela morero oa khale oa DOHC, hammoho le turbocharger e nang le intercooler. Kajeno ke e 'ngoe ea lisebelisoa tsa motlakase tsa diesel tsa morao-rao tse entsoeng ke Toyota. Ha e le hantle, enjene ena e na le litšobotsi tse matla ho feta 1KD-FTV, empa matla a fokolang a ka fokotsa haholo tšebeliso ea mafura, e thusang ho boloka chelete.
Litlhaloso tsa theknoloji
Enjene ea 2KD-FTV ntle le tšebeliso ea supercharger e ka hlahisa matla a lipere a 101 (ka torque ea 260 N le 3400 rpm). Ha turbine e ntse e sebetsa, matla a eketseha haholo, 'me a batla a lekana le 118 horsepower (e nang le torque ea 325 N * m). Turbine e entsoeng ka Thai, e nang le mosebetsi oa ho fetola geometry ea nozzle, e u lumella ho ntlafatsa matla a fetang 142 horsepower (e nang le torque ea 343 N * m). Silinda ea mofuta ona oa enjene e entsoe ka tšepe e entsoeng ka tšepe, 'me pane ea oli le pompo e phodileng li entsoe ka motsoako oa aluminium. Motlakase o na le li-piston tse entsoeng ka motsoako o khethehileng oa aluminium, 'me o kopantsoe le molamu o kopanyang ka piston ea piston.
Tekanyo ea khatello ea enjene e ka ba 18,5: 1. Enjene e khona ho hlahisa ho feta 4400 rpm. Enjene ena e na le sistimi e ikhethileng e fanang ka ente e tobileng ea D4-D. Litšobotsi tsa 2KD-FTV li batla li tšoana le tsa pele ho eona, phapang e teng feela ka piston stroke le bophara ba silinda.

Ho sebelisa enjene ea mohlala ona
Likoloi tse joalo li na le mefuta e mengata e hlahisoang ke Toyota automaker, ho kenyelletsa:
- Toyota Innova;
- Toyota Fortuner;
- Toyota Hiace;
- Toyota Hilux.
Linaheng tse ling tsa Amerika Boroa le Bohareng, lienjineri tsena li na le likoloi tsa Toyota 4Runner ho fihlela ka 2006 ho lokolloa. Ho feta moo, baenjiniere ba Toyota ba rera ho hlomella mofuta o mocha oa Kijang ka eona. Ho theosa le lilemo tsa ts'ebetso, enjene ena e fumane lerato la bakhanni ho pota lefatše, ka lebaka la ts'epo ea eona le ts'ebetso e ntle ea matla.
Litlhahiso tsa tšebeliso
Litlhahlobo tse tsoang ho bakhanni ba likoloi li re bothata bo ka sehloohong ba lienjineri tsa mohlala ona ke li-nozzles, kaha ha li na moralo o atlehileng haholo. Beng ba likoloi tse nang le enjene ena ba hlokomela hore li tlameha ho fetoloa bonyane hang ka mor'a lilemo tse ling le tse ling tse tšeletseng. Ka lebaka la mafura a disele a boleng bo tlase, a nang le sebabole se phahameng, se rekisoang linaheng tse ngata, li-injection li tlameha ho fetoloa khafetsa. Ka lebaka lena, ho kgothaletswa ho sebelisa disele ea boleng bo holimo feela.
Ha u sebelisa Toyota 2KD-FTV, litseleng tse seretse, tse matsutla-tsutla tse koahetsoeng ke lehloa le qhibilihang, le litseleng tse fafalitsoeng ka letsoai le thibelang leqhoa, ho kgothaletswa ho boloka enjene kamehla. Ntle le moo, ho bohlokoa ho sebelisa oli ea lebitso feela e khothalelitsoeng ke moetsi, ho se latele molao ona o bonolo haufinyane ho tla lebisa tahlehelong ea matla a enjene, a ka hlokang ho lokisoa.
