2.0 HDi injini - izici zikadizili kwaPeugeot

Injini engu-2.0 HDi yaqala ukubonakala kwi-Citroen Xantia ngo-1998 futhi yanikeza i-110 hp. Khona-ke yafakwa kumamodeli afana ne-406, 806 noma i-Evasion. Kuyathakazelisa ukuthi lolu phiko lungatholakala kwezinye izimoto zakwaSuzuki noma zakwaFiat. Zakhiqizwa eSevel eValenciennes kusuka ngo-1995 kuya ku-2016. Injini yajabulela ukubuyekezwa okuhle ngokuvamile, futhi ukukhiqizwa kwayo kwakuyizigidi. Sethula ulwazi olubaluleke kakhulu ngaye.

Igama elithi HDI livelaphi?

Lona kanye igama elithi HDi lihlotshaniswa nohlobo lomklamo weyunithi yamandla, noma kunalokho ngomjovo oqondile kaphethiloli ngaphansi kwengcindezi ephezulu. Leli gama laqanjwa yiqembu le-PSA Peugeot Citroen izinjini zikadizili ezine-turbocharging, i-direct injection, nobuchwepheshe be-common rail, ubuchwepheshe obuthuthukiswe yi-Fiat ngeminyaka yama-90s. Ukusetshenziswa komjovo oqondile nakho kuye kwaholela esikweni lokushayela eliphakeme uma kuqhathaniswa nomjovo ongaqondile, isibonelo.

2.0 Injini ye-HDi - isimiso sokusebenza kweyunithi

Kuhle ukwazi ukuthi le njini engu-2.0 HDi isebenza kanjani. Kuyunithi, uphethiloli usakazwa ukusuka ethangini ukuya empompini yomfutho ophezulu ngokusebenzisa iphampu yokucindezela okuphansi. Bese kuqhamuka ujantshi we-high pressure fuel - okuyiCommon Rail system okukhulunywe ngayo phambilini. 

Ihlinzeka ngamabhomu alawulwa ngogesi anengcindezi enkulu engu-1500 bar. Lo mfutho uvumela uphethiloli ukuthi ufakwe kumasilinda ngendlela yokuthi kutholakale ukuvutha okungcono, ikakhulukazi uma kuqhathaniswa nezinjini ezindala. Lokhu kubangelwa ikakhulukazi i-atomization kaphethiloli we-diesel ube amaconsi amahle kakhulu. Ngenxa yalokho, ukusebenza kahle kweyunithi kuyanda.

Ukukhiqizwa kokuqala kweyunithi yamandla evela ku-PSA Group

Iqembu le-PSA - Peugeot Societe Anonyme lenze injini engu-2.0 HDi ezothatha indawo yezinjini ezindala zikadizili. Enye yezinhloso ezinkulu bekuwukunciphisa inani likaphethiloli osetshenziswayo, ukudlidliza nomsindo owenzeka uma ushayela imoto. Ngenxa yalokhu, isiko lomsebenzi weyunithi liye lathuthuka kakhulu futhi ukushayela ngale injini kuye kwaba mnandi kakhulu. 

Imoto enenjini engu-2.0 HDi ibibizwa ngeCitroen Xantia, lezi bekuyizinjini ezingu-90 no-110 hp. Amayunithi ajabulela idumela elihle - ayebonakala njengathembekile, eyongayo futhi esimanje. Kwakungenxa yabo ukuthi imodeli yemoto eyethulwa ngo-1998 yayithandwa ngabathengi, futhi iningi lamayunithi lalinamamayela amakhulu ngenxa yokusebenza okuzinzile.

Isizukulwane sesibili sophiko lwe-PSA Group

Ukwakhiwa kwesizukulwane sesibili seyunithi kwakuhlotshaniswa nokuqala kokubambisana neFord. Umphumela waba ukwanda kwamandla netorque, kanye nokuncipha kokusetshenziswa kukaphethiloli ngosayizi wenjini ofanayo. Ukuqala kokuthengiswa kwenjini ye-diesel ye-PSA kanye nomkhiqizi waseMelika kwaqala ngo-2003.

Isizathu esiyinhloko sephrofayili yeyunithi enobungani bemvelo kwakuyizidingo zezinga lokukhishwa kwe-Euro 4, elaqala ukusebenza ngo-January 1, 2006. Injini yesizukulwane sesibili engu-2.0 HDi ayifakwanga kuphela kwaPeugeot, Citroen kanye nezimoto zaseMelika, kodwa nasezimotweni zakwaVolvo, Mazda, Jaguar neLand Rover. Ezimotweni zakwaFord, ubuchwepheshe benjini kadizili babubizwa nge-TDCI.

Okuvame kakhulu ukuhluleka kwenjini engu-2.0 HDi yi-turbo. Yini okufanele uyiqaphele?

Okunye okuvamise ukuhluleka kwenjini engu-2.0 HDi ukuhluleka kwe-turbocharged. Lona umphumela wokunqwabelana kwekhabhoni ku-aggregate. Ukungcola kungabangela izinkinga eziningi ezibizayo futhi kwenze ukuphila kube nzima kumnikazi wemoto. Khona-ke yini okufanele uyiqaphele?

Ukuvala uwoyela kanye nokwakheka kwensisi

Kumayunithi - womabili angu-2.0 no-1.6 HDi, inani elikhulu lensisi linganqwabelana endaweni yenjini. Ukusebenza kahle kwenjini kuncike kakhulu emigqeni kawoyela ukuya nokubuya ku-turbocharger. Kungenxa yabo ukuthi amafutha adlula, okunikeza ukugcoba kwama-bearings. Uma kukhona amadiphozithi ekhabhoni amaningi, imigqa izovimba futhi inqamule ukunikezwa kukawoyela. Ngenxa yalokho, ama-bearings ngaphakathi kwe-turbine angashisa ngokweqile. 

Izimpawu okungatholakala ngazo ukungasebenzi kahle

Indlela yokubona ukuthi uwoyela awasabalalisi kahle ukukhulula noma ukukhulula i-turbo nut. Lokhu kungenzeka kubangelwa ukuvaleka kwamafutha kanye nokwakheka kwekhabhoni. Inathi ngokwalo ezinjinini ezingu-2.0 HDi liyazivala futhi liqiniswa ngesandla kuphela. Lokhu kungenxa yokuthi idonswa phezulu lapho i-turbocharger isebenza kahle - ngenxa yezikulufu ezimbili ezihamba ngendlela ehlukile kanye nokudlidliza kwe-torsional.

Ezinye Izimbangela Eziholela Ekuhlulekeni Kwengxenye

Kunezinye izizathu zokuthi kungani i-turbo enjinini engu-2.0 HDi ingahluleka. Imvamisa kuba khona izinto zakwamanye amazwe ezingene kule nto, izigxivizo zikawoyela ezigqokiwe, ukusetshenziswa kwamafutha okucaciswa okungalungile, noma ukungahambisani nokugcinwa okuvamile kwesici.

Ungayinakekela kanjani injini engu-2.0 HDi?

Indlela engcono kakhulu yokuqinisekisa ukusebenza kahle kwenjini engu-2.0 HDi ukusevisa iyunithi njalo, njengokushintsha ibhande lesikhathi noma ukuhlanza isihlungi sezinhlayiyana zedizili. Kungaba umqondo omuhle futhi ukulawula inani lamafutha ekamelweni futhi usebenzise uhlobo olulungile lwamafutha. Kudingeka futhi ukuqinisekisa ukuhlanzeka kanye nokungabikho kwezinto zangaphandle ekamelweni leyunithi. Ngenxa yezixazululo ezinjalo, injini izokubuyisela ngokusebenza okubushelelezi nokuthembekile, okuletha injabulo enkulu yokushayela.
