Injini engu-1.5 dci - iyiphi iyunithi esetshenziswa ezimotweni zakwaRenault, Dacia, Nissan, Suzuki neMercedes?

Ekuqaleni, kufanelekile ukuqaphela ukuthi kunezinketho eziningi zale yunithi. Injini engu-1.5 dci itholakala ngezinguqulo ezingaphezu kuka-20. Sekuvele kunezizukulwane ezi-3 zamamotho ezimotweni, ezinamandla ahlukene. Kulesi sihloko uzothola ulwazi olubaluleke kakhulu!

Injini engu-1.5 dci nokuqala kwayo. Lalibonakala ngani iqembu lokuqala?

Idivayisi yokuqala eyakhishwa emakethe kwakuyi-K9K. Uvele ngo-2001. Bekuyi-four-cylinder turbo engine. Yayifakwe nesistimu yezitimela ezivamile futhi yanikezwa ngezilinganiso zamandla ahlukene ukusuka ku-64 kuya ku-110 hp. 

Umehluko phakathi kwezinguqulo zedrayivu ngayinye uhlanganisa: ama-injection ahlukene, ama-turbocharger noma ama-flywheels noma amanye. Injini engu-1.5 dci ihlukaniswa yisiko lokusebenza okusezingeni eliphezulu, ukusebenza okuhloniphekile ezinhlobonhlobo ezinamandla kakhulu kanye nomnotho - ukusetshenziswa kukaphethiloli isilinganiso samalitha angu-6 ngebanga lika-100 km. 

Izinhlobo ezahlukahlukene ze-1.5 dci - imininingwane yezinhlobo zemoto ngayinye

Kuyafaneleka ukufunda kabanzi mayelana nemininingwane yezinhlobo zenjini eziyi-1.5 dci. Ezibuthakathaka kuzo, ezikhiqiza i-65 hp, azifakwe i-flywheel elintantayo. Futhi abanayo i-geometry turbine ne-intercooler eguquguqukayo. Endabeni yale njini, uhlelo lomjovo lwakhiwe ngokubambisana nenkampani yaseMelika iDelphi Technologies. Isebenza ngengcindezi ye-1400 bar. 

82 hp inguqulo ihluke ngokuthi ifakwe i-intercooler kanye ne-turbo pressure ephezulu ukusuka ku-1,0 kuya ku-1,2 bar. 

100 hp inguqulo Ine-flywheel entantayo kanye ne-geometry turbine eguquguqukayo. Ingcindezi yomjovo nayo iphakeme - ukusuka ku-1400 kuya ku-1600 bar, njengokucindezela kwe-turbo boost, kubha engu-1,25. Endabeni yale yunithi, ukwakheka kwe-crankshaft nekhanda nakho kushintshiwe. 

Isizukulwane esisha seyunithi kusukela ngo-2010

Ngokuqala kuka-2010, kwethulwa isizukulwane esisha salolu phiko. Injini engu-1.5 dci isithuthukisiwe - lokhu kuhlanganisa i-valve ye-EGR, i-turbocharger, iphampu kawoyela. Abaqambi baphinde banquma ukusebenzisa uhlelo lwe-Siemens fuel injection. Kuphinde kusetshenziswe uhlelo lwe-Start-Stop, olucisha ngokuzenzakalelayo futhi luqale iyunithi yomlilo - ukuze kuncishiswe isikhathi sokungenzi lutho kwenjini futhi kuncishiswe ukusetshenziswa kukaphethiloli, kanye nezinga lobuthi begesi yokukhipha umoya.

Ingakanani injini engu-1,5 dci?

Izinzuzo ezinkulu zomnyango, okokuqala, ukonga izindleko kanye nesiko eliphezulu lomsebenzi. Ngokwesibonelo, injini diesel emotweni efana "Renault Megane" idla amalitha 4 ngebanga lika-100 km, futhi edolobheni - 5,5 amalitha 100 km. Ibuye isetshenziswe ezimotweni ezifana nalezi:

• Renault Clio, Kangoo, Fluence, Laguna, Megane, Scenic, Thalia или Twingo;
• UDacia Duster, uLodgy, uLogan noSandero;
• Nissan Almera, Micra K12, Tiida;
• Suzuki Jimny;
• Mercedes class A.

Ngaphezu kwalokho, ngokuvutha okuhle okunjalo, injini inomklamo olula, okuholela ezindlekweni eziphansi zokusebenza. Injini engu-1.5 dci nayo iqinile. Kodwa-ke, kufanele kukhunjulwe ukuthi izinga lokuhluleka kwe-node lingakhuphuka kakhulu ngemva kokudlula i-mileage ye-200 km eyizinkulungwane. km.

Izinga lokwehluleka 1.5 dci. Imaphi amaphutha avame kakhulu?

Uphethiloli wekhwalithi ephansi ubhekwa njengenye yezimbangela ezivame kakhulu zokuhluleka kweyunithi. Lokhu kungenxa yokuthi injini ayikubekezeleli uphethiloli osezingeni eliphansi. Lokhu kungaba yiqiniso ikakhulukazi kumabhayisikili enziwe ngezinto ze-Delphi. I-injector ezimweni ezinjalo ingasebenza kuphela ngemuva kwe-10000 km. 

Abashayeli abasebenzisa izimoto ezinamayunithi anamandla bakhala nangezinkinga. Bese kuba khona ukungasebenzi kahle okuhambisana ne-valve ye-EGR eyonakele, kanye ne-flywheel entantayo. Ukulungisa okumba eqolo nakho kuhlotshaniswa nesihlungi sezinhlayiyana ezilimele, okuthi, nokho, kuyinkinga ezinjinini eziningi zesimanje zikadizili. 

Ngezinye izikhathi kungase kube nokwehluleka okuhlobene ne-drive electronics. Isizathu esivame kakhulu ukugqwala okwenzeka ekufakweni kukagesi. Ngezinye izikhathi lokhu kuwumphumela wokulimala kwengcindezi noma izinzwa zokuma kwe-crankshaft. Kucatshangelwa zonke izimo eziveziwe zokuvela kokungasebenzi kahle, kufanelekile ukugcizelela indima yokusetshenziswa okufanele kwemoto, kanye nokugcinwa kweyunithi yamandla.

Ungayinakekela kanjani iyunithi ye-1.5 dci?

Ukuhlolwa okuphelele kunconywa phakathi kuka-140 no-000 km. Njengomphumela wokusebenza okunjalo, izinkinga ngohlelo lwe-elekthronikhi noma uhlelo lomjovo kungenzeka. 

Kuyafaneleka futhi ukushintsha uhlelo lomjovo njalo. Idalwe yiDelphi, kufanele ishintshwe ngemuva kwe-100 km. Ngakolunye uhlangothi, i-Siemens inokwethenjelwa kakhulu futhi ingahlala isikhathi eside, kodwa ukufaka esikhundleni sesistimu endala entsha kuyoba inselele yezezimali.

Ukusebenza okungenazinkinga kweyunithi isikhathi eside, kuyadingeka futhi ukushintsha uwoyela njalo. Kufanele ifakwe uphethiloli njalo ngemuva kuka-10000 km. Lokhu kuzosiza ukugwema izinkinga ezihambisana nomonakalo ku-crankshaft. Isizathu salokhu kungasebenzi ukwehla kokugcoba kwepompo yamafutha.

Ingabe injini ye-Renault 1.5 dci iyinjini enhle?

Imibono ngale yunithi ihlukene phakathi. Kodwa-ke, omunye angase athi isibalo sabantu abakhononda ngo-1.5 dci singancipha ukube bonke abashayeli bebesevisa izinjini zabo njalo futhi besebenzisa uphethiloli osezingeni eliphezulu. Ngesikhathi esifanayo, injini ye-diesel yaseFrance ingakhokha ngokusebenza okuzinzile nokusebenza kahle okuphezulu.
