1.9 Injini ye-SDi yakwaVolkswagen - ulwazi olubaluleke kakhulu mayelana neyunithi
Okuqukethwe
Isandiso sesifinyezo se-SDi Ukumunca umjovo wedizili – kufanele kuqashelwe ukuthi leli gama ngezinye izikhathi liyasetshenziswa Umjovo oqondile wedizili. Leli igama lokumaketha elihloselwe ngokuyinhloko ukuhlukanisa izinjini ezintsha kumamodeli wokuqokwa we-SD angasebenzi kahle − ukumunca udizili, nayo eyakhiwe ngabakwaVolkswagen. Injini engu-1.9 SDi ingeyaleli qembu. Funda kabanzi ngalokhu esihlokweni sethu!
Ulwazi oluyisisekelo mayelana nezinjini ze-VW ezifisa ngokwemvelo
Okokuqala, kufanelekile ukufunda okwengeziwe mayelana nobuchwepheshe be-SDI bobunikazi be-Volkswagen. Lona umklamo osetshenziswa ekukhiqizeni amayunithi edizili afisa ngokwemvelo afakwe umjovo oqondile.
Izinjini ze-SDi zisetshenziswa kakhulu ezimotweni nasemavenini. Ubuchwepheshe Ukumunca umjovo wedizili ibuye isetshenziswe ezinhlelweni zokuqhuba imikhumbi nezimoto zezimboni, ezithuthukiswa ngonjiniyela bakwa-VW Marine kanye ne-VW Industrial Motor.
Ikuphi ukucushwa atholakala kukho amadrayivu e-SDi?
Kuyaphawuleka ukuthi izinjini zalolu chungechunge zitholakala kuphela kumugqa we-in-line noma umugqa oqondile onegama elithi R4 no-R5. Ukusatshalaliswa kuhlanganisa izinjini ezine-displacement 1,7 litres kuya ku-2,5 litres kuzo zombili izinhlelo. Ukucaciswa okuqondile kungahluka kuye ngokusetshenziswa okuhlosiwe kwenjini.
Injini ye-SDi 1.9, njengezinye izinguqulo, ifakwe ikakhulukazi kulawo mamodeli ezimoto lapho ukwethembeka nokusebenza kahle kokushayela kubaluleke kakhulu. Lokhu kungenxa yokuthi abasebenzisi isixazululo esakhayo njengokungena komoya okuphoqelelwe. Nokho, lokhu kuhumusha emandleni enjini amancane uma kuqhathaniswa nezinjini ezifakwe i-turbocharging yomjovo oqondile.
1.9 SDi injini - idatha yobuchwepheshe
Lena injini enamasilinda amane etholakala ku-SDi fuel injection. Ukususwa kwenjini okuqondile ngu-1 cm³, isilinda bore 896 mm, i-stroke 79,5 mm. Isilinganiso sokucindezela singu-95,5:18,5.
Injini engu-1.9 SDi ilawulwa yi-Bosch EDC 15V+ yokulawula i-electronic unit. Isisindo esomile singama-198 kg. Isithuthuthu sinikezwe amakhodi okuhlonza AGD, AGP, ASX, ASY, AYQ kanye ne-AQM.
Dizayina izixazululo enjinini ye-VW
Abaklami bakhethe ibhulokhi yesilinda yensimbi empunga, kanye namabheringi amakhulu amahlanu kanye ne-crankshaft yensimbi eyenziwe ngomgunyathi. Idizayini ihlanganisa nekhanda le-aluminium alloy cylinder elicijile kanye nokuhlelwa kwama-valve amabili isilinda, ngengqikithi yama-valve ayisishiyagalombili. Iyunithi futhi inabalandeli benkomishi kanye ne-camshaft eyodwa ephezulu (SOHC).
Yini enye eyenza lo mklamo ugqame?
Injini engu-1.9 SDi ine-exhaust manifold (i-cast iron) kanye ne-intake manifold (i-aluminium alloy). Mayelana nesistimu kaphethiloli nezilawuli, iVolkswagen ifake iphampu yomjovo ene-Bosch VP37 electronic distributor nomjovo oqondile onezimbobo ezinhlanu.
Iyunithi futhi inesistimu yokupholisa eyiziyingi ezimbili enezishintshi zokushisa, elawulwa yi-thermostat. Idizayini ihlanganisa futhi:
- i-collective exhaust uhlelo lokupholisa amanzi;
- ipayipi lokukhipha;
- i-radiator kawoyela;
- uwoyela we-hydraulic.
Yiziphi izimoto ezifakwe injini engu-1.9 SDi?
Injini ifakwe ezimotweni zakwaVolkswagen ukukhathazeka. Mayelana nohlobo lwabazali uqobo, lezi izinhlobo zeVW Polo 6N/6KV, Golf Mk3 noMk4, Vento, Jetta King nePioneer kanye neCaddy Mk2. Ngakolunye uhlangothi, ezimotweni ze-Skoda lokhu kwenzeka ngamakhophi e-Fabia. Injini engu-1.9 SDi iphinde yanika amandla i-Seat Inca ne-Leon Mk1.
Ingabe ukushayela kweVolkswagen kuyimpumelelo?
Injini ibonakala ngokuvutha okuphumelelayo, okusho ukuthi iyunithi yamasilinda amane e-inline inikeza izindleko eziphansi zokusebenza - ngamandla aphezulu futhi ingathola imayela eliphezulu ngaphandle kwezinkinga ezinkulu.
Ngaphezu kwalokho, ihambisana nemvelo. Lokhu kuzuzwe ngenxa yesistimu yesimanje yokujova uphethiloli eqinisekisa amazinga aphansi okukhipha umoya. Ngokulandelayo, ngenxa yokusetshenziswa kwe-camshaft eyodwa ephezulu, ukwakheka kwedrayivu kulula, ukulungiswa nokugcinwa kuyinkimbinkimbi.
Ubuchwepheshe be-SDi bujabulela ukubuyekezwa okuhle. Ukwethulwa kwayo ezimotweni kube yimpumelelo enkulu, kanti enye yezinjini esebenza kahle kakhulu yalolu hlelo injini engu-1.9 SDi.
