Iphutha le-EDC

Inkomba yephutha kudeshibhodi

Iphutha le-EDC ikhombisa ukuwohloka kwesistimu yokulawula i-elekthronikhi yokujova uphethiloli enjinini kadizili. Ukubukeka kwaleli phutha kuphawulwe kumshayeli ngegama elifanayo. Isibani se-EDC. Kungaba nezizathu eziningi zephutha elinjalo. Kodwa okuyinhloko ukuvala isihlungi sikaphethiloli, izinkinga ekusebenzeni kwama-injection, ukuwohloka kwepompo likaphethiloli, ukushayela imoto, uphethiloli ophansi, njalonjalo. Kodwa-ke, ngaphambi kokudlulela kuzimbangela zangempela zephutha likaphethiloli, udinga ukuthola ukuthi iyini isistimu ye-EDC, ukuthi iyini, futhi yimiphi imisebenzi eyenzayo.

Iyini i-EDC futhi ihlanganisani

EDC (I-Electronic Diesel Control) iwuhlelo lokulawula udizili ngogesi olufakwa ezinjinini zesimanje. umsebenzi wayo oyisisekelo ukulawula ukusebenza komjovo kaphethiloli. Ngaphezu kwalokho, i-EDC iqinisekisa ukusebenza kwezinye izinhlelo zemoto - ukushisa, ukupholisa, isistimu yokukhipha umoya, i-exhaust gas recirculation system, turbocharging, intake and fuel systems.

Ngomsebenzi walo, uhlelo lwe-EDC lusebenzisa ulwazi oluvela kuzinzwa eziningi, phakathi kwazo: inzwa ye-oxygen, i-boost pressure, izinga lokushisa lomoya, izinga lokushisa likaphethiloli, izinga lokushisa elipholile, ukucindezela kukaphethiloli, imitha ye-air mass, i-accelerator pedal position, iHholo, isivinini se-crankshaft, ukunyakaza kwesivinini. , izinga lokushisa likawoyela, umzuzu wokuqala womjovo (fafaza uhambo lwenaliti), ukucindezela komoya wokungena. Ngokusekelwe kulwazi oluvela kuzinzwa, iyunithi yokulawula emaphakathi yenza izinqumo futhi izibike kumadivayisi asayindayo.

Lezi zindlela ezilandelayo zisebenza njengamadivayisi okusebenzisa wesistimu:

• okuyisisekelo nokwengeziwe (kwamanye amamodeli edizili) iphampu yesibaseli;
• imibhobho yomjovo;
• dosing valve high pressure fuel futha;
• isilawuli sengcindezi yamafutha;
• ama-motor kagesi okushayela ama-dampers angenayo kanye nama-valve;
• i-valve yokulawula ingcindezi yokuthuthukisa;
