I-Diesel Fuel Injector Esezingeni Eliphezulu 338004X450 Izingxenye Zezimoto ze-FORD RANGER 2.8D

Njengoba izidingo zikazwelonke ezikhiqizweni zezimoto kanye nokusetshenziswa kukaphethiloli ziya ngokuya ziba namandla, ukuthuthukiswa kobuchwepheshe bezinjini zikadizili kuhamba ngendlela yokusebenza kahle kwamandla, ukusebenza kahle okuphezulu kwezinga lokushisa kanye nokukhipha umoya ophansi. Isizukulwane esisha sesistimu yomjovo ka-diesel fuel, i-high-pressure common-rail fuel system, iyisizukulwane esisha sesistimu yomjovo kadizili. Isistimu kaphethiloli kaloliwe enengcindezi ephezulu iyakwazi ukuhlanganisa ivolumu yomjovo kanye nokulawula isikhathi komjovo ibe iyunithi eyodwa, elawulwa ama-injection, futhi ingcindezi yomjovo izimele kwijubane nomthwalo wenjini. Umjovo uyisakhiwo esiyinkimbinkimbi kakhulu futhi uyingxenye ebalulekile yesistimu yokujova uphethiloli. Ukusebenza komjovo kunomthelela oqondile ekusebenzeni kwayo yonke isistimu yokujova uphethiloli wesitimela esinengcindezi ephezulu, nayo enomthelela omkhulu ekusebenzeni kwenjini. Ngakho-ke, kubalulekile ukuthuthukisa izici zomjovo zama-injection ujantshi ojwayelekile ohlelweni lokuthuthukiswa kokusebenza kwenjini.

Umjovo we-Common Rail olawulwa nge-elekthronikhi uqukethe izingxenye ezintathu ezisebenzayo: izijovo ze-orifice, amavalvu e-solenoid kanye nesistimu ye-hydraulic servo. Uphethiloli wengcindezi ephezulu uphakelwa kusukela kulayini kaphethiloli wengcindezi ephezulu iye emibhobolweni yomjovo, lapho udlula khona endaweni yokungena nokuphumayo bese ungena egumbini lokulawula. Igumbi lokulawula lixhunywe ku-orifice yokubuyisela uwoyela ngokusebenzisa i-throttle orifice yokubuya evulwe i-valve ye-solenoid. Lapho i-orifice yokubuya ivaliwe, ingcindezi engaphezulu kwe-valve yokujova yenaliti inkulu kunamandla endaweni yokucindezela engaphansi kwe-valve yokujova yenaliti, i-valve yokujova yenaliti icindezelwa ngokumelene nesihlalo sombhobho womjovo, futhi awekho amafutha angena ekamelweni elivuthayo. Lapho i-valve ye-electro-magnetic isebenza, i-orifice yokubuya iyavulwa futhi ingcindezi egunjini lokulawula iyehla. Uma amandla asebenza phezulu kwevalve yenaliti yomjovo engaphansi kwamandla asebenza endaweni ethwala ukucindezela yevalvu yenaliti yomjovo, ivalve yenaliti yomjovo iyavuleka ngokushesha bese uphethiloli ujovwa egumbini elivuthayo ngokusebenzisa imbobo yomjovo. Kule nqubo, ngaphezu kwenani likaphethiloli elijovwe ekamelweni elivuthayo, kukhona uphethiloli owengeziwe ogeleza ngaphandle kwe-throttle orifice, ebuyiselwa ku-tank fuel ngokusebenzisa isiteshi sokubuya.
