I-High Quality Common Rail Fuel Injector 0 445 120 083 Diesel Fuel Injector 0445120083

Isistimu kaphethiloli iyingxenye eyinhloko yenjini ye-diesel futhi inesibopho sokujova uphethiloli ekamelweni elivuthayo ngengcindezi efanele nangesikhathi esifanele. Iphampu yomjovo kanye nomjovo yizingxenye ezibalulekile zesistimu.

Okokuqala, indlela yokulungisa ukwehluleka kwephampu yomjovo kaphethiloli. Amaphutha avamile ahlanganisa ukuguga kwe-plunger, ukuvala ivalvu yokuletha uwoyela akuqinile, njll. Ngesikhathi sokulungiswa, i-plunger nevalvu yokuletha uwoyela kudingeka ihlolwe ngokucophelela futhi ishintshwe uma kunesidingo. Iphampu yomjovo kaphethiloli kagandaganda othile wezolimo yehlulekile, okubangele ubunzima ekuqaliseni injini yedizili kanye nokunciphisa amandla. Ngemva kokuhlola, kwatholakala ukuthi i-plunger yepompo yomjovo kaphethiloli yayiguge kakhulu futhi ivalvu yokukhipha uwoyela yayingavalwanga ngokuqinile, okubangele ukucindezela kukaphethiloli okwanele kanye nokunikezwa kukaphethiloli okungalingani. Sebenzisa isihloli somfutho wamafutha ukuze ulinganise futhi uthole ukuthi umfutho kaphethiloli uyashintshashintsha ebangeni elingu-15 ukuya ku-20MPa. Ngakho-ke, shintsha i-plunger egugile futhi ulungise indawo yokuvala ye-valve yokuletha uwoyela, futhi usebenzise amathuluzi okugaya akhethekile ukuze ugaye i-valve yokuletha uwoyela ukuze uqinisekise ukusebenza kwayo kokuvala. Ngemva kokushintshwa, ingcindezi kaphethiloli yazinza phakathi kwebanga elingu-22 kuya ku-24MPa. Ngemva kokulungiswa, injini ye-diesel yaqala kahle, amandla abuyela kwesijwayelekile, futhi izinga lokusetshenziswa kukaphethiloli nalo lehla kakhulu.

Okwesibili, indlela yokulungisa amaphutha omjovo. Amaphutha ajwayelekile ahlanganisa imibhobho evalekile, amavalvu yenaliti ebambekile, njll. Ngesikhathi sokulungiswa, umjovo udinga ukuhlakazwa, uhlanzwe futhi ulinganiswe. Umjovo wenjini kadizili womkhumbi othile awusebenzi kahle. Injini kadizili ikhipha intuthu emnyama futhi yandise ukusetshenziswa kukaphethiloli uma isebenza. Ngemva kokuhlakaza umjovo kaphethiloli, kwatholakala ukuthi kwakukhona ukunqwabelana okukhulu kwekhabhoni ngaphakathi emlonyeni, okuholela ekungangeni kahle kwe-atom kaphethiloli. Ibhentshi lokuhlola i-fuel injector lasetshenziselwa ukuhlolwa, futhi kwatholakala ukuthi umthamo womjovo kaphethiloli wawungalingani futhi umphumela we-atomization wawungemuhle. Sebenzisa i-ejenti yokuhlanza ekhethekile ukuze uhlanze amadiphozithi ekhabhoni ngaphakathi kubhobho, futhi ugaye i-valve yenaliti ukuze ubuyisele ukuguquguquka nokuvala kwayo. Ngemva kokuhlanza, yaphinde yahlolwa ebhentshini lokuhlola. Inani lomjovo kaphethiloli lalilingana futhi umphumela we-atomization waba ngcono kakhulu. Ngemuva kokulungiswa, intuthu emnyama yanyamalala ngesikhathi injini kadizili isebenza, izinga lokusetshenziswa kukaphethiloli labuyela kwesijwayelekile.
