Izindlela zokunakekela injini ye-diesel fuel injection pump

(1) Sebenzisa amafutha edizili nezihlungi ezinhle ukuqinisekisa ukuthi uwoyela wedizili ongena empompini yokujova uphethiloli uhlanzeke kakhulu.
Ngokuvamile, izidingo zokuhlunga zezinjini zikadizili zikawoyela we-diesel ziphakeme kakhulu kunezinjini zikaphethiloli zikaphethiloli. Lapho usebenzisa izinjini zikadizili, kufanele ukhethe uwoyela wedizili ohlangabezana nezidingo, futhi kufanele udonse okungenani amahora angama-48. Qinisa ukuhlanzwa nokugcinwa kwesihlungi sikadizili, ukuhlanza noma ukubuyisela into yokuhlunga ngesikhathi; hlanza ithangi likadizili ngesikhathi ngokwezimo zendawo yokusebenza, futhi ususe ngokuphelele udaka namanzi ngaphansi kwethangi likaphethiloli. Ukugqwala okukhulu noma ukuguga kokuhlangana kwe-valve nezingxenye zokudlulisela.
(2) Njalo hlola ukuthi inani likawoyela kanye nekhwalithi echibini likawoyela lephampu yomjovo kawoyela liyahlangabezana yini nezidingo
Ngaphambi kokuqala injini ye-diesel, inani kanye nekhwalithi kawoyela empompini yokujova uphethiloli kufanele ihlolwe (ngaphandle kwephampu yomjovo kaphethiloli ephoqeleka ukuba igcobe ngenjini), ukuze kuqinisekiswe ukuthi inani likawoyela lanele kanye nekhwalithi. kuhle. Uma uwoyela wenjini uwohloka ngenxa yokuxubana namanzi noma uwoyela wedizili, kuzodala ukuguga ngaphambi kwesikhathi kwe-plunger kanye nokuhlanganiswa kwevalvu yokukhipha uwoyela, okuholela ekungeneni kwamandla enjini kadizili kanye nobunzima bokuqalisa. Ezimweni ezimbi kakhulu, kuzodala ukugqwala nokugqwala kwe-plunger kanye nomhlangano wevalvu yokukhipha uwoyela. Ukuvuza kwangaphakathi kwephampu kawoyela, ukusebenza kabi kwe-valve yokukhipha uwoyela, ukuguga kwetappet kanye nembobo yepompo yokulethwa kukawoyela, kanye nokulimala kwendandatho yokuvala kuzobangela ukuthi uwoyela udizili uvuze echibini likawoyela futhi unciphise uwoyela wenjini, kufanele ishintshwe ngesikhathi ngokuvumelana nekhwalithi yamafutha enjini. Uma ushintsha, ichibi lamafutha kufanele lihlanzwe kahle ukuze kukhishwe ukungcola okufana nodaka ngaphansi kwechibi lamafutha, ngaphandle kwalokho uwoyela uzowohloka ngemva kwesikhathi esifushane sokusetshenziswa. Inani lamafutha enjini akufanele libe liningi kakhulu noma libe lincane kakhulu. Amafutha amaningi kakhulu kumbusi azokwenza kalula injini ye-diesel "ijubane". Ngaphezu kwalokho, lapho injini ye-diesel ingasetshenzisiwe isikhathi eside, qiniseka ukuthi ubheka ukuthi kukhona yini amanzi, udizili nokunye ukungcola emafutheni echibini lamafutha lepompo likawoyela, bese uyibuyisela ngokushesha uma kukhona, ngaphandle kwalokho, ekugcinweni kwesikhathi eside, amanzi azolimaza kalula i-plunger kanye ne-valve yokukhipha uwoyela. Ngisho nezingxenye zigqwalile, zibhajwe futhi zilahliwe.
