I-High Quality Diesel Fuel Injector 370-7287 Common Rail Fuel Injector 3707287 ye-Denso ye-Caterpillar CAT C4 Engine

Ama-injection kaphethiloli angcono kakhulu enza injini ikwazi ukukhiqiza amandla aphezulu kuyilapho inciphisa ukusetshenziswa kukaphethiloli futhi yehlisa ukungcoliswa. Izijovo zikaphethiloli ezinobuchwepheshe bamuva zisiza ukunciphisa ukukhishwa kwekhabhoni negesi ebamba ukushisa ngokuletha uphethiloli onembile ngokuxubana komoya okulungiselelwe. Lesi sihloko sichaza ukuthi iyini i-fuel injector nokuthi isebenza kanjani ezinjinini zikadizili, igesi yemvelo, ne-hydrogen kanye nasezimotweni ze-hydrogen fuel cell.

WENZANI UMJOVI WAMAFUTHA?

Umjovo kaphethiloli ulawula ukujova kukaphethiloli endaweni evuthayo yangaphakathi yenjini lapho ihlanganiswa nomoya bese ibaselwe. Igumbi lomlilo yilapho amandla amakhemikhali akudizili, i-hydrogen, negesi yemvelo eguqulwa abe amandla emoto. Uma icutshungulwa iyunithi yokulawula i-elekthronikhi (i-ECU), i-injector iletha inani elinembile likaphethiloli ukuze kuqinisekiswe ukuvutha okuphumelelayo.

USEBENZA KANJANI UJOVA UDESEL?

Isijojo sikaphethiloli enjinini ye-diesel siqukethe i-solenoid (uhlobo lukazibuthe kagesi), umlomo wombhobho, kanye nenaliti ngaphakathi komzimba womjovo. Izinjini zesimanje zikadizili ziwumjovo oqondile, okusho ukuthi uphethiloli ulethwa ngqo endaweni evuthayo.

Kusilinda, umoya ucindezelwa ukuya phezulu kwepiston. Njengoba i-piston isondela phezulu kwendlela yayo, isignali kagesi ithunyelwa ku-solenoid, okubangela ukuba inaliti yomjovo iphakame, futhi ivumele uphethiloli womfutho ophezulu (ofika ku-37,000 psi) ukuthi ugeleze ngombhobho uye egumbini elivuthayo ukuze uxubane nalo. umoya. Ngenxa yezinga lokushisa eliphakeme elidalwe ukucindezela, ingxube ye-air-fuel iyazishisa, idale amandla futhi ishayele amapiston enjini.

Inhlanganisela yomfutho ophakeme kaphethiloli kanye nezimbobo zombozo womjovo omuhle kakhulu kuqinisekisa ukuxutshwa kahle komoya nophethiloli ukuze kuhlangatshezwane nezindinganiso zokukhipha umoya eziqinile nakakhulu. Ezinjinini zikadizili, umjovo kaphethiloli ungashisa ama-pulse amaningi ngokushaywa kwamandla okukodwa okungasetshenziselwa ukudambisa umsindo nokulawula ukungcola.
