I-Hot Selling New Diesel Injector 23670-09380 Common Rail Injector ye-Denso Auto Parts

Isigaba sangaphambi kwesikhathi: Umlando wama-injection kaphethiloli ungalandelelwa emuva ezinsukwini zokuqala zokuthuthukiswa kwezinjini ezivuthayo zangaphakathi. Ngaleso sikhathi, ama-injection kaphethiloli ayelula futhi imisebenzi yawo yayiyisisekelo.
Izijovo zikaphethiloli ezilawulwa ngomshini: Ngokuthuthuka kobuchwepheshe, kwavela izijovo zikaphethiloli ezilawulwa ngomshini. Isibonelo, ezinjinini zikadizili, iphampu kaphethiloli enengcindezi ephezulu ishayelwa i-camshaft yenjini ukuletha uphethiloli emakamelweni kaphethiloli esilinda ngasinye. Kodwa-ke, le ndlela yokuphakela uphethiloli iyashintsha ngesivinini senjini, okwenza kube nzima ukuthola ukulawulwa kokuphakelwa kukaphethiloli okufanelekile ngesivinini esihlukahlukene.
Ukuthuthukiswa kwama-injection kaphethiloli alawulwa nge-elekthronikhi: Ukuze ulawule ngokunembe kakhudlwana inqubo yokujova, kwaba khona izijovo zikaphethiloli ezilawulwa nge-elekthronikhi. Kusukela ngawo-1950, ubuchwepheshe bomjovo kaphethiloli sebuqalile ukudonsa amehlo. Izinkampani zokuqala ezisebenzisa umjovo kaphethiloli ezinjinini zezimoto zavela phakathi kuka-1950 no-1953 nango-1957. Ngo-1953, i-Bendix yaqala ukuthuthukisa ama-injection kaphethiloli alawulwa nge-elekthronikhi futhi yawakhulula esidlangalaleni ngo-1957. ukuthuthukiswa kwama-injection kaphethiloli. Isebenzisa i-electronic control unit (ECU) ukulawula ukuvulwa nokuvalwa kwe-valve ye-solenoid, ngaleyo ndlela izuze ukulawula okunembile kwesikhathi somjovo, inani lomjovo kanye nezinga lomjovo. Uma kuqhathaniswa nezindlela zendabuko zokulawula imishini, ama-injection alawulwa nge-elekthronikhi anokuguquguquka okuphezulu nokunemba.
Ama-injection ohlelweni olujwayelekile lukaloliwe: Ukuvela kohlelo olujwayelekile lokuhlinzeka ngophethiloli womjovo wesitimela kuqhubekisele phambili ukukhuthaza ukuthuthukiswa kwama-injection. Ama-injection ohlelweni lwesitimela oluvamile afakwe uhlelo lwe-hydraulic servo kanye nesici sokulawula i-elekthronikhi (i-solenoid valve). Uphethiloli ulethwa epayipini elivamile lokuphakelwa kukaphethiloli ngephampu kawoyela enengcindezi ephezulu, eqaphela ukuhlukaniswa okuphelele kwesikhathi somjovo kanye nokubala kukaphethiloli. Ingcindezi yomjovo, indawo yokuqala umjovo kanye nobude besilinda ngalinye kungalungiswa ngokuya ngezimo zokusebenza zenjini, futhi indawo yokulawula engcono kakhulu yomjovo ingalandelwa. Ingakwazi futhi ukuzuza umfutho womjovo ophezulu kakhulu futhi yenze umjovo wangaphambili wedizili.
Ukuthuthukiswa okuqhubekayo nokwenziwa okusha: Eminyakeni yamuva nje, ama-injection athuthukiswa ngokuqhubekayo futhi enziwa izinto ezintsha ngesakhiwo nokusebenza. Isibonelo, ukuze uvumelane nemithetho eqinile yokukhipha umoya futhi kuthuthukiswe ukonga kukaphethiloli, izijojo zikaphethiloli ziyaqhubeka zithuthuka ngokuya ngesakhiwo se-nozzle, izinto zokwakha, kanye nokulawula ukunemba; izinhlobo ezahlukene zama-injection kaphethiloli ezifana nohlobo lwe-valve yebhola kanye nohlobo lwe-valve yepuleti nazo zibonakale zihlangabezana nezidingo ezahlukene; i-miniaturization yama-injection kaphethiloli inomthelela ekwakhiweni okuhlangene kwezinjini; ubuchwepheshe bomjovo oqondile wengcindezi ephezulu bungathuthukisa umphumela we-atomization kanye nokusebenza kahle komlilo kaphethiloli; ukuthuthukiswa kwama-injection amaningi kaphethiloli kwenza izinjini zikwazi ukuzivumelanisa nezinhlobonhlobo zezinhlobo ezahlukene zikaphethiloli.
Ukuthuthukiswa kwama-injection kaphethiloli bekulokhu kugxile ekuthuthukiseni ukunemba komjovo, ukuthuthukisa i-atomization kaphethiloli kanye nemiphumela yokuvutha, ukunciphisa ukukhishwa kwegesi, ukuthuthukisa ukusebenza kwenjini nomnotho kaphethiloli, futhi kuhlobene eduze nentuthuko yobuchwepheshe bokulawula ugesi, isayensi yezinto ezibonakalayo, neminye imikhakha.
