New Injector Nozzle Dlla149p1805 0433172099 for Fuel Injector 0445120168 0445120405 0445120406

(1) Mushure mejekiseni guru rekutanga-jekiseni, pombi yepombi yemafuta inoramba ichifamba ichidzika, zvichiita kuti mafuta emafuta ari mukamuri yemafuta awedzere kusimuka nekukurumidza. Kana kudzvanywa kwemafuta kuchikwira kuve kwakakwira kupfuura pre-jekiseni mafuta pressure (30MPa), jekiseni vharafu inosimuka uye jekiseni guru rinotanga. Nekuti kudzvanywa kwemafuta emafuta mukamuri yekudzvanya kwemafuta kunokwira zvakanyanya, kudzvanywa kwemafuta mukamuri yekudzvanya kwemafuta kucharamba kuchikwira kusvika pa205MPa.
(2) Iyo huru jekiseni yemafuta inopera. Kana iyo yemagetsi control system yamira kupa simba kune electromagnetic control valve, iyo valve yetsono ye electromagnetic control valve inofamba ichienda kurudyi pasi pechiito chekudzoka chitubu che electromagnetic control tsono valve, uye inobatanidza yakakwira-kudzvanywa mafuta kamuri uye low-pressure oil passage. Panguva ino, mafuta ari mukamuri yekudzvanya yemafuta anoyerera achienda kune yakaderera-kudzvanywa kwemafuta nzira kuburikidza nemagetsi ekudzora vharafu, kudzvanywa kwemafuta mukamuri-kudzvanywa kwemafuta kunodonha, iyo jekiseni jekiseni revhavha rinogadzika pasi pechiito che kudzoka chitubu chemafuta jekiseni vharafu, uye yekubatsira plunger iri mune jekiseni mamiriro. Pasi pechiito chekudzoka kwechitubu chevhavha yetsono yemafuta, nzira yemafuta pakati pe-high-pressure mafuta chamber uye chitubu chekudzoka chejekiseni chevhavhavha yakavharwa, uye jekiseni guru rinopera.
(3) Oiri inopinda mukamuri yemafuta anodzvanywa. Kana chikamu chinodzika chemacam chinosangana nerocker arm, pombi yemafuta plunger inokwira kumusoro pasi pechiito chekudzoka kwechitubu chepombi yepombi yepombi, uye kamuri yemafuta yepamusoro-soro inogadzira vacuum nekuda kwekuwedzera kwehuwandu. Panguva ino, mafuta ari muchikamu chepasi-anotsikirira oiri (yakabatana nepombi yekupinda nemafuta) inoyerera ichienda kukamuri yekudzvanya mafuta kuburikidza nemagetsi emagetsi ekudzora vharafu kusvika iyo yakanyanya-kudzvanywa kamuri yemafuta yazadzwa, kuitira kugadzirira jekiseni rinotevera remafuta.
