Disassembly Sequence uye Maintenance Method yeFuel Injector yeDiesel Engine

Iyo injector yemafuta zvakare chikamu chakakosha chemafuta ekupa system yeinjini yedhiziri.Basa rayo nderekupfapfaidza mafuta edhiziri epamusoro-soro kubva papombi yejekiseni yemafuta mukamuri yekupisa muchimiro chemhute, uye kugadzira musanganiswa wakanaka unopisa nemhepo yakamanikidzwa mukamuri yekupisa.Iyo jekiseni yemafuta haingotarise mhando yekupfapfaidza yedhiziri, kubatirana pakati pedanda remafuta nekamuri yekupisa, asi zvakare inokanganisa majekiseni emafuta epamberi, nguva yejekiseni yemafuta uye jekiseni remafuta, izvo zvine chekuita nekuita kwe injini.Naizvozvo, zvinodikanwa zvekutanga zvebasa rejekiseni ndezvi: imwe jekiseni kudzvanywa uye renji, pamwe neakakodzera koni yekupfapfaidza kona, uye inowirirana nechimiro chekamuri yekupisa.Uye zvakare, jekiseni remafuta rinogona kumiswa nekukurumidza pakupera kwejekiseni remafuta pasina kudonha mafuta.

imwe: kuchengetedza jekiseni remafuta

Mushure mekuchenesa zvikamu zvejekiseni, kana chimwe chezvinhu zvinotevera zvisingawanzoitiki zvakawanikwa, zvinofanira kugadziriswa kana kuchinjwa.Kana magumo emuviri wejekiseni akasanganiswa nemuviri wevharuvhu yetsono paine kukuvara kudiki, vhomora mapini ekumisikidza maviri wokuya ndiro Gaya pairi.Chenjera kuti usabata nzvimbo ine hutsinye kana uchiburitsa pini yekumisikidza.
② Kana iyo nzvimbo yekumanikidza inodzora chitubu chejekitori yemafuta yakakweshwa, yakagochwa kana kuremara zvachose, inofanira kutsiviwa.
③ Iyo kabhoni inoisa mukati mefudzi blade uye gomba madziro einjector tight cap inofanira kubviswa zvachose.
④ Iyo dhayamita chikamu chemafuta jekiseni nozzle musangano yakapfekwa, uye inofanirwa kutsiviwa kana paine yakakomba kubuda kwemafuta.
⑤ Kana maburi emhuno aine hurema hwakadai sekupfeka uye kuwedzera, ayo anokanganisa kunaka kwekupfapfaidza anofanira kutsiviwa.
⑥ Kana chigaro chekuisa chisimbiso chevharuvhu yetsono nemuviri wetsono yevharuvhu isina kunyanya kupfekwa, inogona kugadziriswa nekukuya pamwe chete nealuminium abrasive paste.Paunenge uchikuya mumwe nemumwe, usashandise simba rakawandisa, uye nzvimbo yekuisa chisimbiso inogona kusvika kune yunifomu uye kwete yakawandisa yekuisa chisimbiso bhandi.
⑦ Nekuda kwekudzokera shure kwegasi mu cylinder injini ye diesel kana kupindira kwekusvibiswa kwakanaka mujekitari yemafuta, valve yetsono inova yakasviba kana yakanamatira.Mushure mekuchenesa uye kutsvakurudza pamwe chete, inogona kushandiswa zvakare kana kutsiviwa maererano nekuoma kwemamiriro acho ezvinhu.

mbiri: Nyaya dzinoda kutariswa mukusangana kwejekiseni

① Munguva yese yekusangana kwemafuta injector maitiro, zvikamu zvinofanirwa kuchengetwa zvakachena, kunyanya zvisimbiso zvemafuta jekiseni gungano pacharo uye kumagumo kwemuviri wejekiseni.Kunyangwe marara madiki neguruva zvinogona kukonzera kutsvedza kuvharika uye Kuiswa chisimbiso kwenzvimbo yekubata hakuna kunaka.Iyo scapular pamusoro apo iyo yakasimba cap yeinjector yemafuta inosangana nejekitori yemafuta inofanirwa kuve yakatsetseka uye yakati sandarara, uye hapana kabhoni deposits kana maburrs anotenderwa, zvikasadaro zvinokanganisa coaxiality uye verticality yekumisikidzwa kwegungano rejekiseni remafuta, nekudaro zvichikonzera kutsvedza kwejekiseni remafuta kwakashata.
② Paunenge uchiunganidza, tanga kupeta mupombi inopinza pombi yakabatana iyo yakafanoshongedzerwa neoiri sefa yepakati, uye dzvanya gasket remhangura kuti uwane chisimbiso chakasimba pasina kubuda kwemafuta.Wobva waisa pressure inodzora chitubu uye ejector rod mukati meinjector body, screw in pressure regulating screw kusvika yangobata pressure inodzora chitubu, wobva wadzvanya pane pressure inodzora nati.
③ Chengetedza jekiseni remafuta wakatarisa pasi pabhenji vise, isa jekiseni remafuta, uye simbisa chivharo.Iyo torque yekusimbisa ndeye 59-78 Nm (6-8kgf.m).Yakawandisa torque inokonzeresa deformation yemuviri wetsono, ichikanganisa kutsvedza kwevharuvhu yetsono, uye yakawandisa torque inokonzeresa kubuda kweoiri.
④ Iyo yakaunganidzwa mafuta jekiseni jekiseni inofanira kuedzwa pabhenji rekuyedza yekuisa chisimbiso nekupfapfaidza, uye kuvhura kudzvanywa kwejekiseni remafuta kunofanirwa kugadziridzwa.
