Ongororo Yezvakajairwa Zvikanganiso zveFuel Injector
Iyo jekiseni yemafuta ndeimwe yezvikamu zvitatu zvakanyatsojeka zveinjini yedhiziri system, uye iko kuenderana kwakakwira. Kana ikasashandiswa uye kuchengetedzwa nemazvo, inokonzeresa yakakomba madhipoziti mujekiseni remafuta, zvichiita kuti ripise kana kunamira, uye jekiseni remafuta rakawandisa kana rakaderera, nokudaro zvichikanganisa kushanda kwakajairwa kweinjini yedhiziri. Nokudaro, mukushandiswa nekugadzirisa motokari, jekiseni remafuta rinofanira kukosheswa zvikuru kuitira kuti jekiseni yemafuta igare yakachengetwa mune yakajairika tekinoroji mamiriro.
1.1 Kupfeka jekiseni
Injector (pintle type) Nhengo dzinowanzo pfeka ndeidzi: kuvharisa pamusoro pekoni, pintle uye chikamu chegwara. Chikonzero chekupfeka zvisina kujairika kwezvikamu izvi zvinonyanya kukonzerwa nekusachena mumafuta edhiziri. Kupfeka kweiyo yekuvharisa koni pamusoro pejekiseni (tsono vharuvhu cone pamusoro uye tsono vharafu muviri cone pamusoro) kuchaita kuti mafuta adonhe kubva mujekiseni nozzle, kugadzira kabhoni deposits, uye mumatambudziko akaomarara, gomba remhuno rinovharika. Kupfeka kwechikamu chinofananidzira chepini uye gomba rejekiseni kuchawedzera dhayamita yegomba rejekiseni uye kushandura kona yejekiseni, zvichikonzera kushomeka kweatomu yemafuta. Kupfeka kwechikamu chegwaro kunowedzera kudzoka kwemafuta kwejekiseni, kunoderedza mafuta, kunoderedza kudzvanywa kwejekiseni, uye kunonotsa nguva yejekiseni.
tsono vharafu yakanamatira
Pane zvikonzero zvina zvinogona kukonzera vharafu yetsono: 1. Kuiswa kusina kunaka kwejekiseni remafuta. Iyo gasket kumucheto kwezasi kwejekitori yemafuta igasket yemhangura. Inokonzerwa nekushisa kwepamusoro, valve yetsono inoputirwa uye yakanamatira. 2 Diesel ine tsvina kana hunyoro hwakanyanya. 3. Nzvimbo yekoni yevhavha yetsono yeinjector yemafuta haina kuvharwa zvakasimba, uye mafuta edhiziri anoputika kusvika kumagumo ejojo ​​yemafuta achaita kuti jekiseni yemafuta inopisa kana ichipisa. 4. Injini yedhiziri inoremerwa kwenguva yakareba, kana nguva yekupa mafuta yakakurumidza kana kuti yakanyanyisa, uye mafuta edizeli haana kupiswa zvachose kuti abudise carbon deposits, zvichiita kuti kupisa kwakashata kweinjector uye jamming. Kana vharafu yetsono yakanamatira kana iri munzvimbo yakashama, mafuta edhiziri akapfapfaidzwa nejekiseni remafuta haagone kupiswa uye haagone kupiswa zvachose. Kana iyo valve yetsono yakanamatira munzvimbo yakavharwa, zvisinei kuti yakakwira sei mafuta ekumanikidza epombi jekiseni yepombi, iyo valve yetsono haigone kuvhurwa, uye cylinder haigone kushanda.
