Kuongororwa kwemafuta emagetsi
Kana mamiriro achibvumidza, jekiseni remafuta rinogona kuiswa zvakananga pabhenji rekuongorora jekiseni rekuongorora bvunzo zvinoenderana nezvinodiwa. Mukushaikwa kwebhenji rekuongorora jekiseni remafuta, gadziriso yacho inogona kutariswa zvakananga painjini yedhiziri, iyo inogona kuitwa nenzira mbiri dzinotevera:
(1) Chekutanga gadzira jekiseni remafuta rakajairwa (jekiseni remafuta rine jekiseni remafuta uye mhando yekupfapfaidza inotariswa nekugadziridzwa) uye yekubatanidza nzira nhatu, iise papombi jekiseni remafuta (pombi jekiseni remafuta rinofanira kupa mafuta kazhinji) iyo yakabatana yevhavha yekubuda kwemafuta, ita kuongorora kwekuenzanisa. Isa iyo throttle panzvimbo yepamusoro yemafuta ekupa, depressurize injini yedhiziri, tenderedza crankshaft nekumhanya kwe100 ~ 200 r/min, uye enzanisa yakajairwa jekiseni remafuta neyakaedzwa mafuta jekiseni.
Kana iyo yakajairwa jekiseni remafuta uye yakaedzwa mafuta jekiseni ichibaya mafuta panguva imwe chete, iyo atomization yakanaka, ruzha rwejekiseni remafuta rakatsetseka, uye hapana kubuda kwemafuta uye kudonha, zvinoreva kuti jekiseni remafuta uye kunaka kweatomu. yakaedzwa mafuta injector vanokwanisa. Kana jekiseni rakaongororwa rikabaya oiri pamberi kana mushure mejekiseni yakajairwa, zvinoreva kuti jekiseni rejekiseni rakatariswa rakaderera kana rakakwira, uye rinofanirwa kugadziriswa nekupinza mukati kana kumashure kudzvanya regulating screw, kudzamara iyo yakaongororwa mafuta jekiseni ndiyo. zvakafanana neyakajairika. Kana majekiseni maviri emafuta achibaya mafuta panguva imwe chete, uye injector yemafuta yakaonekwa ine atomization yakashata, matanda emafuta kana madonhwe emafuta, zvinoreva kuti pane dambudziko neiyo yakaonekwa tsono yekubatanidza valve, uye inoda kugadziriswa kana kutsiviwa.
