Fuel Injector Matambudziko uye Troubleshooting
Majekiseni etsono… Muinjini dzemazuva ano, majekiseni etsono anoshandiswa kunyanya muinjini dzepeturu, uye kunyanya muGDI (jekiseni rakananga gasi). Sezvatakakurukura muzvinyorwa zvakapfuura, GDI inoisa atomize uye inoisa mafuta mukamuri rinopisa, pamusoro pepiston. Nekuda kwekumisikidzwa kwepintal, kabhoni deposits fomu papintal cone, iyo inovhiringidza maitiro ekupfapfaidza. Sezvo kuvaka kunowedzera, kugoverwa kusina kuenzana kwejeti kunoguma nekupisa kusina kuenzana kunozokura kuita kushata kana kurira ... uye pamwe kunogona kugadzira nzvimbo inopisa papiston kana, muzviitiko zvakanyanya, kunyungudutsa gomba mupiston. Nehurombo, mamiriro aya anogadziriswa (zvichida) nekushandisa "yekuchenesa" mafuta ekuwedzera, nemuchina kupepeta jekiseni system nemichina yakakosha uye yakagadziriswa mhinduro, kana kubvisa majekiseni ebasa kana kutsiva.
Multi-hole jekiseni ndiwo majekiseni makuru anoshandiswa muinjini dzedhiziri. Dambudziko guru rinotarisana nejini yemazuva ano yedhiziri nhasi kunaka uye kuchena kwemafuta. Sezvambotaurwa, maCommon Rail masisitimu emazuva ano anosvika kumanikidziro anosvika 30,000 psi. Kuti uwane kudzvinyirirwa kwakanyanya kwakadaro, kushivirira kwemukati kwakanyanya kusimba kupfuura mushanduro dzakapfuura dzemanozzles (mamwe kushivirira anotenderera ari 2 microns). Sezvo mafuta ari ega ega mafuta ejekiseni uye naizvozvo majekiseni, mafuta akachena anodiwa. Kunyange kana iwe ukashandura mafiritsi panguva yakakodzera, chikamu chechinetso ndechekupa mafuta ... zvinenge zvose matangi epasi ane tsvina (tsvina, mvura kana algae) yakagadzika pasi petangi. HAUFANIRI kuzora mafuta kana ukaona rori yemafuta ichiunza mafuta (nekuti kumhanya kwefuel iri kuuya kunokanganisa zviri mutangi) - dambudziko nderekuti kombi inogona kunge ichangobuda iwe usina kuiona!!
Mvura mumafuta idambudziko guru sezvo mvura inosimudza nzvimbo yekubikira yemafuta, asi zvakatonyanya inokanganisa kukora kwemafuta ayo akakosha...kunyanya kubva sarufa yaivepo semafuta yakabviswa nemutemo weEPA. . Mvura iri muhuturu ndiyo inonyanya kukonzera jekiseni tip kukundikana. Kana iwe uine matangi ako epamusoro ekuchengetedza pasi, iyo condensate inoumba mukati metangi iri pamusoro pemutsetse wemafuta (kunyanya mukudziya kuri kukurumidza kuchinja) inoumba madonhwe uye yakananga pasi petangi. Kuchengeta matangi ekuchengetedza aya akazara kunoderedza dambudziko iri… Kubatanidzazve tangi yekuchengetera kunokurudzirwa kana uine chikafu chegiravhiti pasi petangi.
Tsvina kana algae mafuta idambudziko zvakare neazvino high pressure system. Iwe unogona kazhinji kutaurira kana kusvibiswa idambudziko pakuongorora ... mapikicha mashomanana akabatanidzwa kune tsamba.
Rimwe dambudziko ratinosangana naro kuNorth America imhando chaiyo kana kupisa kwemafuta pachayo. Nhamba yecetane chiyero cheizvi. Diesel mafuta ane zvinopfuura 100 zvikamu zvinokanganisa nhamba yecetane (iyo yakafanana neyo octane nhamba yepetroli).
MuNorth America, nhamba shoma yecetane ndeye 40 ... muEurope, zvishoma ndeye 51. Yakaipisisa kupfuura inonzwika nokuti ikero ye logarithmic. Chinhu chimwe chete chinogona kuitwa kushandisa chiwedzere kuvandudza zvese nhamba yecetane uye lubricity. Anowanikwa zviri nyore…ingogara kure nevaya vanonwa doro…anofanira kungoshandiswa senzira yekupedzisira kana tambo yemafuta yakaomeswa nechando kana parafini iripo. Doro rinoparadza mafuta ehuni, zvichiita kuti pombi kana majekiseni abate.
