Izvo zvikamu zvikuru zvehutori system zvine yakakwirira chaiyo, nyore kukundikana mubasa, basa redhiziri mafuta systemyakanaka kana yakaipa, ichakanganisa zvakananga simba nehupfumi hweinjini yedhiziri, saka basa rekuchengetedza uye rekuchengetedza nderokuwedzera hupenyu hwebasa rezvikamu zvikuru zvehuni system, kuderedza kukundikana kwehuwandu hunokosha hunobatanidza, ndeyekuvimbisa kushanda kwakajairwa kwekiyi injini yedhiziri.
Iko kushandiswa kwakaringana uye kuchengetedza kwemafuta system ndiyo kiyi yekuve nechokwadi chekushanda kwakajairika kweinjini yedhiziri. Diesel furo kuchena ndiro dambudziko rakakosha mukushandiswa nekuchengetedza masisitimu emafuta.
(1) Kushandisa uye kugadzirisa tangi yemafuta. Tangi yemafuta inofanira kuzadzwa nemafuta nguva nenguva, uye sefa yefiriji yechiteshi chemafuta inofanira kucheneswa nguva nenguva. Gomba remhepo rechiteshi chekuisa mafuta rinofanira kuchengetedzwa rakachena uye risina kuvharika kudzivirira vacuum mutangi uye kusakwana kwemafuta. Mukati metangi inofanira kucheneswa nguva dzose, uye chikamu chepasi chetangi chinofanirwa kuvhurwa nguva nenguva kuti chibudise tsvina nemvura inonaya.
(2) Kucheneswa kwemafuta sefa. Munguva yekushandiswa kweinjini yedhiziri, tsvina uye tsvina mumafuta edhiziri inoungana pamusoro peiyo sefa musimboti uye inoisa kuzasi kweimba, kana isina kubviswa nenguva, inokonzeresa kuvharika kweiyo sefa musimboti. Naizvozvo, sefa yemafuta inofanira kucheneswa nguva dzose maererano nemirayiridzo panguva yekushandiswa kweinjini yedhiziri.
(3) Kugadziriswa kwepombi jekiseni remafuta. Panguva yekushandiswa kweinjini yedhiziri, mwero wemafuta ekuzora mupombi yejekiseni unofanirwa kuongororwa nguva nenguva zvichienderana nemirairo, uye mafuta ekuzora anofanirwa kutsiviwa nguva nenguva kuti ave nechokwadi chekuzora zvakajairika.
(4) Gavhuna akagadziridzwa nomuedzo wefekitari, ane chisimbiso chomutobvu, uye haakwanisi kuparadzaniswa nyore nyore. Gavhuna anofanirwa kutarisa huwandu hwemafuta ekuzora nguva nenguva uye oazadza kana kutsiva nenguva. Iyo oiri level cheki plug (kana chiyero chemafuta) inopiwa pane gavhuna imba, uye kureba kwemafuta ari gavhuna kunofanirwa kugara kuchichengetwa zvinoenderana nezvinodiwa nebhuku.
(5) Fuel injector kukanganisa kuongorora uye kugadzirisa. Mushure mekunge jekiseni remafuta rakundikana, zvinotevera zvisina kujairika zviitiko zvinowanzoitika:
1. Utsi hunopedza simba.
2. Simba rehumburumbira rimwe nerimwe harina kuenzana, uye kudengenyeka kunoitika.
3. Kuderera kwesimba.
Kuti uwane injector yakashata yemafuta, inogona kuongororwa sezvinotevera; Kutanga ita kuti injini yedhiziri imhanye nekumhanya kwakaderera, uye wozomisa jekiseni rejekiseni resilinda rimwe nerimwe, uye teerera kune shanduko yemamiriro ekushanda eiyo.injini yedhiziri. Kana jekiseni recylinder ramiswa,
Kana iyo inopera isingachabudisi utsi hutema, injini yedhiziri inochinja zvishoma kana isingachinji, inoratidza kuti cylinder injector yakashata; Kana injini yedhiziri ikashanda asi ikasagadzikana, kumhanya kunodzikira zvakanyanya, uye yava kuda kumira, jekiseni recylinder rinoshanda zvakajairika.
Mafuta majekiseni anowanikwa mu corrector. Kana zvinotevera zvikaitika, zvinoratidza kuti jekiseni remafuta rakashata.
① Jekiseni pressure yakaderera pane yakataurwa kukosha.
② Kupfapfaidza mafuta haaite atomize, mune iri pachena inoenderera kuyerera kwemafuta.
③ Porous injector, yega yega mafuta bundle haina symmetrical, kureba hakuna kufanana.
④ Injector inodonha mafuta.
⑤ Gomba rekupfapfaidza rakavharika, hapana mafuta anogadzirwa kana mafuta anopfapfaidzwa kuita dendritic shape. Kana matambudziko ari pamusoro akawanikwa, anofanira kugadziriswa kana kuchinjwa.
