IValve yoLawulo lweSiporo esiQhelekileyo seSeti iNdibano F00VC01037 kunye neNxalenye ye-Injector esecaleni ye-Injector 0445110112 0445110187

Iindlela yokuhlola indibano yevalve yenaliti yesitofu samafutha

(1) Uvavanyo lokuqina kwentamo. Sebenzisa ioli edibeneyo okanye i-20 # ioli ye-diesel elula, kwaye usebenzise indlela yokunciphisa ukuphumeza kwibhentshi ekhethekileyo yovavanyo. Ngexesha lovavanyo, sebenzisa impompo yesandla ukuphakamisa uxinzelelo kwi-23-24 MPa, kwaye ulinganise ixesha loxinzelelo lwehla ukusuka kwi-20 MPa ukuya kwi-18 MPa. Iziphumo zovavanyo ziyahambelana Imveliso eqhelekileyo kufuneka ithelekiswe noluhlu olufunekayo.

(2) Uvavanyo lokutywinwa kwesitulo. Sebenzisa i-oyile ye-diesel engama-20 # kwibhentshi yovavanyo ene-accumulator yoxinzelelo, lungisa kuqala uxinzelelo lwenaliti yamafutha kuxinzelelo oluchaziweyo lwe-12.5 MPa, kwaye wandise uxinzelelo lwe-oyile nge-0.1 MPa rhoqo nge-3 ukuya kwi-5 ngokulinganayo ukuya ekuqaleni kokutofa. Ioyile, jonga umgangatho wokutywinwa, ukuvuza okuncinci kweoyile kuvunyelwe, kwaye ububanzi bokuvuza kweoyile abukho ngaphezu kwe-5 mm (isihlalo kunye nomphezulu akusiyo omnye komnye) okanye i-3 mm ububanzi (isihlalo kunye nomgangatho wokutywina) umphezulu uyasila). Kodwa hayi kwimilo engqukuva engqukuva.

(3) Uvavanyo lokutshiza. Sebenzisa i-20# ye-oyile yedizili ekhanyayo kwibhentshi yovavanyo, hlengahlengisa uxinzelelo lwenaliti ye-fuel ukuya kwi-12.5 MPa, kwaye wenze uvavanyo lokutshiza ngenani lezitofu ezingama-40-80 amaxesha /imiz. 

Umgangatho wokutshiza kufuneka uhlangabezane nezi mfuno zilandelayo:

①I-fuel injected kufuneka i-atomized, kwaye akufuneki kubekho amaqhekeza e-oyile yokutshiza kunye nokugxininiswa kokungalingani kwendawo kunokubonwa ngeso lenyama.

②Ukuqala nokuphela kokutshiza kufuneka kucace, kwaye isandi kufuneka sibe bukhali.

③Ngaphambi kokuqala kokutshiza kwaye emva kokuphela kokutshiza, ukuvuza kweoli akuvumelekanga kumngxuma wokutshiza, kodwa umswakama uvumelekile.

(4) Jonga i-engile yokutshiza. Jonga ngeso lenyama, thelekisa i-angle yokutshiza phantsi koxinzelelo lwenaliti yamafutha esetyenziswa kwi-injini yedizili kunye nesampulu, kwaye ukutenxa phakathi komgca osembindini we-engile yokutshiza ye-injector yamafutha kunye nomgca osembindini we-injector yamafutha awukho mkhulu. ngaphandle kwe4°30'. I-angle yekhowuni yokutshiza ibonwa ngaphakathi kwe-100 mm.

(5) Uvavanyo lokutyibilika. Coca ngononophelo kwaye uthambise iindawo ngeoli yedizili ehluziweyo. Xa ivalve yenaliti ikwi-45° kwindawo ethe tye, tsala ivalve yenaliti kumzimba wevalve yenaliti nge-1/3 yobude bayo. Yijike kuyo nayiphi na indawo kwaye uyiyeke. Ubunzima ngokwawo buslayida ngokukhululekileyo ngaphandle kwesithintelo.
