● Yehlisa amathuba okubila kwamafutha
● Qinisekisa ukuba imoto ibaleka kakuhle
● Ivumela isithuthi ukuba siqalise
Impompo yamafutha yenye yezinto ezisisiseko zenkqubo yokutofa amafutha kwisithuthi sokutofa.Impompo yamafutha ingaphakathi kwitanki yamafutha yesithuthi.Umsebenzi kukufunxa i-fuel kwi-tank ye-fuel, ukuyicinezela kwaye uyithuthe kumbhobho wokubonelela ngamafutha, kwaye umise uxinzelelo oluthile lwe-fuel kunye nomlawuli we-fuel pressure.
Ipompo yepetroli iqulethe i-motor yombane, i-pressure limiter kunye ne-valve yokukhangela.Injini yombane eneneni isebenza kwi-oyile yamafutha kwindawo yempompo yeoli.Ungakhathazeki, kuba akukho nto eqokobheni yokutshisa umlilo.Ioyile yesibaso iyathambisa kwaye ipholisa imotor yamafutha.Ivalve yokukhangela ifakwe kwindawo yokukhupha ioli.I-limiter yoxinzelelo ibekwe kwicala loxinzelelo lwendlu yempompo kunye nomjelo wokungena kwi-oyile.Impompo yamafutha isebenza ngexesha lokuqalisa kunye nokusebenza kwenjini.Ukuba i-injini iyayeka ngelixa i-ignition switch isavuliwe, imodyuli yokulawula ye-HFM-SFI ivala amandla kwimpompo yamafutha ukuphepha ukuvutha ngengozi.
Impompo yamafutha luhlobo lwempompo esetyenziswa kwinkqubo yokubonelela ngeoyile.Isetyenziselwa ukunqoba ukunyanzeliswa kwe-hydraulic ye-filter ye-fuel kunye nokuzinzisa ubungakanani bepetroli enikezelwa kwimpompo yoxinzelelo oluphezulu xa uxinzelelo lwe-hydraulic lwefayile luphakanyiswa ngenxa yokungcola.Izinga lokuhamba kwempompo yepetroli kufuneka ibe ubuncinane ngamaxesha angama-2 + 3.5 obuninzi bokunikezelwa kwamafutha enjini ukuze kuqinisekiswe ukuba ipompo yoxinzelelo oluphezulu inokusebenza ngokuzinzileyo kwimeko yokucoca okungcolileyo kunye nokuchasana okuphezulu.
Ipompo yepetroli iqhutywa yi-high-pressure pump shaft okanye injini.Kwezinye iinkqubo, impompo eqhutywa ngombane isetyenziselwa ukuvelisa impompo encedisayo.Ipompo yamafutha inohlobo lwepiston, uhlobo lwe-diaphragm, uhlobo lwegiya, uhlobo lwe-rotor-vane kunye nezinye iintlobo ezahlukeneyo.
