Umsebenzi woMbhobho we-oyile namanzi:
Kukuvumela i-oyile egqithisileyo ukuba ibuyele kwitanki yamafutha ukunciphisa ukusetyenziswa kwe-oyile. Ayizizo zonke iimoto ezinethumbu lokubuya.
Isihluzo somgca wokubuyisela i-oyile sifakwe kumgca wokubuya kwe-oyile we-hydraulic system. Isetyenziselwa ukuhluza umgubo wentsimbi ogugileyo kunye nokungcola kwerabha kumalungu e-oyile, ukuze i-oyile equkuqelayo ibuyele kwitanki yeoli igcinwe icocekile.
Into yokucoca isihluzo sisebenzisa izixhobo zokucoca iikhemikhali, ezinezibonelelo zokuchaneka okuphezulu kokucoca, ukungenwa kwe-oyile enkulu, ilahleko encinci yoxinzelelo lwasekuqaleni, kunye nomthamo omkhulu wokubamba ubumdaka, kwaye ixhotyiswe nge-transmitter yoxinzelelo olwahlukileyo kunye nevalve edlulayo.
Xa into yokucoca ivaliwe kude kube umahluko woxinzelelo phakathi kwendawo yokungena kunye ne-outlet yi-0.35MPa, uphawu lokutshintsha lukhutshwa. Ngeli xesha, into yokucoca kufuneka icocwe okanye itshintshwe. Inkqubo yoKhuselo. Isihluzi sisetyenziswa kakhulu koomatshini abanzima, oomatshini basemigodini, oomatshini besinyithi kunye nezinye iinkqubo zamanzi.
Ngoku iimoto ezininzi zinemibhobho yokubuyisela ioyile. Emva kokuba impompo yamafutha inikezela nge-fuel kwi-injini, uxinzelelo oluthile luyenziwa. Ngaphandle konikezelo oluqhelekileyo lwenaliti ye-nozzle ye-fuel, i-fuel eseleyo ibuyiselwa kwi-tank ye-fuel ngokusebenzisa i-oyile yokubuyisela umgca, kwaye ngokuqinisekileyo kukho i-petroli engaphezulu eqokelelwe yi-carbon canister. . Umbhobho wokubuyisela amafutha unokubuyisela i-oyile engaphezulu kwi-tank ye-fuel, enokunciphisa uxinzelelo lwepetroli kunye nokunciphisa ukusetyenziswa kwepetroli.
Iinkqubo zokubonelela nge-diesel fuel ngokubanzi zibonelelwa ngemigca emithathu yokubuya, kwaye ezinye iinkqubo zokubonelela nge-diesel fuel zibonelelwa ngemigca emibini kuphela yokubuyisela, kwaye akukho mgca wokubuya ovela kwisihluzo samafutha ukuya kwitanki yamafutha.
Buyisela umgca kwisihluzo samafutha
Xa i-fuel pressure enikezelwa yi-fuel pump idlula i-100 ~ 150 kPa, i-valve yokuphuphuma kumgca wokubuyela kwisihlunu se-fuel ivula, kwaye i-fuel engaphezulu ibuyele kwi-tank ye-fuel ngomgca wokubuyela.
Umgca wokubuyisela i-oyile kwimpompo yokutofa kwamafutha
Ekubeni umthamo wokuhanjiswa kwepetroli wempompo yepetroli uphindwe kabini ukuya kwesithathu amandla okubonelela ngamafutha epompo yokutofa kwe-fuel phantsi kweemeko zokulinganisa, i-fuel engaphezulu ibuyela kwitanki yamafutha ngombhobho wokubuyisela amafutha.
Umgca wokubuyisela kwi-injector
Ngexesha lokusebenza kwe-injector, inani elincinci kakhulu lepetroli liya kuvuza kwivalve yenaliti kunye nomgangatho wokukhwelana womzimba wevalufa yenaliti, onokudlala indima yokuthambisa, ukunqanda ukuqokelelana okugqithisileyo kunye noxinzelelo lwangasemva lwevalve yenaliti. phezulu kakhulu kunye nokusilela komsebenzi. Le nxalenye yepetroli ifakwe kwi-filter fuel okanye itanki ye-fuel ngokusebenzisa i-bolt engenanto kunye nombhobho wokubuyisela.
Ukungaphumeleli kokugweba:
Kwiinjini zeemoto, umbhobho wokubuyisela ioli uyinxalenye engabonakaliyo, kodwa idlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuqhelekileyo kwenjini. Ukulungelelaniswa kombhobho wokubuyisela ioli kwimoto yinto ekhethekileyo. Ukuba umbhobho wokubuyisela i-oyile uyavuza okanye uvalekile, oko kuya kubangela ukusilela okwahlukeneyo okungalindelekanga. Umbhobho wokubuyisela i-oyile "yifestile" yokulungisa ingxaki ye-injini. Ngombhobho wokubuyisela i-oyile, unokukhangela ngobuchule kwaye ugwebe ukusilela kwe-injini ezininzi. Indlela yokuhlola eyisiseko yile ilandelayo: Vula umbhobho wokubuyisela ioli ukujonga kwaye ukhangele ngokukhawuleza imeko yokusebenza kwenkqubo yamafutha. Ingaba uxinzelelo lwamafutha lwenkqubo yamafutha enjini yokutofa luqhelekile. Ngokungabikho kwegeyiji yoxinzelelo lwamafutha okanye igeyiji yoxinzelelo lwepetroli enobunzima bokufikelela kumgca wamafutha, inokugwetywa ngokungathanga ngqo ngokujonga imeko yokubuyisela ioyile yombhobho weoyile. Indlela ethile (thatha i-Mazda Protégé imoto njengomzekelo): qhawula umbhobho wokubuyisela i-oyile, emva koko uqalise injini kwaye uqaphele ukubuya kwe-oyile. Ukuba ukubuya kweoyile kungxamisekile, uxinzelelo lwamafutha luyinto eqhelekileyo; ukuba ukubuyiswa kweoli kubuthathaka okanye akukho kubuyiselwa kweoli, kubonisa ukuba uxinzelelo lwe-fuel alunelanga, kwaye kufuneka uhlolisise kwaye ulungise iimpompo zamafutha ombane, izilawuli zoxinzelelo lwamafutha kunye nezinye iindawo. Amafutha aphuma kumbhobho weoyile angeniswa kwisikhongozeli ukuthintela ukungcoliseka kwendalo kunye nomlilo).
