Isitofu esithontsiza ioli
Iimpawu zokungaphumeleli: inaliti yamafutha eqhubekayo, ukuvaleka kwemingxuma yombhobho, ukwenzela ukuba i-atom yepetroli ingabi ne-atom, inaliti yepetroli engalinganiyo, ukuqala kakubi, ukunkqonkqoza umsebenzi, umsi wokukhupha umsi, ukunyuka kwediphozithi yekhabhoni, okukhokelela ekunciphiseni amandla e-injini, ukwanda kokusetyenziswa kwamafutha, kunye ukwanda kokunxiba.
Uphononongo lwesizathu sokungaphumeleli: (1) Umphezulu wekhowuni yokutywina yevalve yenaliti kunye nomzimba wevalufa yenaliti unxitywe kakhulu, kwaye kuvela iimpawu zegroove, ezithi zibe banzi umphezulu womphezulu wekhowuni yokuvala umphezulu weringi, ikhubaze umphezulu wekhowuni, kwaye inyuse uburhabaxa. , okubangela ukuba ioli ithontsize kwi-injector.Iidiphozithi zekhabhoni zenziwe kufutshane nomngxuma womlomo, kwaye nomngxuma wombhobho uvalekile.(2) Okukhona uphezulu uxinzelelo olushiyekileyo lombhobho wepetroli woxinzelelo oluphezulu (oko kukuthi, uxinzelelo lombhobho wesibaso woxinzelelo oluphezulu xa kungekho mafutha atofwayo phakathi kwemibhobho emibini yokutofa kwepetroli), kokukhona kubi kakhulu ukuthontsiza kwamafutha kumafutha. umlomo.Esona sizathu siphambili esichaphazela uxinzelelo olushiyekileyo kukuba ivalve yokukhupha ioyile inamaqhekeza alinganayo.Ukusilela kokuthontsiza kwe-oyile kumbhobho wenaliti ye-fuel akukho konke kumbhobho wenaliti ye-fuel, kodwa kunxulumene ngokusondeleyo nokutywinwa kwendibano yevalvu yokuhambisa amafutha.Ukunxiba okungaqhelekanga kwevalve yokuhanjiswa kweoyile kuya kubangela ukuthontsiza kwe-oyile kwi-injector.(3) Ivalve yenaliti yesitofu samafutha kunye nomphezulu wesikhokelo somzimba wevalve yenaliti inomsebenzi ombi wokutyibilika kunye nokuvalwa komsebenzi, okanye umphezulu wesikhokelo sevalve yenaliti kunye nomzimba wenaliti yenaliti igugile kakhulu, ukudibana phakathi kwevalve yenaliti. umzimba kunye nomzimba wesitofu awungqongqo, okanye ivalve yenaliti kunye nenaliti Ukutywinwa komphezulu we-tapered womzimba wevalvu ukhuselwa bubumdaka obungoomatshini, kwaye ukuba ayivalwanga ngokuqinileyo, iya kubangela ukuba isitofu sefutha sithontsize ioyile.
