Umgangatho oPhezulu weValve yoLawulo lukaLoliwe oluPhakamileyo lweSeti iNdibano F00RJ01334 ye-Diesel Injector 0445120047 0445120091 0445120093

Iivalvu ze-Solenoid okanye ze-piezoelectric zenza ukuba kubekho ulawulo olululo lwe-elektroniki ngaphezu kwexesha lokutofa amafutha kunye nobungakanani, kunye noxinzelelo oluphezulu olwenziwa bubuchwephesha obuqhelekileyo bukaloliwe bubonelela nge-atomisation engcono yamafutha. Ukunciphisa ingxolo ye-injini, iyunithi yokulawula i-injini ye-elektroniki inokutofa ixabiso elincinci ledizili ngaphambi nje kwesiganeko esiphambili sokutofa (isitofu "somqhubi"), ngaloo ndlela inciphisa ukuqhuma kwayo kunye nokungcangcazela, kunye nokwandisa ixesha lokutofa kunye nobuninzi bokuhluka komgangatho wamafutha. , ukuqala okubandayo, njalo njalo. Ezinye iisistim zamafutha kaloliwe aphucukileyo zenza iinaliti ezintlanu ngestrowuthi nganye.

Ii-injini zikaloliwe eziqhelekileyo zifuna ixesha elifutshane kakhulu ukuya kokungabikho kwexesha lokufudumeza, ngokuxhomekeke kubushushu be-ambient, kwaye zivelise ingxolo ephantsi ye-injini kunye nokukhutshwa kwe-injini kuneenkqubo ezindala.

Iinjini zedizili ngokwembali zisebenzisa iindlela ezahlukeneyo zokutofa kwamafutha. Iintlobo ezimbini eziqhelekileyo ziquka inkqubo ye-unit-injection kunye ne-distributor / inline-pump systems. Ngelixa ezi nkqubo zindala zibonelela ngobungakanani bepetroli obuchanekileyo kunye nolawulo lwexesha lokutofa, zithintelwa zizinto ezininzi:

Ziqhutywa cam, kwaye uxinzelelo lwenaliti lulingana nesantya senjini. Oku kuthetha ukuba olona xinzelelo luphezulu lwenaliti lunokufikelelwa kuphela ngesantya esiphezulu se-injini kwaye olona xinzelelo luphezulu lwenaliti olufikelelekayo luyehla njengoko isantya senjini sihla. Obu budlelwane buyinyaniso kuzo zonke iimpompo, kwanazo zisetyenziswa kwiinkqubo zikaloliwe eziqhelekileyo. Ngeyunithi okanye iinkqubo zokusabalalisa, uxinzelelo lwe-injection luboshwe ngokukhawuleza kwisiganeko sokupompa esisodwa ngaphandle kwe-accumulator, ngoko ke ubudlelwane buvelele kwaye bunzima.

Zilinganiselwe kwinani kunye nexesha leziganeko zokutofa ezinokuyalelwa ngexesha lesiganeko esisodwa sokutsha. Ngelixa iziganeko zokutofa ezininzi zinokwenzeka ngezi nkqubo zindala, kunzima kakhulu kwaye kuyabiza ukufezekisa.

Kwinkqubo eqhelekileyo yokusabalalisa / i-inline, ukuqala kwesitofu kwenzeka kuxinzelelo olumiselweyo (oluhlala lubizwa ngokuba luxinzelelo lwe-pop) kwaye luphela ngoxinzelelo olumiselweyo. Olu phawu luphumela kwii-injection "ezisisimumu" kwintloko yesilinda evula kwaye ivale kuxinzelelo olugqitywe kukulayishwa kwangaphambili kwasentwasahlobo kufakwe kwiplunger kwi-injector. Nje ukuba uxinzelelo kwi-injector lufikelele kwinqanaba elimiselweyo, i-plunger iphakamisa kwaye inaliti iqala.
