I-Diesel Injector Fuel Injector 095000-5670 23670-30090 23670-39125 Denso Injector for Toyota

Ubuchwepheshe bomjovo we-in-cylinder buhluke kakhulu kubuchwepheshe bomjovo we-port. Ezinjini zikaphethiloli ezijova ngqo, kungakhathaliseki ukuthi zamukela ukuvutha okuqinile ngaphansi kwezimo zomthwalo ophansi, zamukela ukuvutha kwestratified ngaphansi kwezimo zomthwalo ophakathi, noma zamukela uhlobo oluvuthayo lwengxube yesilinganiso sokulingana ngaphansi kwezimo zomthwalo ophezulu, umjovo kaphethiloli womjovo oqondile Ikhwalithi of the atomization idlala indima ebalulekile ekwakhekeni ingxube in isilinda.
Ngokwemodi yokushayela, ama-injection ezinjini zikaphethiloli womjovo oqondile angahlukaniswa ngama-injection kagesi kanye nama-piezoelectric crystal injectors. Umjovo kaphethiloli we-electromagnetic ulawula ikakhulukazi ukuvuleka nokuhlala kwe-valve yenaliti ngokunika amandla ikhoyili, kanti isijojo sikaphethiloli sekristalu ye-piezoelectric ikakhulukazi sisebenzisa umphumela we-piezoelectric ophambene ukulawula ukuphakanyiswa kwenaliti ye-shaft, ukuze ibone ukuvuleka nokuvalwa i-fuel injector. . Izinzuzo eziyinhloko zama-piezoelectric crystal direct injection kaphethiloli ama-injection isikhathi esifushane kakhulu sokuphendula umjovo kaphethiloli, ukulinganisa uphethiloli okunembile kanye nokuphindaphinda okuhle. I-Siemens injector ingafinyelela ukuphakama okuphezulu kwe-pintle ngaphakathi kwe-20us, futhi isikhathi sokuvala singama-200us. Ukuphakanyiswa kwe-pintle kungalawulwa ngokulawula i-voltage yokulayisha yekristalu ye-piezoelectric, ukuze umthamo womjovo kaphethiloli ulungiswe kahle ngaphansi kwesimo sokucindezela okuphezulu kakhulu komjovo.
Ama-injection kaphethiloli womjovo oqondile angahlukaniswa ngohlobo lwe-swirl, uhlobo lwezimbobo eziningi kanye nohlobo lokuvula lwangaphandle ngokusho komumo wesifutho. Kuma-injection ohlobo lwe-swirl, lapho uphethiloli wengcindezi ephezulu ugeleza kujeneretha ye-vortex ngaphakathi komjovo, kwakheka ikhoni engenalutho yesifutho endaweni yokuphuma komjovo. Uphethiloli ofuthwe ungaphansi kwesenzo samandla e-centrifugal futhi ushayisana nomoya ozungezile, ngakho ikhwalithi ye-atomization kaphethiloli iba ngcono. Kodwa-ke, isakhiwo esiyikhoyili esingenalutho esakhiwe lapho kuphuma khona umlomo wombhobho sithikamezwa kakhulu ukucindezela komjovo kanye nokucindezela okungemuva okuzungezile, ikakhulukazi uma umfutho wangemuva uphezulu. Ngakho-ke, lapho uwoyela ujovwa ngesikhathi sokushaywa, ngenxa yokucindezela okuncane kwemvelo okungemuva, isakhiwo sesifutho esakhiwe sibonisa ukwakheka kwe-conical okungenalutho futhi okuhlakazekayo, okuhambisana nenqubo yokuxuba igesi kawoyela. Ikhwalithi engcono ye-atomization ifinyelelwa ngisho nasezingcindezini eziphansi zokujova. Kodwa-ke, lapho amafutha ejojowe ngesikhathi sokucindezela, ngenxa yokucindezela okuphezulu kwe-ambient back, isakhiwo se-spray siyancipha, esingahambisani nokwakheka kwegesi exutshwe kusilinda.
