Umbhobho omtsha we-Injector Dlla140p1790 0433172092 ye-Fuel Injector 0445120141

1. Indawo yobushushu be-fuel kwisithuba esiphakathi kweendawo zokudityaniswa kwevalve yenaliti:

Xa ivalufa yenaliti ibuyela, amandla e-kinetic aphulukene ne-shear flow friction phakathi kwesibini sevalve yenaliti kunye ne-gap fuel iguqulwa ibe amandla obushushu, iqondo lobushushu lefilimu ye-oyile ye-gap liyenyuka ngokuthe ngcembe, kwaye ifutha iya kwanda xa ubushushu bunyuka. ukuze kubekho uxinzelelo olongezelelweyo kwifilimu ye-oyile ye-gap Field, umthamo womthwalo wefilimu yeoli uyanda, le nto yimpembelelo ye-thermal wedge. Xa i-shear flow flow ingaqwalaselwa, izinga lokuhamba kwamafutha liyancitshiswa ngenxa yokuchasana kwe-viscous eludongeni. Xa ivalve yenaliti imile okanye ihamba ngesantya esiphantsi, ilahleko yoxinzelelo lwamafutha iguqulwa ibe ngamandla obushushu. Ngexesha elifutshane, ukushisa kunzima ukutshintshela eludongeni oluqinileyo, ngoko ke lula njengenkqubo ye-adiabatic. Ngenxa ye-friction ye-fuel shear flow, ukushisa kwe-fuel kuyanda kwaye kwanda ukwenza intsimi yoxinzelelo olongezelelweyo, eyenza ukuhamba kwe-fuel, okubizwa ngokuba yi-hot wedge flow. Ubunzima befilimu yeoli buchaphazela amandla okuthwala ukunyuka kobushushu befilimu yeoli. Njengoko ubukhulu befilimu yeoli buba buncinci, ubushushu bukhuphuka kwaye umthamo wokuthwala ukhula ngokuthe ngcembe.

2. Impembelelo yeeparamitha zesakhiwo sokudibanisa ivalve yenaliti kwiimpawu zokutywinwa

Kwi-injector, ngenxa yomthamo omncinci wetanki yeoli, ukusebenza kokutywinwa kokudibanisa i-valve yenaliti kuyancitshiswa, okuya kunciphisa kakhulu uxinzelelo kwigumbi loxinzelelo lwe-nozzle. Ngoko ke, i-gap efanelekileyo ibaluleke kakhulu kwiimpawu zokutywinwa kokudibanisa i-valve yenaliti. Ukuqwalasela iteknoloji yokucubungula kunye nokulahleka kokuvuza kweli nqanaba, thatha ngokubanzi i-2 ~ 4μm.
