Fuel Injector 107-1230 1071230 for Caterpillar 950f 950f II 960f Caterpillar 3114 Injini Caterpillar 3116 Injini

Isiphumo sobubanzi bombhobho, uxinzelelo lwenaliti kunye neqondo lobushushu le-ambient kwiimpawu zokutshiza kwi-injini ye-diesel(Icandelo 4)

Njengoko igrafu ibonisa ubude bokungena kuMfanekiso 9 kunye noMfanekiso we-10 usebenzisa i-ambient eyahlukileyo.

iqondo lobushushu le-0.12 mm kunye ne-0.2 mm lombhobho wedayamitha lihlala linyuka kunye nexesha elithathiweyo kwaye zombini kwiqondo lobushushu ubude bokungena abuniki ngokwahlukileyo kakhulu. Oku kungenxa yoluhlu phakathi kwamaqondo obushushu angekho mkhulu kakhulu. Nangona kunjalo, uxinzelelo lwenaliti luphembelela ubude bokungena kwesitshizi, apho uxinzelelo lwenaliti eyahlukileyo eyi-40 MPa, 70 MPa kunye ne-140 MPa kunye noxinzelelo lwe-ambient 1 MPa kuxinzelelo lomoya. Njengesitofu soxinzelelo oluphezulu, ukungena kobude obude kuya kuba nefuthe. Oku kungenxa yokuba isitshizi sasixhathise ngoxinzelelo lwe-ambient.

Umzobo we-11 kunye ne-12 ubonisa iigrafu zobude bokuhlukana kunye no-0.12 mm kunye no-0.2 mm ububanzi bombhobho. Kukho iziphumo eziguquguqukayo kwiqondo lobushushu elingama-500 K, apho uxinzelelo lwenaliti yi-140 MPa kunye nedayamitha yomlomo oyi-0.2 mm yonyuka ngokumangalisayo ukusuka kwi-1 mm ukuya kwi-2.3 mm. Oku mhlawumbi kungenxa yokuba i-droplet ayizange ihlukane kwaye ithatha ixesha elide, oku kubizwa njengecandelo le-ligament. Thelekisa ubushushu be-700 K kwi-MPa ye-140 kunye ne-0.2 mm ubude bokuphuka buhamba ngokuzinzileyo kunye nexesha. Ngaloo ndlela iqondo lobushushu liphembelela kubushushu obuphezulu be-ambient obusetyenzisiweyo, ubude obufutshane bokwahlukana kwenzeka kwicandelo elingundoqo.

4. Isiphelo

Olu phononongo lubonise ukuhamba kokulinganisa kwamafutha aqukuqelayo kumbhobho wokutshiza phambi kokutsha. Uxinzelelo lwenaliti ephantsi kwigumbi luyakuphazamisa ukophuka kwesitshizi sesibaso ukuya kumathontsi acoleke kakhulu phambi kokuba kuqale ukutshiswa kwamafutha. Ukutshintsha kweqondo lobushushu kwigumbi nako kuchaphazela ubude bokungena kokutshiza. Kubushushu obuphezulu be-ambient, i-fuel iba ngumphunga ngokulula kwaye ibasa isibaso ngokwaso. Kwakhona, ububanzi bombhobho bukwachaphazela ubude bokwaphuka kombhobho wokutshiza njengoko kuphenjelelwa luxinzelelo oluphezulu lwenaliti apho ubude bokwahlukana buba bufutshane.
