Isitofu se-Diesel 320-0677 Injector ye-Fuel 2645A746 Injector Iyahambelana neCaterpillar Cat C6.6 Injini ye-320dl Excavator

I-Cavitation Ngaphakathi koxinzelelo oluphezulu lweMibhobho yesitofu seFuel eNgaphandle(ICANDELO 1)

Intshayelelo Uxinzelelo olunyusiweyo lwesitofu kunye neendawo zokuhombisa zombhobho ezincinci zisetyenziswa kwiinkqubo zokutofa kwiinjini zanamhlanje zokutofa ngokuthe ngqo ukomeleza iatomization kunye nokuhambisa ubunzima bamafutha obaneleyo ngokukhawuleza.Ukuhamba ngaphakathi kwe-injector kufuneka kuguquke ngokukhawuleza ukungena kwi-nozzle orifice, apho kwiimeko ezininzi kubangela ukuba i-cavitation ibonakale kwicala elisezantsi le-orifice inlet.I-Cavitation ngokuqhelekileyo ithathwa njengengozi, kuba ukudilika kwee-bubbles ze-cavitation kungonakalisa iindawo ezihlala zihlala njengentsimbi eqinile.Ukongeza, ngelixa ezinye iindlela ze-cavitation zibonakaliswe ukuba zinenzuzo kwi-atomization, nokususa idiphozithi yekhabhoni kwi-injection yepetroli, i-hydraulic flip icinezela i-atomization ngokupheleleyo[1].Kuze kube yilapho i-cavitation iqondwa ngcono kwaye kulula ukuyilawula, kubonakala kunengqiqo ukuyila i-nozzle ye-injector ngendlela yokukhusela i-cavitation.Eyona ndlela isebenzayo yokufunda i-nozzle orifice flow cavitation kukwakha i-injector nge-optically accessible nozzle ukuze i-orifice flow ibonakale ngokuthe ngqo.Lo asingomsebenzi olula.Izinto zobunjineli ezibonakala elubala zidla ngokuba brittle kubushushu begumbi.Ngelixa izixhobo ezibhityileyo zihlala zinemodyuli ephezulu yeelastiki kunye namandla anamandla enkcazo-bungcali, iziphene ezishiywe kulungiso olufunekayo ukwenza ijometri efunekayo zinokuwunciphisa kakhulu umthamo womthwalo wecandelo eligqityiweyo.Umba obalulekileyo ngeengcebiso ze-optical kukufumana umdlalo phakathi kwee-indices of refraction for the nozzle material kunye nolwelo olusetyenzisiweyo.Ukuba azihambelani, ke imiphetho yesicatshulwa iya kubonakala imnyama kwi-shadowgram.Oko kuya kwenza kube nzima ukwenza umfanekiso we-cavitation eludongeni.

I-Acrylic kunye ne-quartz inesalathiso esisondela kuninzi lwamafutha (kunye namanzi) kodwa ngelishwa banamandla aphantsi obunzima ngenxa yokungahambi kakuhle.Ngokuqhelekileyo zophuka kakuhle ngaphantsi koxinzelelo lwamafutha oluyinyani.ISapphire, kwelinye icala, ineempawu ezishushu kunye namandla afana nentsimbi, kodwa isalathiso esingalunganga sihambelana nolwelo olunomdla.
