Diesel Injector Fuel Injector 0445120188 Bosch for Dodge RAM 2500 / RAM 3500 Pickup Truck 6.7L High-Output Cummins

Ukuphuhlisa iModeli yeNkqubo yokuTofwa kweFuel uHlalutyo oluLungelelekileyo lweInjector yeeNjini zeDizili(icandelo 5)

Ngenxa yokuqhekeka, i-jet ye-fuel iguqulwa ibe yi-fuel spray kunye nokusabalalisa ubungakanani obuthile. Ngaphaya koko, i-diameter yokulahla yi-random eqhubekayo yobuninzi, okt inokuthatha naliphi na ixabiso kwisithuba senkcazo yayo. Kule nkalo, i-fuel spray kufuneka ithathelwe ingqalelo kuphela njengento yokuqokelela okanye isethi yamaconsi, kodwa njenge-static aggregate yamaconsi obungakanani obuhlukeneyo.

Ngokwemithetho yokusabalalisa eqwalaselweyo, ubuncinci iiparameters ezimbini ziyafuneka ukuba ufunde i-spectrum yobungakanani be-atomized fuel: umyinge we-drop diameter kunye neempawu zokusabalalisa i-jet (ukusasazwa, uluhlu).

Indlela ye-Sauter mean drop diameter ikhethiwe. Imele umlinganiselo womthamo opheleleyo wawo onke amathontsi kwindawo yawo yonke.

I-atom yamafutha ixhomekeke kwinombolo ye-Weber, eyisixa esingena dimensionless eseka ubudlelwane phakathi kweparamitha ezintathu eziphembelela ukucoleka kwe-atomization yolwelo kwaye ifunyenwe kwintetho.

(2) :DP -I-Pressure drop, i-2 H / m phakathi kwe-nozzle orifice kunye nephakathi apho isitofu senziwa khona i-cd -nozzle orifice diameter, m; s – i-fuel surface tension, N/m Omnye wemithetho esisiseko ye-capillary phenomena ephembelela ukucoleka kwe-atomization ngumthetho weLaplace.

Ikhrayitheriya engenamda idibanisa iiparamitha ezine eziphembelela ukucoleka kwe-atomization yesibaso (3)rT - Uxinaniso lwamafutha kg/m3 phakathi komlomo womlomo kunye neliphakathi ekwenziwa ngalo inaliti; cd - nozzle orifice idayamitha, m; σ - Uxinzelelo lomphezulu wamafutha, i-N/m, i-mT - i-fuel viscosity eguqukayo, i-Ns/m2

Impembelelo ebalulekileyo kwi-atomization ye-fuel ibangelwa isantya apho ulwelo luphuma kwi-orifice yomlomo. Isantya sokuphuma kwesibaso apho uqhekeko luqala khona ngoko nangoko kumngxuma wokuphuma emlonyeni uxhomekeke kwiqela lezinto (4):
