I-Diesel Injector Fuel Injector 095000-6140 6261-11-3200 Denso Injector ye-Komatsu

Kusukela emiphumeleni yocwaningo, kungathathwa iziphetho ezintathu ezibalulekile. Ngokukhula kobude obuqinile bodonga lwe-nozzle, amandla e-cavitation ancipha, kuyilapho amandla e-kinetic e-turbulence akhula; umthelela wokuphakama kodonga ku-mass flow rate ekuphumeni kwe-nozzle alibonakali, elikhuphuka kancane ngaphansi kwesimo umfutho omningi womjovo; Ngokukhula kobude obumahhadlahhadla odongeni, isivinini esimaphakathi kanye nesiyaluyalu amandla e-kinetic ehla futhi anda ngokuphawulekayo endaweni ephumayo ngaphansi. isimo somfutho omningi womjovo, ngokulandelana. Kodwa-ke, ngokwanda kokuphakama kodonga olumahhadla, ukuncipha kwe-amplitude yesivinini esisho kanye nokwanda kokuphakama kwamandla e-kinetic enyakazayo endaweni yokuphuma emlonyeni kokubili kuncane kakhulu ngaphansi kwesimo somfutho ophansi womjovo; isiphithiphithi samandla e-kinetic endaweni ye-cavity eduze nendawo ephakeme ye-orifice inkulu kunaleyo eseduze nendawo engezansi nendawo emaphakathi. Isizukulwane kanye nokuwa kwe-cavitation kungathuthukisa amandla e-kinetic we-turbulence at the orifice exit.

Ukugeleza kukaphethiloli ngesivinini esiphezulu ku-nozzle yomjovo kaphethiloli wenjini esebenza ngodizili wesitimela enengcindezi ephezulu kwenza kube lula kakhulu ngaphakathi. I-phenomenon ye-cavitation iyakhiwa. Inani elikhulu locwaningo libonise ukuthi umphumela we-cavitation nezici ze-turbulence ngaphakathi kwe-nozzle zinomthelela omkhulu ku-atomization ye-jet kaphethiloli kanye nokusebenza kwamandla nokukhipha kwenjini ye-diesel. Kungabonakala ukuthi ukuthuthukiswa komfutho womjovo ophezulu kanye nomjovo we-microporous ohlelweni lwesimanje lomjovo kawoyela wesitimela ocindezela kakhulu ubaluleke kakhulu ocwaningweni lwe-cavitation phenomenon ngaphakathi kwe-nozzle.
