I-Diesel Injector Fuel Injector 0445110502 Bosch for Uaz Hunter/Patriot 2.0CD 08

Uhlalutyo lwamazwe adlulayo kwii-injini ze-CI kunye nokusetyenziswa kweendlela zokukhanya

Abstract.

Eyona njongo yophando yayikukuchaza ukulibaziseka kwexesha lokwenyani lokutofa ngokuchasene nexesha le
isiginali yokulawula umbane yepiezoelectric kunye ne-electromagnetic fuel injectors.Umzuzwana
Injongo yalo msebenzi ibiluvandlakanyo lwefuthe leeparamitha zesitofu esiqhelekileyo koku
ukulibazisa.Uhlalutyo lwalugxininise ekuveleni kweempawu zokulawula ezifanelekileyo ezirekhodiweyo
ukusetyenziswa kwenkqubo yokufumana idatha eguqukayo ngokukhawuleza kwaye kuthelekiswa nedatha erekhodwe ngokuphezulu
ikhamera yesantya.Iimvavanyo zenziwa kwigumbi levolyum rhoqo kwiintlobo ezahlukeneyo zesitofu
esetyenziswa kwiinjini zokutsha ezinenaliti ngqo yamafutha edizili.Iimvavanyo zenziwa phantsi
iimeko eziguquguqukayo: uxinzelelo lwamafutha olwahlukileyo, uxinzelelo lomoya obuyayo kunye nexesha lexesha lokutofa.
1. Intshayelelo
Inaliti yoxinzelelo oluphezulu lwamafutha angamalwelo aphunyezwa yinkqubo kaloliwe eqhelekileyo ifuna ukuchaneka okuphezulu kwisibaso
ubungakanani obuziswe kwigumbi lokutsha nge-injector.Ngoku kukho iindidi ezimbini eziphambili zee-injection
eqhele ukusetyenziswa kuzo zombini i-ignition yoxinzelelo kunye ne-spark ignition injini: i-electromagnetic kunye
piezoelectric.Nangona uxinzelelo lwamafutha okusebenza kwiinkqubo zokutofa kwepetroli lusezantsi kakhulu
uthelekiso kwiinkqubo zamafutha edizili, kodwa amaxesha okuvula isitofu aphantse afane kuzo zombini iindidi
ukwakhiwa.Loo nto yenza ukuba iimfuno zifane kwi-CI kunye ne-SI ii-injection.Ezi zixhobo kufuneka zibe
ephawulwa ngokuphendula okunokwenzeka ngokukhawuleza kwiimpawu zolawulo ezifanelekileyo zombini ukuvulwa nokuvala ukusebenza.
Payri et al.[1] iphande ifuthe letekhnoloji ye-electromagnetic kunye ne-piezoelectric kwi
inkqubo yokutofa ye-piezoelectric esebenza ngokungathanga ngqo kunye ne-solenoid injectors.Kuloo nkalo hydraulic
iimpawu zalungiselelwa zombini uyilo kwaye emva koko zithelekiswa enye kwenye.Kolu phando
Kwasetyenziswa isalathisi sexabiso lepetroli esekwe kwindlela yeBosch.Iziphumo eziphunyeziweyo zibonise ukusebenza ngokukhawuleza kwe
i-piezo-injection ithelekisa i-solenoid.Oko kuthetha ukuba ukulibaziseka kwabo kwe-hydraulic kuncinci.I
iiyantlukwano zazikhula ngokungafaniyo noxinzelelo lwenaliti.Uqwalaselo lwesibini ukusuka
olo vavanyo yayiyisantya esiphezulu sokuhamba kwamafutha e-piezo-injector xa kuthelekiswa nolunye uyilo olufanayo
umngxuma ububanzi.
Uphando olufanayo lwenziwa nguYu et al.[2], kodwa kuloo meko amafutha akhethiweyo kuphando aye
i-kerosene kunye ne-diesel fuel.Ngokusekelwe kuphela kwiimpawu zokulawula kunye nokwahluka kwesantya sokuhamba kwamafutha ukusuka kwi-injector
umlomo wombhobho, ukulibaziseka kwesitofu ngokuchasene nexesha lokuvula umbane kwafunyanwa.Amaxabiso oku
iparameter yayisoloko izimele ngokuzimeleyo yoxinzelelo lwenaliti (kule meko 60 kunye ne-100 MPa) kunye nokulibaziseka
amaxesha ngokulandelelanayo ayeyi-0.45 ms ye-piezo- kunye ne-0.55 ms ye-solenoid injector.Ukongeza, ukuhamba ngokukhawuleza
ukusuka kumbhobho wesitofu ukwenzela uxinzelelo olusezantsi lwenaliti lwabonwa.Loo nyaniso inika iingenelo ezibalulekileyo
ukusebenza kwe-injini yokutsha efana ne-atomization engcono kunye nokuphuma kwepetroli.Ababhali abaxeliweyo basebenzise
