Yenyani eNtsha yeKati eNtsha yePerkins i-Diesel Fuel Injector 2645A743 321-0990 10r-7668 Iyahambelana ne-Perkins Pj Injini

Isiphumo sobubanzi bombhobho, uxinzelelo lwenaliti kunye neqondo lobushushu le-ambient kwiimpawu zokutshiza kwi-injini ye-diesel(Icandelo 3)

3. Iziphumo kunye nengxoxo

Olu hlalutyo lusebenzise i-diameters ezimbini ezahlukeneyo eziyi-0.20 mm kunye ne-0.12 mm. Olu linganiso kusetyenziswa amaqondo obushushu ahlukeneyo ahlukeneyo kwi-500 K kunye ne-700 K kuxinzelelo ngalunye lwenaliti linganisa ne-40 MPa, 70 MPa kunye ne-140 MPa. Injongo yolu kulinganisa kukuphanda uhlobo olwahlukileyo lweempawu zokutshiza eziphenjelelwa yidayamitha yombhobho, ubushushu obuthile kunye noxinzelelo lwenaliti yenjini yedizili. Uhlalutyo lweempawu zokutshiza zolu mlinganiso lugxininise ngakumbi kwidayamitha yedropha, ubude bokungena kunye nobude bokuqhekeka obunefuthe kusetyenziso lweparamitha. Uvakalelo lwegridi luvavanyiwe kwimodeli enobungakanani begridi obahlukeneyo. Ubungakanani begridi bohlulwe baba ngamanqanaba amathathu arhabaxa, aphakathi kunye neegridi ezicolekileyo. Itheyibhile 2 ibonisa inani leezakhi kunye neendawo zokuhlala kwiqela ngalinye legridi yobukhulu obahlukeneyo.

Ngaphandle koko, inani lezinto lisuka kwi-24997 ukuya kwi-114555 element. Inani lee-elementi ngokucacileyo lilungelelaniswa ngokuthe ngqo kumanani eendawo ngokunyuka kwinqanaba leegridi zobukhulu ukusuka koburhabaxa ukuya kwehle kunye nenqanaba lokugudisa ukusuka phantsi ukuya phezulu.

Umzobo wesi-6 ubonisa ukuba kwi-40 MPa idayamitha yethontsi kwi-0.20 mm kunye ne-500 K ipharamitha ibonisa ubukhulu obungakumbi bombala obomvu bumele ithontsi lobungakanani obukhulu xa kuthelekiswa ne-0.12 mm 700 K. kunye ne-0.2 mm ziboniswe kuMfanekiso 7 no-8. Njengoko kubonisiwe kwiigrafu, zibonisa ukuba ipateni ubungakanani bokusabalalisa i-droplet ihambelana enye kwenye. Ukuphakama kobushushu be-ambient kunye noxinzelelo lwenaliti kunika i-droplet diameter encinci.

Isiphumo sichaza ukuba i-fuel encinci efakwe kwigumbi inokubangela ukutsha okuphantsi. Kwangaxeshanye idayamitha yethontsi ixhomekeke kutsalo lwe-aerodynamic kwigumbi inokuchaphazela i-droplet diameter eyenziwe encinci xa umoya ungqubana namafutha.
