I-Diesel Injector Fuel Injector 095000-1520 Denso Injector ye-Isuzu

Umthelela wokuguqulwa kwe-nanodispersed yama-magnetite powders ekusebenzeni kahle kwenozzle ye-nozzle ye-injector yenjini ye-diesel (ingxenye 1)

1. Isingeniso
Inkinga yokuguga nokudabuka kwemibhobho yezifutho zezinjini zikadizili yaphuthuma maqondana nezidingo ezintsha zokuvikelwa kwemvelo eziphathelene nekhwalithi kaphethiloli kadizili. Kukholelwa ukuthi lapho lezi zidingo zihlangene, kuyadingeka, ukuze kugcinwe izinga lokuthambisa, ukwethula izithasiselo zokulwa nokugqoka kuphethiloli. Kulokhu, indinganiso yaseYurophu yekhwalithi kaphethiloli wedizili yethula inkomba ye-lubricity [1, 2]. Le nkinga iye yabonakala ngokucacile eRussia, lapho ukukhiqizwa kukaphethiloli ohambisana nemvelo kukhula ngokushesha okukhulu.
Indlela yendabuko yokwandisa izici ze-tribotechnical zamafutha, ngokwethula izinhlobo ezihlukahlukene zezithasiselo ezincibilikayo kuzo, njengoba kuboniswa izifundo zababhali abahlukene, ayisebenzi kakhulu kumafutha. Ngakho-ke, ukulondolozwa kwezakhiwo zokulwa nokugqoka kukaphethiloli kuwumsebenzi obalulekile, isisombululo sawo esingenzeka kuphela ngesisekelo socwaningo oluyisisekelo lwezinqubo ze-tribochemical kanye nokusesha izinto ezintsha ngesisekelo sazo njengezithasiselo.

2. Izinto kanye nezindlela
I-agent ye-antiwear [3] ehlanganisa uphethiloli we-diesel nama-micelles angu-0.00001%, eyakhiwe ngesisekelo sama-molecule e-plastic lubricant eqinile ye-iron oxide (Fe3O4), kanye nama-molecule azungezile e-oleic acid (C18H34O2) enani lika-0.0001%.
I-additive inokumelana okuphansi kwe-shear kanye nokunyuka kokuthambisa kukaphethiloli we-diesel uma lesi sithasiselo singeniswa kuso. Isengezo se-antiwear sengezwe kuphethiloli we-diesel ngesilinganiso se-1/10 ekushiseni kwama-60 ° C nokugqugquzela okuqhubekayo ihora elilodwa. Uphethiloli otholiwe usetshenziselwe ukusebenza endaweni yokuhlola i-KI-921M efakwe ama-injection anensimu kazibuthe yangaphakathi [4]. Ukuqhathanisa izakhiwo ze-antiwear zamafutha, ngokuya ngokuqukethwe kwesibabule, kwenziwa ukuhlolwa kwamafutha anokuqukethwe kwesibabule okungu-0.035%, 0.2% no-0.035% ngesengezo se-antiwear esingenhla esethulwe. Isifundo sokuhlolwa kanye nenqubo yokucubungula idatha yokuhlola kusetshenziswa amathuluzi emikhiqizo yesofthiwe yesimanje yezibalo zekhompyutha kunikezwa kokuthi [5].
