Dizilo Injector Fuel Injector 095000-1520 Denso Injector ya Isuzu

Kusintha kwa nanodispersed zosinthika za ufa wa magnetite pakuchita bwino kwa nozzle ya injini ya dizilo (gawo 1)

1. Mawu Oyamba
Vuto la kuwonongeka ndi kung'ambika kwa ma nozzles opopera a injini za dizilo lidakhala lachangu pokhudzana ndi zofunikira zatsopano zoteteza chilengedwe zokhudzana ndi mtundu wamafuta a dizilo. Amakhulupirira kuti izi zikakwaniritsidwa, ndikofunikira, kuti musunge kuchuluka kwamafuta, kuyambitsa zowonjezera zotsutsana ndi kuvala mumafuta. Pachifukwa ichi, muyezo wa ku Europe wamtundu wamafuta a dizilo unayambitsa index ya lubricity [1, 2]. Vutoli lawonekeratu ku Russia, komwe kupanga mafuta okonda zachilengedwe kumakula mwachangu.
Njira yachikhalidwe yowonjezerera mawonekedwe a tribotechnical amafuta, poyambitsa mitundu yosiyanasiyana ya zowonjezera sungunuka mwa iwo, monga momwe zasonyezedwera ndi maphunziro a olemba osiyanasiyana, sizothandiza kwambiri pamafuta. Chifukwa chake, kusungidwa kwamafuta odana ndi kuvala mafuta ndi ntchito yofunika, yankho lomwe limatheka pokhapokha pamaziko a maphunziro ofunikira a njira za tribochemical ndikufufuza zida zatsopano pazifukwa zawo monga zowonjezera.

2. Zida ndi njira
The antiwear wothandizila [3] wopangidwa dizilo mafuta ndi 0.00001% micelles, anapanga pamaziko a mamolekyu olimba pulasitiki lubricant chitsulo okusayidi (Fe3O4), ndi ozungulira mamolekyu a oleic acid (C18H34O2) mu kuchuluka kwa 0.0001%.
Chowonjezeracho chimakhala ndi kukana kumeta ubweya wochepa komanso kuchuluka kwamafuta amafuta a dizilo pamene chowonjezera ichi chikulowetsedwamo. Chowonjezera cha antiwear chinawonjezeredwa ku mafuta a dizilo mu chiŵerengero cha 1/10 pa kutentha kwa 60 ° C ndi kusonkhezera kosalekeza kwa ola limodzi. Mafuta omwe adapezedwa adagwiritsidwa ntchito poyesa mayeso a KI-921M okhala ndi ma jekeseni okhala ndi mphamvu yamaginito [4]. Kuyerekeza mafuta ovala zovala zamafuta, kutengera zomwe zili sulfure, kuyesa kwamafuta omwe ali ndi sulfure 0.035%, 0.2% ndi 0.035% adayambitsidwa ndi zowonjezera zowonjezera pamwambapa. Njira ya mayeso ndi njira yosinthira deta yoyesera pogwiritsa ntchito zida zamakono zamapulogalamu a masamu apakompyuta amaperekedwa mu [5].
