Kafukufuku pa Mphamvu ya Injector Hole Carbon Deposition on Diesel Engine Injection Pressure

Pogwiritsa ntchito injini za dizilo, vuto la ma depositi a kaboni m'mabowo a nozzles a injini zamafuta amapezekanso. Vavu ya singano ikatsekedwa, mafuta otsalira otsala mkati mwa dzenje la jekeseni amapanga filimu yopyapyala yamafuta, yomwe imasweka mosavuta ndi kutentha kwakukulu ndi malo othamanga kwambiri ndipo imapanga ma deposits a carbon. Pambuyo kaboni madipoziti kwaiye, iwo kudziunjikira mkati ndi kutuluka mabowo nozzle, kusintha choyambirira nozzle kamangidwe, zimakhudza yachibadwa otaya mafuta dizilo, kusokoneza akafuna kutsitsi chitukuko, ndi zimakhudza kwambiri kutsitsi ndi kuyaka makhalidwe a injini za dizilo. Kafukufuku kumayiko ena asonyeza kuti pambuyo madipoziti mpweya m'mabowo nozzle wa jekeseni, kuchuluka jekeseni mafuta amachepetsa, kutsitsi khalidwe amachepetsa, kuyaka dzuwa amachepetsa, ndi NO. utsi ukuwonjezeka. Mayeso a Birgel et al. pa benchi ya injini ya silinda imodzi imasonyeza kuti pambuyo pa carbon madipoziti m'mabowo jakisoni, pafupifupi anasonyeza kupanikizika mu yamphamvu akutsikira ndi munthu pazipita 12.2%. Mayeso a Kumagai et al. pa benchi ya injini ya 4-silinda inawonetsa kuti torque ya injini idatsika ndi 9% pambuyo poyika mpweya m'mabowo a jakisoni.
Dongosolo la jakisoni wamafuta ndi chimodzi mwazinthu zofunika kwambiri za injini, ndipo ndi mtima wa injini yonse. Makhalidwe ake jekeseni amakhudza mwachindunji mapangidwe osakaniza mu yamphamvu ndi kuyaka quality7. Mayiko akunja achitapo kanthu potengera kuyika kwa jekeseni wa kaboni pa kupopera ndi kuyaka, koma pali maphunziro ochepa okhudza mphamvu ya jekeseni. Papepalali, kugwiritsa ntchito benchi yoyesera pampu yamafuta, jekeseni watsopano wamafuta ndi jekeseni wamafuta oyika kaboni adagwiritsidwa ntchito poyesa jekeseni wamafuta, komanso mphamvu ya dipoziti ya kaboni mu dzenje la nozzle la jekeseni pamafuta. Kuthamanga kwa jekeseni kwa injini ya dizilo kunayesedwa. ndi chikoka cha makhalidwe kuyaka.
