Diesel Injector Roj Injector 095000-1520 Denso Injector rau Isuzu

Kev cuam tshuam ntawm kev hloov pauv ntawm nanodispersed ntawm magnetite hmoov ntawm tshuaj tsuag nozzle efficiency ntawm diesel cav injector (Part 1)

1. Taw qhia
Qhov teeb meem ntawm kev hnav thiab tsim kua muag ntawm cov tshuaj tsuag nozzles ntawm lub tshuab hluav taws xob tau dhau los ua kev kub ntxhov hauv kev sib txuas nrog cov kev cai tshiab rau kev tiv thaiv ib puag ncig ntsig txog qhov zoo ntawm cov roj diesel. Nws ntseeg tau tias thaum cov kev cai no tau ua tiav, nws yog qhov tsim nyog, txhawm rau tswj cov qib lubrication, ua kom paub cov khoom siv los tiv thaiv kev hnav rau hauv cov roj. Nyob rau hauv no hais txog, tus qauv European rau qhov zoo ntawm cov roj diesel qhia qhov ntsuas ntawm lubricity [1, 2]. Qhov teeb meem no tau pom meej meej nyob rau hauv Russia, qhov chaw tsim khoom ntawm ib puag ncig tus phooj ywg roj loj hlob sai heev.
Txoj hauv kev ib txwm ua kom muaj cov yam ntxwv tribotechnical ntawm lubricants, los ntawm kev qhia ntau hom soluble additives hauv lawv, raws li qhia los ntawm cov kev tshawb fawb ntawm cov kws sau ntawv sib txawv, tsis zoo rau cov roj. Yog li ntawd, kev khaws cia ntawm cov khoom siv los tiv thaiv cov roj yog ib txoj haujlwm tseem ceeb, cov kev daws teeb meem tsuas yog ua tau raws li cov kev tshawb fawb tseem ceeb ntawm cov txheej txheem tribochemical thiab tshawb nrhiav cov ntaub ntawv tshiab ntawm lawv lub hauv paus raws li cov khoom ntxiv.

2. Cov ntaub ntawv thiab cov txheej txheem
Tus neeg sawv cev antiwear [3] muaj cov roj diesel nrog 0.00001% micelles, tsim los ntawm cov molecules ntawm cov khoom yas lubricant ntawm hlau oxide (Fe3O4), thiab nrog ib puag ncig molecules ntawm oleic acid (C18H34O2) nyob rau hauv tus nqi ntawm 0.0001%.
Cov additive muaj tsawg shear kuj thiab nce lubricity ntawm diesel roj thaum no additive yog nkag rau hauv nws. Cov tshuaj tiv thaiv kab mob tau ntxiv rau cov roj diesel hauv qhov sib piv ntawm 1/10 ntawm qhov kub ntawm 60 ° C thiab txuas ntxiv mus rau ib teev. Cov roj tau txais tau siv rau kev khiav hauj lwm hauv qhov ntsuas qhov ntsuas KI-921M nruab nrog cov tshuaj txhaj nrog lub hauv paus sib nqus [4]. Txhawm rau sib piv cov khoom tiv thaiv ntawm cov roj, nyob ntawm seb cov ntsiab lus ntawm leej faj, kev sim tau ua rau cov roj nrog cov ntsiab lus ntawm cov leej faj ntawm 0.035%, 0.2% thiab 0.035% nrog rau cov tshuaj tiv thaiv saum toj no tau qhia. Cov chav kawm ntawm kev xeem thiab cov txheej txheem rau kev ua cov ntaub ntawv sim siv cov cuab yeej ntawm cov khoom siv software niaj hnub ntawm computer lej tau muab rau hauv [5].
