Abstract.

Labarin ya ba da shawarar zaɓin kimantawa don nazarin ingancin allurar mai ta mai yin injector wanda ke haifar da haɓaka tubalan lissafi a cikin ƙirar injector gama gari tsakanin LMS Imagine.Lab AMESim. Ma'auni na ƙirar injector a cikin labarin sun dace da serial injector Common Rail-type tare da solenoid. Ana nuna yuwuwar wannan hanyar tare da samar da sakamako ta amfani da misalin ƙirar allurar da aka gyara. Bayan sakamakon binciken, an gano fa'idodin tsarin da aka ba da shawarar don tantance ingancin allurar mai.
1. Gabatarwa
Ayyukan allura da atomization na man fetur sun dogara ne akan ƙirar injector: halaye na geometric na jet ɗin mai atomized, tsarin feshin mai, ingantaccen mai atomization, da adadin sauran sigogi na tsarin isar da mai [1, 2]. Don tabbatar da ingantaccen konewar man fetur kuma, saboda haka, samun manyan alamun fasaha da tattalin arziki na injin dizal, ya zama dole don tsara allura mai ma'ana.

Ingancin man atomization yana da alaƙa da fineness da daidaituwa. Dole ne a tsara tsarin tarwatsa jet don samun ingancin feshi a duk matakan allura, gami da matakin farko da na ƙarshe, lokacin da ƙarancin man fetur ya tashi sama da injector. A halin yanzu, ana amfani da ƙirar mai girma uku na sassan isar da mai da tsarin injunan diesel [3]. Koyaya, kalkulaiton mai girma uku aiki ne mai rikitarwa kuma mai cin aiki. Don haka, aikace-aikacen sa a cikin lissafin injectors yana iyakance ga kuma mayar da hankali kan nazarin atomization na man fetur da kuma fesa geometry.

A cikin wasu bincike, ana buƙatar saurin kimanta halayen isar da man fetur, da kuma nazarin yanayin kuzari da halaye masu kyau na atomization na man fetur, alal misali, don tabbatarwa ko kwatanta nau'ikan injectors daban-daban. A cikin warware wasu ayyuka na ƙididdige zaɓukan da aka kwatanta ta ingancinsu na atom ɗin man fetur, zane-zane mai gudana ba koyaushe zai yiwu a yi amfani da su ba.
