Kugwiritsa ntchito zosefera zapapepala pamainjini agalimoto kukuchulukirachulukira. Komabe, madalaivala ena akadali ndi tsankho pa zosefera zoyambira pamapepala, poganiza kuti kusefa kwa zosefera zapakati papepala sikwabwino. M'malo mwake, fyuluta yapakatikati ya mpweya ili ndi zabwino zambiri poyerekeza ndi fyuluta yamafuta osambira:

1. Kuchita bwino kwa kusefera ndipamwamba kwambiri mpaka 99.5% (mafuta osambira mpweya fyuluta ndi 98%), ndi mlingo kufala fumbi ndi 0.1% -0.3%;

2. Kapangidwe kameneka kamakhala kakang'ono ndipo kakhoza kukhazikitsidwa kumbali iliyonse, osati kokha ndi mapangidwe a magalimoto;

3. Simadya mafuta panthawi yokonza, komanso imatha kusunga ulusi wambiri wa thonje, zomverera ndi zitsulo;

4. Khalidwe laling'ono ndi mtengo wotsika.

Ndikofunikira kugwiritsa ntchito pachimake pamapepala posindikiza fyuluta ya mpweya kuti mpweya wosasefedwa usadutse mu masilinda a injini.

1. Pakuyika, kaya flange, chitoliro cha rabara kapena kugwirizana kwachindunji kumagwiritsidwa ntchito pakati pa fyuluta ya mpweya ndi chitoliro cholowetsa injini, ziyenera kukhala zolimba komanso zodalirika kuti zisawonongeke mpweya. Ma gaskets a mphira ayenera kuikidwa pa malekezero onse a fyuluta; Mtedza wa mapiko a chivundikirocho sayenera kumangika kwambiri kuti musaphwanye chinthu chosefera pamapepala.

2. Panthawi yokonza, chinthu cha fyuluta ya pepala sichiyenera kutsukidwa mu mafuta, apo ayi pepala la fyuluta lidzalephera, ndipo n'zosavuta kuyambitsa ngozi yothamanga. Pokonza, ingogwiritsani ntchito njira yogwedeza, njira yofewa yotsuka (kutsuka pa makwinya) kapena njira yoponderezedwa ya air blowback kuti muchotse fumbi ndi litsiro zomwe zimayikidwa pamwamba pa pepala losefera. Kwa gawo lazosefera, fumbi lomwe likusonkhanitsira fumbi, masamba ndi chitoliro chamkuntho ziyenera kuchotsedwa munthawi yake. Ngakhale itha kusungidwa mosamala nthawi zonse, chinthu chosefera pamapepala sichingabwezeretse magwiridwe ake apachiyambi, ndipo kukana kwake kutulutsa mpweya kumawonjezeka. Choncho, pamene chinthu chosefera pamapepala chiyenera kusamalidwa kachinayi, chiyenera kusinthidwa ndi chinthu chatsopano cha fyuluta. Ngati chinthu chosefera pamapepala chang'ambika, chobowoka, kapena pepala losefera ndi kapu yomaliza zachotsedwa, ziyenera kusinthidwa nthawi yomweyo.

3. Mukamagwiritsa ntchito, m'pofunika kuteteza mwamphamvu kuti fyuluta yapakatikati ikhale yonyowa ndi mvula, chifukwa kamodzi kapepala kamene kamamwa madzi ambiri, kumawonjezera kwambiri kukana kwa mpweya ndikufupikitsa moyo. Komanso, pepala pachimake mpweya fyuluta sayenera kukhudzana ndi mafuta ndi moto.

Injini zamagalimoto zina zimakhala ndi zosefera za cyclone air. Chophimba cha pulasitiki kumapeto kwa gawo la fyuluta ya pepala ndi nsalu. Masamba pachivundikirocho amapangitsa kuti mpweya uzizungulira, ndipo 80% ya fumbi imalekanitsidwa ndi mphamvu ya centrifugal ndikusonkhanitsidwa mu fumbi. Pakati pawo, fumbi lomwe limafika pazosefera zamapepala ndi 20% ya fumbi lokokedwa, ndipo kusefera kwathunthu kuli pafupifupi 99.7%. Chifukwa chake, posamalira fyuluta ya mpweya wa cyclone, samalani kuti musaphonye nsaru ya michere pa sefa.
