Asi mamiriro ezvinhu aripo (kuchena kwemafuta matsva hakuna kukwana, kusvibiswa kwemidziyo yekufambisa mafuta, kuchena kwetangi yemafuta kwakashata, kuparara uye kuparara kwepombi yemafuta), kunatsiridza kurongeka kwemafuta kunoderedza Sevhisi yehupenyu hwesefa chinhu, asi dzikisa kurongeka kwesefa uye kukanganisa zvakanyanya basa repombi jekiseni remafuta uye jekiseni remafuta.Pasi pechiyero, zvinodikanwa kuve nechokwadi chekuisa mafuta akachena kune locomotive (inopinza nepamusoro-soro sefa firita pre-filtration), tangi yemafuta uye locomotive mafuta pombi system yakachena zvakakwana, panguva imwe chete, iko kurongeka kwesefa kwemafuta sefa. uye coarse sefa yakagadziriswa mune yakakwira chaiyo.Zvinokurudzirwa kuti kurongeka kwemafuta asina kuchena sefa inofanira kuva 20μm, iyo isiri-yemagetsi jekiseni mafuta yakanaka sefa inofanira kuva 10μm, uye iyo yemagetsi jekiseni mafuta yakanaka sefa inofanira kuva 5μm.Mafuta asati apinzwa mutangi hombe yelocomotive, mafuta anonatswa nesefa ine filtration accuracy ye 5μm, zvichida nemudziyo wekubvisa mvura.

Yakasiyana injini nekuda kwekutsva kwekamuri chimiro, hupfumi hwakakwana uye kuita kwesimba, inofanirwa kuve neyakasiyana jekiseni pressure.Zvakadai se4125 sere injini yemafuta e125 + 5 kg/cm "‚ 490 injini iri 175 kg/cm".Chimwe chimiro cheinjini yemafuta jekiseni kupfapfaidza kudzvanywa kwemafuta kunotemerwa nekuyedza , yakakwira zvakanyanya kana yakaderera njodzi yakakura.Kukuvara kwekumanikidza kwakaderera jekiseni ‚ (1) kuderera kwejekiseni kudzvanywa ‚ kwete chete kwakashata ‚ mafuta atomu uye kuderedza ‚ siyana kunoita kuti isakwanise mukamuri yese;Impact ine compressed air mix ‚ inotungamira mukupisa kusinga peri, exhaust utsi uye kabhoni deposition.(2) nekuda kweiyo jekiseni dzvinyiriro chitubu kudzikisira ‚ kufanopfapfaidza mafuta nozzle valve valve mumuviri wetsono wakanamira panzvimbo yakavhurika.
