Kubva pakuona kwemaitiro ekugara ane simba, mushure mekutsvaga, iyo dynamic motion equation yetsono yekusimudza valve yakagadzirwa, uye ichienzaniswa neiyo static balance equation. Kuburikidza nenhevedzano yetsvakiridzo yekuyedza uye ongororo yetioretical, mhedziso dzakatorwa ndedzinotevera:, zvichienzaniswa neiyo static state, iyo ine simba yekuvhura yekumanikidza yevharuvhu yetsono yakakwira zvakanyanya, asi simba rekuvhara rekuvhara rakaderera, iro rine hukama ne mamiriro ekushanda kweinjini. Nekuti vharafu yetsono ine hunhu hwekugara kwesimba, inowedzera dhayamita yekudhonza kwemafuta muchikamu chekupedzisira chejekiseni, nekudaro ichidzikisa kunaka kwekupfapfaidza, uye kunyange kupfupisa hupenyu hwehupfu hwemafuta, zvichiunza kutyisidzira kune emission index. . Mukuita kwekushandisa kubatanidza vheji yetsono yejekiseni, nekuda kwenzvimbo ine hutsinye hwekushanda, iyo yekuisa chisimbiso chekoni chinowanzo pfeka uye kubvaruka. Chikonzero chacho chinokonzerwa nekusachena kunogadzirwa mumafuta uye simba rinokonzera rinokonzerwa kana valve yetsono yakagara. Mushure mekupfeka uye kubvaruka, zvinokonzeresa deformation yekuisa chisimbiso koni, kuwedzera kushata kwepamusoro, kudzikisa zvakanyanya kuisa chisimbiso, uye kutadza kuburitsa yakanaka yekupfapfaidza maitiro. Zvakare, kudonha kwemafuta kuchaitika, uye mafuta edhiziri haagone kupiswa zvizere. Mukamuri yekupisa, maburi ejekiseni uye nhengo dzinotonhora dzinoshanda, madhipoziti ekabhoni akawandisa anogadzirwa, zvichikonzera kuvharika kwemaburi ejekiseni. Pakupedzisira, simba reinjini yedhiziri rakaderedzwa zvakanyanya, zvichiita kuti mafuta awedzere kushandiswa.
