Munyika, chinangwa chikuru ndechekuvandudza hupfumi hwemafuta pasina zvibayiro zvine chekuita nehumwe maitiro ekuita. Mune nhanho yekutanga, yevaned diffuser parameter yekudzidza inoratidza kuti kuvandudzwa kwehunyanzvi munzvimbo dzakakodzera dzekushanda kunogoneka pamutengo wekuderedzwa kwemepu. Kupedzisa kubva pane mhedzisiro matatu akasiyana geometries ane akasiyana kuoma kwakavakirwa pane vaned diffusers akagadzirwa. Mhedzisiro kubva kune inopisa gasi bvunzo yekumira uye injini yekuyedza rig inoratidza kuti masisitimu ese anokwanisa kuwedzera compressor kunyatsoshanda uye nekudaro kuvandudza hupfumi hwemafuta mumhando huru yekutyaira yeinjini dzinorema.
Mamwe matambudziko anomiririrwa nekudiwa kwekusimba kwakanyanya, kuderera kweruzha kuburitsa uye kuita kwakanaka kweinjini. Naizvozvo, dhizaini yecompressor system inogara iri kukanganisa pakati pekushanda kwepamusoro, hupamhi hwemepu yakafara, huremu hwakaderera hweiyo impeller uye kusimba kwepamusoro kunotungamira kumatanho ecompressor nekurasikirwa kukuru kweaerodynamic mumhando huru yekutyaira yemotokari refu uye nekudaro a kuderera kwehupfumi hwemafuta. Kugadzirisa dambudziko iri rakakosha rekugadzira compressor nekuunza inoshanduka geometry inogona kutungamira mukuderedzwa kwemitengo yevaridzi inova ndiyo yekutanga nzvimbo yekutengesa maererano neanorema basa injini. Kunze kwemavharuvhu ekudzokorodza akaiswa mumotokari yevatyairi turbocharger, macompressor ane akasiyana geometry haana kuwana nzira yekugadzira akateedzana kunyangwe tsvakiridzo yakadzama yakaitwa pandima iyi.
Matatu akasiyana compressor akagadzirwa aine chinangwa chekuvandudza hupfumi hwemafuta einjini dzinorema-munzvimbo huru yekutyaira pasina kukanganiswa maererano neakayerwa simba, peak torque, kusimba kwekuwedzera uye kusimba. Mune nhanho yekutanga, zvinodikanwa zveinjini zvine chekuita neiyo compressor nhanho zvakatorwa uye inonyanya kukosha compressor inoshanda nzvimbo dzinozivikanwa. Iyo huru yekutyaira marori akareba-akareba anofanana nenzvimbo dzekushanda pane yakakwira pressure ratios uye yakaderera misa inoyerera. Kurasikirwa kweAerodynamic nekuda kweiyo tangential kuyerera angles mune vaneless diffuser inoita basa guru mune iyi inoshanda renji.
