Emhlabeni, inhloso enkulu ukuthuthukisa ukonga kukaphethiloli ngaphandle kokuzinikela maqondana nanoma iyiphi enye indlela yokusebenza.Esinyathelweni sokuqala, ucwaningo lwepharamitha ye-diffuser ene-vaned lubonisa ukuthi ukuthuthukiswa kokusebenza kahle ezindaweni ezifanele zokusebenza kungenzeka ngezindleko zobubanzi obuncishisiwe bemephu.Ukuphetha ngemiphumela amajiyometri amathathu aguquguqukayo anobunzima obuhlukahlukene ngokusekelwe kuma-vaned diffuser adizayinelwe.Imiphumela evela endaweni yokuhlola igesi eshisayo kanye nemishini yokuhlola injini ibonisa ukuthi wonke amasistimu ayakwazi ukukhulisa ukusebenza kahle kwe-compressor futhi ngaleyo ndlela athuthukise ukonga kukaphethiloli kuhlu lokushayela oluyinhloko lezinjini ezisebenza kanzima.
Izinselele ezengeziwe zimelelwa isidingo sokuqina okuphezulu, ukukhishwa komsindo omncane nokusebenza okuhle kwesikhashana kwenjini.Ngakho-ke, ukuklanywa kohlelo lwe-compressor kuhlale kuwukuyekethisa phakathi kokusebenza kahle okuphezulu, ububanzi bemephu ebanzi, isisindo esiphansi se-impeller kanye nokuqina okuphezulu okuholela ezigabeni ze-compressor ezinokulahlekelwa okuphawulekayo kwe-aerodynamic ebangeni eliyinhloko lokushayela lezimoto ezihamba isikhathi eside futhi ngaleyo ndlela ukwehla ukonga kukaphethiloli.Ukuxazulula le nkinga eyisisekelo yokuklama i-compressor ngokwethula i-geometry eguquguqukayo kungaholela ekwehlisweni kwezindleko eziphelele zobunikazi okuyindawo yokuthengisa ehamba phambili mayelana nezinjini ezisindayo.Ngaphandle kwama-valve aphinde asetshenziswe kuma-turbocharger emoto yabagibeli, ama-compressor ane-geometry eguquguqukayo awakayitholi indlela yawo ekukhiqizeni uchungechunge nakuba ucwaningo olunzulu selwenziwe kulo mkhakha.
Kuye kwathuthukiswa ama-compressor amathathu aguquguqukayo ngenhloso yokuthuthukisa ukonga kukaphethiloli ezinjinini ezisebenza kanzima ebangeni eliyinhloko lokushayela ngaphandle kokuwohloka mayelana namandla alinganiselwe, i-torque ephezulu, ukuqina kokuqina nokuqina.Esinyathelweni sokuqala, izidingo zenjini maqondana nesiteji se-compressor ziye zatholwa futhi izindawo zokusebenza ze-compressor ezifanele kakhulu zikhonjiwe.Ibanga eliyinhloko lokushayela lamaloli ahamba isikhathi eside lihambisana namaphoyinti okusebenza ngezilinganiso zokucindezela okukhulu nokugeleza kwesisindo esiphansi.Ukulahleka kwe-aerodynamic ngenxa yama-engeli okugeleza aqinile ku-vaneless diffuser kudlala indima enkulu kulobu bubanzi bokusebenza.
