I-Turbo-discharging iyindlela entsha engasebenzisa kangcono amandla atholakala nge-turbineifakwe ku-exhaust flow yezinjini ezivuthayo zangaphakathi.Ukutholwa kabusha kwamandla okushaywa kwe-pulse ngokuhlukaniswa kwamandla okuguquguquka kwe-pulse kuvumela ukuchithwa kwesistimu yokukhipha umoya ukunciphisa umsebenzi wokupompa injini nokuthuthukisa ukonga kukaphethiloli wenjini.Lena indlela entsha yokuthuthukisa uhlelo lomoya esike yafundelwa izinjini ngokwemvelo.Kodwa-ke, ukuze kuphumelele, ukuchithwa kwe-turbo kufanele kusebenze ezinjinini ezine-turbocharged, njengoba ukwehlisa kuyindlela ethembisayo yamasistimu esitimela samandla esizayo.
Ezinye izifundo zisebenzisa imodeli yegesi enohlangothi olulodwa ukuhlola umthelela wokukhishwa kwe-turbo enjinini kaphethiloli ene-turbocharged, ikakhulukazi egxile ekusebenzelaneni nohlelo lokushaja kwe-turbo.Imiphumela ibonisa ukuthi i-torque yenjini ephakeme kakhulu ikhushulwa ngesivinini esiphansi ukuya maphakathi ne-torque yejubane encishiswe kancane ngenxa yemikhawulo yokuphefumula kwenjini ngamavalvu okukhipha umoya ophakeme.I-torque ephezulu yenjini njengomsebenzi wejubane ene-turbocharger enkulu kanye ne-turbo-discharging iqhathaniswe naleyo ye-turbocharger encane ngaphandle kokukhipha i-turbo.Ukuthuthukiswa komnotho kaphethiloli kubonakale ezindaweni eziningi ezigcwele ingxenye yemephu yenjini, ngamavelu aphezulu ahluka ukusuka ku-2 ukuya ku-7% kuye ngesu lesisekelo lenjini yomoya.Isisindo sensalela esivalelekile esishisayo siye sancishiswa ngokuqhubekayo engxenyeni enkulu yemephu yenjini, ngaphandle kwezimo zamandla aphezulu, lapho umphumela wokwehla komfutho wevalvu wawubusa.Lokhu kulindeleke ukuthi kuvumele inhlansi ithuthuke futhi kuhlomule ukonga uphethiloli.
Imiphumela evela kulolu cwaningo iyethembisa futhi ibonisa ukuthi ukusetshenziswa kwamanye amandla e-exhaust gas atholakalayo ukuze kukhishwe i-turbo-discharging esikhundleni se-turbocharging kungaba nomthelela omuhle kukho kokubili ukulayisha okuyingxenye kanye nokusebenza kwenjini egcwele.Kusenamandla abalulekile okuqhubeka nokusebenza kahle ngokusetshenziswa kwe-valve actuation eguquguqukayo kanye nezinhlelo zokulawula i-turbocharger.
