Ukukhetha i-turbocharger efanelekile yenjini yakho kubandakanya ukucatshangelwa okuningi.
Akugcini nje kuphela ngamaqiniso nge-Injini yakho ethile edingekayo, kepha ebaluleke ngokulinganayo ukusetshenziswa okuhlosiwe kwaleyo njini. Indlela ebaluleke kunazo zonke kulokhu kucatshangelwa kuyindlela enengqondo ingqondo. Ngamanye amagama, uma u-turbocharging injini ekalwa njengamanje ku-HP angama-200 ngefomu layo elifile ngokwemvelo, cishe uzothanda ukuba nayo ikhiqiza i-600 HP. Kodwa-ke, lokho kungahle kube ngaphakathi ngaphakathi kweqoqo elengeziwe lokuguqulwa ohlose ukukwenza. Uma ufuna ukukhuphuka kwamandla okuhle kokushayela komgwaqo okuzungezile, ukukhuphuka kwamaphesenti angama-50 kungokoqobo futhi kuhambelana ne-turbo kuleli zinga lokukhuphuka kuzokhiqiza imiphumela egculisayo. Ukwanda kwamandla kagesi angama-300 (ama-200 kuye kwangama-600 hp) kungenzeka ezinjini eziningi, kepha kukhuphuka njengokugcina okubekelwe izinjini zokuncintisana ezinokuhlelwa kokuguqulwa okwengeziwe, kokubili kwangaphandle, konke kusebenza ngokubambisana ukufeza leli zinga lamandla. Enye yezinto ezibaluleke kakhulu ekunqumeni ukuthi iyiphi i-turbocharger efanelekile kakhulu ukuthi ube ne-Horsepower yakho engqondweni. Kepha kufanele ube namaqiniso ngalokho okudubulayo.
Isicelo kanye nokusetshenziswa okuhlosiwe kwemoto kubaluleke kakhulu futhi. Imoto ye-autocross, ngokwesibonelo, ibingadinga ukukhuphuka okusheshayo kokusheshisa okusheshayo, kanti imoto ye-bonneville esebenza ama-expes amade ikhathazekile kakhulu nge-Horsepower ngejubane eliphakeme le-horsepower. Izimoto ezi-Indy zivame ukuguqula i-turbo ukuthola amathrekhi amafushane ngokuqhathanisa amathrekhi amade ngenxa yokuthi umdlalo we-turbo ubaluleke kangakanani ukugeleza nge-injini ethile nejubane lemoto. Izicelo zokudonsa ugandaganda zizobona ijubane eliphakeme kakhulu le-Injini ekuqaleni komncintiswano, futhi njengoba ukudonswa kuqhubeka, umthwalo uthuthuke kancane kancane njenge-brony brake kuze kube yilapho injini igcwele isilayidi. Lokhu kusetshenziswa okuhlukile kudinga umentshisi ohlukile we-turbo.
Igama elisebenza kahle, noma ve, yisikhathi esibaluleke kakhulu nomqondo okufanele uqonde. Khulisa injini ikhulisa amandla e-horsepower ne-RPM. Ngaphandle kokuguqulwa kwamafutha nokulahla, iningi lezingxenye zendabuko zendabuko eziphakeme kakhulu ziphakamisa injini. Ukungeniswa komoya okuphoqelelwe konke kumayelana nokwanda ve. Kepha kuyini ukusebenza kahle kwevolumetric?
Injini yenjini ukuqhathanisa injini ebaliwe, noma ye-moumetric flow rate, i-volumetric air of air, iqhathanisa namandla ayo angempela. Injini inokuthunyelwa okuhleliwe, ngokwesibonelo, amasentimitha angama-300. Ukuxoshwa kuzogeleza ngokweqiniso i-300 CI njalo enjini yokuvukelwa kwezinjini ezimbili (injini enama-stroke kufanele ajikeleze kabili kuwo wonke ama-cylinders ukuqedela yonke imijikelezo emine). Ngomqondo othile, kuzoba nobudlelwano obuqondile ne-Airflow kanye ne-Injini RPM lapho kuphindeka kabili izinguquko ngomzuzu kungaphindwa khona umoya osuswa yinjini. Uma injini ikwazi ukugeleza kahle umoya omningi ngesikhathi sokusebenza njengoba ukubalwa kwethiyori kuthi kungenzeka, lelo njini lingaba nephesenti le-100. Kodwa-ke, eqinisweni lokho kwenzeka.
Ngenkathi kunezinjini ezithile ezifinyelela amaphesenti ayi-100 noma ngaphezulu, iningi alikwenzi. Kunezici eziningi ezivimbela amandla enjini yokuhlangana nokusebenza kahle kwamaphesenti ayi-100, ezinye ngenhloso, ezinye zingenakugwenywa. Isibonelo, izindlu zokuhlanza umoya kanye nokuhlunga kuzokuvimbela ukungena komoya, kepha awufuni ukusebenzisa injini yakho ngaphandle kokuhlunga komoya.
Isizathu se-turbocharging sinomthelela omkhulu omangalisayo ekusebenzeni kwenjini kungaqondwa kangcono kusetshenziswa lo mqondo wokusebenza kahle kwevolumetric. Ku-turbocharged injini, isikhathi namanje sivimbela isikhathi esingakanani i-valve yokudla sivulekile, kepha uma ingcindezi yokudla inkulu kakhulu kunengcindezi yomkhathi (okuqiniswa), khona-ke singaphoqa inani levolumu yomoya ephelele phakathi kwe-valve ukuvula. Ikhwalithi yalolo moya ithuthukisiwe ngezinhloso zokuhlanganisa ngoba ubuningi bayo buye banda. Inhlanganisela yokuthuthuka kwengcindezi kanye ne-aunsity yomoya isinxephezelo ngesici esinqunyelwe isikhathi semicimbi ye-valve futhi sivumele izinjini ezikhulisa ukufezekisa ngaphezulu kwe-100% ve. Kepha lapho kwandise okuphelele kwemiphumela yehhashi eliphelele, izinjini ezi-turbocharged zizohlomula ekuthuthukisweni okuningi okufanayo okwenziwe ukuthuthukisa izinjini ezifiselekayo ngokwemvelo.
Njengoba kushiwo ngenhla, injini enikeziwe izoba ngcono noma okubi kakhulu ngaphezulu kweqembu le-RPM. Yonke injini izoba nendawo yayo emnandi, okuyiphuzu ekwakhiweni kwenjini lapho, nge-throttle ephelele, ukusebenza kahle kwevolumetric kuphezulu kakhulu. Lokhu ngokuvamile kuliqiniso lapho i-torque ephakeme izotholakala kwijika le-torque. Kusukela ve izoba sendaweni yayo ephezulu kakhulu, ukusebenza kahle kwamafutha noma i-BSFC, kulinganiswe ngamakhilogremu kaphethiloli ngehhashi ngalinye lamahhashi, ngehora, nakho kuzoba nokusebenza kwayo okuphezulu. Lapho ubala umdlalo ofanele we-turbo, ve kuyinto ebalulekile okufanele uyicabangele, ngoba kunomthelela obalulekile ekunqumeni ukufunwa kwe-airflow yenjini enikeziwe.
UShanghaiShou yuanungonolwaziumphakeli we-aftermarket turbocharger nezingxenye, eheha amakhasimende amaningi avela emazweni ahlukene emakethe yamazwe aphesheya. Kunamakhasimende amaningi anelisekile ngemikhiqizo yethu futhi ahlenge kabusha njalo ngenyanga. Iminyaka yethu engama-20 yesipiliyoni eTurbo Fact ingakunikeza ngemikhiqizo esezingeni eliphakeme nensizakalo yokulalela ngemuva kokunaka. Sinezigaba ezahlukahlukene zomkhiqizo, kufaka phakathiisondo le-turbine, isondo le-compressor, Izindlu zeCompressor, Chra, Ngakho-ke, ngakho-ke, ungaxhumana nathi uma ufuna noma yiziphi izingxenye zama-turbocharger.
