Ukukhetha i-turbocharger efanele yenjini yakho kuhlanganisa izinto eziningi.
Akuwona kuphela amaqiniso mayelana nenjini yakho ethile adingekayo, kodwa kubaluleke ngokulinganayo ukusetshenziswa okuhlosiwe kwaleyo njini.Indlela ebaluleke kakhulu kulokhu kucatshangelwa umqondo ongokoqobo.Ngamanye amazwi, uma usebenzisa i-turbocharging injini okwamanje ekalwe ku-200 hp ngendlela efisa ngayo ngokwemvelo, ungathanda ukuthi ikhiqize u-600 hp.Kodwa-ke, lokho kungase kungabi ngokoqobo ngaphakathi kweqoqo elingeziwe lezinguquko ohlose ukuzenza.Uma ufuna ukukhushulwa kwamandla okuhle kukho konke ukushayela emgwaqeni, ukwenyuka ngamaphesenti angama-50 kuyinto engokoqobo futhi ukufanisa i-turbo naleli zinga lokukhuphuka kuzoveza imiphumela eyanelisa kakhulu.Ukwenyuka kwamandla ngamaphesenti angu-300 (200 kuya ku-600 hp) kungenzeka ezinjinini eziningi, kodwa ukunyuka okunjalo kubekelwe izinjini zokuncintisana ezinoxhaxha lwezinguquko ezengeziwe, kokubili ngaphakathi nangaphandle, ezisebenzisana zonke ukuze kuzuzwe leli zinga lamandla.Enye yezinto ezibaluleke kakhulu ekunqumeni ukuthi iyiphi i-turbocharger efaneleka kakhulu ukuthi ube namandla ehhashi lakho eliqondiwe.Kodwa kufanele ube neqiniso ngalokho okushuthelayo.
Isicelo kanye nokusetshenziswa okuhlosiwe kwemoto nakho kubaluleke kakhulu.Imoto eyi-autocross, isibonelo, ingadinga ukukhuphuka okusheshayo ukuze isheshise, kanti imoto yaseBonneville egijima ama-straights amade ikhathazeke kakhulu ngamandla ehhashi ngesivinini esiphezulu senjini.Izimoto ze-Indy zivame ukulungisa i-turbo yamathrekhi amafushane ngokumelene namathrekhi amade ngenxa yokuthi kubaluleke kangakanani ukufanisa i-turbo ukuze kuthuthukiswe ukugeleza ngesivinini esithile senjini nemoto.Izinhlelo zokudonsa ngogandaganda zizobona isivinini esiphezulu kakhulu senjini ekuqaleni komncintiswano, futhi njengoba ukudonsa kuqhubeka, umthwalo uya ngokuya ukhuphuka ufane nebhuleki le-prony kuze kube yilapho injini ilayishwa kakhulu isihlibhi esidonsayo.Lokhu kusetshenziswa okuhlukile kudinga ukufana okuhlukile kwe-turbo.
Igama elithi Volumetric Efficiency, noma i-VE, liyitemu nomqondo obaluleke kakhulu okufanele uqondwe.Ukwandisa injini ye-VE kuphakamisa amandla ayo amahhashi kanye ne-RPM.Ngaphandle kokuguqulwa kukaphethiloli nokokhela, iningi lezingxenye zenjini ezisebenza kakhulu ezingemuva kwemakethe ezisebenza kakhulu ziphakamisa i-VE yenjini.Ukungeniswa komoya ophoqelelwe kumayelana nokukhulisa i-VE.Kodwa yini i-Volumetric Efficiency ncamashi?
I-VE yenjini iyisiqhathaniso sezinga lokugeleza komoya lenjini elibaliwe, noma lethiyori, uma kuqhathaniswa namandla ayo angempela.Injini ine-displacement engaguquki, isibonelo, ama-cubic amayintshi angu-300.Lokho kususwa kuzogeleza ngokwethiyori ama-300 njalo kuma-revolutions enjini amabili (injini enemivimbo emine kufanele ijikelezise kabili ukuze wonke amasilinda aqede yonke imijikelezo emine).Ngokombono, kuzoba nokuhlobana okuqondile nokugeleza komoya kanye ne-RPM yenjini lapho ukuphinda kabili ukuphenduka ngomzuzu kungaphinda kabili umoya okhishwa injini.Uma injini ikwazile ukugeleza ncamashí umoya omningi ngesikhathi sokusebenza njengoba izibalo zethiyori zisho ukuthi kungenzeka, leyo njini ibingaba ne-VE yamaphesenti angu-100.Nokho, eqinisweni lokho akuvamile ukwenzeka.
Ngenkathi kunezinye izinjini ezithola amaphesenti angu-100 noma ngaphezulu kwe-VE, iningi alikwenzi.Ziningi izinto ezikhinyabeza injini ukuthi ikwazi ukuhlangabezana nomthamo ongu-100% wevolumu, ezinye zenziwe ngamabomu, ezinye azinakugwenywa.Isibonelo indlu nesihlungi sokuhlanza umoya ngokuvamile kuzovimbela ukungena komoya, kodwa awufuni ukusebenzisa injini yakho ngaphandle kokuhlunga komoya.
Isizathu sokuthi i-turbocharging inomthelela omkhulu kangaka ekusebenzeni kwenjini singaqondwa kangcono kusetshenziswa lo mqondo wokusebenza kahle kwevolumu.Enjinini ene-turbocharged, isikhathi sisabeka umkhawulo wokuthi i-valve yokudonsa ivuleke isikhathi esingakanani, kodwa uma ukucindezela kokuthatha kukhulu kunokucindezela komkhathi (okhulisiwe), khona-ke singaphoqelela ivolumu yomoya eyengeziwe phakathi nokuvulwa kwevalvu.Izinga lalowo moya liyathuthukiswa ngenhloso yokuvutha ngoba ukuminyana kwawo kunyukile.Inhlanganisela ye-boost pressure kanye nokuminyana komoya kunxephezela isici esinqunyelwe isikhathi semicimbi yamavalvu futhi ivumela izinjini ezithuthukisiwe ukuthi zithole ngaphezu kuka-100% VE.Kepha uma kukhulisa ukuphuma kwamandla ehhashi okuphelele, ngisho nezinjini ezinama-turbocharged zizohlomula ekuthuthukisweni okuningi okufanayo kwedizayini okwenziwe ukuthuthukisa i-VE ezinjinini ezifiselekayo ngokwemvelo.
Njengoba kushiwo ngenhla, injini enikeziwe izoba ne-VE engcono noma embi kakhulu kunebhendi ye-RPM.Yonke injini izoba nendawo yayo emnandi, okuyiphuzu ekwakhiweni kwenjini lapho, lapho inyakaza, ivolumu yevolumu iba phezulu kakhulu.Lokhu ngokuvamile kuyindawo lapho i-torque ephezulu izotholakala khona ejikeni le-torque.Njengoba i-VE izoba sezingeni eliphezulu kakhulu, ukusebenza kahle kukaphethiloli okuphezulu noma i-BSFC, elinganiswa ngamakhilogremu kaphethiloli ngamandla ehhashi ngalinye, ngehora, nayo izoba sezingeni eliphezulu kakhulu.Lapho kubalwa ukufaniswa kwe-turbo okufanele, i-VE iyinto ebalulekile okufanele icatshangelwe, njengoba inegalelo elibalulekile ekunqumeni isidingo sokugeleza komoya senjini ethile.
ShanghaiSHOU YUANungumuntu onolwaziumphakeli wama-aftermarket turbocharger kanye nezingxenye, ehehe amanani amakhulu amakhasimende avela emazweni ahlukene emakethe yamazwe ngamazwe.Kunamakhasimende amaningi anelisekile ngemikhiqizo yethu futhi athenge kabusha njalo ngenyanga.Iminyaka yethu engama-20 yesipiliyoni embonini ye-turbo ingakunikeza ngemikhiqizo yekhwalithi ephezulu kanye nensizakalo yokuqaphela ngemuva kokuthengisa.Sinezinhlobonhlobo zezigaba zomkhiqizo, okuhlanganisaisondo le-turbine, isondo le-compressor, indawo ye-compressor, I-CHRA, njll. Ngakho-ke, ungaxhumana nathi uma ufuna noma yiziphi izingxenye zama-turbocharger.
