Ukukhetha i-turbocharger efanelekileyo kwi-injini yakho kubandakanya izinto ezininzi zokucinga.
Ayizizo iinyani kuphela eziyimfuneko malunga ne-injini yakho ethile, kodwa kubaluleke ngokulinganayo kusetyenziso olucetywayo lwaloo njini. Eyona ndlela ibalulekileyo yokujonga ezi ngqwalasela yingqondo eyinyani. Ngamanye amazwi, ukuba utshaja i-injini ngoku ilinganiswe kwi-200 hp ngendlela enqwenelwa ngayo ngokwendalo, ungathanda ukuba ivelise i-600 hp. Nangona kunjalo, oko kunokuba yinto engenakwenzeka ngaphakathi kwingqokelela eyongezelelweyo yohlengahlengiso oceba ukuzenza. Ukuba ujonge ukonyuswa kwamandla okuhle kuwo wonke umqhubi wesitrato, ukonyuka kweepesenti ezingama-50 kunokwenyani kwaye ukuthelekisa i-turbo kweli nqanaba lokunyuka kuya kuvelisa iziphumo ezanelisayo. Ukunyuka kwamandla epesenti ye-300 (200 ukuya kwi-600 hp) kunokwenzeka kwiinjini ezininzi, kodwa ukunyuka okunje kugcinelwe iinjini zokhuphiswano ezinoluhlu lwezilungiso ezongezelelweyo, ngaphakathi nangaphandle, ukuba zonke zisebenza kunye ukuphumeza eli nqanaba lamandla. Enye yezona zinto zibalulekileyo ekumiseleni ukuba yeyiphi i-turbocharger eyona ifanelekileyo kukuba namandla ojolise kuwo engqondweni. Kodwa kufuneka ube nenyani malunga nale nto uyidubulelayo.
Ukusetyenziswa kunye nenjongo yokusetyenziswa kwesithuthi kubaluleke kakhulu. Imoto ye-autocross, umzekelo, inokufuna ukonyuswa okukhawulezayo kwesantya esikhawulezayo, ngelixa imoto yaseBonneville ebaleka imiqolo emide ixhalabele amandla ehashe kwizantya eziphezulu zenjini. Iimoto ze-Indy zihlala zihlengahlengisa i-turbo yeengoma ezimfutshane ngokuchasene neengoma ezinde ngenxa yokubaluleka komdlalo we-turbo ukunyusa ukuhamba kwe-injini kunye nezantya zemoto. Usetyenziso lokutsalwa kwetrektara luyakubona esona santya siphezulu se-injini kanye ekuqaleni kokhuphiswano, kwaye njengoko utsalo luqhubela phambili, umthwalo uye unyuswe ngokuqhubekayo ngokufana ne-prony brake de injini ilayishwe phezulu sisileyi sokutsala. Olu setyenziso lwahlukeneyo lufuna ukuhambelana kwe-turbo eyahlukileyo.
Igama elithi Volumetric Efficiency, okanye iVE, ligama elibaluleke kakhulu kunye nengqiqo ekufuneka iqondwe. Ukunyusa i-injini ye-VE iphakamisa amandla ayo ehashe kunye ne-RPM. Ngaphandle kwamafutha kunye nohlengahlengiso lomlilo, uninzi lweendawo ze-injini ezisebenza ngasemva ezikumgangatho ophezulu ziphakamisa i-VE ye-injini. Ukuqaliswa ngenkani komoya konke malunga nokunyusa iVE. Kodwa yintoni iVolumetric Efficiency ngokuchanekileyo?
I-VE ye-injini luthelekiso lwe-injini yokubalwa, okanye ithiyori, isantya sokuqukuqela komoya womthamo womoya, xa kuthelekiswa namandla ayo okwenene. I-injini ine-displacement esisigxina, umzekelo, ii-cubic intshi ezingama-300. Oko kugxothwa kuya kuhamba ngokwethiyori 300 ci nganye iirevolutions ezimbini ze-injini (i-injini ene-stroke emine kufuneka ijikelezise kabini kuzo zonke iisilinda ukugqiba yonke imijikelo emine). Kwithiyori, kuya kubakho unxibelelwano oluhambelana nokuhamba komoya kunye ne-injini ye-RPM apho ukuphinda-phinda uhlaziyo ngomzuzu kuya kuphinda kabini umoya osuswe yi-injini. Ukuba i-injini ikwazile ukuqukuqela kanye kanye njengomoya omninzi ngexesha lokusebenza njengoko ubalo lwethiyori luthi lunokwenzeka, loo njini iya kuba ne-VE ye-100 ekhulwini. Nangona kunjalo, enyanisweni oko kunqabile.
Ngelixa kukho iinjini ezifikelela kwi-100 yeepesenti okanye ngaphezulu kwe-VE, uninzi alwenzi. Kukho izinto ezininzi ezithintela amandla e-injini ukuhlangabezana ne-100 lepesenti ye-volumetric ye-volumetric, ezinye zenziwe ngabom, ezinye zingenakuthintelwa. Umzekelo indlu yesicoci somoya kunye nesihluzi siya kuthi sithintele ukuhamba komoya, kodwa awufuni ukusebenzisa injini yakho ngaphandle kohluzo lomoya.
Isizathu sokuba i-turbocharging inefuthe elimangalisayo ekusebenzeni kwe-injini kunokuqondwa ngcono kusetyenziswa le ngcamango yokusebenza kakuhle kwevolumetric. Kwi-injini ye-turbocharged, ixesha lisanciphisa ukuba ivalve yokungena ivulekile ixesha elingakanani, kodwa ukuba uxinzelelo lokuthatha lukhulu kunoxinzelelo lwe-atmospheric (lonyuswe), ngoko sinokunyanzelisa umthamo womoya opheleleyo ngexesha lokuvulwa kwevalve. Umgangatho waloo moya uphuculwe ngeenjongo zokutsha kuba ukuxinana kwawo kuye kwandiswa. Ukudityaniswa koxinzelelo lwe-boost kunye noxinzelelo lomoya kuhlawulela umba wokunciphisa ixesha leziganeko zevalvu kwaye uvumele iinjini ezongeziweyo ukuba zifezekise kakuhle ngaphezulu kwe-100% VE. Kodwa xa kunyuswa isiphumo samandla ehashe, neenjini ze-turbocharged ziya kuxhamla kuninzi loyilo oluphuculweyo olwenziweyo ukomeleza i-VE kwiinjini ezinqwenelekayo ngokwendalo.
Njengoko kukhankanyiwe ngasentla, injini enikiweyo iya kuba ngcono okanye embi ngakumbi iVE ngaphezulu kwebhendi yeRPM. I-injini nganye iya kuba nendawo yayo emnandi, eyona nto iphambili kuyilo lwe-injini apho, xa i-throttle epheleleyo, ukusebenza kwe-volumetric kuphezulu. Le yeyona ndawo apho i-torque ephezulu iya kufumaneka kwigophe letorque. Kuba i-VE iya kuba kwinqanaba eliphezulu, ukusebenza kakuhle kwe-fuel okanye i-BSFC, elinganiselwa kwiipounds zamafutha ngehashe ngalinye, ngeyure, iya kuba kumgangatho ophezulu wokusebenza kwayo. Xa kubalwa umdlalo ofanelekileyo we-turbo, iVE yinto ebalulekileyo ekufuneka iqwalaselwe, njengoko inegalelo elibalulekileyo ekumiseleni imfuno yokuhamba komoya yenjini enikiweyo.
eShanghaiSHOU YUANngumntu onamavaumthengisi we-aftermarket turbocharger kunye namalungu, eyatsala inani elikhulu labathengi abavela kumazwe ahlukeneyo kwiimarike zamazwe ngamazwe.
