Ukukhetha i-turbocharger efanelekileyo kwi-injini yakho kubandakanya izinto ezininzi zokucinga.
Ayizizo iinyani kuphela eziyimfuneko malunga ne-injini yakho ethile, kodwa kubaluleke ngokulinganayo kusetyenziso olucetyiweyo 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, umyinge wokuqukuqela komoya womthamo womoya, ngokuchasene nesakhono sayo.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 kwevolumu.Kwi-injini ye-turbocharged, ixesha lisanciphisa ukuba ivalve yokungena ivule kangakanani, kodwa ukuba uxinzelelo lokuthatha lukhulu kunoxinzelelo lwe-atmospheric (lonyusiwe), 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 imveliso yamandla ehashe elipheleleyo, 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 ubala umdlalo we-turbo ofanelekileyo, i-VE yinto ebalulekileyo ekufuneka iqwalaselwe, njengoko inegalelo elibalulekileyo ekumiseleni imfuno yokuhamba komoya yenjini enikiweyo.
eShanghaiSHOU YUANunamavaumthengisi we-aftermarket turbocharger kunye namalungu, eyatsala inani elikhulu labathengi abavela kumazwe ahlukeneyo kwiimarike zamazwe ngamazwe.Kukho abathengi abaninzi abanelisekile ngeemveliso zethu kwaye baphinde bathenge rhoqo ngenyanga.Iminyaka yethu engama-20 yamava kwishishini le-turbo inokukubonelela ngeemveliso ezikumgangatho ophezulu kunye nenkonzo yokumamela emva kokuthengisa.Sinoluhlu olubanzi lweendidi zemveliso, kuqukaivili lomoya, ivili compressor, indlu yecompressor, I-CHRA, njl. Ngoko ke, ungaqhagamshelana nathi ukuba ufuna naziphi na iinxalenye ze-turbocharger.
