Amanothi okufunda we-turbocharger theory

Imephu entsha isuselwe ekusetshenzisweni kwamapharamitha alondolozayo njengamandla e-turbocharger nokugeleza kwesisindo se-turbine ukuchaza ukusebenza kwe-turbine kuzo zonke izindawo ze-VGT.Amajika atholiwe afakwe ngokunembile ama-polynomials angama-quadratic futhi amasu alula wokuhumusha anikeza imiphumela ethembekile.

Ukwehlisa kuwumkhuba ekuthuthukisweni kwenjini okuvumela ukusebenza kahle okungcono kanye nokukhithika okuphansi okususelwe ekwandeni kokukhishwa kwamandla ezinjinini ezincishisiwe ezigudlwayo.Ukuze kuzuzwe lokhu okukhiphayo okuphezulu kuyadingeka ukwandisa ingcindezi yokukhulisa.Kule minyaka eyishumi edlule, ubuchwepheshe be-geometry turbocharger (VGT) obuguquguqukayo busabalele kukho konke ukususwa kwezinjini nazo zonke izingxenye zemakethe, futhi namuhla, ubuchwepheshe obusha be-turbocharging buyahlolwa njengama-compressor wejometri aguquguqukayo, izinjini ezi-turbocharged ngokulandelana noma izinjini ezicindezelwe izigaba ezimbili.

Idizayini efanele kanye nokuhlangana kwesistimu ye-turbocharging enjinini evuthayo yangaphakathi inokubaluleka kwezimali zokuziphatha okufanele kwayo yonke injini.Ngokuqondile, ibalulekile enqubweni yokushintshisana ngegesi kanye nangesikhathi sokuvela kwenjini kwesikhashana, futhi izoba nomthelela ngendlela ebalulekile ekusetshenzisweni okuqondile kwenjini kanye nokukhipha ukungcola.

Izici ze-turbine zifakwe ngokunembile imisebenzi ye-quadratic polynomial.Le misebenzi inezici okufanele ihlukaniseke ngokuqhubekayo futhi ngaphandle kokuyekwa.Umehluko phakathi kokuziphatha kwama-turbine ngaphansi kwezimo zokugeleza ezizinzile noma ezinyakazayo, kanye nezimo zokudlulisa ukushisa kuyo yonke i-turbine kusaphenywa.Namuhla, asikho isixazululo esilula sokuxazulula lezi zinkinga ngamakhodi e-0D.Isethulo esisha sisebenzisa amapharamitha alandelanayo angazweli kakhulu emiphumeleni yawo.Ngakho-ke imiphumela ehlanganisiwe inokwethenjelwa kakhulu futhi ukunemba kwawo wonke ukumbumbuluzwa kwenjini kuyathuthukiswa.
