Mepu nyowani yakavakirwa pakushandiswa kweanochengetedza ma paramita se turbocharger simba uye turbine mass flow kutsanangura mashandiro eturbine munzvimbo dzese dzeVGT. Iwo macurves anowanikwa akanyatso kurongedzerwa nequadratic polynomials uye nyore kududzira matekiniki anopa mhedzisiro yakavimbika.
Kudzikisira itsika mukusimudzira injini inobvumira kushanda zvakanaka uye kuderera kwehutsi zvichibva pakuwedzera kwekubuda kwemagetsi mumajini ekudzikisira. Kuti uwane ichi chakakwira kuburitsa kunodiwa kuwedzera boosting pressure. Mumakore gumi apfuura, tekinoroji yejiometry turbocharger (VGT) matekinoroji akapararira kune ese ekudzimisa injini uye zvikamu zvese zvemusika, uye mazuva ano, matekinoroji matsva eturbocharging akaongororwa seachinja geometry compressors, sequentially turbocharged injini kana maviri-nhanho akadzvanywa injini.
Iyo chaiyo dhizaini uye kubatana kweiyo turbocharging system kune yemukati combustion injini ine capital kukosha kweiyo chaiyo maitiro einjini yese. Kunyanya, yakakosha mukuchinjana kwegasi uye panguva yekuchinja kweinjini, uye ichapesvedzera nenzira yakakosha iyo injini yekushandisa uye kuburitsa zvinosvibisa.
Iwo turbine maitiro akanyatso kurongedzerwa ne quadratic polynomial mabasa. Aya mabasa ane hunhu hwekuramba achisiyaniswa uye pasina discontinuities. Misiyano pakati pemafambiro eturbines pasi pekudzikama kana pasi pemamiriro ekuyerera, pamwe chete nemamiriro ekutamisa kupisa mukati meturbine zvichiri kuongororwa. Mazuva ano, haisipo mhinduro iri nyore yekugadzirisa matambudziko aya mu0D makodhi. Iyo nyowani inomiririra inoshandisa inochengetedza parameter iyo isinganyanyi kutarisisa kune yavo mhedzisiro. Saka iyo yakapindirwa mhedzisiro inovimbika uye kurongeka kwese injini simulation inovandudzwa.
