Ukusetyenziswa kwe-turbocharging kwiinjini zokutsha zangaphakathi kubalulekile ukuze kuhlangatyezwane neemfuno zamandla zamva nje kunye nokukhutshwa kweenjini ezinkulu zedizili kunye negesi.Ukuze kuzuzwe
ukuguquguquka okufunekayo, i-turbocharger inokuyilwa nokuba ibe neendawo zokudlula kunye namasango enkunkuma, okanye ngeejiyometri zeturbine eziguquguqukayo ngokupheleleyo (VGT).Ukusetyenziswa kwamasango enkunkuma kuyonakalisa ukusebenza kwe-turbocharger kodwa kubonelela ngesisombululo esingabizi kakhulu kwaye esomeleleyo sokwahluka okufunekayo.Iinkqubo eziqhelekileyo zeVGT zifuna inani elikhulu lamacandelo apho umlomo ngamnye ushukunyiswa ngokuzimeleyo ngeringi ye-actuation kwaye ngamanye amaxesha ngengalo ye-lever.
Ngaphandle kobunzima bazo, i-VGT turbocharging ibonelela ngeenzuzo ezibalulekileyo xa kuthelekiswa ne-fixed geometry turbocharger ehambelanayo.
nokuba kumthwalo ogcweleyo, ukushiya isikhewu kwizicelo zokulayisha inxalenye, okanye zithelekiswe ngomthwalo ongaphelelanga kwaye zifuna isango lenkunkuma.Upapasho luchaza imfuno yokuba nomlomo onokuthi ushenxise i-axially ukulungiselela ubukho beediphozithi kunye nokwandiswa kwe-thermal ukukhusela i-blade ukuba ingaxingi.Iinkqubo eziqhelekileyo zeVGT azizange zisetyenziswe ngokubanzi kwizicelo apho amandla aphezulu, ukuthembeka okuphezulu kunye nobomi obude bufunekayo ngenxa yeendleko kunye nezizathu ezintsonkothileyo, kwaye ngenxa yesi sizathu uphuhliso oluninzi luye lwaqulunqwa ukuphumeza i-turbocharger yeVGT kunye noyilo olulula kunye namalungu ahamba ngaphantsi. .
Lo msebenzi uphakamisa ingqikelelo entsha ye-geometry turbocharger nozzle enokuthi isetyenziswe kwi-axial kunye ne-radial turbocharger kuqwalaselo.Ingcinga inikezela ngokuncipha okubonakalayo kweendawo ezihambayo kwaye ke ngoko inamandla okunciphisa iindleko ze-turbocharger kunye nokwandisa ukuthembeka kwayo xa kuthelekiswa noyilo lweVGT oluqhelekileyo.Ingqikelelo ibandakanya umlomo oyintloko kunye nombhobho we-tandem.Nganye yale mibhobho iyindandatho enenani elifunekayo leevane.Ngokukhupha i-nozzle enye ngokubhekiselele kwenye, kunokwenzeka ukuguqula i-angle yokuphuma kwe-engile ye-nozzle, kwaye uguqule indawo yomqala ngendlela eyahluka ngayo ukuhamba kobunzima obudlula kwi-nozzle.
