Kodi turbo yosinthika ya geometry ndi chiyani ndipo imagwira ntchito bwanji?
Zamkatimu
Ngati mukufuna kuyankha kochulukirapo kuchokera ku turbo yanu osapereka mphamvu pachimake, turbo yosinthika ya geometry ikhoza kukhala yomwe mukufuna. Apa tikuwuzani chomwe VGT ndi momwe imagwirira ntchito, komanso ubwino wake pa turbocharger yokhazikika ya geometry.
Turbocharger ndi zabwino chifukwa amayamwa mphamvu zapathengo ndi ntchito kuonjezera injini mphamvu. Variable Geometry Turbocharger ndi mtundu wapamwamba kwambiri waukadaulo womwe umapereka maubwino angapo komanso kuchuluka kwazovuta. Chifukwa cha kanema wopangidwa ndi KF Turbo pa Instagram, tidayang'ana mwatsatanetsatane zomwe zimapangitsa kuti geometry turbo ikhale yapadera kwambiri.
Kodi variable geometry turbocharger imagwira ntchito bwanji?
Kanemayo akutiwonetsa mkati mwa Vane turbocharger. Amakhala ndi masamba omwe amakonzedwa mozungulira turbine yotulutsa mpweya, yomwe mbali yake imayendetsedwa ndi actuator. Mwachitsanzo, palinso mapangidwe ena okhala ndi zopalasa zomwe zimayenda mmwamba ndi pansi; amapezeka kwambiri m'makina olemera kwambiri monga magalimoto kapena magalimoto ena akuluakulu.
Kodi pali kusiyana kotani pakati pa fixed geometry turbocharger?
Mu turbocharger yokhazikika ya geometry, mipweya yotulutsa mpweya imadutsa mu turbine ndikuyizungulira, yomwe imazungulira kompresa yolumikizidwa yomwe imapangitsa kuti injini ikhale yolimba. Pa RPM yotsika, injini sipanga mpweya wokwanira kuti uzungulire turbine ndikupanga milingo yayikulu yolimbikitsira. Panthawiyi, dongosololi likunenedwa kuti liri pansi pa chiwongolero chowonjezera.
Injini ikafika pa RPM yokwera mokwanira kuti ipangitse kuthamanga, zimatengerabe nthawi kuti izungulire injiniyo kuti ifike pa liwiro loyenera; izi zimatchedwa turbo lag. Turbo lag ndi boost threshold ndizokwera kwa ma turbo akuluakulu omwe amafunikira mphamvu zambiri kuti azizungulira. Komabe, ma turbine othamanga apamwambawa amatha kupanga mphamvu zambiri. Ndi kunyengerera, monga zinthu zina zambiri zamainjiniya.
Kodi ubwino wa geometry turbocharger ndi chiyani?
Kusintha kwa geometry turbocharger ikufuna kusintha izi powonjezera vanes kapena zinthu zina zomwe zimagwira ntchito kusintha geometry ya turbine system. Mu turbocharger yozungulira ngati yomwe ikuwonetsedwa pano, mavane amakhala otsekedwa kwambiri ndi liwiro la injini yotsika, zomwe zimalepheretsa kutuluka kwa mpweya wotuluka kupita ku mavane. Kuchepetsa uku kumawonjezera kuthamanga kwa mpweya, zomwe zimathandiza kuti mpweya wotulutsa mpweya upititse patsogolo turbine mwachangu. Izi zimachepetsa kukwera kwa turbo ndikuchepetsa mphamvu.
RPM chilango
Komabe, kukhala ndi malire otere kungakhale chilango choopsa pa ma RPM apamwamba, pamene injini ikufunika kupopa mpweya wotulutsa mpweya wambiri kuti apange mphamvu. M'derali, mavane amatseguka kuti alole mpweya wotulutsa mpweya wochuluka momwe ungathere kudutsa mu turbocharger, kupewa zoletsa zomwe zingawonjezere kupsinjika kwa msana ndikuchepetsa mphamvu.
Chifukwa chiyani geometry turbocharger ndiyosavuta?
Chifukwa chake injini yosinthika ya geometry turbo ndiyabwino kwambiri padziko lonse lapansi. VGT imatha kupereka mphamvu zambiri popanda kusinthanitsa kwanthawi zonse kwapamwamba kwambiri komanso turbo lag yomwe nthawi zambiri imabwera ndi kukhazikitsidwa kwakukulu kwa turbo. Kugwira bwino ntchito konseko kumapangidwanso bwino, ndipo nthawi zina masamba amatha kugwiritsidwa ntchito ngati mabuleki a injini. Kanemayo ali pansipa ndikufotokozera bwino momwe ukadaulo uwu umagwirira ntchito, wokhala ndi chojambula chothandizira choyera.
