Zolemba zowerengera za turbocharger

Padziko lonse lapansi, cholinga chachikulu ndikuwongolera chuma chamafuta popanda kudzipereka pokhudzana ndi machitidwe ena aliwonse. Pachiyambi choyamba, kafukufuku wapameter wa ma diffuser akuwonetsa kuti kukonza bwino m'malo ogwirira ntchito ndikotheka pamtengo wocheperako kukula kwa mapu. Kumaliza kuchokera pazotsatira ma geometri atatu osinthika omwe ali ndi zovuta zosiyanasiyana kutengera ma diffusers okhala ndi mawonekedwe amapangidwa. Zotsatira zochokera kumalo oyesera gasi ndi makina oyesera a injini zikuwonetsa kuti makina onse amatha kukulitsa mphamvu ya kompresa motero amapangitsa kuti mafuta azichulukirachulukira pama injini olemera kwambiri.

Zovuta zowonjezera zimayimiridwa ndi kufunikira kwa kulimba kwambiri, kutulutsa phokoso lochepa komanso kuchita bwino kwakanthawi kwa injini. Chifukwa chake, mapangidwe a compressor system nthawi zonse amakhala osagwirizana pakati pakuchita bwino kwambiri, kutalika kwa mapu otakata, kulemera kochepa kwa chowongolera komanso kulimba kwambiri komwe kumatsogolera kumagawo a compressor ndi kutayika kwakukulu kwa ndege pamagalimoto oyenda nthawi yayitali ndipo motero, kuchepa kwa chuma chamafuta. Kuthetsa vuto lalikululi la kapangidwe ka kompresa poyambitsa ma geometry osinthika kumatha kubweretsa kutsika kwamitengo ya umwini yomwe ndi malo ogulitsa kwambiri okhudzana ndi ntchito zolemetsa. Kupatula ma valve obwereza omwe amagwiritsidwa ntchito m'ma turbocharger agalimoto, ma compressor okhala ndi geometry yosinthika sanapeze njira yawo yopanga mndandanda ngakhale kafukufuku wozama wachitika pankhaniyi.

Ma compressor atatu osinthika apangidwa ndi cholinga chokweza kuchuluka kwamafuta amafuta a injini zolemetsa pamagalimoto akuluakulu popanda kuwonongeka kokhudzana ndi mphamvu zovotera, torque yapamwamba, kukhazikika kwamphamvu komanso kulimba. Pachiyambi choyamba, zofunikira za injini pokhudzana ndi gawo la compressor zatengedwa ndipo malo ogwiritsira ntchito compressor oyenera kwambiri amadziwika. Magalimoto akuluakulu oyendetsa magalimoto aatali amafanana ndi malo ogwiritsira ntchito pazitsulo zothamanga kwambiri komanso kuyenda kochepa. Kutayika kwa ma aerodynamic chifukwa cha mafunde othamanga kwambiri mu vaneless diffuser kumachita gawo lalikulu pamachitidwe awa.
