Kodi bi-turbo kapena parallel boost ndi chiyani? [utsogoleri]

Okonza ma V-injini angakhale ndi vuto lalikulu kuwakakamiza ndi turbocharger imodzi. Ndicho chifukwa chake njira yowonjezera yowonjezera imagwiritsidwa ntchito nthawi zambiri, i.e. bi-turbo. Ine ndikufotokoza chomwe icho chiri.

turbocharger iliyonse imakhala ndi inertia chifukwa cha kuchuluka kwa rotor, yomwe iyenera kufulumizitsidwa ndi mpweya wotulutsa mpweya. Mipweya yotulutsa mpweya isanakwane liwiro lokwanira kutsitsimutsa injini, zomwe zimatchedwa turbo lag zimachitika. Ndinalemba zambiri za chodabwitsa ichi m'mawu okhudza kusintha kwa geometry ya turbocharger. Kuti timvetsetse nkhani yomwe ili pansipa, ndikwanira kudziwa kuti mphamvu zomwe tikufuna kapena kukula kwa injini, timafunikira turbocharger, koma zazikulu, zimakhala zovuta kuzilamulira, zomwe zikutanthauza kuchedwa kwambiri. poyankha gasi.

Awiri mmalo mwa mmodzi, ndiwo. bi-turbo

Kwa Amereka, vuto la supercharging V-injini linathetsedwa kalekale, chifukwa adagwiritsa ntchito njira yosavuta yothetsera, i.e. kompresa yoyendetsedwa molunjika kuchokera ku crankshaft. Chida chachikulu champhamvu kwambiri chilibe vuto la turbo lag chifukwa sichimayendetsedwa ndi mpweya wotulutsa mpweya. Chinthu china n'chakuti, ngakhale supercharging, injini akadali makhalidwe a mumlengalenga, chifukwa liwiro kompresa ukuwonjezeka mofanana ndi liwiro la injini. Komabe, mayunitsi aku America alibe vuto ndi magulu othamanga kwambiri chifukwa champhamvu zazikulu.

Zinthu zinali zosiyana kotheratu ku Europe kapena Japan, komwe timagulu tating'ono timalamulira, ngakhale ndi V6 kapena V8. Amagwira ntchito bwino ndi turbocharger, koma apa vuto lagona pakugwira ntchito kwa mabanki awiri a silinda ndi turbocharger imodzi. Kuti mupereke mpweya wokwanira ndikuwonjezera kuthamanga, kumangofunika kukhala kwakukulu. Ndipo monga tikudziwira kale, chachikulu chimatanthauza vuto ndi turbo lag.

Chifukwa chake, nkhaniyi idathetsedwa ndi dongosolo la bi-turbo. Zimapangidwa ndi kukonza mitu iwiri ya V-injini padera ndikusintha turbocharger yoyenera kwa iliyonse. Pankhani ya injini monga V6, tikulankhula za turbocharger yomwe imangogwira masilindala atatu, motero ndi yaying'ono. Mzere wachiwiri wa masilindala umatumizidwa ndi yachiwiri, yofanana ndi turbocharger.

Chifukwa chake, mwachidule, dongosolo la jakisoni lofananira silili kanthu koma ma turbocharger omwewo omwe amatumikira mzere umodzi wa masilindala mu injini yokhala ndi mitu iwiri (yoboola ngati V kapena yotsutsana). Ndizotheka mwaukadaulo kugwiritsa ntchito kulipiritsa kofananira kwa ma in-line unit, koma nthawi ngati izi, parallel charging system, yomwe imadziwikanso kuti twin-turbo, imagwira ntchito bwino. Komabe, injini zina za BMW 6-cylinder ndizofanana kwambiri, ndipo turbocharger iliyonse imakhala ndi masilinda atatu.

Vuto lamutu

Bi-turbo nomenclature imagwiritsidwa ntchito pakuyitanitsa kofananira, koma opanga magalimoto ndi injini samatsata lamuloli nthawi zonse. Dzina lakuti bi-turbo limagwiritsidwanso ntchito nthawi zambiri pakupanga zotsatizana, zomwe zimatchedwa. Makanema atali pa TV. Choncho, n'zosatheka kudalira mayina a makampani a galimoto kuti azindikire mtundu wa supercharging. Nomenclature yokhayo yomwe ilibe chikayikiro ndi zowonjezera ndi zofanana.
