Kugwiritsa ntchito ndi kugwiritsa ntchito valavu yopumira

Ngati ambiri aife timadziwa bwino valve ya Wastegate turbo relief (zambiri apa), valve yothandizira kupanikizika mwachiwonekere sichidziwika bwino ... Chifukwa chiyani? Chabwino, chifukwa ife French timakonda kwambiri dizilo kuti timayiwala za izo. Zoonadi, valavu yothandizirayi imagwiritsidwa ntchito pokhapokha tikakhala ndi thupi lopweteka kuti tilole phokoso, monga momwe zimakhalira ndi mafuta (komanso dizilo, kuti agwiritse ntchito EGR valve, pakati pa zinthu zina). Onani kusiyana pakati pa mafuta ndi dizilo apa. Mosiyana ndi valavu yotetezedwa yodziwika, yotsirizirayi ili pambali yolowera.

Kotero, ngati tikumbukira, tili ndi valavu yotulutsa mpweya kumbali ya utsi, kaya pa petulo kapena dizilo, ndi ina pakumwa pamene ndi injini ya mafuta. Onsewa amagawana mfundo yofanana, koma tidzawatchulabe mayina osiyanasiyana kuti tiwasiyanitse: Wastegate for the exhaust ndi Dampo Valve pomwa. Choncho, dziwani kuti Wastegate imakulolani kuti muwonjezere mphamvu ya injini (ngati tiwonjezera mpweya wolowera mpweya), pamene valavu yotayira imakhala yochepa kuti iteteze turbocharger.

Kugwiritsa ntchito valavu yothandizira

Kutulutsa kumagwiritsidwa ntchito kutembenuza turbocharger mochuluka kapena mocheperapo (potenga mpweya wochuluka kapena wocheperapo) ndipo motero kuti apereke mpweya wochuluka kapena wocheperapo ku doko lolowera: pamene kuchuluka kwake, kuwonjezereka kwa mpweya kumawonjezeka. kupanikizika (wopanikizidwa mu cholowera). Choncho, mpweya wotulutsa mpweya umazungulira turbine, koma ngati titulutsa mpweya wina kuti tichotse, ndiye kuti turbine idzayenda pang'onopang'ono (chifukwa nthawi ino tikugwiritsa ntchito mpweya wotulutsa mpweya, osati onse). Injini ikakhala pamalo otetezeka, Wastegate imatsegulidwa kwathunthu, ndiye kuti timakhala ndi injini yolakalaka mwachilengedwe motero timataya mphamvu. Omwe samamvetsetsa chilichonse ayenera kuyang'ana turbocharger kuchokera kumbali: apa mutha kuwona chithunzi cha ntchito yake.

Kumbali ina, valavu yomwe ilipo pakudya, yomwe imadziwika ndi Dump Valve, imachitanso chimodzimodzi, koma pambali yolowera. Pankhani ya injini ya petulo yokhala ndi valavu yotulutsa mpweya, ndikofunikira kuti mupewe kutuluka kwa mpweya kudzera mu turbine ikatsekedwa kuti valavu ya throttle isasweke, yomwe imalandira kutuluka kwamphamvu kwa mpweya (zingakhale zamanyazi kukhala ndi zigawo mu injini ... Pang'ono monga eni ake a BMW ankadziwa omwe anali ndi mavavu apulasitiki osweka , koma ndi nkhani ina)! Choipa kwambiri, mpweya wothinikizidwa umapangitsa kutembenukira kumayendedwe a turbo turbine ... Zili ngati kukumana ndi mafani awiri maso ndi maso: ndizoipa kwa masamba ngati mphepo ili yamphamvu.

Deceleration gawo

Msonkhano womwe umatulutsa mpweya kunja

Kukhetsa phokoso la valve? Mitundu iwiri?

Zomveka Zomveka za Turbo Flutter ndi Valve Actuation (Bwaaahh Stutututu)

Valavu yolowera mbali iyi imakhala ndi mawu omwe timawadziwa kuchokera m'mafilimu ngati Fast & Furious. Ndipo ngati mu France ali osowa kwambiri mumsewu, ndiye achinyamata Canada (omwe amangoyenda ndi injini mafuta) amakonda zidole zotere, kotero si zachilendo kumeneko - otsika.

Msonkhano wobwerera ku Air inlet

Komabe, palibe phokoso pamene mpweya umabwerera kumalo olowera, kudutsa mu valve throttle: motero, mlatho wopangidwa ndi valve yothandizira kupanikizika umapangidwa. Zingachepetsenso turbo lag pakuyambiranso mathamangitsidwe, chifukwa potulutsa mpweya woponderezedwa womwe udabayidwa, ndiye kuti muyenera kuyika chinthu chonsecho pansi pamavuto mukatembenuza chiwombankhangacho.

moni ngati ndikutsatirani bwino kuli bwino kuwomba mpweya woponderezedwa kudzera pa valve yothandizira kusiyana ndi phokoso la funnel
