Kukula kwaukadaulo wa turbocharging
Tekinoloje ya Turbocharging idaperekedwa koyamba ndi Posey, injiniya ku Switzerland, ndipo adafunsiranso patent ya "ukadaulo wowonjezera wa injini yoyaka moto".Cholinga choyambirira cha teknolojiyi chinali kugwiritsidwa ntchito mu ndege ndi akasinja mpaka 1961. , General Motors wa United States anayamba kuyesa kukhazikitsa turbocharger pa chitsanzo cha Chevrolet, koma chifukwa cha luso lochepa panthawiyo, panali zambiri. mavuto, ndipo sichinakwezedwe mofala.
M'zaka za m'ma 1970, Porsche 911 yokhala ndi injini ya turbocharged inatuluka, yomwe inasintha kwambiri chitukuko cha luso la turbocharging.Pambuyo pake, Saab adasintha ukadaulo wa turbocharging, kotero kuti ukadaulo uwu wagwiritsidwa ntchito kwambiri.
Mfundo ya turbocharging
Mfundo yaukadaulo wa turbocharging ndiyosavuta, yomwe ndikugwiritsa ntchito mpweya wotuluka mu injini kukankhira chopondera kuti mupange mphamvu, kuyendetsa makina opangira coaxial, ndikukakamiza mpweya kulowa mu silinda, potero kuwonjezera mphamvu ndi torque ya injini.
Ndi chitukuko cha teknoloji, pakhala pali turbine yamagetsi, yomwe imayendetsa mpweya wa compressor kupyolera mumoto.Onse a iwo ali ndi mfundo yofanana kwenikweni, onse ndi opondereza mpweya, koma mawonekedwe a supercharging ndi osiyana.
Ndi kutchuka kwaukadaulo wa turbocharging, anthu ena angaganize kuti ngati turbocharger yathyoka, zimangokhudza kuchuluka kwa mpweya wa injiniyo.Kodi angagwiritsidwe ntchito ngati injini mwachilengedwe?
Sangagwiritsidwe ntchito ngati injini yodzipangira yokha
Kuchokera pamakina owonera, zikuwoneka zotheka.Koma kwenikweni, turbocharger ikalephera, injini yonse idzakhudzidwa kwambiri.Chifukwa pali kusiyana kwakukulu pakati pa injini ya turbocharged ndi injini yolakalaka mwachilengedwe.
Mwachitsanzo, pofuna kuletsa kugogoda kwa injini za turbocharged, chiŵerengero cha kuponderezana chimakhala pakati pa 9: 1 ndi 10: 1.Pofuna kufinya mphamvu momwe mungathere, kuchuluka kwa ma injini omwe amafunidwa mwachilengedwe kuli pamwamba pa 11: 1, zomwe zimatsogolera ku Ma injini awiriwa amasiyana ndi ma valve, ma valve overlap angle, logic control engine, komanso mawonekedwe a pistoni.
Zili ngati munthu amene akudwala chimfine ndipo mphuno yake ilibe mpweya wabwino.Ngakhale kuti amatha kupuma, zimakhala zovuta kwambiri.Pamene turbocharger ali ndi zolephera zosiyana, zotsatira za injini zingakhalenso zazikulu kapena zazing'ono.
Zizindikiro za Kulephera kwa Turbine
Zizindikiro zoonekeratu ndizochepa mphamvu ya galimoto, kuwonjezeka kwa mafuta, kuyaka kwa mafuta, utsi wa buluu kapena utsi wakuda kuchokera ku chitoliro chotulutsa mpweya, phokoso losazolowereka kapena ngakhale phokoso lopweteka pamene mukufulumizitsa kapena kutseka accelerator.Chifukwa chake, turbocharger ikathyoka, siyenera kugwiritsidwa ntchito ngati injini yodzipangira yokha.
Mtundu Wolephera wa Turbine
Pali zifukwa zambiri zakulephera kwa turbocharger, zomwe zitha kugawidwa m'magulu atatu.
1. Pali vuto ndi ntchito yosindikiza, monga chisindikizo chosauka cha impeller shaft, mpweya wowonongeka, kuvala ndi kukalamba kwa chisindikizo cha mafuta, ndi zina zotero. koma izi zipangitsa kuti mafuta achuluke, kuwotcha mafuta, kuyendetsa galimoto kwa nthawi yayitali, komanso kuwonjezereka kwa mpweya, zomwe zimapangitsa injini kukokera silinda.
2. Mtundu wachiwiri wa vuto ndi blockage.Mwachitsanzo, ngati payipi ya mpweya wotulutsa mpweya watsekedwa, kulowetsedwa ndi kutulutsa kwa injini kudzakhudzidwa, ndipo mphamvu idzakhudzidwa kwambiri;
3. Mtundu wachitatu ndi kulephera kwa makina.Mwachitsanzo, choponderetsa chathyoka, payipi yawonongeka, ndi zina zotero, zomwe zingapangitse zinthu zina zakunja kulowa mu injini, ndipo mwinamwake injini idzachotsedwa mwachindunji.
Moyo wa Turbocharger
M'malo mwake, ukadaulo waposachedwa wa turbocharging ukhoza kutsimikizira moyo wautumiki womwewo ngati injini.Turbo imadaliranso kwambiri mafuta kuti azipaka mafuta ndikuchotsa kutentha.Choncho, kwa zitsanzo za turbocharged, malinga ngati mumvetsera kusankha ndi khalidwe la mafuta panthawi yokonza galimoto, makamaka zolephera zazikulu ndizosowa.
Ngati mukukumana ndi zowonongeka, mutha kupitiliza kuyendetsa pa liwiro lotsika pansi pa 1500 rpm, yesetsani kupewa kulowererapo kwa turbo, ndikupita ku malo ogulitsa akatswiri kuti mukonzenso posachedwa.
