Chii chinonzi double scroll turbocharger? [hutungamiri]

Magadzirirwo emasupercharger masisitimu anosiyana zvichienderana nezvinodiwa nevagadziri. Chimwe chezvido zvisina kujairika chishuwo chekuwana yakakwira torque pane yakaderera inokwanisika kumhanya, usiri kukanda mapfumo pasi pane ichiri yakakwira kukosha nekumhanya kwakanyanya, uye iyi iri muinjini yepeturu. Zvinoita sekuti injini ye peturu haizombovi negomba rakasimba senge injini yedhiziri, asi zvinoitika kuti inogona. Izvo zvese nekuda kweiyo kaviri scroll system.

Iwe unogona kushandisa nzira dzakasiyana dzekuzadza, kusanganisira. chinja geometry kana mapatya-turbo uye bi-turbo masisitimu, asi mune yega yega pane dambudziko iro kupera gasi kubva kumasilinda ega haapindi mu turbine rotor panguva imwe chete uye zvakaenzana, asi nenzira inorovesa nehana. Nekuda kweizvozvo, vanopindirana mumwe nemumwe pamusuwo weimba ye turbine uye havashandisi kugona kwavo kuzere.

Saka twin-scroll turbocharged solution inotsemura manifold exhaust kuita machaneli maviri (inoratidzwa mutsvuku), imwe yayo inoshumira, semuenzaniso, mune injini ye-4-cylinder, mavhavha ekunze, uye imwe yacho, mavhiri emukati. Izvi zvinodzivirira kukanganiswa nekuyerera kwese kuenda kune turbine imba. Kunewo nzira mbiri pano, asi pane imwe kamuri pamberi pe rotor (inoratidzwa mubhuruu). Nekusarudza hurefu hwakakodzera uye huwandu hwezviteshi zvekutora, unogona kushandisa wave phenomena inosanganiswa neiyo pulsating kutenderera kweinjini, uye zvakanyanya kushandisa simba remagasi ekupedza. Nekuda kwekupatsanurwa uku mudzimba dzeturbine, kuvhiringika kusingakodzeri kusikwa nekumhanya kwakaderera, uye diki turbocharger inopindura nekukurumidza kudzvanya gasi pedal.

Mumagadzirirwo akadai, hapana chikonzero chekuchinja turbine geometry.iyo isinganyanyi kushandiswa mumainjini epeturu. Uye zvakadaro chinhu chikuru cheiyo twin-scroll turbocharged injini ndeye kukurumidza kuita kwekuwedzera kwegasi. Zvinogona kutotaurwa pachena kuti iyi mhando ye turbocharger inobvisa zvakanyanya chiitiko che turbolag.

Imwe yemapiyona mukushandiswa kweiyo twin-scroll turbo system iBMW. iyo inoshandisa izwi rekuti Twin Power Turbo kumayuniti ayo. Zvakakosha kucherechedza pano kuti hapana chinodzivirira kushandiswa kwematwin-scroll turbochargers mumapatya-musoro injini dzakadai seV8s. Mumwe muenzaniso ndeye Ford, iyo yakashandisa twin-scroll turbocharger pasporty Focus RS. Avo vakatyaira mota iyi vanoziva kuti injini yayo inokurumidza kuita sei pakuwedzera kwegasi uye kuti ine simba rakadii mune yega rev rev. Zvakwana kutaura kuti iyi 2,3-litre peturu unit inogadzira 440 Nm kubva pa2000 kusvika 4500 rpm. Imwe kambani yakashandisa twin-scroll turbocharger iLexus. MuNX, iine 2-litre peturu injini.
