Ts'ebetso le ts'ebeliso ea valve ea ho fokotsa khatello

Haeba ba bangata ba rona re tloaelane le valve ea liphallelo ea Wastegate turbo (bala ho eketsehileng mona), valve ea khatello ea khatello ho hlakile hore ha e tsejoe haholo ... Hobane'ng? Ho lokile, hobane rona Mafora re lemaletse diesel hoo re lebalang ka eona. Ha e le hantle, valve ena ea liphallelo e sebelisoa feela ha re e-na le 'mele oa throttle ho lumella throttle, joalokaha ho le joalo ka peterole (hammoho le di-diesel, ho sebelisa valve ea EGR, har'a lintho tse ling). Sheba phapang pakeng tsa peterole le diesel mona. Ho fapana le valve e tsejoang ea tšireletso, ea morao-rao e fumaneha ka lehlakoreng la ho kena.

Kahoo, haeba re hopola, re na le valve ea exhaust ka lehlakoreng la mouoane, ebang ke ka peterole kapa diesel, le e 'ngoe e kenang ha e le enjene ea peterole. Ka bobeli li na le molao-motheo o tšoanang, empa re ntse re tla li bitsa mabitso a fapaneng ho li khetholla: Wastegate bakeng sa mosi le Dump Valve bakeng sa ho noa. Kahoo, tseba hore Wastegate e u lumella ho eketsa matla a enjene (haeba re eketsa khatello ea ho kena moeeng), ha valve ea ho lahla e lekanyelitsoe feela ho sireletsa turbocharger.

Mokelikeli o sebelisetsoa ho potoloha turbocharger ho feta kapa ka tlase ka potlako (ka ho hapa likhase tse ngata kapa tse fokolang) 'me ka hona ho fana ka moea o mongata kapa o fokolang boema-kepeng ba ho kenya: ha chelete e ntse e eketseha, moea o kenang o ntse o eketseha. khatello (e petelitsoe ka koleke). Ka hona, likhase tsa ho qeta li potoloha turbine, empa haeba re ntša tse ling tsa likhase tsena ho li tlosa, joale turbine e tla tsamaea butle (hobane lekhetlong lena re sebelisa tse ling tsa ho tima, eseng kaofela). Ha enjene e kena sebakeng se bolokehileng, Wastegate e bulehile ka botlalo, ebe re na le enjene e batlang e le ka tlhaho mme ka hona re lahleheloa ke matla. Ba sa utloisiseng letho ba lokela ho sheba turbocharger ka lehlakoreng le leng: mona u ka bona setšoantšo sa ts'ebetso ea eona.

Ka lehlakoreng le leng, valve e teng ho kenngoa, e tsejoang ke Dump Valve, e etsa ntho e tšoanang empa ka lehlakoreng la ho kenya.
