Yintoni ukusetyenziswa kwe-turbocharger liner yemoto
Indima ephambili ye-automotive turbocharger kukunyusa umthamo we-injini, ngaloo ndlela ukwandisa amandla okuvelisa kunye ne-torque ye-injini, ukuze isithuthi sifumane amandla amaninzi. Ngokukodwa, i-turbocharger isebenzisa amandla erhasi ephuma kwi-injini ukuqhuba icompressor, kwaye inxinzelela umoya kumbhobho wokuthatha, inyusa ingxinano yokuthatha, ivumela i-injini ukuba itshise amafutha amaninzi, ngaloo ndlela inyusa ukuphuma kwamandla.
Isebenza njani i-turbocharger
I-Turbocharger yenziwe ikakhulu ngamacandelo amabini: i-turbine kunye ne-compressor. Xa i-injini isebenza, igesi ephumayo iyakhutshwa ngombhobho wokuphuma, ityhala i-injini yomoya ukuba ijikeleze. Ukujikeleza kwe-injini yomoya kuqhuba i-compressor kwaye icinezele umoya kumbhobho wokuthatha, ngaloo ndlela kwandisa uxinzelelo lokungena kunye nokuphucula ukusebenza kakuhle kokutsha kunye nokuphuma kwamandla.
Izinto eziluncedo kunye nokungalunganga kwe-turbocharger
Izinto eziluncedo :
Ukonyuka kokukhutshwa kwamandla : I-Turbocharger iyakwazi ukunyusa ukungena komoya, ivumela injini ukuba ivelise amandla amaninzi kunye ne-torque yokufuduswa okufanayo.
Ukuphucula uqoqosho lwamafutha : Iinjini ezine-turbocharged zitshisa ngcono, zidla ngokugcina i-3% -5% yepetroli, kwaye zithembeke kakhulu, iimpawu ezifanelekileyo ezihambelanayo kunye nokuphendula okwethutyana.
ukuziqhelanisa nokuphakama okuphezulu: i-turbocharger inokwenza i-injini igcine amandla aphuma aphezulu kwindawo ephezulu, ukusombulula ingxaki yeoksijini encinci kwindawo ephezulu.
Izinto ezingalunganga :
I-Turbine hysteresis : ngenxa ye-inertia ye-injini ye-turbine kunye nokuthwala okuphakathi, xa i-exhaust gas inyuka ngokukhawuleza, isantya se-turbine asiyi kunyuka ngokukhawuleza, okukhokelela ekuphumeni kwamandla e-hysteresis.
Isiphumo sesantya esisezantsi asilunganga: kwimeko yesantya esisezantsi okanye i-traffic jam, isiphumo se-turbocharger ayicacanga, nokuba ngcono kunenjini enqwenelekayo ngokwendalo.
Ii-turbocharger zeemoto zenziwe ngezinto ezahlukeneyo ezinje ngamavili, iibheringi, amaqokobhe kunye nee-impellers. Amavili ahlala enziwe ngezinto ze-superalloy, ezifana ne-Inconel, i-Waspaloy, njl., ukuhlangabezana neemfuno zokushisa okuphezulu kunye noxinzelelo.
Iibheringi zihlala zenziwe nge-cermet kunye nezinye izinto zokuphucula ukunxiba kunye nokumelana nokubola.
Kwinxalenye yeqokobhe, iqokobhe lecompressor ubukhulu becala yi-aluminium alloy okanye i-magnesium alloy ukunciphisa ubunzima kunye nokuphucula ukusebenza kakuhle, ngelixa iqokobhe le-turbine ubukhulu becala iyintsimbi.
I-impeller kunye ne-shaft ubukhulu becala zenziwe ngentsimbi, ngakumbi i-compressor impeller ihlala isebenzisa i-superalloy, enokumelana nobushushu obuphezulu be-oxidation, amandla kunye nokumelana nokubola.
Izinto eziphathekayo zamalungu ahlukeneyo kunye nemisebenzi yazo
I-wheel hub : Ukusetyenziswa kwezixhobo ze-alloy ezinobushushu obuphezulu, njenge-Inconel, i-Waspaloy, njl., ukuhlangabezana neemfuno zokushisa okuphezulu kunye noxinzelelo.
ukuthwala : ihlala isetyenziselwa i-ceramic yentsimbi kunye nezinye izinto ukuphucula ukunxiba kunye nokumelana nomhlwa.
iqokobhe :
Iqokobhe lecompressor: ubukhulu becala i-aluminium alloy okanye i-magnesium alloy, ukunciphisa ubunzima kunye nokuphucula ukusebenza kakuhle.
Iqokobhe le turbine: ubukhulu becala imathiriyeli yentsimbi.
ii-impellers and shafts : ubukhulu becala intsimbi, ngakumbi ii-compressor impellers zihlala zisebenzisa i-superalloy, le ngxubevange inokumelana nobushushu obuphezulu be-oxidation, amandla kunye nokumelana nomhlwa.
Imiba enempembelelo yokukhethwa kwezinto eziphathekayo
Ukhetho lwemathiriyeli ye-turbocharger ikakhulu luqwalasela le miba ilandelayo:
Ubushushu obuphezulu kunye noxinzelelo oluphezulu: ubushushu bangaphakathi kunye noxinzelelo lwe-turbocharger luphezulu, kwaye kuyafuneka ukuba ukhethe izinto ezinobushushu obuphezulu kunye nokumelana noxinzelelo oluphezulu.
Ukumelana nokunxiba : iindawo ezinoxinzelelo kufuneka zibe nokuxhathisa okuthile ukuphucula ubomi benkonzo.
Iimpawu zoomatshini : imathiriyeli kufuneka ibe namandla okwaneleyo kunye nokuqina ukuze ihlangabezane neemfuno zokusebenza ngesantya esiphezulu.
