Yintoni i-intercooler yemoto
I-intercooler emotweni sisixhobo esixhasayo sokulahla ubushushu kwiinjini ze-turbocharged, ezisetyenziselwa ukupholisa umoya wobushushu obuphezulu emva kwe-turbocharging ukunyusa ukusebenza kwe-injini kunye nokusebenza kwamandla.
Inkcazo esisiseko kunye nomsebenzi
I-Intercooler, icandelo eliphambili le-injini etshajiwe kakhulu efana ne-turbocharged okanye i-injini ephezulu, ifakwe phakathi kwe-supercharger kunye ne-intake manifold. Owona msebenzi wayo kukuthoba ubushushu bomoya otshajiweyo. Imisebenzi yayo ephambili ibandakanya:
I-Youdaoplaceholder0 Ukupholisa umoya oshushu : Ngexesha lokutshaja kakhulu, umoya uyacinezelwa, ubangele ukuba ubushushu bawo bunyuke (ukuya kuma-200 ° C). I-intercooler inciphisa ubushushu ukuya kuluhlu olufanelekileyo (ngokuqhelekileyo i-50-60 ° C) ngokuchithwa kobushushu, ukuthintela umthwalo oshushu ogqithiseleyo kwi-injini.
I-Youdaoplaceholder0
Youdaoplaceholder0 Nciphisa ukuqhawuka kunye nokukhutshwayo : Ubushushu obuphezulu bomoya buthanda ukubangela ukuthotywa, ngelixa ukupholisa kunciphisa ukukhutshwa kwe-NOx kunye nezinye izinto ezingcolisayo.
Chwetheza kunye INDLELA esebenza ngayo
Ii-Intercoolers zahlulwe zaba ziindlela ezimbini zokupholisa eziphambili:
I-Youdaoplaceholder0 I-Air-cooled : Isebenzisa ukuhamba komoya okwenziwa sisithuthi ngexesha lentshukumo ukukhupha ubushushu. Idla ngokufakwa ngaphambili kwisithuthi okanye kufuphi neradiyetha. Inesakhiwo esilula kunye neendleko eziphantsi, kodwa ichaphazeleka kakhulu ngubushushu be-ambient.
I-Youdaoplaceholder0 Ukupholisa ngamanzi : Iphola ngokujikeleziswa kwe-injini yokupholisa, ibonelela ngeqondo lobushushu elingcono. Ifanelekile kwizithuthi eziphantsi kwendawo (ezifana nezinye eziphezulu zokusebenza), kodwa umphumo wokupholisa udla ngokuba ngaphantsi kwe-air-cooled.
Izixhobo kunye noLwakhiwo
I-Youdaoplaceholder0 Material : ubukhulu becala yenziwe nge-aluminium alloy ngenxa yobunzima bayo obulula kunye ne-thermal conductivity egqwesileyo.
Uyilo lwe-Youdaoplaceholder0 : Ngaphakathi yenziwe ngeetyhubhu ezishinyeneyo kunye namaphiko, afunxa kwaye akhuphe ubushushu njengoko irhasi iqukuqela kwiityhubhu.
Amanqaku olondolozo kunye nohlengahlengiso
Ukucoca i-Youdaoplaceholder0 : Rhoqo uhlambulule uthuli lwangaphandle (kuphephe ukutshiza nge-oblique ngompu wamanzi woxinzelelo oluphezulu) kwaye ujonge ngaphakathi ukuvaleka.
Iingcebiso zoLungiso lwe-Youdaoplaceholder0 :
Khetha ubungakanani obufanelekileyo ukulinganisa ukusebenza kakuhle kokupholisa kunye nokulahlekelwa koxinzelelo;
Umbhobho kufuneka ucuthwe kangangoko kwaye ugcinwe uthe tye ukunciphisa ukuxhathisa kokuhamba komoya.
Idayamitha yombhobho wokuphuma kufuneka ibe malunga ne-10% ubukhulu kunombhobho wokungena ukuze kunyuswe umyinge wokuhamba.
Iimeko ezisebenzayo
Kuphela ii-injini ze-turbocharged kufuneka zixhotyiswe nge-intercoolers, ngelixa ii-injini ezinqwenelekayo ngokwendalo azifuni esi sixhobo ngenxa yobushushu bomoya obusezantsi.
Ukunciphisa ubushushu bomoya ocinezelekileyo ukwandisa amandla kunye nokusebenza kakuhle kwe-injini
Umsebenzi ongundoqo: Ukupholisa umoya ocinezelekileyo
I-intercooler yinxalenye ephambili yeenjini ze-turbocharged okanye i-supercharged, ephakathi kwe-turbocharger kunye ne-intake manifold. Umsebenzi wayo ophambili kukupholisa umoya wobushushu obuphezulu oxinaniswe yi-turbocharger (eneqondo lobushushu ukuya kuthi ga kwi-80-200℃), kunye nokunciphisa ubushushu bomoya othathayo ngokutshintshiselana kobushushu, ngaloo ndlela:
Youdaoplaceholder0 Yandisa ingxinano yomoya : Xa ipholile, umthamo womoya uyacutheka kwaye umxholo weoksijini uyenyuka, kuphucula ukusebenza kakuhle kokunyuka kwamaxabiso enjini.
Youdaoplaceholder0 Yandisa amandla emveliso : Iimvavanyo zibonisa ukuba rhoqo nge-10 ° C yehla kubushushu bomoya ocinezelekileyo, amandla e-injini anyuka nge-3% ukuya kwi-5%.
Yandisa ukusebenza kwe-injini kunye nokuthembeka
I-Youdaoplaceholder0 Yehlisa umthwalo wobushushu : Ubushushu obuphezulu bomoya bonyusa uxinzelelo lwe-thermal kwigumbi lokutsha le-injini. I-intercooler ipholisa phantsi ukukhusela ukunkqonkqoza, ukuguqulwa kwentloko ye-cylinder kunye nezinye iingxaki.
I-Youdaoplaceholder0 Ukukhutshwa okusezantsi : Umoya opholileyo utshisa ngokupheleleyo, wehlisa initrogen oxide (NOx) kunye nokukhutshwa komsi omnyama.
I-Youdaoplaceholder0 Phucula uqoqosho lwepetroli : Umoya obandayo uxuba ngokulinganayo namafutha, uphucula ukusebenza kakuhle kokutsha kwaye ucuthe ukusetyenziswa kwamafutha.
Ukuziqhelanisa okukhethekileyo kokusingqongileyo
Kwiindawo eziphakamileyo, ii-intercoolers zivumela ukusetyenziswa kwee-compressors ezinomlinganiselo ophezulu woxinzelelo ukubuyisela ukulahlekelwa kwamandla okubangelwa yi-oksijeni encinci kunye nokuphucula ukuguquguquka kwamandla esithuthi.
Uhlobo kunye nolwahlulo loyilo
I-Youdaoplaceholder0 I-Air-cooled (i-air-cooler) : Idla ngokusetyenziswa kwiimoto zabakhweli, ipholisa umoya ocinezelekileyo ngomoya wangaphandle. Inesakhiwo esilula kodwa ichatshazelwa kakhulu bubushushu be-ambient.
I-Youdaoplaceholder0 Ukupholiswa ngamanzi : Ikhupha ubushushu ngesipholisi, isebenza kakuhle kodwa ibiza kakhulu, kwaye isetyenziswa kakhulu kwiimodeli ezisebenza kakhulu.
I-Youdaoplaceholder0 Overhead intercooler (umzekelo, i-Subaru Impreza) : yenza mfutshane i-stroke ethathayo kodwa inobunewunewu obusezantsi bokulahla ubushushu, kwaye ingcono ekulinganiseni amandla kunye nokusetyenziswa kwamafutha.
Impembelelo yokusilela kwe-Youdaoplaceholder0 : Ukuba i-intercooler iyavuza, iya kubangela ukucuthwa kwamandla, ukwanda kokusetyenziswa kwepetroli, kunye nokuguga okukhawulezileyo ngenxa yamasuntswana esanti angena kwi-cylinder.
Ukuba ukulungelelaniswa ngakumbi koyilo kuyadingeka, ingqwalasela kufuneka ihlawulwe kwimigangatho yezinto eziphathekayo (ezifana ne-GB 3880 yeeplate ze-aluminium alloy) kunye neemfuno zenkqubo yomhlaba.
