Iyini i-intercooler yemoto
I-intercooler emotweni iyidivayisi esekelayo yokukhipha ukushisa yezinjini ezine-turbocharged, esetshenziselwa ukupholisa umoya wezinga lokushisa eliphezulu ngemva kokushaja i-turbo ukuze kuthuthukiswe ukusebenza kahle kwenjini nokusebenza kwamandla.
Incazelo eyisisekelo nomsebenzi
I-Intercooler, ingxenye eyinhloko yenjini eshajwe kakhulu njengenjini ene-turbocharged noma ene-supercharged, ifakwa phakathi kweshaja enkulu kanye nenani eliningi lokudla. Umsebenzi wawo oyinhloko ukwehlisa izinga lokushisa lomoya oshajwe kakhulu. Imisebenzi yayo eyinhloko ihlanganisa:
I-Youdaoplaceholder0 Ukupholisa komoya oshisayo : Ngesikhathi sokushajwa okukhulu, umoya uyacindezelwa, okubangele ukuthi izinga lokushisa lawo likhuphuke (kufika ku-200 ° C). I-intercooler inciphisa izinga lokushisa libe yibanga elifanele (imvamisa engu-50-60 ° C) ngokukhipha ukushisa, ukuvimbela ukulayisha ngokweqile okushisayo enjinini.
I-Youdaoplaceholder0 Thuthukisa ukusebenza kahle komlilo : Umoya onezinga lokushisa eliphansi unokuminyana okuphezulu, okwandisa umthamo owuthathayo futhi unike amandla ukusha kukaphethiloli okuphelele, ngaleyo ndlela kuthuthukise amandla (njalo ngo-10 ° C ukwehla kwezinga lokushisa lomoya ocindezelwe, amandla akhuphuka ngo-3% -5%).
I-Youdaoplaceholder0 Yehlisa ukuqhunyiswa nokukhishwa kwekhabhoni : Umoya othathayo onezinga lokushisa eliphezulu uthambekele ekubeni ubangele ukuwohloka, kuyilapho ukupholisa kunciphisa ukukhishwa kwe-NOx nokunye ukungcola.
Thayipha nokuthi isebenza kanjani
Ama-Intercoolers ahlukaniswe abe izindlela ezimbili zokupholisa ezijwayelekile:
I-Youdaoplaceholder0 I-Air-cooled : Isebenzisa ukugeleza komoya okukhiqizwa imoto phakathi nokunyakaza ukuze ikhiphe ukushisa. Ivamise ukufakwa ngaphambili emotweni noma eduze kwe-radiator. Inesakhiwo esilula kanye nezindleko eziphansi, kodwa ithinteka kakhulu izinga lokushisa elizungezile.
I-Youdaoplaceholder0 Ipholile ngamanzi : Iphola ngokujikeleza kwesipholile senjini, ihlinzeka ngezinga lokushisa elingcono elihlala njalo. Ilungele izimoto ezinesikhala (njengezinye ezisebenza kahle kakhulu), kodwa umphumela wokupholisa ngokuvamile ungaphansi kwalowo wokupholisa umoya.
Izinto zokwakha kanye nezakhiwo
I-Youdaoplaceholder0 Material : iningi lenziwe nge-aluminium alloy ngenxa yesisindo sayo esilula kanye ne-thermal conductivity enhle kakhulu.
I-Youdaoplaceholder0 Design : Ingaphakathi lakhiwe amashubhu aminyene namaphiko, adonsa futhi akhiphe ukushisa njengoba igesi igeleza kumashubhu.
Amanothi okugcina nokuguqulwa
Ukuhlanza i-Youdaoplaceholder0 : Hlanza njalo uthuli lwangaphandle (gwema ukufafaza nge-oblique ngesibhamu samanzi esinomfutho ophezulu) bese uhlola ngaphakathi ukuthi akukho yini ukuvaleka.
Iziphakamiso zokuguqulwa kwe-Youdaoplaceholder0 :
Khetha usayizi ofanele ukuze ulinganise ukusebenza kahle kokupholisa nokulahlekelwa kwengcindezi;
Ipayipi kufanele lifushaniswe ngangokunokwenzeka futhi ligcinwe liqondile ukuze kuncishiswe ukumelana nokugeleza komoya.
Ububanzi bepayipi lokuphumayo kudingeka bube ugqinsi ngo-10% kunepayipi elingenayo ukuze kuthuthukiswe izinga lokugeleza.
Izimo ezisebenzayo
Izinjini ezine-turbocharged kuphela ezidinga ukuhlonyiswa ngama-intercoolers, kuyilapho izinjini ezishisekela ngokwemvelo aziyidingi le divayisi ngenxa yezinga lokushisa eliphansi lomoya.
Yehlisa izinga lokushisa lomoya ocindezelwe ukwandisa amandla nokusebenza kahle kwenjini
Umsebenzi oyinhloko: Ukupholisa umoya ocindezelwe
I-intercooler iyisakhi esiyinhloko sezinjini ezine-turbocharged noma ezine-supercharged, etholakala phakathi kwe-turbocharger kanye nenani eliningi lokudla. Umsebenzi wayo oyinhloko ukupholisa umoya onezinga lokushisa eliphezulu ocindezelwe i-turbocharger (enezinga lokushisa elifinyelela ku-80-200℃), nokunciphisa izinga lokushisa lomoya owuthathayo ngokushintshanisa ukushisa, ngaleyo ndlela:
I-Youdaoplaceholder0 Khulisa ukuminyana komoya : Uma upholile, umthamo womoya uyancipha futhi okuqukethwe komoyampilo kuyakhuphuka, okwenza ngcono ukusebenza kahle kwamandla emali enjini.
I-Youdaoplaceholder0 Khulisa ukuphuma kwamandla : Ukuhlola kubonisa ukuthi njalo ngo-10 ° C ukwehla kwezinga lokushisa komoya onomfutho, amandla enjini akhuphuka ngo-3% ukuya ku-5%.
Lungiselela ukusebenza kwenjini nokuthembeka
I-Youdaoplaceholder0 Yehlisa umthwalo wokushisa : Umoya othathayo onezinga lokushisa eliphezulu uqinisa ingcindezi yokushisa egunjini lomlilo wenjini. I-intercooler ipholisa phansi ukuvimbela ukungqongqoza, ukuguqulwa kwekhanda le-cylinder nezinye izinkinga.
I-Youdaoplaceholder0 Ukukhishwa okuphansi : Umoya opholile ushisa ngokuphelele, wehlisa i-nitrogen oxide (NOx) kanye nokukhishwa kwentuthu emnyama.
I-Youdaoplaceholder0 Thuthukisa ukonga kukaphethiloli : Umoya obandayo uxubana ngokulinganayo nophethiloli, uthuthukisa ukusebenza kahle komlilo futhi unciphise ukusetshenziswa kukaphethiloli.
Ukuvumelana nezimo okukhethekile kwezemvelo
Ezindaweni eziphakeme, ama-intercoolers avumela ukusetshenziswa kwama-compressor anezinga eliphezulu lokucindezela ukuze kunxeshezelwe ukulahlekelwa amandla okubangelwa umoya-mpilo omncane futhi kuthuthukise ukuguquguquka kwamandla emoto.
Umehluko wohlobo nokuklama
I-Youdaoplaceholder0 I-Air-cooled (i-air-air cooler) : Ivamise ukusetshenziswa ezimotweni zabagibeli, ipholisa umoya ocindezelwe ngomoya ongaphandle. Inesakhiwo esilula kodwa ithintwa kakhulu izinga lokushisa elizungezile.
I-Youdaoplaceholder0 Ipholile ngamanzi : Ichitha ukushisa ngesinqamuleli, isebenza kahle kakhulu kodwa ibiza kakhulu, futhi isetshenziswa kakhulu kumamodeli asebenza kahle kakhulu.
I-Youdaoplaceholder0 Overhead intercooler (isb. I-Subaru Impreza) : yenza kube mfishane i-stroke oyithathayo kodwa inomphumela ophansi kancane wokuqeda ukushisa, futhi ingcono ekulinganiseni amandla nokusetshenziswa kukaphethiloli.
I-Youdaoplaceholder0 Umthelela wokwehluleka : Uma i-intercooler ivuza, izodala amandla ancishisiwe, ukusetshenziswa kukaphethiloli okwenyuka, ngisho nokuguga okusheshisiwe ngenxa yezinhlayiya zesihlabathi ezingena kusilinda.
Uma ukuthuthukiswa okwengeziwe komklamo kudingeka, ukunakwa kufanele kukhokhwe kumazinga wezinto ezibonakalayo (afana ne-GB 3880 yamapuleti e-aluminium alloy) kanye nezidingo zenqubo yangaphezulu.
