Kuyini i-intercooler
I-intercooler iyithuluzi lokususa ukushisa elisetshenziselwa ukwehlisa izinga lokushisa lomoya ongenayo injini. Isetshenziswa kakhulu ezinjinini ezine-turbocharger noma ezine-supercharger, okuthuthukisa ukusebenza kahle kwenjini kanye nokuqina ngokupholisa umoya oshisa kakhulu ngemva kokushaja kakhulu.
Umsebenzi oyinhloko we-intercooler ngu-
I-Intercooler iyisici esibalulekile ohlelweni lwenjini olune-turbocharger. Umsebenzi wayo oyinhloko ukwehlisa izinga lokushisa lomoya oshisa kakhulu ngemva kwe-turbocharger ngokusebenzisa isimiso sokushintshana kokushisa. Ngesikhathi senqubo ye-turbocharging noma i-mechanical supercharging, ukucindezelwa komoya kungabangela ukwanda okukhulu kwezinga lokushisa (kufika ku-200℃). Uma ingena ngqo ekamelweni lokushisa, izobangela ukungqongqoza, inciphise ukusebenza kahle kokushaja futhi inyuse ukukhishwa kokungcola. I-intercooler inganciphisa izinga lokushisa lomoya ongenayo ngama-degree Celsius angu-50 kuya kwangu-60, inyuse ubuningi bomoya, ngaleyo ndlela ithuthukise amandla enjini ngo-3% kuya ku-5%.
Isimiso sokusebenza se-Youdaoplaceholder0 kanye nohlobo
Isimiso sokusebenza se-Youdaoplaceholder0 .
I-intercooler ishintshana ngokushisa nomoya ocindezelwe okushisa okuphezulu ngokusebenzisa indawo yokupholisa (umoya noma uketshezi). Umoya ocindezelwe ugeleza ngamapayipi okusabalalisa ukushisa e-intercooler, lapho ukushisa kuthuthwa khona umoya wangaphandle noma i-coolant. Umoya opholile ube usungena ekamelweni lokushisa injini.
Uhlobo olupholiswe ngomoya: Lusebenzisa ukugeleza komoya okuzayo noma ukupholisa ifeni lapho imoto inyakaza. Lunesakhiwo esilula kodwa ukusebenza kahle okuphansi ngesivinini esiphansi.
Uhlobo olupholiswe ngamanzi: Lukhipha ukushisa ngokujikeleza kwe-coolant yenjini. Umphumela wokupholisa uzinzile kodwa isakhiwo siyinkimbinkimbi.
Izinto zokwakha kanye nomklamo we-Youdaoplaceholder0.
Ngokuvamile yenziwe nge-aluminium alloy ngenxa yokushisa kwayo okuhle kakhulu. Umklamo udinga ukulinganisela ukusebenza kahle kokupholisa kanye nokumelana nokugeleza komoya. I-intercooler enkulu kakhulu ingandisa i-turbine hysteresis.
Inani lesicelo esisebenzayo se-Youdaoplaceholder0
Ukuthuthukiswa kokusebenza kwe-Youdaoplaceholder0: Ukwehlisa izinga lokushisa lomoya ongeniswayo kungathuthukisa ukusebenza kahle kokwehla kwamandla emali, kwandise ukukhishwa kwamandla futhi kunciphise ukusetshenziswa kukaphethiloli.
I-Youdaoplaceholder0 Vikela injini : gwema ukungqongqoza kanye nomonakalo wemishini obangelwa amazinga okushisa aphezulu, futhi wandise isikhathi sokuphila kwenjini.
Izinzuzo ze-Youdaoplaceholder0 zemvelo : Kunciphisa ukukhishwa kwe-nitrogen oxide (NOx), kuhlangabezana nezidingo zokuvikelwa kwemvelo.
Umsebenzi oyinhloko we-intercooler ukwehlisa izinga lokushisa lomoya ongenayo injini ene-turbocharger, ukwandisa ubuningi bomoya ongenayo, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokushisa kanye nokukhishwa kwamandla, ngenkathi kuvinjelwa ukukhiya nokunciphisa ukukhishwa kokungcola.
Umsebenzi oyinhloko kanye nendlela yokusebenza kwe-intercooler
I-Youdaoplaceholder0 ipholisa umoya ocindezelwe .
Ngesikhathi senqubo yokushaja nge-turbo, izinga lokushisa lomoya ocindezelwe likhuphuka kakhulu (ngokuvamile lifinyelela ngaphezu kuka-120℃), okuholela ekwehleni kobuningi be-oxygen. I-intercooler yehlisa izinga lokushisa lomoya ongenayo libe ngu-50-60℃ ngokushabalalisa ukushisa, okwandisa ubuningi bomoya cishe ngo-30%.
Idatha yokuhlola ikhombisa ukuthi ngokwehla ngakunye kokushisa komoya okungenayo okungu-10℃, amandla enjini angakhuphuka ngo-3% kuya ku-5%.
I-Youdaoplaceholder0 ithuthukisa ukusebenza kahle kokushisa .
Umoya ophansi kanye nowokuxinana okuphezulu kwenza kube lula ukwenza uphethiloli ube yi-atomization ephelele, ukulawula okunembile kwesilinganiso somoya nophethiloli, kanye nokushisa okuphelele. Lokhu akugcini nje ngokuthuthukisa ukukhishwa kwamandla kodwa futhi kunciphisa ukusetshenziswa kukaphethiloli cishe ngo-5% kuya ku-10%.
I-Youdaoplaceholder0 ivimbela izimo zokusebenza ezingajwayelekile zenjini.
Susa izinto ezibangela ukushisa nokushaya okubangelwa amagesi ashisa kakhulu ukuze uvimbele ukuguguleka nokudabuka okungavamile kwezingxenye ezibalulekile njenge-piston nama-valve.
Nciphisa ukukhishwa kwe-nitrogen oxide (NOx) ngo-20% kuya ku-30% ukuze kuhlangatshezwane nezindinganiso eziqinile zokuvikela imvelo.
I-Youdaoplaceholder0 Ukuzivumelanisa nezimo okukhethekile kwemvelo
Isinxephezelo se-Youdaoplaceholder0 sokuphakama okuphezulu .
Ezindaweni ezingaphezu kwamamitha angu-3,000 ukuphakama, i-intercooler ingagcina cishe u-85% wokusebenza kahle kohlelo lokucindezela ngaphansi kwezimo ezicacile, futhi ukwehla kokusebenza kohlelo lokucindezela ngaphandle kwe-intercooler kuncishiswa ngo-40%.
Ukwenziwa ngcono kokubambisana kwesistimu ye-Youdaoplaceholder0 .
Amapharamitha okungenisa azinzile ngemva kokupholisa avumela i-turbocharger ukuthi ifane nesilinganiso sokucindezela esiphezulu (ngokuvamile sikhuphuke ngo-15% kuya ku-20%), okufeza ukuhlanganiswa okuhle kakhulu phakathi kohlelo lwe-turbocharging nenjini.
