Iyini i-EGR cooler?

uhlelo lwenjinifuthi kanjani konke umsebenzi onzima
Izingxenye, it kufanele
ukusebenza ezimweni ezinzima kakhulu.
Kodwa kungani ukhipha amagesi
isebenza ngalolu hlelo idinga ukupholiswa? Kanjani
Uyazi ukuthi isipholile enjinini yakho siyehluleka?

idinga ukuhlanzwa? Ungakwazi
vimbela i-EGR yakho
okupholile
ekuhlulekeni? Qhubeka ufunda ukuze uthole izimpendulo zale mibuzo neminye.
qinisekisa ubude bokuphila be-EGR cooler yakho
futhi uvikele injini yakho.
Yenzani i-EGR cooler?
ukungcola
buya ifomu kunokungashiswa nje amagesi
kusuka enjinini yakho. Bona
kwakheka futhi lapho kunokushisa okukhulu ngaphakathi kwakho ukusha kukadizili
i-chamber iphula izibopho zamakhemikhali, yenze ama-molecule amasha. I-nitrogen oxides (NOx) kanye
i-ozone (O3) yakheka lapho lokhu kushisa kuhlanganisa ama-athomu e-nitrogen ne-oxygen
umoya. I-NOx ingakheka
intuthu, futhi uma ixubene namanzi ingenza imvula ene-asidi. I-ozone layer iyasivikela
ukukhanya kwe-ultraviolet, kodwa ezingeni eliphansi le gesi ingabangela izinkinga zokuphefumula,
ikakhulukazi kulabo abanamaphaphu azwelayo/izinkinga zokuphefumula.
Qeda
I-Gas recirculation (EGR) yehlisa izinga lokushisa lomlilo ngokuhlambulula ingxube yomoya/yamafutha.
ingxube nenani elincane lamagesi aphumayo angasebenzi.Firm
ukusebenza kwakho injini I-REMAins высокая, kuyilapho kungenzeka ukungcola
ukwakheka kuncishiswe kakhulu. I-air dilution esebenza kahle kakhulu
/ igesi ingxube kuyintos
lapho ifasitela
amagesi e-exhaust ayabanda, yingakho ukuba khona kwe-EGR cooler.
I-EGR
okupholile - kuyinto amanzi emoyeni
isishintshi sokushisa, okuyinto ihlala phakathi kwe-turbo ne-EGR valve.
Umzimba unayo
ishubhu elingenalutho noma uchungechunge lwamashubhu okudlula kuwo amagesi akhipha umoya oshisayo.
Lawa mapayipi azungezwe amaphaseji amaningana apholile. Ukushisa is
dlulisiwe ezindongeni ezihlukanayo
i-exhaust kanye ne-coolant, ehlinzeka ngamagesi apholile, angenayo i-exhaust alungele ukusebenza
amazinga okushisa omlilo aphansi. I-exhaust gas igeleza nge-EGR
Isipholile silawulwa ikhompuyutha esebhodini ngevalvu ye-EGR.
Firm ukushisa okuvela ohlelweni lwe-exhaust
idluliselwe ohlelweni lokupholisa imoto. Le mfudumalo eyengeziwe ilungile
ahlakazeke nge-radiator. Kodwa-ke, njengoba i-EGR epholile ixhuma
amasistimu okukhipha amandla kanye nokupholisa enjini yakho, ukungasebenzi kahle kwe-cooler kungaholela
ukulahlekelwa kokupholisa, ukushisa ngokweqile kanye nokulimala kwenjini, phakathi kokunye ukwehluleka.
Kwenzekani uma i-EGR cooler yakho ihluleka?
Uma i-EGR cooler ihluleka,
kubi. Ngokuvamile,
kuzoba nokuqhekeka noma ukuvuza phakathi kwesipholisa kanye nohlangothi lwe-exhaust
okupholile. Lokhu ngokuvamile kuzosho ukuthi isipholile singena epayipini le-exhaust.
indlela yegesi lapho ibuyela enjinini. Ngomqondo othile lokhu
is
uthele amanzi enjinini. Uphawu lokuqala olujwayelekile
of
intuthu emhlophe evela epayipini lokukhipha umoya lapho isipholile siphenduka umhwamuko
kusuka epayipini lokukhipha umoya. Ungase futhi uqaphele
izinga lokupholisa eliphansi eliphindaphindayo noma isipholile
zichichima njengoba isipholile sidonselwa ku
indlela yokukhipha i-exhaust noma amagesi aphumayo angena endleleni epholile.
Kusukela ngodizili
ingumshini wevolumu ongashintshi, isitimu esijovwe sizoba
ucingo
ukuze isixhumanisi esibuthakathaka enjinini yakho ethile singasebenzi.Catastanzaic
umonakalo omkhulu wenjini ungenzeka ngenxa yokubiliswa kwesipholile.
ikamelo lomlilo, icindezela kakhulu ingaphakathi
izingxenye zenjini.
kungani
Ingabe ama-coolers e-AMBAC EGR angcono?
Njengoba sineminyaka engu-110 yomlando embonini, siwubonile umbukiso wethu
ingxenye yamaphutha omklamo. KANYE ngokuvamile, qeda amasistimu okubuyisela kabusha igesi
ama-coolers awahlukile. TIdizayini ye-OEM inephutha;
impahla incane kakhulu futhi izimbobo zincane kakhulu(Kanjani
isigaba se-radiator). Lapho zigcwala umule (exhaust fumes
dlula kuyo), ziyashisa. Kuyabangela isiliva solder в
ncibilika
cooler ukuhlukana,
ukuvumela into epholile ukuthi ihlangane namagesi aphumayo, Kungenzeka
dala izinkinga iqala ngokuhluleka kwe-turbine, egcina ngokuqhunyiswa
ama-cylinder head gaskets namabhawodi ekhanda lesilinda aphukile в
izinduku zokuxhuma namapiston.
Ama-coolers ethu e-EGR alwa nale nkinga,
iklanywe kabusha ngobubanzi obukhulu,
amapayipi odongeni awugqinsi enziwa
kusuka ku-303
insimbi engagqwali. Bese behlanganiswa ndawonye hhayi ngesiliva
soldered, ukuqinisekisa ukuthi cooler ngeke
ukuhlukana.
