I-EGR imele igesi ephumayoukujikeleza kwakhona, ingcamango yokulawula ukukhutshwa kwesithuthi esetyenziswa kuzo zombini iinjini zepetroli kunye ne-diesel.Ivalve ye-EGR,esebenza ngokwahlukileyo ngokuxhomekeke kwindlela indala ngayo imoto nokuba isebenzisa ipetroli okanye idizili, yinxalenye ephambili kwimotoinkqubo yokukhupha kunye nempilo ye-injini.
IiPros and Cons of EGR Blocking okanye Cima:
I-EGR sisixhobo sokulawula ukukhutshwa kwezinto eziphuhliswe ngabavelisi beemoto, ezisebenza ukuqondisa kwakhona inxalenye yerhasi yokukhupha kwi-injini ethathayo.Njengoko umsebenzi we-EGR ikukunciphisa ukusebenza kakuhle kwe-injini kwimigangatho yokukhupha, ikwathoba ubomi be-injini.Ngoko ke yinto eqhelekileyo ukuvala ivalve ye-EGR ukuphucula umgangatho wesithuthi.
Okokuqala makhe sithethe ngeePros of blocking EGR valve:
Ukuvala i-EGR kuya kubuyisela ukusebenza kwe-injini kwincopho yayo ekhoyo.Oku kuthetha ukuba amafutha amancinci afunekayo ukugcina amandla afanayo akhoyo kwi-injini.
Njengoko ukusebenza kwe-injini kuguqulwa kube ngcono ngokuvala igesi ye-carbon dioxide iphinda ingene e-injini, ifumana amandla angcono kwiipiston kwii-RPM ezisezantsi.RPM imele revolutions ngomzuzu, kwayeis isetyenziswe njengomlinganiselo wokuba nawuphi na umatshini osebenza ngokukhawuleza kangakanani na ngexesha elinikiweyo.Ezimotweni,RPMilinganisa ukuba mangaphi amaxesha i-crankshaft ye-injini yenza ujikelezo olupheleleyo olupheleleyo ngomzuzu ngamnye, kwaye kunye nayo, mangaphi amaxesha ipiston nganye ihla isinyuka kumbhobho wayo.Akunyanzelekanga ukuba usebenze kwiigiya kakhulu ukuze udlule kwaye uqhubele phambili kwiitrafikhi zedolophu.
Njengoko i-EGR ivaliwe, umsizi wekhabhoni kunye namasuntswana aphuma ekungeneni kwakhona enjini.Oku kwenza ukuba i-injini ibe mininzi, ipistons kunye namanye amacandelo acoceke.I-injini ecocekileyo isebenza ngcono kwaye ifumana ubomi bokusebenza ngakumbi xa ithelekiswa naleyo inamasuntswana ekhabhoni ajikelezayo enjinini.
Isoot yekhabhoni isebenza njengesixhobo sokurhawuzelela kwaye inyusa ukunxiba kunye nokukrazula kumalungu ashukumayo.Xa iibhloko ze-EGR, i-injini ifumana ukusebenza kwincopho yayo yokusebenza kakuhle, oku kwenza ukuvutha okufanelekileyo kwi-cylinder nganye kwaye kutshise amafutha ngokufanelekileyo.
Njengoko isibaso sivutha ngokufanelekileyo, akusayi kubakho mafutha angatshiyo aphuncuke enjinini.Oku kwehlisa imveliso yomsi ophuma enjinini.Njengoko umoya ococekileyo ngakumbi utsalwa yi-injini, ukubamba kancinci kwi-accelerator pedal kuya kunika amandla awoneleyo okuhlangabezana neemfuno zakho.Oku kubeka uncumo ebusweni bakho kwaye kwenza kube lula ukuqhuba edolophini ukodlula ezinye iimoto.
Ukuvala i-EGR kuya kunciphisa ukuveliswa kwe-carbon soot njengoko itshisa amafutha ngokufanelekileyo kunye ne-oksijini eninzi yomoya.Oku kuthintela iibhloko zokuqala kwi-DPF kunye ne-catalytic converter.
Ngoku makhe sibone ii-Cons zokucima i-EGR:
Njengoko injongo ye-EGR kukunciphisa ukukhutshwa kwemoto emotweni, njengoko ivaliwe ingabona i-carbon soot encinci kodwa inyusa imveliso ye-NOx, i-Carbon monoxide, kunye nokunye okuyingozi kwindalo.
Ukuvala i-EGR kuya kwandisa ukusebenza kakuhle kwe-injini.Oku kuthetha, ukutshisa amafutha ngokufanelekileyo.Njengokutsha okufanelekileyo kunye namandla kunokunyusa kancinane isandi se-injini kunye nokungcangcazela.Njengoko i-EGR ivaliwe, ubushushu bokutsha buyanda.Oku kunyuka kobushushu obutshisayo kunokwenza ingxolo yokunkqonkqoza.
Ichaphazela iThuthi eTshwalwayo ye-Turbo:
Xa i-EGR ivaliwe, igesi ephumayo eninzi enobushushu obuphezulu kufuneka idlule kwitshaja ye-turbo, iyenze isebenze nzima kwaye inciphise ubomi bayo bube bufutshane.
Ukuvala i-EGR kuphucula ukusebenza kwe-injini, oku kuthetha ukuba amafutha avutha kwiqondo lokushisa eliphezulu.Oku kwenza ukuba injini isebenze shushu.Ngamanye amaxesha amatywina erabha kunye neengxowa zeplastiki azikwazi ukumelana namaqondo obushushu aphezulu abangela ukonakala.
Iingxaki kwiimoto zangoku:
Uninzi lweemoto zale mihla zineenkqubo zoluvo oluphambili zokulawula i-EGR kunye neempawu zegesi.Iimoto ezitsha zifumana, i-oxygen sensors, i-EGR flow meters, i-gas sensors ye-gas, njl njl, ukugcina iliso kwinkqubo ye-EGR.Ukuba i-EGR ivaliwe, i-ECM ibona ibhloko kwaye ivule imowudi eqhwalelayo elandelwa kukufudumala umqhubi ngokukhanya kwe-injini yokukhangela.Unokufumana i-torque ephantsi kwi-injini kodwa amandla aya kuthintelwa.
Ke ezi ziiProsand Cons ze-EGR Cima okanye iBlockinghope eya kuba luncedo kuwe.Ukuba uneminye imibuzo engakumbi, vele undishiyele umyalezo, kwaye ndonwabile ukunxibelelana.Ndizokubona.
