Ukuqonda ukuba kutheni imibhobho ye-EGR ishushu

Unokuzibuza ukuba kutheniUmbhobho we-EGRkwisithuthi sakho kuba shushu kakhulu. Obu bushushu buphumela ekujikelezweni kwakhona kweegesi zokukhupha ubushushu obuphezulu. Ezi gesi zidlala indima ebalulekileyo ekunciphiseni ukukhutshwa ngokuthoba ubushushu bomxube wokuthatha, okunceda ukunciphisa ukukhutshwa kwe-NOx. Ukukwazi kwenkqubo ye-EGR ukufunxa ubushushu kunempembelelo ekusebenzeni kwayo ekulawuleni oku kukhutshwayo. Ukuqonda le nkqubo kunokukunceda ukuba uqonde ukubaluleka kokugcina inkqubo ye-EGR yesithuthi sakho ukuze isebenze kakuhle kunye neenzuzo zokusingqongileyo.

Umsebenzi we-EGR System

Inkqubo ye-Exhaust Gas Recirculation (EGR) idlala indima ebalulekileyo kwizithuthi zale mihla. Inceda ukunciphisa ukukhutshwa okuyingozi kunye nokuphucula ukusebenza kakuhle kwe-injini. Ukuqonda indlela esebenza ngayo le nkqubo kunokukunceda ukuba uqonde ukubaluleka kwayo ekugcineni indawo ecocekileyo kunye nesithuthi esisebenza kakuhle.

Injongo yeNkqubo ye-EGR

Injongo ephambili yenkqubo ye-EGR kukunciphisa ukukhutshwa kwe-nitrogen oxide (NOx). Iigesi ze-NOx zinegalelo elikhulu kungcoliseko lomoya kunye nomsi. Ngokuphinda kujikelezwe inxalenye yegesi ephumayo ibuyele kuninzi lwe-injini yokuthatha, inkqubo ye-EGR yehlisa ubushushu bokutsha. Le nkqubo inciphisa ukubunjwa kwe-NOx ngexesha lokutsha.

Iziphumo zoPhando lwezeNzululwazi:

• IiNkqubo ze-EGR kwiiNjini zoKutsha zaNgaphakathigxininisa ukuba i-EGR inciphisa ngokufanelekileyo ukungcoliseka komoya kwizothutho kunye nezicelo zemizi-mveliso.
• Ukusebenza kwe-EGR kuLawulo lwe-NOx lokuPhumaiqinisekisa ukuba i-EGR sisicwangciso esiqinisekisiweyo sokulawula ukukhutshwa kwe-NOx kwiinjini zedizili.

Ukongeza ekunciphiseni ukukhutshwa kwezinto ezikhutshwayo, inkqubo ye-EGR inokwandisa ukusebenza kakuhle kwamafutha. Ngokuhlambulula umxube wamafutha omoya, yehlisa ioksijini ekhoyo yokutsha, nto leyo enokukhokelela ekuphuculweni kokusetyenziswa kwamafutha. Olu ncedo lubonakala ngokukodwa kwiinjini zedizili ezinomsebenzi onzima, apho iinkqubo ze-EGR zikhulisa inkqubo yokutsha ukuze kusebenze ukusebenza kakuhle kwamafutha.

Isebenza njani i-EGR System

Isixokelelwano se-EGR sisebenza ngokuthumela kwakhona inxalenye yerhasi yokuphuma ibuyele kubuninzi be-injini ethathayo. Le nkqubo ibandakanya amacandelo amaninzi, kubandakanywa ivalve ye-EGR, i-EGR epholileyo, kunye nombhobho we-EGR. I-valve ye-EGR isebenza njengebhuloho phakathi kokukhupha kunye ne-intake manifolds, ilawula ukuhamba kweegesi zokukhupha. Xa i-valve ivula, i-exhaust gases idlula kumbhobho we-EGR kwaye ingene kwi-manifold intake.

I-EGR cooler idlala indima ebalulekileyo kule nkqubo. Ipholisa i-exhaust gases ngaphambi kokuba iphinde ingene kwi-injini, inciphisa ngakumbi ukukhutshwa kwe-NOx. Ukupholisa umjelo we-EGR kunokwandisa kakhulu ukusebenza kwenkqubo kulawulo lokukhutshwayo.

Iziphumo zoPhando lwezeNzululwazi:

• Izinto eziluncedo kwiiNkqubo zale mihla ze-EGRibonisa ukuba iinkqubo ze-EGR zanamhlanje azigcini nje ukunciphisa ukukhutshwa kwe-NOx kodwa ziphucula impendulo ye-throttle kunye nokwandisa ixesha elide le-injini.
• UPhuculo lwe-EGR yokuNcitshiswa koMkhukoigxininisa ukubaluleka kokumisela ixesha lokuvula ivalve ye-EGR yoxinzelelo oluphantsi lokunciphisa ukukhutshwa okusebenzayo.

Umbhobho we-EGR yinxalenye ebalulekileyo kule nkqubo. Ithwala iigesi zokukhupha ezishushu ukusuka kwi-exoust manifold ukuya kwi-intake manifold. Ngenxa yobushushu obuphezulu bezi gesi, umbhobho we-EGR unokuba shushu ngokugqithisileyo. Obu bushushu sisiphumo sendalo sokusebenza kwenkqubo ye-EGR kwaye igxininisa ukubaluleka kokusebenzisa imathiriyeli ehlala ixesha elide ekwakhiweni kwayo.
