I-valve ye-recirculation yegesi ephumayo: umsebenzi, impilo yesevisi kanye nentengo
Okuqukethwe
I-valve ye-EGR ukudlala okusebenza ukunciphisa ukukhishwa kokungcola emotweni yakho. Lena ivalvu evula futhi ivale ukuze iphinde ifake amagesi e-exhaust ohlelweni lomjovo wenjini. Ivalvu ye-EGR iyimpoqo ezimotweni zikadizili futhi iya ngokuya ifakwa ezinjinini zikaphethiloli.
🚗 Isebenza kanjani ivalvu yokukhipha igesi ephumayo?
La vanne EGR (Exhaust Gas Recirculation) uhlelo lokunciphisa ukukhishwa kwamagesi angcolisayo emkhathini. Ngempela, kusukela ngo-2000, i-European Union iye yaqinisa imithetho yokukhipha umoya (i-Euro 6 standard) ngokukhishwa kwegesi okuphezulu ngekhilomitha ngalinye.
Isibonelo, ngo-2009 izinga elivunyelwe lalingu-180 mg/km, futhi ngo-2019 lalingu-117 mg/km. Ngakho-ke, ukuze kuncishiswe inani lamagesi angcolisayo akhishwa izimoto, abakhiqizi baye benza i-valve ye-EGR.
Ukusebenza kwayo kulula: i-valve yokukhipha igesi ephumayo ivumela kabusha igesii-échappement ukunciphisa inani le-CO2 elikhishelwa emkhathini. Ngakho-ke, u-5% kuya ku-35% wamagesi e-exhaust asetshenziswa kabusha injini.
Ngobuchwepheshe, kumane nje valve ekhipha noma evalela amagesi akhipha umoya ukuze aphinde ajovwe enjinini. Ivalvu yokukhipha igesi ephumayo iyadingeka kuzo zonke izimoto zikadizili ngoba yizona ezingcolisa imvelo kakhulu, ikakhulukazi uma injini ingakashisi.
Phela uma injini kadizili isebenza ngesivinini esiphansi noma ingakashisi, amanye amagesi akhipha umoya awashi. I-nitrogen oxide eyeqile kanye nezinhlayiya ezinhle (isikali) bese zikhishelwa emkhathini.
Ukuze ugweme lokhu futhi unciphise ukukhishwa kwamagesi angcolisayo, izimoto zifakwe i-valve ye-EGR, eqondisa kabusha amanye amagesi e-exhaust ohlelweni. izijovo.
Abuye ashiswe okwesibili futhi aqukethe amagesi angcolisayo amancane. Nokho, lesi simiso sine-drawback: sivame ukungcolisa uhlelo lomjovo ngokuhamba kwesikhathi. Ngokufanayo, i-valve yokubuyisela igesi ephumayo ngokwayo ingaba ngcolile futhi ivaleke, iyenze ingasebenziseki.
Uma i-valve yakho ye-EGR ivalekile endaweni evaliwe, imoto yakho izongcolisa kakhulu. Uma ibambeka endaweni evulekile, uhlelo lokuthatha lungalimala futhi luvaleke. Ngakho-ke kubalulekile ukusevisa kahle i-valve ye-exhaust gas recirculation.
🗓️ Ingakanani impilo yesevisi yevalvu yokukhipha igesi ephumayo?
Impilo yesevisi ye-valve ye-exhaust gas recirculation iyahlukahluka. Ngakho-ke, kunconywa ukuthi ubhekisele kulogi yesondlo yomkhiqizi. Nokho, phawula ukuthi ngokwesilinganiso i-valve yokukhipha igesi ephumayo idinga ukushintshwa. njalo nge-150 km mayelana.
Impilo yesevisi ye-valve ye-exhaust gas recirculation nayo incike kakhulu endleleni oyisebenzisa ngayo imoto yakho. Impela, uma ushayela edolobheni kuphela, ivalvu yakho yokukhipha igesi ephumayo ivaleka ngokushesha, ngoba kukuma-revs aphansi lapho izinjini zikhiqiza ukungcola okuningi kanye nekhabhoni.
Uma i-valve yakho ye-EGR ivalekile noma ingasasebenzi, ungase uhlangabezane nezinkinga ezimbalwa:
- Ukulahlekelwa amandla ;
- Ukulawula kobuchwepheshe wenqaba ;
- Ukukhishwa kwentuthu emnyama ;
- Isibani sesexwayiso sokuphuma kwenjini kwavutha ;
- Umshini Wokulusa Izinkomo ngesivinini esiphansi.
Ngakho-ke, kubalulekile kuwe kanye nemoto yakho ukukhulisa impilo ye-valve ye-EGR. Ukuze wenze lokhu, kuhle ukushayela njalo ngesivinini esikhulu emgwaqeni. Impela, lapho injini yakho iphakanyiselwa phezulu, izosusa noma iyiphi ikhabhoni ebhajwe kusistimu yokukhipha umoya.
Ngokufanayo, ukwehla ikuvumela ukuthi uhlanze kahle sonke isikali esiqoqwe ohlelweni. Okokugcina, kunezithasiselo okufanele zengezwe kuphethiloli wakho ezizohlanza isistimu yokukhipha umoya futhi ikakhulukazi i-valve ye-EGR.
Qaphela ukuthi i-valve ye-EGR eyonakele ingadala izinkinga zobuchwepheshe njengoba yonke injini izovaleka. Ngakho-ke, kubalulekile ukuthi ungathathi le nkinga kalula futhi uyixazulule ngezimpawu zokuqala ezibonakalayo.
💰 Ibiza malini ivalvu yokukhipha igesi ephumayo?
Uma isibani sokulawula ukungcola sikhanya, sekuyisikhathi sokushintsha noma ukuhlanza i-valve ye-EGR. Sicela uqaphele ukuthi intengo ye-valve ye-EGR ihluke kakhulu: i-valve ye-EGR ingahluka kakhulu kusuka kumodeli yemoto eyodwa kuya kwenye.
Bala ngokwesilinganiso kusuka ku-100 kuya ku-400 euros (zabasebenzi) shintsha i-valve ye-EGR. Umehluko wentengo ungenxa yobuchwepheshe be-valve yokukhipha igesi ephumayo kanye nendawo yayo.
Ngempela, kwezinye izimoto, ukufinyelela ku-valve yokuvuselela igesi ephumayo kunzima kakhulu ngakho-ke kudinga ukususwa kwezinye izingxenye eziningi ukuze kutholakale ukufinyelela. Ngakho ungamangali uma amanani ehluka kakhulu ukusuka kwenye imoto ukuya kwelandelayo.
Isibonelo, ku-Renault Clio 4, udinga ukulindela isilinganiso sama-euro angu-80 ukuze ungene esikhundleni sevalvu yokukhipha igesi ephumayo, nakuFord C-Max, isilinganiso sama-euro angu-350. Intengo ye-valve ye-EGR nayo ihluka kakhulu kuye ngobuchwepheshe obusetshenzisiwe.
Ngempela, kunezinhlobo ezahlukene ze-valve ye-EGR: ama-valve e-recirculation yegesi ephezulu yokucindezela okukhulu и umfutho ophansi wokukhipha ama-valve e-gas recirculation. Amavalvu e-EGR avame kakhulu amavalvu omfutho ophezulu akha ulayini wokudlula usuka exhaust manifold ukuya kokuningi okukhiphayo. Ingcindezi iphezulu ngoba ivalvu ye-EGR itholakala ezansi nomfula.
Ngakolunye uhlangothi, ama-valve okukhipha igesi okucindezelwa okuphansi atholakala ngaphansi komugqa wokuqeda. Bese bebuyisela amagesi ku-turbocharger hhayi ku-multifold intake. Ngokufanayo, bavame ukuhlonyiswa ngesibandisi ukuze banciphise izinga lokushisa lamagesi abuyela enjinini.
Ekugcineni, ama-valve e-EGR cishe ayikho konke namuhla. Amandla ukwenza lula inkinga yokuvula nokuvala i-valve. Kuze kube yiminyaka yawo-2000, ama-valve ayevame kakhulu amathayi.
Qaphela ukuthi abanye abantu banquma ngokuphelele susa i-valve yokukhipha igesi ephumayo... Kodwa kwenqatshelwe ngokuphelele ukwenza kanjalo ngoba imoto ayisahlangabezani nezindinganiso zomkhiqizi zokulwa nokungcola. Ngokufanayo, ngeke udlule hlola lobuchwepheshe ukuthi ingabe uyisusile yini i-valve yokubuyisela igesi ephumayo.
