Indlela yokuhlanza i-valve ye-EGR

I-valve ye-EGR iyinhliziyo yesistimu ye-exhaust aftertreatment yenjini. I-EGR imfushane ku-Exhaust Gas Recirculation, futhi yilokho kanye ekwenzayo. Le divayisi emangalisayo ehambisana nemvelo ivula ngaphansi kwezimo ezithile zokusebenza kwenjini ...

I-valve ye-EGR iyinhliziyo yesistimu ye-exhaust aftertreatment yenjini. I-EGR imfushane ku-Exhaust Gas Recirculation, futhi yilokho kanye ekwenzayo. Lesi sisetshenziswa esimangalisayo esihambisana nemvelo sivula ezimeni ezithile zokusebenza kwenjini futhi sivumele amagesi e-exhaust ukuthi aphinde ajikelezwe enjinini okwesibili. Le nqubo inciphisa kakhulu ukukhishwa okuyingozi kwe-nitrogen oxides (NOx), okunomthelela omkhulu ekwakhekeni kwe-smog. Kulesi sihloko, uzothola ulwazi mayelana nomsebenzi we-valve ye-EGR, kanye nendlela yokuhlanza i-valve nokuthi kungani ngokuvamile idinga ukuhlanzwa noma ukushintshwa.

I-valve ye-EGR iphila impilo enzima. Eqinisweni, cishe ingenye yezingxenye eziyinkimbinkimbi kakhulu zenjini yesimanje. Ihlale ijeziswa ngamazinga okushisa ashisayo imoto engawenza futhi ivalwe yizinhlayiya zikaphethiloli ongashile, ezaziwa kangcono ngele-carbon. Ivalvu ye-EGR intekenteke ngokwanele ukuthi ingalawulwa isivacu senjini noma ikhompuyutha, kuyilapho ikwazi ukumelana nezinga lokushisa legesi ekhishwa yikhabhoni engu-1,000-degree njalo uma injini isebenza. Ngeshwa, kukhona umkhawulo kukho konke, kuhlanganise ne-valve ye-EGR.

Ngemva kwezinkulungwane zemijikelezo, ikhabhoni iqala ukufaka amadiphozithi ngaphakathi kwevalvu ye-EGR, ikhawulela ikhono levalvu ukwenza umsebenzi wayo njengomgcini-sango we-EGR. Lawa madiphozithi ekhabhoni aya ngokuya eba mkhulu kuze kube yilapho ivalvu ye-EGR iyeka ukusebenza kahle. Lokhu kungaholela ezinkingeni ezihlukahlukene zokusingatha, okungekho kuzo ezifiselekayo. Uma lokhu kungasebenzi kahle kwenzeka, kukhona amakhambi amabili ayinhloko: ukuhlanza i-valve ye-EGR noma ukufaka i-valve ye-EGR.

Ingxenye 1 kwezi-2: Ukuhlanza i-valve ye-EGR

Izinto ezidingekayo

• Amathuluzi esandla ayisisekelo (ama-ratchets, amasokhethi, amapulangwe, ama-screwdrivers)
• I-Carburetor ne-throttle cleaner
• I-gasket ye-scraper
• inaliti ekhaleni impintshisi
• Amagilavu ​​e-Latex
• Izibuko zokuphepha
• ibhulashi elincane

Isinyathelo 1 Khipha zonke izixhumi zikagesi.. Qala ngokukhipha noma yiziphi izixhumi zikagesi noma amapayipi axhunywe ku-valve ye-EGR.

Isinyathelo sesi-2: Khipha i-valve ye-EGR enjinini.. Ukuba yinkimbinkimbi kwalesi sinyathelo kuncike ohlotsheni lwemoto, kanye nendawo nesimo se-valve.

Ivamise ukuba namabhawudi amabili kuya kwamane ayibambe ku-multifold, ekhanda lesilinda, noma ipayipi lokukhipha umoya. Khulula lawa mabhawudi futhi ukhiphe i-valve ye-EGR.

Isinyathelo sesi-3: Hlola izimbobo zama-valve ukuze uthole ukuvaleka kanye namadiphozithi.. Futhi hlola amachweba ahambisanayo enjinini ngokwayo. Zivame ukuvaleka ngekhabhoni cishe njengevalvu uqobo.

Uma ivalekile, zama ukukhipha izingcezu ezinkulu zekhabhoni usebenzisa izinsimbi zekhala yenaliti. Sebenzisa i-carburetor ne-throttle body cleaner ngokuhambisana nebhulashi elincane ukuze uhlanze noma yiziphi izinsalela ezengeziwe.

Isinyathelo sesi-4: Hlola i-valve ye-EGR ukuze uthole amadiphozithi.. Uma i-valve ivalekile, ihlanze kahle nge-carburetor futhi i-click cleaner kanye nebhulashi elincane.

Isinyathelo sesi-5: Hlola umonakalo wokushisa. Hlola i-valve ye-EGR ukuze uthole umonakalo odalwe ukushisa, ubudala kanye nokwakheka kwekhabhoni.

Uma yonakele, kufanele ishintshwe.

Isinyathelo sesi-6: Hlanza i-EGR valve gasket.. Hlanza indawo ye-gasket ku-valve ye-EGR kanye nenjini nge-gasket scraper.

Qaphela ukuthi ungatholi izingcezu ezincane ze-gasket kumachweba we-EGR ohlangothini lwenjini.

Isinyathelo sesi-7: Faka esikhundleni se-EGR gaskets.. Uma yonke into isihlanziwe futhi isihloliwe, buyisela i(ama)gasket ye-EGR futhi uyinamathisele enjinini ekucacisweni kwefekthri.

Isinyathelo sesi-8: Hlola ukuvuza. Hlola ukusebenza ngokuhambisana nebhukwana lensizakalo yefekthri futhi uhlole ukuvuza kwevacuum noma i-exhaust.

Ingxenye 2 kwezi-2: Ukushintshwa kwevalvu ye-EGR

Amavalvu e-EGR ngezinye izikhathi angaba nenkinga ukushintshwa ngenxa yeminyaka, isimo, noma uhlobo lwemoto ngokwayo. Uma unobunzima ngezinyathelo ezingezansi, kuhlala kungcono kakhulu ukubona uchwepheshe.

Izinto ezidingekayo

• Amathuluzi esandla ayisisekelo (ama-ratchets, amasokhethi, amapulangwe, ama-screwdrivers)
• I-gasket ye-scraper
• Amagilavu ​​e-Latex
• Izibuko zokuphepha

Isinyathelo 1 Khipha noma yiziphi izixhumi zikagesi noma amapayipi.. Qala ngokukhipha noma yiziphi izixhumi zikagesi noma amapayipi axhunywe ku-valve ye-EGR.

Isinyathelo sesi-2: Susa amabhawodi avikela i-valve ye-EGR enjinini.. Ngokuvamile kukhona kusukela ezimbili kuya ezine, kuye ngokuthi imoto.

Isinyathelo sesi-3: Khwebula i-gasket material endaweni yokukhwelana. Gcina udoti ungangeni embobeni ye-EGR yenjini.

Isinyathelo sesi-4: Faka i-valve entsha ye-EGR kanye ne-valve gasket.. Faka i-gasket ye-valve ye-EGR entsha kanye ne-valve ye-EGR enjinini kuya ekucacisweni kwefekthri.

Isinyathelo sesi-5: Xhuma kabusha Amapayipi noma Izixhumi zikagesi.

Isinyathelo sesi-6: Hlola kabusha isistimu yakho. Hlola ukusebenza ngokuhambisana nebhukwana lensizakalo yefekthri futhi uhlole ukuvuza kwevacuum noma i-exhaust.

Amavalvu e-EGR alula endleleni asebenza ngayo, kodwa ngokuvamile akulula uma kuziwa ekushintsheni. Uma ungakhululekile ukufaka ivalve ye-EGR ngokwakho, yiba nomakhenikha oqeqeshiwe ofana ne-AvtoTachki esikhundleni se-valve ye-EGR.
