Nzira yekutsiva sei exhaust gas recirculation (EGR) valve

Motokari yako inogona kuratidza Cheki Engine mwenje, inogona kusashanda nemazvo, kana kusapasa muyedzo wekubuda kwenzvimbo. Izvi zvinogona kuva zvimwe zvezviratidzo zvinowanzoitika zveEGR yakakundikana (exhaust gas recirculation) valve. EGR haingokanganisa kuburitsa kwemotokari yako chete, asi inogona kukonzera matambudziko akanyanya ekubata mota yako. Kuziva zvinoitwa neEGR valve uye kuti ungazviongorora sei zvinogona kukubatsira kuchengetedza imwe mari nekuzvigadzirisa iwe pachako, kana kukubatsira kuti uve mutengi ane ruzivo.

Chikamu 1 che3: Kunzwisisa chinangwa cheEGR valve uye kuti inoshanda sei

Iyo EGR valve kana EGR vharafu chikamu chemotokari yako inopedza simba. Chinangwa chayo chikuru kudzikisa NOX (oxide yenitrogen) inoburitsa injini yako. Izvi zvinowanikwa kuburikidza nekudzorerazve gasi rinopera kumotokari, iyo inogadzirisa kutonhora kwekamuri inopisa, uye inobvumirawo kupisa kwemoto kutanga zvakare pamhepo yekutsvaira gasi recirculation, iyo inoderedza kuwanda kwemafuta asina kupiswa mairi.

Kune marudzi maviri eEGR mavharuvhu, emagetsi uye manyorero. Iyo yemagetsi vhezheni ine solenoid inobvumira komputa kuvhura uye kuvhara kana ichidiwa. Iyo vhezheni yemanyorero inovhura kana injini yekuvharira ichiiswa pairi, yobva yavhara kana ichiburitsa vacuum. Pasinei nokuti ndeipi yaunayo, kushanda kwehurongwa kwakafanana. Komputa yemotokari inodzora kuvhurwa nekuvhara kweEGR valve zvichienderana nekumhanya kwemotokari uye tembiricha yeinjini.

Pamotokari zhinji, EGR valve inongoshandiswa kana injini ichidziya kusvika kune yakajairika tembiricha yekushanda uye mota ichifamba nekumhanya kwemugwagwa. Kana iyo system isiri kushanda nemazvo, inogona kutungamira kune chimwe chinhu chakareruka senge Cheki Engine mwenje ichiuya, kune chimwe chinhu chakakomba sekumisa injini.

Chikamu 2 che3: Kuongorora Mhosva EGR Valve

Iyo EGR valve inogona kukundikana nekuda kwezvikonzero zvakasiyana. Kana izvi zvikaitika, zvinogona kukonzera huwandu hwezviratidzo. Kana EGR valve ikakundikana, kazhinji inokundikana mune imwe yenzira mbiri: inonamira yakavhurika kana kuti inonamira yakavharika. Zviratidzo izvi zvinogona kunge zvakafanana nemamwe matambudziko emotokari, saka kuongororwa kwakakodzera kunokosha.

Tarisa kana mwenje weinjini wakabatidzwaA: Kana EGR valve ikakundikana, inogona kukonzera kuti Cheki Engine chiedza chiuye. Kana mwenje wakabatidzwa, komputa inoda kutariswa kuti ione macode. Kana paine EGR low flow code, zvinoreva kuti EGR valve haisi kuvhura.

Kombiyuta inogona kuziva kana EGR valve iri kuvhurwa nekuchinja kwainoona mumasensa okisijeni kana vharuvhu yakavhurika. Iwe unogonawo kugamuchira kodhi isina kururama yevheji yeEGR valve, iyo inogona kuratidza dambudziko redunhu kana kukundikana kwevhavha. Kodhi yakaonda yemusanganiswa inogonawo kuoneka kana EGR vharafu yakanamira yakavhurika. Kana EGR valve yakanamira yakavhurika, mweya usingashandiswi uchapinda muinjini, zvichiita kuti komputa ione mweya wakawandisa mujini.

Zvakaipa zvisina basa: Kana iyo EGR valve yakanamira panzvimbo yakavhurika, inokonzeresa kubuda kwevacuum. Izvi zvinozoita kuti injini ishande nguva nenguva nekuti komputa haizokwanisa kunyatsoona mweya wakawandisa.

Kana chimwe chezviratidzo izvi chichionekwa, valve inofanira kuongororwa. Zvichienderana nerudzi rwemotokari, zvichaonekwa kuti ichaongororwa sei.

EGR Yakashaikwa / Yakaderera Kuyerera Kodhi: Izvi zvinoreva kuti hapana gasi rakakwana rinopera rinopinda injini kana EGR valve yakavhurwa. Izvi zvinogona kunge zvichikonzerwa nezvikonzero zvakawanda. Iko kugona kuongorora imwe neimwe yadzo kuchakubatsira iwe kuwana dambudziko.

• Electronic EGR valve: Ivhavha yeEGR inogona kunge isina kukwana kana kuti ine simba rekutonga redunhu. Nzira yakanakisa yekuongorora izvi ndeye scanner kutanga. Neinjini inomhanya, EGR valve inogona kuvhurwa nekuvharwa, uye unogona kutarisa kushanda kwayo kwakaringana. Kana iyo isingashande, saka unofanirwa kutarisa EGR valve ine ohmmeter. Kana valve ikasangana nemigumisiro yakaipa, inofanira kuchinjwa. Kana zvinhu zvose zvakarongeka, dunhu rinofanira kuongororwa ne voltmeter.

• Manual EGR valve: Manual EGR valve kana kutonga kwayo solenoid kana kukundikana kwedunhu kunogona kuvapo. EGR valve inogona kutariswa nepombi yevacuum kuona kana yakanamira panzvimbo yakavharwa. Neinjini iri kushanda, unogona kushandisa pombi yekutsvaira kuisa vacuum kune EGR valve. Kana injini isingashande ichichinja kana vacuum yaiswa, vharuvhu yakanaka. Kana zvisina kudaro, zvino inoda kuchinjwa. Kana iyo EGR valve yakanaka, tarisa iyo control circuit uye solenoid.

• Yakavharwa EGR chiteshi: Ivhavha yeEGR inogonawo kuva yakanaka paunowana kodhi yedambudziko rekuyerera. Iyo EGR ndima dzinobatanidza kupera kune inotorwa dzinowanzovharwa nekabhoni kuvaka. Kazhinji EGR valve inogona kubviswa uye ndima dzakatariswa kuti dzipiwe mari. Kana pane kuunganidza, saka inofanira kutanga yabviswa uye wozoedza zvakare motokari.

Kana dambudziko nemotokari richikonzerwa nekodhi yakaonda kana dambudziko risina basa, izvi zvinoratidza kuti valve haisi kuvhara. Ivhavha inofanira kubviswa uye zvikamu zvemukati zvinogona kuongororwa kuti zvione kana zvichifamba zvakasununguka. Kana zvisina kudaro, zvino inoda kuchinjwa.

Chikamu 3 che3: EGR vharafu kutsiva

Kana iyo valve yaonekwa kuti haina kukanganisa, inofanira kuchinjwa.

Zvinhu zvinodiwa

• EGR vharafu
• Ratchet ine zvigadziko
• Wrench (inogadziriswa)

Danho 1: Paka mota yako panzvimbo yakati sandara.. Paka panzvimbo yakaenzana uye isa bhureki rekupaka. Rega injini itonhore.

Danho rechipiri: Tsvaga EGR valve. Iyo EGR valve inowanzowanikwa pane yakawanda yekutora. Chinamira chinoburitsa mhepo pasi pevhavha chinogona kukubatsira kuwana vharafu.

Danho rechitatu: Sunungura pombi yekupedza. Shandisa chipanera kuti usunungure pombi yepombi yakasungirirwa kuEGR valve.

Danho rechitatu: Bvisa mabhaudhi. Uchishandisa ratchet uye socket yakakodzera, bvisa mabhaudhi akabata vharafu kune inopinza manifold uye bvisa vharafu.

Danho rechishanu: Isai valve itsva. Isai vharafu idzva munhevedzano kurongeka uye simbisa mabhaudhi ayo anokwirisa kune zvakatemwa nemugadziri.

Mushure mekuisa itsva EGR valve, inogona kuongororwa zvakare. Kana kutarisa uye kutsiva EGR valve kunoratidzika kunge kwakaoma kwauri, unofanira kutsvaga rubatsiro rwemakanika ane ruzivo anogona kutsiva EGR valve kwauri.
