Exhaust gasi recirculation valve: kushanda uye zvinogona kuitika

Iyo EGR valve yakagadzirirwa kuderedza inokuvadza NOx emissions mupeturu uye dizeli injini, izvi zvinowanikwa nekuti inoderedza kupisa kwemoto mujini (magasi ane oxygen shoma uye, naizvozvo, kupisa kunenge kusinganyanyi kupisa, zvishoma sekudzima. moto). Nheyo yayo yakashoropodzwa nevamwe mainjiniya, vanotenda kuti zvinotungamira mukuvharika kweiyo yekudyara system (verenga: kutadza kunoenderana neEGR valve) ...

Ndapota cherechedza kuti iyi valve iripo pamainjini ose, angave peturu kana dhiziri (vazhinji vanotenda kuti inongowanikwa pamafuta emvura).

Nheyo yacho iri nyore, sezvo tiri kutaura nezvayo pombizve mamwe magasi ekuburitsa mumakamuri ekupisa... Chikamu chegasi chinobaiwa chinosiyana kubva 5 kusvika 40% zvichienderana nekushandiswa kweinjini (iyo inopedza gasi recirculation valve inongoshanda pakaderera kumhanya). Mhedzisiro yeizvi kupisa kupisa mumasilinda nekudzikisa huwandu hweokisijeni, iyo inoderedza Nox (

iyo yekupedzisira inoumbwa kunyanya sezvo kupisa kwekupisa kwakakwira

).

Muchokwadi, zvichienderana nekumhanya kweinjini, vharuvhu inotungamira yakawanda kana shoma gasi kuburikidza nediki diki / inofambiswa valve inodzorwa nekombuta. Zvakare, iyo yekupedzisira inonamira kana sisitimu yakavharwa nesoot yakawandisa (vanhu vasingamboise injini yavo pashongwe uye vanonyanya kuvharirwa kunzvimbo dzemumaguta vanotsigira chiitiko ichi). Izvi zvinowanzokwana kuti zvijeke, asi zvibvumirano zvakawanda hazvinetse zvakanyanya, kungozvishandura (zvinounza zvishoma zvishoma ...). Vamwe vatyairi vanototungamira patsanura (iyo maneuver) kuti usafanirwa kutarisana nayo zvakare (chenjerera, zvisinei, izvi zvinogona kukonzera kusagadzikana kwemagetsi, nekuti komputa yakagadzirirwa kushanda nayo, uye kubva pakuona kwetsika, iyi ivhareji, nekuti mota inosvibisa. zvimwe).

Ndapota cherechedza kuti iyi sisitimu haichakwanisi kuderedza NOx mazinga zvakakwana kuti asangane nezvipingamupinyi zvezvakatipoteredza. Ipapo mamwe masisitimu anooneka, akadai, semuenzaniso, SCR PSA (rudzi rwechigadziriso chinoshandisa AdBlue kushandura NOx kuita makomisheni akachengeteka).

Sei uchidzikisa kupisa kwekupisa?

Kupisa kwekushisa kwakanyanya kunokonzeresa kukurumidza kupfeka injini uye NOx kuumbwa, nekuti kana nitrogen yakanyanya kupisa (ndinokuyeuchidza kuti mweya une 80% yayo ...), inoshanduka kuita nitrogen oxides semhedzisiro yeoxidation (mazwi akajeka. ) Uye ndiwo manitrogen oxides aya, akasiyana uye akasiyana, atinodaidza kuti Nox (x inoshanduka nekuti kune akawanda maokisijeni akasiyana: NO2, NO, N2O3, nezvimwewo). Nekuda kweizvozvo, tinozvibatanidza kuita imwe nzira yakasiyana. Aihwax).

Asi nei tembiricha ichifanira kunyanya kukwirira? Zviri nyore, nekuti neinjini dzemazuva ano tinoedza kuchengetedza kushandiswa kwemafuta kwakaderera sezvinobvira. Uye nokuda kweizvi, zvinonzwisisika zvinodikanwa kupa zvivharo nemafuta mashoma sezvinobvira, izvo, naizvozvo, zvinotungamirira kumusanganiswa wakaonda: kushayikwa kwemafuta kuenzaniswa nemhepo. Uye nekuda kwejekiseni rakananga, musanganiswa wakaonda unofarirwa kupfuura nakare kose ... Ndinoda kuratidza kuti iyo yakaonda musanganiswa, iyo inopisa kupisa, uye saka yakawanda NOx (inogumbura zvakanyanya).

Kazhinji pane imwe chete EGR valve (ikozvino mavharuvhu maviri ari kuwanda), dhayagiramu inoratidza kuti maviri anofanira kunge akakwana sezvinobvira. Mutsvuku ndiyo inopera, uye mubhuruu ndiyo inotora mhepo. Pano tinogona kuona zvakajeka kuti EGR valve iri pamberi pekugadzirwa kwesoti yakabatana nemagasi ekupedza. Kushandiswa kwechigadzirwa chakawedzerwa kumafuta kana kuoiri kunogona kubatsira kudzivirira plugging izvo zvinozodzivirira kufamba kwemhepo, asi imhando yepombi inozoita kana isingaite kuvharika nekuti iri pazasi uye inogara ichimhanya painomhanyisa zvakanyanya. . vatyairi vekutya vanoshandisa chikwidziso vane zvishoma zvekunetsekana nazvo (kucheneswa kwenguva dzose kwaunogona kuita kuchaita kuti igare kwenguva refu kana madhiraivha ako achifarira kuvhara). Iyi valve ine simba rekutsausa (chisarudzo chinoitwa nekombuta) chikamu chemagasi kumhepo inotora, magasi ayo anotakura tsvina padhiziri, nekuti soot ine mafuta uye gobvu. Zviripachena, kune akawanda akasiyana anovaka (kunyanya iyo yakaderera yekumanikidza dunhu, iyo isingawanikwe kwese kwese), saka usashamisika kana paine musiyano mudiki pakati pezvaunoona pamota yako nezvaunoona pano.
