EGR imayimira mpweya wotulutsa mpweyakubwerezanso, lingaliro lowongolera mpweya wamagalimoto omwe amagwiritsidwa ntchito mumafuta amafuta ndi dizilo.Chithunzi cha EGR,zomwe zimagwira ntchito mosiyana malinga ndi zaka za galimotoyo komanso ngati imagwiritsa ntchito mafuta a petulo kapena dizilo, ndi gawo lofunika kwambiri la galimotodongosolo lotopetsa ndi injini thanzi.
Ubwino ndi kuipa kwa EGR Kuletsa kapena Kuchotsa:
EGR ndi zida zowongolera utsi zomwe zimapangidwa ndi opanga magalimoto, zomwe zimagwira ntchito yowongolera gawo lina la gasi wotulutsa mpweya kupita ku injini.Monga ntchito ya EGR ndikuchepetsa mphamvu ya injini pamiyezo yotulutsa mpweya, imachepetsanso moyo wa injini.Chifukwa chake ndizofala kutsekereza valavu ya EGR kuti galimotoyo ikhale yabwino.
Choyamba tiyeni tikambirane za Ubwino wotsekereza valavu ya EGR:
Kuletsa EGR kudzabwezeretsanso mphamvu ya injini mpaka pachimake chomwe chilipo.Izi zikutanthauza kuti mafuta ochepa amafunikira kuti mukhale ndi mphamvu yofanana yomwe ikupezeka kuchokera ku injini.
Pamene mphamvu ya injini imasinthidwa kukhala yabwino kwambiri poletsa mpweya woipa wa carbon dioxide kulowanso mu injini, imakhala ndi mphamvu yabwino pa pistons pa RPMs yotsika.RPM imayimira kusintha kwa mphindi imodzi, ndipo izois amagwiritsidwa ntchito ngati muyeso wa kuthamanga kwa makina aliwonse pa nthawi yake.M'magalimoto,RPMimayesa kangati chibowo cha injini chimapanga kuzungulira kokwanira mphindi iliyonse, ndipo pamodzi ndi iyo, kangati pistoni iliyonse imakwera ndi kutsika mu silinda yake.Simuyenera kugwira ntchito pamagiya ambiri kuti mudutse ndikuwongolera magalimoto amtawuni.
Pamene EGR yatsekedwa, mwaye wa carbon ndi ma particulate amachoka kuti asalowenso mu injini.Izi zimapangitsa injini yochuluka, pistoni ndi zigawo zina kukhala zoyera.Injini yoyera imayenda bwino ndipo imakhala ndi moyo wogwira ntchito kwambiri poyerekeza ndi yomwe ili ndi tinthu ta kaboni tambiri timene timayenda mu injiniyo.
Mwaye wa kaboni umagwira ntchito ngati chinthu chonyezimira ndipo umawonjezera kung'ambika pazigawo zosuntha.EGR ikatsekeka, injini imayamba kugwira ntchito bwino kwambiri, izi zimapangitsa kuyaka koyenera mu silinda iliyonse ndikuwotcha mafuta moyenera.
Pamene mafuta amayaka bwino, sipadzakhala mafuta osapsa omwe angatuluke mu injini.Izi zimachepetsa kupanga utsi kuchokera ku injini.Pamene mpweya woyera umakokedwa ndi injini, kukhudza pang'ono mu accelerator pedal kukupatsani mphamvu zokwanira kuti mukwaniritse zomwe mukufuna.Izi zimakupangitsani kumwetulira pankhope yanu ndikupangitsa kuti muyende mosavuta mumzinda kuti mudutse magalimoto ena.
Kuletsa EGR kumachepetsa kupanga mwaye wa kaboni chifukwa umawotcha mafuta bwino ndi mpweya wochuluka wa okosijeni.Izi zimapewa midadada yoyambirira mu DPF ndi chosinthira chothandizira.
Tsopano tiyeni tiwone Zoyipa zakuchotsa EGR:
Monga cholinga cha EGR ndikuchepetsa mpweya wotuluka m'galimoto, chifukwa chotsekeka chake chimatha kuwona mwaye wocheperako koma chimawonjezera kupanga kwa NOx, Carbon monoxide, ndi zina zomwe zimawononga chilengedwe.
Kuletsa EGR kudzawonjezera mphamvu ya injini.Izi zikutanthauza kuti, kuyatsa mafuta moyenera.Monga kuyaka koyenera komanso kwamphamvu kumatha kuwonjezera phokoso la injini ndi kugwedezeka pang'ono.Pamene EGR yatsekedwa, kutentha kwa moto kumawonjezeka.Kutentha kotentha kumeneku kungapangitse phokoso logogoda.
Imakhudza Galimoto Yoyendetsedwa ndi Turbo:
EGR ikatsekedwa, gasi wopopa kwambiri wokhala ndi kutentha kwakukulu amayenera kudutsa pa charger ya turbo, kupangitsa kuti igwire ntchito molimbika ndikuchepetsa moyo wake kukhala waufupi.
Kuletsa EGR kumapangitsa kuti injini igwire bwino, zomwe zikutanthauza kuti mafuta akuyaka pa kutentha kwakukulu.Izi zimapangitsa injini kuthamanga kwambiri.Nthawi zina zosindikizira za mphira ndi zomangira za pulasitiki sizingathe kupirira kutentha kotereku kumapangitsa kuwonongeka.
Mavuto ndi magalimoto amakono:
Magalimoto ambiri amakono ali ndi makina apamwamba kwambiri owongolera EGR ndi gasi.Magalimoto atsopano amapeza, masensa okosijeni, ma EGR oyenda mita, masensa kutentha kwa gasi ndi zina, kuyang'anira dongosolo la EGR.Ngati EGR yatsekedwa, ECM imazindikira chipikacho ndikuyambitsa limp mode ndikuwotha dalaivala ndi kuwala kwa injini.Mutha kupeza torque yotsika kuchokera ku injini koma mphamvuyo imakhala yochepa.
Chifukwa chake awa ndi Prosand Cons a EGR Chotsani kapena Blockinghope zomwe zingakhale zothandiza kwa inu.Ngati muli ndi mafunso enanso, ingondisiyirani uthenga, ndipo ndine wokondwa kulumikizana.Tiwonana.
