Izimpawu Zenzwa Enephutha noma Enephutha Yempendulo Yengcindezi ye-EGR
Okuqukethwe
Izimpawu ezijwayelekile zifaka izinkinga zokusebenza kwenjini njengokungenzi lutho nokuphelelwa amandla, ukwehluleka kokuhlolwa kokukhipha, kanye nokukhanya kwenjini okuzayo.
Izimoto eziningi zesimanje zifakwe i-exhaust gas recirculation system, esiza ukunciphisa ukukhishwa kwezimoto. Uhlelo lwe-EGR lusebenza ngokuphindaphinda amagesi e-exhaust abuyele enjinini ukuze kwehliswe izinga lokushisa lesilinda kanye nokukhishwa kwe-NOx. Uhlelo lwe-EGR lwakhiwe izingxenye ezimbalwa ezisebenza ndawonye ukufeza lo msebenzi. Ingxenye enjalo evame ukutholakala ezinhlelweni eziningi ze-EGR inzwa yempendulo yengcindezi ye-EGR.
Inzwa yempendulo yengcindezi ye-EGR, eyaziwa nangokuthi inzwa yempendulo yengcindezi ye-delta, iyinzwa ethola izinguquko zengcindezi kusistimu ye-EGR. Kanye nevalvu ye-EGR, ilawula ingcindezi ohlelweni lwe-EGR. Lapho inzwa yempendulo yengcindezi ye-EGR ithola ukuthi ingcindezi iphansi, ivula i-valve ye-EGR ukuze ikhulise ukugeleza, futhi ngokuphambene ivala i-valve uma ithola ukuthi ukucindezela kuphezulu kakhulu.
Njengoba ukufundwa kokucindezela okutholwe inzwa yokucindezela kwe-EGR kungenye yemingcele ebaluleke kakhulu esetshenziswa uhlelo lwe-EGR, uma kunezinkinga, kungabangela izinkinga ngohlelo lwe-EGR, okungaholela ezinkingeni zokuqhuba injini ngisho nokwanda kokukhishwa kwegesi. . Ngokuvamile, inkinga ngenzwa ye-EGR ye-pressure feedback ibangela izimpawu ezimbalwa ezingazisa umshayeli ngenkinga engaba khona edinga ukulungiswa.
1. Izinkinga ngokusebenza kwenjini
Enye yezimpawu zokuqala zenkinga yenzwa yengcindezi ye-EGR yizinkinga zokusebenza kwenjini. Uma inzwa yokucindezela kwe-EGR ithumela noma yikuphi ukufundwa okungamanga kukhompuyutha, ingabangela isistimu ye-EGR ukuthi ingasebenzi kahle. Isistimu ye-EGR engalungile ingaholela ezinkingeni zokusebenza kwenjini njengokungenzi kahle, ukudlidliza kwenjini, kanye nokuncipha kwawo wonke amandla nokusebenza kahle kukaphethiloli.
2. Ukuhlolwa kokukhipha okuhlulekile
Olunye uphawu lwenkinga engase ibe khona ngenzwa yokucindezela kwe-EGR ukuhlola okuphumayo okuhlulekile. Uma inzwa yokucindezela kwe-EGR inanoma yiziphi izinkinga ezithinta ukusebenza kwesistimu ye-EGR, ingabangela imoto ukuthi yehlule uhlolo lokukhishwa kwekhabhoni. Lokhu kubaluleke kakhulu ezifundazweni ezidinga imoto ukuthi iphumelele ukuhlolwa kokukhishwa kwegesi ukuze ibhalise imoto.
3. Hlola ukukhanya kwenjini kuyakhanya.
Olunye uphawu lwenkinga yenzwa yengcindezi ye-EGR ukukhanya kwe-Check Engine. Uma ikhompuyutha ithola noma iyiphi inkinga ngesignali yenzwa yokucindezela kwe-EGR noma isekethe, izokhanyisa ukukhanya kwe-Check Engine ukuze yazise umshayeli ngenkinga. Ukukhanya kwe-Check Engine kungabangelwa izinkinga ezihlukahlukene, ngakho-ke kunconywa kakhulu ukuthi uskene ikhompuyutha yakho ukuze uthole amakhodi enkathazo.
Inzwa yokucindezela kwe-EGR ingenye yezingxenye ezibaluleke kakhulu zesistimu ye-EGR ezimotweni ezihlonyiswe ngayo. Isignali ekhiqizwayo ingenye yemingcele eyinhloko esetshenziswa uhlelo lwe-EGR ukuze lusebenze, futhi noma yiziphi izinkinga ngalo zingathinta ukusebenza okuphelele kwesistimu. Ngalesi sizathu, uma usola ukuthi inzwa yakho ye-EGR pressure ingaba nenkinga, cela imoto yakho ihlolwe uchwepheshe onjenge-AvtoTachki ukuze kutholwe ukuthi ingabe inzwa kufanele ishintshwe.
