Izimpawu ze-Solenoid Enephutha noma Eyiphutha Ye-EGR

Izimpawu ezijwayelekile zihlanganisa izinkinga zokusebenza kwenjini ezifana namandla ancishisiwe nokusheshisa, ukushaya noma ukushaya enjinini, kanye nokukhanya kwenjini yokuhlola okuzayo.

Uhlelo lwe-EGR, olwaziwa nangokuthi uhlelo lwe-EGR, luwuhlelo lwegesi ekhishwayo olusetshenziswa ezimotweni eziningi ezisemgwaqeni namaloli. Inhloso yawo wukuzungeza amagesi e-exhaust aphume enjini abuyele endaweni edonsayo ukuze aphinde ashiswe. Lokhu kunciphisa inani le-oxygen engena enjinini ngokufaka enye yayo ngamagesi angenayo, okunciphisa amazinga e-NOx namazinga okushisa engxube.

Uhlelo lwe-EGR lulawulwa yi-EGR control solenoid. Uma i-solenoid yokulawula i-EGR icushiwe, iphasishi liyavuleka lapho amagesi e-exhaust angena khona ekuthatheni okuningi. I-solenoid ye-EGR ilawulwa yikhompuyutha yenjini futhi ivulwe ngesikhathi esithile ukuze kuzuzwe ukusebenza kwenjini okungcono kakhulu, ukusebenza kahle kanye nokukhipha umoya.

I-solenoid ye-EGR ingenye yezingxenye eziyinhloko zesistimu ye-EGR futhi noma yiziphi izinkinga ngayo zingabangela ukuthi uhlelo lungasebenzi, okungaba inkinga enkulu ezifundazweni ezinemithetho eqinile yokukhipha umoya. Ngokuvamile, inkinga nge-EGR control solenoid idala izimpawu ezimbalwa ezingazisa umshayeli ngenkinga engaba khona okufanele ixazululwe.

1. Izinkinga ngokusebenza kwenjini

Esinye sezibonakaliso zokuqala zenkinga engenzeka nge-solenoid yokulawula ye-EGR yizinkinga zokusebenza kwenjini. Uma i-solenoid ye-EGR inezinkinga ezithile, ingase ibangele ukuthi isilinganiso sikaphethiloli somoya esishunwe kahle sisethwe kabusha. Lokhu kungaholela ekuncipheni kwamandla, ukusheshisa, ukonga kukaphethiloli, kanye nokwanda kwesisi esikhishwayo.

2. Injini iyakhala noma ingqongqoza

Olunye uphawu lwenkinga engaba khona nge-EGR control solenoid valve umsindo ongqongqozayo noma ongqongqozayo enjinini. Uma i-solenoid ye-EGR ihluleka, ingakhubaza uhlelo lwe-EGR ku-EGR. Kwezinye izinjini, lokhu kungaholela ekwenyukeni okukhulu kwama-cylinder nama-exhaust gas okushisa. Amazinga okushisa aphakeme kakhulu amasilinda angabangela injini inyakaze futhi ikhenceze, okungadala umonakalo omkhulu wenjini uma inganakwa.

3. Hlola ukukhanya kwenjini kuyakhanya.

Isibani se-Check Engine esikhanyayo singolunye uphawu lwenkinga noma inkinga nge-EGR control solenoid. Uma ikhompuyutha ithola inkinga ngesistimu ye-solenoid, isekethe, noma ye-EGR, izokhanyisa ukukhanya kwenjini ukuze yazise umshayeli ngenkinga. I-solenoid ye-EGR engalungile ingabangela amakhodi amaningi enkathazo, ngakho-ke kunconywa kakhulu ukuthi uskene ikhompuyutha yakho ukuze uthole amakhodi enkathazo.

I-EGR control solenoid ingenye yezingxenye ezibaluleke kakhulu zohlelo lwe-EGR. Ngaphandle kwayo, uhlelo lwe-EGR ngeke lukwazi ukuphinda lujikeleze kahle amagesi akhipha umoya, okungaholela ezinkingeni zokusebenza kwenjini ngisho nokukhishwa kwegesi. Ngalesi sizathu, uma usola ukuthi i-EGR control solenoid ingaba nenkinga, cela imoto yakho ihlolwe uchwepheshe onjenge-AvtoTachki ukuze kutholwe ukuthi ingabe i-solenoid kufanele ishintshwe.
