Izimpawu ze-Solenoid enephutha noma enephutha

Izimpawu ezijwayelekile zenkinga nge-EVAP canister purge solenoid yemoto zifaka ukungenzi lutho, ukuqalisa ubunzima, nokukhanya kwenjini yokuhlola okuzayo.

I-canister purge solenoid iyingxenye yokulawula ukungcola evame ukusetshenziswa ohlelweni lwe-fuel vapor emission control (EVAP) lwezimoto eziningi zesimanje. Izimoto zesimanje zifakelwe isistimu ye-EVAP esebenza ukunciphisa ukungcola okuhwamukayo okungavela ethangini likaphethiloli lemoto likhishwa njengentuthu. Isistimu ye-EVAP ithwebula lo mhwamuko ku-charcoal canister futhi iwusebenzise kabusha ukuze usetshenziswe njengophethiloli wenjini futhi ivikele ukungcola.

I-canister purge solenoid, ebizwa nangokuthi i-EVAP canister valve, inesibopho "sokuhlanzwa" kwesistimu ye-EVAP ngokusebenza njengeswishi evumela ukuthi umhwamuko ungene enjinini. Uma i-solenoid yokuhlanza ihluleka, izodala izinkinga ohlelweni lwe-EVAP, okuzophazamisa ukukhishwa kwemoto. Ngokuvamile, i-solenoid ehlulekile yokuhlanza ibonisa noma yiziphi izimpawu ezilandelayo ezingu-5 ezingase zixwayise umshayeli ngenkinga engase idinge isevisi.

1. Ukungenzi lutho okunzima

Esinye sezibonakaliso zokuqala ze-valve yokuhlanza i-canister embi ukungenzi lutho. Kulokhu, uzoqaphela ukuthi imoto ayizinzile ngenkathi imile noma ishayela ngesivinini esiphansi. Uma i-valve yokuhlanza i-canister ihluleka futhi ivuleka, izodala ukuvuza kwe-vacuum okungathinta isivinini kanye nekhwalithi yenjini uma ingenzi lutho. Ukuvuza kwe-vacuum kungase kubangelwe i-solenoid yokuhlanza ephukile noma eyonakele noma imaphi amapayipi anamathiselwe kuyo. Lokhu kudinga ukuxazululwa ngokushesha ngangokunokwenzeka, njengoba kungase kuholele ekumisweni okuphelele kwenjini.

2. Ukungasebenzi kahle kwenjini.

Ngaphezu kokungenzi lutho, imoto ene-EVAP canister purge valve embi izokhombisa izimpawu zokusebenza kabi kwenjini. Kungase kubonakale sengathi injini isebenza “ngokubuthakathaka” futhi ayiwakhiqizi amandla anele okusheshisa. Uma ushesha, uzozwa sengathi ucindezela i-pedal futhi uhamba kancane. Inqubo yokuvutha ephazamisekile ebangelwa i-solenoid yokuhlanza engalungile izoholela ekusheshiseni okunensayo okufanele kulungiswe ngokushesha.

3. Isiqalo esinzima

Olunye uphawu oluvame ukuhlotshaniswa ne-solenoid embi ye-canister purge solenoid kunzima ukuqala kwemoto. Futhi, uma ukuvuza kwe-vacuum kuwumphumela wohlobo oluthile lwenkinga nge-canister purge solenoid, kungabangela izinkinga ngokuqala okuthembekile kwemoto. Ukuvuza kwevacuum kuzongenisa umoya ongaphandle ongalinganisiwe enjinini, okungase kuphazamise isilinganiso sikaphethiloli womoya futhi kubangele izinkinga zokusebenza ngenxa yokuphazamiseka kwenqubo yokuvutha kwangaphakathi. Ekugcineni, injini ingase yenqabe nhlobo ukuqala.

4. Isibani se-Check Engine siyakhanya

I-solenoid embi ye-canister purge ingabangela ukukhanya kwe-Check Engine ukuthi kukhanye. Uma ikhompuyutha ithola noma iyiphi inkinga ngesekhethi ye-solenoid yokuhlanza noma isignali, izokhanyisa ukukhanya kwe-Check Engine ukuze yazise umshayeli ukuthi kunenkinga. Ukukhanya Kwenjini Yokuhlola kungase futhi kubangelwe ezinye izinkinga ezihlukahlukene, ngakho-ke kuwumqondo omuhle ukuskena imoto yakho ukuze uthole amakhodi enkathazo ukuze uqiniseke.

5. Uwonga uphethiloli ophansi

Imitha yegesi ephansi ingolunye uphawu lwe-valve yokuhlanza i-canister embi. Umhwamuko kaphethiloli ongawusebenzisa imoto yakho ekushiseni ukhishwa ngesitsha se-EVAP. Esikhundleni sokungena ekamelweni elivuthayo, uphethiloli ushiswa ngaphambi kokuba ungene ohlelweni lokuvutha. Lokhu kusho ukuthi imoto yakho ngeke isebenzise uphethiloli ngendlela efanele futhi kunalokho izowuchitha.

I-canister purge solenoid iyingxenye ye-emission ngakho-ke iyingxenye ebalulekile ekuqinisekiseni ukuthi imoto ihlangabezana nezidingo zokungcola. Ivalvu yokuhlanza ivimbela ama-hydrocarbon anobuthi kuphethiloli ukuthi angavuzi epayipini lokukhipha umoya. Ngenxa yalesi sizathu, uma usola ukuthi i-canister purge solenoid yakho ingaba nenkinga, xhumana nochwepheshe bezokuxilongwa kwezimoto ukuze uthole ukuthi i-canister purge solenoid noma i-vacuum hose idinga ukushintshwa yini.
