Ungashintsha kanjani i-solenoid yokuvala i-EVP

Ivalvu ye-EGR iyadingeka ohlelweni lwe-EGR emotweni yakho. Ukuze le valve isebenze, i-solenoid yokuvala shaqa ye-EVP kufanele ilawule indawo nokusebenza kwayo.

Imboni yezimoto iye yahlangabezana nezikhathi zokungqubuzana, ikakhulukazi lapho izama ukuhlanganisa ubuchwepheshe besimanje ezingxenyeni ezindala. Isibonelo, ekuqaleni kwawo-1990 kuya maphakathi nawo-1991, abakhiqizi bezimoto abaningi baqala ukusuka ezinhlelweni ezilawulwa ngomshini baya kumakhompiyutha ngokugcwele kanye namasistimu alawulwa ngogesi. Isibonelo salokhu ukuthi amasistimu e-EGR aqhutshwa ngevacuum amadala ashintshwa kancane kancane aze agcine elawulwa ngokugcwele yikhompyutha. Lokhu kwakha uhlobo lwedizayini eyingxube yesistimu ye-EGR futhi izingxenye zadalwa ukuze kusheshiswe lokhu kuguqulwa. Enye yalezi zingxenye yaziwa ngokuthi i-EVP shutdown solenoid noma i-EGR valve position solenoid futhi yayisetshenziswa ezimotweni, emalolini nasezimotweni zeSUV ezithengiswa e-US kusukela ngo-2000 kuze kube ekuqaleni kwawo-XNUMX.

Eyethulwe ngo-1966 njengomzamo wokunciphisa ukukhishwa kwezimoto, uhlelo lwe-EGR lwenzelwe ukusabalalisa kabusha amagesi e-exhaust aqukethe uphethiloli ongashisiwe (noma ukukhishwa kwemoto) emuva kokuningi okuthathayo, lapho kushiswa khona inqubo yokuvutha. Ngokunikeza ama-molecule kaphethiloli angashisiwe ithuba lesibili lokusha, ukukhishwa kwezimoto eziphuma ohlelweni lwe-exhaust kuyancishiswa futhi ukonga kukaphethiloli ngokuvamile kuyathuthukiswa.

Amasistimu e-EGR okuqala asebenzisa isistimu yokulawula i-vacuum. Izimoto zesimanje, amaloli, nama-SUV asebenzisa ama-valve e-EGR alawulwa ngekhompiyutha aqukethe izinzwa eziningi nezilawuli ezivame ukuqapha isimo nokusebenza kohlelo lwe-EGR ukuze lusebenze kahle. Phakathi kwalokhu kuthuthukiswa okubili, izakhi ezihlukene zenziwe ukuze zenze umsebenzi ofanayo wokulinganisa nokuqapha ukusebenza kohlelo lwe-EGR. Kulolu hlelo lwesizukulwane sesibili, i-EVP shutdown solenoid noma i-EGR valve position solenoid ixhunywe ku-valve ye-EGR ngomugqa we-vacuum futhi ngokuvamile ifakwa ngokuhlukile ku-valve ye-EGR. Ngokuphambene, izinzwa zendawo zanamuhla ze-EVP zifakwe phezulu kwe-valve ye-EGR futhi zixhunywe kuzintambo zikagesi ezilawula futhi ezilawula ukusebenza kwayo.

Umsebenzi we-solenoid yokuvalwa kwe-EVP ukulawula ukugeleza kwe-valve ye-EGR. Idatha igadwa inzwa eyakhelwe ku-EVP solenoid yokuvala shaqa, edluliswa kumojula yokulawula injini yemoto (ECM) futhi isekelwe ipayipi le-vacuum elinamathiselwe kwiphampu ye-vacuum. Uma i-solenoid yokuvala shaqa iba ngcolile (imvamisa ngenxa yokunqwabelana kwekhabhoni eyeqile kuphethiloli ongashile ohlelweni lokukhipha umoya), inzwa ingase yehluleke noma ijame. Uma lokhu kwenzeka, kungaholela ekukhishweni kwezimoto eziningi ezingena egumbini elivuthayo, ekugcineni kudale isilinganiso esicebile sikaphethiloli womoya.

Uma uphethiloli ungeke ushise kahle, uphethiloli oweqile uyaphuma ku-exhaust yemoto, ngokuvamile okubangela ukuba imoto ingaphumeleli ekuhloleni ukukhishwa kwayo futhi kungalimaza injini nezinye izingxenye zemishini ngaphansi kwesivalo.

Ngokungafani nenzwa yendawo ye-EVP, i-solenoid yohambo lwe-EVP iwumshini ngokwemvelo. Ezimweni eziningi, i-solenoid spring iyanamathela futhi ingahlanzwa futhi ilungiswe ngaphandle kokufaka idivayisi. Kodwa-ke, le nqubo iyinkimbinkimbi ngendlela emangalisayo futhi kufanele yenziwe kuphela uchwepheshe oqinisekisiwe, njenge-AvtoTachki.

Kunenombolo yezimpawu eziyisixwayiso noma izimpawu zokuhluleka kwe-EVP ukuvala shaqa i-solenoid engaxwayisa umshayeli ngenkinga yale ngxenye. Ezinye zazo zihlanganisa okulandelayo:

• Isibani se-Check Engine siyakhanya. Uphawu lokuqala lwenkinga yemishini nge-EVP yokuvalwa kwe-solenoid ukukhanya kwe-Check Engine okuzayo.

Ikhodi evame ukuhlotshaniswa nenkinga yokunqanyulwa kwe-solenoid ye-EVP ithi P-0405. Nakuba ingalungiswa, kuyatuswa ukuthi kushintshwe le ngxenye noma wonke umzimba we-valve ye-EGR/EVP futhi usethe kabusha amakhodi ephutha ngesikena sokuxilonga ukuze usihlole.

• Imoto ihlulekile uhlolo lokukhishwa kwekhabhoni. Kwezinye izimo, ukwehluleka kwalesi sigaba kubangela i-valve ye-EGR ukuthi ifake uphethiloli ongashisiwe ekamelweni elivuthayo. Lokhu kuzoholela esilinganisweni esicebile sikaphethiloli womoya futhi kungase kubangele ukuhlolwa kokukhishwa kwekhabhoni kuhluleke.

• Kunzima ukuqala injini. I-solenoid ephukile noma eyonakele ye-EVP yokuvala shaqa ngokuvamile izophazamisa ukusebenza kokuqala, okuhlanganisa ukungenzi lutho, okungase futhi kubangele ukungenzi lutho, ukungafihli kahle, noma isivinini esiphansi senjini.

Ngenxa yendawo ekude, ama-solenoid amaningi okuvala i-EVP kulula kakhulu ukushintshwa. Le nqubo yenziwa lula yiqiniso lokuthi izimoto eziningi ezakhiwe ngeminyaka yawo-1990 nasekuqaleni kwawo-2000 zazingenazo izimbobo zezinjini eziningi noma ukuhlunga komoya okuyinkimbinkimbi futhi zisebenzisa imiklamo eminingi eyayizophazamisa indawo ye-solenoid.

• UkunakwaQaphela: Nakuba indawo ye-EVP yokuvala i-solenoid ngokuvamile ifinyeleleka kalula, umkhiqizi ngamunye uneziyalezo zakhe ezihlukile zokususa nokufaka esikhundleni sale ngxenye.
