Ungahlola kanjani i-USR
Okuqukethwe
Ukuhlola isistimu kwehla ekuboneni ukusebenza kwe-valve ye-EGR, inzwa yayo, kanye nezinye izingxenye zesistimu yokukhipha umoya we-crankcase (I-Exhaust Gas Recirculation). Ukuze uhlole, umshayeli uzodinga i-multimeter ye-electronic ekwazi ukusebenza kumodi ye-ohmmeter ne-voltmeter, ipompo ye-vacuum, isithwebuli sephutha se-ECU. impela kanjani ukuhlola isib kuzoncika engxenyeni ethile yesistimu. Ukuhlola okulula kakhulu kokusebenza kungaba ukulawula okubonakalayo okujwayelekile kokusebenza lapho amandla esetshenziswa kukho noma umoya ukhishwa.
Luyini uhlelo lwe-EGR
ukuze uqonde incazelo yokuhlolwa kwezempilo kwe-USR, kufanelekile ukugxila kafushane ngokuthi hlobo luni lwesistimu, kungani ludingeka nokuthi lusebenza kanjani. Ngakho-ke, umsebenzi wesistimu ye-EGR ukunciphisa izinga lokwakheka kwama-nitrogen oxides kumagesi aphumayo. Ifakwe kuzo zombili izinjini zikaphethiloli nezinjini zikadizili, ngaphandle kwalezo ezifakwe i-turbocharger (yize kukhona okuhlukile). Ukunciphisa ukukhiqizwa kwe-nitrogen oxides kufinyelelwa ngenxa yokuthi ingxenye yamagesi e-exhaust ibuyiselwa enjini yomlilo yangaphakathi ukuze ishise ngemuva. Ngenxa yalokhu, izinga lokushisa legumbi elivuthayo liyancipha, i-exhaust iba nobuthi obuncane, ukuqhunyiswa kuncipha njengoba kusetshenziswa isikhathi esiphezulu sokuthungela futhi ukusetshenziswa kukaphethiloli kuncipha.
Izinhlelo zokuqala ze-EGR zaziyi-pneumomechanical futhi zihambisana ne-EURO2 kanye ne-EURO3 amazinga emvelo. Ngokuqiniswa kwamazinga emvelo, cishe zonke izinhlelo ze-EGR seziphenduke i-elekthronikhi. Enye yezingxenye eziyisisekelo zesistimu i-valve ye-USR, ehlanganisa nenzwa elawula indawo ye-valve eshiwo. Iyunithi yokulawula ye-elekthronikhi ilawula ukusebenza kwe-valve ye-pneumatic isebenzisa i-electro-pneumatic valve yokulawula. ngakho-ke, ukuhlola i-USR kwehla ukuze kutholwe ukusebenza kwe-valve ye-USR, inzwa yayo, kanye nohlelo lokulawula (ECU).
Izimpawu zokuphuka
Kunenombolo yezimpawu zangaphandle ezikhombisa ukuthi kunenkinga ngesistimu, okuyinzwa ye-EGR. Kodwa-ke, izimpawu ezingezansi zingase zibonise okunye ukuwohloka kwenjini evuthayo yangaphakathi, ngakho-ke ukuxilongwa okwengeziwe kuyadingeka kokubili kwesistimu iyonke kanye ne-valve ikakhulukazi. Ngokuvamile, izimpawu ze-valve ye-EGR engasebenzi zizoba izimpawu ezilandelayo:
- Ukunciphisa amandla enjini evuthayo yangaphakathi nokulahlekelwa izici eziguquguqukayo zemoto. Okusho ukuthi, imoto "ayidonsi" lapho ishayela ikhuphuka futhi isesimweni esilayishiwe, futhi isheshisa kabi kusukela ekumeni.
- Ukusebenza okungazinzile kwenjini yomlilo yangaphakathi, isivinini "esintantayo", ikakhulukazi ekungenzini lutho. Uma injini isebenza ngesivinini esiphansi, ingase ime kungazelelwe.
- Izitolo ze-ICE ngemuva nje kokuqala. Kuvela lapho i-valve ivaleleke ivulekile futhi amagesi e-exhaust aya ekuthatheni ngokugcwele.
- Ukwenyuka kokusetshenziswa kukaphethiloli. Lokhu kubangelwa ukuncipha kwe-vacuum endaweni eningi yokuthatha, futhi ngenxa yalokho, ukuphinda kuthuthukiswe ingxube ye-air-fuel.
- Ukukhiqizwa kwephutha. Ngokuvamile, "injini yokuhlola" isibani esiyisixwayiso sisebenza kudeshibhodi, futhi ngemva kokwenza ukuxilongwa ngamadivayisi wokuskena, ungathola amaphutha ahlobene nokusebenza kwesistimu ye-USR, isibonelo, iphutha p0404, p0401, p1406 nabanye.
Uma kubonakala okungenani eyodwa yezimpawu ezisohlwini, kufanelekile ukuxilonga ngokushesha usebenzisa isithwebuli sephutha, kuzoqinisekisa ukuthi inkinga iku-valve ye-USR. Ngokwesibonelo, Skena Ithuluzi Pro Black Edition yenza kube nokwenzeka ukufunda amaphutha, ukubuka ukusebenza kwezinzwa ezihlukahlukene ngesikhathi sangempela futhi ulungise ngisho nemingcele ethile.
Ngalesi sithwebuli, ungabona ukuthi i-valve ye-solenoid yesilawuli se-vacuum isebenza kanjani (imininingwane ekugcineni kwesihloko). Ukuba nedivayisi enjalo, ungathola ngokushesha imbangela futhi uqale ukuyiqeda. Ukuhlola i-valve egaraji kulula kakhulu.
Izimbangela zokungasebenzi kahle kohlelo lwe-EGR
Kunezimbangela ezimbili kuphela eziyisisekelo zokungasebenzi kahle kwe-valve ye-USR kanye nohlelo lulonke - amagesi amancane kakhulu aphumayo adlula ohlelweni futhi amagesi akhipha umoya amaningi adlula ohlelweni. Ngakolunye uhlangothi, izizathu zalokhu kungaba yizimo ezilandelayo:
- Ku-EGR valve stem kwakheka umule. Lokhu kwenzeka ngenxa yezizathu zemvelo. Njengoba kushiwo ngenhla, amagesi e-exhaust adlula kuwo, futhi umsizi uhlala ezindongeni ze-valve, kuhlanganise nesiqu. Lesi simo siba sibi nakakhulu ezimweni lapho umshini usebenza ezimeni ezinolaka. okungukuthi, ngokuguga kwenjini evuthayo yangaphakathi, ukwanda kwenani lamagesi e-crankcase, ukusetshenziswa kukaphethiloli wekhwalithi ephansi. Ngemuva kokuhlonza i-valve, kuhlale kunconywa ukuhlanza isiqu nge-carb cleaner noma isicoci sokuhlanza esifanayo. Ngokuvamile, amanye ama-solvents (isibonelo, umoya omhlophe) noma i-acetone ehlanzekile ehlanzekile isetshenziselwa lokhu. ungasebenzisa futhi uphethiloli noma udizili.
- Ukuvuza kwe-diaphragm I-valve ye-EGR. Lokhu kuphuka kuholela eqinisweni lokuthi i-valve eshiwo ayivuli ngokugcwele futhi ayivali, okungukuthi, amagesi aphumayo avuza kuwo, okuholela emiphumeleni echazwe ngenhla.
- Iziteshi zohlelo lwe-EGR ziphekwe. Lokhu kuphinde kubangele ukuthi amagesi akhipha umoya nomoya kungashaywe kuwo ngokujwayelekile. Ukupheka kwenzeka ngenxa yokuvela kwe-soot ezindongeni ze-valve kanye / noma iziteshi lapho amagesi okukhipha umoya adlula khona.
- Isistimu ye-EGR ivalwe kahle ngokungalungile. Abanye abanikazi bezimoto abavame ukuhlangabezana neqiniso lokuthi ngenxa yokusetshenziswa kwesistimu ekhethiwe ye-ICE ilahlekelwa amandla, bavele bacime i-valve ye-EGR. Kodwa-ke, uma isinqumo esinjalo senziwe, khona-ke lokhu kufanele kwenziwe ngendlela efanele, ngaphandle kwalokho imitha yesisindo somoya izothola ulwazi lokuthi kwenzekani ukugeleza komoya okukhulu kakhulu. Lokhu kuyiqiniso ikakhulukazi lapho uthenga imoto esetshenzisiwe, lapho umnikazi omusha engazi ukuthi i-valve ye-EGR ixhunyiwe emotweni. Uma imoto ifakwe ohlelweni olunjalo, kuhle ukubuza umnikazi wemoto wangaphambili mayelana nesimo sayo, futhi ubuze ukuthi ngabe uhlelo lwe-USR lwalugcwele ngokuphelele.
- Ivalve ye-EGR ebambekile ngesikhathi sokuvalwa kanye/noma ukuvulwa kwayo. Kunezinketho ezimbili lapha. Eyokuqala inzwa ngokwayo inephutha, engakwazi ukudlulisa idatha elungile kuyunithi yokulawula ye-elekthronikhi. Okwesibili izinkinga nge-valve ngokwayo. Kuphakathi kokuthi ayivuleki ngokuphelele noma ayivaleki ngokuphelele. Lokhu kuvame ukubangelwa inani elikhulu le-soot kuwo, elakhiwe ngenxa yokushiswa kukaphethiloli.
- I-valve ye-EGR i-jerky. I-solenoid esebenzayo kufanele inikeze ukuhlehla okushelelayo kwesiqu, futhi ngokufanelekile, inzwa kufanele ithwebule idatha eshintsha ngokushelelayo ekumeni kwe-damper. Uma uguquko lwenzeka kungazelelwe, khona-ke imininingwane ehambisanayo idluliselwa kukhompyutha, futhi uhlelo ngokwalo alusebenzi kahle ngemiphumela echazwe ngenhla yenjini yangaphakathi yomlilo.
- Kulezo zimoto lapho ukunyakaza kwama-valve kunikezwa khona i-stepper drive, izizathu ezingenzeka zilele kuyo ngokuqondile. okungukuthi, injini kagesi ingase yehluleke (isibonelo, i-short-circuit i-winding, ihluleke ukuthwala), noma igiya lokushayela lingase lihluleke (izinyo elilodwa noma ngaphezulu kuwo liyaphuka noma liguge ngokuphelele).
Ukuhlolwa kwesistimu ye-USR
Ngokwemvelo, ekwenziweni okuhlukile kanye namamodeli ezimoto, indawo yenzwa ye-EGR izohluka, noma kunjalo, noma ngabe kungenzeka, lo mhlangano uzobe useduze nenani eliningi. Kancane kancane, itholakala kupheshana lokumunca noma ku-throttle block.
Ezimweni zegaraji, isheke kufanele liqale ngokuhlola okubukwayo. Ngokuvamile, kunezindlela ezimbili zokuxilonga i-valve ye-EGR - ngokuyidiliza nangaphandle kwayo. Kodwa-ke, kusengcono ukwenza isheke elinemininingwane eyengeziwe ngokudilizwa komhlangano, ngoba ngemuva kwesheke, uma i-valve ivalwe ngamadiphozithi kaphethiloli oshisiwe, ingahlanzwa ngaphambi kokufakwa kabusha. Okokuqala, sizocubungula izindlela zokuhlola ngaphandle kokudiliza izingxenye ngazinye.
Ungahlola kanjani ukusebenza kwe-EGR
Ngaphambi kokwenza isheke eligcwele, udinga ukuqiniseka ukuthi i-valve isebenza nhlobo. Ukuhlolwa okunjalo kwenziwa ekuqaleni.
Uma kudingekile ukuhlola ukusebenza kwe-valve ye-pneumatic, kwanele ukubona ukushaywa kwesiqu ngesikhathi sokudlula kwegesi (umuntu oyedwa ovuselelayo, owesibili ubukeka). Noma ngokucindezela ulwelwesi - ijubane kufanele lihlehle. ukuze uhlole i-valve ye-solenoid ye-EGR, udinga ukusebenzisa amandla ngokuqondile ukusuka kubhethri ukuya ekuhlanganiseni nasekususeni kwesixhumi, kuyilapho ulalele noma yikuphi ukuchofoza. Ngemva kokwenza lezi zinyathelo, ungaqhubekela ekuhloleni okuningiliziwe kwe-EGR.
Ukucindezela i-valve
Njengoba injini yomlilo yangaphakathi isebenza ngokungenzi lutho, udinga ukucindezela kancane kulwelwesi. Ngokuya ngesakhiwo esithile se-valve, ingatholakala ezindaweni ezihlukahlukene. Isibonelo, emotweni edumile i-Daewoo Lanos, udinga ukucindezela ngaphansi kwepuleti, ngaphansi kwayo kukhona ama-cutouts emzimbeni, ongacindezela ngawo ulwelwesi. Okusho ukuthi, ukucindezela akwenzeki kulwelwesi ngokwalo, ngoba livikelwe ngumzimba, kodwa kuleyo ngxenye yomzimba etholakala ngenhla kwayo.
Uma, ngesikhathi sokucindezela i-node eshiwo, isivinini senjini sacwiliswa futhi saqala "ukuminyanisa" (ijubane laqala ukuwa), lokhu kusho ukuthi isihlalo se-valve sisesimweni esihle, futhi ngokuvamile, akukho lutho oludingekayo. ukulungiswa, ngaphandle kwezinhloso zokuvimbela (ukwenza lokhu, kuzodingeka ukuqaqa i-valve ye-EGR futhi ngokuhambisanayo kwenziwe ukuxilongwa okwengeziwe okuyinkimbinkimbi kweyunithi). Kodwa-ke, uma kungenzeki lutho ngemuva kokucindezela okucacisiwe, futhi injini yomlilo yangaphakathi ayilahlekelwa isivinini, lokhu kusho ukuthi ulwelwesi alusaqinile, okungukuthi, uhlelo lwe-EGR alusebenzi. Ngakho-ke, kuyadingeka ukudiliza i-valve ye-USR futhi wenze ukuxilonga okwengeziwe kwesimo se-valve ngokwayo kanye nezinye izakhi zesistimu.
Hlola i-valve
Njengoba kushiwo ngenhla, indawo ye-valve ingase ihluke ezimotweni ezahlukene, noma kunjalo, ngokuvamile ifakwe endaweni eningi yokungenisa. Isibonelo, emotweni ye-Ford Escape 3.0 V6, ifakwe epayipini lensimbi eliphuma ku-multifold intake. I-valve ivuleka ngenxa ye-vacuum evela ku-solenoid. Isibonelo sokuqinisekisa okwengeziwe sizonikezwa ngokuqondile enjinini evuthayo yangaphakathi yemoto eshiwo.
Ukuze uhlole ukusebenza kahle kwe-valve ye-EGR, kwanele ukunqamula i-hose ku-valve ngesivinini esingenzi lutho senjini evuthayo yangaphakathi, lapho i-vacuum (i-vacuum) inikezwa ngayo. Uma kukhona ipompo ye-vacuum ekufinyeleleni okujwayelekile, khona-ke ungayixhuma emgodini we-valve bese udala i-vacuum. Uma i-valve isebenza, injini yomlilo yangaphakathi izoqala "ukuminyanisa" futhi inyakaze, okungukuthi, ijubane layo lizoqala ukuwa. Esikhundleni sepompo ye-vacuum, ungavele uxhume enye ipayipi bese udala i-vacuum ngokumunca umoya ngomlomo wakho. Imiphumela kufanele ifane. Uma injini yomlilo yangaphakathi iqhubeka nokusebenza ngokujwayelekile, khona-ke i-valve cishe inephutha. Kutuswa ukuyihlakaza ukuze kwenziwe ukuxilongwa okuningiliziwe. Noma ngabe yikuphi, ukulungiswa kwayo okwengeziwe kuyodingeka kwenziwe hhayi esihlalweni sayo, kodwa ngaphansi kwezimo zesitolo sokulungisa izimoto (igalaji).
Hlola i-solenoid
I-solenoid iwukumelana nogesi okuvumela ukugeleza kwamanje kuwo. I-solenoid ishintsha i-voltage edlula kuyo isebenzisa i-pulse-width modulation (PWM). I-voltage iyashintsha ngesikhathi sokusebenza, futhi lokhu kuwuphawu lokusebenzisa i-vacuum ku-valve ye-EGR. Into yokuqala okufanele uyenze lapho uhlola i-solenoid ukuqinisekisa ukuthi i-vacuum ine-vacuum enhle ngokwanele. Sinikeza isibonelo sokuqinisekiswa kwemoto efanayo ye-Ford Escape 3.0 V6.
Into yokuqala okufanele uyenze ukunqamula amashubhu amancane phansi kwe-solenoid, emva kwalokho udinga ukuqala injini yomlilo yangaphakathi. Sicela uqaphele ukuthi amashubhu kufanele asuswe ngokucophelela ukuze angaphuli izixhumi ezilingana kuzo! Uma i-vacuum kwelinye lamashubhu ihlelekile, khona-ke izozwakala, ezimweni ezimbi kakhulu, ungafaka umunwe wakho ku-tube. Uma kungekho vacuum, ukuhlolwa okwengeziwe kuyadingeka. Ukwenza lokhu, kuyodingeka futhi ukuthi kuqhutshekwe nokuqaqa i-valve ye-USR esihlalweni sayo ukuze kuhlolwe kabanzi.
Ngemuva kwalokho, kuyadingeka ukuhlola ingxenye kagesi, okungukuthi, kuyadingeka ukuhlola ukunikezwa kwamandla we-solenoid. Ukuze wenze lokhu, udinga ukukhipha i-chip entweni eshiwo. Kunezintambo ezintathu - isignali, amandla kanye nomhlabathi. Usebenzisa i-multimeter eshintshelwe kumodi yokulinganisa i-voltage ye-DC, udinga ukuhlola amandla. Lapha i-probe eyodwa ye-multimeter ibekwe kothintana naye wokuhlinzeka, okwesibili - emhlabathini. Uma kukhona amandla, i-multimeter izobonisa inani le-voltage yokuhlinzeka cishe ngama-volts angu-12. Ngesikhathi esifanayo, kufanelekile ukuhlola ubuqotho bocingo lwe-impulse. Lokhu kungenziwa futhi kusetshenziswa i-multimeter, kodwa kushintshelwe kumodi "yokudayela". Kwi-Ford Escape 3.0 V6 eshiwo ine-insulation ensomi, kanti okokufaka kwe-ECU inenombolo engu-47 kanye nokufakwa okunsomi. Ngokufanelekile, zonke izintambo kufanele zibe sesimweni esikahle futhi zibe nokufakwa okuqinile. Uma izintambo ziphukile, kufanele zishintshwe ezintsha. Uma i-insulation yonakalisiwe, ungazama ukuyifaka nge-tape kagesi noma i-heat shrink tape. Nokho, le nketho ifaneleka kuphela uma umonakalo umncane.
Ngemuva kwalokho, udinga ukuhlola ubuqotho bezintambo ze-solenoid ngokwayo. Ukuze wenze lokhu, ungashintsha i-multimeter kumodi yokuqhubeka noma ulinganise ukumelana kukagesi. bese, ngama-probes amabili, ngokulandelana, xhuma emiphumeleni emibili yezintambo ze-solenoid. Inani lokumelana lamadivayisi ahlukene lingase lihluke, kodwa Yiba noma kunjalo, kufanele lihluke ku-zero kanye nokungapheli. Uma kungenjalo, kukhona isifunda esifushane noma ikhefu elijikayo, ngokulandelanayo.
Ihlola inzwa ye-EGR
Umsebenzi we-sensor ukurekhoda umehluko wengcindezi kwelinye nelinye ingxenye ye-valve, ngokulandelana, ivele idlulisele ulwazi kukhompyutha mayelana nesimo se-valve - ivuliwe noma ivaliwe. Okokuqala, udinga ukuhlola ubukhona bamandla kuwo.
Shintsha i-multimeter ibe imodi yokulinganisa i-voltage ye-DC. Xhuma enye yama-probe ukuze uxhume intambo engu-3 kunzwa, bese uphenyo lwesibili lube phansi. ngokulandelayo udinga ukuqala injini. Uma konke kujwayelekile, i-voltage phakathi kwama-probe amabili abonisiwe kufanele ilingane nama-volts angu-5.
Okulandelayo udinga ukuhlola i-voltage ocingweni lwe-impulse No. Esimweni lapho injini evuthayo yangaphakathi ingafudunyezwanga (uhlelo lwe-EGR alusebenzi), i-voltage kuyo kufanele ibe ngu-1 Volts. Ungayikala ngendlela efanayo nentambo yamandla. Uma ipompo ye-vacuum itholakala, khona-ke i-vacuum ingasetshenziswa ku-valve. Uma inzwa isebenza, futhi izolungisa leli qiniso, khona-ke i-voltage ephumayo ocingweni lwe-impulse izokhula kancane kancane. Ku-voltage engaba ngu-0,9 volts, i-valve kufanele ivule. Uma ngesikhathi sokuhlolwa i-voltage ingaguquki noma ishintshe ngokungaqondile, ngakho-ke, cishe, inzwa ayisebenzi futhi kuyadingeka ukwenza ukuxilongwa kwayo okwengeziwe.
Uma imoto igxilile ngemuva kokusebenza kwenjini emfishane, ungaqaqa ivalve ye-USR uyincike bese uyisusa futhi ukuze ubheke ukusabela kwenjini evuthayo yangaphakathi - uma ukhipha i-valve ku-crankcase, kuphuma intuthu eningi. futhi injini yomlilo yangaphakathi iqala ukusebenza ngokulinganayo, uhlelo lokungenisa umoya noma i-valve ngokwayo inephutha. Ukuhlolwa okwengeziwe kuyadingeka lapha.
Ukudilizwa ukuhlolwa
Kungcono ukuhlola i-valve ye-EGR uma ikhishwa. Lokhu kuzokwenza kube nokwenzeka ukuba kubonakale futhi ngosizo izinsimbi ukuhlola isimo salo. Into yokuqala okufanele uyenze ukuhlola ukuthi iyasebenza yini. Eqinisweni, i-valve iyi-solenoid (ikhoyili), okumele ihlinzekwe ngama-volts angu-12 wamanje oqondile, njengakumjikelezo kagesi wemoto.
Sicela uqaphele ukuthi ukuklama kwama-valve kungase kuhluke, futhi ngokufanelekile, izinombolo zothintana nabo okudingeka zinikezwe amandla nazo zizohluka, ngokulandelana, asikho isisombululo sendawo yonke lapha. Isibonelo, emotweni yeVolkswagen Golf 4 APE 1,4, kunezikhonkwane ezintathu kuvalvu ezinezinombolo 2; ezine; 4. Amandla kagesi kufanele asetshenziswe kumatheminali anomboro 6 no-2.
Kuyatuseka ukuthi ube nomthombo we-voltage we-AC esandleni, ngoba ekusebenzeni (emotweni) i-voltage yokulawula iyahlukahluka. Ngakho, esimweni esivamile, i-valve iqala ukuvula ngama-volts angu-10. Uma ususa ama-volts angu-12, khona-ke izovala ngokuzenzakalelayo (isiqu sizongena ngaphakathi). Ngokuhambisana nalokhu, kufanelekile ukuhlola ukumelana kukagesi kwenzwa (potentiometer). Ngenzwa yokusebenza ku-valve evulekile, ukumelana phakathi kwezikhonkwane 2 no-6 kufanele kube mayelana ne-4 kOhm, futhi phakathi kuka-4 no-6 - 1,7 kOhm. Esimweni esivaliwe se-valve, ukumelana okuhambisanayo phakathi kwezikhonkwane 2 no-6 kuzoba ngu-1,4 kOhm, futhi phakathi kuka-4 no-6 - 3,2 kOhm. Kwezinye izimoto, kunjalo, amanani azohluka, kodwa ingqondo izohlala ifana.
Kanye nokuhlola ukusebenza kwe-solenoid, kufanelekile ukuhlola isimo sobuchwepheshe se-valve. Njengoba kushiwo ngenhla, i-soot (imikhiqizo yokushiswa kukaphethiloli) iqoqa ebusweni bayo ngokuhamba kwesikhathi, ihlezi ezindongeni zayo naphezu kwenduku. Ngenxa yalokhu, ukunyakaza okushelelayo kwe-valve nesiqu kungase kuphazamiseke. Ngisho noma ungekho umule omningi lapho, kusanconywa ngezinhloso zokuvimbela ukuwuhlanza ngaphakathi nangaphandle ngokuhlanza.
Ukuqinisekiswa kwesoftware
Enye yezindlela eziphelele nezilula zokuxilonga uhlelo lwe-EGR ukusebenzisa isofthiwe efakwe kukhompuyutha ephathekayo (ithebhulethi noma enye igajethi). Ngakho-ke, ezimotweni ezikhiqizwa ukukhathazeka kwe-VAG, enye yezinhlelo ezidume kakhulu zokuxilonga i-VCDS noma ngesiRashiya - "Vasya Diagnostic". Ake sibheke ngokushesha i-algorithm yokuhlola ye-EGR ngale softhiwe.
Hlola i-EGR kuhlelo lwe-Vasya Diagnost
Isinyathelo sokuqala ukuxhuma ikhompuyutha ephathekayo kuyunithi yokulawula kagesi ye-ICE bese uqhuba uhlelo olufanele. lapho-ke udinga ukufaka iqembu elibizwa nge-"ICE Electronics" kanye nemenyu ethi "Custom Groups". Phakathi kwezinye, ezansi kakhulu ohlwini lweziteshi, kuneziteshi ezimbili ezinenombolo engu-343 no-344. Eyokuqala ibizwa ngokuthi “I-EGR Vacuum Regulator Solenoid Valve; actuation" kanti eyesibili "EGR Solenoid Valve; inani langempela".
Eqinisweni, lokhu kusho ukuthi ngokusho kwesiteshi 343, umuntu angahlulela ukuthi yiliphi inani elilinganiselwe i-ECU enquma ukuvula noma ukuvala i-valve ye-EGR ngombono. Futhi isiteshi 344 sibonisa ukuthi yimaphi amanani angempela esebenza ngawo i-valve. Ngokufanelekile, umehluko phakathi kwalezi zinkomba ku-dynamics kufanele ube mncane. Ngakho, uma kukhona umehluko omkhulu phakathi kwamanani eziteshini ezimbili ezikhonjisiwe, khona-ke i-valve ayisebenzi ngokwengxenye. Futhi umehluko omkhulu ekufundweni okuhambisanayo, i-valve yonakaliswa kakhulu. Izizathu zalokhu ziyafana - i-valve engcolile, i-membrane ayibambi, njalonjalo. Ngokuvumelana nalokho, usebenzisa amathuluzi esoftware, kungenzeka ukuhlola isimo se-valve ye-EGR ngaphandle kokuyidiliza esihlalweni sayo enjinini yangaphakathi evuthayo.
isiphetho
Ukuhlola uhlelo lwe-EGR akunzima kakhulu, futhi ngisho nomshayeli we-novice angakwenza. Uma i-valve ihluleka ngesizathu esithile, into yokuqala okufanele uyenze ukuskena inkumbulo ye-ECU ngamaphutha. kuyalulekwa futhi ukuyihlakaza nokuyihlanza. Uma inzwa ingasebenzi, ayilungiswa, kodwa ifakwe entsha.
