Idatha ye-OBD-II DTC

Ukulungisa uphethiloli wesilinda 5 kumkhawulo omncane

Kusho ukuthini lokhu?

Le yikhodi yezinkinga zokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu kuzo zonke izimoto zikaphethiloli ze-OBD-II. Lokhu kungafaka kodwa kungagcini eMazda, Land Rover, Jaguar, Subaru, Ford, BMW, Dodge, njll. Naphezu kobujamo obujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokulungiswa. .

Ikhodi ye-P02AB egciniwe isho ukuthi imodyuli yokulawula i-powertrain (PCM) ithole isimo senhlanganisela esicebile ngokweqile kusilinda esithile enjinini, kulokhu isilinda # 5.

I-PCM isebenzisa uhlelo lokunquma uphethiloli ukwandisa noma ukunciphisa ukulethwa kukaphethiloli njengoba kudingeka. Okokufaka inzwa yomoya-mpilo kunikeza i-PCM idatha eyidingayo ukulungisa isiqu sikaphethiloli. I-PCM isebenzisa ukuhlukahluka kwe-fuel injector pulse wide modulation (PWM) ukushintsha isilinganiso somoya / sephethiloli.

I-PCM ibala ngokuqhubekayo itrimu yesikhashana kaphethiloli. Ishintshashintsha ngokushesha futhi ingesinye sezici ezibalulekile ekubaleni ukulungiswa kwephethiloli kwesikhathi eside. Imoto ngayinye inamaphesenti amancane futhi aphezulu kakhulu we-fuel trim afakwe ku-PCM. Amapharamitha we-short term petrim trim abanzi kakhulu kunezincazelo zepharamitha ye-fuel trim yesikhathi eside.

Ukuphambuka okuncane kukhuni kukaphethiloli, okuvame ukukalwa ngamaphesenti avumayo noma amabi, kuvamile futhi ngeke kuholele ekutheni kugcinwe ikhodi engu-P02AB. Izilungiselelo zokunquma kukaphethiloli (ezikahle noma ezingezinhle) zivame ukuba sebangeni lamaphesenti angamashumi amabili nanhlanu. Uma lo mkhawulo omkhulu wedluliwe, lolu hlobo lwekhodi luzolondolozwa.

Lapho injini isebenza kahle futhi asikho isidingo sokwengeza noma ukwehlisa inani likaphethiloli elinikezwe isilinda ngasinye, ukulungiswa kokusetshenziswa kukaphethiloli kufanele kubonise phakathi kukaziro no-XNUMX%. Lapho i-PCM ithola isimo sokukhipha okunciphile, kuyadingeka ukukhulisa ukulethwa kukaphethiloli nokulungiswa kokusebenzisa uphethiloli kuzobonisa iphesenti elihle. Uma ukuqeda kucebe kakhulu, injini idinga uphethiloli omncane futhi ukulungiswa kokusetshenziswa kukaphethiloli kufanele kubonise iphesenti elibi.

Bheka Futhi: Konke Ofuna Ukukwazi Ngama-Fuel Trims.

Izimoto ze-OBD-II zizodinga ukusungula iphethini yecebo lesikhathi eside likaphethiloli, elizodinga imijikelezo eminingi yokushisa.

Amagrafu ama-Fuel Trim aboniswe yi-OBD-II:

Buyini ubunzima bale DTC?

I-P02AB kufanele ibekwe njengosindayo njengoba uphethiloli ocebile ungaholela ezinkingeni eziningi zokushayela kanye nomonakalo kwisiguquli se-catalytic.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P02AB zingafaka:

• Ukunciphisa ukusebenza kwenjini
• Ukunciphisa ukusebenza kwephethiloli
• Ukubambezeleka kwenjini
• Ubukhona Bamakhodi Okukhipha Okugcwele Asindisiwe
• Amakhodi wokugculisa nawo angagcinwa

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yokunquma kaphethiloli ye-P02AB zingafaka:

• Umjovo wephethiloli onamaphutha
• Isilawuli sengcindezi esibi
• Inzwa ye-oxygen engaphelele
• Ukungasebenzi kahle kwenzwa yokugeleza komoya (MAF) noma inzwa yomfutho womoya omningi (MAP)

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P02AB?

Uma kunamakhodi ahlobene ne-MAF noma i-MAP, wuhlolisise bese uwalungisa ngaphambi kokuzama ukuthola le khodi ye-P02AB.

Ngingaqala ukuxilongwa ngokuhlolwa okujwayelekile kwendawo yesitimela kaphethiloli. Ukugxila kwami ​​kuzoba kumlawuli wengcindezi kaphethiloli kanye nomthombo wokuvula wesilawuli sengcindezi kaphethiloli (uma sikhona). Ngangibheka umlawuli ukuthi akukho yini okuvuzayo. Uma kukhona igesi ngaphakathi noma ngaphandle komlawuli, sola ukuthi ayisebenzi.

Uma kungekho zinkinga zomshini ezisobala egumbini lenjini, kuzodingeka amathuluzi amaningana ukuqhubeka nokuxilongwa:

1. Isithwebuli sokuhlola
2. I-Digital Volt / Ohmmeter (i-DVOM)
3. I-gauge yengcindezi ye-Fuel ene-adapters
4. Umthombo onokwethenjelwa wolwazi lwemoto

Ngemuva kwalokho ngangiyoxhuma isithwebuli ethekwini lokuhlonza imoto. Ngibuyise wonke amakhodi agciniwe futhi ngafriza idatha yohlaka ngabe sengikubhala konke ukuze kusetshenziswe esikhathini esizayo. Manje sengizosula amakhodi bese ngihlola ukushayela imoto ukubona ukuthi akhona asethwe kabusha yini.

Finyelela ukusakazwa kwedatha yesithwebuli futhi ubone ukusebenza kwenzwa yomoya-mpilo ukuze ubone ukuthi ngabe isimo sokukhipha okunothile sikhona ngempela. Ngithanda ukunciphisa ukusakazwa kwedatha ukufaka kuphela idatha efanelekile. Lokhu kunikeza izikhathi zokuphendula idatha ngokushesha nokufundwa okunembe kakhudlwana.

Uma ngabe isimo sokukhipha ngokweqile sikhona:

Isinyathelo 1

Sebenzisa igeji yokucindezela ukuhlola umfutho kaphethiloli bese uyiqhathanisa nedatha yomkhiqizi. Uma ingcindezi kaphethiloli ingaphakathi kokucacisiwe, iya esinyathelweni 2. Uma ingcindezi kaphethiloli iphakeme kunaleyo ebekiwe, sebenzisa i-DVOM ukuhlola amasekethe olawulo lokucindezelwa kukaphethiloli kanye nomlawuli uqobo (uma kuwugesi). Nqamula zonke izilawuli ezihlobene kusuka kusifunda ngaphambi kokusebenzisa i-DVOM ukuhlola ukumelana kanye / noma ukuqhubeka ne-DVOM. Ukwehluleka ukunqamula isilawuli kungasilimaza.

Lungisa noma shintsha amasekethe wesistimu noma izingxenye ezingahlangabezani nezincazelo zomkhiqizi. Uma isilawuli sengcindezi kaphethiloli siqhutshwa yisijini senjini, kufanele sithathelwe indawo uma ingcindezi kaphethiloli iphezulu kakhulu.

Isinyathelo 2

Finyelela kusixhumi se-injector (se-injector okukhulunywa ngaso) bese usebenzisa i-DVOM (noma isibani se-noid uma sikhona) ukuhlola amandla we-injector kanye ne-pulse yomhlabathi (owokugcina we-PCM). Uma kungatholwa ukushaya kwenhlabathi kusixhumi se-injector, noma uma umhlabathi unomphela (injini isebenza), yiya esinyathelweni sesi-3.

Uma amandla we-voltage nomhlabathi ekhona, xhuma kabusha i-injector, sebenzisa i-stethoscope (noma enye into elalelayo) bese ulalela ngenjini esebenza. Umsindo ozwakalayo wokuchofoza kufanele uphindwe ngezikhathi ezithile. Uma kungekho msindo noma kuphakathi nendawo, sola ukuthi umjovo wesilinda ohambisanayo awusasebenzi noma uvalekile. Noma isiphi isimo kungenzeka sidinge ukufaka esikhundleni somjovo.

Isinyathelo 3

Iningi lezinhlelo zesimanje zokujova uphethiloli zinikezela ngokutholakala njalo kwamandla kagesi ebhethri ku-injector ngayinye kaphethiloli, ne-PCM iletha ukushaya kwenhlabathi ngesikhathi esifanele ukuvala isekethe futhi kudale ukuthi uphethiloli ufuthwe kwisilinda. Sebenzisa i-DVOM ukuhlola ukudonsa ngomjovo kusixhumi se-PCM. Uma kungekho mgomo (noma umhlabathi onomphela) wokuxhuma kusixhumi se-PCM, futhi awekho amanye amakhodi akhona, sola i-PCM enephutha noma iphutha lohlelo lwe-PCM.

Qaphela. Sebenzisa ukuqaphela lapho uhlola / ushintsha izingxenye zezinto ezisebenzisa umfutho ophakeme.
