I-vacuum ephansi kakhulu ohlelweni lwe-braking oluphuthumayo

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Ezijwayelekile Yokuxilonga (i-DTC) isetshenziswa kakhulu ezimotweni eziningi ze-OBD-II. Lokhu kungafaka, kepha akukhawulelwe ku, Chevrolet, Ford, VW, Buick, Cadillac, njll.

Ikhodi egcinwe i-P050F isho ukuthi i-powertrain control module (PCM) ithole okokufaka kusuka ku-vacuum brake sensor (VBS) ekhombisa ukunganele kwebhuleki booster vacuum.

Ngenkathi kunezinhlobo ezahlukahlukene ezahlukahlukene (kufaka phakathi i-hydraulic ne-elektroniki) yezinhlelo zokubopha ezisizayo, le khodi isebenza kuphela kulabo abasebenzisa i-injini vacuum ne-servo brake booster.

I-vacuum brake booster itholakala phakathi kwe-brake pedal kanye ne-master cylinder. Iboshelwe ku-bulkhead (imvamisa phambi kwesihlalo somshayeli). Ingafinyelelwa nge-hood evulekile. Omunye umkhawulo wokuxhuma kwe-booster uphumela phakathi kwe-bulkhead bese unamathela engalweni ye-brake pedal. Olunye uhlangothi lwentonga ye-actuator luphusha i-master cylinder piston, edudula uketshezi lwamabhuleki emigqeni yamabhuleki futhi iqalise ukubhuleka kwesondo ngalinye.

I-booster booster iqukethe umzimba wensimbi onamapheya amakhulu wokuhlanza ngaphakathi. Lolu hlobo lwe-booster lubizwa nge-double diaphragm vacuum brake booster. Kukhona ezinye izimoto ezisebenzisa i-diaphragm amplifier eyodwa, kepha lokhu akuvamile. Lapho injini isebenza, kufakwa i-diaphragm i-vacuum engaguquki, edonsa kancane isigwedlo se-brake pedal. I-valve yokuhlola eya endaweni eyodwa (ku-hose vacuum) ivimbela ukulahleka komshini lapho injini ingaphansi komthwalo.

Ngenkathi izimoto eziningi zikadizili zisebenzisa i-hydraulic booster system, ezinye zisebenzisa i-vacuum brake booster. Njengoba izinjini zikadizili zingakhi i-vacuum, kusetshenziswa ipompo eliqhutshwa ibhande njengomthombo we-vacuum. Olunye uhlelo lwe-vacuum booster lusebenza ngendlela efanayo nohlelo lwenjini yegesi. 

Ukulungiswa okujwayelekile kwe-VBS kufaka phakathi ukumelana nokuzwela kwengcindezi ngaphakathi kwesifudlana esincane se-vacuum esifakwe kupulasitiki ovaliwe. Ukucindezela komshini (ukuminyana komoya) kukalwa ngama-kilopascals (kPa) noma ngamasentimitha e-mercury (Hg). I-VBS ifakwa nge-grommet ewugqinsi yenjoloba ezindlini zamabhuleki e-servo. Njengoba ingcindezi yomshini ikhula, ukumelana neVBS kuyehla. Lokhu kwandisa amandla wesifunda we-VBS. Lapho ingcindezi yomshini incipha, kwenzeka umphumela ohlukile. I-PCM ithola lezi zinguquko zamandla kagesi njengoba ingcindezi ye-servo ishintsha futhi iphendula ngokufanele.

Uma i-PCM ithola ileveli yokuphumula yamabhuleki ngaphandle kwepharamitha ebekiwe, kuzogcinwa ikhodi ye-P050F futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa.

Isithombe senzwa yengcindezi (yokuphumula) ye-brake booster / VBS:

Buyini ubunzima bale DTC?

Ukucindezela okuphansi kwe-vacuum booster kungakhuphula inani lamandla adingekayo ukuze kusebenze ukubopha. Lokhu kungaholela ekushayisaneni nemoto. Inkinga P050F kumele ilungiswe ngokushesha.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenjini engu-P050F zingafaka:

• Ukuhayizwa kuzwakala lapho iphedali yebhuleki icindezelekile
• Kudingeka umzamo owengeziwe wokucindezela isisekelo sebhuleki
• Amanye amakhodi angagcinwa, kufaka phakathi amakhodi we-Manifold Absolute Pressure (MAP).
• Izinkinga ngokuphathwa kwezinjini ezibangelwa ukuvuza komshini

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Ukuvuza kwangaphakathi ku-vacuum brake booster
• Isivalo sebhuleki esingalungile
• Ipayipi le-vacuum eliqhekekile noma elinqanyuliwe
• I-valve yokuhlola engabuyisi ku-hose yokuhlinzeka nge-vacuum ayisebenzi.
• Umshini onganele enjini

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P050F?

Okokuqala, uma kuzwakala umsindo wokuhayiza lapho ucindezela ibhuleki lokunyathela amabhuleki nokucindezela iphedali kudinga umzamo owandisiwe, i-booster booster inephutha futhi kufanele ishintshwe. Kunconywa ukusebenzisa i-booster enesisindo (ithengiswa nge-master cylinder kit) ngoba ukuvuza kwe-master cylinder kuyimbangela enkulu yokwehluleka kwe-booster.

Uzodinga isithwebuli sokuxilonga, igeji yokuphatha ngesandla, i-digital volt / ohmmeter, nomthombo othembekile wolwazi lwemoto ukuthola ikhodi ye-P050F.

Ukuxilongwa kwekhodi ye-P050F kuzoqala (kimina) ngokuhlola okubonakalayo kwepayipi lokunikezela nge-vacuum booster. Uma ipayipi lixhunyiwe futhi lisebenza kahle, qala injini (KOER) bese uvikela imoto endaweni yokupaka noma engathathi hlangothi. Susa ngokucophelela i-valve yokuhlola eya endaweni eyodwa (ekugcineni kwepayipi le-vacuum) ku-booster bese uqinisekisa ukuthi kunendawo yokuphumula eyanele ku-booster. Uma ungabaza, ungasebenzisa igeji yokucindezela ngesandla ukuphatha i-vacuum.

Izidingo zokuhlanza injini zingatholakala kumthombo wolwazi lwemoto. Uma injini ingakhiphi isikhala esanele, kufanele ilungiswe ngaphambi kokuqhubeka nokuxilongwa. Uma i-booster ine-vacuum eyanele futhi ibonakala isebenza kahle, thintana nomthombo wolwazi lwemoto yakho ngezinqubo zokuhlola nokucaciswa. Kufanele futhi uthole imidwebo yezintambo, izixhumi ze-faceplates, nama-pinouts wokuxhuma. Lezi zinsiza zizodingeka ukwenza ukuxilongwa okulungile.

Isinyathelo 1

Ukhiye uvuliwe nenjini (KOEO), nqamula isixhumi ku-VBS bese usebenzisa ukuhola okuhle kokuhlola okuvela ku-DVOM ukubheka ugesi oyisithenjwa kuphini elifanele kusixhumi. Hlola ukuthola isisekelo ngokuhola okungalungile kokuhlolwa. Uma womabili amandla we-voltage nomhlabathi ekhona, iya kusinyathelo 2.

Isinyathelo 2

Sebenzisa i-DVOM (kusethingi ye-Ohm) ukuhlola i-VBS. Landela inqubo yokuhlola yomkhiqizi kanye nemininingwane yokuhlola i-VBS. Uma inzwa ingekho ebekiwe, ayisebenzi. Uma inzwa ilungile, iya kusinyathelo 3.

Isinyathelo 3

Nge-KOER, sebenzisa i-terminal enhle yengono ye-DVOM ukukala amandla wesiginali kusixhumi se-VBS. Phansi kokuhlolwa okungekuhle kuholele endaweni eyaziwayo yebhethri. Amandla wesiginali kufanele akhonjiswe ngezinga elifanayo nenzwa ye-MAP kusibonisi sedatha yesithwebuli. Igrafu yengcindezi kuqhathaniswa ne-vacu kuqhathaniswa ne-voltage nayo ingatholakala kumthombo wolwazi wemoto yakho. Qhathanisa i-voltage etholakala kusiginali yesiginali nokufaka okuhambisanayo kumdwebo. Ngisola ukuthi iVBS inephutha uma ingahambisani nomdwebo. Uma i-voltage ingaphakathi kokucacisiwe, iya kusinyathelo 4.

Isinyathelo 4

Thola i-PCM bese usebenzisa i-DVOM ukuqinisekisa ukuthi i-VBS signal circuit voltage ikhona lapho. Hlola isekethe yesiginali ye-VBS usebenzisa isivivinyo sokuhola esivela ku-DVOM. Xhuma isivivinyo esingesihle kumhlaba omuhle womhlaba. Uma isiginali ye-VBS oyitholile kusixhumi se-VBS ingekho kusekethe elihambelanayo kusixhumi se-PCM, sola ukuthi unesekethe evulekile phakathi kwe-PCM ne-VBS. Uma wonke amasekethe alungile futhi i-VBS ihlangabezana nokucaciswa; ungaba nenkinga ye-PCM noma iphutha lokuhlela le-PCM.

• Buyekeza ama-Bulletin Wensizakalo Yezobuchwepheshe (i-TSB) ngokufakwa okunekhodi nezimpawu ezifanayo. I-TSB efanele ingakusiza kakhulu ekuhlolweni kwakho.
