IMisa air flow inzwa
Okuqukethwe
I-DMRV noma inzwa ye-maf - kuyini? Igama elilungile lenzwa inzwa ye-Mass Airflow, sivame ukuyibiza ngokuthi i-flow meter. Umsebenzi wayo ukukala umthamo womoya ongena enjinini ngeyunithi yesikhathi.
Ukuthi isebenza kanjani
Inzwa iyintambo yeplatinamu (ngakho-ke ayishibhile), lapho kudlula khona amandla kagesi, ukuwashisa. Intambo eyodwa iyintambo yokulawula, umoya udlula owesibili, uwupholise. Inzwa ikhiqiza isignali ye-frequency-pulse, imvamisa yayo ehambisana ngokuqondile nenani lomoya odlula inzwa. Isilawuli sibhalisa izinguquko ku-current edlula okwesibili, i-filament epholile futhi ibala inani lomoya ongena emotweni. Kuye ngokuvama kwamasignali, isilawuli sibeka ubude be-injection kaphethiloli ngokulungisa isilinganiso somoya kanye nophethiloli engxubeni yamafutha. Ukufundwa kwenzwa yokugeleza komoya omkhulu kuyipharamitha eyinhloko isilawuli asetha ngayo ukusetshenziswa kukaphethiloli kanye nesikhathi sokuthungela. Ukusebenza kwemitha yokugeleza akuthinti kuphela ukusetshenziswa kukaphethiloli jikelele, ikhwalithi yengxube, amandla enjini, kodwa futhi, ngokungaqondile, insiza yenjini.
Kwenzekani uma ukhubaza i-MAF?
Ake siqale ngeqiniso lokuthi lapho imitha yokugeleza icishiwe, injini ingena kumodi yokusebenza okuphuthumayo. Lokhu kungaholela kuphi? Ngokuya ngemodeli yemoto futhi, ngokufanele, i-firmware - ukumisa injini (njengakuToyota) ukwandisa ukusetshenziswa kukaphethiloli noma ... kube yize. Uma sibheka imilayezo eminingi evela ezithangamini ezizenzakalelayo, abahloli baphinde baqaphele ukukhuphuka kokuqina ngemuva kokuvalwa kanye nokungabikho kokwehluleka ekusebenzeni kwenjini. Akekho owenze izilinganiso ngokucophelela zezinguquko ekusetshenzisweni kukaphethiloli nempilo yenjini. Ukuthi kuyafaneleka yini ukuzama ukukhohlisa okunjalo emotweni yakho kumnikazi ukuthi anqume.
Izimpawu zokungasebenzi kahle
Ngokungaqondile, ukungasebenzi kahle kwe-DMRV kungahlulelwa ngezimpawu ezilandelayo:
- Isibani se-CHEK ENGINE sikhanyisa;
- Imoto igijima kancane (isiphukuphuku);
- Ukusebenza okungazinzile kwenjini ngokungenzi lutho;
- Injini ayiqali "kushisa";
- Ukwanda kokusetshenziswa kukaphethiloli;
- Izitebele zenjini uma ushintsha amagiya.
Izimpawu ezichazwe ngenhla zingabangelwa ezinye izizathu, ngakho-ke kungcono ukwenza isheke elinembile lenzwa yokugeleza komoya omkhulu esiteshini sesevisi usebenzisa imishini ekhethekile. Uma singekho isikhathi, awufuni, noma uhawukela imali, ungabheka ukusebenza kwe-DMRV ngokwakho ngokuphezulu, kodwa hhayi u-100% wokuqiniseka.
Ukuxilongwa kwenzwa yokugeleza komoya okukhulu
Ubunzima bokuzihlonza kwe-flowmeter bubangelwa ukuthi lokhu kuyithuluzi elingenangqondo. Ukuthatha ukufundwa ngenani lama-revolutions aboniswe encwadini ngokuvamile akunikezi imiphumela. Ukufundwa kujwayelekile, kepha inzwa inephutha. Nazi izindlela ezimbalwa zokuxilonga impilo yezinzwa:
- Indlela elula ukushintsha i-DMRV ufake efanayo bese uhlola umphumela.
- Hlola ngaphandle kokumiselela. Nqamula i-flowmeter. Khipha isixhumi senzwa bese uqala injini. Uma i-DMVR ivaliwe, isilawuli sisebenza kumodi yesimo esiphuthumayo. Inani lamafutha engxube linqunywa kuphela isikhundla se-throttle. Kulokhu, injini igcina ijubane ngaphezu 1500 rpm. Uma imoto yaba "ishesha" ku-test drive, cishe kungenzeka ukuthi inzwa inephutha
- Ukuhlolwa okubonakalayo kwe-MAF. Khipha ishubhu lokungenisa umoya likathayela. Okokuqala, hlola ngokucophelela ukubola. Inzwa ingase ibe sesimweni esihle, futhi imbangela yokusebenza kwayo engazinzile ukuqhekeka kwepayipi likathayela. Uma ingaphezulu liphelele, qhubeka nokuhlola. Izakhi (izintambo ze-platinum) kanye nendawo yangaphakathi ye-corrugation kumele ibe yomile, ngaphandle kwemikhondo yamafutha nokungcola. Isizathu esingenzeka kakhulu sokungasebenzi kahle ukungcoliswa kwezakhi ze-flowmeter..
- Ihlola i-MAF nge-multimeter. Indlela iyasebenza ku-Bosh DMRV enezinombolo zekhathalogi 0 280 218 004, 0 280 218 037, 0 280 218 116. Sishintsha isihloli ukuze silinganise amandla kagesi aqondile, ngomkhawulo wokulinganisa ongu-2 Volts.
Umdwebo wokuxhumana we-DMRV:
Indawo isuka eseduze newindshield ngokulandelana 1. okokufaka kwesiginali yenzwa 2. I-DMRV supply voltage output 3. grounding (ground). 4. okukhiphayo edluliselwe phambili. Umbala wezintambo ungahluka, kodwa ukuhlelwa kwephini kuhlale kufana. Sivula i-ignition ngaphandle kokuqala injini. Sixhuma i-probe ebomvu ye-multimeter ngokusebenzisa izimpawu zenjoloba zesixhumi kothintana naye wokuqala (ngokuvamile ucingo oluphuzi), kanye nophenyo olumnyama luye kwesithathu kuya phansi (ngokuvamile ucingo oluluhlaza). Sibheka ukufundwa kwe-multimeter. Inzwa entsha ivamise ukufunda phakathi kuka-0.996 no-1.01 volts. Njengoba isikhathi siqhubeka, ukucindezeleka ngokuvamile kuyanda. Inani elikhulu lihambisana nokugqokwa kwenzwa okwengeziwe. 1.01 ... 1.02 - inzwa iyasebenza. 1.02 ... 1.03 - isimo akusona esingcono kakhulu, kodwa sisebenza 1.03 ... 1.04 - insiza isemngceleni. 1.04 ... 1.05 - ubuhlungu 1.05 ... nokuningi - nakanjani, sekuyisikhathi sokushintsha.
Zonke izindlela ezingenhla zokuxilonga ekhaya azinikezi isiqinisekiso esingu-100% sokuthembeka komphumela. Ukuxilongwa okuthembekile kungenziwa kuphela emishinini ekhethekile.
Zenzele ngokwakho ukuvimbela kanye nokulungiswa kwe-DMRV
Ukushintshwa okufika ngesikhathi kwesihlungi somoya nokuqapha isimo samasongo e-piston nezimpawu kukuvumela ukuba welule impilo ye-DMRV. Ukugqokwa kwabo kudala ukugcwala ngokweqile kwamagesi e-crankcase namafutha. Ifilimu yamafutha, ewela ezintweni ezibucayi zenzwa, iyayibulala. Kwinzwa esaphila, ukufunda okuntantayo kungabuyiswa ngohlelo lwe-“MARV corrector.” Ngosizo lwayo, ungakwazi ukushintsha ngokushesha ukulinganiswa kwe-MARV ku-firmware. Uhlelo kulula ukulithola nokulanda ngaphandle kwezinkinga ku-inthanethi. Ukusiza ukuvuselela inzwa engasebenzi, isicoci se-luftmassensensor reiniger singasiza. Ukuze wenze lokhu udinga:
- Susa inzwa enjinini njengoba kuchazwe ngenhla.
- Fafaza ukulungiswa ngokucophelela nangokukhululekile entweni ebucayi.
- Linda kuze kuphele ukungcola okusele.
- Yomisa inzwa kahle ngaphambi kokufaka. Ukuze kuvinjelwe, inqubo ingaphinda iphindwe ngaphambi kokushintshwa ngakunye kwesihlungi somoya.
Uma ukuhlanza kwehluleka, inzwa enesici kufanele ishintshwe. Izindleko zenzwa yokugeleza komoya isuka kuma-ruble angama-2000, futhi kumamodeli angenisiwe ngokuvamile aphezulu kakhulu, ngokwesibonelo, intengo yenzwa yeToyota 22204-22010 imayelana nama-ruble angama-3000. Uma inzwa ibiza, ungajahi ukuthenga entsha. Ngokuvamile, imikhiqizo yokumaka okufanayo ifakwe ezinkampanini ezahlukene zezimoto, futhi intengo njengezingxenye ezisele ihlukile. Le ndaba ivame ukubonakala ku-Bosh DMRV. Inkampani inikeza izinzwa ezifanayo ze-VAZ kanye namamodeli amaningi angenisiwe. Kudingekile ukuqaqa inzwa, bhala phansi ukumaka kwento ebucayi kakhulu, kungenzeka ukuthi ingashintshwa nge-VAZ eyodwa.
I-DBP esikhundleni se-DMRV
Ezimotweni ezingenisiwe, kusukela ngeminyaka yawo-2000, esikhundleni semitha yokugeleza, igeji yokucindezela (DBP) ifakiwe. Izinzuzo ze-DBP yijubane eliphezulu, ukwethembeka nokungathobeki. Kodwa ukufaka esikhundleni se-DMRV kuyindaba yalabo abathanda ukushuna kunabashayeli abajwayelekile.
