Karamin Tashin Mota: Gano Yaya Karamin Tashin Mota Ya Zama Yana Kwafi

Mota mai yanci da yanci a lokacin da aka tsara, ya kusantar da yanzu, ko ya yi yanci daga 500 zuwa 1,200 RPM ba tare da shawara na mutum ba, yana nuna alama mai kyau: wani abu a siffa na hawa ya kashe kuma yana zama babu karama. makullin jiki — wani abu mai yiwuwa wanda ya tsara hawa a cikin mota tare da wani karamin tashin mota — yana kamar yadda ya faruwa. Fasahar abin da ke kwafi karamin tashin mota yana farko da karamin tashin mota mai yiwuwa da karamin tashin mota mai yiwuwa.

Matsayin Karamin Tashin Mota Na Kwafi

Ayyukan Karbon da Hawa Ta Kwafi

Ayyukan karbon a cikin karamin tashin mota da kwallon karamin tashin mota yana kamar yadda ya faruwa makullin jiki yadda aiki. Gases na engine na kuma yin fuskanci na oil wanda ke zama layer na carbon na daidai a kan ƙarafi na plate da kuma a kan surface na bore. Gap na factory-calibrated na yawa wanda ke bada minimum idle airflow ya zama yawa ta hanyar takaici. ECU ya yi amfani da wider throttle opening, amma deposits na yawa suka haɗa da erratic airflow wanda idle control system ba za su iya stablize ba. Symptoms suna fito a farko kamar wandering cold idle, kuma suna dace da stalling lokacin da aka ci gaba kamar suka dace da thickening na deposits.

Kishin Na Signal Na Electronic Da Kishin Na Sensor Drift

Electronic makullin jiki wurin suka yi amfani da biyu potentiometers na gaba daya don fahimta wurin throttle — biyu kofin sinyal na gaba daya wanda suka buƙata suka ƙare da yawa a cikin tashin da aka ba shi. Idan biyu na potentiometer ya kara ko ya zama babu wani abu, sinyal su sun fara farko. ECU ya fahimci farko, ya shiga koda na kuskure P0120-P0123 ko P0220-P0223, kuma yana iya shiga mode na ‘limp-home’. Kuskuren da suka dace da kuskure suka fara da kuskure: sensor da ya kusantar da kuskure a wani yanki na hanyar yin kuskure ko a wani yanki na throttle yana iya tabbatar da kuskure a test na gaba daya amma yana iya haɗa kuskure na yin kuskure a lokacin da aka tsayayi a kofin kofin.

Wani Kasuwa na Al’ada: Fasahar Kuskure na Gaba Daya na Kuskure na Yawa

Wani VW Golf da engine na 1.6L ya zo a wurin ayyukan da ke cikin kuskure na yawa idan ya ci gaba na kofin kofin — ba koda na ‘check engine light’ ba, kuma koda na P0638 ce kuma. Muhassib ya saukar makullin jiki , ya gudumta ƙarfin ECU, kuma ya sanya maki. Yadda maki ya zama mai tsoro ya dace da tsoho na uku. A wani lokaci na biyu, alama na oscilloscope ta nuna cikin 300-millisecond voltage dropout a cikin wani potentiometer track a ɗan ɗaya na 12% throttle opening — wanda shine yanzu a lokacin deceleration don fuskanci na junctions. ECU ta fahimci wannan ne kamar yadda sensor ya kashe kuma ta amfani da throttle a lokacin da aka sa, wanda ya zama sabonin tsoro. Alama na musamman ta rufe kuma ta sanyawa da precision-manufactured makullin jiki daga Sakes Auto Parts (Shanghai) Co., Ltd., wanda suka yi calibration na gaba na karama da sensor output curves na OE don fuskanci wannan nau'in signal deviation.

Me Ya Sa Wani Kwallon Daga Zama Ba Ta Fi Gudumta Throttle Bodies Na Elektronik

Kwallon carbon ta fuskanci airflow a cikin units na mechanical sound amma ba ta iya gudumta potentiometer tracks na kusur, motors na throttle actuator na kusur, ko gears na gaba na kusur. Elektronik makullin jiki kadan kadan suka hada DC motor da plastic reduction gears wanda suka saita throttle plate. A cikin 100,000 zuwa 150,000 kilometers, teeth na gear suka faru backlash, wanda ya zama sababbin plate ya fi yadda ake amfani da shi da amfani da ECU ya nuna yadda ya yi aiki don samun angle mai zahiri. Wannan mechanical wear ya zama sababin surging idle wanda ke zama kamar carbon buildup amma yana bukatar a sanya maimakon a gurba. Sakes Auto Parts ta tsara kadan kadan maimakon da suka yi amfani da materials na gear wanda suka daga baya suka taimaka don gudanen wear patterns wanda suka zama babban a high-mileage VW da Audi engines.

Fara da borescope inspection na makullin jiki bore da plate don kammala carbon. Kwalla su ne a menga aerosol intake cleaner da soft brush — ba a iya amfani da abubuwan da suka kawo gurasa wanda suka kawo gurasa akan bore surface. Sanya ECU adaptation values bayan kwalla. Idan idle instability ya zama yanzu, graph both TPS signal voltages a lokacin slow accelerator pedal sweep. Wani voltage dropout, spike, ko deviation ne akan biyu na signal tracks yana nuna sensor wear wanda ke bukatar replacement. Yashe throttle actuator motor resistance a connector — values outside 1-5 ohms suna nuna motor winding da ya dace. A quality replacement from Sakes Auto Parts ya zo pre-calibrated, yana gyara risk of adaptation errors during installation.

Masu Sabon Gaskiya

Wane ne mabudin farko na failing throttle body?

Slight RPM fluctuation at idle, hesitation during light acceleration, da occasional stalling when the clutch is depressed. A worn makullin jiki zai iya haɗawa koda yanzu ba a nuna shi da ‘check engine light’ — koda yanzu ba a nuna shi da ‘check engine light’ wani nau’in kuskurin da ke bayani a cikin kuskuri na farko.

Zan iya tsofinta ta hanyar da aka ƙara gaskiya?

Tsofinta ta hanyar da aka ƙara gaskiya don samun gida na kuskuri zai iya aiki, amma tsofinta mai zuwa da kuskuri zai iya haɗawa kuskuri na ‘stalling’ a cikin tsofinta kuma zai iya haɗawa ECU don daina a ‘limp-home mode’ da karamin kudin da aka ƙara gaskiya.
