Motar Chery EASTAR B11 mai nisan mil kusan 80000, sanye take da watsawa ta atomatik da samfurin injin Mitsubishi 4g63. Mai amfani ya ba da rahoton cewa injin motar yana girgiza bayan farawa, kuma motar sanyi tana da tsanani. Maigidan ya kuma bayar da rahoton cewa, a bayyane yake a lokacin da ake jiran fitilun zirga-zirga (wato lokacin da motar ta yi zafi, injin yana girgiza da gaske a zaman banza).

Binciken kuskure: don injin mota da aka sarrafa ta lantarki, abubuwan da ke haifar da rashin kwanciyar hankali suna da rikitarwa sosai, amma ana iya bincikar kurakuran saurin aiki na gama-gari da kuma gano su ta fuskoki masu zuwa:

1. Rashin aikin injiniya

(1) Jirgin kasan bawul.

Abubuwan da ke haifar da kurakurai na yau da kullun sune: ① lokacin bawul ɗin ba daidai ba, kamar daidaitattun alamomin lokacin lokacin shigar da bel ɗin lokaci, yana haifar da mummunan konewa na kowane Silinda. ② Abubuwan watsa bawul ɗin suna sawa sosai. Idan daya (ko fiye) kyamarorin suna sawa ba bisa ka'ida ba, shaye-shayen da ake sarrafawa da bawuloli masu dacewa ba su daidaita ba, yana haifar da fashewar fashewar kowane silinda mara daidaito. ③ Ƙungiyar bawul ba ta aiki akai-akai. Idan hatimin bawul ɗin ba ta da ƙarfi, matsa lamba na kowane Silinda ba daidai ba ne, har ma da matsi na silinda ya canza saboda tsananin ajiyar carbon a kan bawul ɗin.

(2) Silinda block da crank haɗa sanda inji.

① Matsakaicin daidaituwa tsakanin silinda liner da piston ya yi girma sosai, "ƙaddamarwa uku" na zoben piston ba daidai ba ne ko rashin ƙarfi, har ma da "matching" na zoben piston yana faruwa. A sakamakon haka, matsa lamba na kowane Silinda ba daidai ba ne. ② Mugunyar ajiyar carbon a cikin ɗakin konewa. ③ Ma'auni mai ƙarfi na injin crankshaft, ƙwallon ƙafa da ƙwanƙwasa ƙwanƙwasa bai cancanta ba.

(3) Wasu dalilai. Misali, kushin kafar injin ya karye ko ya lalace.

2. Rashin tsarin shan iska

Sharuɗɗan gama gari suna haifar da kurakurai sun haɗa da:

(1) Yayyan nau'ikan kayan abinci ko wasu nau'ikan bawul iri-iri, kamar zub da iska na gasket ɗin shan ruwa, sassautawa ko fashewar bututun bututu, da sauransu, ta yadda iskar da bai kamata ta shiga cikin silinda ba, ta canza abin da ke gauraya, sannan yana haifar da mummunan konewar injin; Lokacin da ɗigon iska ya shafi kowane silinda kawai, injin zai girgiza da ƙarfi, wanda ke da tasiri a bayyane akan saurin rashin aiki.

(2) Wuce kima a kan magudanar ruwa da tashar jiragen ruwa. Na farko ya sa bawul ɗin maƙura ya makale kuma ya rufe a hankali, yayin da na ƙarshe zai canza sashin sha, wanda zai shafi sarrafawa da auna iskar sha da haifar da rashin kwanciyar hankali.

3. Laifi na yau da kullun da ke haifar da lalacewar tsarin samar da mai sun haɗa da:

(1) Tsarin man fetur na tsarin ba shi da kyau. Idan matsa lamba ya yi ƙasa, adadin man da aka allura daga injector ya ragu, kuma ingancin atomization ya zama mafi muni, wanda ya sa cakuda a cikin silinda ya yi laushi; Idan matsa lamba ya yi yawa, cakuda zai kasance mai wadata sosai, wanda zai sa konewa a cikin silinda maras kyau.

(2) Injector din mai da kansa ya yi kuskure, kamar an toshe rami na bututun ƙarfe, bawul ɗin allura ya makale ko na'urar solenoid ta ƙone.

(3) Siginar sarrafa allurar mai ba ta da kyau. Idan injector mai na silinda na iya samun gazawar kewaye, adadin allurar mai na wannan silinda zai yi daidai da na sauran silinda.

4. Rashin wutar lantarki

Sharuɗɗan gama gari suna haifar da kurakurai sun haɗa da:

(1) Rashin hasarar tartsatsin tartsatsin wuta da waya mai ƙarfi yana haifar da raguwa ko asarar wutar lantarki. Idan tazarar filogi ba ta dace ba, babban igiyar wutar lantarki tana zubar da wutar lantarki, ko ma ma'aunin calorific na filogin ba ta dace ba, konewar silinda kuma zai zama mara kyau.

(2) Rashin gazawar na'ura mai kunnawa da wutar lantarki zai haifar da ɓarna ko raunana ƙarfin wutar lantarki mai ƙarfi.

(3) Kuskuren kusurwa na gaba.

5. Laifin gama gari da kurakuran tsarin sarrafa injin injin ke haifar sun haɗa da:

(1) Idan injin lantarki kula da module (ECU) da daban-daban shigarwa sakonni kasa, misali, da engine crankshaft gudun siginar da Silinda saman matattu cibiyar siginar sun ɓace, da ECU zai daina fitarwa da ƙonewa siginar zuwa ga ƙonewa module, da kuma Silinda zai yi kuskure.

(2) Rashin gazawar tsarin sarrafa saurin aiki, kamar injin stepper mara aiki (ko bawul ɗin solenoid mara aiki) makale ko mara aiki, da aikin koyan kai na al'ada.

Ƙirƙirar matakan:

1. Tabbacin farko na gazawar abin hawa

Bayan tuntuɓar motar da ba ta dace ba, an sanar da mai shi ta hanyar bincike cewa motar ta yi rawar jiki da sauri bayan ta tashi; Na duba filogi na tartsatsin na gano cewa akwai ajiyar carbon a kan filogin. Bayan maye gurbin walƙiya, na ji cewa an rage jitter, amma har yanzu laifin yana nan.

Bayan fara injin a wurin, an gano cewa abin hawa yana jitters a fili, kuma abin da ya faru na kuskure ya wanzu: bayan fara sanyi, babu matsala a cikin babban matakin rashin aiki. Bayan babban aiki ya ƙare, abin hawa yana jitter ba shakka a cikin taksi; Lokacin da zafin ruwa ya zama al'ada, ana rage mitar girgiza. Ana jin da hannu a bututun hayakin cewa shaye-shayen ba ya daidaita lokaci-lokaci, tare da “konewa bayan” kama da ɗan ƙarar fashewar bututun da ba daidai ba.

Bugu da ƙari, mun koyi daga tattaunawar cewa motar mai shi ana amfani da ita don yin tafiya da kuma bayan aiki, mai nisan kilomita 15 ~ 20 a kowane lokaci, kuma ba kasafai yake tafiya cikin sauri ba. Lokacin jiran fitilun zirga-zirga ya tsaya, ya zama al'ada a taka birki, kuma madaidaicin motsi baya komawa gear "n".

2. Gano laifin daga sauki zuwa waje, sannan a tantance laifin daga sauki zuwa waje.

(1) Duba hawa huɗu (claw pads) na haɗin injin, kuma gano cewa akwai ɗan alamar tuntuɓar juna tsakanin robar dutsen dama da jikin. Ƙara sharewa ta ƙara shims zuwa screws masu hawa, fara abin hawa don gwaji, kuma jin cewa an rage jitter a cikin taksi. Bayan gwajin sake kunnawa, jitter har yanzu yana bayyane bayan ƙarshen babban aiki. A hade tare da sabon abu na m shaye, za a iya ganin cewa babban dalilin shi ne ba dakatar, amma m aiki na engine.

(2) Bincika tsarin sarrafa lantarki tare da kayan aikin bincike. Babu lambar kuskure a saurin aiki; Binciken kwararar bayanai shine kamar haka: shan iska yana da kusan 11 ~ 13kg / h, girman allurar man fetur shine 2.6 ~ 3.1ms, 3.1 ~ 3.6ms bayan an kunna kwandishan, kuma zafin ruwa shine 82 ℃. Yana nuna cewa injin ECU da tsarin sarrafa lantarki na injin suna da mahimmanci.

(3) Duba tsarin kunna wuta. An gano cewa babban layin wutar lantarki na Silinda 4 ya lalace da zubar da wutar lantarki. Sauya babban layin wutar lantarki na wannan silinda. Fara injin kuma kuskuren ba a inganta sosai a cikin saurin aiki ba. Tun da mai shi bai daɗe da maye gurbin tartsatsin tartsatsin ba, za a iya yin watsi da laifin da tartsatsin ya haifar.

(4) Duba tsarin samar da mai. Haɗa ma'aunin duba matsi na tabbatarwa zuwa da'irar mai na tsarin samar da mai tare da mai haɗa te. Bayan fara injin, hanzarta kuma matsakaicin matsa lamba mai zai iya kaiwa 3.5bar. Bayan 1h, matsa lamba har yanzu ya kasance 2.5bar, yana nuna cewa tsarin samar da man fetur al'ada ne. Yayin da ake watsewa da kuma duba injinan mai, an gano cewa injin mai na Silinda 2 yana da irin wannan al'amari na digowar mai, kamar yadda aka nuna a hoto na 1. Sauya madaidaicin injector na Silinda 2. Fara injin kuma kuskuren har yanzu ba za a iya kawar da shi ba.
