Momwe mungayang'anire chothandizira?
Zamkatimu
Galimoto ikasiya kuthamanga nthawi zonse kapena kuwala kwa Check Engine kuyatsa, kuyesa kosinthira kothandizira kudzafunika. Ikhoza kutsekereza kapena kugwetsa zisa. bobbin ikhoza kuonongekanso. Kuti muwone chothandizira, mutha kuchichotsa kwathunthu kapena kugwiritsa ntchito njira popanda kuchotsa. Kuvuta kwa njira iyi kumadalira kuti mukufunikira wothandizira kuti agwire ntchito ndi mphamvu yamagetsi, simungathe kupirira nokha.
Zifukwa Zochotsera Catalyst
Pazovuta zoyamba pakugwira ntchito kwa chothandizira, eni magalimoto ogwiritsidwa ntchito amaganizira za kuchotsa chinthu ichi. Pakhoza kukhala zifukwa zingapo za izi.
Zifukwa zomwe ambiri amachotsa catalysts:
ena amanena kuti chothandiziracho chingalephere panthaŵi yosayenera;
wachiwiri akuganiza kuti m'malo movutitsidwa kwambiri ndi mafuta apanyumba, salola injini yoyaka mkati "kupuma mozama";
ena amakhulupirira kuti ngati mutachotsa kukana kopitilira muyeso, mutha kuwonjezera mphamvu ya ICE, komanso kuchepetsa kugwiritsa ntchito mafuta.
Koma, mwatsoka, oyendetsa galimoto ambiri omwe adakwera pansi pa hood ndi khwangwala ali ndi zodabwitsa zosasangalatsa - ndipo iyi ndi ECU (ICE control unit). chipika ichi chidzazindikira kuti palibe kusintha kwa mpweya wotulutsa mpweya usanayambe komanso pambuyo pa chothandizira ndipo udzapereka cholakwika.
Ndizotheka kunyenga chipikacho, koma mutha kuyisinthanso (njira iyi siitchulidwa m'nkhaniyi). Pazochitika zilizonse, pali njira (nkhanizi zikukambidwa pamabwalo a makina).
Tiyeni tione muzu wa zoipa - chikhalidwe cha "katalik". KOMA iyenera kuchotsedwa? Ambiri oyendetsa galimoto amatsogoleredwa ndi maganizo awo: galimotoyo inayamba kukoka bwino, "Ndikutsimikiza kuti chothandizira chatsekedwa ndipo ndicho chifukwa," ndi zina zotero. Sindidzawatsimikizira amakani, koma oganiza bwino amawerengabe. Kotero, zonse zomwe muyenera kuchita ndikuyang'ana mkhalidwe wa chothandizira, ndipo malingana ndi chikhalidwe chake, tidzatha kunena kuti chiyenera kuchotsedwa kapena kusinthidwa, koma nthawi zambiri amachotsedwa chifukwa cha mtengo wawo.
Onani chothandizira
Kuyang'ana chothandizira kuti chiloledwe ndi kutsekeka
Kotero, funso linabuka, "Kodi mungayang'ane bwanji chothandizira?". Njira yothandiza kwambiri komanso yosavuta ndiyo kuchotsa chothandizira ndikuchifufuza. Ngati kuwonongeka kwakukulu kwapezeka, chothandizira chikhoza kukonzedwa.
Timachotsa chothandizira ndikuyang'ana mkhalidwe wa maselo onse - kutsekedwa kwa maselo kungathe kufufuzidwa kuti athetsedwe, ndipo chifukwa cha izi kuwala kumakhala kothandiza. Koma sikuti zonse ndi zophweka monga momwe zikuwonekera. Nthawi zina, pakagwiritsidwa ntchito nthawi yayitali, chothandizira chimakakamira kwambiri Kuchotsa chothandizira kumatha kukhala ntchito yayitali komanso yosangalatsa. (Ineyo pandekha ndinamasula mtedza womangira kumbuyo kwa maola atatu, pamapeto pake sizinathandize - ndinayenera kuwadula pakati!). Ntchitoyi ndi yovuta kwambiri, chifukwa muyenera kugwira ntchito pansi pagalimoto.
Zizindikiro zazikulu ndi njira zowonera chothandizira ndikuti sichimatsekeka
pali palinso njira zingapo zowonera chothandizira:
- ndizotheka kuyeza utsi wazomwe zili muzinthu zoyipa (ndi chothandizira cholakwika, zomwe zili muzinthu zoyipa zimawonjezeka kwambiri poyerekeza ndi chothandizira chothandizira);
- mutha kuyang'ananso kupsinjika kwam'mbuyo potuluka (chizindikiro cha chothandizira chotsekeka ndikuwonjezeka kukana ndipo, chifukwa chake, kupanikizika).
Kuti muwunikire boma, muyenera kuphatikiza njira zonsezi.
Kuyang'ana chothandizira cha kupsinjika kwa msana
Kuyesedwa kwapambuyo kumbuyo
Zotsatirazi zikufotokoza njira yowunikira momwe chothandizira chimakhalira motsutsana ndi kuthamanga kwa msana.
Kuti tichite zimenezi, pamaso chothandizira, m`pofunika kuwotcherera zitsanzo zovekera kwa zitsanzo utsi mpweya. Ndikoyenera kuwotcherera zokometsera ndi ulusi ndi mawonekedwe a njira, izi ndizofanana ndi zopangira mapaipi oboola. Miyezo ikamalizidwa, mapulagi amakulungidwa muzophatikiza izi.
Oyimitsa makamaka zopangidwa ndi mkuwa - izi zidzawapatsa kumasula kwaulere panthawi ya ntchito. Pamiyeso, chitoliro cha brake 400-500 mm utali uyenera kusokonekera mu koyenera, ntchito yake ndikuchotsa kutentha kwakukulu. Timayika payipi ya mphira kumapeto kwa chubu, ndikumangirira payipi yoyezera, miyeso yake iyenera kukhala 1 kg / cm3.
Kupanikizika kumbuyo kungayesedwe pamene galimoto ikuthamanga ndi throttle yotseguka. Kupsyinjika kumatsimikiziridwa ndi kuthamanga kwachitsulo panthawi yothamanga, ndi kuwonjezeka kwa liwiro, mfundo zonse zimalembedwa. Zikachitika kuti mayendedwe akumbuyo kumbuyo akamagwira ntchito ndi damper yotseguka bwino pama liwiro aliwonse opitilira 0,35 kg / cm3, izi zikutanthauza kuti makina otulutsa ayenera kuwongolera.
Njira iyi yowonera chothandizira ndiyofunikira, komabe, m'moyo weniweni, zowotcherera ndi bizinesi yamatope. Chifukwa chake, ndidachita izi: Ndinamasula lambda yomwe imayima kutsogolo kwa chothandizira ndikuyika chopimitsira mphamvu kudzera pa adapta. (Ndikofunikira kugwiritsa ntchito choyezera kuthamanga bwino kwambiri mpaka 1 kg / cm3).
Monga adaputala, ndinagwiritsa ntchito payipi ya rabara, yomwe ndinasintha kukula ndi mpeni (musaiwale kuti kumangirira ndikofunikira).
Izi ndi momwe chida chautumiki cha akatswiri chimawonekera
Sam anamuyeza ndi payipi.
Kotero:
- Timayamba injini yoyaka mkati ndikuyang'ana kuwerengera kwa magetsi (ichi ndiye chotsitsa chakumbuyo).
- Timayika wothandizira kumbuyo kwa gudumu, amakweza liwiro mpaka 3000, timawerenga.
- Wothandizira amakwezanso liwiro, koma mpaka 5000, timawerenga.
ICE siyenera kupindika! Masekondi 5-7 ndi okwanira. Sikoyenera kugwiritsa ntchito chopimitsira choyezera mpaka 3 kg / cm3, chifukwa mwina sichingamve kupanikizika. Kuyeza kwamphamvu kwambiri ndi 2kg/cm3, kuposa 0,5 (kupanda kutero cholakwikacho chingakhale chofanana ndi muyeso). Ndinagwiritsa ntchito choyezera kuthamanga chomwe sichinali choyenera, koma nthawi yomweyo chiwongoladzanja chinali 0,5 kg / cm3, pazipita panthawi yowonjezereka kwachangu kuchokera ku XX mpaka 5000 (kupima kuthamanga kunagwedezeka ndikugwa "0"). Kotero, izi sizikuwerengera.
Ndipo mu malingaliro anga Njira ziwirizi zikhoza kuphatikizidwa motere:
1) masulani lambda patsogolo pa chothandizira;
2) m'malo mwa lambda iyi, timapukuta moyenerera;
3) sungani chidutswa cha chitoliro chophwanyika kuti chikhale choyenera (pali ndi mabawuti a mgwirizano);
4) kuika payipi kumapeto kwa chubu, ndi kukankhira mu kanyumba;
5) chabwino, ndiyeno, monga poyamba;
Kumbali inayi, timalumikizana ndi choyezera kuthamanga, chomwe muyeso wake umafikira 1 kg / cm3. M'pofunika kuonetsetsa kuti payipi si kukumana ndi tsatanetsatane wa dongosolo utsi.
Kupsyinjika kumatsimikiziridwa ndi kuthamanga kwapakati panthawi yothamanga, ndi kuwonjezeka kwa liwiro, mfundo zonse zimalembedwa. Zikachitika kuti mayendedwe akumbuyo kumbuyo akamagwira ntchito ndi damper yotseguka bwino pama liwiro aliwonse opitilira 0,35 kg / cm3, izi zikutanthauza kuti makina otulutsa ayenera kuwongolera.
6) chifukwa chosagwira ntchito (lambda yosasunthika, chekeyo idzayamba kuyaka), pambuyo pa kukhazikitsa lambda, chekecho chidzatuluka;
7) Malire a 0,35 kg / cm3 amagwiritsidwa ntchito pamagalimoto okonzedwa, koma kwa magalimoto abwinobwino, mwa lingaliro langa, kulolerana kumatha kupitilira 0,5 kg / cm3.
Ngati diagnostics wa chothandizira kusonyeza kuwonjezeka kukana ndi ndimeyi mpweya utsi, ndiye chothandizira ayenera kugubuduzika, ngati flushing sizingatheke, ndiye chothandizira ayenera m'malo. Ndipo ngati m'malo si zotheka zachuma, ndiye ife kuchotsa chothandizira. Mutha kudziwa zambiri za chothandizira cha backpressure muvidiyo ili pansipa:
