Renault G9U injini
Zamkatimu
Mainjiniya aku France apanga ndikuyika gawo lina lamagetsi, lomwe limagwiritsidwabe ntchito pama minibasi am'badwo wachiwiri. Mapangidwewo adakhala ofunikira ndipo nthawi yomweyo adapeza chifundo cha oyendetsa galimoto.
mafotokozedwe
Mu 1999, magalimoto atsopano (panthawi imeneyo) a banja la "G" anayamba kugubuduza kuchokera pamzere wa msonkhano wa "Renault Auto". Kutulutsidwa kwawo kunapitilira mpaka 2014. Injini ya dizilo ya G9U idakhala chitsanzo choyambira. Ndi 2,5-lita mu mzere turbodiesel anayi yamphamvu ndi mphamvu 100 kuti 145 HP ndi makokedwe 260-310 Nm.
Injini idayikidwa pamagalimoto a Renault:
- Master II (1999-2010);
- Magalimoto II (2001-2014).
Pamagalimoto a Opel/Vauxhall:
- Movano A (2003-2010);
- Vivaro A (2003-2011).
Pa magalimoto a Nissan:
- Interstar X70 (2003-2010);
- Primastar X83 (2003-2014).

Kwa nthawi yonse yopanga, injini yakhala ikuwongolera mobwerezabwereza. Kusintha kwakukulu kwachitsanzo choyambira kwakhudza mphamvu, torque ndi chiŵerengero cha kuponderezana. Gawo lamakina limakhalabe lomwelo.

Kudalirika, zofooka, kusakhazikika
Makhalidwe aukadaulo a injini adzakhala athunthu ngati zinthu zazikulu zogwirira ntchito zimalumikizidwa nayo.
Kudalirika
Ponena za kudalirika kwa injini yoyaka mkati, ndikofunikira kukumbukira kufunika kwake. Zikuwonekeratu kuti galimoto yotsika, yosadalirika sidzakhala yotchuka pakati pa eni galimoto. G9U ilibe zolakwika izi.
Chimodzi mwa zizindikiro zazikulu za kudalirika ndi moyo utumiki wa injini. M'malo mwake, ndikukonza munthawi yake, kumapitilira 500 zikwi zikwi zamakilomita osakonza. Chiwerengerochi chimatsimikizira osati kukhazikika, komanso kudalirika kwa mphamvu yamagetsi. Tiyenera kukumbukira kuti si injini iliyonse yomwe imagwirizana ndi zomwe zanenedwa. Ndi chifukwa chake.
Kudalirika kwakukulu kwa gawo lamagetsi kumatsimikiziridwa osati ndi njira zatsopano zopangira, komanso ndi zofunika zokonza zokhazikika. Kupitilira masiku omalizira potengera ma mileage komanso nthawi yakukonzanso kotsatira kumachepetsa kwambiri kudalirika kwa injini yoyaka mkati. Kuphatikiza apo, wopanga amaika zofunikira pakuwonjezeka kwa zinthu zomwe zimagwiritsidwa ntchito komanso mafuta ndi mafuta omwe amagwiritsidwa ntchito.
Zosafunikira m'mikhalidwe yathu yogwirira ntchito ndi malingaliro a madalaivala odziwa zambiri komanso akatswiri odziwa ntchito zamagalimoto. Makamaka za kuchepetsa chuma pakati pa mautumiki. Mwachitsanzo, amalangiza kusintha mafuta osati pambuyo makilomita zikwi 15 (monga tanena mu malamulo utumiki), koma m'mbuyomo, pambuyo makilomita 8-10 zikwi. Zikuwonekeratu kuti ndi njira yotereyi yokonza, bajetiyo idzachepetsedwa pang'ono, koma kudalirika ndi kukhazikika kudzawonjezeka kwambiri.
Kutsiliza: injini ndi yodalirika ndi yake yokonza yake ndi yoyenera.
Mawanga ofooka
Ponena za zofooka, malingaliro a eni magalimoto amalumikizana. Iwo amakhulupirira kuti mu injini zoopsa kwambiri ndi:
- lamba wanthawi yosweka;
- kusagwira bwino ntchito mu turbocharger komwe kumayenderana ndi kutuluka kwa mafuta mukudya;
- valavu ya EGR yotsekedwa;
- kuwonongeka kwa zida zamagetsi.
Akatswiri ogwira ntchito zamagalimoto amawonjezera kuwonongeka kwa mutu wa silinda pambuyo powakonza okha. Nthawi zambiri, izi ndi ulusi wosweka pansi pa bedi la camshafts. Zida zamafuta sizinasiyidwe popanda chidwi. Komanso nthawi zambiri zimalephera chifukwa cha kuipitsidwa ndi mafuta otsika a dizilo.
Tiyeni tiwone chifukwa chake izi zimachitika komanso zomwe zikuyenera kuchitika kuti athetse mavutowa.
Mlengi anatsimikiza gwero la nthawi lamba pa 120 makilomita zikwi za galimoto. Kuposa mtengo uwu kumabweretsa kupuma. Mchitidwe wogwiritsa ntchito galimoto m'mikhalidwe yathu, yomwe ili kutali ndi ku Europe, ikuwonetsa kuti nthawi zonse zovomerezeka zosinthira zinthu zogwiritsidwa ntchito ziyenera kuchepetsedwa. Izi zikugwiranso ntchito ku lamba. Choncho, m'malo ake pambuyo 90-100 Km idzawonjezera kudalirika kwa injini ndi kupewa kusapeŵeka kwa kukonza kwambiri ndi okwera mtengo wa yamphamvu mutu (rockers kupinda ngati yopuma).
Turbocharger ndi njira yovuta, koma yodalirika kwambiri. Kukonzekera kwa injini panthawi yake ndikusintha zinthu zomwe zimagwiritsidwa ntchito (mafuta, mafuta ndi zosefera mpweya) zimathandizira kugwira ntchito kwa turbine, zomwe zimatalikitsa moyo wake wautumiki.
Kutsekeka kwa valavu ya EGR kumachepetsa kwambiri mphamvu ya injini yoyaka mkati, kusokoneza chiyambi chake. Cholakwika ndi kutsika kwamafuta athu a dizilo. Pankhani iyi, woyendetsa galimoto alibe mphamvu yosintha chilichonse. Koma pali njira yothetsera vutoli. Choyamba. Ndikofunikira kuthamangitsa valavu pamene imakhala yotsekeka. Chachiwiri. Thirani mafuta m'galimoto pokhapokha pamalo okwerera mafuta ovomerezeka. Chachitatu. Zimitsani valavu. Kulowerera koteroko sikungabweretse vuto kwa injini, koma muyezo wachilengedwe wotulutsa mpweya wotulutsa mpweya udzachepa.
Zolakwika pazida zamagetsi zimathetsedwa ndi akatswiri apadera oyendetsa magalimoto. Injiniyo ndi yaukadaulo wapamwamba kwambiri, chifukwa chake kuyesayesa konse kuti muthetse vuto lanu, monga lamulo, kulephera.
Kusungika
Kusamalira bwino si vuto. Cast iron block imakupatsani mwayi wonyamula masilinda mpaka kukula kulikonse kokonzekera. Kuphatikiza apo, pali zambiri pakuyika kwa ma cartridge mu chipika (makamaka, 88x93x93x183,5 ndi kolala). Kutopetsa kumapangidwa pansi pa kukula kwa pistoni, ndipo panthawi ya manja, mphete za pistoni zokha zimasintha.
Kusankhidwa kwa zida zosinthira sizovuta. Amapezeka muzosiyana zilizonse m'masitolo apadera kapena pa intaneti. Posankha magawo olowa m'malo, zokonda ziyenera kuperekedwa kwa zoyambirira. Nthawi zina, mungagwiritse ntchito analogues. Zida zotsalira zomwe zimagwiritsidwa ntchito (kuchokera ku dismantling) siziyenera kugwiritsidwa ntchito kukonzanso, chifukwa khalidwe lawo nthawi zonse limakayikira.
Kubwezeretsanso kwa injini kuyenera kuchitidwa pa ntchito yapadera yamagalimoto. Muzochitika za "garaja", izi siziyenera kuchitidwa chifukwa chazovuta kuyang'anira kukonza. Mwachitsanzo, kupatukana kuchokera kwa wopanga komwe akulimbikitsidwa kumangirira makokedwe omangirira mabedi a camshaft kumayambitsa kuwonongeka kwa mutu wa silinda. Pali ma nuances ambiri ofanana pa injini.
Choncho, kukonza injini kuyenera kuchitidwa ndi akatswiri odziwa bwino ntchito.
Chizindikiritso cha injini
Nthawi zina zimakhala zofunikira kudziwa kupanga ndi nambala ya injini. Izi ndizofunikira makamaka pogula injini ya mgwirizano.
Pali ogulitsa osakhulupirika omwe amagulitsa malita 2,5 m'malo mwa 2,2 malita DCI. Kunja, ndi ofanana kwambiri, ndipo kusiyana kwa mtengo kuli pafupi $ 1000. Katswiri wodziwa bwino yekha amatha kusiyanitsa mitundu ya injini. Chinyengo chikuchitika mophweka - dzina la dzina lomwe lili pansi pa silinda limasintha.
Pamwamba pa chipikacho pali nambala ya injini, yomwe siingapangidwe. Zimapangidwa ndi zizindikiro zojambulidwa (monga pa chithunzi). Itha kugwiritsidwa ntchito kudziwa kuchuluka kwa injini poyang'ana deta ya wopanga, yomwe ili pagulu.
Malo a mbale zozindikiritsa akhoza kusiyana malinga ndi kusinthidwa kwa injini yoyaka mkati.
Renault G9U turbodiesel ndi gawo lolimba, lodalirika komanso lachuma lomwe limakonza munthawi yake komanso zapamwamba.
