Malamba anthawi ndi maunyolo a BMW

Mwini aliyense wagalimoto ya BMW amadziwa kuti kuwongolera koyenera pamayendedwe anthawi yake ndikofunikira kwambiri. Ndi bwino kuti m'malo mwake aliyense makilomita 100, imodzi ndi tensioner, shock absorber, mpope madzi ndi nyenyezi.

Ngakhale kuti mtunda wolowa m'malo ukuwonetsedwa mu malangizo a wopanga, simuyenera kudalira lamuloli kwathunthu. Apo ayi, mukhoza kuphonya mphindi yoyenera, ndiyeno mudzayenera kulipira ndalama zambiri kuti mubweretse injini kuti ikhale yogwira ntchito.

Ndi nthawi yanji yosintha lamba wanthawi pa BMW

Choyamba, ndikofunikira kudziwa chomwe tcheni chanthawi ndi nthawi chomwe chiyenera kusinthidwa. Mapangidwe a msonkhano uno, omwe ntchito yake ndi kugwirizanitsa ntchito ya pistoni, ma valve ndi makina oyatsira, ndi ophweka kwambiri.

Ma crankshaft ndi camshaft sprockets amakhala malo a unyolo, nthawi yomweyo kuyendetsa mpope wamadzi.

Kuonetsetsa kuti unyolo ukuyenda bwino, chipangizo chapadera chotchedwa chain tensioner chimayikidwa. Ngati unyolo wathyoka, ma valve olowetsa ndi mpweya amamatira mu pistoni ndipo injini idzafunika kukonzanso kwakukulu. Injini sayenera kugwiritsidwa ntchito mpaka ntchito yokonza itatha.

Nthawi zambiri, oyendetsa galimoto amakumana ndi mavuto awa:

Maonekedwe pa chida gulu chizindikiro "Chongani injini"

Mfundoyi ikukhala vuto lofala kwambiri pamainjini agalimoto ndi magalimoto. Chifukwa chophatikizidwira m'gulu la zida ndikuzindikiritsa ndi electronic control unit (ECU) ya code yolakwika mu imodzi mwa machitidwe omwe alipo.

Chiwerengero cha zizindikiro zolakwa zomwe zilipo zimaposa 200. Kuti muzindikire molondola chifukwa chake, ndi bwino kuti muzindikire mu umodzi mwa mautumiki odalirika a galimoto.

Kuchuluka kwamafuta

Pakugwira ntchito moyenera kwa injini, zimatsimikizira kuti mafuta amawotchedwa pamlingo womwe umalola kuti azigwiritsa ntchito ndalama. Koma mbali zina za dongosolo la mafuta, monga zosefera mpweya ndi mafuta, kutuluka kwa mpweya wambiri ndi masensa a okosijeni, pang'onopang'ono zimakhudzidwa ndi kuipitsidwa ndi kuvala.

Ngati sanasinthidwe munthawi yake, yomwe ikukhala chifukwa chodziwika kwambiri chowonjezerera mafuta, izi zidzakulitsa kugwiritsa ntchito kwanu.

Kukuvutitsa

Zikatero, muyenera kutengera galimotoyo kwa makaniko mwachangu, pangafunike kusintha ma brake pads kapena ma disc.

Bwezerani unyolo wa nthawi pokhapokha utatambasulidwa. Ndikoyenera kuganizira osati nthawi yogwiritsira ntchito makina, komanso momwe amagwirira ntchito.

Zifukwa zosinthira unyolo wanthawi pa BMW

Malo a unyolo wa nthawi ndi injini, choncho sichikumana ndi zochitika zakunja ndipo imagwira ntchito mwakachetechete. Koma izi zimatha kuyambitsa kuwonongeka pafupipafupi.

Mphamvu pa ntchito ya makina ikuchitika kutengera mtundu wa mafuta anatsanulira mu injini ndi kuchuluka kwake. Ngati palibe mafuta okwanira, muyenera kusintha gawolo pamene likutha.

Kusintha kwa nthawi yayitali ndikofunikira pazifukwa izi:

• The tensioner wagwa m'mavuto;
• Kusagwira ntchito kwa hydraulic chain tensioner chifukwa cha kutsika kwamafuta. Unyolo ndi wothina ndipo mano akutsetsereka;
• Unyolo ukhozanso kutsetsereka chifukwa cha magiya a camshaft ovala;
• Ngati mafuta otsika akugwiritsidwa ntchito, lamba angafunikire kusinthidwa;
• Unyolo ukhoza kulephera pamene ukugwira ntchito pa katundu wambiri kapena mumayendedwe othamanga kwambiri.

Chifukwa chachikulu chomwe tcheni chanthawi chingafunikire kusinthidwa ndikuti ndizovuta kupeza. Izi zimasokoneza kupewa komanso kuzindikira munthawi yake kuwonongeka kwa nthawi yoyendetsa. Poyerekeza ndi chingwe chokonzekera, chimabisika pansi pa chiwerengero chachikulu cha casings. Kuti mufufuze, muyenera kusokoneza injini, ndipo si madalaivala onse omwe angakwanitse izi.

M'malo ikuchitika makilomita 100, chifukwa injini ali ndi kutentha mafuta, ndi mbali pulasitiki akhoza kusungunuka. Kukhalapo kwa hum pamene injini ikuyenda mothamanga kwambiri kudzakuthandizani kudziwa kukhalapo kwa vuto.

Kusintha kwanthawi yayitali pa BMW

Ukadaulo wosinthira unyolo ndi wosavuta, koma umafunikira chida chapadera, popanda chomwe sichingachitike.

Zotsatira zake zikhala motere:

•       Kutulutsa mafuta a injini;
•       Sungunulani nyumba yamoto ndikulowetsa gasket;
•       Chotsani chivundikiro cha valve ndikusintha gasket pansi;
•       Sambani ndondomeko ya nthawi;
•       Sambani ndi kuyeretsa injini kuchokera ku carbon deposits;
•       Ikani unyolo watsopano wanthawi;

Sonkhanitsaninso motsatira dongosolo.

Chidwi kwambiri chiyenera kuperekedwa ku mfundo yakuti panthawiyi m'pofunikanso kusintha ma bolts, chisindikizo cha mafuta a crankshaft kutsogolo ndi ma sprockets a nthawi.
