Nguva mabhandi nemacheni eBMW

Wese muridzi wemota yeBMW anoziva kuti kudzora kwakaringana mamiriro eiyo nguva yekutyaira kwakakosha. Zvakanakisisa kuitsiva makiromita 100 zviuru, panguva imwe chete neine tensioner, shock absorber, pombi yemvura uye nyeredzi.

Kunyangwe chokwadi chekuti nzvimbo yekutsiva inoratidzwa mumirayiridzo yekushandisa yemugadziri, haufanirwe kuvimba nemutemo uyu zvachose. Kana zvisina kudaro, iwe unogona kupotsa nguva yakakodzera, uye ipapo iwe uchafanirwa kubhadhara mari yakawanda kuunza injini kumamiriro ekushanda.

Ndeipi nguva yekuchinja bhandi renguva paBMW

Chekutanga pane zvese, zvakakosha kuziva kuti cheni yenguva chii uye painofanira kutsiviwa. Dhizaini yegungano iri, iro basa ndere kuwiriranisa mashandiro emapistoni, mavharuvhu uye inobatidza system, iri nyore kwazvo.

Iyo crankshaft uye camshaft sprockets inova iyo nzvimbo yeketani, panguva imwe chete ichityaira pombi yemvura.

Kuti ive nechokwadi chekugwinya kwakaringana kwecheni, mudziyo unokosha unonzi tensioner chain unoiswa. Kana ketani ikaputsika, mavharuvhu ekutora uye ekupera anonamatira mumapistoni uye injini inoda kuvandudzwa kukuru. Injini haifaniri kushandiswa kusvikira basa rekugadzirisa rapera.

Kazhinji, vatyairi vanosangana nematambudziko anotevera:

Kuonekwa pane chiridzwa chechiratidzo "Check injini"

Iyi poindi yave kuita dambudziko rinowanzoitika kune mota nerori injini. Chikonzero chekuiswa kwayo mumudziyo wemidziyo ndeyekuonekwa neelectronic control unit (ECU) yekodhi yekukanganisa mune imwe yehurongwa huripo.

Nhamba yose yekodhi yezvikanganiso iripo inodarika 200. Kuti unyatsoona chikonzero chacho, zviri nani kuongorora mune imwe yebasa remotokari rakavimbika.

Kuwedzera kushandiswa kwemafuta

Panguva yekushanda kweinjini, inoita kuti mafuta apiswe pamwero unobvumira kuti ishandiswe mune zvehupfumi. Asi zvimwe zvikamu zvehuturu system, senge mhepo nemafuta mafirita, kuyerera kwemhepo yakawanda uye ma sensors eokisijeni, zvishoma nezvishoma anoratidzwa nekusvibiswa uye kupfeka.

Kana dzikasatsiviwa nenguva, inova chikonzero chakakurumbira chekuwedzera kushandiswa kwemafuta, izvi zvinowedzera kushandisa kwako.

Kupopota kushungurudza

Mumamiriro ezvinhu akadaro, iwe unofanirwa kuendesa mota kune makanika nekukurumidza sezvinobvira, zvingave zvakakosha kutsiva mabhureki mapedhi kana madhisiki.

Tsiva cheni yenguva chete kana yakatambanudzwa. Zvakakodzera kufunga kwete chete nguva yekushandiswa kwemuchina, asiwo mamiriro ekushanda kwayo.

Zvikonzero zvekutsiva iyo nguva cheni paBMW

Nzvimbo yeketani yenguva ndiyo injini, saka haina ruzivo rwekunze uye inoshanda chinyararire. Asi chimiro ichi chinogona kukonzera kukanganisa kazhinji.

Kukanganisa kwekuita kwemuchina kunoitwa zvichienderana nemhando yemafuta anodururwa muinjini uye huwandu hwayo. Kana pasina mafuta akakwana, unozofanira kutsiva chikamu chacho sezvo chapera.

Nguva yekutsiviwa kweketani inodiwa nekuda kwezvikonzero zvinotevera:

• The tensioner yawira mukusagadzikana;
• Kusashanda kweiyo hydraulic chain tensioner nekuda kwekuderera kwemafuta. Cheni yakasimba uye mazino ari kutsvedza;
• Iyo ketani inogona zvakare kutsvedza semhedzisiro yemagiya ecamshaft akasakara;
• Kana mafuta akaderera akashandiswa, bhanhire rinogona kudiwa kuchinjwa;
• Iyo ketani inogona kukundikana kana ichishanda pamitoro yakakwira kana mune yakakwirira-kumhanya mode.

Chikonzero chikuru chetani yenguva ingangoda kutsiviwa imhaka yekuti inonetsa kuwana. Izvi zvinokanganisa kudzivirira uye kuona nenguva yekusashanda kweiyo nguva yekutyaira. Kuenzaniswa nekugadzirisa bhanhire, yakavanzwa pasi penhamba yakawanda yecasings. Kuti uite ongororo, iwe uchafanirwa disassemble injini, uye havasi vese vatyairi vanogona kubata izvi.

Kutsiviwa kunoitwa makiromita zviuru zana, sezvo injini ine tembiricha yakakwira yemafuta, uye zvikamu zvepurasitiki zvinogona kungonyungudika. Kuvapo kwehum kana injini ichimhanya nekumhanya kwakanyanya kunobatsira kuona kuvepo kwekusashanda.

Kutsiva cheni yenguva paBMW

Iyo ketani yekutsiva tekinoroji iri nyore, asi inoda chishandiso chakakosha, pasina icho hapana chinogona kuitwa.

Kurongeka kwezviito kuchave seinotevera:

•       Injini yemafuta inodonha;
•       Disassemble mota imba uye kutsiva gasket;
•       Bvisa chivharo chevhavha uye shandura gasket pasi;
•       Disassemble iyo nguva system;
•       Shamba uye uchenese injini kubva kune kabhoni deposits;
•       Isa ketani itsva yenguva;

Unganidza mune reverse order.

Kunyanya kutarisisa kunofanirwa kubhadharwa kune chokwadi chekuti panguva iyi inodiwa zvakare kutsiva mabhaudhi, kumberi crankshaft mafuta chisimbiso uye sprockets yenguva.
