Musanalowe m'malo, m'pofunika kuchita opaleshoni monga raskosovka - kuyeretsa mphete za pistoni kuchokera ku mwaye, ndipo pambuyo pake - fufuzani zomwe zili muzitsulo.

Kutambasulira kwa nthawi ya unyolo

Nissan MR20DE injini Zitha kusokonezedwa ndi kutsekeka kwamphamvu, chifukwa zizindikiro ndizofanana: kusagwira ntchito molingana, kulephera kwadzidzidzi mu injini (omwe ali ofanana ndi kulephera kwa imodzi mwa ma spark plugs), kuchepetsedwa mphamvu zamagetsi, kugogoda panthawi yothamangitsa.

Njira yosinthira nthawi iyenera kusinthidwa. Mtengo wa zida zanthawi ndi wotsika mtengo, koma mutha kugulanso zabodza. Kusintha unyolo ndi mofulumira, mtengo wa ndondomeko si mkulu.

Mawonekedwe a mluzu wakuthwa komanso wosasangalatsa

Mluzuwo umamveka pa injini yotenthetsera yosakwanira. Phokoso limachepa pang'onopang'ono kapena kutha kwathunthu kutentha kwa injini kukakwera. Chifukwa cha mluzu uwu ndi lamba lomwe limayikidwa pa jenereta. Ngati panja palibe zolakwika zomwe zimawoneka, ndiye kuti lamba wa alternator ukhoza kumangika komwe kuli flywheel. Ngati sprains kapena ming'alu ikuwoneka, ndiye kuti lamba wa alternator amasinthidwa bwino ndi watsopano.

Momwe mungasinthire bwino ma spark plugs

Zomwe zili pamwambazi sizowopsa ngati zichotsedwa munthawi yake. Koma ntchito yosavuta ngati makokedwe a spark plugs ikhoza kukhala tsoka lenileni, pambuyo pake ndikofunikira kusintha unyolo wamutu wa silinda kapena lamba.

Limbitsani ma spark plugs pa mota ya MR20DE kokha ndi wrench ya torque. Mphamvu ya 20Nm siyenera kupitirira. Ngati mphamvu yochulukirapo ikugwiritsidwa ntchito, ndiye kuti ma microcracks amatha kuchitika pazingwe zomwe zili mu chipika, zomwe zingayambitse katatu. Pamodzi ndi kuthamanga kwa injini, komwe kumawonjezeka molingana ndi makilomita omwe akuyenda, mutu wa chipikacho ukhoza kuphimbidwa ndi zoziziritsa kukhosi, galimotoyo imagwira ntchito mu jerks, makamaka pamene HBO yaikidwa.

Chifukwa chake, ndikofunikira kugwiritsa ntchito wrench ya torque. Ndipo ndi bwino kusintha ma spark plugs pa injini yozizira.

Ndi mafuta ati omwe ali abwino kudzaza injini

Kuti gwero la injini ya MR20DE ligwirizane ndi zomwe zafotokozedwa muzolemba zamakono, zogwiritsira ntchito zonse ziyenera kusinthidwa nthawi: zosefera zamafuta ndi mafuta, komanso mafuta. Pampu yamafuta iyeneranso kuyang'aniridwa nthawi ndi nthawi. Kuphatikiza pa kusintha zinthu zogwiritsira ntchito, ma valve ayenera kusinthidwa nthawi ndi nthawi (kwa moyo wautali wautumiki, ayenera kusinthidwa pa 100000 km iliyonse).

Wopanga magalimoto a MR20DE amalangiza kugwiritsa ntchito mafuta apamwamba okha, monga Elf 5W40 kapena 5W30. Inde, pamodzi ndi mafuta, fyuluta imasinthanso. Elf 5W40 ndi 5W30 ali ndi mamasukidwe akayendedwe abwino ndi kachulukidwe, ndipo akhoza kukhala kwa nthawi yaitali. Koma ndibwino kuti musasinthe mafuta pamtunda uliwonse wa makilomita 15000 (monga momwe tafotokozera mwatsatanetsatane), koma kuchita opaleshoniyi nthawi zambiri - pambuyo pa 7500-8000 Km ndikusamalira poto ya injini.

Ponena za mafuta, ndibwino kuti musawononge ndalama ndikudzaza injini ndi mafuta octane osachepera 95, monga buku lokonzekera limanenera. Komanso, tsopano pali chiwerengero chachikulu cha zowonjezera pa msika zomwe zingapulumutse osati mafuta okha, komanso moyo wa injini.
