Kukonza ndi diagnostics wa zonenepa injini ndi manja awo

yamphamvu ndi yofunika zikuluzikulu za injini, chifukwa pa mfundo izi zimachitika matenthedwe mphamvu kutembenuka mu mphamvu mawotchi. yamphamvu ndi chipinda kuyaka kwa mafuta osakaniza mpweya ndi mafuta kapena mafuta ena malinga ndi mtundu engine. Mmene yamphamvu umamumvera katundu mkulu ndi zinthu kutentha kwa ntchito yake chimachitika ndi mavuto ambiri.

Choncho ndikofunika kusunga ntchito iliyonse ya zonenepa a injini. The malfunctions zofunika, komanso kupunduka chifukwa muli m'malo kapena kukonza chipika injini, womwe ndi yamphamvu inabala ndi pisitoni unsembe kukonza kukula kwake. Koma ngati muli ndi injini dizilo, Ndi bwino kulankhula ndi pakati utumiki amene specialization yokonza injini dizilo.

Ndi kukula kusiyana pakati pa pisitoni ndi khoma yamphamvu pali imfa ya mphamvu monga injini psinjika dontho zikachitika, amene ana amakumana ndi mavuto aakulu. Chifukwa kugwa kwa injini psinjika makokedwe dontho zikachitika, komanso patsogolo kugwa kwa crankshaft kwa mafuta chakudya.

Tikonze kapena kuchotsa zovuta izi - nthaŵi zambiri malo yamphamvu inabala kukonza pistons wa awiri akuluakulu. Pambuyo kuti injini komanso chitadutsa, ndi kuthamanga-akupera panthawi yopuma imeneyi.

Jaji wa Leya anaberekera yamphamvu ndi n'kofunika kuyamba kuchotsa mutu wa chipika injini ndi limagwirira decompression, pambuyo kuchotsa chivundikiro cha chipika engine. Unscrewed nati zitsulo wrench crosswise kupewa kuchucha vavu chivundikiro gasket. Ndiye mutu amachotsedwa pambuyo kuchotsa injini chipika camshaft galimoto zida, kapena kungakhale yokha magiya, nthawi lamba kapena unyolo. ntchito zonse ziyenera kuchitidwa pa injini ozizira kupewa amayaka. Pamene mutu wa chipika injini chikutha pamaso kuchotsa kale zofunika kukhetsa mafuta dongosolo injini kondomu, izo ikuchitika mwa kuda spout ndi tithe kumvetsa kumasulira kuda pulagi crankcase pansi crankcase.

Kamodzi mafuta otsala, kuchotsa mutu yamphamvu ndi zinthu decompression ake limagwirira onse. Komanso unscrew ndi crankcase. Akukonzekera izo zili mwachindunji pa chipika injini pansi, choncho m'pofunika kuti kuwononga casing gasket kuchucha mosamala kuchotsa mafuta poto. Ndiye kuchotsa kapu chivindikiriro ndodozo wa ndodo popanda kuwononga zapamadzi. Unscrewed ali mwachindunji pansipa, komanso poto mafuta.

Komanso ndodo polumikiza asonkhanitsidwa pamodzi ndi pisitoni, ndiye crankshaft atachotsedwa. Tithe kumvetsa kumasulira kwake mayendedwe kwakukulu. Kenako, kuchotsa chipika injini ndi akhomere pansi engine.

Wotopetsa ikuchitika pa mphero ndi kuikira zipangizo zina zapadera mwachindunji pa makina. Ndiye mchenga izi zonse, grinded yamphamvu khoma mwachindunji.

Ndiye, nditamaliza ntchito zonse mu dongosolo lomwelo anapereka okha unsembe wa msonkhano ikuchitika ndi makokedwe wrench, womwe ndi unsembe wa polumikiza ndodo crankshaft, yamphamvu kumutu amene wokhota crosswise, kuti angakokere, kotero ntchito makokedwe wrench.

Pambuyo pa opaleshoni onse anatsanulira mafuta ndi kufufuzidwa injini psinjika
