Enjene ea Mitsubishi 6A12
Tse ka hare
E qapiloe ke lihahi tsa enjine tsa Majapane tsa Mitsubishi Motors Corporation (MMC), enjene ea 6A12 e ntlafalitsoe khafetsa. Ho sa tsotellehe liphetoho tse kholo, index e ile ea lula e le teng.
tlhaloso
Sesebelisoa sa matla sa 6A12 se hlahisitsoe ho tloha 1992 ho isa 2010. Ke enjene ea peterole e nang le sebōpeho sa V e nang le li-cylinder tse tšeletseng e nang le boholo ba lilithara tse 2,0 le matla a 145-200 hp.
E kentsoe likoloing tsa MMC, Proton automakers (e entsoeng Malaysia):
The cylinder block ea liphetoho tsohle tsa enjene ke tšepe ea tšepe.
Hlooho ea silinda e entsoe ka motsoako oa aluminium. Mefuteng e fapaneng ea lienjine, ho ne ho beoa camshaft e le 'ngoe kapa tse peli hloohong. Camshaft e ne e le holim'a litšehetso tse 'nè (SOHC), kapa tse hlano (DOHC). Likamore tse tukang tsa mofuta oa tente.
Li-valve tsa exhaust tsa lienjine tsa DOHC le DOHC-MIVEC li tletse sodium.
Tšepe ea crankshaft, e entsoeng. E lutse holim'a litšiea tse 'nè.
Piston ke e tloaelehileng, e entsoeng ka motsoako oa aluminium, e nang le li-compress tse peli le mehele e le 'ngoe ea oli.
Sistimi ea ho tlotsa e nang le tlhoekiso ea oli e felletseng le phepelo ea eona tlas'a khatello ea li-unit tsa ho tlotsa.
Sistimi e pholileng e koetsoeng ka phepelo ea sepholi e qobelloang.
Sistimi ea ho khantša bakeng sa lienjine tsa SOHC ha e kopane le mofani oa thepa, e nang le khoele e le 'ngoe ea ho khantša. Lienjineri tsa DOHC li entsoe ntle le morekisi.
Mefuta eohle ea likarolo tsa motlakase e na le sistimi e qobelloang ea moea ea crankcase e thibelang ho lokolloa ha likhase tse tsoang ho eona.
Lienjineri tse tukang ka hare tse nang le sistimi e feto-fetohang ea nako ea li-valve MIVEC (sistimi ea taolo ea li-valve tsa elektroniki ho latela lebelo la crankshaft) e eketsehile matla le litaba tse tlase tsa lintho tse kotsi likhase tse tsoang. Ho feta moo, ho na le ho boloka mafura. U ka shebella video mabapi le hore na sistimi e sebetsa joang.

Ho tšepahala
Ho ea ka boitsebiso bo fumanehang, li-motors tsa 6A12, tse itšetlehileng ka melao ea tlhokomelo le ts'ebetso ea tsona, li hlōla habonolo moeli oa mohloli oa lik'hilomithara tse likete tse 400. Ho tšepahala ha yuniti ea matla ho itšetlehile ka boikutlo ho eona ho tloha ho mokhanni.
Litaelong tsa ts'ebetso ea koloi, moetsi o ile a senola ka botlalo litaba tsohle tsa tlhokomelo ea enjene. Empa mona ntlha e le 'ngoe ea bohlokoa e tlameha ho nkoa - bakeng sa Russia, litlhoko tsa tlhokomelo li lokela ho fetoloa hanyenyane. Ka ho khetheha, nako ea ho sebetsa pakeng tsa tlhokomelo e latelang e fokotsehile. Sena se bakoa ke ho se be le mafura a boleng bo holimo le lisebelisoa le litsela tse fapaneng le tsa Majapane.
Ka mohlala, ha u sebelisa mochine o tukang ka hare ho maemo a thata, ho kgothaletswa ho fetola oli ka mor'a lik'hilomithara tse 5000 XNUMX tsa koloi. Ho ntlafatsa ho tšepahala ha enjene, sebaka sena se tla tlameha ho fokotsoa. Kapa tšela oli ea boleng ba Majapane ka har'a sistimi. Ho hloleha ho ikamahanya le maemo ana ho tla tlisa phetoho e haufi haholo.
Setho sa Fora Marat Dulatbaev se ngola se latelang mabapi le ho ts'epahala (mokhoa oa mongoli o bolokiloe):
Kahoo, hoa khoneha ho bua ka kholiseho ka botšepehi bo phahameng ba yuniti ka tlhokomelo ea eona e nepahetseng.
Mabala a fokolang
Motlakase oa 6A12 o na le mefokolo e mengata, liphello tse mpe tsa tsona li ka fokotsoa habonolo. Kotsi e kholo ka ho fetisisa e bakoa ke ho fokotseha ha khatello ea oli. Ketsahalo ena hangata e etsa hore li-insert li fetohe. Tlhokomelo ea kamehla ho latela litlhahiso tsohle tsa moetsi ke senotlolo sa ts'ebetso e phethahetseng ea enjene.
Sesebelisoa sa lebanta la nako e tlase (lik'hilomithara tse likete tse 90). Ha e senngoa, ho kobeha ha li-valve ho ke ke ha qojoa. Ho fetola lebanta ka mor'a lik'hilomithara tse likete tse 75-80 ho tla felisa ntlha ena e fokolang.
Lisebelisoa tsa li-hydraulic li felloa ke matla ka potlako. Lebaka le ka sehloohong ke tšebeliso ea oli ea boleng bo tlaase. Li-unit tsa matla tsa 6A12 tsa liphetoho tsohle li nkuoa e le "omnivorous" ho latela mafura, empa li hloka haholo boleng ba oli. Ho sebelisa limaraka tse tlase ho lebisa ho lokisoeng ha enjene e theko e boima.
Tlhokomelo
The maintainability ea enjene molemo. Inthaneteng, u ka fumana boitsebiso bo bongata tabeng ena. Basebelisi ba liforamu melaetsa ea bona ba ngola tlhaloso e qaqileng ea mehato ea ho lokisa enjene ka matsoho a bona. Ho hlakisa, hokela senepe.
Likarolo le tsona ha se bothata bo boholo. Mabenkeleng a khethehileng a marang-rang u ka fumana karolo leha e le efe kapa kopano. Tokiso ea mofuta ona, joalo ka tšebeliso ea likarolo tsa enjene ea bafani, e se e atile.
Empa khetho e ntle ka ho fetisisa ea ho rarolla bothata ba tokiso ke ho beha ts'ebetsong ea eona ho litsebi tsa litšebeletso tse khethehileng tsa koloi.
Liphetoho tsohle tsa enjine ea Mitsubishi li ne li tšepahala ebile li tšoarella. Empa e batla haholo boleng ba mafura le mafura, haholo oli.
