Li-valve lifters tse senyehileng - hobaneng ts'ebetso ea tsona e le bohlokoa hakaale?

Li-pushers tse senyehileng - matšoao a ho se sebetse hantle

Lintho tse phahamisang li-valve ke tse ling tsa likarolo tsa enjene tse phethang karolo ea bohlokoa ho cheseng ha motsoako oa mafura a moea. Ba kenya li-valve, ho lumella mafura le moea hore li kene ka har'a silinda, 'me ka mor'a moo ho ntšoa likhase tsa ho tsoa tse setseng ho tloha ts'ebetsong.

Potoloho ea mosebetsi oa li-valve e tlameha ho ts'oana le potoloho ea mosebetsi oa piston. Ke ka lebaka leo li khannoang ke li-lobe tsa camshaft tse potolohang. Sistimi ena e hokahantsoe ka botlalo fekthering, empa e ka sitisoa nakong ea ts'ebetso ea enjene. Bothata ke hore seo ho thoeng ke "valve clearance", ke hore, sebaka se lekanang pakeng tsa camshaft cam le sebaka sa tappet. Lekhalo le tlameha ho bolokoa ka lebaka la thepa ea 'mele ea tšepe, e ntseng e eketseha ka mocheso o phahameng, ho eketsa molumo oa eona.

Ho tlosoa ha li-valve ka tsela e fosahetseng ho ka ba le liphello tse peli:

• Ha e le tlase haholo, e ka etsa hore li-valve li se ke tsa koala, e leng se bolelang hore enjene e tla lahleheloa ke khatello (ts'ebetso e sa lekanyetsoang ea yuniti, ho hloka matla, joalo-joalo). Ho boetse ho na le ho apara ka potlako ho li-valve, tse lahleheloang ke ho kopana le litulo tsa valve nakong ea potoloho ea ts'ebetso.
• Ha e le khōlō haholo, e ka lebisa ho apara ka potlako ha sefofane sa valve, ha ho roaloa ha likarolo tse ling tsa tsamaiso ea khase (li-cams, levers, shaft) ho potlakisa. Haeba tumello ea valve e le kholo haholo, ts'ebetso ea enjene e tsamaisana le ho kokota ha tšepe (e nyamela ha mocheso oa yuniti o phahama, ha likarolo tsa tšepe li eketseha ka molumo).

Li-pushers tse senyehileng - liphello tsa ho se tsotelle

Bongata ba lienjineri tsa sejoale-joale tsa likoloi li sebelisa li-valve tsa hydraulic tse ikamahanyang le li-valve ka bo eona. Ka khopolo, mokhanni oa koloi ka tsela eo o tlosa tlhokahalo ea ho laola le ho beha ka letsoho sebaka sa tumello ea valve. Leha ho le joalo, lipompo tsa hydraulic li hloka oli ea enjine e nang le liparamente tse nepahetseng hore li sebetse hantle. Ha e e-ba e teteaneng haholo kapa e silafetse, masoba a tappet a ka koaloa, a etsa hore valve e se ke ea koala. Enjene e sebetsang ka tsela ena e tla etsa lerata le ikhethang, 'me litulo tsa valve li ka cha ha nako e ntse e ea.

Likoloi tse nang le li-valve tsa mochini li hloka ho lokisoa nako le nako joalo ka ha moetsi oa enjine a khothaletsoa. Tokiso e bonolo ka mochini, empa ho khothaletsoa ho e etsa ka har'a workshop. Ho lekanya lekhalo, ho sebelisoa se bitsoang feeler gauge, 'me boholo bo nepahetseng ba lekhalo bo finyelloa ka ho lokisa li-screws le ho sebelisa li-washer.

Ka tloaelo, linako tsa ho lokisa lekhalo ho li-pusher tsa mochini li tloha ho mashome a lik'hilomithara tse likete tse lekholo. Leha ho le joalo, litlhahiso tsa fektheri li hloka ho ntlafatsoa haeba ho etsoa qeto ea ho kenya tsamaiso ea khase koloing. Joale ho hlokahala ho hlahloba le ho lokisa papali khafetsa. Lienjine tsa LPG li pepesehetse mocheso o phahameng. Ho phaella moo, ts'ebetso ea ho chesa khase ka boeona e telele ho feta tabeng ea ho chesa peterole. Sena se bolela mojaro o moholo le o molelele oa mocheso holim'a li-valve le litulo tsa li-valve. Likhao tsa ho lokisa lekhalo bakeng sa likoloi tse nang le khase li ka ba lik'hilomithara tse 30-40. km.

Ho haella ha litokiso tsa khafetsa ho enjine efe kapa efe e nang le li-valve tsa mochini ho tla lebisa ho senyeha ho hoholo ha likarolo tsa kamore ea enjene. Leha ho le joalo, esita le lienjineng tse 'nileng tsa lokisoa khafetsa, li- valve lifting li ka 'na tsa hloka ho nkeloa sebaka ke tse ling ha nako e ntse e ea.

Ho fetola li-valve lifters - ho hlokahala neng?

Mokhoa oa ho khutlisa o ipapisitse le moralo oa enjene, 'me mefuta ea li-valve lifter le eona ea fapana. Hangata, ka mor'a ho tlosa sekoahelo sa valve, ho hlokahala ho tlosa camshaft e le hore li-pushrods li ka tlosoa 'me li nkeloe sebaka ke tse ncha. Lienjiniere tse ling, ka mor'a ho nkeloa sebaka, ho tla hlokahala ho lokisa li-pushers tse ncha, ho tse ling li lokela ho tlatsoa ka oli, ho tse ling, mehato e joalo ha e sebetse.

Ho bohlokoa ho nkela li-gaskets tsohle sebaka ka tse ncha nakong ea tokiso le ho hlahloba boemo ba likarolo tse ling tsa nako. Haeba enjene e 'nile ea sebelisoa ka nako e itseng ka li-valve tse sa nepahalang, li-lobe tsa camshaft li ka' na tsa apesoa. Hape ke habohlokoa ho sheba boemo ba shaft ka boeona.
