Ịghọta Valve Gear na mmetụta ya na mmepụta engine

Gear Valve bụ otu n'ime ihe kachasị mkpa nke injin, ọkachasị n'ịchọpụta mmepụta ya.Ọ bụ ya na-ahụ maka ịhazi oke mmanụ na ikuku na-abanye ma na-apụ n'ọnụ ụlọ ọkụ nke injin.Ngwa valvụ ahụ nwere ọtụtụ ihe jikọrọ ọnụ, gụnyere camshaft, tappets, pushrods, rockers, na valves, ha niile na-arụkọ ọrụ ọnụ iji chịkwaa arụmọrụ nke injin ahụ.

Otu isi ihe dị mkpa mgbe ọ na-abịakwute gia valvụ bụ ọnụ ọgụgụ ebuli na ogologo oge nke oghere valvụ ahụ.Ebuli elu na-ezo aka n'ebe dị anya nke valvụ na-emepe mgbe oge ahụ bụ ogologo oge nke valve na-emeghe.Ọnụọgụ nke ebuli na ogologo oge na-ekpebi oke ikuku na mmanụ injin nwere ike ibu, nke na-emetụta mmepụta ya n'ikpeazụ.

Enwere ụdị gia valvụ dị iche iche a na-eji na injin, gụnyere cam-overhead (SOHC), cam dual-overhead (DOHC), na pushrod.Nke ọ bụla n'ime ngwa valvụ ndị a nwere uru na ihe ndọghachi azụ ya, na ịghọta ọdịiche ha nwere ike inyere gị aka ịhọrọ nke ziri ezi maka ebumnuche injin gị.

Ngwa valvụ SOHC, dịka ọmụmaatụ, dị mfe ma nwee ike inye ezigbo ike, torque na akụ na ụba mmanụ.DOHC valve gear, n'aka nke ọzọ, dị mgbagwoju anya mana ọ nwere ike imeziwanye arụmọrụ engine site na ịnweta ikuku na ikpochapụ ka mma, karịsịa na RPM dị elu.Ngwá ọrụ valvụ Pushrod, nke na-ejikọta ya na injin ndị ochie, na-enwekarị ntụgharị dị ala ma mee ya maka ike karịa karịa mmepụta ike inyinya.

Mgbe a bịara n'ịkwalite mmepụta engine site na iji valve gear, ebumnuche bụ isi bụ iji nweta oke ikuku nwere ike ime.Nke a bụ n'ihi na ikuku ikuku dị mkpa n'ịmepụta usoro combustion nke na-emepụta ike.Otu ụzọ isi mee ka ikuku na-eruwanye elu bụ site na iji valvụ dị elu ma ọ bụ ogologo oge, na-ekwe ka injin ahụ nwetakwuo mmanụ ọkụ na ikuku.Agbanyeghị, usoro a nwere oke ya, nsonaazụ ikpeazụ dabere na ihe ndị dị ka nchụpụ injin, imepụta isi cylinder, na arụmọrụ ọkụ.

Ụzọ ọzọ isi kwalite mmepụta engine site na iji valve gear bụ site n'ịkwalite oge valvụ iji nweta uru nke elu nke engine na ike ịnyịnya.Ị nwere ike nweta nke a site na ịnwale profaịlụ cam dị iche iche, nke na-akọwa mgbe na ole valves meghere ma mechie.Ihe mgbaru ọsọ ebe a bụ iji hụ na valvụ ndị ahụ meghere nke ọma n'oge usoro ọkụ ọkụ, na-enye ohere maka mmanụ ọkụ na ngwakọta ikuku na-enye ike kachasị ike.

Na mmechi, gia valvụ bụ ihe dị mkpa na injin ọ bụla, na ịghọta ka o si emetụta mmepụta injin nwere ike inyere gị aka ịkwalite arụmọrụ injin gị.Gbaa mbọ hụ na ịhọrọ gia valvụ ziri ezi maka ebumnuche injin gị wee nwalee oge valvụ iji nweta oke ikuku na mmepụta ike.N'ikpeazụ, na-echeba nchekwa na ntụkwasị obi mgbe niile mgbe ị na-ebuli arụmọrụ engine gị wee kpọtụrụ ọkachamara ma ọ bụrụ na ị maghị na ịme mgbanwe ọ bụla na valvụ engine gị.
