Pālua overhead camshaft: wehewehe

ʻO kēlā ʻōlelo i lohe ʻia e nā mea a pau ma mua, ʻo ia ka camshaft lua ma luna o ke poʻo. He ʻōlelo i ʻike ʻia ʻo "16 valves" akā ʻaʻole maopopo ka hapa nui o ka poʻe (a maikaʻi) i ke ʻano o ia ... Me ka mōʻaukala kamera e hoʻomaʻamaʻa i kāu moʻomeheu kaʻa.

Camshaft?

I ka hoʻololi like ʻana me ka crankshaft (hana ʻia ka hoʻonohonoho ʻana ma ka hāʻawi ʻana), hana ka camshaft ma ke ʻano he intake valves (kahi e komo ai ka ea + wahie) a me nā kīwaha exhaust (kahi e hele ai nā kinoea).

Eia ka enekini me

hoʻokahi wale nō

kāmela

Maʻaneʻi mākou e ʻike kokoke ana i nā kāmeʻa e hoʻokuʻu i nā kiwi i lalo, e hoʻoheheʻe ʻia i loko o ke keʻena kuni (ma ka intake a i ʻole ka exhaust).

No ka laʻana, no ka ʻenekini 4-cylinder in-line (ʻoi aku ka maikaʻi o nā mea a pau e hana ana ma Farani), hoʻokahi camshaft e lawa ai e hoʻomalu i ʻelua mau pahu no kēlā me kēia cylinder.

ʻO ka maʻamau, hoʻohana nā ʻenekini "maʻamau" i hoʻokahi pulley ('ōmaʻomaʻo LIGHT). Ma kēia ʻenekini Mazda, ʻike mākou aia ʻelua o lākou. Hōʻike kēia i ke ʻano o nā camshaft ʻelua.

Mai kēia kihi ʻē aʻe (neʻe i ka hema) hiki iā mākou ke ʻike pōkole i kekahi o nā mau camshafts (i ka poni).

ʻAʻole ʻike ʻia ka lua

no ka mea, ua ʻoki ʻia ʻo ia no laila e ʻike ʻoe i loko o ka ʻenekini (akā ʻike ʻoe i ka lua i kūpono i loko, e nānā). ʻO ka ʻōmaʻomaʻo ʻeleʻele ka crankshaft, ʻo ka uliuli kekahi o nā kiwi, a ʻo ka ʻulaʻula ke kaula manawa. E hoʻomanaʻo, ʻike wale mākou i nā pahu hoʻopau ma ʻaneʻi no ka mea ua wehe ʻia ke koena no ke kumu like me ka lua camshaft.

pālua? He aha nā pōmaikaʻi?

E hoʻomaopopo ʻoe he ʻelua ʻelua ma kahi o ka pahu camshaft pālua. A eia nā mea maikaʻi o kēia ʻenehana loea:

• Nui aʻe nā kiwi, e hiki ai i ka ʻenekini ke hanu maikaʻi.
• ʻOi aku ka maikaʻi o kēia ʻano mechanics no nā wikiwiki kiʻekiʻe, kahi kūpono no nā ʻenekini hana kiʻekiʻe (ka nui o ka ʻaila, no ka mea ʻaʻole hiki i ka wahie wai ke piʻi i nā rpms kiʻekiʻe).
• ʻO kēia hoʻonohonoho e ʻoi aku ka maʻalahi o ka hoʻolālā ʻenekini no nā mea ʻenekinia (ka hoʻolālā hoʻohele ʻana, ka wahi no nā pahu huna nui, a me nā mea ʻē aʻe, no ka mea, ʻaʻole ma luna o ka waena, hoʻokahi ma kēlā me kēia ʻaoʻao)

Ma keʻano laulā, e loaʻa i kahi ʻenekini māhoe 4 valves no ka cylinder (ʻo ka maʻamau ʻelua, ʻo ia hoʻi 8 valves no 4 cylinders, no ka mea 4 X 2 = 8 ...), akā ʻaʻole pono kēia.

Akā e akahele! ʻAʻole i manaʻo ʻia ʻo V6 a i ʻole V8 me ʻelua kāmele ʻelua. No ka hana ʻana i kēia, pono e loaʻa ʻelua mau pahu i kēlā me kēia lālani o nā cylinders.
