He aha ke ʻano o ka OHC a he aha ka mea ʻokoʻa?
Nā mea
Mai ka ʻatikala e ʻike ʻoe i nā kaʻa i lako me nā ʻenekini camshaft overhead a ʻike i ka ʻokoʻa ma waena o DOHC a me SOHC.
overhead camshaft engine
Hōʻike ʻia nā ʻenekini OHC e kahi ʻano kūikawā o ka ʻōnaehana manawa valve kahi e kū pololei ai ka pahu pahu pahu pahu ma ke poʻo cylinder. Hoʻohana ka hapa nui o nā kaʻa hou i nā ʻenekini OHC. He maʻalahi ka hana, alakaʻi ʻia e ke kaulahao a i ʻole ke kāʻei elastic me kahi huila niho.
Ua hōʻea ʻo SOHC i kona kiʻekiʻe o ka kaulana
Ua kaulana loa nā ʻenekini SOHC i nā makahiki XNUMX. He liʻiliʻi ka pilikia, ʻoi aku ka ikaika ma mua o DOHC, akā ʻaʻole lākou i hoʻololi i ka mākeke. ʻO ka pōmaikaʻi o ka ʻōnaehana SOHC ʻo ka nele o nā mea manawa e like me nā pushrods a me nā levers laka. Mahalo i kēia, agile ka mīkini a hāʻawi i ka wikiwiki maikaʻi loa.
ʻO DOHC ka hopena kūpono?
Hōʻike ʻia ka ʻenekini DOHC ma ka loaʻa ʻana o ʻelua mau pahu kāmela a hoʻohana mau ʻia a puni ka honua e kuhikuhi i nā ʻenekini piston i loaʻa i ke poʻo ʻelua camshafts. ʻO nā ʻenekini me kēia ʻano o ka manawa valve ʻoi aku ka maikaʻi loa a ʻōlelo ʻia. Hāʻawi lākou i ka mana ʻoi aku ka liʻiliʻi o ka wahie.
ʻO ka mīkini DOHC maikaʻi a maikaʻi hoʻi, ʻo ia ke kumu i kaulana ai nā mea hana kaʻa.
