Me ka piʻi mau ʻana o nā kumukūʻai wahie a me nā lula e hoʻokuʻu ai i ka wahie, hoʻohana ikaika nā mea hana kaʻa a me nā mea hana ʻenekini i nā ʻenehana holomua like ʻole e hōʻemi i ka hoʻohana ʻana a me ka hoʻokuʻu ʻana.

Hoʻohana ka mana mau loa i ka ʻenehana hoʻoheheʻe plasma kiʻekiʻe e kāpīpī i kahi papa o ka uhi kūikawā ma ka paia o loko o ka lua cylinder, a hoʻohana i nā ʻāpana mea hoʻopili like ʻole e hoʻokō i nā koi kūikawā o ka mīkini, e like me ka maikaʻi o ka wahie a me ka lole abrasive nui. , ʻōpala a ʻino paha ma muli o ka helu hoʻihoʻi ʻana o ke kinoea exhaust (EGR).

Ua hoʻohana ʻia ka ʻenehana i nā kaʻa kaʻa, kaʻa kaʻa, nā kaʻa kaʻa a me nā ʻenekini moana, a me nā cylinder liners o nā ʻenekini wahie kinoea, nā ʻenekini mana a me nā compressors kinoea.

I kēia mau lā,Mana Zhenghengua hoʻopuka maikaʻi ʻia ka pūʻulu lua o ka diesel ola lōʻihipahu ʻenekininā laina i kahi hale hana ʻenekini diesel kaulana ma Kina.

No kēia liner cylinder lōʻihi, ʻo ka mea uhi i koho ʻia he cermet composite, nona ka pōmaikaʻi o ka hoʻohaʻahaʻa nui ʻana i ka friction a me ka ʻaʻahu ʻana o ka paia bore cylinder.

I ka manawa like, no ka mea, loaʻa i ka uhi nā ʻāpana seramika a me nā mea kūikawā, hiki ke hoʻomaikaʻi hou ʻia kona kūpaʻa ʻana i ka corrosion, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o ka liner kuʻuna iron cylinder liner.

ʻO Scania, kahi mea hana kaʻa kaʻa ʻē aʻe i ʻike ʻia, ua ʻae ʻo ia i ke kaʻina hana hoʻoheheʻe ʻana a me nā mea e like me ka mana mau ma luna o kāna ʻenekini, e ʻike ana i ka moʻolelo ʻaʻole i hoʻoponopono hou ʻia kāna kaʻa no 3 miliona mau kilomita.

I ka manawa like, no ka mea, aia i loko o ka uhi nā ʻāpana seramika a me nā mea kūikawā, hiki ke hoʻomaikaʻi hou ʻia kona kūpaʻa corrosion, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o ka hao kahiko.lina pahu.

ʻO Scania, kahi mea hana kaʻa kaʻa ʻē aʻe i ʻike ʻia, ua ʻae ʻo ia i ke kaʻina hana hoʻoheheʻe ʻana a me nā mea e like me ka mana mau ma luna o kāna ʻenekini, e ʻike ana i ka moʻolelo ʻaʻole i hoʻoponopono hou ʻia kāna kaʻa no 3 miliona mau kilomita.

I kēia manawa, ua hoʻopau ka mana Zhengheng i ka hoʻomohala ʻenehana o nā huahana e like me ka cylinder less aluminum alloy cylinder block, long-life diesel engine a me ka cylinder liner.Ua hiki i ka launa pū me nā mea hana kaʻa kaʻa kaulana kaulana a me nā mea hana ʻenekini ma ke kaʻina hoʻoheheʻe ʻana i loko o ka lua, a hiki ke hāʻawi i nā mea kūʻai aku me nā lawelawe hoʻokahi mai ka blank, machining, spraying a hiki i nā huahana honing hope.

Ka hoʻolei ʻana - pre machining - ka ʻili ʻana i ka ʻili - ke kāpī ʻana - hoʻopau - honing
