Nā mea hoʻoheheʻe ʻo Diesel. ʻO ka pilikia e hiki ke hoʻopau i ka ʻenekini

ʻO ka swirl flaps kahi hopena i hoʻohana ʻia i nā ʻenekini diesel kaʻa maʻamau. ʻO ka haunaele ea i hana ʻia i loko o ka ʻōnaehana intake ma mua pono o nā kiwi hoʻokomo e kōkua i ke kaʻina puhi ahi ma nā revs haʻahaʻa. ʻO ka hopena, ʻoi aku ka maʻemaʻe o nā kinoea hoʻopau, me ka haʻahaʻa haʻahaʻa o nā nitrogen oxides.  

ʻO ka nui o ka manaʻo, e pili ana i ka ʻoiaʻiʻo, inā ʻo nā mea āpau i loko o ka ʻenekini i maʻemaʻe loa. E like me ke kānāwai, hoʻololi nā valves i kau ʻia ma ke axis i kā lākou hoʻonohonoho ʻana ma muli o ka wikiwiki o ka ʻenekini - ma ka haʻahaʻa ua pani ʻia lākou no ka emi ʻana o ka ea i loko o nā cylinders, akā ua wili ʻia lākou e like me ke kiʻekiʻe, pono lākou e wehe. i "hanu" piha ka enekini. ʻO ka mea pōʻino, ke hana nei kēia mea hana ma lalo o nā kūlana koʻikoʻi a no laila hiki ke hāʻule. ʻO ka mea maʻamau, aia lākou i ka pale ʻana i nā kiwi ma muli o ka ʻili o ka soot a i ʻole ka hoʻokaʻawale ʻana iā lākou mai nā mea paʻa.

ʻO ka hōʻailona maʻamau o ka hāʻule ʻana o ka flap paʻa i ke kūlana ākea, ua nāwaliwali loa ka "lalo" o ka mīkini, ʻo ia hoʻi. a hiki i ka turbocharger hiki i ke kaomi hoʻonui kiʻekiʻe. Ma ka hopena hoʻonui ʻia o ka soot i nā kinoea hoʻopauA i ka wā e hoʻi ai lākou i ka intake ma o ka valve EGR, ʻoi aku ka nui o nā mea haumia i loko o ka ʻōnaehana intake. No laila, ʻo ka mea ʻohi - ua lepo - lilo i lepo ʻoi aku ka wikiwiki. 

Ke paʻa nā throttles i pani ʻia, hiki iā ʻoe ke ʻike i ka hāʻule o ka mana ma nā RPM kiʻekiʻe aʻe i ka liʻiliʻi o ka ea e huki ʻia i loko o nā cylinders. A laila e piʻi aʻe ka pae o ka soot i loko o ka ʻōnaehana. ʻO ka mea pōʻino, ʻo ka hoʻonui ʻana i ka uahi pau, me ka nānā ʻole i ka wikiwiki, loaʻa nā hopena hou aʻe ma ke ʻano o ka wikiwiki. ʻaʻahu ʻōnaehana hoʻopau (DPF kānana) a me ka turbocharger. 

E like me ke kānāwai, ʻike ʻia kēlā mau hōʻailona ma hope o ka holo ʻana ma kahi o 100-2005 km. km, ʻoiai ua ʻike hope nā mea hana mīkini i ka pilikia a hoʻomaikaʻi i nā hoʻolālā he nui ma hope o '90. ʻO ka pilikia i lilo i mea ʻino loa i ka wā i hoʻomaka ai ka hāʻule maikaʻi ʻana o nā ʻenekini diesel damper mua o nā makahiki he 47. ʻO kēia kahi kūlana i ulu pinepine i ka wā i haki ai nā flaps, ma muli o ke kau ʻana i loko o ka manifold, a hāʻule i ka hohonu i loko o ka ʻōnaehana intake, e kuʻi ana me ka valve intake, a ma hope o ka haki ʻana ua pau lākou i ka cylinder. Ma laila ʻo ia i pōʻino nui ai. ʻO nā ʻenekini i pilikia loa i kēia hanana, ʻo ia ka M57 a me M1.9 mai BMW a me ka 2.4 a me 1.9 JTD mai Fiat a me ka māhoe CDTi mai Opel.

Manaʻo ka poʻe akamai - e wehe i nā pā!

ʻOiai he mea hiki ke hoʻopaʻapaʻa ʻia kēia ma muli o ka maʻemaʻe o nā kinoea hoʻopau. ʻO nā mechanics e pili ana i nā ʻenekini diesel i kēlā me kēia lā kokoke i ka lokahi e ʻōlelo e wehe i nā flaps. Aia ia i ka hoʻohana ʻana i nā plugs ma ko lākou wahi i hoʻonohonoho ai a / a i ʻole ka hoʻopau ʻana i kā lākou hana i ka mea hoʻokele kaʻa. Hoʻomaopopo nā loea i nā diesel kaulana ʻAʻole pili ka nele o nā swirl flaps i ka hana a me nā ʻano o ka mīkini. He mea hoihoi kēia no ka mea, ʻo ka laka ʻana i nā flaps ma ke kūlana hāmama e pili ana i ka pae rpm haʻahaʻa, no laila pono ko lākou hele ʻana i kēia mau kūlana. No laila, i kekahi mau ʻenekini, a me ka wehe ʻana i nā flaps, ʻōlelo ʻia e hoʻonohonoho hou i nā palapala ʻāina i ka mea hoʻoponopono.

Eia kekahi, ʻoi aku ka maikaʻi o ka maikaʻi o nā kinoea hoʻopau (emi ka uahi) ma hope o ka wehe ʻana i nā dampers. ʻO kēia kekahi o nā mea hoʻonā i hoʻohana ʻia i nā ʻenekini diesel hou e pili ana i ka maikaʻi o ke kinoea hoʻopau, akā aia wale nō a hiki i kahi kiko (haʻahaʻa mile). I ka hala ʻana o ka manawa, ʻoi aku ka maikaʻi o nā ʻenekini me ka ʻole o nā hopena hoʻomau.

A i ʻole e pani paha?

Ma kahi o hoʻokahi ʻumi makahiki i hala aku nei, he hoʻoponopono maikaʻi kēia no ka mea ua hāʻawi wale ʻia nā intake manifold ma ke ʻano he ʻāpana ʻoihana ma kahi o PLN 2000 i kēlā me kēia. Ma nā mīkini V6, i kekahi manawa pono ʻelua e hoʻololi. I kēia lā, hāʻawi kekahi mau ʻoihana i ka hōʻiliʻili hou ʻana a i ʻole ke pani hou ʻana no kahi mau haneli zł, a ʻo nā pani pani damper (i kapa ʻia ʻo regeneration kits) ua ʻike ʻia ma ka mākeke. He liʻiliʻi ko lākou kumukūʻai, ma kahi o 100-300 zł i kēlā me kēia set.

ʻO kēia kūlana ka hana hou ʻana o nā dampers (ʻo kā lākou hana hou ʻana a i ʻole ka hoʻololi ʻana o ka ʻohi ʻohi holoʻokoʻa) ʻaʻole i ʻoi aku ka nui o ke kumukūʻai, a no laila ua kūpono ʻia. Eia nō naʻe, ʻaʻohe mea hōʻike i ka hoʻokomo ʻana i nā dampers hou ma luna o kahi mīkini me ka mile mile kiʻekiʻe, a no laila maʻamau i hoʻohaumia ʻia i loko, e hoʻomaikaʻi i ke kaʻina puhi a pēlā ka maʻemaʻe o nā kinoea pau. Eia nō naʻe, ʻoi aku ka maikaʻi o ka loaʻa ʻana o kahi mīkini hale hana piha inā no kēia kumu wale nō. E like me ka mea i manaʻo ʻia e kāna mea hoʻolālā.
