Uahi ʻenekini diesel - ʻeleʻele, keʻokeʻo a me ka uahi hina

Ua kapa ʻia ka ʻenekini hoʻopau i loko no ka mea e ʻā ana ka huila wahie-ea i loko, a, e like me kou ʻike, ʻo ka uahi a me ka lehu ka hopena o ka puhi ʻana. Inā holo maʻamau ka ʻenekini diesel a i ʻole ka ʻaila, a laila ʻaʻole nui nā huahana hoʻopau i hoʻokumu ʻia, ʻoi aku ka maikaʻi o ka uahi maʻemaʻe me ka ʻole o ka malu e puka mai i waho o ka paipu hoʻopau.

Inā ʻike mākou i ka uahi keʻokeʻo-hina a ʻeleʻele paha, a laila ua hōʻike mua kēia i nā hana ʻino o ka ʻenekini.

Hiki iā ʻoe ke heluhelu pinepine i nā ʻatikala like ʻole e pili ana i nā kumuhana automotive i hiki i nā mīkini loea ke hoʻoholo i ke kumu o ka haki ʻana e ke kala o ka exhaust. ʻO ka mea pōʻino, ʻaʻole ʻoiaʻiʻo kēia, ʻo ka waihoʻoluʻu o ka uahi e haʻi wale i ke kuhikuhi ākea o ka huli ʻana, a ʻo kahi hōʻailona holoʻokoʻa wale nō e kōkua e ʻike i ke kumu maoli o ka piʻi ʻana o ka uahi i loko o ka mīkini diesel.

Pono e ʻōlelo ʻia ʻaʻole e hoʻopaneʻe ʻia me nā diagnostics, no ka mea, ʻo ka hoʻololi ʻana i ke kala o ka exhaust e hōʻike ana i nā pilikia i ka hana ʻana o ka mīkini, ʻōnaehana wahie, turbine, pauma wahie a me nā ʻōnaehana ʻē aʻe.

ʻO ka hoʻopaʻa hou ʻana e hopena i nā kumukūʻai hoʻoponopono kiʻekiʻe i manaʻo ʻole ʻia.

Nā kūlana kūpono no ka hoʻopau ʻana i ka hui ʻana o ka wahie-ea

I mea e hana ai i nā huahana hoʻopau liʻiliʻi e like me ka hiki, pono e hoʻokō ʻia nā kūlana i loko o ka pahu cylinder o kahi mīkini diesel:

• ka maikaʻi o ka atomization o ka wahie diesel injected i loko o ka combustion keena ma o ka injector nozzles;
• hāʻawi i ka nui o ka ea i makemake ʻia;
• ua mālamaʻia ka mahana ma kahi i makemakeʻia;
• ua hana nā pistons i ke kaomi i koi ʻia no ka hoʻomehana ʻana i ka oxygen - ka lakene kaomi;
• nā kūlana no ka hui ʻana o ka wahie me ka ea.

Inā ʻaʻole i hoʻokō ʻia kekahi o kēia mau kūlana, a laila ʻaʻole e wela loa ka hui ʻana, i kēlā me kēia, aia ka ʻike kiʻekiʻe o ka lehu a me nā hydrocarbons i loko o ka exhaust.

ʻO nā kumu nui o ka hoʻonui ʻana i ka uahi i loko o ka mīkini diesel:

• hāʻawi haʻahaʻa ea;
• kuhi alakaʻi hewa;
• ʻAʻole ʻātomized pono ka wahie;
• ka wahie diesel o ka haʻahaʻa haʻahaʻa, me ka haumia a me ke kiʻekiʻe sulfur maʻiʻo, haʻahaʻa cetane helu.

Hoʻoponopono pilikia

Ua lawa pinepine e hoʻoponopono i ka pilikia pani i ka kānana ea. ʻO kahi kānana ea i hoʻopaʻa ʻia e pale i ka ea mai ke komo ʻana i ka intake manifold a hiki i ka nui.

ʻO ka uahi ʻeleʻele mai ka paipu hoʻopau e hōʻike ana ua hiki i ka manawa e hoʻololi, a i ʻole e puhi i ka kānana ea. I ka manawa like, piʻi nui ka hoʻohana ʻana i ka wahie, no ka mea, ʻaʻole i pau loa kekahi hapa o ia mea, akā hoʻokuʻu ʻia me nā kinoea pau. A inā loaʻa iā ʻoe kahi turbine, a laila hiki i ka hoʻololi ʻole ʻana o ka kānana ea ke alakaʻi i kona hāʻule ʻole, no ka mea, e hoʻopaʻa ʻia kēia mau mea i puhi ʻole ʻia i ka turbine ma ke ʻano o ka soot.

ʻO ka hoʻololi ʻana i ka kānana ea i nā hihia he nui wale ka hopena i ka pilikia. Ma hope o kekahi manawa, huli hou ka exhaust mai ʻeleʻele a aneane ʻole kala. Inā ʻaʻole kōkua kēia, pono ʻoe e nānā hohonu i ke kumu.

Me ka hāʻawi kinoea ʻoi, hiki ke hoʻololi ke kala o ka exhaust i ʻeleʻele. ʻO ka mea nui paha he hōʻike kēia no ka hoʻopaʻa ʻana o nā nozzles a ʻaʻole i hoʻopau ʻia ka hui ʻana i ka wahie. He hōʻike nō hoʻi ia o ka manawa hoʻomaka mua. I ka hihia mua, pono e hoʻomaʻemaʻe i ka injector, i ka lua o ka hihia, e nānā inā hana pololei nā mea ʻike wahie. Ma muli o ia mau pilikia, piʻi wikiwiki ka pae wela, hiki ke alakaʻi i ka puhi wikiwiki ʻana o nā pistons, nā alahaka a me nā keʻena mua.

Puhi ʻeleʻele hiki ke hōʻike i ka ʻaila mai ka turbocharger e komo i nā cylinders. Aia paha ka hewa i loko o ka turbocharger pono'ī, i ka ʻaʻahu ʻana o nā sila aʻa turbine. Hiki i ka uahi me kahi hui o ka aila ke loaʻa i kahi ʻulaʻula uliuli. ʻO ka holo lōʻihi ma luna o ia ʻenekini piha me nā pilikia nui. Hiki iā ʻoe ke hoʻoholo i ka hele ʻana o ka ʻaila i loko o ka exhaust ma ke ala maʻalahi - e nānā i ka paipu hoʻopau, ʻoi aku ka maʻemaʻe, ʻae ʻia kahi mea liʻiliʻi o ka soot. Inā ʻike ʻoe i ka slurry ʻaila, a laila komo ka ʻaila i loko o nā cylinders a pono e hana koke ʻia.

Inā iho mai ka paipu uahi hina a aia nā hāʻule i ka huki ʻana, a laila pili ka pilikia i ka paila booster, nona ke kuleana no ka hoʻolako ʻana i ka wahie mai ka pahu i ka ʻōnaehana wahie o ka hui diesel. Hiki i ka uahi polū ke hōʻike aku ʻaʻole hana pololei kekahi o nā cylinders, hoʻemi ʻia ke kaomi.

Ina mai ka paipu mai Uahi keʻokeʻo, a laila ʻo ke kumu paha ke komo ʻana o ka mea hoʻomaha i loko o nā cylinders. Hiki ke hana i ka condensation ma ka muffler, a ma kona kūlike a me ka ʻono hiki iā ʻoe ke hoʻoholo inā he antifreeze a ʻaʻole paha. I kēlā me kēia hihia, he hopena maikaʻi ka hōʻailona piha.

Ke hoʻouka nei…
