He aha ka mea hōʻeleu i ke kaʻa no?

Hoʻomanaʻo a aʻo paha ka hapa nui o nā mea kaʻa e pili ana i ke ola ʻana o ka catalytic converter i loko o ka ʻōnaehana exhaust o kahi kaʻa ke lohe wale lākou i kahi huaʻōlelo e like me "ua make kāu catalyst" mai kahi mea lawelawe. He mea maʻalahi ke hoʻoponopono ʻana i kēlā malfunction, akā ma nā ʻano like ʻole.

ʻO ka contraption, i kapa ʻia ʻo "catalyst", e lawe i ka inoa inoa o "Automotive Exhaust Catalytic Converter". ʻO kēia kahi ʻāpana o ka ʻōnaehana hoʻopau o ke kaʻa, kuleana no ka hoʻopau ʻana i nā mea ʻino i ke kanaka a me ke kaiapuni ma ke ʻano nui, e like me ka hydrocarbons unburned i loko o nā cylinders, soot, carbon monoxide CO a me ka nitrogen oxide NO, i loko o nā kinoea hoʻopau. I loko o ka catalyst, ua hoʻopau ʻia kēia mau mea a pau ma hope o ka puhi ʻana, e huli ana mai nā mea ʻoi aku ka liʻiliʻi o ka huhū mai kahi ʻano kemika: ka wai, CO2 a me ka nitrogen. Loaʻa kēia ma muli o nā hopena kemika e kū ana i mua o nā catalysts - radium, palladium a me platinum.

Hana ʻia ke kaʻina hana i ka wā e neʻe ai nā kinoea hoʻopau i loko o ka mesh mesh ceramic a i ʻole metala honeycomb i loko o ka "barela" o ka catalytic converter, i uhi ʻia me kahi huila o kēia mau metala honua laha. ʻO ka catalyst kaʻa he ʻāpana pipiʻi a ʻano pōkole. ʻOiai i ka hihia maikaʻi loa, liʻiliʻi nā mea hoʻololi e "ola" no ka ʻoi aku ma mua o 120 km. holo. Hāʻule pinepine lākou no kekahi mau kumu. Hiki i nā catalysts seramika ke wāwahi i ka wikiwiki i ka wā e hoʻokele pinepine ʻia ke kaʻa ma luna o nā puʻupuʻu koʻikoʻi. Ma muli o ka haʻalulu a me ka paʻi ʻana, ua ʻoki ʻia a ʻoki ʻia nā paia lahilahi o nā waihona meli.

I ka hanana i ka engine i pilikia i loko o ka lubrication nenoaiu, cylinder-piston hui a ignition, unburned wahie a me ka aila mai ko lakou cylinders komo i ka catalyst a sila i kona honeycombs me ka slag. Ma kahi o ka hopena like e hāʻawi ai i ke aloha o ka mea nona ke kaʻa me ke kumu ʻole a i ʻole ke kumu e kaomi ai i ka pedal kinoea i ke ala āpau i kēlā me kēia kūlana. ʻAʻole hoʻopau wale ka catalyst i hāʻule i kāna hana, akā paʻakikī pū kekahi i ka puka ʻana o nā kinoea hoʻopau mai ka mīkini. ʻO kēia, ke alakaʻi nei i ka nalowale o ka mana engine. He aha ka mea e hana ai me ka hoʻololi catalytic hemahema?

ʻO ka mea mua i hiki i ka naʻau ke hoʻololi iā ia me ka mea like, akā he mea hou wale nō. ʻO kēia ke koho pipiʻi loa. ʻO nā kumukūʻai no nā mea hoʻololi catalytic hou i hiki i kanalima tausani rubles. No laila, koho ka hapa nui o nā mea hoʻokele e hoʻololi i ka catalyst i hoʻopaʻa ʻia me kahi kumu hoʻohālike ʻole a i ʻole ke ʻano maʻamau. ʻO ka hoʻokomo ʻana i kahi catalyst e hoʻokō i nā kūlana Euro 4 i ka ikaika ma Rūsia i kēia manawa e pili ana i 10 rubles. Inā ʻaʻole hiki ke hoʻomanawanui ʻia kēia nui, a laila ma kahi o ka catalyst, ua hoʻopili ʻia kahi "barela" o kahi mea hopu ahi i loko o ka ʻāpana exhaust a i ka manawa like ua hoʻonohonoho hou ʻia ka ʻenekini. Pono ka hana hope loa i mea e hiki ai i ka mea ʻike oxygen i loko o ka ʻāpana exhaust, e hōʻailona ana ʻaʻole e hana ka catalyst, ʻaʻole ia e hoʻohālikelike i ka "lolo" uila.
