Misconception: "ʻO kahi kaʻa me ka mīkini diesel e hoʻohaumia ʻia ma mua o ke kaʻa me ka mīkini ʻaila."
ʻO nā kaʻa Diesel kahi kokoke i ʻekolu hapaha o nā ʻauwaʻa kaʻa Farani. mooolelo Europa! Akā i nā makahiki i hala iho nei, e like me nā uku kaiapuni a me nā mea hōʻino e like me Dieselgate, ʻaʻole kaulana loa nā ʻenekini diesel. Akā, aia kahi manaʻo ākea e pili ana i ka wahie diesel: hoʻohaumia ʻo ia ma mua o ka ʻaila, ma ka mea ʻē aʻe, emi ... Vrumli deciphers i kēia mau clichés!
ʻOiaʻiʻo a hewa paha: "ʻOi aku ka haumia o kahi kaʻa me ka ʻenekini diesel ma mua o ke kaʻa me ka mīkini ʻaila"?
ʻOIAʻI, akā ...
Loaʻa i ka Diesel nā ʻano mea haumia like ʻole: nā ʻāpana liʻiliʻialaila ʻokikene naikokene (NOx) i kinoea hoʻomehana honua... No nā huna liʻiliʻi, nā kānana particulate (DPF) ke hoʻonohonoho ʻia nei i kēia manawa ma ka ʻenekini diesel hou. Pono ʻo DPF, akā ua kahiko nā ʻauwaʻa kaʻa Farani a loaʻa i nā kaʻa diesel he nui me nā kānana ʻole.
Ma ka ʻaoʻao ʻē aʻe, hoʻopuka kahi ʻenekini kakolina diesel i nā kinoea hoʻomehana hale liʻiliʻi ma mua o kahi kaʻa ʻaihue. ʻEnekini Diesel radiates a puni % o 10 CO2 ka liʻiliʻi ma mua o ka ʻenekini ʻenekini! Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka nui o ka NOx ma mua o ke kaʻa kaʻa. No kēia kumu, ʻoi aku ka haumia o ka wahie diesel ma mua o ka ʻaila.
ʻO ka ʻoiaʻiʻo, ʻaʻole like ka puhi ʻana o ka wahie diesel me ka ʻaila. Ma muli o kēia, a ʻoi aku hoʻi ma muli o ka nui o ka ea i hōʻike ʻia e kēia, ʻoi aku ka nui o ka wahie diesel i nā oxides nitrogen ʻoiai nā holomua ʻenehana i nā makahiki i hala.
No laila, hoʻokuʻu ka kaʻa diesel ma kahi o pālua ka nui o ka NOx ma mua o ke kaʻa ʻaila. Eia nō naʻe, hāʻawi nā nitrogen oxides i ka hopena o ka hale kōmahana a me ka hola 40 manawa ʻoi aku ka ʻona ma mua o ka carbon monoxide.
Ma Palani, ʻo nā kaʻa diesel he 83% o ka hoʻokuʻu ʻana o ka nitrogen oxide a me 99% o ka hoʻokuʻu ʻia ʻana o nā ʻāpana maikaʻi mai nā kaʻa kaʻa āpau. I kēlā me kēia makahiki a puni ka honua, pili nā ʻumi kaukani o ka make me NOx a me nā mea ʻala maikaʻi, ʻo ke kumu nui o ia mau mīkini diesel. ʻO ia ke kumu e kūkulu ʻia nei nā kānāwai e hōʻemi haumia o keia mau kaa.
