Nā pilikia a me ka hoʻoponopono ʻana i nā pilikia

Needle injectors… I nā ʻenekini hou, hoʻohana nui ʻia nā ʻenekini i loko o nā ʻenekini ʻaila, a ʻoi aku ka nui ma GDI (gaso direct injection). E like me kā mākou i kūkākūkā ai ma nā ʻatikala mua, GDI atomizes a atomizes wahie pololei i loko o ka combustion keʻena, ma luna o ka piston. Ma muli o ka hoʻonohonoho ʻana o ka pintal, hoʻokumu ʻia nā waihona kalapona pintal ma ka cone pintal, kahi e hoʻopilikia ai i ke ʻano hoʻoheheʻe. Ke piʻi aʻe nei ke kūkulu ʻana, ʻo ka hāʻawi like ʻole ʻana o ka jet e hopena i kahi kuni like ʻole e hoʻomohala ʻia i ke kī ʻana a i ʻole ke kani ʻana...a hiki ke hana i kahi wela ma ka piston a i ʻole, i nā hihia koʻikoʻi, hoʻoheheʻe i ka lua o ka piston. ʻO ka mea pōʻino, hoʻoponopono ʻia kēia ʻano (malia paha) ma ka hoʻopili ʻana i kahi mea hoʻohui "hoʻomaʻemaʻe" wahie, hoʻomaʻemaʻe mechanically i ka ʻōnaehana injection me nā mea hana kūikawā a me kahi hopena koʻikoʻi, a i ʻole ka wehe ʻana i nā injectors no ka lawelawe a i ʻole ke pani.

ʻO nā injectors multi-hole ka mea nui i hoʻohana ʻia i nā mīkini diesel. ʻO ka pilikia nui e kū nei i kēlā me kēia mīkini diesel hou i kēia lā, ʻo ia ka maikaʻi a me ka maʻemaʻe o ka wahie. E like me ka mea i ʻōlelo ʻia ma mua, hiki i nā ʻōnaehana Common Rail hou ke kaomi a hiki i 30,000 psi. I mea e hoʻokō ai i kēlā mau koi kiʻekiʻe, ʻoi aku ka paʻa o ka ʻae ʻana o loko ma mua o nā mana o nā nozzles mua (ʻo kekahi mau ʻae ʻana i ka rotational he 2 microns). No ka mea, ʻo ka wahie wale nō ka lubricant no nā injectors a no laila nā injectors, pono kahi wahie maʻemaʻe. ʻOiai inā hoʻololi ʻoe i nā kānana i ka manawa kūpono, ʻo kahi hapa o ka pilikia ka lako wahie ... kokoke i nā pahu wai lalo āpau i loaʻa nā mea haumia ( lepo, wai a i ʻole nā ​​​​algae) i kau ʻia ma lalo o ka pahu. ʻAʻole pono ʻoe e hoʻopiha i ka wahie inā ʻike ʻoe i kahi kaʻa wahie e hāʻawi ana i ka wahie (no ka mea, pili ka wikiwiki o ka wahie e komo mai ana i ka mea i loko o ka pahu) - ʻo ka pilikia ʻo ka haʻalele wale ʻana o ka kaʻa a ʻaʻole ʻoe i ʻike!!

He pilikia nui ka wai i ka wahie no ka mea e hoʻokiʻekiʻe ka wai i ka paila o ka wahie, akā ʻoi aku ka maikaʻi o ka hopena i ka lubricity o ka wahie i koʻikoʻi ... ʻoi aku ka nui o ka sulfur i loaʻa ma ke ʻano he lubricant i wehe ʻia e ka EPA kauoha. . ʻO ka wai i loko o ka wahie ke kumu nui o ka hāʻule ʻana o ka injector tip. Inā loaʻa iā ʻoe kāu mau pahu mālama ma luna o ka ʻāina, ʻo ka condensate i hana ʻia i loko o ka pahu ma luna o ka laina wahie (ʻoi aku ka wikiwiki o ka hoʻololi ʻana i nā mahana) e hana i nā kulu a hele pololei i lalo o ka pahu. ʻO ka mālama ʻana i kēia mau pahu waihona e hōʻemi i kēia pilikia… Manaʻo ʻia e hoʻopili hou i ka pahu waihona inā loaʻa iā ʻoe ka meaʻai ʻumekaumaha ma lalo o ka pahu.

He pilikia hoʻi ka wahie lepo a i ʻole algae me nā ʻōnaehana kiʻekiʻe o kēia wā. Hiki iā ʻoe ke haʻi maʻamau inā pilikia ka hoʻohaumia ʻana ma ka nānā ʻana ... ua hoʻopili ʻia kekahi mau kiʻi i ka leka.

ʻO kekahi pilikia a mākou e kū nei ma ʻAmelika ʻĀkau, ʻo ia ka maikaʻi maoli a i ʻole ka flammability o ka wahie ponoʻī. ʻO ka helu cetane kahi ana o kēia. Aia ka wahie Diesel ma mua o 100 mau ʻāpana e pili ana i ka helu cetane (e like me ka helu octane o ka ʻaila).

Ma ʻAmelika ʻĀkau, ʻo ka helu cetane liʻiliʻi he 40... ma ʻEulopa, ʻo ka liʻiliʻi loa he 51. ʻOi aku ka ʻino ma mua o ke kani ʻana no ka mea he pālākiō logarithmic. ʻO ka mea wale nō e hiki ke hana, ʻo ia ka hoʻohana ʻana i kahi mea hoʻohui e hoʻomaikaʻi i ka helu cetane a me ka lubricity. Hiki ke loa'a iā lākou…e noho ka'awale mai ka po'e me ka wai'ona...e ho'ohana wale 'ia ma ke 'ano he hopena hope loa ke pa'a ka laina wahie a i 'ole ka paraffin. Na ka waiʻona e hoʻopau i ka lubricity o ka wahie, e hopu ai ka pamu a i ʻole nā ​​mea hoʻokomo.
