Mitsubishi 4n14 mīkini
Nā mea
He mana deformed i kope ʻia mai nā ʻenekini diesel ʻEulopa, i hoʻokomo ʻia ma ka L200 pickup truck no nā makahiki ʻelua i hala. He ʻenekini kēia me nā piezo injectors a me ka turbine geometry variable.
Wehewehe koʻikoʻi
ʻO ka mīkini 4n14 ka diesel i makemake nui ʻia e nā kaʻa kaʻa Lūkini no ka lōʻihi o ka hoʻokele waiwai. Eia naʻe, ʻaʻohe mea i ʻike ʻia ma ka hale mana hou, no ka mea, ʻoi aku ka maʻalahi o ka ʻenekini a paʻa i ka wahie maikaʻi ʻole. A he aha ka mea e kahaha ai - ua hoʻoponopono ʻia ka hale holoʻokoʻa i nā kūlana Euro-5 hou. ʻO ka hopena he ʻenekini paʻakikī, ʻike ʻole ʻia ʻaʻole paha e mau me ka hoʻoponopono ʻole ʻana i ka māka kilomika 100.
I kēia mau lā, ua lilo ia i mea maʻamau i ka hana ʻana i nā ʻenekini e nānā ʻālohilohi a me ka waiwai. ʻO ka ʻoiaʻiʻo, ma hope o ka manawa hōʻoia, paʻakikī a paʻakikī ke hoʻoponopono a hana paha iā lākou. He aha ke ʻano hilinaʻi a mākou e kamaʻilio nei?
Eia hou, no ke ʻano o ke ʻano hou, ua hoʻopili ʻia kahi mīkini 8-wikiwiki me ka mīkini. E noʻonoʻo e pili ana, 8 wikiwiki - no ke aha ka nui? Hoʻopili ia i ka disposability, kekahi ʻano o nā mea kūʻai aku Kina. Wahi a nā helu helu, he mea kakaikahi ka poʻe centenarians ma waena o nā hoʻouna ʻakomi multi-wikiwiki, a ʻaʻole ia he mea kupanaha.
ʻIke ʻia ʻo 4n14 he kaʻa kaʻakaʻa, paʻakikī, pipiʻi a hilinaʻi ʻole? ʻAe, nā kaʻa i hoʻolako ʻia me ia e lilo loa ka waiwai ma hope o kēlā me kēia mālama palapala hōʻoia. A ʻo kā mākou wahie diesel hoʻi, ʻo Lūkia, nāna e pepehi i nā ʻenekini Iapana ikaika loa - 4d56, 4m40.

Nā pilikia
He mea hou ka mīkini 4n14, no laila ʻaʻole i loaʻa i nā loiloi he nui. Eia naʻe, ua hiki ke huki i kekahi mau hopena ma ke aʻo ʻana i kāna mau hiʻohiʻona hoʻolālā.
- Ua manaʻo ʻia ʻo Piezo injectors he mau ʻenehana ʻenehana i holo wikiwiki i ka honua o nā mīkini. Hana lākou i 4 mau manawa ʻoi aku ka wikiwiki ma mua o nā electromagnetic maʻamau, akā hāʻule lākou e like me ka wikiwiki.
Mea hoʻokomo piezo Diesel - ʻO ka turbine me nā geometry loli ua uhi ʻia me ka soot me ka wikiwiki, paʻa i ka wā o ka hana.
- EGR valve - ʻaʻole hiki i 50 tausani mau kilomita o ke kaʻa. ʻO ka holoi ʻana i ka valve ma hope o 15 tausani km e ʻōlelo ʻia e ka mea hana.
- ʻO Maivek - ʻo ka ʻōnaehana Mitsubishi kaao o nā ʻāpana hiki ke hana maikaʻi loa no ka manawa wale nō, no ka manawa. Ma hope o kēlā, pono ka hana kūpono i ka manawa.
- He ʻōnaehana pipiʻi ka Common Rail me nā nozzles i hoʻomalu ʻia e ka uila. Ma ke kumu, ke kenekulia hou, akā ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maʻalahi o ka injector maʻamau a ʻoi aku ka hilinaʻi.
- ʻO ke kaulahao manawa ma luna o ka ʻenekini 4m41 hou i hōʻike maopopo ʻia i nā makahiki i hala iho nei ua hoʻonui ʻia a ʻoi aku ka ʻino. ʻO kahi kumu waiwai o 70 tausani mau kilomita no kahi kaʻa metala, ʻike ʻoe, ʻaʻole paʻa loa! Eia kekahi, pono e wehe ʻia ke ʻenekini i ka wā e hoʻololi ai, no laila no ke aha lākou i kau ʻole ai i ke kāʻei.
- ʻO kahi kānana particulate i hui pū ʻia me nā catalysts he abstruse loa, ʻo ia hoʻi, ʻaʻole ia e lōʻihi.
Piezo injectors
Ua ʻōlelo maikaʻi ʻia a pololei: ʻo ka mea maikaʻi no ka ʻenekinia he ʻino ia no ka locksmith. ʻO kēia wale nō e pili ana i nā piezo injectors, ʻo ka hoʻoponopono ʻana he mea weliweli maoli ia no nā limahana hana kaʻa. I kēia lā, hoʻohana nui ʻia nā piezo injectors i nā ʻōnaehana Common Rail ma nā mīkini diesel. Ke koi ʻia nei lākou e nā mea hoʻolālā i hoʻohana i nā mea hana ʻenehana kiʻekiʻe no ka hoʻoponopono maikaʻi ʻana i ka ʻenekini puhi ahi. Akā, hoʻopau nā mechanics a me nā mea nona nā kaʻa me kahi bouquet o nā pilikia kālā a me nā ʻenehana paʻakikī e hoʻoponopono.
Ma kahi o kahi magnet uila me ka neʻe ʻana, ua hāʻawi ʻia ka piezo injector me kahi mea kūikawā i ke ʻano o ke kolamu square. I nā huaʻōlelo ʻē aʻe, he hoʻonohonoho kēia o nā papa seramika i hoʻopaʻa ʻia ma luna o kēlā me kēia a kūʻai ʻia, kahi, ma lalo o ka mana o kēia manawa, loaʻa kahi hopena piezoelectric. ʻO ka hoʻolālā o ka piezo injector ke ao holoʻokoʻa, hiki iā ia ke hoʻololi i kona lōʻihi i ka manawa pōkole, a laila e hana ana i ka valve control. Ke hoʻohālikelikeʻia me kahi mea hoʻokomo maʻamau,ʻo kēia ka hoʻonuiʻana i ka wikiwiki o ka paneʻana i ka 0,4 ms,ʻoi aku ka ikaika ma ka valve a me ka pololei o kaʻokiʻana i ka lako wahie. Ma kahi huaʻōlelo, hoʻokahi wale nō mea hoʻohui.
I kēia manawa no nā cons. Mai ka manaʻo o ka lawelawe, ʻo ka pilikia nui o nā piezo injectors ka paʻakikī kiʻekiʻe o kā lākou hoʻoponopono. Eia kekahi, he mau mea koʻikoʻi loa kēia e pane ana i ka emi iki o ka maikaʻi o ka wahie diesel. ʻO ka ninini pinepine ʻana i ka wahie maikaʻi me kahi kiʻekiʻe o ka hoʻomaʻemaʻe ʻana i nā keʻena kinoea ma Rūsia ʻaʻole maoli maoli, no laila, ma hope o ʻelua mau tausani kilomita, hoʻoponopono ʻia nā kaʻa me ia ʻōnaehana.
Ke noʻonoʻo ʻia nei ke koho pani holoʻokoʻa. Eia nō naʻe, ʻaʻohe mea maikaʻi no ka poʻe Lūkini - he kumukūʻai nui nā piezo injectors. ʻO ka loulou pili loa i ka ʻōnaehana piezo injector ʻo ia ka valve control, ʻo ka hiki ʻole ke hoʻoweliweli e hōʻino i ka injector holoʻokoʻa.
Turbine me ka hoʻololi ʻana o ka geometric
ʻO ka ʻokoʻa ma waena o ka turbine maʻamau a me kahi ʻano ʻokoʻa me ka geometry hoʻololi, ʻo ia, ke hoʻohālikelike ʻia me ka mea maʻamau, ua hoʻololi ʻia ka ʻāpana ma ka puka huila ma aneʻi. Hana ʻia kēia no ke kumu hoʻokahi o ka hoʻonui ʻana i ka mana o ka turbine no kahi ukana i hāʻawi ʻia.
He kiʻekiʻe kiʻekiʻe loa ka ʻenekini me ia turbine. Hoʻomalu ʻia ka Supercharging e kahi kaʻa, kahi mea hoʻoponopono vacuum a me kahi kaʻa stepper.
Ma ke kumu, ua manaʻo ʻia ka turbine geometry variable kekahi o nā ʻōnaehana turbocharging maikaʻi loa i ka pae. ʻOi aku ka maikaʻi ma mua o ka twinscroll, turbo a me ka turbine hoʻokahi, kokoke e like me ka turbine uila a me ka twinscroll variable. Akā, eia hou, hele mua ka maikaʻi o ka wahie diesel - hoʻopau koke ka wahie ʻilihune i kēia ʻano turbine.
Kānana pākuʻi
Ua kau ʻia ka mea ma luna o nā mīkini diesel no ka manawa lōʻihi. Hoʻolālā ʻia e hoʻomaʻemaʻe i ka lewa o ka soot keu, ka mea nui i ka wahie diesel. ʻO ka hoʻokomo ʻana i kahi kānana particulate ma kahi Mitsubishi 4n14 e like me ka hoʻomaikaʻi ʻana i ka poʻe kaiapuni, no ka mea, ʻo lākou ka mea i hele mai me kēia ʻano.
ʻO ka ʻoiaʻiʻo, ʻo ka kānana particulate kahi mea pani no ka catalyst a i ʻole kāna hoʻohui. He ʻāpana ʻokoʻa ia i waiho ʻia ma hope o ka catalyst a i hui pū ʻia me ia - e like me nā ʻenekini 4n14 a me Volkswagen.
ʻIke loa, mai ka wahie maikaʻi ʻole, e hoʻopaʻa koke ʻia ka kānana particulate, kahi e hana ai i kahi pale kino i nā kinoea a hoʻemi i ka mana mīkini.

Ka hopena e pili ana i ka mīkini 4n14: hou, ʻenehana holomua, e hoʻokō i nā kūlana Euro-5. Akā paʻakikī ke kapa ʻia he mea hilinaʻi, mālama ʻia a maʻalahi.
