Hoʻoponopono hou a hoʻoponopono i nā mea hoʻokele diesel. ʻO nā ʻōnaehana injection maikaʻi loa
Nā mea
ʻO kekahi o nā kūlana koʻikoʻi no ka hana kūpono o ka mīkini diesel he ʻōnaehana injection pono. Me ka mīkini loea, wehewehe mākou i nā ʻōnaehana injection liʻiliʻi a hilinaʻi ʻole.
ʻOi aku ka ikaika o ka ʻenekini i ke kiʻekiʻe o ke kaomi wahie. I loko o nā ʻenekini diesel, hoʻokomo ʻia ka wahie diesel i loko o ke keʻena kuni ma ke kaomi kiʻekiʻe loa. No laila, ʻo ka ʻōnaehana injection, ʻo ia hoʻi ka pamu a me nā injectors, kahi mea nui o kēia mau mīkini.
Nā ʻōnaehana hoʻoheheʻe wahie like ʻole ma nā ʻenekini diesel
ʻO nā ʻōnaehana injection i nā ʻāpana diesel ua hoʻololi ʻia i ka ʻenehana i nā makahiki he iwakālua i hala. Mahalo iā ia, ʻaʻole ʻike hou ʻia nā abscesses kaulana i mea e pale ai i ka puhi paka. Ua lilo lākou i mea waiwai a me ka wikiwiki.
I kēia lā, hoʻohana ʻia ka hoʻoheheʻe wahie pololei ma nā ʻenekini diesel. ʻO ka ʻōnaehana maʻamau ʻo Common Rail. Ua hoʻomohala ʻia ka ʻōnaehana e Fiat i ka makahiki 90, akā ua kūʻai ʻia ka patent iā Bosch ma muli o nā kumukūʻai kiʻekiʻe. Akā ʻo ka kaʻa mua me kēia ʻōnaehana ma 1997 Alfa Romeo 156 1.9 JTD.
Ma kahi ʻōnaehana kaʻa maʻamau, ʻohi ʻia ka wahie i loko o kahi paipu maʻamau a laila puʻunaue ʻia ma lalo o ke kaomi kiʻekiʻe i nā injectors. Hāmama nā kiwi i loko o nā injectors ma muli o ka wikiwiki o ka ʻenekini. ʻO kēia ka mea e hōʻoia ai i ka hoʻohui maikaʻi ʻana o ka hui ʻana i nā cylinders a hoʻemi i ka hoʻohana wahie. Ma mua o ka hoʻokomo ʻana i ka wahie maoli, ʻo ka mea i kapa ʻia ʻo pre-injection e hoʻomaʻamaʻa mua i ke keʻena kuni. No laila, ua hoʻokō ʻia ka hoʻopau wikiwiki ʻana o ka wahie a me ka hana mālie o ka mana.
ʻElua ʻano o nā ʻōnaehana Common Rail: me nā injectors electromagnetic (i kapa ʻia ʻo Common Rail 2003th generation) a me nā injectors piezoelectric (i kapa ʻia ʻo XNUMXth generation). ʻOi aku ka hou o kēia mau mea hope, ʻoi aku ka liʻiliʻi o nā ʻāpana neʻe a me ke kaumaha māmā. Loaʻa iā lākou nā manawa hoʻololi pōkole a ʻae i ka ana ʻana wahie pololei. Mai ka XNUMX, ke hoʻololi mālie nei ka hapa nui o nā mea hana iā lākou. ʻO nā hōʻailona i hoʻohana ʻia no nā injectors solenoid me Fiat, Hyundai/KIA, Opel, Renault a me Toyota. Hoʻohana ʻia nā injectors Piezoelectric i nā mīkini hou. ʻO Mercedes, PSA hopohopo (nona o Citroen a me Peugeot), VW a me BMW.
E nānā hoʻi i nā pulu kukui ma nā ʻenekini diesel - hana, pani, nā kumu kūʻai. Alakai
ʻO kahi hopena ʻē aʻe no ka hoʻoheheʻe wahie pololei i nā ʻenekini diesel he unit injectors. Eia naʻe, ʻaʻole hoʻohana hou ʻia i nā kaʻa hou. Ua hāʻawi ka poʻe injector pump i ka ʻōnaehana Common Rail, ʻoi aku ka maikaʻi a me ka mālie. ʻAʻole hoʻohana ʻo Volkswagen, nāna i hāpai i kēia hopena.
I kekahi mau makahiki i hala aku nei, ua hoʻohana ʻo Volkswagen a me nā hōʻailona pili (Audi, SEAT, Skoda) i nā injectors. ʻO kēia kahi ʻōnaehana hoʻokomo injector (UIS). ʻO nā mea nui he mono-injectors aia ma luna pono o nā cylinders. ʻO kā lākou hana ʻo ka hana ʻana i ke kaomi kiʻekiʻe (ma luna o 2000 bar) a me ka injection o ka wahie diesel.

ʻO ka hilinaʻi o nā ʻōnaehana injection
Hoʻomaopopo ka mīkini me ka hoʻomohala ʻana o nā ʻōnaehana injection, ua emi ko lākou hilinaʻi.
- ʻO nā ʻōnaehana hoʻokele diesel pilikia liʻiliʻi ka mea i hoʻokuʻu ʻia i nā makahiki he mau makahiki a i ʻole mau makahiki i hala aku nei, kahi o ka mea nui ʻo ia ka mea hoʻoheheʻe wahie kaomi kiʻekiʻe - wahi a Marcin Geisler mai Auto-Diesel-Service mai Kobylnica kokoke i Słupsk.
ʻO kahi laʻana, ʻo nā pahu kaulana ʻo Mercedes W123 i loaʻa ʻole i ka hoʻokele. He liʻiliʻi nā ʻāpana hoʻoneʻe, a ua hana ka mīkini i kahi wahie liʻiliʻi. ʻO ka ʻaoʻao haʻahaʻa, ʻo ia ka wikiwiki o ka wikiwiki, ka hana ʻenekini walaʻau a me ka hoʻohana nui ʻana o ka diesel i hoʻohālikelike ʻia i nā powertrains o kēia lā.
ʻO nā hoʻolālā hou - me ka injection pololei - ʻaʻohe o kēia mau hemahema, akā ʻoi aku ka maʻalahi o ka maikaʻi o ka wahie. ʻO kēia ke kumu ʻoi aku ka hilinaʻi o nā ʻōnaehana me nā injectors electromagnetic ma mua o nā ʻōnaehana me nā piezoelectric.
“Ua ʻoi aku ko lākou kūpaʻa i ka wahie maikaʻi ʻole. Pau koke nā Piezoelectrics i ka wā e pili ana me ka wahie diesel i hoʻohaumia ʻia. - wehewehe ʻo Geisler - ʻO ka maikaʻi o ka wahie diesel kekahi o nā kumu nui e pili ana i ka hana o ka ʻōnaehana holoʻokoʻa. ʻO ka wahie haumia ʻaʻole i kūpono i nā kūlana ke kumu o ka pilikia.
E nana no hoi e makaala i ka wahie bapetizoia! Hoʻokaʻawale ka poʻe hoʻopunipuni i nā loiloi ma nā kikowaena
Aia kekahi mau ʻōnaehana me nā nozzles electromagnetic e haki pinepine ma mua o nā mea ʻē aʻe. ʻO kēia ka hihia, no ka laʻana, i ka Ford Mondeo III me 2.0 a me 115 hp 130 TDCi engines. a me Ford Focus I 1.8 TDCi. Ua hoʻohana nā ʻōnaehana ʻelua i nā ʻōnaehana branded Delphi.
- ʻO ke kumu o ka hana ʻino ʻana o ka pauma injection. Ma hope o ka wehe ʻana, hiki iā ʻoe ke ʻike i nā faila metala, ʻoiaʻiʻo, e hōʻino i nā nozzles, wehewehe ka mechanic. - He mea paʻakikī ke haʻi inā ua pili kēia i ka maikaʻi o ka wahie a i ʻole he hemahema ka ʻenehana hana o kēia mau pamu.
ʻO nā pilikia like ka maʻamau no Renault Megane II me kahi mīkini 1.5 dCi. Ke hana nei ka pauma Delphi ma ʻaneʻi, a ma ka ʻōnaehana wahie e ʻike pū ai mākou i nā faila metala.
Hoʻopili pū ʻo Notoriety i nā diesel Opel, kahi e hana ai ka VP44 pump. Ke holo nei kēia mau ʻenekini, i waena o nā mea ʻē aʻe, ka Opel Vectra III 2.0 DTI, Zafira I 2.0 DTI a i ʻole Astra II 2.0 DTI. E like me kā Gisler i ʻōlelo ai, ma kahi holo o 200 tausani km, hopu ka paila a koi hou i ka hana hou.
Ma ka lima 'ē aʻe, HDi engines, i hanaia e ka Farani hopohopo PSA a hoʻohana 'ia ma Citroen, Peugeot, a mai 2007 ma Ford kaʻa, pilikia me ka loaʻa 'ana i ka mua o ka 'āpana, i.е. ʻO Siemens injector.
"Hiki ke hoʻololi ʻia kahi nozzle hemahema me kahi mea i hoʻohana ʻia, akā ʻaʻole wau e ʻōlelo i kēia hopena, ʻoiai ʻoi aku ka maʻalahi," wahi a ka mechanic.

Nā kumukūʻai hoʻoponopono
ʻO ke kumukūʻai o ka hoʻoponopono ʻana i ka ʻōnaehana injection e pili ana i ke ʻano o nā injectors. ʻO ke kumukūʻai o kēia mau mea electromagnetic e pili ana i ka PLN 500 i kēlā me kēia, me ka hana, a aia i loko o ka hoʻololi ʻana i nā mea ponoʻī o ka injector.
- ʻO kēia ke kumukūʻai i ka wā e hoʻohana ai i nā ʻāpana ʻokoʻa. I ka hihia o nā mea kikoʻī e like me kahi injector, ʻoi aku ka maikaʻi o ka hoʻohana ʻole ʻana i nā mea pani, e hoʻoikaika ana ʻo Marcin Geisler.
No laila, i ka hihia o nā ʻōnaehana Denso i hoʻohana ʻia i nā mīkini Toyota, pono e hoʻololi i ka injector holoʻokoʻa, no ka mea, ʻaʻohe mea kumu ma ka mākeke.
Hiki ke hoʻololi wale ʻia nā nozzles Piezoelectric ma ke ʻano holoʻokoʻa. ʻO ke kumukūʻai ʻo PLN 1500 no kēlā me kēia ʻāpana, me ka hana.
- He mau mea hou nā mea hoʻokomo Piezoelectric a ke pale mau nei kā lākou mea hana i kā lākou mau patent. Akā ʻo kēia ka hihia me nā nozzles electromagnetic i ka wā ma mua, no laila ma hope o kekahi manawa e hāʻule paha nā kumukūʻai no ka hoʻoponopono ʻana i nā piezoelectrics, manaʻoʻiʻo kā mākou kumu.
E nānā pū i ka Gasoline, Diesel a i ʻole LPG? Ua helu mākou i ke kumukūʻai o ke kaʻa
Hoʻomaʻemaʻe i ka ʻōnaehana injection, ʻo ia hoʻi. pale ʻana
I mea e pale aku ai i nā pilikia me ka ʻōnaehana injection, pono e hoʻomaʻemaʻe mau ʻia me nā hoʻomākaukau kūikawā.
"Pono e hana i kēia i hoʻokahi manawa i ka makahiki, no ka laʻana, i ka wā e hoʻololi ai i ka aila mīkini a me nā kānana," ʻōlelo aʻe ka mechanic.
ʻO ke kumukūʻai o kēia lawelawe ma kahi o PLN 350.
