ʻO ka ʻaila ʻelua-stroke i ka wahie diesel. No ke aha a pehea ka nui e hoʻohui ai?
Nā mea
No ke aha e hoʻohui ai nā mea nona nā kaʻa diesel i ka aila i ka wahie?
ʻO ka nīnau koʻikoʻi a kūpono: no ke aha, ʻoiaʻiʻo, e hoʻohui i ka aila ʻelua-stroke no nā ʻenekini ʻaila i ka mīkini ʻehā-stroke, a ʻo ka diesel hoʻi? He mea maʻalahi ka pane ma ʻaneʻi: e hoʻomaikaʻi i ka lubricity o ka wahie.
ʻO ka ʻōnaehana wahie o ka mīkini diesel, me ka nānā ʻole i ka hoʻolālā a me ka hana ʻana, loaʻa mau kahi mea kiʻekiʻe. I nā ʻenekini kahiko, ʻo ia ka pauma injection. Hoʻolako ʻia nā ʻenekini hou me nā nozzles pamu, kahi i hoʻokomo pono ʻia ai ka lua plunger i loko o ke kino nozzle.
ʻO ka lua plunger he cylinder a me ka piston kūpono loa. ʻO kāna hana nui ʻo ka hana ʻana i ke kaomi nui no ka hoʻoheheʻe wahie diesel i loko o ka cylinder. A ʻo ka ʻaʻahu liʻiliʻi o ka lua e alakaʻi i ka ʻoiaʻiʻo ʻaʻole i hoʻokumu ʻia ke kaomi, a ʻo ka hāʻawi ʻana i ka wahie i nā cylinders e kū a hewa ʻole paha.
ʻO kahi mea koʻikoʻi o ka ʻōnaehana wahie ka valve injector. He ʻāpana ʻano nilala kēia i hoʻokomo pono ʻia i ka puka hiki ke laka, pono ke kū i ke kaomi nui a ʻaʻole e ʻae i ka wahie e komo i loko o ka cylinder a hiki i ka hāʻawi ʻia ʻana o kahi hōʻailona mana.
ʻO kēia mau mea a pau i hoʻouka ʻia a kiʻekiʻe-precision e lubricated wale nō e ka wahie diesel. ʻAʻole lawa nā mea lubricating o ka wahie diesel. A ʻo kahi liʻiliʻi o ka ʻaila ʻelua-stroke e hoʻomaikaʻi i ke kūlana lubrication, e hoʻolōʻihi i ke ola o nā ʻāpana ʻōnaehana wahie a me nā ʻāpana.
ʻO kaʻaila hea e koho ai?
Nui nā lula e pono e hahai i ke koho ʻana i ka aila i ʻole e hōʻino i ka ʻenekini a i ka manawa like ʻaʻole overpay.
- Mai noʻonoʻo i nā aila JASO FB a i ʻole API TB a i ʻole ma lalo. ʻO kēia mau lubricants no nā ʻenekini 2T, ʻoiai ko lākou kumukūʻai haʻahaʻa, ʻaʻole kūpono ia no ka mīkini diesel, ʻoi aku ka lako me kahi kānana particulate. ʻAʻole loaʻa nā aila FB a me TB i ka lehu haʻahaʻa haʻahaʻa no ka hana maʻamau i ka mīkini diesel a hiki ke hana i nā waihona ma nā ʻāpana o ka hui cylinder-piston a i ʻole ma ka ʻili o nā nozzles injector.
- ʻAʻole pono e kūʻai i nā aila no nā ʻenekini moku. ʻAʻole kūpono. ʻOi aku ka nui o ke kumukūʻai ma mua o nā lubricants no nā mīkini ʻelua-stroke maʻamau. A ma ke ʻano o nā waiwai lubricating, ʻaʻohe mea ʻoi aku ka maikaʻi. ʻO ke kumukūʻai kiʻekiʻe o kēia ʻāpana o nā lubricants ma muli o kā lākou waiwai biodegradation, kahi kūpono wale no ka pale ʻana i nā kino wai mai ka haumia.
- ʻO ka mea maikaʻi loa no ka hoʻohana ʻana i nā ʻenekini diesel he ʻaila o ka māhele TC e like me API a i ʻole FC e like me JASO. I kēia lā, ʻoi aku ka maʻamau o nā lubricants TC-W. Hiki ke hoʻohui pono ʻia i ka wahie diesel.
Inā he koho ma waena o ka ʻaila waʻa makamae a me ka aila haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka lawe ʻana i ka aila pipiʻi a i ʻole ka lawe ʻole ʻana.
Nā Pono
ʻEhia ka nui o ka aila XNUMX-stroke e hoʻohui i ka wahie diesel? Loaʻa nā ʻāpana no ka hui ʻana ma muli o ka ʻike o nā mea nona nā kaʻa. ʻAʻohe ʻikepili i hoʻopaʻa ʻia e ka ʻepekema a i hoʻāʻo ʻia e ka hale hana no kēia pilikia.
ʻO ka ʻāpana palekana maikaʻi loa a hōʻoiaʻiʻo ʻia ʻo ia ka manawa mai 1:400 a i 1:1000. ʻO ia, no ka 10 liters o ka wahie, hiki iā ʻoe ke hoʻohui mai 10 a 25 grams o ka aila. Hoʻonui kekahi poʻe kaʻa kaʻa i ka hoʻonui ʻana, a i ʻole ka hoʻololi ʻana, e hoʻohui i ka lubrication ʻelua-stroke liʻiliʻi.
He mea nui e hoʻomaopopo i ka nele o ka aila ʻaʻole hiki ke hāʻawi i ka hopena i makemake ʻia. A ʻo ka ʻoi aku ka mea e hoʻopili ai i ka ʻōnaehana wahie a me nā ʻāpana o ka CPG me ka soot.
Nā ʻĀina Kaona o nā kaʻa
He paʻakikī ka loaʻa ʻana o nā loiloi maikaʻi ʻole e pili ana i ka hoʻohana ʻana i ka aila ʻelua-stroke i ka wahie diesel. ʻO ke kumu, nui nā mea nona nā kaʻa e kamaʻilio e pili ana i ka mea like:
- e holo ana ka enekini me ka palupalu;
- hoʻomaka hoʻoilo maikaʻi;
- me ka hoʻohana lōʻihi ʻana i ka ʻaila ʻelua-stroke, ʻoi aku ka nui inā hoʻomaka ʻoe e hoʻohana me ka haʻahaʻa haʻahaʻa, ʻoi aku ka lōʻihi o ka ʻōnaehana wahie ma mua o ka awelika no kekahi kumu hoʻohālike kaʻa.
Hoʻomaopopo nā mea nona nā kaʻa me nā kānana particulate i ka emi ʻana o ka hoʻokumu ʻana o ka soot. ʻO ia hoʻi, emi pinepine ka hana hou ʻana.
I ka hōʻuluʻulu manaʻo, inā e hana pololei ʻia, ʻo ka hoʻohui ʻana i ka ʻaila ʻelua-stroke i ka wahie diesel e hopena maikaʻi i ka ʻōnaehana wahie o ka ʻenekini.
