ʻEnekini Nissan VQ25HR
ʻO Nissan VQ25HR he 2.5-lita engine, ʻo ia ka muli loa o ka ʻohana HR a he V-like 6-cylinder unit. Ua ʻike ʻia i ka makahiki 2006, loaʻa iā ia kahi crankshaft a me nā koʻokoʻo hoʻohui, kahi kaʻa kaulahao manawa, a hana ʻia me ka ʻole o nā mea hoʻopiʻi hydraulic.
No laila, pono e hoʻoponopono i nā valves.
He kaʻa hou kēia me nā hiʻohiʻona hiʻohiʻona o ka moʻo:
- ʻōnaehana eVTC ma nā kumu ʻelua.
- ʻO nā lāʻau hoʻohui i hoʻonui ʻia a me kahi poloka cylinder kiʻekiʻe.
- ʻO nā piston i uhi ʻia i ka Molybdenum.
- Hoʻopili ʻia nā pushers e like me kahi ʻenehana kūikawā hydrogen-free.

Nā kaʻa me ka ʻenekini VQ25HR
Ua hoʻokomo ʻia ka ʻenekini Iapana ma nā mīkini penei:
- Nissan Fuga - mai 2006 a hiki i kēia lā.
- Nissan Skyline - mai 2006 a hiki i kēia lā.
- Infinity G25 - 2010-2012
- Infinity EX25 - 2010-2012 гг.
- Infinity M25 - 2012-2013 гг.
- Infinity Q70 - 2013-i kēia manawa
- Mitsubishi Proudia – 2012-н.в.
Ua ʻike ʻia ka kaʻa i ka makahiki 2006 a ma ka waena o 2018 ua kau ʻia ma nā hiʻohiʻona hou o ka manaʻo nui o Iapana, e hōʻoia ana i kona hilinaʻi, hana a me ka maikaʻi.
ʻO ka hana
ʻO VQ25HR kahi ʻenekini ikaika me ka torque kiʻekiʻe ma nā wikiwiki kiʻekiʻe. ʻO ia ke ʻano o ka hoʻohuli ʻana o ka kaʻa a ʻaʻole "kauo" i nā haʻahaʻa haʻahaʻa ma kahi o 2000 rpm, e like me ka nui o nā mea hoʻokele. Inā hoʻohana mau ʻoe i ka ʻenekini hoʻopau i loko me ka wikiwiki haʻahaʻa, a laila hiki ke coking, kahi e alakaʻi ai i ke ʻano o nā apo ʻaila. E ʻike ʻia kēia mai ka hoʻohana ʻana i ka aila kiʻekiʻe, no laila e aʻo ʻia e hoʻokele pono i kona pae ma hope o 100 tausani mau kilomita.
Wahi a nā mea nona, ʻaʻole kani ke kaulahao manawa ma hope o 100 tausani mau kilomita (ua ʻōlelo ka mea hana e hoʻololi iā ia ma hope o 200-250 tausani km.), A he haʻahaʻa ke kumukūʻai o ka hoʻololi ʻana, ʻo ia hoʻi kahi hoʻohui. ʻO kahi hoʻonohonoho o nā kaulahao kumu a me nā tensioners e kūʻai i 8-10 tausani rubles.
Kiʻekiʻe ka hoʻohana ʻana i ka ʻaila. I ka hoʻoilo, me ka hoʻokele koʻikoʻi, "ʻai" ka engine i 16 lita o ka wahie, a ʻoi aku paha.
He mea pono e noʻonoʻo e makemake ka ʻenekini i ka wikiwiki, a pono e untwisted ikaika, no laila ʻoi aku ka kiʻekiʻe o ka ʻai. I ke kaʻa ʻana ma ke ala nui, ʻo ka hoʻohana ʻana i ka ʻaila he 10 lita i hoʻokahi haneli, ʻo ia ka hopena i ʻae ʻia no kahi ʻāpana ikaika 2.5-lita.
Nā pilikia
ʻOiai ka hilinaʻi o ka mīkini VQ25HR a me kahi kumuwaiwai kiʻekiʻe, ua loaʻa iā ia kekahi mau pilikia:
- Ka wela nui. ʻO ka hana lōʻihi i ka wikiwiki kiʻekiʻe hiki ke alakaʻi i ka wela nui. Hiki paha kēia i ke hou ʻana i nā ʻeke poʻo cylinder. ʻO ka hopena, e komo ka antifreeze i nā keʻena ahi.
- ʻO ka wikiwiki ʻauʻau a me ka hana paʻa ʻole o ka ʻenekini hoʻopau i loko, ka mea i hoʻoiho ʻia e ka extrusion o nā gaskets channel oil. E ʻike ʻia ka hewa pili ma ka dashboard.
- Hoʻonui ʻia ka ʻaila. ʻO ke kumu o ka puhi ʻaila ma hope o nā ʻumi kaukani kilomika ʻo ka coking o ka mīkini. ʻO ka hopena, ʻaʻole e hana maikaʻi nā apo ʻaila ʻaila ma muli o ka nui o nā waihona kalapona.
- Hoʻopaʻa ʻia ma nā paia cylinder. I nā ʻenekini i hoʻohana ʻia, ʻike ʻia nā scuffs ma nā paia cylinder. ʻO ke kumu o ko lākou hiʻohiʻona ke komo ʻana i loko o nā keʻena kuni o nā ʻāpana o ka catalytic converter, e kahe ana ma laila i ka wā i pani ʻia ai nā kiwi. ʻO ia ke kumu e wehe pinepine ai nā mea nona ka ʻāpana o ka catalyst kokoke i ka puka.
No ka hōʻuluʻulu ʻana, ʻo ka VQ25HR he mīkini Kepani hilinaʻi a kiʻekiʻe loa i nele i nā kuhi hewa nui a me nā hemahema e alakaʻi ai i nā pilikia honua. No laila, me ka mālama kūpono a me ka mālama pono, e "holo" ka mīkini i 200 tausani mau kilomita me ka ʻole o ka haki.
Mahele kuai lua
Kūʻai ʻia nā mīkini ʻaelike VQ25HR ma nā kahua kūpono. ʻO kā lākou kumukūʻai e pili ana i ke kiʻekiʻe o ka lole, mileage, kūlana. Kūʻai ʻia nā ʻāpana hana ʻole "no nā ʻāpana ʻokoʻa" no 20-25 tausani rubles, hiki ke kūʻai ʻia nā mīkini hana no 45-100 tausani rubles. ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā mīkini hou i hoʻokuʻu ʻia i kēia manawa.
