Enekinia 2TR-FE
ʻIke nā kaʻa kaʻa i ka mīkini 2TR-FE mai ka Toyota Prado SUV, ma lalo o ka puʻupuʻu i hoʻokomo ʻia mai ka makahiki 2006. Ma kekahi mau hiʻohiʻona ʻē aʻe, e like me Hilux, ua hoʻokomo ʻia ka mīkini mai ka makahiki 2004.
hōʻikeʻano
ʻO ka 2TR-FE ka mīkini ʻehā pahu nui loa o Toyota. ʻO ka nui pololei he 2693 cubes, akā ʻo ka lālani "ʻehā" i hōʻike ʻia he 2.7. ʻAʻole like me ka mīkini 3RZ-FE o ka nui like, ua hoʻolako ʻia ka ʻenekini me kahi ʻōnaehana hoʻololi valve timing Toyota, i ka hihia o Land Cruiser Prado 120 a me Prado 150, hiki iā ʻoe ke loaʻa 163 hp ma ka hopena. ma 5200 rpm crankshaft.
Ka Toyota 2TR-FE engine ua lako me eha kiwikā no ka cylinder, i hoʻomaikaʻi combustion keena scavenging a hana e hoonui i ka mana, no ka mea, o ka ea kahe mau neʻe i loko o kekahi aoao - mai ka intake kiwikā a hiki i ka exhaust. Hoʻomaʻamaʻa ʻia ka hilinaʻi ʻo Toyota kaʻao e ka holo kaulahao manawa. Ua lako ʻia ʻo 2TR-FE vvt-i me kahi ʻōnaehana injection distributor.
Geometry a me nā hiʻohiʻona
E like me nā ʻenekini Toyota ʻē aʻe, ua like ke anawaena o nā pahu kaʻa me ka piston stroke. ʻO nā ʻāpana ʻelua ma 2TR-FE he 95 mm. ʻO ka mana kiʻekiʻe loa i hoʻouna ʻia i nā huila, ma muli o ke kumu hoʻohālike, ʻokoʻa mai 151 a 163 horsepower. Loaʻa ka mana kiʻekiʻe loa mai ka Prado, nona ka torque he 246 N.M. ʻO ka mana kūikawā o ka 2TR-FE i kau ʻia ma ka Land Cruiser Prado 120 he 10.98 kg no 1 horsepower. He 9.6: 1 ka lākiō ho'opi'i o ka mīkini, hiki i kēia mau lākiō ho'opi'i ke ho'ohana i ka 'aila 92nd, akā 'oi aku ka maika'i o ka ho'opiha 'ana i ka 95th.

ʻO nā hiʻohiʻona mana o ka 2TR-FE e hāʻawi i kahi SUV koʻikoʻi i ka agility i ke kaʻa o ke kūlanakauhale, akā ma ke ala nui, inā pono ʻoe e hopu mai ka wikiwiki o 120 km, ʻaʻole lawa ka mana. He mea koʻikoʻi loa ka hoʻololi ʻaila i ka manawa no kēlā me kēia ʻenekini puhi ahi. Hoʻolālā ʻia ka mīkini 2TR-FE no ka ʻaila synthetic 5w30, pono e hoʻololi ʻia i kēlā me kēia 10 km. No ka 2TR-FE, ua manaʻo ʻia ka hoʻohana ʻana i ka aila o 300 ml no 1 km. I ka holo ʻana o ka ʻenekini kiʻekiʻe, pau ka ʻaila. He 000 mm ka lua wela o ka mīkini.
Me ka hana kūpono, ʻo ke kumu waiwai ma mua o ka hōʻeha ʻana ma kahi o 500 - 600 tausani km, akā me ka holo ʻana o 250 km, pono e hoʻololi ʻia nā apo. ʻO ia hoʻi, i ka manawa e hōʻeha ʻia nā cylinders i ka nui o ka hoʻoponopono mua, hoʻololi ʻia nā apo i hoʻokahi manawa.
Ma nā kaʻa he nui, me ka holo ʻana o 120 km, hoʻomaka ka leak o ka ʻaila crankshaft mua. Hoʻolei ʻia ka poloka ʻenekini mai ka hao a ʻaʻohe nickel coating, kahi e hoʻonui ai i ka waiwai a me ka hana ʻole o ka pilikia o kēia ʻenekini.
Ua hoʻokomo ʻia ka ʻenekini 2TR-FE ma nā hiʻohiʻona e like me:
- Land Cruiser Prado 120, 150;
- Tacoma;
- Fortuner;

Ke kuhiʻikeʻana
ʻO nā SUV Tuning, ʻo ia hoʻi ka hoʻokomo ʻana i nā huila nui ma luna o lākou, a me nā mea hana e hoʻonui ai i ke kaumaha o ke kaʻa, he mea paʻakikī i ka mīkini 2TR-FE ke huki i kēia nuipa. Hoʻokomo kekahi o nā mea nona nā superchargers mechanical (compressors) ma ka ʻāpana, e hoʻonui ai i ka mana a me ka torque. Ma muli o ka lākiō kaomi haʻahaʻa haʻahaʻa mua, ʻaʻole pono ka hoʻokomo ʻana o ka compressor i ke komo ʻana i ka poloka a me ke poʻo cylinder 2TR-FE.
ʻAʻole pālahalaha ka lalo o ka piston 2TR-FE, loaʻa iā ia nā puʻupuʻu valve, e hōʻemi ana i ka pilikia o ka hui ʻana o ka valve me ka piston, ʻoiai inā haki ke kaulahao, akā me ka hana kūpono, e lawelawe ana ke kaulahao manawa ma ke kaʻa a hiki i ka mīkini. ua hooponopono hou ia.
