Toyota 1HZ engine: nā mea a pau e pono ai ʻoe e ʻike
Hāʻawi ka 1HZ i ka hilinaʻi a me ka hilinaʻi i kēlā me kēia lā, a me ka pono kūpono a me ka hoʻokele wahie.
Ua hoʻohana ʻia nā ʻenekini diesel Turbocharged mai ka hopena o ke kenekulia i hala, akā ʻaʻohe kaʻa alanui i kēia mau lā i lako ʻole me ka turbocharger no ka hoʻonui ʻana i ka mana a me ka pono.
ʻAʻole naʻe ʻo ia ka hihia maʻamau, a ʻo ka mīkini diesel aspirated Toyota 1HZ i ka pae Landcruiser pono e noʻonoʻo ʻia ʻo ke aliʻi o nā diesel aspirated kūlohelohe.
He lālā o ka hui engine Toyota HZ, 1 i ka 1HZ e hōʻike ana he lālā ia o ka ʻohana hanauna mua.
ʻAʻole wale ka Toyota 1HZ diesel hiki ke hana i ka hana o kahi turbodiesel liʻiliʻi, e hoʻomau ʻia e hana pēlā no ka hapalua miliona mau mile, me ka hōʻike ʻana o kekahi mau mea hana i hoʻokahi miliona mau mile ma mua o ka pono o ka hana nui.
Hoʻohui i kēlā hilinaʻi maikaʻi loa i kēlā me kēia lā, kūpono kūpono a me ka hoʻokele wahie, a hiki iā ʻoe ke ʻike i ke kumu i lilo ai ka 1HZ, ʻoiai ʻaʻole he sprinter, i mea punahele me nā huakaʻi hele mamao a mamao.
ʻO kēlā me kēia loiloi o kahi ʻenekini 1HZ e kuhikuhi mau ana he ʻenekini ola lōʻihi kēia ʻaʻole e hāʻule i ka wikiwiki. Malia paha ʻo ka ʻaoʻao nui loa ʻo ka 1HZ wahie hoʻokele waiwai, mai 11 a 13 lita no 100km.
Aia kēia ma kahi kaʻa maʻamau i ka wikiwiki o ke alaloa a ʻoi aku ke kiʻekiʻe i ka wā e huki ai. Aia ia ma hope o nā kaʻa kaʻa ʻelua o kēia wā, akā ʻaʻole maikaʻi ia ma nā kūlana XNUMXWD piha piha.
ʻO nā hiʻohiʻona o kahi mīkini ʻōhule 1HZ ʻaʻole pono e hōʻike i kāna mau mea huna. Akā, ʻo ia ka hui pū ʻana o nā mea waiwai, ka hana akamai, a me kahi hoʻolālā kumu paʻa i hana ai ka 1HZ i mea mahalo nui ʻia.
Hoʻomaka ia me ka poloka hao a me ke poʻo cylinder (maʻamau i nā ʻenekini diesel a hiki i kēia lā). ʻO ka 4.2 lita (4164 cc ka pololei) 1HZ engine he 94mm a me 100mm.
Holo ka crank i ʻehiku mau bea nui. ʻO ka ʻenekini he ʻenekini ʻeono pahu me ka pahu pahu hoʻokahi ma luna o ke poʻo (hoʻokele ʻia e kahi kāʻei toothed rubber) a me ʻelua kiwikā no kēlā me kēia cylinder.
Hoʻokumu ka 4.2-lita inline eono-cylinder engine i ka 96 kW/285 Nm o ka mana. (Ke kiʻi ʻai: Wikimedia Commons)
Hoʻohana ka 1HZ i ka ʻenehana indirect injection a loaʻa iā ia ka lākiō kaomi o 22.4:1. ʻO ka mana i koi ʻia he 96 kW ma 3800 rpm a me 285 Nm ma 2200 rpm.
E hōʻike pū ana ke kiʻikuhi 1HZ injector pump i ka hoʻohana ʻana o ka ʻenekini i kahi ʻōnaehana hoʻokele kula kahiko a ʻaʻole i ka ʻenehana diesel hou.
ʻO ke kūkulu ʻana i ka hao hao o ke kaʻa he ikaika ia, akā ʻo ke kaumaha o ka mīkini 1HZ ma kahi o 300kg. ʻO ka nui o ka ʻaila ʻenekini 1HZ he 9.6 lita ke hoʻopiha maloʻo.
Ma Australia, he koho kaulana ka 1HZ i ka moʻo 80, i hoʻokuʻu ʻia i ka makahiki 1990 a ua manaʻo ʻia ʻo ia ka LandCruiser Toyota maikaʻi loa i hana ʻia (ʻaʻole naʻe i hōʻoia ʻia ka moʻo 300 hou loa no ia poʻo).
Ma ka 80 series form, ua kūʻai ʻia ka 1HZ me ka petrol six-cylinder a me 1HDT turbodiesel versions o ke kaʻa hoʻokahi, a ua hoʻomau ʻia kēia me ka moʻo 100 hou i ʻike i ka 1HZ i hoʻokomo ʻia i ke kumu hoʻohālike kumu ʻano ʻano like ʻole (ma ke ʻano he 105 series).
Me ka hiʻohiʻona maʻamau a me ka nui o nā mana o ke alanui, ʻaʻole ia he mea kupanaha ke kaulana loa ka 80. (Kiʻi kiʻi: Tom White)
Ua hoʻomau kēia i kēia kaʻa a hiki i ka makahiki 2007, i ka wā i ʻike ʻia ai ka 200 series.
Ma ka laina hana, ua ʻike ʻia ka Toyota 1HZ i ka 75 Series and Troop Carrier ma 1990 a kūʻai ʻia a hiki i 2007 i ka manawa i hoʻololi ʻia ai e nā ʻano turbodiesel. Ua hoʻohana pū ʻia ka diesel 1HZ i kekahi mau kaʻa kaʻa Toyota Coaster.
ʻO ka mea nui, no ka loaʻa ʻana o 1HZ i kāu Toyota hou, pono ʻoe e kūʻai i LandCruiser piha piha, ʻoiai ʻaʻole loaʻa iā Prado kēlā mīkini.
ʻAʻole ʻoe e ʻike i ka LandCruiser 1HZ me ka hoʻouna ʻakomi; inā he ʻenekini 1HZ, aia iā ʻoe ka hoʻololi lima.
He liʻiliʻi nā pilikia me ka mīkini 1HZ. Ma waho aʻe o kekahi mau hihia o nā poʻo cylinder māhā i ka wahi precombustion, maikaʻi ka nūhou.
ʻAʻole pilikia nā pahu pahu pahu pahu 1HZ inā ʻaʻole i wela ka ʻenekini, a ʻaʻole pilikia ka kāʻei manawa 1HZ inā hoʻololi ʻia kēlā me kēia 100,000 km.
Ua loaʻa i ka moʻo 75 kahi ʻōnaehana hapa manawa me kahi hihia hoʻololi e hāʻawi ana i ʻelua mau ʻāpana like ʻole o nā ratio gear.
ʻO ka manaʻo maʻamau e ʻōlelo ʻia e pono ka nānā ʻana i ka pauma wahie 1HZ ma hope o 400,000 km, a nui nā mea nona ka hoʻoholo e kūkulu hou i ke poʻo cylinder i ka manawa like.
He maʻalahi ka mālama ʻana, ʻoiai ʻo ka wahi o ka thermostat 1HZ ma ka ʻaoʻao lalo o ka poloka e paʻakikī ke komo me ka wehe ʻole ʻana i ka alternator.
ʻOiaʻiʻo, ʻaʻohe mea e mau loa, a i ka wā e pau ai ka 1HZ, nui nā mea nona ka hoʻoholo e kūʻai i kahi 1HZ i hoʻohana ʻia me nā mile liʻiliʻi a kūʻai aku.
He mea kaulana nā papa inoa ʻenekini 1HZ i kēia hihia, akā koho kekahi mau mea nona e kūkulu hou i kahi ʻenekini i loaʻa iā lākou.
Hiki ke kūʻai ʻia kahi pahu hana hou 1HZ me nā apo, nā bearings a me nā gaskets ma kahi o $1500, akā inā makemake ʻoe e kūkulu i kahi ʻenekini turbocharged e mākaukau e hoʻolilo ma kahi o pālua no kahi kit e hoʻokomo ʻia nā pistons kaomi haʻahaʻa.
ʻO ka moʻo 105 ma nā ʻano he nui ka hoʻomau o ka moʻo 80.
Pono ka hana nui inā ʻaʻole ʻoe e hana iā ʻoe iho akā e noʻonoʻo i nā ana a me ka mīkini ʻana o nā paia crankshaft a me nā cylinder.
Hiki ke loaʻa kahi ʻenekini hoʻohana maikaʻi no kekahi mau kaukani kālā, ʻoiai ʻo nā ʻāpana i kūkulu hou ʻia (me ka hiki turbo) hiki ke loaʻa no $5000 a i $10,000 a piʻi inā makemake ʻoe i kahi mea paʻakikī.
Loaʻa nui nā ʻāpana hana hou mai nā ʻoihana loea i kēia ʻano hana, akā pono ʻoe e hoʻolako i kahi kaʻa nui pani.
ʻO ka hoʻohālikelike maʻamau paha a ka poʻe i hana ai, ʻo ia ka kūkākūkā kahiko o 1HZ vs 1HDT, ʻoiai ke kūʻai ʻia aku nei ʻo 1HDT ma ka ʻaoʻao o 1HZ i nā kaʻa 80 a me 100 series, akā i kēia mau lā, ʻoi aku ka nui o ke kālā ma ke ʻano he mōhai hoʻohana.
No ke aha mai? No ka mea, ʻo ka 1HDT he ʻenekini diesel turbocharged a ʻo ka hopena he ʻoi aku ka mana a me ka torque (151kW/430Nm ma kahi o 96kW/285Nm).
E nīnau i kekahi mea pāʻani Toyota LandCruiser a ʻike lākou i ke ʻano o ka ʻenekini 1HD FTE. Loaʻa paha iā lākou kahi peʻa code engine!
Hāʻawi kēia i ka engine turbocharged i ka pono hana nui ma ke alanui, akā ma waho o ke alanui, kahi e noho aliʻi ai nā mea hoʻohana avid, ʻo ka maʻalahi a me ka hilinaʻi o ka 1HZ (a me ka pau ʻole o ka uila) e noho mau i ka mīkini koho no kekahi.
Mai ka ʻike loea, aia nā ʻokoʻa ʻē aʻe, me ka ʻoiaʻiʻo o ka hana ʻana o nā injectors 1HZ i loko o kahi keʻena pre-combustion (e hoʻolilo i ka 1HZ i ʻenekini indirect injection), ʻoiai ʻo ka 1HDT he hoʻolālā hoʻolālā pololei kahi e hoʻomaka ai ka puhi ʻana i loko.
No kēia kumu (ma waena o nā mea ʻē aʻe) ʻaʻole hiki ke hoʻololi ʻia nā poʻo cylinder o nā ʻenekini ʻelua, a ʻo ka like ʻole o ka hoʻopili ʻana o ka mīkini turbocharged ʻo ia hoʻi ʻaʻole kūpono nā ʻāpana haʻahaʻa.
ʻOiai ʻaʻole hāʻawi ʻo Toyota i kahi ʻenekini turbo 1HZ, ua hāʻawi ʻia kahi pahu turbo 1HZ i ka aftermarket no kēlā. Maikaʻi ka ʻōlelo ʻana ua ʻoi aku ka maikaʻi o ka hoʻolālā ʻana o kekahi o lākou ma mua o nā mea ʻē aʻe, akā i kēlā me kēia ʻano, hoʻokomo pinepine nā mea nona nā ʻenekini turbo 1HZ i kahi pyrometer (e nānā i ka wela o ke kinoea hoʻopau a hōʻike i ka paʻakikī o ka hana ʻana o ka mīkini) a nānā pono i ka heluhelu ʻana o kēia. mea ʻike. nilala.
ʻO nā hopena ma hope o ka mākeke turbocharger kaulana i nā makahiki he Safari Turbo 1HZ, AXT Turbo 1HZ a me Denco Turbo 1HZ kits.
Ua kūʻai ʻia ka 1HDT ma ka ʻaoʻao o ka 1HZ i nā kaʻa series 80 a me 100. (Kiʻi kiʻi: Tom White)
Ua like nā kumu o kēlā me kēia pahu; he 1HZ turbo manifold, ka pahu turbocharger pono'ī a me ka paipu pono e hoʻohui ia mea a pau.
Ma kahi o nā pahu turbo maʻamau, ʻoi aku ka nui o nā tuners i kahi mea hoʻonui hoʻonui a, no ka hana kiʻekiʻe, kahi intercooler.
Eia naʻe, i kēlā me kēia hihia, ua like ka pahuhopu; e hoʻomaikaʻi i ka hoʻokele kaʻa a me ka wikiwiki, ʻoi aku hoʻi i ka huki ʻana. ʻO kahi pahu turbo kumu ma waena o $3000 a me $5000 me ka hoʻokomo ʻana.
I kēia manawa, ke hoʻāʻo nei ka poʻe i mahalo i ka maʻalahi o ka 1HZ e hoʻokele i ka turbocharging a hoʻohana i nā ʻano kuʻuna e hoʻonui ai i ka hiki o ka mīkini.
No kēia mau mea nona, ʻo ka ʻenekini turbo maikaʻi loa no ka 1HZ ʻaʻole ia he turbo. Inā ʻaʻole pono ʻoe i ka wikiwiki hou aʻe, he manaʻo kūpono hoʻi kēia.
I nā manawa he nui, ua hoʻohana nā mea nona ka huli ʻana maʻamau a me ka hoʻokomo ʻana i ka pauku maikaʻi, me nā mea unuhi 1HZ a me kahi ʻōnaehana hoʻopau pololei (maʻamau 3.0-inihi), e kiʻi i nā mea e pono ai.
