Kiʻikuhi uwila no 3-wire crankshaft position sensor
Nā mea
Ma kēia ʻatikala, e aʻo ʻoe e pili ana i ka XNUMX-wire crankshaft position sensor a me kāna kiʻi wili.
Inā ua hoʻokomo a hoʻāʻo paha ʻoe i kahi sensor crankshaft 3-wire iā ʻoe iho, ʻike paha ʻoe i ka hana ʻana. ʻAʻole maʻalahi ka ʻike ʻana i nā uea 3. Ma kekahi ʻaoʻao, pono ʻoe e ʻike i kahi e hoʻopili ai iā lākou.
ʻO ka crankshaft sensor kahi mea uila koʻikoʻi no ka hoʻoholo ʻana i ka wikiwiki o ka mīkini a me ka manawa hoʻāla. Hele mai ka mea ʻike crankshaft 3-wire me 5V a i ʻole 12V kuhikuhi, hōʻailona, a me nā pine lepo. Hoʻopili kēia mau pine ʻekolu i ka ECU o ke kaʻa.
"E hoʻomaopopo: Ma muli o ke ʻano o ke kaʻa, ʻokoʻa paha ke kiʻikuhi pili o ka crankshaft sensor."
E aʻo i nā mea a pau e pili ana i 3-wire crankshaft sensor mai ka ʻatikala ma lalo nei.
Pono ʻoe e ʻike i kekahi mea e pili ana i ka crankshaft sensor
ʻO nā hana nui o ka crankshaft sensor ʻo ia ka hoʻoholo ʻana i ka wikiwiki o ka mīkini a me ka manawa ignition. He ʻāpana koʻikoʻi kēia sensor o nā ʻenekini diesel a me ka ʻaila.
Nānā. Ma muli o ke ʻano o ke kaʻa, ʻokoʻa paha ke kiʻi pili o ka crankshaft sensor.
No ka laʻana, hele mai kekahi mau hiʻohiʻona me ka ʻike 2-wire a hele mai kekahi me ka sensor 3-wire. I kēlā me kēia hihia, ʻaʻole e ʻokoʻa ka mīkini hana a me ka hoʻolālā pili.
ʻ Tiplelo Aʻoaʻo wikiwiki: Hiki ke hoʻokaʻawale ʻia ka sensor crankshaft 3-wire e like me nā mea ʻike hopena Hall. Loaʻa iā ia kahi magnet, transistor, a me kahi mea kila e like me germanium.
Kiʻikuhi uwila no 3-wire crankshaft sensor
E like me kāu e ʻike ai mai ke kiʻikuhi ma luna nei, hele mai ka sensor crankshaft 3-wire me ʻekolu uea.
- Waea kuhikuhi
- uwea hoailona
- ka honua
Hoʻopili ʻia nā uea ʻekolu i ka ECU. Hoʻohana ʻia kekahi uea e ka ECU. Ua ʻike ʻia kēia uea ma ke ʻano he 5V (a i ʻole 12V) uea kuhikuhi.
Hele ka uea hōʻailona mai ka sensor a i ka ECU. A ʻo ka hope, hele mai ka uea honua mai ka ECU, e like me ka uea kuhikuhi 5V.
Volta kuhikuhi a me ka uila hōʻailona
No ka hoʻomaopopo pono ʻana i kahi kaapuni uila, pono ʻoe e ʻike i ka kuhikuhi a me nā voltages hōʻailona.
ʻO ka voltage kuhikuhi ka volta e hele mai ana mai ka ECU i ka mea ʻike. I ka hapanui o na hihia, he 5 V keia volt, a i kekahi manawa hiki ke 12 V.
ʻO ka voltage hōʻailona ka voltage i hāʻawiʻia i ka ECU mai ka meaʻike.
ʻ Tiplelo Aʻoaʻo wikiwiki: ʻO ka nānā ʻana i ka manual o ka mea nona kāu kaʻa ʻo ia ke ala maikaʻi loa e hoʻoholo ai i ke ʻano o ka crankshaft sensor. No ka laʻana, loaʻa i ka manual nā kikoʻī e like me ke ʻano sensor a me ka volta.
Pehea ka hana ʻana o kahi sensor 3-wire?
Ke hoʻokokoke kahi mea i ka mea ʻike, hoʻololi ke kahe magnetic o ka mea ʻike, a loaʻa i kahi volta. ʻO ka hope, hoʻonui ka transistor i kēia volta a hoʻouna iā ia i ke kamepiula ma luna o ka papa.
ʻO ka ʻokoʻa ma waena o 2-wire a me 3-wire sensor
ʻO ka sensor 3-wire he ʻekolu pili i ka ECU. Loaʻa i kahi mea ʻike ʻelua uea ʻelua mau pilina. Loaʻa iā ia nā uea hōʻailona a me ka lepo, akā ʻaʻohe uea kuhikuhi no ka ʻike kūlana crankshaft XNUMX-wire. Hoʻouna ka uea hōʻailona i ka uila i ka ECU, a hoʻopiha ka uea honua i ke kaapuni.
ʻEkolu ʻano o nā mea ʻike crank
ʻEkolu ʻano o nā mea ʻike crankshaft. Ma kēia ʻāpana, e wehewehe pōkole wau iā lākou.
inductive
Hoʻohana ʻia ka mea hoʻoheheʻe inductive i kahi magnet e kiʻi i nā hōʻailona walaʻau. Hoʻokomo ʻia kēia mau ʻano mea ʻike ma luna o ka poloka cylinder a hiki iā ʻoe ke hoʻonoho i ka crankshaft sensor ma hope o ka crankshaft a i ʻole flywheel.
ʻAʻole pono nā ʻano ʻano inductive i kahi kuhikuhi voltage; hana lākou i kā lākou iho uila. No laila, ʻo ka sensor ʻelua uea he inductive-type crankshaft sensor.
Mīkiniʻimi hopena Hall
Aia nā mea ʻike Hall ma kahi like me nā mea ʻike inductive. Eia nō naʻe, pono kēia mau sensor i ka mana o waho e hana. No laila, ua hoʻolako ʻia lākou me kahi uea kuhikuhi voltage. E like me kaʻu i ʻōlelo ai, hiki i kēia volta kuhikuhi ke 5V a i ʻole 12V. Hoʻokumu kēia mau mea ʻike i kahi hōʻailona kikohoʻe mai ka hōʻailona AC i loaʻa.
ʻ Tiplelo Aʻoaʻo wikiwiki: ʻEkolu-uea crankshaft sensor o ke ano Hall.
Nā mea ʻike hoʻopuka AC
ʻOkoʻa iki nā mea ʻike hoʻopuka AC mai nā mea ʻē aʻe. Ma kahi o ka hoʻouna ʻana i nā hōʻailona kikohoʻe e like me ka hana ʻana o nā mea ʻike Hall, hoʻouna nā mea ʻike me kahi hoʻopuka AC i kahi hōʻailona uila AC. Hoʻohana pinepine ʻia kēia mau ʻano sensor i nā ʻenekini Vauxhall EVOTEC.

ʻEhia mau uwea i hoʻopili ʻia me ka ʻike kūlana crankshaft?
Hiki ke ʻokoʻa ka helu o nā uea ma muli o ke ʻano o ke kaʻa. No ka laʻana, hele mai kekahi mau hiʻohiʻona kaʻa me 2-wire sensor a hele mai kekahi me 3-wire sensor.
E like me kāu e hoʻomaopopo ai, ʻelua mau uea ka mea ʻike uea ʻelua, a ʻo ka mea ʻike uea ʻekolu he ʻekolu uea.
No ke aha e pono ai i nā mea ʻike crankshaft 3-wire i kahi kuhikuhi voltage?
Pono nā mea ʻike crankshaft ʻekolu uea i ka volta mai kahi kumu waho e hoʻohua ai i ka volta hōʻailona. No laila, hele mai kēia mau mea ʻike me ʻekolu mau hopena a ʻo kekahi o lākou e hōʻike ana i ka volta kuhikuhi. ʻO nā pahu ʻelua ʻē aʻe no ka hoʻopili ʻana i ka hōʻailona a me ka honua.
Eia nō naʻe, ʻaʻole pono nā mea ʻike crankshaft 2-wire i kahi kuhikuhi voltage. Hāʻawi lākou i kā lākou volta ponoʻī a hoʻohana iā ia e hana i ka volta hōʻailona.
ʻO 5V ka volta kuhikuhi no kēlā me kēia mea ʻike crankshaft?
ʻAʻole, ʻaʻole e 5V ka volta kuhikuhi i kēlā me kēia manawa. Hele mai kekahi mau mea ʻike crankshaft me kahi kuhikuhi 12V. Akā e hoʻomanaʻo, ʻo kahi kuhikuhi 5V ka mea maʻamau.
No ke aha ka mea maʻamau ka 5V i ka ʻoihana kaʻa?
ʻOiai ke hāʻawi ʻia nei nā pihi kaʻa ma waena o 12.3V a me 12.6V, hoʻohana wale nā mea ʻike i ka 5V e like me kā lākou volta kuhikuhi.
No ke aha ʻaʻole hiki i nā mea ʻike ke hoʻohana i nā 12V āpau?
ʻAe, paʻakikī iki. No ka laʻana, ke hoʻomaka ʻoe i ke kaʻa, hoʻomaka ka alternator i loko a hoʻopuka i kahi uila hou aʻe ma waena o 12.3 a 12.6 volts.
Akā ʻaʻole hiki ke ʻike ʻia ka volta e puka mai ana mai ka generator. Hiki iā ia ke hoʻopuka i ka 12V a i kekahi manawa hiki iā ia ke hoʻopau i ka 11.5V. No laila, ʻoi aku ka pilikia o ka hana ʻana i nā mea ʻike crankshaft 12V. Akā, hana nā mea hana i nā mea ʻike 5V a hoʻopaʻa i ka volta me kahi mea hoʻoponopono uila.
Hiki iā ʻoe ke nānā i ke kūlana crankshaft?
ʻAe, hiki iā ʻoe ke nānā. Hiki iā ʻoe ke hoʻohana i ka multimeter digital no kēia. E nānā i ke kū'ē o ka meaʻike a hoʻohālikelike me ka waiwai kū'ē nominal. Inā loaʻa iā ʻoe kahi ʻokoʻa nui ma waena o kēia mau waiwai ʻelua, ʻaʻole hana pono ka crankshaft sensor.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
