He kūpono no Volvo D4 ʻaila kaomi ʻaila 22899626

ʻO ka sensor kaʻa ka mea hoʻokomo o ka ʻōnaehana kamepiula kaʻa, e hoʻohuli ana i nā ʻike kūlana hana like ʻole (e like me ka wikiwiki o ke kaʻa, ka mahana o nā ʻano media like ʻole, nā kūlana hana ʻenekini, a me nā mea ʻē aʻe) i nā hōʻailona uila a hoʻouna iā lākou i ke kamepiula, i hiki ai i ka ʻenekini ke hiki. e noho ma kahi kūlana hana maikaʻi loa.

I ka ʻimi ʻana i nā hewa o nā mea ʻike kaʻa, ʻaʻole pono mākou e nānā wale i nā mea ʻike, akā e nānā pū i ke kaula uila, nā mea hoʻohui a me nā kaʻa pili i waena o nā mea ʻike a me ka mana uila.

ʻO kekahi o nā hiʻohiʻona o ka hoʻomohala ʻenehana kaʻa ʻo ia ka hoʻohana ʻana i ka mana uila. Wahi a ka hana o nā mea ʻike, hiki ke hoʻokaʻawale ʻia lākou i nā sensor e ana ana i ka mahana, ke kaomi, ke kahe, ke kūlana, ka ʻike kinoea, ka wikiwiki, ka mālamalama, ka haʻahaʻa maloʻo, ka mamao a me nā hana ʻē aʻe, a hana lākou a pau i kā lākou mau hana. Ke hāʻule ka mea ʻike, ʻaʻole e hana maʻamau ka mea pili a i ʻole. No laila, he mea koʻikoʻi ke kuleana o nā sensor i nā kaʻa.

I ka wā ma mua, hoʻohana wale ʻia nā mea ʻike kaʻa i nā ʻenekini, akā ua hoʻonui ʻia i nā chassis, kino a me nā kukui a me nā ʻōnaehana uila. Hoʻohana kēia mau ʻōnaehana ma mua o 100 mau ʻano ʻike. I loko o nā ʻano sensor like ʻole, ʻo nā mea maʻamau:

ʻO ka mea ʻike puʻe intake: hōʻike ia i ka hoʻololi ʻana o ke kaomi piha i loko o ka intake manifold a hāʻawi i kahi hōʻailona kuhikuhi no ka ECU (engine electronic control unit) e helu i ka lōʻihi o ka hoʻokele wahie;

Ea kahe ana: ana i ka nui o ka ea inhaled e ka engine a haawi ia ia i ka ECU ma ke ano he hoailona kuhikuhi no ka wahie injection manawa;

ʻO ka mea ʻike kūlana throttle: ana i ke kihi wehe o ka throttle a hāʻawi iā ia i ka ECU ma ke ʻano he hōʻailona kuhikuhi no ka ʻoki ʻana i ka wahie, wahie/ea ratio.

Crankshaft position sensor: ʻike i ka holo ʻana o ka crankshaft a me ka mīkini a hāʻawi iā ia i ka ECU ma ke ʻano he hōʻailona kuhikuhi e hoʻoholo ai i ka manawa hoʻāla a me ke kaʻina hana;

Oxygen sensor: ʻike i ka ʻike o ka oxygen i loko o ke kinoea hoʻopau a hāʻawi iā ia i ka ECU ma ke ʻano he hōʻailona kuhikuhi no ka mālama ʻana i ka lākiō wahie / ea kokoke i ka waiwai maikaʻi (theoretical value);
