ʻO ka mea ʻike puʻe intake manifold.
ʻO ka hoʻolālā ʻana o ka ʻenekona puʻe intake manifold
No ka mea, aia kahi kaapuni amplifier i loko o ka mea ʻike kaomi manifold, pono ia i ʻekolu mau uea o ka laina mana, ka laina ʻāina a me ka laina hoʻopuka hōʻailona, e like me ʻekolu mau hopena ma nā ʻāpana wili, kēlā me kēia, ka mana mana (Vcc ), ke kahua honua (E) a me ka pahu puka hōʻailona (PIM), a ua hoʻopili ʻia nā pahu ʻekolu i ka ECU kamepiula hoʻomalu ma o ka mea hoʻohui uea a me ka uea.
I mea e hōʻemi ai i ka haʻalulu o nā ʻāpana uila o loko o ka intake manifold pressure sensor, ua hoʻokomo pinepine ʻia i kahi kūlana liʻiliʻi ka haʻalulu o ke kaʻa, a ma luna o ka ea intake e pale aku i ke kinoea mai ka intake manifold mai ka hoʻouka ʻana. ka mea ike kaomi. Eia kekahi, ʻae ka intake manifold pressure sensor i ke kaomi paipu intake mai lalo mai e pale i ka ʻāpana ʻike hōʻailona mai ka haumia ʻana, no laila ke kiʻi ʻia ke kinoea paipu intake i hōʻiliʻili ʻia mai ka intake manifold kokoke i ka throttle ma o ka paipu pulupulu e loaʻa mai ka hopena haʻahaʻa o ka. mīkini paʻi paʻi.

1. Nānā hiʻona
I ka nānā ʻana, e ʻimi wale i ka hose ʻōpala mai ka intake manifold kokoke i ka throttle end e ʻike ai i ka mea ʻike kaomi manifold ma ke kaʻa. ʻO ka mea mua, me ka pani ʻana i ka laka hoʻāla, e nānā i ka pili pono ʻana o ka mea hoʻohui uea intake manifold pressure sensor a ua pio ka hose. A laila e hoʻomaka i ka ʻenekini e ʻike inā ʻaʻole i hoʻopaʻa paʻa ʻia ka ʻili a me ka liki
2. ʻO ka hoʻāʻo ʻana i nā mea hana
(1) E ho'ā i ke kuapo ho'ā (ON), a e ho'āʻo i ka waiwai uila ma waena o ka pahu Vcc a me E2 me ka hoʻokuʻu uila DC o ka multimeter (DCV-20). ʻO ke kumukūʻai o ka volta ka waiwai o ka mana i hoʻohui ʻia e ka ECU i ka ʻenekona kaomi manifold. Pono ka waiwai maʻamau: Ma waena o 4.5 a me 5.5V, inā ʻaʻole pololei ka waiwai, pono ʻoe e nānā i ka uila uila a i ʻole ka pilina ma waena o nā uea, i kekahi manawa aia paha ka pilikia i ka ECU kamepiula mana.
(2) E ho'ā i ke kuapo ho'ā (ON kūlana), a huki i ka hose pahu pahu mai ka intake manifold pressure sensor, i pili ka intake o ka intake manifold pressure sensor i ka lewa, a laila e ho'āʻo i ka hōʻailona uila puka puka ( ka waiwai uila ma waena o PIM a me ka uea honua E2), ʻo ka waiwai maʻamau: Ma waena o 3.3 a me 3.9V, inā he kiʻekiʻe a haʻahaʻa paha ka uila puka, hōʻike ia he hewa ka intake manifold pressure sensor a pono e hoʻololi.
(3) E ho'ā i ke kuapo ho'ā (ON kūlana), e wehe i ka hose pulupulu ma luna o ka intake manifold pressure sensor, e ho'āʻo i kaʻokoʻa likeʻole (vacuum degree) ka waiwai o ka uila ma waena o ka hoʻouna ʻana i ka uwila hoʻoili uila hōʻailona PIM a me ka uea honua E2 i ka wā e kau ana i ke kaomi. Pono e hoʻonui i ka waiwai o ka volta me ka ulu ʻana o ke kaomi ʻino i hoʻohana ʻia, inā ʻaʻole, e hōʻike ana i ka hewa o ke kaʻapuni ʻike hōʻailona i ka sensor a pono e hoʻololi ʻia.
Aia ma hea ka ʻenekona intake manifold pressure?
ʻO ka intake manifold pressure sensor he mea ʻike i hoʻokomo ʻia ma ka paipu kinoea intake manifold, nona ʻekolu uea, hoʻokahi no 5 volts, hoʻokahi no 5 volts o ke ala hoʻi, ʻo ia hoʻi, ka laina ʻino, a ʻo kekahi he hōʻailona. laina no ka Ecu.
ʻO ka intake manifold pressure sensor he ʻano koʻikoʻi loa o ka ʻike ma Type D, ʻo ia hoʻi, nā ʻōnaehana hoʻoneʻe wahie velocity density, e pāʻani ana i ke kuleana o ka hoʻololi ʻana i ka hoʻololi kaomi i ka manifold intake i hōʻailona uila.
Hoʻoholo ka computer control (ECU) i ka nui o ka ea e komo ana i loko o ka cylinder ma muli o kēia hōʻailona a me ka wikiwiki o ka ʻenekini (hōʻailona i hāʻawi ʻia e ka ʻenekini wikiwiki i hoʻokomo ʻia i ka mea hoʻolaha).
ʻIke ka mea ʻike puʻe intake i ke kaomi piha o ka intake manifold ma hope o ka puʻupuʻu a me ka valve, a ʻike ʻo ia i ka hoʻololi ʻana o ke kaomi pono i loko o ka manifold e like me ka wikiwiki a me ka ukana.
A laila, hoʻololi ʻia i ka volta hōʻailona a hoʻouna ʻia i kahi mea hoʻokele uila (ECU), nāna e hoʻomalu i ka nui o ka wahie maʻamau e like me ka nui o kēia volta hōʻailona.
Inā makemake ʻoe e ʻike hou aku, e hoʻomau i ka heluhelu ʻana i nā ʻatikala ʻē aʻe ma kēia pūnaewele!
E ʻoluʻolu e kelepona iā mākou inā makemake ʻoe i ia mau huahana.
