ʻO ka pinepine, ʻo ka haki ʻana i ka ʻōnaehana hoʻāla kaʻa e pili ana i ka hōʻino ʻana i ka maikaʻi o nā pilina uila i ke kaapuni, a i ʻole ka leakage o kēia manawa i nā uea kiʻekiʻe. E hoʻopaʻa inoa mākou i nā mea āu e pono ai e hoʻolohe mua inā e kū mai nā pilikia i ka hana ʻana o ka ʻōnaehana hoʻokele kaʻa, a me ka algorithm e hana ai.

1. E nānā i ke kūlana o ka hoʻopaʻa ʻana o ka pākaukau me kahi voltmeter. Pono ka volta ma luna o ia mea ma kahi o 9,5 V. A i ʻole, pono e hoʻopiʻi a hoʻololi ʻia ka pākaukau.
2. E nānā i ka maikaʻi o nā mea hoʻopili ma ka module coil ma nā pahu kukui a pau.
3. E nānā i nā ihoiho a pau. ʻAʻole pono lākou i nā waihona ʻeleʻele nui, a ʻo ka mamao ma waena o nā electrodes e pili ana i 0,7 ... 1,0 mm.

ʻO ka pinepine, aia nā pilikia i ka uhaki ʻana i ka maikaʻi o nā pilina a i ʻole ka leakage o kēia manawa i nā uea kiʻekiʻe-voltage. E nānā i kā lākou hoʻokaʻawale ʻana, ke ʻano o ka coil ignition, ka laka ʻana, ka fuse coil.

E hoʻomanaʻo, ʻo ke kumu e hoʻomaka ʻole ai ka ʻenekini hoʻopau i loko, ʻo ia ka ʻōnaehana anti-theft o ke kaʻa. Ma mua o ka hoʻomaka ʻana, e nānā i kona kūlana.

Nā kumu maʻamau o nā hala

Ua pōʻino ka uwea hoʻāla uila

ʻO ka pinepine, ʻike ʻia nā haki i loko o ka ʻōnaehana ignition i nā pilina pili o nā kaapuni uila, e komo pū nā uwea uila kiʻekiʻe. ʻO ka manawa pinepine, ma muli o ka luku ʻia ʻana o kā lākou insulation, ua haki ka uila i loko o ke kino, kahi e hoʻopilikia ai i ka hana ʻana o ka mīkini hoʻopau i loko. He mea maikaʻi ke nānā i ke kuʻi ʻana o nā uea kiʻekiʻe-voltage i ka pōʻeleʻele. A laila ʻike maopopo ʻia ka ʻulaʻula e puka mai ana.

E nānā mau ka maʻemaʻe o ka hoʻokuʻu nā uwea uila kiʻekiʻe. ʻO ka ʻoiaʻiʻo. ʻO ka ʻaila e kau ana ma luna o ko lākou ʻili e hoʻopalupalu loa i ka insulation, a huki i nā ʻāpana o ka lepo a me ka lepo i laila, e hiki ai ke hoʻopau i ka uila.

Ma nā insulators o nā kukui, hiki ke ʻike ʻia nā "ala" kahi e hele ai ka haki. Inā ʻaʻole kūpono ka mana i nā uea uila kiʻekiʻe, a laila pono ʻoe e nānā i nā ʻāpana haʻahaʻa haʻahaʻa o ka ʻōnaehana ignition, ʻo ia hoʻi, ka hāʻawi ʻana o ka volta mai ka pā a i ka coil ignition. ʻO nā hana ʻino paha ʻo ia ka hoʻololi ʻā a i ʻole ka fuse puhi.

ʻO ka manawa pinepine nā kumu o ka hana hewa ʻana i ka ʻōnaehana he pilikia me nā plugs spark. Ma kahi kukui maikaʻi:

• ʻAʻole i puhiʻia nā electrodes ma luna, aʻo ka āpau ma waena o lākou he 0,7 ... 1,0 mm;
• ʻaʻohe ʻeleʻele ʻeleʻele, nā ʻāpana o ka insulator ma ka hihia;

Hiki iā ʻoe ke heluhelu i ka ʻike e pili ana i ka hoʻoholo ʻana i kona ʻano ma ke ʻano o ke kukui a ʻike i kahi ʻenekini hoʻopau i loko o kahi ʻatikala ʻokoʻa.

Kuhi hewa ʻole ke kīʻā ahi

Hiki ke hana hewa ʻia kēlā me kēia kanaka no nā kumu ʻelua:

• nā pilina pili paʻa ʻole a i ʻole kahi kīnā ʻole i ka ʻāpana haʻahaʻa haʻahaʻa o ka ʻōnaehana hoʻāla;

Ka uhi paheʻe a me ka mea hoʻolaha

ʻO nā kumu o ka misfire he haki paha i ka hana o ka crankshaft a me ka camshaft position sensors (hiki iā ʻoe ke ʻike pehea e nānā ai i ka sensor Hall ma kahi ʻatikala ʻokoʻa).

Ma nā kaʻa carbureted, ʻo ka pilikia uhi mea hoʻolaha. ʻIke pinepine ʻia nā māwae a i ʻole ka pōʻino. Pono e hana ʻia nā diagnostics ma nā ʻaoʻao ʻelua, ma hope o ka holoi ʻana mai ka lepo a me ka lepo. Pono e hoʻolohe i ka hiki ʻana mai o nā māwae, nā ala kalapona, nā mea puhi ahi a me nā hemahema ʻē aʻe. pono ʻoe e nānā i ke ʻano o nā pulupulu, a me ka paʻa o kā lākou kaomi ʻana i ka ʻili pili o ka slider. I ka pau ʻana o ka hoʻoponopono, ʻoi aku ka maikaʻi e pīpī i ka ʻili o ka ʻōnaehana me kahi desiccant.

ʻŌwili uila

ʻO kahi kumu maʻamau o nā pilikia i loko o ka ʻōnaehana ʻo ia ka ignition coil (ma hope o ka pōkole pōkole). ʻO kāna hana ʻo ka hoʻokumu ʻana i kahi hoʻokuʻu kiʻekiʻe-voltage ma ka plug spark. He ʻokoʻa ke ʻano o nā wili. Ua hoʻohana nā mīkini kahiko i nā wili me ka wili hoʻokahi, ʻo nā mīkini hou i hoʻohana i nā modula māhoe a i ʻole monolithic i loaʻa nā uea kiʻekiʻe a me nā lugs. I kēia manawa, hoʻokomo pinepine ʻia nā coils no kēlā me kēia cylinder. Kau ʻia lākou ma nā kukui, ʻaʻole hāʻawi kā lākou hoʻolālā no ka hoʻohana ʻana i nā uea kiʻekiʻe-voltage a me nā ʻōlelo aʻoaʻo.

Ma nā kaʻa kahiko, kahi i hoʻokomo ʻia ai kahi kaapuni pōkole i kahi kope hoʻokahi, ʻo kona hāʻule ʻole (ka wili ʻana a i ʻole ka pōkole pōkole i loko) ua alakaʻi ʻia i ka ʻoiaʻiʻo ʻaʻole i hoʻomaka ke kaʻa. Ma nā kaʻa hou, inā pilikia kekahi o nā coils, hoʻomaka ka ʻenekini hoʻopau i loko e "troit".

Hiki iā ʻoe ke ʻike i ka coil ignition ma nā ʻano like ʻole:

I ka wā o ka nānā ʻana, pono e nānā pono i nā ʻāpana insulating o kēia manawa. ʻAʻole pono e loaʻa iā lākou nā ʻāpana o ka soot, a me nā māwae. Inā i ka wā o ka nānā ʻana ua ʻike ʻoe i kēlā mau hemahema, ʻo ia ka mea e pono ke hoʻololi ʻia ka coil.

Nā diagnostics o ka module ignition

Pono e hoʻokō ʻia nā diagnostics i ʻōlelo ʻia i ka wā e kū mai ai nā hewa aʻe:

ʻO ka mea kūpono, pono e hoʻohana ʻia kahi scanner loea a me kahi mea hoʻāʻo kaʻa e ʻike i ka module ignition. Eia nō naʻe, no ka mea he kumukūʻai kēia mea hana a hoʻohana wale ʻia i nā keʻena lawelawe ʻoihana, hiki ke hiki i ka mea hoʻokele maʻamau ke nānā i ka module ignition wale nō me nā ala improvised. ʻO ia hoʻi, ʻekolu mau ʻano hōʻoia:

1. Hoʻololi i ka module me kahi mea hana i ʻike ʻia. Eia naʻe, nui nā pilikia ma ʻaneʻi. ʻO ka mua ka nele o kahi kaʻa hāʻawi. ʻO ka lua, ʻo ia ke ʻano like o ka module ʻē aʻe me ka mea i nānā ʻia. ʻO ke kolu - pono e ʻike ʻia nā uea kiʻekiʻe i ke kūlana maikaʻi. No laila, ʻaʻole hoʻohana ʻia kēia ʻano hana.
2. ʻano haʻalulu module. No ka ʻike ʻana i ka node, pono ʻoe e neʻe i ka poloka o nā uea, a me ka module ponoʻī. Inā i ka manawa like ke hoʻololi ʻana o ke ʻano hana o ka ʻenekini hoʻoheheʻe kūloko, ʻo ia hoʻi, aia kahi pilina maikaʻi ʻole e pono e hoʻoponopono ʻia.
3. Ana kū'ē. No ka hana ʻana i kēia, pono ʻoe i kahi ohmmeter (kahi multimeter e hana ana ma ke ʻano ana ʻana i ke ʻano kūʻē uila). ʻO nā ʻimi noiʻi o ka hāmeʻa e ana i ke kūʻē ʻana ma nā hopena ma waena o 1 a me 4, a me 2 a me 3 cylinders. Pono e like ka waiwai kū'ē. No kona nui, hiki ke ʻokoʻa no nā mīkini like ʻole. No ka laʻana, no ka VAZ-2114, pono kēia waiwai ma kahi o 5,4 kOhm.
