Kodi zilembo B ndi K pa koyilo yoyatsira zimatanthauza chiyani?

Pakakhala zosokonekera pakugwira ntchito kwa injini yoyatsira mkati monga kuzimiririka kwa spark kapena spark yofooka, kusasunthika kosasunthika, kulephera kusintha liwiro lopanda ntchito, kuyambitsa zovuta kapena kulephera kuyambitsa injini yoyaka mkati, dips ndi jerks pamene kuyambira ndikuyenda, ndi zina zotero, ndiye zimakhala zomveka kuti muzindikire momwe ma coil akuyatsira. Kuti muchite izi, mungafunikire kudziwa zilembo za B ndi K pa koyilo.

Kodi zilembo B ndi K pa koyilo yoyatsira zimatanthauza chiyani?

Pa terminal ndi + chizindikiro kapena chilembo B (batire) imayendetsedwa ndi batire, ndi kalata K chosinthira chikugwirizana. Mitundu ya mawaya m'magalimoto imatha kusiyanasiyana, kotero ndizosavuta kutsata yomwe imapita.

*Makoyilo oyatsira amatha kusiyanasiyana malinga ndi kulimba kwa mafunde.

Momwe mungalumikizire koyilo yoyatsira molondola?

Kaya mbali ya galimoto, kugwirizana ndi chimodzimodzi:

• waya wotuluka pa loko ndi wofiirira ndipo amalumikizidwa ku terminal ndi chizindikiro "+" (chilembo B);
• waya wakuda womwe umachokera ku misa umagwirizanitsidwa ndi "K";
• chachitatu (mu chivindikiro) ndi cha waya wothamanga kwambiri.

Kukonzekera cheke

Kuti muwone coil yoyatsira, mudzafunika mphete ya 8 mm kapena wrench yotseguka, komanso tester (multimeter kapena chipangizo chofananira) chokhala ndi ohmmeter mode.

Mutha kuzindikira koyilo yoyatsira popanda kuichotsa mgalimoto:

• chotsani terminal yoyipa ku batri;
• kulumikiza waya wothamanga kwambiri kuchokera pa koyilo yoyatsira;
• kulumikiza mawaya opita ku materminal awiri a koyilo.

Kuti muchite izi, gwiritsani ntchito wrench ya 8 mm kuti mutulutse mtedza womangira mawaya ku ma terminals. Timadula mawaya, kukumbukira malo awo, kuti tisawasokoneze powakhazikitsanso.

coil diagnostics

Timayang'ana momwe mawotchi oyambira amagwirira ntchito poyatsira moto.

Kuti tichite izi, timagwirizanitsa kafukufuku wina woyesera ku "B" terminal, kafukufuku wachiwiri ku "K" terminal - kutuluka kwa mafunde oyambirira. Timayatsa chipangizocho mu ohmmeter mode. Kukaniza kwa kuwongolera koyambira koyambira koyatsira kuyenera kukhala pafupi ndi ziro (0,4 - 0,5 ohms). Ngati ili m'munsi, ndiye kuti pali dera lalifupi, ngati liri lapamwamba, pali dera lotseguka pozungulira.

Timawona mayendedwe achiwiri (high-voltage) akumapeto kwa koyilo yoyatsira.

Kuti tichite izi, timagwirizanitsa kafukufuku wina woyesera ku "B" terminal ya coil yoyatsira, ndipo kafukufuku wachiwiri ku zotsatira za waya wothamanga kwambiri. Timayesa kukana. Pamapiritsi achiwiri ogwira ntchito, ayenera kukhala 4,5 - 5,5 kOhm.

Kuyang'ana kukana kwa insulation pa nthaka. Pa cheke chotere, ndikofunikira kuti multimeter ikhale ndi megohmmeter mode (kapena megohmmeter yofunikira) ndipo imatha kuyeza kukana kwakukulu. Kuti tichite izi, timalumikiza kafukufuku wina woyesa ku "B" terminal ya coil yoyatsira, ndikusindikiza kafukufuku wachiwiri ku thupi lake. Kukana kwa kutchinjiriza kuyenera kukhala kwakukulu - 50 mΩ kapena kupitilira apo.

Ngati chimodzi mwa macheke atatuwa chikuwonetsa kusagwira ntchito, ndiye kuti koyilo yoyatsira iyenera kusinthidwa.
