Momwe mungadziwire sensor ya camshaft?

Magalimoto onse amakono ali ndi gawo lofunikira monga camshaft sensor. Ntchito yake yayikulu ndikupereka lamulo kuti mafuta alowe m'masilinda. Ngati sensa ili yolakwika, ndikofunikira kudziwa chomwe chalephereka ndikuyisintha.

Kuchita kwa DPRV (camshaft position sensor) kumadalira kulamulira kwa kutentha. Kutentha kwakukulu kudzawononga. Sensa sigwira ntchito ngati mawaya omwe amadutsira ndi kulandira chizindikiro alibe dongosolo.

Udindo wofunikira umasewera ndi zolakwika kapena kuipitsidwa kwa sensa yokha. Komanso, m'mikhalidwe yovuta, kuyendetsa galimoto (kuyendetsa galimoto, kuyendetsa katundu), sensa imatha kusuntha kapena kuipiraipira, dera lalifupi lidzachitika. Pofuna kuthetsa kuwonongeka kwa sensa pa nthawi yosayenera, chitani matenda ake.

Kuthetsa DPRV

Ngati chizindikiro cha Check Engine chili kale pagawo (sichikhoza kuwunikira nthawi zonse, koma chikuwoneka nthawi ndi nthawi), muyenera kungowerenga nambala yosweka pogwiritsa ntchito chipangizo chowunikira. Ngati mulibe chipangizo choterocho ndipo sizingatheke kugula, muyenera kulankhulana ndi akatswiri.

Mukalandira nambala yeniyeni yosweka ndikuyisintha, tikupangira kuti muyese mayeso osavuta. Kukhalapo kwa imodzi mwa zizindikiro zolephera za DPRV zomwe zatchulidwa pamwambapa sizimasonyeza nthawi zonse kuti sensa iyenera kusinthidwa. Zimachitika kuti gwero la vuto ndi cholakwika mu waya, cholumikizira, etc. N’zotheka kuthetsa mavuto amenewa nokha.

Koma kuti muwone momwe sensor imagwirira ntchito, muyenera kuchitapo kanthu. Zoonadi, chizindikirocho chimakhala chovuta kuchizindikira popanda zida zapadera. Koma chidziwitso chofunikira chidzaperekedwa ndi diagnostics ndi multimeter.

Momwe mungadziwire camshaft sensor wiring?

Choyamba, dziwani momwe cholumikizira cha sensor chimakhalira ndi mawaya omwe amapitako. Onetsetsani kuti mulibe dothi, mafuta, kapena dzimbiri mmenemo zomwe zingayambitse zosokoneza. Dziwani mawaya omwe ali ndi zolakwika. Zimachitika kuti mavuto amapangidwa ndi mawaya osweka, kukhudzana koyipa kapena zolakwika muzotchingira zosanjikiza zomwe zimayambitsidwa ndi kutentha kwambiri. Mawaya a DPRV sayenera kukhudzana ndi mawaya amphamvu kwambiri amagetsi oyatsira.

Kenako, timatenga, "amadziwa" kuti azindikire kufunika kwa kusinthana ndi kulunjika (AC ndi DC, motero). Koma muyenera kudziwiratu za zomwe zizindikirozi ziyenera kukhala za sensa yomwe imagwiritsidwa ntchito pagalimoto yanu. Mu masensa ena, zolumikizira zimapangidwira kuti muzitha kulumikiza mawaya owonjezera kuti muwerenge deta ndi multimeter.

Ngati izi sizingatheke, yesani kulumikiza cholumikizira cha RPF ndi kulumikiza mawaya owonda amkuwa ku cholumikizira chilichonse. Kenako, ikani cholumikizira m'malo mwake kuti mawaya awiri atuluke m'thupi lake.

Njira ina ndikuboola mawaya aliwonse ndi singano kapena pini (samalani kuti musafupikitse mawaya!). Pambuyo pazidziwitso zotere, malo owonongeka otsekemera ayenera kukulungidwa bwino ndi tepi yamagetsi kuti chinyezi chisalowe mkati.

diagnostics wa awiri waya camshaft udindo sensa:

• Ngati galimoto ikugwiritsa ntchito electromagnetic DPRV, ikani multimeter mu AC mode.
• Munthu wina ayenera kuyatsa choyatsira potembenuza kiyi mu loko popanda kuyatsa injini.
• Payenera kukhala voteji mu dera. Lumikizani probes ya multimeter ku "nthaka" (chinthu chilichonse chachitsulo cha injini yoyaka mkati), ndikulumikiza chachiwiri ndi mawaya a sensa ya camshaft. Kusowa kwaposachedwa pamawaya onse kukuwonetsa vuto mu waya wopita ku sensa.
• Uzani munthu amene ali m'galimoto kuti ayatse injini.
• Gwirani kafukufuku wina wamamita ku waya umodzi wa cholumikizira cha DPRV, chachiwiri ndi china. Makhalidwe adzawonekera pazenera la chipangizocho, chomwe chiyenera kufananizidwa ndi zowerengera zogwiritsira ntchito zomwe zaperekedwa mu malangizo ogwiritsira ntchito galimoto. Monga lamulo, zowonetsera pazenera zimasiyana pakati pa 0,3-1 volts.
• Kusowa kwa chizindikiro kumawonetsa kuwonongeka kwa sensor ya camshaft.

Momwe mungayimbire camshaft sensor 3 pini?

Kuzindikira kwa DPRV yamawaya atatu:

1. Pezani mawaya amagetsi, waya wapansi ndi mawaya achidziwitso (gwiritsani ntchito buku lokonzekera), kenako zindikirani kukhulupirika kwa mawaya omwe amapita ku sensa. Multimeter iyenera kusinthidwa kukhala DC mode.
2. Munthu wina ayenera kuyatsa choyatsira popanda kuyambitsa injini yoyaka mkati.
3. Timagwirizanitsa kafukufuku wakuda wa multimeter ku "nthaka" (gawo lililonse lachitsulo la injini yoyaka mkati), ndi yofiira ndi waya wamagetsi wa DPRV. Zotsatira zomwe zapezedwa ziyenera kufananizidwa ndi deta kuchokera ku malangizo ogwiritsira ntchito.
4. Wothandizira ayenera kuyambitsa ICE.
5. Gwirani kafukufuku wofiyira wa ma multimeter ku waya wolumikizira wa DPRV, ndikulumikiza chofufuza chakuda ku waya wapansi. Pakachitika kulephera kwa sensa, voteji idzakhala yotsika kuposa momwe tafotokozera m'buku lokonzekera. Zimachitika kuti multimeter sikuwonetsa kalikonse, zomwe zikuwonetsanso kulephera kwa sensa.
6. Chotsani DPRV ndikuzindikira zomwe zili ndi zolakwika zamakina kapena kuipitsidwa.

Sensor ya camshaft ndi chida chosavuta koma chofunikira, chomwe chimagwira ntchito yoyenera ya injini yoyaka mkati. Choncho, pozindikira zizindikiro za kulephera kwake, ndi bwino kuchita njira zoyenera zowunikira mwamsanga. Iwo ndi osavuta, ndipo ngakhale novice, mwini galimoto wosadziwa angathe kuwagwira.
