Momwe mungayang'anire sensor ya PMH?

Sensor Top Dead Center (TDC) yagalimoto yanu imatsimikizira malo mfuti... Kenako imatumiza chidziwitso ku injini ECU, yomwe imatha kudziwa jekeseni wamafuta omwe amafunikira kuthamanga. Ngati sensa ya TDC ili ndi vuto, mudzakhala nayo mavuto oyambitsa... Umu ndi momwe mungayang'anire sensor ya PMH.

Zakuthupi:

• Kulowa
• Chiffon
• Zida
• Voltmeter
• oscilloscope
• Multimeter

🔎 Khwerero 1: Yang'anani mwatsatanetsatane sensa ya TDC.

Kuti muyese sensa ya TDC, muyenera kuyipeza kaye. Sensa ya TDC, yomwe imatchedwanso crankshaft sensor, ili pa crankshaft ndi flywheel pansi pa injini. Chotsani zomangira zosungira kachipangizo ndikudula chingwe pakati pa sensa ya TDC ndi injini ya ECU.

Tiyeni tiyambe ndi cheke chosavuta cha sensor ya TDC:

• Onetsetsani kuti sichikutsekedwa;
• Onetsetsani kuti kusiyana kwa mpweya sikuwonongeka;
• Yang'anani pakati pa sensa ya TDC ndi injini ECU.

Mutha kutenganso mwayi kuti muwone sensor yanu ya PMH pogwiritsa ntchito kampasi. Ndi mtundu wa mayeso oyambira pang'ono, amatha kukuuzani ngati sensor ikugwira ntchito. Zowonadi, sensor ya TDC yochititsa chidwi imakhala ndi maginito omwe amazindikira zinthu zachitsulo.

• Ngati sensa ikukoka kumpoto, imagwira ntchito;
• Ngati amakokera kumwera, ndiye HS!

Chenjezo, mayesowa sagwira ntchito ndi sensa yogwira ntchito ya PHM, yomwe imadziwikanso kuti Hall effect. Sensa yogwira ya TDC ilibe gawo lamagetsi chifukwa ndi lamagetsi kwathunthu. Imapezeka, makamaka, pamainjini aposachedwa kwambiri.

💧 Gawo 2. Yeretsani sensor ya TDC.

Kuti zigwire ntchito zonse, sensa ya TDC siyenera kuipitsidwa. Umu ndi momwe mungayeretsere sensa ya TDC musanayiyang'ane:

• Utsi WD 40 kapena mafuta ena aliwonse pa sensa thupi;
• Pukutani mofatsa ndi nsalu yoyera mpaka dothi ndi dzimbiri zichotsedwe.

⚡ Gawo 3. Yang'anani chizindikiro cha magetsi ndi kukana kwa sensa ya TDC.

Kenako mudzayang'ana chizindikiro chamagetsi ndi kukana kwa sensa yanu ya TDC. Komabe, samalani ndi mtundu wa sensa yomwe ikufunsidwa: ngati muli ndi sensa yogwira ya TDC, mulibe kukana kuyesa. Mutha kuyang'ana chizindikirocho kuchokera ku Hall effect TDC sensor.

Gwiritsani ntchito ohmmeter kapena multimeter kuti muwone sensor ya TDC yochititsa chidwi. Lumikizani multimeter pazotulutsa za sensa ya TDC ndikuwona mtengo womwe wawonetsedwa. Zimatengera wopanga magalimoto. Mulimonsemo, idzakhala pakati pa 250 ndi 1000 ohms. Ngati ndi ziro, pali dera lalifupi kwinakwake.

Kenako yang'anani chizindikiro chamagetsi. Gwiritsani ntchito oscilloscope kuyesa masensa a Hall effect TDC omwe ali ndi mawaya a 3 (zabwino, zoipa ndi chizindikiro). Zinakhala zamakona anayi. Kwa sensa yogwira ya TDC, oscilloscope ndi sinusoidal.

Yang'anani chizindikiro chotuluka ndi voltmeter. Lumikizani cholumikizira cha sensa ya TDC ndikulumikiza voltmeter ku chotulutsa cha AC. Zotsatira za sensa yabwino ya TDC ili pakati pa 250 mV ndi 1 Volt.

👨‍🔧 Khwerero 4. Thamangani zowunikira zamagetsi.

Komabe, njira yodalirika komanso yodalirika yowonera sensa ya TDC, matenda amagetsi, palibe aliyense. Zowonadi, ndiye kuti muyenera kukhala ndi vuto lodziwira matenda komanso pulogalamu yotsatiridwa ndi autodiagnostic. Komabe, chida ichi ndi chokwera mtengo kwambiri ndipo nthawi zambiri chimakhala cha akatswiri amakanika okha. Koma ngati ndinu makanika, palibe chomwe chingakulepheretseni kuyika ndalama.

Pulogalamu yowunikira imabweretsanso cholakwika chomwe chikuwonetsa momwe vutolo lilili ndi sensa ya TDC (mwachitsanzo, palibe chizindikiro). Muthanso kuyendetsa zowunikira poyambira kuti muwone, ndikukhazikika kokhazikika, magwiridwe antchito oyenera a sensa.

🔧 Khwerero 5: Sonkhanitsani sensor ya TDC

Mukayang'ana sensor ya TDC, muyenera kuyiphatikizanso. Ikani sensor flat, sungani screw fixing. Lumikizaninso cholumikizira cha sensa, ndiye yambitsani galimotoyo kuti muwonetsetse kuti ikugwira ntchito bwino.

Ndizomwezo, mukudziwa kuyesa sensor ya PMH! Koma, monga momwe mwadziwira kale, mayeso abwino kwambiri akadali amagetsi amagetsi, zizindikiro zomwe zimakulolani kuti mudziwe chomwe chili vuto. Kufufuza ndi kusintha PMH sensorchifukwa chake yerekezerani magalasi ozungulira ndikuyika galimoto yanu ku zabwino!
