Me pehea te tirotiro i te puoro PMH?

Pūpara Pokapū mate runga (TDC) o to waka hei whakatau i te tuunga piston... Ka tukuna atu enei korero ki te ECU miihini, ka taea te whakatau i te werohanga wahie e hiahiatia ana mo te tere. Mēnā he hē te pūoko TDC, ka whai koe raruraru whakaoho... Anei me pehea te tirotiro i te puoro PMH.

Material:

• Te kuhu
• Whakaahua
• Utauta
• Voltmeter
• oscilloscope
• Motuhake

🔎 Hipanga 1: Tirohia te pūoko TDC.

Hei whakamatautau i te pūoko TDC, me uru tuatahi koe. Ko te pūoko TDC, e kiia ana ko te pūoko crankshaft, kei runga i te crankshaft me te wira rere kei raro o te miihini. Tango i te tīwiri pupuri pūoko ka momotuhia te here i waenganui i te pūoko TDC me te pūkaha ECU.

Me timata ma te tirohanga tirohanga ngawari o te pukoro TDC:

• Me whakarite kia kaua e purua;
• Me mohio kei pakaru te hau hau;
• Tirohia te awhi i waenga i te pūoko TDC me te ECU miihini.

Ka taea hoki e koe te whai waahi ki te tirotiro i to puoro PMH ma te whakamahi i te kapee. He momo whakamatautau tuatahi, ka taea te korero ki a koe mena kei te mahi te puoro. Ae, he pukoro TDC inductive he papa autō ka kitea nga mea whakarewa.

• Mena kei te toia te pukoro ki te raki, ka mahi;
• Mena ka kumea e ia ki te tonga, he HS ia!

Whakatupato, kaore tenei whakamatautau e mahi me te pukoro PHM hohe, e mohiotia ana ko te awenga Hall. Ko te pūoko TDC hohe karekau he mara hiko na te mea he hikohiko katoa. Ka kitea, ina koa, i runga i nga miihini hou.

💧 Hipanga 2. Horoia te pūoko TDC.

Mo te mahi katoa, kaua e poke te pūoko TDC. Anei me pehea te horoi i te pukoro TDC i mua i te tirotiro:

• Mapuhia te WD 40 me etahi atu hinu ki runga i te tinana pukoro;
• Me ata horoia ki te kakahu ma kia tangohia katoatia nga paru me te waikura.

⚡ Hipanga 3. Tirohia te tohu hiko me te parenga o te pūoko TDC.

Na ka tirohia e koe te tohu hiko me te aukati o to puoro TDC. Heoi, kia tupato ki te ahua o te pukoro e patai ana: mena kei a koe he pukoro TDC kaha, karekau he atete ki te whakamatautau. Ka taea anake te tirotiro i te tohu mai i te Hall effect TDC sensor.

Whakamahia he inemita, inemita maha ranei hei tirotiro i te pukoro TDC. Tūhonohia he mita maha ki te putanga o te pūoko TDC ka tirohia te uara kua whakaatuhia. Kei runga i te kaihanga waka. Ahakoa he aha, ka noho i waenga i te 250 me te 1000 ohms. Mena he kore, he ara iahiko poto ki tetahi waahi.

Na ka tirohia te tohu hiko. Whakamahia he oscilloscope ki te whakamatautau i te Hall effect TDC sensor e 3 nga waea (he pai, he kino me te tohu). I puta he tapawha. Mo te pūoko TDC kaha, he sinusoidal te oscilloscope.

Tirohia te tohu whakaputa me te voltmeter. Momotuhia te tūhono pūoko TDC ka tūhonohia he mita hiko ki te putanga AC. Ko te hua o te pukoro TDC pai kei waenga i te 250 mV me te 1 Volt.

👨‍🔧 Hipanga 4. Whakahaerehia te tātari hiko.

Engari, ko te huarahi tino pono me te pono ki te tirotiro i te pukoro TDC, nga taatai ​​hiko, kaore i te waatea ki te katoa. Ae ra, me whiwhi koe i tetahi keehi tātaritanga me te rorohiko autodiagnostic e hono ana. Heoi, he tino utu tenei taputapu, a, i te nuinga o te waa na nga miihini ngaio anake. Engari mena he miihini koe, kaore he mea hei aukati i a koe ki te haumi.

Ka whakahokia e te rorohiko taatai ​​he waehere hapa e whakaatu ana i te ahua o te raruraru me te puoro TDC (hei tauira, kaore he tohu). Ka taea hoki e koe te whakahaere tātaritanga i te tiimatanga ki te mataki, me te kopikopiko tonu, te mahi tika o te pukoro.

🔧 Hipanga 5: Huihuia te pūoko TDC

Whai muri i te tirotiro i te pukoro TDC, me whakahiato ano. Tāutahia te pūoko papatahi, whakakoia te tīwiri whakatika. Tūhono anō i te kākahu pūoko, kātahi ka tīmatahia te waka kia tika te mahi.

Koina, e mohio ana koe ki te whakamatautau i te pukoro PMH! Engari, i te mea kua mohio koe, ko te whakamatautau pai tonu ko nga taatai ​​hiko, ko nga tohu e taea ai e koe te mohio he aha te raruraru. Hei tirotiro me whakakapi PMH pūokono reira whakatauritea nga karati huri noa me te tuku i to waka ki te hunga pai!
