Yogwira ku Ford mafuta kuthamanga kachipangizo 55PP22-01 9307Z521A

Samalani mfundo zotsatirazi pakuyesa kwa ECU:

① Zimitsani choyatsira: chotsani pulagi ya ECU. ② Yatsani chosinthira choyatsira: gwiritsani ntchito multimeter kuti muwone mphamvu ya ECU. Mpweya pakati pa mapini 2 ndi 3 a pulagi ya ECU ndi magetsi pakati pa mapini 1 ndi 2 sayenera kukhala osachepera 11V, apo ayi, yang'anani dera.

2) Kuzindikira sensa yoziziritsa kuzizira ① Kuyang'anira mawaya: Zimitsani choyatsira ndikuchotsa pulagi yamabowo 4 ya sensor yoziziritsa kutentha, monga momwe chithunzi 2-36 chikusonyezera. Onani ngati pali dera lotseguka muwaya pakati pa dzenje lachitatu la pulagi ya 4-bowo ya sensor yoziziritsa kutentha ndi dzenje la 53 la socket ya ECU (kukana kwa waya kuyenera kukhala kwakukulu kuposa 1.5Ω), komanso ngati waya amafupikitsidwa mpaka pamtengo wabwino wamagetsi (kukana kuyenera kukhala kosatha). Onani ngati pali dera lotseguka kutsogolo pakati pa dzenje loyamba la pulagi ya 4-hole ya sensa yoziziritsa kutentha ndi dzenje la 67 la socket ya ECU (kukana kotsogolera sikuyenera kukhala kwakukulu kuposa 1.5Ω). ② Kuyang'anira magwiridwe antchito: Zimitsani chosinthira choyatsira, chotsani sensa yoziziritsa kuzizira, ikani choziziritsa kuzizira mu kapu yamadzi, ndipo gwiritsani ntchito ma multimeter kuti muwone kukana pakati pa zikhomo 1 ndi 3 za sensor yoziziritsa kutentha. Miyezo yofananira ya kutentha kwa madzi ndi kukana iyenera kukumana ndi zomwe zikuwonetsedwa mu Table 2-19. Table 2-19 Table of Temperature ndi Kukaniza kwa Coolant Temperature Sensor

3) Samalani mfundo zotsatirazi mukamazindikira sensor ya crankshaft (sensor liwiro la injini): ① Zimitsani chosinthira choyatsira: chotsani pulagi yoyera ya 3-hole ya sensor ya crankshaft (sensor liwiro la injini). ② Onani kukana pakati pa mapulagi: Monga momwe tawonetsera pa Chithunzi 2-37, kukana pakati pa mabowo 1 ndi 3 (nthaka) ndi pakati pa mabowo 2 ndi 3 (nthaka) kuyenera kukhala kosatha. Onani kukana pakati pa pini 1 ndi pini 2 ya sensa, yomwe iyenera kukhala 450 ~ 1000 Ω. Mfundo yogwiritsira ntchito deta yowonjezereka nthawi zambiri imatulutsa chizindikiro cha pulse (pafupifupi sine wave kapena rectangular wave). Njira zoyezera liwiro lozungulira la chizindikiro cha pulse zimaphatikizapo: njira yophatikizira pafupipafupi (ndiko kuti, njira yosinthira F / V, yomwe zotsatira zake zachindunji ndi voteji kapena pakalipano) ndi njira yogwiritsira ntchito pafupipafupi (yomwe zotsatira zake mwachindunji ndi digito).

Muukadaulo wamakina, pali miyeso yambiri ya liwiro lozungulira, ndipo liwiro la mzere nthawi zambiri limayesedwa mosalunjika ndi liwiro lozungulira. DC tachogenerator imatha kusintha liwiro lozungulira kukhala chizindikiro chamagetsi. Tachometer imafuna mgwirizano wa mzere pakati pa voteji yotulutsa ndi liwiro lozungulira, ndipo imafuna kuti voteji ikhale yotsetsereka komanso nthawi ndi kukhazikika kwa kutentha kukhala kwabwino. Tachometer imatha kugawidwa m'mitundu iwiri: mtundu wa DC ndi mtundu wa AC. Makina othamanga a rotary amalumikizana mwachindunji ndi chinthu chosuntha. Pamene chinthu chosuntha chikukhudzana ndi rotary speed sensor, kukangana kumayendetsa chogudubuza cha sensa kuti chizungulire. Sensa yozungulira ya pulse yomwe imayikidwa pa roller imatumiza ma pulse angapo. Kugunda kulikonse kumayimira mtunda wakutiwakuti, kotero kuti liwiro la mzerewu likhoza kuyezedwa. Mtundu wa electromagnetic induction, giya imayikidwa pa shaft yozungulira, ndipo mbali yakunja ndi koyilo yamagetsi. Kuzunguliraku kumachitika chifukwa cha kusiyana pakati pa mano a giya, ndipo voteji yosinthika imapezeka, ndiyeno liwiro lozungulira limawerengedwa. Sensa yothamanga ya rotary ilibe kukhudzana kwachindunji ndi chinthu chosuntha, ndipo filimu yowonetsera imamangiriridwa pamphepete mwa tsamba la impeller. Madzi amadzimadzi akamayenda, amayendetsa choyikapo chake kuti chizungulire, ndipo ulusi wa kuwala umatulutsa kuwala kamodzi kokha pozungulira cha choyikapo chake kuti apange chizindikiro cha kugunda kwamagetsi. Liwiro likhoza kuwerengedwa kuchokera ku chiwerengero cha ma pulses omwe apezeka.
