Isebenza kwi-Ford ye-fuel sensor sensor 55PP22-01 9307Z521A

Nika ingqalelo kula manqaku alandelayo kuvavanyo lwe-ECU:

① Cima iswitshi yokulayita: susa iplagi yeECU. ② Vula i-ignition switch: sebenzisa i-multimeter ukujonga ukunikezelwa kwamandla e-ECU. I-voltage phakathi kwezikhonkwane ze-2 kunye ne-3 zeplagi ye-ECU kunye ne-voltage phakathi kwezikhonkwane ze-1 kunye ne-2 akufanele zibe ngaphantsi kwe-11V, ngaphandle koko, jonga isiphaluka.

2) Ukubonwa kwesivamvo sobushushu obupholileyo ① Ukuhlolwa kweengcingo: Cima isitshixo somlilo kwaye ususe iplagi enemingxuma emi-4 yesivamvo sobushushu esipholileyo, njengoko kubonisiwe kuMfanekiso 2-36. Khangela ukuba kukho isiphaluka esivulekileyo kwintambo phakathi komngxuma we-3 weplagi ye-4-hole ye-sensor yeqondo lokushisa elipholileyo kunye nomngxuma we-53 we-socket ye-ECU (ukumelana nocingo akufanele kube mkhulu kune-1.5Ω), nokuba ingaba ucingo lufutshane-lujikelezwe kwisibonda esilungileyo sonikezelo lwamandla (ukuchasana kufuneka kungapheli). Khangela ukuba kukho isiphaluka esivulekileyo kwi-lead phakathi komngxuma wokuqala weplagi ye-4-hole ye-sensor yeqondo lokushisa elipholileyo kunye ne-67th hole ye-socket ye-ECU (ukumelana okukhokelayo akufanele kube mkhulu kune-1.5Ω). ② Ukuhlolwa kokusebenza: Cima umtshini wokutshisa, susa inzwa yobushushu obupholileyo, ubeke inzwa yobushushu obupholileyo kwikomityi yamanzi, kwaye usebenzise i-multimeter ukubona ukuchasana phakathi kwezikhonkwane 1 kunye ne-3 zenzwa yobushushu obupholileyo. Amaxabiso ahambelanayo obushushu bamanzi kunye nokuchasana kufuneka ahlangabezane namaxabiso aboniswe kwiThebhile 2-19. ITheyibhile 2-19 eNxulumeneyo yeTheyibhile yoBubushushu kunye noKuxhathisa iSensom yoBubushushu obupholileyo

3) Nika ingqalelo kula manqaku alandelayo xa ubhaqa i-sensor yendawo ye-crankshaft (inzwa yesantya se-injini): ① Cima iswitshi yokucima: susa iplagi emhlophe enemingxuma emi-3 ye-sensor yendawo ye-crankshaft (inzwa yesantya se-injini). ② Khangela ukuchasana phakathi kweeplagi: Njengoko kuboniswe kwi-Figure 2-37, ukuchasana phakathi kwemingxuma ye-1 kunye ne-3 (umhlaba) kunye phakathi kwemingxuma ye-2 kunye ne-3 (umhlaba) kufuneka ingapheli. Jonga ukuchasana phakathi kwe-pin 1 kunye ne-2 ye-sensor, ekufuneka ibe yi-450 ~ 1000 Ω. Umgaqo osebenzayo wedatha eyandisiweyo ubukhulu becala uvelisa umqondiso wepulse (ingqimba yesine eqikelelwayo okanye i-rectangular wave). Iindlela zokulinganisa isantya esijikelezayo somqondiso we-pulse ziquka: indlela yokudibanisa i-frequency (oko kukuthi, indlela yokuguqula i-F / V, isiphumo sayo esithe ngqo yi-voltage okanye yangoku) kunye nendlela yokusebenza rhoqo (isiphumo sayo sidijithali).

Kwitekhnoloji ye-automation, kukho imilinganiselo emininzi yesantya sokujikeleza, kwaye isantya somgca sihlala silinganiswa ngokungangqalanga ngesantya sokujikeleza. I-DC tachogenerator inokuguqula isantya sokujikeleza sibe ngumqondiso wombane. I-tachometer ifuna unxibelelwano phakathi kombane ophumayo kunye nesantya sokujikeleza, kwaye ifuna amandla ombane wokuphuma abe ngumnqantsa kwaye ixesha kunye nokuzinza kobushushu kube kuhle. I-tachometer inokwahlulwa ngokubanzi ibe ziindidi ezimbini: uhlobo lwe-DC kunye nohlobo lwe-AC. Inzwa yesantya ejikelezayo inxibelelana ngokuthe ngqo nento ehambayo. Xa into eshukumayo idibene ne-rotary speed sensor, i-friction iqhuba i-roller ye-sensor ukuze ijikeleze. I-sensor ye-pulse ejikelezayo efakwe kwi-roller ithumela uchungechunge lwee-pulses. I-pulse nganye imele ixabiso elithile lomgama, ukwenzela ukuba isantya somgca sinokulinganiswa. Uhlobo lwe-electromagnetic induction, igiya ifakwe kwishaft ejikelezayo, kwaye icala langaphandle yicoil ye-electromagnetic. Ukujikeleza kubangelwa umsantsa phakathi kwamazinyo egiya, kwaye i-voltage eguqukayo yesikwere ifunyenwe, kwaye ke isantya sokujikeleza sibalwa. I-sensor yesantya ejikelezayo ayinakho ukudibanisa ngokuthe ngqo kunye nento ehambayo, kwaye ifilimu ebonakalisayo ifakwe kwi-blade edge ye-impeller. Xa ulwelo luhamba, luqhubela i-impeller ukuba ijikeleze, kwaye i-fiber optical idlulisela ukukhanya kanye ukujikeleza kwe-impeller ukuvelisa umqondiso we-pulse yombane. Isantya singabalwa ukusuka kwinani lee-pulses ezifunyenweyo.
