I-Ford Jaguar Fuel I-Fuel Common Rail Pressure Sensor 8W839F972AA

1. Ukuhlolwa komgca wangaphandle

Ukulinganisa amaxabiso okumelana phakathi kwe-terminal No.1 kunye ne-terminal A08, i-terminal No.2 kunye ne-terminal A43, kunye ne-terminal No.3 kunye ne-terminal A28 kunye ne-multimeter ukugweba ukuba kukho isiphaluka esifutshane okanye i-circuit yesiphaluka evulekileyo kwisiphaluka sangaphandle.

2. Umlinganiselo wombane woluvo

Cima iswitshi yokutshisa, ukhuphe iplagi yesixhobo soxinzelelo sikaloliwe esiqhelekileyo, kwaye uvule iswitshi yokutshisa.Ukulinganisa i-voltage phakathi kwe-No.3 ekupheleni kweplagi ye-sensor kunye nomhlaba, i-voltage phakathi kwe-No.2 ekupheleni kunye nomhlaba kufuneka ibe malunga ne-0.5V, kwaye i-voltage phakathi kwe-No.1 ekupheleni kunye nomhlaba kufuneka ibe yi-0V.Ngaphantsi kweemeko eziqhelekileyo, i-voltage kwi-No.2 ekupheleni kufuneka inyuke ngokunyuka kwe-throttle, ngaphandle koko inokugwetywa ukuba i-sensor ye-fault signal output ayiqhelekanga.

3. Ubhaqo lomjelo wedatha

Funda ukuhamba kwedatha yenkqubo yokubonelela nge-injini ye-injini ngesixhobo esikhethekileyo sokuxilonga, ukubona imeko engasebenziyo, utshintsho lwe-oyile yoxinzelelo kunye nokunyuka kwe-throttle, kwaye ugwebe utshintsho lombane wesiphumo senzwa yoxinzelelo lukaloliwe.

(1) Xa ubushushu bokupholisa benjini yedizili bufikelela kuma-80 ℃ kwaye injini yedizili ibaleka ngesantya esingasebenziyo, amandla ombane ophuma kwinzwa yoxinzelelo lukaloliwe kufuneka abe malunga ne-1V, kunye noxinzelelo lukaloliwe lwenkqubo yamafutha kunye nexabiso elimiselweyo Uxinzelelo lukaloliwe zombini malunga 25.00MPa.Ixabiso lokumisela uxinzelelo lukaloliwe lisondele kakhulu kwixabiso loxinzelelo lukaloliwe lwenkqubo yamafutha.

(2) Xa unyathela kwi-pedal ye-accelerator ngokuthe ngcembe kwaye unyusa isantya se-injini ye-diesel, ixabiso ledatha yenkqubo yoxinzelelo kaloliwe liyenyuka ngokuthe ngcembe, kwaye amaxabiso aphezulu oxinzelelo lukaloliwe, ixabiso lokubeka uxinzelelo lukaloliwe kunye noxinzelelo lwe-rail yangempela ye-fuel system yi-145.00MPa , kunye ne-voltage ephezulu yokukhupha i-sensor yoxinzelelo lukaloliwe yi-4.5V V.

4, impazamo eqhelekileyo

Xa i-sensor yoxinzelelo kaloliwe eqhelekileyo ihluleka (njengokukhupha iplagi), injini ye-diesel isenokungaqali, injini iya kungcangcazela emva kokuqala, isantya esingenamsebenzi siya kungazinzi, umsi omninzi omnyama uya kukhutshwa ngexesha lokukhawuleza, kwaye ukukhawuleza kuya kuba. buthathaka.Iimodeli ezahlukeneyo zisebenzisa iindlela ezahlukeneyo zokulawula injini.Iimpazamo ezithile ziyahluka ukusuka kwimodeli ukuya kwimodeli.

(1) Xa isivamvo soxinzelelo sikaloliwe esiqhelekileyo singasebenzi, injini yedizili ayinakuqalwa.

(2) Xa isivamvo soxinzelelo sikaloliwe esiqhelekileyo sisilela, i-injini ye-diesel inokuqalisa kwaye isebenze ngokuqhelekileyo, kodwa i-injini ilinganiselwe kwi-torque.

(3) Iikhowudi zempazamo eziqhelekileyo xa isivamvo soxinzelelo sikaloliwe esiqhelekileyo singaphumeleli (silahlekile),

① injini ayikwazi ukuqalisa kwaye isebenze: P0192,P0193;

② ukuhanjiswa komqondiso, umda we-torque ye-injini: P1912, P1192, P1193.
