I-Ford Jaguar Fuel Common Rail Pressure Sensor 8W839F972AA

1. Ukuhlolwa komugqa wangaphandle

Linganisa amanani okumelana phakathi kwetheminali No.1 kanye netheminali engu-A08, itheminali No.2 kanye netheminali engu-A43, kanye netheminali No.3 kanye netheminali A28 nge-multimeter ukuze kwahlulele ukuthi kukhona yini iphutha lesekethe elifushane noma iphutha elivulekile kwisekethe yangaphandle.

2. Isilinganiso senzwa kagesi

Vala iswishi yokubasa, ukhiphe ipulaki lenzwa yokucindezela komzila ovamile, bese uvula iswishi yokubasa. Linganisa i-voltage phakathi kokuphela kwe-No.3 yepulaki yenzwa kanye nomhlabathi, i-voltage phakathi kokuphela kwe-No.2 kanye nomhlabathi kufanele ibe ngu-0.5V, kanti i-voltage phakathi kokuphela kwe-No.1 nomhlaba kufanele kube ngu-0V. Ngaphansi kwezimo ezijwayelekile, i-voltage ekupheleni kwe-No.2 kufanele ikhule ngokunyuka kwe-throttle, ngaphandle kwalokho kungahlulelwa ukuthi ukuphuma kwesignali yephutha lenzwa kungavamile.

3. Ukutholwa kokusakaza kwedatha

Funda ukugeleza kwedatha yesistimu yokuphakela uphethiloli wenjini ngethuluzi lokuxilonga elikhethekile, thola isimo sokungenzi lutho, ukushintsha komfutho kawoyela ngokunyuka kwe-throttle, futhi wahlulele ukuguqulwa kwamandla kagesi wenzwa yomfutho wesitimela.

(1) Uma izinga lokushisa elipholile lenjini kadizili lifinyelela ku-80 ℃ futhi injini kadizili isebenza ngesivinini esingenzi lutho, i-voltage ephumayo yenzwa yomfutho wesitimela kufanele ibe ngu-1V, kanye nomfutho wesitimela wesistimu kaphethiloli kanye nenani elibekiwe umfutho wesitimela womabili cishe u-25.00MPa. Inani lokusetha ingcindezi kajantshi lisondele kakhulu kunani lomfutho wesitimela wesistimu kaphethiloli.

(2) Lapho unyathela i-accelerator pedal kancane kancane futhi ukhuphula ijubane lenjini kadizili, inani ledatha yesistimu yokucindezela ujantshi liyakhula kancane kancane, futhi amanani aphezulu okucindezela kukajantshi, inani lokusetha ingcindezi kajantshi kanye nomfutho wesitimela wangempela wohlelo lukaphethiloli kungu-145.00MPa , kanye ne-voltage ephezulu yokuphumayo yenzwa yomfutho wesitimela ngu-4.5V V. Ukugeleza kwedatha okulinganiselwe (okungokwereferensi kuphela) kuboniswa kuthebula elingezansi.

4, iphutha elivamile lomkhuba

Lapho inzwa evamile yokucindezela komzila wesitimela ihluleka (njengokukhipha i-plug), injini ye-diesel ingase ingaqali, injini izothuthumela ngemva kokuqala, isivinini esingenzi lutho sizobe singazinzile, kuzophuma intuthu eningi emnyama ngesikhathi sokusheshisa, futhi ukusheshisa kuyoba buthaka. Amamodeli ahlukene asebenzisa amasu ahlukene okulawula injini. Amaphutha athile ayahlukahluka kuye ngamamodeli.

(1) Uma inzwa yomfutho wesitimela evamile ihluleka, injini ye-diesel ayikwazi ukuqaliswa.

(2) Lapho inzwa yomfutho wesitimela evamile ihluleka, injini kadizili ingaqala futhi isebenze ngokujwayelekile, kodwa injini ilinganiselwe ngetorque.

(3) Amakhodi wephutha avamile lapho inzwa yokucindezela kojantshi evamile ihluleka (ilahlekile),

① injini ayikwazi ukuqala futhi isebenze: P0192,P0193;;

② i-signal drift, umkhawulo we-torque yenjini: P1912, P1192, P1193.
