Stie cineva cum functioneaza (pe ce principiu) indicatorul de consum din bord ?

Cred ca pe baza de vacuum.

Eram curios ... Totusi, daca era pe baza de vacuum, ar fi trebuit sa aibe vreun furtunas, vreun senzor, ceva pe admisie. Parca nu am vazut asa ceva la mine. Ma gandesc daca nu cumva este controlat de ECU. -------------------- Life is too short to drive anything less than a BMW ...

Aproape sigur e pe baza computerului de injectie. El dicteaza timpii de deschidere ai injectoarelor => stie debitul mediu de benzina pe secunda (Q) calculat pe un interval mic delta_t. Apoi bordul stie viteza de deplasare a masinii in acel moment, de unde deduce cati metri (x) se parcurg in acel delta_t. Face o impartire Q/x si-ti da rezultatul pe ceas.
P.S. Asa vad eu lucrurile, n-am intrebat si nu m-am documentat nicaieri. Daca stiti altfel, spuneti. -------------------- Inline 6 in a 5-er 4 ever

 nu stiu daca vorbeai serios, dar chiar am facut o greseala:x e in metri pe secunda, nu metri/delta_t delta_t trebuie sa fie doar ceva intern, intervalul pe care se considera ca debitul de benzina si viteza de deplasare sunt constante. Cu cat delta_t e mai mic cu atat rezultatul final e mai aproape de adevar. -------------------- Inline 6 in a 5-er 4 ever
