ABSTRACT:
An arrangement for indicating the on-going fuel consumption of an operating internal combustion engine in a motor vehicle having a multi-stage transmission. An engine operating parameter indicative of the quantity of fuel being supplied to the engine per engine revolution, is sensed or detected, and a signal representative of the sensed parameter is transmitted to an indicating instrument. The signal is modulated, furthermore, as a function of the currently engaged stage of the transmission. The modulating action may be carried out by a pressure transducer and the signal may be transmitted through a passage connecting the output of the transducer with the indicating instrument. The sensing procedure may be carried out through another passage connecting an input of the transducer with the intake manifold of the engine downstream of the throttle valve.
