Abstract

PURPOSE: To realize a small-size and light-weight device with a high accuracy and high reliability, by applying the current proportional to the rotational frequency of the engine and the magnetic flux of the magnetic flux density which varies in proportional to the intake voltage of the intake manifold to the hall device and then displaying the fuel consumption factor on the display unit.
CONSTITUTION: The current IH proportional to the rotational frequency N is supplied to the Hall element 2 from the rotation detector 1 and by the rotation of the engine. On the other hand, the current proportional to the intake pressure P of the intake manifold which is generated via the intake detector 5 is supplied to the coil 7 via the amplifier 6. As a result, the magnetic flux of the magnetic flux density B proportional to the P is applied to the Hall element 2. The Hall element 2 supplies the Hall voltage proportional to the BIH to the driving circuit 3, and thus the fuel consumption factor proportional to the product of the rotational frequency and P is displayed on the display unit 4 by the output of the circuit 3. In this way, a small-size and light-weight structure is realized for the device with a high accuracy and high reliability.
