Claims

[Scope of utility model registration request]

The cumulative or average first fuel consumption amount is detected based on a fuel injection pulse having a pulse width corresponding to the fuel injection amount obtained from the electronic fuel injection device control circuit 1 that controls the fuel injection amount supplied to the engine. a first fuel consumption amount detection circuit 2, 3, which detects the liquid level in the fuel tank and detects a cumulative or average second fuel consumption amount based on a change in the liquid level. Consumption detection circuit 8.9. 10. 1
1, and the second fuel consumption detection circuit of the first fuel consumption detection circuits 2 and 3 compares the first fuel consumption amount and the second fuel consumption amount under the same detection conditions. 8.9.
10. a correction value calculation circuit 12 that calculates a detection error when using 11 as a reference and calculates a correction amount corresponding to the error;
A storage circuit 14 that stores the correction amount obtained from the correction value calculation circuit, and a correction circuit 13' that corrects the first fuel consumption amount based on the correction amount, the first fuel consumption amount corrected by the correction circuit. 1. A fuel consumption measurement circuit characterized in that the fuel consumption of No. 1 is output as a measurement output.
