More Information
Summary:A fuel consumption measuring apparatus for an internal combustion engine equipped with an electromagnetic fuel injection valve, comprising a fuel injection control means which calculates a proper value of fuel to be injected into the engine, and which then corrects this value in accordance with the characteristics of the electromagnetic fuel injection valve and controls the valve thereby, and a totalling means, which, in synchronization with the signals for controlling the valve, totals the values of the amount of fuel to be injected. In an embodiment, the totalling means is capable of subtracting a first predetermined value from the total held therein, and the apparatus further comprises a decision means which at regular time intervals judges whether the totalled value in the totalling means is greater than a second predetermined value or not; and, if it is, outputs an output pulse signal and also controls the totalling means to cause it to perform the subtraction.
