ABSTRACT:
A fuel flow rate measuring apparatus for an internal combustion engine is capable of achieving cost reduction as well as measuring the flow rate of fuel with high accuracy over an entire fuel flow rate range. The apparatus includes an injection pulse width detection part for detecting an injection pulse width to drive injectors, an engine speed detection part for detecting the rotational speed of the engine, an injector driving frequency detection part for detecting an injector driving frequency per revolution of the engine from the rotational speed, a fuel injection amount characteristic setting part for setting at least one fuel injection amount characteristic corresponding to the injection pulse width, and a fuel flow rate detection part for detecting the flow rate of fuel per unit time from the injection pulse width, the injector driving frequency, and the fuel injection amount characteristic.
