ABSTRACT:
An automobile fuel gauge is used for an automobile wherein the operation of an electromagnetic fuel injection valve is controlled by a control signal supplied from an electronic fuel injection control system, thereby regulating an amount of fuel supplied to an engine cylinder. The fuel gauge includes a counter circuit for counting pulse signals included in the control signal and related to the opening of the electromagnetic fuel injection valve. The total length of time for which the electromagnetic fuel injection valve is opened is measured from the number of said central pulse signals issued, thereby determining the amount of fuel supplied to the engine cylinders through the electromagnetic fuel injection valve thus measuring the amount of consumed fuel.
