Abstract
A method of and an apparatus for measuring and displaying the output of an internal combustion engine of a vehicle while the vehicle is moving. An intake air flow quantity Q and a rotation speed N of the engine are calculated to determine an intake air quantity per revolution (Q/N), and provide a base output. At the same time, the method and apparatus detect a fuel flow quantity supplied to the engine, and depending on the fuel flow quantity and intake air flow quantity, calculate an air-fuel ratio by which the base output is corrected to provide an engine output to be displayed.
