Abstract

A method with its corresponding apparatus, for measuring the contribution of relative power and the relative compression of each cylinder in an internal combustión engine, equipped with a spark ignition device connected to each cylinder, comprising the steps of Generating a series of voltage pulses wherein each pulse has a duration equivalent to the duration of the ignition voltage of one of said spark ignition devices, Producing from said series of pulses a first signal indicative of the time elapsed between the initiation of the voltage impulse for each cylinder and the initiation of the voltage impulse for the next cylinder, Producing, from said series of pulses, second and third indicative signals, respectively, of the time duration of the voltage pulse for each cylinder and the time elapsed between the completion of the voltage pulse for each cylinder and the initiation of the pulse of tension for the next cylinder, And computing, from said first, second and third signals, the relative power contribution and the relative compression for each cylinder.
