  • Method for determining a measurement value proportional to the compression of an internal combustion engine
    Patent number: 4144746
    Abstract: A method for determining a measurement value proportional to the compression of an internal combustion engine, derived from the starter current, in which the a-c component of the starter current is integrated over the time between successive current minima and the difference between an integration value averaged over an engine cycle and integration values for individual cylinders obtained between succeeding current minima, is added, with the sign reversed, to the integration value for the next-following cylinder.
