Abstract: A system for simultaneously and quantitatively measuring the detonation and preignition in an internal combustion engine by evaluating the pressure variations in an engine cylinder for a given time after peak pressure in the cylinder and by evaluating a signal having frequency proportional to engine speed for a period between the occurrence of an ignition signal and peak pressure.
