A system is disclosed through which knocking in an internal combustion engine is quantitatively measured by detecting engine vibrations with an accelerometer, transmitting the accelerometer signal to an elaboration network including an amplifier and a filter, transmitting an ignition pulse to a control network, transmitting the output from the elaboration network through a gate only during coincidence of a signal from the control network, the output of the control network corresponding to the angle of revolution of the crankshaft during which knocking usually occurs, and detecting the output signal from the gate.
