ABSTRACT:
A process and apparatus for electronic angle of advance correction in response to pinging and engine charge, which calculates and adjusts the optimization of the advance of an internal combustion engine by detecting pinging, including an integrator with an integration capacitor, and a microprocessor including in particular a counter connectable to a pressure transducer, a calculating stage for calculating the average integrated noise value, a calculating stage for calculating a pinging detection threshold, and a calculating stage for calculating the angle decrementing value to be transmitted to an output stage.
