Summary:

An electronic phase-lock loop system is described which acts as an FM demodulator to extract the combustion/compression acceleration/deceleration fluctuations in the angular crankshaft velocity from an optical encoder signal. Further processing can provide roughness detection with a second phase-lock loop, and other similarly useful engine control or diagnostic parameters
