摘要: A knocking detection method for internal combustion engines in which vibrations of the engine are detected by a vibration sensor and peak value during predetermined interval near top dead center each revolution is sampled. The stored number revolutions an average values obtained. Then ratio to calculated, ratios whose magnitude exceeds expressed terms rate or percentage with respect total ratios, i.e., engine. presence absence determined whether not above reference percentage.
