Abstract

PURPOSE:To more accurately detect the true running conditin (knocking) of an engine and substantially improve the consumption of fuel and output of the engine, by performing the feedback control of ignitin time with good response while detecting the average level of knocking. CONSTITUTION:Only the component of knocking frequency is picked up by a band- pass filter 2 from the detection output of a sensor 1 for detecting the knocking of the engine. The level of the knocking is compared with an upper limit value and a lower limit value by an upper limit comparator 5 and a lower limit comparator 6. The average level of the knocking is detected on the basis of the outputs of the comparators 5, 6 to control the ignition time.
