摘要：

An average energy method for quantifying knock intensity has been developed with a shifting window period; this is called the logarithmic knock intensity (LKI). To establish the engine knock conditions, a statistical analysis has been undertaken in real-time and a 1000-cycle LKT mean has been recommended as a proper criterion for defining the knock intensity. A method for eliminating the speed dependence of the LKI has also been developed. Derived from the above method, a multi-microprocessor based Knock Detector with LCD and LED displays and a D/A output has been developed. (C) 2001 Elsevier Science Ltd. All rights reserved.
