Theoretically speaking, we can achieve the detection and control of the parameters of engine knock and ms-PULSE etc effectively and accurately by analysis the ionic current signals. But in actual application, it is difficult to detect the ionic current signals because of the interference of high pressure from high-tension ignition system. At present, the application of ionic current signal in the detection and control of engine knock is still in the initial early stages. We optimized the signal acquisition system, interference the suppression, achieve the effective detection of ionic current signal in the tests we mentioned in the topic, and then, we analysis and compared the character of ionic current and cylinder pressure signals we collected under different working conditions, exploration and testing is carried out for the further recognition and control of engine knock using the ionic current signals.
