Improving the Efficiency of Power Generation Plants Based on Internal Combustion Engines

Abstract

This paper describes a method developed by the authors for the detection and estimation of knock intensity in the cylinders of internal combustion engines. The method is based on the spectral analysis of the ion current signal, which is detected within the combustion chamber of the engine. The method allows estimation of the total wave packet energy for different waves speed and frequency. The estimation results of wave’s energy arising in the normal and knock combustion to engine VAZ 2110 are also presented in the paper work.
