| In this paper we analyze the cycle-to-cycle variations of peak pressure p max and peak pressure angle α pmax in a four-cylinder spark ignition engine. We examine the experimental time series of p max and α pmax for three different spark advance angles. Using standard statistical techniques such as return maps and histograms we show that depending on the spark advance angle, there are significant differences in the fluctuations of p max and α pmax . We also calculate the multiscale entropy of the various time series to estimate the effect of randomness in these fluctuations. Finally, we explain how the information on both p max and α pmax can be used to develop optimal strategies for controlling the combustion process and improving engine performance. |
