We investigate the nonlinear time series of Indicated Mean Effective Pressure (IMEP) of the spark ignition engine cyclic combustion process of a natural gas. By applying the embedding theorem and the recurrence plots technique, we show changes in the engine dynamics for different equivalence ratios. Especially, we provide arguments for intermittency behaviour.

Zbadano nieliniowe przebiegi czasowe Średniego Ciśnienia Indykowanego cyklicznego procesu spalania w silniku spalinowym zasilanym gazem naturalnym. Stosując twierdzenie o zanurzeniu oraz technikę wykresów rekurencyjnych, pokazano istotne różnice w dynamice silnika przy zmianie składu mieszanki paliwa wyrażonej wartością współczynnika równowagowego. W szczególności podano argumenty przemawiające za występowaniem zjawiska intermitencji.
