On the basic of numerical study we show the mechanism of translation from steady state to chaotic and hyperchaotic behavior. Additionally, the impact of parameter changes on the behavior of the system will be presented. Confirmation of our results are bifurcation diagrams, timelines, phase portraits, Poincare maps and largest Lyapunov exponent diagrams.enoscillatorbifurcation diagramphase portraitPoincare maposcylatordiagram bifurkacjiportret fazowymapa Poincareartykuł
