Combustion Process in a Spark Ignition Engine: Dynamics and Noise Level Estimation

open access: yes, 2003
We analyse the experimental time series of internal pressure in a four cylinder spark ignition engine. In our experiment, performed for different spark advance angles, apart from usual cyclic changes of engine pressure we observed oscillations.

Holes and chaotic pulses of traveling waves coupled to a long-wave mode

open access: yes, 1997
Localized traveling-wave pulses and holes, i.e. localized regions of vanishing wave amplitude, are investigated in a real Ginzburg-Landau equation coupled to a long-wave mode. In certain parameter regimes the pulses exhibit a Hopf bifurcation which leads
