In this paper we study the fluctuations of mean indicated pressure (MIP) in a diesel engine.
Using recurrence plots, recurrence quantification analysis and continuous wavelet …

The coefficient of covariation (COV) of the in-cylinder pressure is determined on each crank
angle of a number of cycles, in the case of a natural gas feed SI engine operating under lean …

The characterization of knock intensity distributions can provide useful insights into the
process and help to improve knock control system designs. In this paper, an extensive …

Using a continuous wavelet transform we have analyzed the cycle-to-cycle variations of
pressure in an internal combustion engine. The time series of maximum pressure variations …

Current practices of condition assessment in large marine engines are largely based on the
measurement of cylinder pressure using external kits, which poses challenges due to …

Cyclic combustion variability (CCV) is an undesirable characteristic of spark ignition (SI)
engines, and originates from variations in gas motion and turbulence, as well as from …

We analyze 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 the …

Traditional processing of knock signals reduces each recorded time history to a single scalar
knock intensity metric for each engine firing, thereby losing all information relating to the …

Using multifractal and statistical analyses, we have investigated the complex dynamics of
cycle-to-cycle heat release variations in a spark ignition engine. Three different values of the …

We analyse the combustion process in a spark ignition engine using the experimental data
of an internal pressure during the combustion process and show that the system can be …
