text: In order to quantify the impact of fueling changes on combustion, a sinusoidal perturbation with a 50-cycle time period was introduced on the injected fuel quantity, and the resultant effect of this perturbation on the cumulative heat release (HR) was characterized using a fast Fourier transform (FFT) of the HR of 5000 consecutive cycles.
