Figure 3

Comparison between (a) in-cylinder static pressure and (b) acoustic pressure for a single-cylinder diesel engine. For the acoustic pressure, the gray and black lines show measured and filtered (from 1.1 to 2.9 kHz and 1.9 to 2.1 kHz) acoustic pressures to minimize influence from the dynamometer used in the experiments.
