The Influence of Different Frequencies in the Turbulence on Early Flame Development in a Spark Ignition Engine
Författare
Summary, in English
Velocimetry (LDV) measurements were performed with
high data rate to resolve the flow in a spark ignition
engine. The velocity measurements were then processed
with both a frequency and a time domain filtering
technique to obtain the level of turbulence at different
frequencies. Simultaneous cylinder pressure
measurements gave information of the duration of the
early flame development through a heat release
calculation. The initial combustion rate was correlated to
the turbulence at different frequencies and the results
showed a higher correlation for the high frequencies (4-6
kHz) when the engine was run at 700 rpm.
