The Influence of Different Frequencies in the Turbulence on Early Flame Development in a Spark Ignition Engine
(1994) SAE International Congress and Exposition, 1993- Abstract
- Two-components cycle-resolved Laser Doppler
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... (More) - Two-components cycle-resolved Laser Doppler
