The Influence of Different Frequencies in the Turbulence on Early Flame Development in a Spark Ignition Engine

Johansson, Bengt LU (1994) SAE International Congress and Exposition, 1993 In SAE Technical Paper Series
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)
