posted on 2017-10-31, 09:45 authored by Simon RobinsonHomogeneous charge combustion in a four stroke cycle spark-ignition engine was
studied using through-piston-photography with a gated-intensified CCD camera.
Analysis of computer stored multiple exposed flame front images was carried out for
various engine conditions, in conjunction with the test data and cylinder pressure signals.
Representative turbulence scales were inferred from the flame propagation and cylinder
pressure data. Fractal analysis of flame edge contours resulted in a fractal dimension
D3 in the range 2.12 to 2.23 corroborating data presented elsewhere. A correlation is
presented here between the standard deviation of peak cylinder pressure and the fractal
dimension D3.
