Cycle-To-Cycle Variations in S.I. Engines--The Effects of Fluid Flow and Gas Composition in the Vicinity of the Spark Plug on Early Combustion
Simultaneous measurements of early flame speed and local measurements of the major parameters controlling the process are presented. The early flame growth rate was captured with heat release analysis of the cylinder pressure. The local concentration of fuel or residual gas were measured with laser induced fluorescence (LIF) on isooctane/3-pentanone or water. Local velocity measurements were perfo
