The combustion characteristics of eight cylinders, four valves per cylinder racing engine have been studied by using flame chemiluminescence sensors. The time-series chemiluminescence of OH^*, CH^*, and C^*_2 were measured by optical filters and photomultipliers. The flame emissivities and a pressure signal were obtained simultaneously. And the local flame characteristics of each cylinder were calculated. Then, we analyzed. Cycle-to-cycle and cylinder-to-cylinder variations of local air fuel ratio and flame propagation speed were investigated with changing engine operating conditions, and the differences of these flame characteristics between cylinders were also discussed.
