The compression ratio of the engine is maintained constant at 9.5. Using various blends of gasoline-ethanol, at various operating conditions such as loads and speed under single plug mode of operations, the experiments are carried out in order to determine various cycle dispersion estimators, such as co-efficient of variation (COV) of IMEP. The five different loads considered for the experiments to be conducted are 0%, 25%, 50%, 75% and 100%.
