Discuss the mechanism on how in-cylinder mixture motion (mean flow vector at

the spark plug gap vicinity, overall in-cylinder flow pattern, turbulence intensity,

and scale) affects the cycle-to-cycle variations (CCV) in SI engine. Describe the

stage of combustion most affected by each parameter and also explain how each

parameter can be adjusted to minimize the CCV in SI engine. Suggest the engine

design changes for minimization of cyclic combustion variability.
