Discuss the mechanism on how mixture composition (a type of fuel, overall

equivalence ratio, and an overall fraction of diluents) affects the cycle-to-cycle

variations (CCV) in SI engine. Describe the stage of combustion (sparking and

flame initiation, initial flame kernel development, and turbulent flame propagation) most affected by each parameter. Explain how each parameter can be

adjusted to minimize the CCV in SI engine.
