cold start speed control scheme for SI engine-model-based cold-start speeed control scheme for spark ignition engines

The easy availability, lower well-to-wheel emissions, and relative ease of use associated with existing engine technology have made ethanol and ethanol-gasoline blends a viable alternative to gasoline for spark-ignition (SI) engines. The lower energy
