SI2-4 Evaporation and Mixture Formation Processes of Ethanol/Gasoline Blended Fuel Spray Injected by Hole-Type Injector for D.I. Gasoline Engine(SI: Spark-Ignition Engine Combustion,General Session Papers)

抄録

Ethanol and gasoline blended fuel sprays injected by a single hole-type injector for D.I. Gasoline Engine were measured by using the Laser Absorption Scattering technique that simultaneously measures the spatial concentration distributions of the liquid and vapor phases in the fuel spray. The effects of the blended ratio of the ethanol and gasoline on the spray development and the mixture formation were investigated. The measurement results were verified by using the numerical analysis aiming to clarify the spray development and the mixture formation.
