In order to clarify the effects of fuel properties on the mixture formation under the stratified-charge combustion condition in a direct-injection gasoline engine, fuel concentration measurement in the vicinity of the ignition plug was established using a fast response flame Ionization detector (FID). A single-cylinder direct-injection gasoline engine, for which a Toyota D-4 engine was modified, was used. Paraffin, olefin, naphthene and ether having a boiling point of approximately 50°C, and paraffin, olefin and an aromatic compound having a boiling point of approximately 100°C were used as candidate fuels. As a result, the effect of boiling point on the mixture formation was clarified.
