Summary:The present invention relates to the measurement of gasoline volatility characteristics, and is directed in particular to the provision of an ultrasonic-type gasoline characteristic determination method and apparatus capable of determining the volatility characteristics with good accuracy by measuring the velocity of an ultrasonic wave in a gasoline containing alcohol or other additives and by compensating for deviations from a reference temperature, and a method for determining gasoline volatility characteristics by using an ultrasonic wave is provided, comprising the steps of transmitting an ultrasonic wave into a gasoline being measured, measuring the velocity of the ultrasonic wave in the gasoline, and determining the volatility characteristics of the gasoline from the velocity.
