SYSTEM FUER DIE ERFASSUNG DER BENZINART

摘要

A system for sensing the nature of gasoline is disclosed, which comprises a capacitance type sensor for producing a first information signal representative of the dielectric constant of the gasoline; a temperature sensor for producing a second information signal representative of the temperature of the gasoline; a temperature coefficient deriving device for deriving a temperature coefficient of the gasoline from the first and second information signals; an additive concentration deriving device for deriving the concentration of alcohols in the gasoline from the temperature coefficient; a correcting device for correcting the first information signal in view of a reference temperature; and a judging device for judging the nature of the gasoline from the derived concentration of the additive and the corrected first information signal.
