GASOLINE TYPE IDENTIFYING SYSTEM AND METHOD FOR IDENTIFYING GASOLINE TYPE

Title:

GASOLINE TYPE IDENTIFYING SYSTEM AND METHOD FOR IDENTIFYING GASOLINE TYPE

Document Type and Number:

WIPO Patent Application WO/2004/025287

Kind Code:

A1

Abstract:

The types of gasoline having various compositions with different distillation characteristics are identified accurately and quickly. A pulse voltage is applied for a predetermined time to an identification sensor heater having a heater and a liquid temperature sensor for identification arranged in the vicinity of the heater, so that a gasoline to be identified is heated by the heater. The type of gasoline is identified by a voltage output differential (V0) corresponding to a temperature differential between the initial temperature and the peak temperature of the liquid temperature sensor for identification.
