Title:
APPARATUS AND METHOD FOR IDENTIFYING LIQUID TYPE OF GASOLINE
Document Type and Number:
Japanese Patent JP2004101385
Kind Code:
A
Abstract:
To accurately and rapidly identify the types of gasoline which have various compositions and have different distillation characteristics.
In the method, voltage pulses are applied for a prescribed period on a type-identifying sensor heater, which has a heater and an identifying liquid temperature sensor arranged near the heater, and the gasoline to be identified is heated by the heater, and the type of the gasoline is identified, on the basis of an output difference voltage V0, corresponding to the temperature difference between an initial temperature and a peak temperature detected by the identifying liquid temperature sensor.
