TYPE IDENTIFICATION SYSTEM FOR DIESEL OIL AND METHOD FOR IDENTIFYING TYPE OF DIESEL OIL

摘要

PROBLEMS TO BE SOLVED: To identify the type and distillation properties for light oils having various compositions different from each other in distillation properties in an accurate and rapid manner. MEANS FOR SOLUTION: A pulse voltage is applied for a predetermined period of time to a liquid type identification sensor heater comprising a heater and an identification liquid temperature sensor provided in the vicinity of the heater;
the light oil to be identified is heated by the heater; and
the liquid type is identified with a voltage output difference V0, corresponding to a temperature difference between the initial temperature and the peak temperature of the identification liquid temperature sensor.
