Patent ID: 7152582

Claim:
An apparatus for identifying a liquid type of a gasoline, comprising: a gasoline liquid type identifying chamber for causing an identified gasoline introduced into a liquid type identifying apparatus body to stay temporarily; a liquid type identifying sensor heater provided in the gasoline liquid type identifying chamber; and a liquid temperature sensor provided in the gasoline liquid type identifying chamber apart from the liquid type identifying sensor heater at a constant interval, the liquid type identifying sensor heater including a heater and an identifying liquid temperature sensor provided in the vicinity of the heater, and the apparatus further comprising an identification control portion; the identification control portion being constructed so that a pulse voltage is applied to the liquid type identifying sensor heater for a predetermined time, and the identified gasoline staying temporarily in the gasoline liquid type identifying chamber is heated by the heater and the liquid type is identified with a voltage output difference (V 0 ) corresponding to a temperature difference between an initial temperature and a peak temperature in the identifying liquid temperature sensor.
