<P>PROBLEM TO BE SOLVED: To provide a system and a method of detecting concentration which enable us to monitor the concentration of liquid fuel whether it varies to a specific concentration or not and to largely improve the convenience of concentration detection of the liquid fuel. <P>SOLUTION: The system is used for detection of the liquid fuel and comprises an internal space for storing the liquid fuel. The concentration detecting system comprises a heater, one or more temperature sensor, and a concentration computational device. The heater is placed in the internal space of the apparatus to heat the liquid fuel. Each of the temperature sensor is placed in the internal space of the to measure the temperature of the liquid fuel. The concentration computational device receives the temperature value measured at the temperature sensor, calculates a temperature change rate of the liquid fuel, and compute corresponding concentration of the liquid fuel on the basis of the temperature rate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
