<P>PROBLEM TO BE SOLVED: To easily and accurately obtain the composition ratio of fuel and to reflect it on control of an engine or a fuel cell. <P>SOLUTION: When there is change in the opening/closing state of a fuel feeding port 3 or the power source state of an engine control device 1, the remaining fuel amount in a fuel tank 4 is obtained by a fuel monitor 14, and whether fuel should be replenished or not is determined. When fuel is replenished, information on the position of a vehicle is obtained from a navigation system 2, location for feeding fuel is identified from the position, and the composition of the fed fuel is read from a fuel replenishing location database 15. Fuel composition before fueling is read from a fuel information storing part 16. From the fuel composition before fueling, composition after fueling, and the ratio of the replenished fuel, the fuel composition after fueling is calculated and stored in the fuel information storing part 16. A correction factor calculating part 17 calculates a factor for correcting the injection amount, ignition timing, and idling speed from the fuel composition stored in the fuel information storing part 16, and controls the engine 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
