Abstract:
1. An intelligent fuel oil monitoring system comprising: a fuel level detector coupled to a fuel tank of a motor vehicle and adapted to detect the amount data of a fuel oil in said fuel tank; a microcontroller coupled to said fuel level detector and adapted to receive traveling data of said motor vehicle and to establish an average speed-fuel consumption relationship curve and fuel consumption and travel distance relationship curves at different speeds and to calculate the distance the motor vehicle to travel based on the amount data of the fuel oil detected by said fuel level detector subject to said fuel consumption and travel distance relationship curve; a display unit coupled to said microcontroller and controlled by said microcontroller to display data; said average speed-fuel consumption relationship curve comprises a linear zone and a nonlinear zone; the average speed within said linear zone is directly proportional to the fuel consumption; the average speed within said linear zone is the average of the speed of said motor vehicle at the 10˜15 minutes before calculating the average speed; and the fuel consumption is greatly increased because of increasing of wind resistance when increasing the speed which falling in said nonlinear zone.
