Abstract

PURPOSE: To realize a low-cost and high-accuracy display unit, by detecting the consumed amount of the fuel per unit time via the fuel jet pulse signal and then calculating the residual running time.
CONSTITUTION: The fuel jet pulse signal 1 which gives the open/close driving to the fuel jet valve synchronizes with the engine rotation, and the jet flow rate of the fuel is applied in the duty ratio which is obtained by dividing the pulse duration of the signal by the pulse cycle. The arithmetic process is given to the pulse signal supplied through integrator 2, and the integrated value is reset by timer 3 and every fixed period. The integrated value at the resetting time becomes the general sum of the fuel jet amount. On the other hand, the residual amount of the fuel in tank 7 is detected by fuel gauge 6, and then the residual detection amount of the fuel obtained through gauge 6 is divided by the output value of holding circuit 4 and at arithmetic circuit 8 and based on the fuel consumed amount per unit time in order to calculate the running time. The running enable residual time decided through the process at circuit 8 is displayed on display unit 10 after converted into the unit of the hour and the minute through unit converting circuit 9.
