PURPOSE:To improve the cost, the service life, and the reliability, by furnishing a temperature sensor, a current sensor, and an arithmetic processor, and getting a fuel feeding signal depending on the result of computation of the temperature and the current output. CONSTITUTION:A detector 9 is composed of a temperature sensor (such as a semiconductor sensor) 1 and a current sensor (such as a shaft resistance) 2. The detected values of the temperature and the current VT and VI are logarithmically corrected 12 and preamplified 22 respectively at the following phase, the logarithmically corrected value VT' and the preamplified value VI' are added 3 by an operational amplifier, and the added value is time-integrated 4. The resultant value is compared 6 with a standard set value (responding to the fuel consumption Q0) 5, and the fuel feeding signal 7 of an output driving device 10 is produced, depending on which a fuel feeding pump (or an electromagnetic valve) is driven intermittently for a specific period, and the fuel for the comsumption Q0 is fed. By repeating such an operation, fresh fuel of the amount required is supplied automatically on demand. |
