PURPOSE:To improve the starting property of the engine upon re-starting at a high temperature by a method wherein the driving speed of the fuel pump is increased when the engine is in a condition of immediately after starting and the temperature thereof is high, in the engine, in which the amount of fuel is controlled by controlling the driving speed of the fuel pump. CONSTITUTION:When a starter switch 76 is put ON upon starting the engine, an engine load Q/N is operated in a control circuit 34 by the amount Q of suction air, obtained from the outputs of an airflow meter 2 and a revolving number sensor 32, and the revolving number N of the engine. Subsequently, the load Q/N is divided whether it is larger than a reference value or not and, when the decision is YES, a fuel pump controller 18 is switched to the side of high-speed operation and the fuel pump is operated in a high-speed. On the other hand, when the decision is NO, the fuel pump is operated in the high-speed same as above in case the outputs of a suction air temperature sensor 4 and a water temperature sensor 24 are higher than the predetermined values thereof, however, the fuel pump is operated in a low speed in case said outputs are below the predetermined values. |
