PURPOSE:To improve the start-up capability of an engine by installing separate power sources for an electric circuit for a car and an injector circuit. CONSTITUTION:To an engine key switch 16, a main battery 18, which is linked to an electric circuit for a car, is connected. A sub-battery 40 is connected with a resistor 34 through the second electric route 38. At the time of engine start-up, the electric equipment for the car and that for an injector are operated by separate power sources, and constancy of voltage in electric supply to the injector is thereby ensured. Accordingly, the start-up capability of the engine especially at the time of low temperature can be improved.
